This waterfall plot is a recording of VE1ZZ's signal taken over the period 2130 to 2310z tonight in a bandwidth of 0.05Hz. Obviously no SLOWCW is visible at this bandwidth, but the signals appearing for 10 minutes on the hour and half hour would seem conclusive. Also, observe the frequency is more accurately on 136500 now - no longer 2 Hz high - but there is some instability during the transmission period, about 0.08Hz drift during the 10 minutes at 2230z This plot clearly shows the strength of the signal varying over the evening, although no signal indication is given, another part of this software does give the proper spectrum and hence signal strength above noise. During the 2300z transmission it was 15 to 20 above noise level in this bandwidth. This equates to 8 - 13dB S/N in the 0.25Hz (is that right ?) needed for decoding of the dot length in use. The transmission was at its strongest in the 2200z period, but I wasn't looking at the plot then to measure ! If Jack is going to continue testing then I will complete the beacon signal monitoring and logging CFAR software started a few months ago, but abandonned at that time as no one seemed to want to transmit carrier-like signals at that time. This will automatically monitor a bandwidth and look for CW / carrier signals appearing at a certain threshold above the noise, logging these to disc when thay appear.

While it certainly would be nice to have a dependable dB scale on the meter, I do not see the point of calibrating the scale to some antenna terminal reference level on LF. On UHF/microwave, dbuV or dBm scales make some sence, since these values could be related to the internal noise temperature of the receiver. In order to give some usable information (e.g. in the report exchange), the reported value should be derived from the actual field strength [V/m] or power density [W/m²] around the receiving antenna. If this is not possible, I do not see much advantage of promoting dBuV over S-units, provided that the S unit scale is linear (e.g. 6 dB / S- unit).

I heard something similar when EI0CF rang up the other day, and I was able to listen to the signals over the phone. The tiny frequency separation is neccessary so that the guys on the other side of the pond can bring high- resolution software to bear on 2 or more signals at the same time, but it certainly isn't very helpful when trying to identify signals aurally. The ferrite cores used in TV EHT line output transformers use similar materials to the SMPSU transformers - they operate at a lower frequency, so some might be more lossy, you will just have to try. The type with a metal clip are handy to wind cables round for RFI supression, but they are a slightly awkward shape for making a transformer with. Make sure you remove any thin plastic film spacers from the joining surfaces before using; the 'air gap' is good for an energy storage inductor, but not a transformer.

Two small loops spaced 1/8 wavelength (275m) and fed with 90 degrees phase difference give a 15dB F/B ratio while having a rather wide opening angle (enough to cover most of VE/W from Europe). This would bring eastbound QRM/QRN 2/3 s-points down. Spacing could be reduced at expence of the F/B ratio (abt 5dB at 100m spacing). Some years ago I have written a small turbo pascal program that simulates the radiation pattern of 2 loops or verticals (or combination of both). Initial goal was to see if a small directional receiving antenna could be made for 80/40m. If there is some interest I will se if I can adapt it for longwave. 73, Rik ON7YD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 14354 invoked from network); 31 Jan 2001 15:24:01 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by extortion.plus.net with SMTP; 31 Jan 2001 15:24:01 -0000 Received: (qmail 20991 invoked from network); 31 Jan 2001 15:26:51 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 31 Jan 2001 15:26:51 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14Nz2Q-000533-00 for rsgb_lf_group-outgoing@blacksheep.org; Wed, 31 Jan 2001 15:19:14 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from gtei2.bellatlantic.net ([199.45.40.146]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14Nz2P-00052x-00 for rsgb_lf_group@blacksheep.org; Wed, 31 Jan 2001 15:19:13 +0000 Received: from bellatlantic.net (client-151-200-118-211.bellatlantic.net [151.200.118.211]) by gtei2.bellatlantic.net (8.9.1/8.9.1) with ESMTP id KAA26430; Wed, 31 Jan 2001 10:18:59 -0500 (EST) X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Message-ID: <3A782B7D.CE47A9BD@bellatlantic.net> Date: Wed, 31 Jan 2001 10:13:01 -0500 From: "Andre' Kesteloot" X-Mailer: Mozilla 4.7 [en]C-CCK-MCD NSCPCD47 (WinNT; I) X-Accept-Language: en MIME-Version: 1.0 To: rsgb_lf_group@blacksheep.org Subject: LF: Bobek Challenge QSO ?

Also 3E5 and 3F3 and 3C90. In fact any ferrite meaterial specified as being suitable for power transformers. I don't know if torroid cores are available (Farnell do not have any), but a wide range of SMPSU transformer cores are made in it. One promising looking core for the kiloWatt region is the ETD54 and ETD59 sizes in 3C90 available from Farnell. and are specified for use up to 200kHz. For my 600W Tx I use an ETD49 core in 3C85 which looks to be the smallest useable at this level, and runs at about 50 deg after several hours transmitting at 100% duty cycle. As part of a project for the other end of the spectrum, I'm in the process of designing a 300 - 400W SMPSU for converting a 12V car battery supply to 28V so will be looking into similar sized cores as needed for 137kHz kW systems.

Why do the manufacturers still bother with S units. Why don't receivers just
measure dBuV or dBm at the antenna?

I don't think IARU has  stated a lower frequency limit, only that it should be used below 30MHz. Using a new "standard" for LF would add to the confusion which is already big enough. If it is nevertheless felt that S9 is 500µV would be better for LF then this should be made a proposal to be presented at the next IARU conferences in the three regions. 73, Dick, PA0SE

I was running Argo in 60 second dot mode and was only viewing from .921 to .924. I had selected this so I could see both your and Jim's frequency. On the Argo scale 1851 hz is 135.92105 and the 1854 hz mark is 135.92405. The 2 + minuet mark near center at the 1854 line is my reference marker on 135.924. It is about .5 hz low of the Argo line and is the reason for the .5 hz offset. http://dmcintyre.home.att.net/135923on30Jan01.jpg After reviewing all captured shots for the night I suspect your signal may be just below the frequency line at 1851 hz on Argo. This frequency line and the one at approximately 1853.6 are always present at night here so please try to avoid this frequency. Looking right at the bottom edge of the shot and on many other shots I can see what may be your signal. I'm sure sorry I missed it if that is so. Jim, M0BMU, has verified his signal at 135.924 KHz. His fast CW id can even be seen as a blur just before the first 110 second dash. I lost his signal shortly after this shot. Jim reported his insulators melted at 0130 UT. This shot was made at 0114 UT. I will be listening anytime your advise of your transmitting but looks like QRN is on the menu for tonight. 73, Dexter LAWRENCE MAYHEAD wrote: > > Hi Dexter and Larry, > Looks like Jim made it across last night,congratulations Dex and Jim. > I was on 135,919.9-,922 near as I can get but the 135,923 signal definately > Jims.

While you were beaconing last evening I noticed a strange phenomenon on your signal which I can best describe as being similar to the aircraft flutter heard on VHF. During your long bursts of carrier there was a very deep cycle of QSB, fading at least 20 dB at about 2 cycles per second (allright then Hertz). I have heard this on your signal when you have been testing previously, but have never heard such deep or rapid fading on any other 136 KHz signal. Has anyone else noticed this?

The dive in noise occurs earlier in summer (about 0300 or soon after) and later in winter. I appreciate that this does not rule out a station going to a daytime power regime, as that would change with daylight too....presumably. However what is noticable in summer is that a lot of this noise is like distant lightning crashes. They sound more like 'crunches', but provided the outlook is clear of storms in the UK and to the west, the noise drops significantly about one hour or so before dawn. Observations would suggest the main source maybe a hour east of the shadow edge at that time. I too have been surprised by the way the dual line fades out ....yes it does fade out because I have seen a weak return about 30 to 45 minutes later for about 15 mins before it goes completely. I assumed it was a trans-atlantic source, but have not bothered to try to locate it further. I see the same pattern as you and Dave. The asymmetry on opposite sides of the Atlantic is "my hypothesis", not any proven fact, but it does seem to fit the observations quite well. Now one for the lower power stations, and the hand morse stations, the improved level of ionisation in the D-layer should lead to enhanced shorter range working signals, of the order of 700 to 1500kms, even in daytime, because this is how we are receiving CFH in daytime. I would be interested in any reports of new stations worked during the next few days.

It appears that you have switched to the "two tone" system of modulation? On Spectran it appeared to be overlapping characters, perhaps 1 or 2 hz apart. Signals were not quiet as strong as observed a week ago when I check your signal last... but I see where you were picked up well in Europe. Are you able to receive the European LF hams very well at your location? Dexter in North Carolina logged his second European ham last night on QRSS...but he is right by the coast in a good low noise location. So far, I have only been able to receive your beacon and the AMRAD beacon...nothing yet from across the pond.

They were strongest at 02.00 and 03.00 and at a steady slightly lower level from 04.30 until 06.18 when they disappeared simultaneously with a big drop in QRN(QRM?) Signal A is slightly weaker but they follow the same pattern of strength. The Loran line is strongest during the day time and weaker at night with dips at 04.00 and a big dip at 05.30, but then recovering strongly. Signal C is only seen at night. It was strongest at 01.00 and disappeared suddenly at 06.18. The pattern of changes in strength is different from that for Signals A and B.

What we need to establish is: Is this really 'oncoming daylight', that is at a different time for each latitude, or is it one event (for instance an Eu transmitter switching to low power) that is related to daylight at one location? In other words, do Geri and Marco see the effect at the same time as each other but at an earlier UTC time to the UK? > My explanation of this 6dB decline is the shutting down of the area of > received signals (including the storm areas) as daylight approaches. > Our biggest area of noises in the UK is to the east.

I have never before seen such a clear description of why this non- reciprocal effect happens. Thanks. Another interesting clue is given by the double wobbly lines very close to 137.790kHz and about 1Hz LF of Larry's beacon. I thought this was local to me but I see exactly the same on G3YXM's plots (see http://www.wireless.org.uk/newspic42.htm). My noise level takes a dive shortly after these lines suddenly stop. Dave seems to have exactly the same effect as can be seen from his third graph (note that the AGC in Argo causes the VA3LK signal/noise to improve but not the apparent background noise). How widespread is the reception of these lines (Dave and I are about 130km apart)? What are they? Do they disappear because of propagation, or something stopping transmission? There is plainly a lot to learn and investigate here.

It was raining a lot, and one of the insulators on the antenna melted, which is why I shut down early. I received a very welcome report from Dexter, W4DEX, and an Argo (mode:60s dots, fast) screen shot showing my signal as received around 0100. The sequence of 5 dashes is very clear, and the CW ID shows up as a shorter dot in the right place. This is the first time my signal has been positively identified in the USA, so many thanks to Dexter.

This is confirmed by observations on Spectrogram that Brian made in Portugal. The noise seems to make a steady decline but the effect is most noticable on a waterfall display about 1 hour before sunrise in the UK. The reponse of a waterfall is different to that of my CFH plots, as the latter are processed to remove sharp spikes of noise, such as static crashes, which may play a big part in the nightime noise pattern. Interesting plots are for following dates:- Oct 26th Nov 15th Dec 14th Dec 15th Dec 18th if you look at the periods when the carrier was cut. I also have a plot where CFH was off for the 16 Dec that I did not lodge with Rik, there is a lot local static (rain?) noise at one stage and much qrm around 137.0 in the morning (G8RW), but that shows a decline of 'non-local' noise of 4-6dB between 2400z and 0600z These graphs may not be as dramatic as is seen on some waterfalls as they are taken with a long time-constant and a form of 'averaging' which only records the lowest of 6 sequential measurements. I still have all the raw data for these dates and could replot all the data 'averaged' instead of 'censored' which might give an indication of the 'subjective' noise levels as well. My explanation of this 6dB decline is the shutting down of the area of received signals (including the storm areas) as daylight approaches. Our biggest area of noises in the UK is to the east. The effect may be different in central Europe, it should be essentially symmetrical. This is based on the opposite effect which occurs in Canada where the S/N is best in the early evening, and degrades about 4 hours after sunset. To this is added the fact that most local noise sources are generally quiet for a hour or so after dawn.

Martin G4FKK >>> Walter Blanchard 31 January 2001 07:51:29 >>> For some reason this didn't seem to make it onto the reflector first time round so here goes again: Recent discussions on "CW" and "Morse" have brought up some interesting points. Does a mode that is only visually recognisable via a machine count as "Morse" , or is it another manifestation of digital modulation? If the effective bandwidths used with QRSS are in the sub-Hertzian range does that make normally-sent "Morse" a wideband mode that should have no place at LF? Consider : "CW" - "continuous wave" - means just that; a steady unbroken unmodulated carrier wave; "N0N" (or "A0" in old money). Morse code is mainly sent by interrupting the carrier so how can it possibly be "CW"? Only amateurs consider "Morse" and "CW" to be synonymous which is a pity because it clouds our thinking. Sending Morse code by interrupting the carrier is designated "A1A" (or "150HA1AAN" for typical ham morse if you want to be pedantic!) - meaning a single carrier amplitude-modulated by a telegraphy signal. Amplitude modulation (on/off keying) always generates sidebands so it is by no means "narrow-band" by modern standards. In fact, the faster Morse is sent the more continuous and wider are the sidebands; the extreme example of a fast interrupted-carrier system is radar pulsing on/off in nanoseconds and look how wideband that is. So, "QRSS", because it switches only slowly and at long intervals is much more entitled to the narrow-band designation than normal Morse and therefore has more entitlement to be in the "narrow-band" segment. Nobody has defined when exactly slowly-sent Morse ceases to be A1A and becomes N0N. Perhaps we shouldn't press the point, we don't have "N0N" in our licenses! And what constitutes a QSO under QRSS conditions? The exchange of information presumably, but what should be the minimum time-lapse between sending and receiving? Seconds? Minutes? Hours? Days? If I send you a letter (or even an email) and you reply days later I have achieved communication with you and the time-lapse is relatively unimportant so why should radio be different? Just perception?. Then, perhaps we should have different categories of contact. An "instant" QSO using "fast" Morse such as we all know and love from HF is quite difficult to do at LF other than at relatively short ranges. To go Transatlantic in this mode will require a very "full" 1 watt plus two very sophisticated Morse ears and a lot of luck and is probably not open to those who don't have the real estate and cash to put up semi-professional antenna farms. Nevertheless we don't begrudge the lucky few who can do so their contest wins on the HF bands so we shouldn't here either. So, one category for "fast" modes with the proviso that they must complete a specified minimum QSO within, say, one minute. Coming down from such heights we get the many who can only put up "small" antennas and will get electrocuted if they try pushing them to 1 watt radiated. Their only hope is visual QRSS so a second category for "slow" modes which would have to complete a QSO within, say, one hour. Please, no arguments about "players" versus "gentlemen" - you might end up in the wrong category! Walter G3JKV.

For this to happen, a good S/N must be available for several hours. Perhaps it would help if several people reported exactly when their noise went off at dawn on one particular day, perhaps this coming Sunday. Most of us are assuming that it is caused by something local, such as street lights or neighbours' SMPSUs in 'off' mode. A coordinated test will show whether the effect is random, or related to a specific time in UTC, or related to local sunrise (propagation based effect).

Does a mode that is only visually recognisable via a machine count as "Morse" , or is it another manifestation of digital modulation? If the effective bandwidths used with QRSS are in the sub-Hertzian range does that make normally-sent "Morse" a wideband mode that should have no place at LF? Consider : "CW" - "continuous wave" - means just that; a steady unbroken unmodulated carrier wave; "N0N" (or "A0" in old money). Morse code is mainly sent by interrupting the carrier so how can it possibly be "CW"? Only amateurs consider "Morse" and "CW" to be synonymous which is a pity because it clouds our thinking. Sending Morse code by interrupting the carrier is designated "A1A" (or "150HA1AAN" for typical ham morse if you want to be pedantic!) - meaning a single carrier amplitude-modulated by a telegraphy signal. Amplitude modulation (on/off keying) always generates sidebands so it is by no means "narrow-band" by modern standards. In fact, the faster Morse is sent the more continuous and wider are the sidebands; the extreme example of a fast interrupted-carrier system is radar pulsing on/off in nanoseconds and look how wideband that is. So, "QRSS", because it switches only slowly and at long intervals is much more entitled to the narrow-band designation than normal Morse and therefore has more entitlement to be in the "narrow-band" segment. Nobody has defined when exactly slowly-sent Morse ceases to be A1A and becomes N0N. Perhaps we shouldn't press the point, we don't have "N0N" in our licenses! And what constitutes a QSO under QRSS conditions? The exchange of information presumably, but what should be the minimum time-lapse between sending and receiving? Seconds? Minutes? Hours? Days? If I send you a letter (or even an email) and you reply days later I have achieved communication with you and the time-lapse is relatively unimportant so why should radio be different? Just perception?. Then, perhaps we should have different categories of contact. An "instant" QSO using "fast" Morse such as we all know and love from HF is quite difficult to do at LF other than at relatively short ranges. To go Transatlantic in this mode will require a very "full" 1 watt plus two very sophisticated Morse ears and a lot of luck and is probably not open to those who don't have the real estate and cash to put up semi-professional antenna farms. Nevertheless we don't begrudge the lucky few who can do so their contest wins on the HF bands so we shouldn't here either. So, one category for "fast" modes with the proviso that they must complete a specified minimum QSO within, say, one minute. Coming down from such heights we get the many who can only put up "small" antennas and will get electrocuted if they try pushing them to 1 watt radiated. Their only hope is visual QRSS so a second category for "slow" modes which would have to complete a QSO within, say, one hour. Please, no arguments about "players" versus "gentlemen" - you might end up in the wrong category! Walter G3JKV.

I am using a K9AY antenna for receiving (cardioid pattern) and when I point the "null" toward the QRM from the south, the signals from Iceland pops up with "local quality"! Last winter I tried hard to hear Iceland on LF but most of the time I was only able to detect the presence of the carrier. Now, the signal is strong enough to enjoy the program with a simple AM receiver. At the time of this writing, Iceland is booming in on 189 kHz but the "Loran rattle" on 136 kHz, which is usually clearly audible, is not there... CME? Also, I have noticed a *very* pronounced "Luxembourg effect" on the Donebach signal on 153 kHz during the recent nights. A lot of programmes were heard simultaneously. Sometimes Radio Norway (1314? 630?) sounded almost as strong as the original modulation! I find this hard to understand since the "ionospheric modulator" (Norway) is *NOT* between me and the LF TX! Has anyone else noticed this? 73 Johan Bodin, SM6LKM From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 14657 invoked from network); 30 Jan 2001 23:09:33 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by excalibur.plus.net with SMTP; 30 Jan 2001 23:09:33 -0000 Received: (qmail 4496 invoked from network); 30 Jan 2001 23:03:38 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 30 Jan 2001 23:03:38 -0000 X-Priority: 3 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14Nji0-000025-00 for rsgb_lf_group-outgoing@blacksheep.org; Tue, 30 Jan 2001 22:57:08 +0000 X-MSMail-Priority: Normal Received: from finch-post-10.mail.demon.net ([194.217.242.38]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14Njhz-000020-00 for rsgb_lf_group@blacksheep.org; Tue, 30 Jan 2001 22:57:07 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from alg.demon.co.uk ([194.222.171.80]) by finch-post-10.mail.demon.net with esmtp (Exim 2.12 #1) id 14Njhm-0005C5-0A for rsgb_lf_group@blacksheep.org; Tue, 30 Jan 2001 22:56:54 +0000 Message-ID: <3A77472A.904EC86@alg.demon.co.uk> Date: Tue, 30 Jan 2001 22:58:50 +0000 From: "Steve Rawlings" X-Mailer: Mozilla 4.6 [en-gb]C-CCK-MCD NetscapeOnline.co.uk (Win98; I) X-Accept-Language: en-GB,en MIME-Version: 1.0 To: "LF Group" Subject: LF: 3C85 Material: Obsolete?

Over the past two years, I have tried to keep in touch with those active LF operators who do not monitor this Reflector. Prompted by your excellent initiative, I propose to write to the 20 active and 'dormant' 136 kHz operators in the UK who are not in the LF Group, and include a copy of: - your original Email suggesting more activity on Saturday & Sunday mornings; and, - your Email summarising the results. (Dick, I trust that this is OK with you. Let me know if you would prefer that I did not include your Emails.) As a member of the G-QRP Club, I will also write to the editor of SPRAT, offering to write an article about 136 kHz. I've also updated my web site to further encourage newcomers to start building, suggesting that those interested try listening on Saturday and Sunday mornings.

I presumed the cause was the street lights, but the timing is different. And about AGC off in ARGO, it is the only good way to use it. AGC off on the RX also, and careful audio regulation reducing the RF gain.

I haven't monitored for Larry since I managed to get a complete sequence a week ago now, but it begins to look as though I was just lucky, judging from the reports from others. So I shall have another go tonight. The pre-dawn period does appear to be best for Larry, but I suspect that this may not be true for Jack, based on previous monitoring, i.e. the best time may well depend on where the station is in the U.S. or Canada. The CFH peaks were earlier in the night were they not? It was also interesting to see how several others have had this experience of the QRN almost suddenly disappearing around 6 ish (it occurred at 6.20 when I first saw it), but I am not convinced that we know the reason yet. I also agree that Solar maximum is probably not a good time for these experiments and anticipate that by the time of the minimum, transatlantic QSOs on LF may well be commonplace. You mention that one of the other dual lines about 0.5Hz higher in frequency fades out about 30 minutes earlier than Larry. I too had seen this. It is the higher frequency one at almost exactly 137790 to within 0.1Hz. It would be interesting to know what and where the transmitter is. The modulation is too high a frequency for us to see it with Argo, but may contribute to the fading and blurring that I see. By the way the strong line at 137763.8 appears to be a DCF42/DCF49 intermodulation spur as described recently by Markus. This frequency fits exactly the formula he gave. 73, John, G4CNN _______________________________________________________ Send a cool gift with your E-Card http://www.bluemountain.com/giftcenter/ From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 21215 invoked from network); 30 Jan 2001 14:28:57 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by extortion.plus.net with SMTP; 30 Jan 2001 14:28:57 -0000 Received: (qmail 20807 invoked from network); 30 Jan 2001 14:31:48 -0000 Content-Transfer-Encoding: 8bit Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 30 Jan 2001 14:31:48 -0000 X-Priority: 3 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14NbhA-0005uA-00 for rsgb_lf_group-outgoing@blacksheep.org; Tue, 30 Jan 2001 14:23:44 +0000 X-MSMail-Priority: Normal Received: from mail.cc.kuleuven.ac.be ([134.58.10.6]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14Nbh5-0005u5-00 for rsgb_lf_group@blacksheep.org; Tue, 30 Jan 2001 14:23:40 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from LCBD15.fys.kuleuven.ac.be (LCBD15.fys.kuleuven.ac.be [134.58.80.15]) by mail.cc.kuleuven.ac.be (8.9.3/8.9.0) with SMTP id PAA115296 for ; Tue, 30 Jan 2001 15:23:23 +0100 Message-ID: <3.0.1.16.20010130161418.083f4314@mail.cc.kuleuven.ac.be> X-Sender: pb623250@mail.cc.kuleuven.ac.be X-Mailer: Windows Eudora Pro Version 3.0.1 (16) Date: Tue, 30 Jan 2001 16:14:18 To: rsgb_lf_group@blacksheep.org From: "Rik Strobbe" Subject: Re: LF: Earth Rods / Spectrograms In-reply-to: <33383892.980862121965.JavaMail.imail@bronty> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii; format=flowed Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: >I was really amused at the 'China Syndrome' thought.

He made many voygages to the new world,but became disenchanted with a life at sea,which consisted of daily grog and ship's biscuits. He yearned for more excitement and decided to study for his masters ticket. Whilst perusing the Naval Archives he read of the exploits of the notorious Captain Bligh and promptly followed his example. The mutiny was a bloodless affair and at the same time he applied to change his name,by deed poll, to Captain Horatio Fetblower and took over the Captaincy of the sloop 'Macaroni '. Realising that a return to England would mean life imprisonment in Picketts Lockup,the crew of Loafers voted to head for the nearest island. This proved to be inhabited by numerous dusky maidens,to whom Fetblower was extremely partial. The sloop was beached and the island was explored. He was intrigued by the method of hut constuction,namely basket weaving between upright stakes and there and then got the idea for his new loading coil. There was a copious supply of barbed wire already tapped in the cargo, together with semi-conductors and emigrating bus conductors.

Later, I received VA3LK - weakly around 0445, but good copy from 0650 - 0800, as observed by others. Although in the last week or so Larry's signals have probably been strongest at times between 0000 and 0300, they are more erratic and suffer greater QRN during this period. On balance, most consistent copy appears to be around dawn here. Reading through some of the older radio literature, it is apparent that the term CW came about to distinguish it from the many other types of morse code telegraphy that existed at one time or another. Spark transmitters were apparently quite distinctive according to how the spark was produced, eg. quenched spark, synchronous and asynchronous rotary gaps, etc. The "musical" note of the resulting signal seems to have made up to some extent for the wide bandwidths, and lack of receiver selectivity. The Poulsen Arc transmitter had to use a type of FSK, in order to avoid switching the arc off. The only CW transmitters were HF alternators. The early valve transmitters were often anything but CW; rectifiers did not come until later, and the transmitter was basically a big oscillator fed from whatever DC-ish supply was available. The only truly "continuous wave" signals would have been produced by battery supplies, but these were the exception. Most transmitters seemed to get HT power via some sort of rotating machine, with inevitable ripple, or even raw AC, so most of the transmitter signals would have been modulated to a greater or lesser extent, in frequency as well as amplitude. In those times, the "T" of an RST report would have had more meaning! Even after well smoothed DC supplies were available, there seems to have been operational advantages to having additional modulation to the on-off morse keying. So there was modulated CW, and interrupted CW. I think MCW of a sort lives on in some MF beacons. MCW was also supposed to have advantages on HF under selective fading conditions. Also, a non-oscillating detector (eg. a crystal) could be used. But I expect some of the older subscibers to this reflector know more about this. The last lot of transatlantic tests in the 1920s saw quite a bit of debate about the relative technical merits of new-fangled valve CW and trusty dependable spark transmitters. CW won the day that time!

In the event where Rx bandwidth is less than the signalling rate, coherence between signalling elements is necessary to see the carrier frequency, as the switching now becomes sidebands that are filtered out. Therefore, one FSK tone will not be visible in narrow bandwidths where on-off keying would have been. The only solution, and not possible with a DDS source, is to use two independent frequency generators, one for each tone, and switch between them such that each oscillator stays running at a single frequency continuously. That way each tone can separately be observed at ever narrower bandwidths until it eventually pops out of the noise. The thing I ask is that the DFCW be transmitted at a rate slower than the QRSSSSSS (sic) was. Provided the source and propagation medium is stable enough, it will _always_ be possible to see a signal at a narrow enough bandwidth and this does appear to be the case. I have a raw data file recorded at 1.95Hz sampling rate of last Friday / Saturday's transmission over a 20 hour period. This has not been processed yet, but while it was being recorded, on the real time spectrum display I'm almost convinced I saw Larry's signal several times during the day as well as most of the night time period. It was very very weak, but by sighting sideways across the screen a line appeared to be there in the noise in exactly the right place. That was in a 0.008Hz bandwidth with the trace across the screen width showing 11 hours of recording. In the original representations to the Radio Agency around 1995 about getting an amateur LF allocation and setting an ERP level Julian, G3YGF, made some back of envelope calculations and, assuming 1W ERP in 1mHz bandwidth with standard propagation curves, showed that a transatlantic QSO was feasible - hence the request for 1W ERP based on this evidence, which the RA agreed to. It looks as if at long last his calculations are being shown to be reasonably accurate. It has only taken 6-7 years.

I transmitted in beacon mode, just sending my callsign, QRSS, 10 second dots from 2340 until 0035, with short breaks for monitoring VE1ZZ. He was visible at around midnight but although the signal was good the QRN level was very high. I had problems with frequency control because the outside shack temperature dropped rather dramatically and I could not initially maintain the frequency within 3Hz. At around 2315 the temperature stabilized together with the frequency, which finished up at 135912.2Hz according to my frequency counter. The transmitter was switched off at 0035 when I went to bed. In my limited experience of marginal QRSS signals I have found that slight imperfections (characteristics) went a long way to initial identification. This is because the signal is embedded in a mass of 'perfect', and often dashed Loran lines.

This field spreads out in a form of a cone (roughly), say cone (area) of influence.

Al alternative to 'brute force' to get a pipe in the ground is to use water : connect one end to a garden hose, put the pipe vertical (with the garden hose end up) and let the water flow. The pipe will gently slide into the ground, unles you have a very 'rocky' ground. Reduce the water flow for when you get the last meter in the ground and secure the pipe for some days (weeks) to avoid a 'China syndrome'. For a picture of this procedure have a look at : http://www.qsl.net/on7yd/136ant.htm#Radials BTW : if prefer galvanized iron pipes, if you have 'acid soil' it will 'eat' your copper pipe. 73, Rik ON7YD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 429 invoked from network); 30 Jan 2001 08:51:39 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by 10.226.25.101 with SMTP; 30 Jan 2001 08:51:39 -0000 Received: (qmail 19758 invoked from network); 30 Jan 2001 08:55:14 -0000 Content-Transfer-Encoding: 8bit Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 30 Jan 2001 08:55:14 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14NWS8-00045v-00 for rsgb_lf_group-outgoing@blacksheep.org; Tue, 30 Jan 2001 08:47:52 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from mail.cc.kuleuven.ac.be ([134.58.10.6]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14NWS4-00045q-00 for rsgb_lf_group@blacksheep.org; Tue, 30 Jan 2001 08:47:48 +0000 Received: from LCBD15.fys.kuleuven.ac.be (LCBD15.fys.kuleuven.ac.be [134.58.80.15]) by mail.cc.kuleuven.ac.be (8.9.3/8.9.0) with SMTP id JAA45822 for ; Tue, 30 Jan 2001 09:47:35 +0100 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Message-ID: <3.0.1.16.20010130103829.2c576c9e@mail.cc.kuleuven.ac.be> X-Sender: pb623250@mail.cc.kuleuven.ac.be X-Mailer: Windows Eudora Pro Version 3.0.1 (16) Date: Tue, 30 Jan 2001 10:38:29 To: rsgb_lf_group@blacksheep.org From: "Rik Strobbe" Subject: Re: LF: Re: VA3LK seen in ON In-reply-to: <003d01c087dc$ce1a9f60$0a00a8c0@ThreeLakes.ca> References: <4.1.20010125141716.017e5680@pop.tiscalinet.it> <3.0.1.16.20010126104930.2c07643c@mail.cc.kuleuven.ac.be> <3.0.1.16.20010126184115.2c877920@mail.cc.kuleuven.ac.be> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii; format=flowed Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: >I have just looked around and I can not find the file I referenced, please >send me a description of DFCW, I am of the impression, apparently wrong, >that DFCW involved dual frequencies, which I have interpreted as >simultaneous dual frequencies, which is apparently wrong. > >Please send a description of DFCW, I want to understand it.

First long-distance trial was in 1844, long before Marconi! In the 1860's it was found that telegraph operators could actually decode the clicks coming from the register, and the first "aural" copy of morse became commonplace. So perhaps QRSS has more in common with "original" morse than some would like to admit.....

Hello All,
 
This time nothing about  QRSSSSSSSSS, BPSK, WOBBLE and HOBBLE , DFCW, 0.00000001HZ  bandwidth, WOLF or ELEPHANT etc.. but just a simple low-tech question from a "non-digital" CW ham. :)
 
I`m looking for tube sockets  type "Magnoval". These have 9-pins and used for PL509, PL519 etc.... Is there anybody with a big old junkbox ??  Will buy or trade for something else.
Need about 10 pieces or more.
 
Hope to be back on the air again in "normal CW ". The shack here has been renewed completely (after 20 years !!) hi. As soon as the wx will be better I will change the antenna system too. Changing the top capacity wires from 5 to 15 was a lot of work but the only thing
I got was near 3amps aerial current ( 2.5 with 5 wires) but no signal gain as reported by ON6ND.This with 250 watts. Most power will be lost in the surrounding trees etc. and I guess the only thing better is getting the vertical section of the antenna as high as possible, with a
smaller topload. Therefore I will have to remove all my VHF/UHF antennas for having  a clear
space. With these 15 topload wires the garden and the house are covered with a big umbrella,
the neighbours where asking if it was a Xmas decoration !?
 
On the matter of putting copper tubes into the ground, I have done this several times with a
water hose connected to the tube. ( A wellknown method as I can see in some other mails on the reflector).This works very well and have lenghts of 4 meters driven in the ground without any problem. ( 2 minutes time). Be sure to attach the hose very firmly to the tube otherwise the water will splash everywhere. Got soaked wet last time as the hose came
loose.... Lucky that it was +27C  ... hi
 
Best 73

I guess its hard to type with all fingers and toes crossed :-). Seriously though, despite the deafening silence on this group to dissuade you from this action, I for one (and I am *really* sure that I am not alone in this) would ask you not to do this. I don't agree with your opinions most of the time (now there's a bulletin) but I support your right to express them. You are quite right that humour is different in different places, that's why it is useful to add a smiley face at the end. Also I don't know if you are aware of this, but using uppercase in posts is the email equivalent of SHOUTING 6" from someones ear. I am sure that is not something that you would like people to think you are intending. Perhaps the using standard asterisks at either end for *emphasis* that I am sure you are aware of might be more suitable. Anyway, I look forward to your continued input (as I have said many times before) although it may be helpful to appreciate that we are all aware of your CW skills and the size of your installation - well done !!! However excessive repetition of this serves to lessen the regard for those achievements. We could all benefit from your sharp and active mind instead being applied to the advancement of our necessarily technological hobby as well as the modes which are the most appropriate for the narrowest allocation of any Ham band. 73s Steve Olney (VK2ZTO/AXSO - QF56IK : Lat -33 34 07, Long +150 44 40) ============================================= HomePage URLs: http://www.qsl.net/vk2zto http://www.zeta.org.au/~ollaneg Containing:- ULF, ELF, VLF & LF Experimentation InfraSonic Experimentation Laser Comms DX Amateur Radio Astronomy ============================================= From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 15339 invoked from network); 29 Jan 2001 20:10:28 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by extortion.plus.net with SMTP; 29 Jan 2001 20:10:28 -0000 Received: (qmail 22813 invoked from network); 29 Jan 2001 20:13:17 -0000 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 29 Jan 2001 20:13:17 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14NKWG-0000ZI-00 for rsgb_lf_group-outgoing@blacksheep.org; Mon, 29 Jan 2001 20:03:20 +0000 Received: from anchor-post-33.mail.demon.net ([194.217.242.91]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14NKWF-0000ZD-00 for rsgb_lf_group@blacksheep.org; Mon, 29 Jan 2001 20:03:19 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from pickmere.demon.co.uk ([158.152.117.143]) by anchor-post-33.mail.demon.net with smtp (Exim 2.12 #1) id 14NKVt-000LJv-0X for rsgb_lf_group@blacksheep.org; Mon, 29 Jan 2001 20:03:01 +0000 Message-ID: Date: Mon, 29 Jan 2001 17:49:17 +0000 To: rsgb_lf_group@blacksheep.org From: "M.J.Powell" Subject: Re: LF: Earthing References: <33110427.980710629282.JavaMail.imail@chilly.excite.com> In-reply-to: <33110427.980710629282.JavaMail.imail@chilly.excite.com> MIME-Version: 1.0 X-Mailer: Turnpike Integrated Version 4.02 S Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: In message <33110427.980710629282.JavaMail.imail@chilly.excite.com>, john sexton writes > >Hi Martin, >Glad to hear that you are getting there slowly. >You will probably get the best advice re earthing from some of the others, >but I have a couple of tips to pass on. >The antenna wire does not need to be as thick as you are proposing, 1mm >would do.

It makes use of similar techniques as used in my business (I am a drilling and petroleum engineer): use a garden water hose and connect it to the upper end of the copper rod.

When it is in deep enough, it can be pulled out, and the copper pipe tapped into the hole. When driving the steel rod, it helps to pull it out occasionally, and pour some soapy water into the hole. This makes it easier to drive in, and easier to get the rod out afterwards. You need to fix something to the rod to hold on to when you are pulling it out. I used "Mole grips". As well as AGC effects, another thing that will break up lines on a spectrogram display is any kind of limiting or overloading in the receiver or soundcard A/D converter. This is important when you leave the system running for several hours, and signal or noise levels change quite a bit. It's worth spending some time finding a gain level that gives signals well over the receiver noise level, but at least 10 or 20dB below the onset of overload.

For those who could be interested, in Spectran and Argo build 110 the brightness of the trace is computed (with AGC on) taking as reference level the mean value of the buffer. From build 113 I used, thanks to an idea from Andy G4JNT, the 25th percentile augmented by 3dB as reference. This latter value is much less influenced by static crashes, so reducing the 'hole effect' in the signal. 73 Alberto I2PHD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 7310 invoked from network); 29 Jan 2001 11:32:03 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by 10.226.25.101 with SMTP; 29 Jan 2001 11:32:03 -0000 Received: (qmail 13871 invoked from network); 29 Jan 2001 11:35:38 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 29 Jan 2001 11:35:38 -0000 Content-Transfer-Encoding: 8bit Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14NCRZ-0006Pe-00 for rsgb_lf_group-outgoing@blacksheep.org; Mon, 29 Jan 2001 11:25:57 +0000 Received: from bob.dera.gov.uk ([192.5.29.90]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14NCRX-0006PZ-00 for rsgb_lf_group@blacksheep.org; Mon, 29 Jan 2001 11:25:56 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: by bob.dera.gov.uk; (8.8.8/1.3/10May95) id LAA23446; Mon, 29 Jan 2001 11:27:17 GMT Received: (qmail 10891 invoked from network); 29 Jan 2001 12:19:05 -0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from gauntlet.mail.dera.gov.uk (172.16.9.10) by baton.dera.gov.uk with SMTP; 29 Jan 2001 12:19:05 -0000 Received: by gauntlet.mail.dera.gov.uk; id MAA01309; Mon, 29 Jan 2001 12:09:59 GMT Received: from unknown(10.71.64.31) by gauntlet.mail.dera.gov.uk via smap (3.2) id xma001139; Mon, 29 Jan 01 12:09:22 GMT Received: from frn-gold-1.dera.gov.uk (unverified) by mailguard.dera.gov.uk (Content Technologies SMTPRS 4.1.5) with ESMTP id for ; Mon, 29 Jan 2001 11:28:37 +0000 Received: by frn-gold-1.dera.gov.uk with Internet Mail Service (5.0.1460.8) id ; Mon, 29 Jan 2001 11:25:02 -0000 Message-ID: <65AECDF1F89AD411900400508BFC869F0D7572@pdw-mail-1.dera.gov.uk> From: "Talbot Andrew" To: rsgb_lf_group@blacksheep.org Subject: LF: RE: VA3LK seen Date: Mon, 29 Jan 2001 11:25:14 -0000 MIME-Version: 1.0 X-Mailer: Internet Mail Service (5.0.1460.8) Content-Type: text/plain; charset=iso-8859-1; format=flowed Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: I think those monitoring are using the latest version of Argo that allows 60 and 90 second dots. I use different software / hardware than can go arbitrarily narrow. AGC is always bad news for any automatic monitioring. It kills any record of the levels over time and is only there as a convenience for QSO type operating, not for scientific experiment. I meant to fix up the loop for listening at the weekend rather than using the big E field antenna, as others seem to getting much better copy from VA3LK than me, but got distracted by higher frequency projects so will try over the next few days to get the 1.2m loop waterproofed and set up.

Not a complete callsign as yet, but certainly 'LK' and a 'Q'. These seemed to come out of the noise for just one, or even part of one, character. This was Sat/Sun.. One thing puzzles me is that several stations seem to be looking at a much narrower screen than me - some refer to a 2Hz display. I am using the 30s dot setting in Argo which displays much more than that. It seemed the obvious thing to do but is it right? I have switched off the AGC in Argo. Although this is very efficient, it puts 'holes' in Morse elements when there is noise, instead of displaying the noise itself. In fact, the only was I can tell the noise level has changed is to look at the apparent strength of the Loran lines. This can be confusing. I will post some pictures to my web site to illustrate this. Does anyone have any other tips on using this excellent program? Also, I get tremendous QRM from the broadcast noises (Luxemburg effect?) right at the top of the band during the late evening. Are we really using the optimum frequency?

Looks like I should check the routing of messages! I have been recieving reports of possible sightings from Dexter McIntyre W4DEX in Stamfield N.C. since 24/01/01.I assumed that these were through the reflector and replied .It seems that they were direct so my replies may be puzzling. On 27/01/01 Dexter reported seeing a "Q" on my freq and sent me a jpeg. I matched this up with my sending paramerers both in freq and time and belive that there is perfect coincidence over this character and part of the next After VA3LK identified my signal because of a frequency wobble I decided that DFCW would be a better way of communicating under difficult conditions than QRSS, since it contains information in both time and frequency domains.Hence my DFCW transmissions. I am sorry if my communications seemed ambiguous! and am sending the 27/01/01 message from Dexter, his Loc. is EM95TF dist. about 6360 so in terms of Kms per watt! -----Original Message----- From: Dexter McIntyre w4dex To: laurie@g3aqc.freeserve.co.uk Date: 27 January 2001 15:00 Subject: A "Q" at 0548 UT? >Laurie, > >I let Argo run all night on your frequency.

Am I correct with my assumptions that Station A wobbles once, station B wobbles twice C three times and so on and in between wobbles one radiates a steady carrier. Each station has a unique frequency accurate of 0.2 hz. The other end will wobble back with an acknowledgement if a wobble is detected. This will count as a two way transatlantic QSO even no Callsigns are exchanged. What happens if someone throws a wobbly while he is wobbling or even worse a wobble when it should be steady carrier.

I also heard DJ9IE on CW, but no reply on my call. 73 and see you on 136 next weekend...de Rich OM2TW From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 26024 invoked from network); 29 Jan 2001 08:01:35 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by 10.226.25.101 with SMTP; 29 Jan 2001 08:01:35 -0000 Received: (qmail 12140 invoked from network); 29 Jan 2001 08:05:08 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 29 Jan 2001 08:05:08 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14N98J-0005F4-00 for rsgb_lf_group-outgoing@blacksheep.org; Mon, 29 Jan 2001 07:53:51 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from ns1.swh.sk ([192.108.125.33]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14N98F-0005Ez-00 for rsgb_lf_group@blacksheep.org; Mon, 29 Jan 2001 07:53:47 +0000 Received: from hermes.swh.sk (hermes [139.24.136.129]) by ns1.swh.sk (8.9.1/8.9.1) with ESMTP id IAA31282 for ; Mon, 29 Jan 2001 08:53:24 +0100 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from btss101a.swh.sk (btss.swh.sk [139.24.136.15]) by hermes.swh.sk (8.9.3/8.9.2) with ESMTP id IAA19134 for ; Mon, 29 Jan 2001 08:53:21 +0100 (MET) Received: by btss.swh.sk with Internet Mail Service (5.5.2653.19) id ; Mon, 29 Jan 2001 08:53:17 +0100 Message-ID: <29BDD4F529FCD311B631009027357C4E01FFD1FF@btss103a.swh.sk> From: "Gasparik Richard" To: rsgb_lf_group@blacksheep.org Subject: LF: RE: mystery station Date: Mon, 29 Jan 2001 08:53:17 +0100 MIME-Version: 1.0 X-Mailer: Internet Mail Service (5.5.2653.19) Content-Type: text/plain; charset=iso-8859-2; format=flowed Content-Transfer-Encoding: 8bit Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Hi Dave, Wolf and LF-group... Yes I was on 136.8 at 1945, but I transmited only for DL3FDO (for the test if he copied my signal). I realy can't hear anything since the roadway lights are on. Normaly the band is very quiet, but during the night time is it S9+20dB QRM. Therefore I'm on the band during the daytime only. Just working on the small receiver (PA0SE construction) to locate the source (lamp). If you want a sked, I'm QRV every weekend 0600Z - 1530Z. So, please wait a few days, it's not so easy to locate the problem if there are houndrets of lights. I'll do my best...See you on 136... 73 de Rich OM2TW > -----Original Message----- > From: Dave [SMTP:dave@picks.f9.co.uk] > Sent: 28. januįr 2001 21:01 > To: LF Group > Subject: LF: mystery station > > Who was that calling on 136.8xx at 1945 tonight.

You will probably get the best advice re earthing from some of the others, but I have a couple of tips to pass on. The antenna wire does not need to be as thick as you are proposing, 1mm would do. Most important is height (proportional to square of). Next is amount of top loading wire covering new ground. Laurie has some good ideas here. I have his conclusions archived if you haven't seen them. Earthing: Copper water pipes will bend over if you try to hammer them in. I attached a garden hose and slowly eased them down by twisting and gently pushing with the water flowing. If you are patient they will even go through hard chalk as here. It doesn't matter that the ground is dry in summer, just lay as much wire as possible and connect it to 4 or 5 earth rods. I have 10 radials each 10 metres long. There is a lot of info about earth mats in the LF handbook. Some lowfers attach it to the house earthing as well, but be careful of PME mains earthing. See the RSGB handbook's advice re PME and take it to heart. You could lose your house or worse be electrocuted. Also probably not a good idea to extend your earth below the neighbours garden. Hope to hear you on the band soon.

In particular is the earthling arrangements for which I would like advice. It is anticipated that the antenna will be a loaded vertical of around 8 to 10 meters with a top T one leg about 3 meters west the other 5 meters east.constructed out of 2.5 mm copper. As the ground is very wet at the moment it is a good time to bang in some earth rods. Here (Pangbourne) if you dig down through sandy soil for about 2 meters you come to gravel and then chalk. The water table in summer is at least 2 meters down and the soil becomes very dry. The garden is about 7 meters wide. Any ideas on how to archive an good earth relevant to the efficiency of the aerial. Have contemplated driving copper pipe down at the corners and considered driving them at an angle of 30 degrees under neighbours gardens. Could lay radials just under surface but in the summer they will be in very dry earth.

It is the only suitable mode available to most participants at the present time. There are a few experimenting with digital and psk techniques but they are very much in the minority. What is the problem.? I for one have the option to read all the hundreds of messages about these non morse modes plus sound card anomalies/variations etc which have less to do with communicating on LF than CW, but I read most of them and have not suggested they should be BANNED but make the point that I have reservations about their use on LF because of bandwidth restrictions. I do not mind listening to another persons point of view even though I might disagree. This is called freedom of expression and encouraged in a democratic society. Debate and Discussion about LF will continue with or without this LIST and in my case I have many avenues open to me. Just think of the debates that would ensue if one was banned on here for discussing the merits of CW on LF. The 80/40 m band is ideal, Internet, Radio related magazines etc but to mention a few. In case some have not noticed, in recent times debates on TV give an email address where the public is encouraged to send in their opinions for or against. In our case one's opinion is being DISCOURAGED - Censorship next !!!!!!!!!!!!!!

Both Bill and Colin have pretty good signals for this band, so I'm sure many of the 73kHz "regulars" would be able to work them too, noise levels permitting. I believe both stations are using xtal controlled transmitters at the moment, although VFOs are expected before too long. For this reason, it would be a good idea for stations sending beacon signals on the band to stick to the lower band edge for the time being. I can confirm G3XDV's observation that the Rugby transmitter is currently transmitting just a carrier, just above 73kHz. However, it seems to have significant mains ripple, and the spurs at 50Hz intervals across the band are the limiting factor for normal CW QSOs for me, although much better than the usual racket. A problem with receiving KMP and AKY was that they are on nearly exactly an opposite bearing to Rugby from my QTH, and so trying to null the Rugby noise with a simple loop does not work for me. However, in preparation for the sked, I had plumbed in a 50Hz bandwidth audio filter, and only having to listen to one noise component at a time meant both signals were quite easy to copy. Incidentally, while sorting out the filter last night, I had my receiver parked in the middle of 136kHz band. at about 2330, I noticed a rather good, 'O' copy QRSS signal from VE1ZZ sliding across the screen. It returned again at 0000, but I saw nothing at 0030. Both signals must have been close to audibility.

[snip] Here you seem, referring to average CW filters, to agree with my statement that mainly the fault lies in the receiver. With an ideal receiver (which of course doesn't exist), there would be no problems, provided that the sub-bands were adhered to. We need a project for an RX specifically designed for this band, with at least 110 dB of SFDR (or more...).

One of the challenges we all face in LF work is the _reliable_ operation of high-power CW transmitters (I have a bunch of fried Power MosFets here in the shack that demonstrate that problem). Generating large amounts of RF power with a _linear_ amplifier is even more difficult, because of the problem one faces when one tries to bias several power MosFets in parallel. (I am assuming here that most radioamateurs will try to use cheap Mosfets, not expensive RF types). Ideally, for such applications as WOLF, one would need a linear amplifier, yet what cheap power MosFets seem to like best is on/off operation :-) One approach to that problem was offered by Timothy Hulick Ph.D. W9QQ, in two papers he presented at the AMRAD Technical Symposium that was held here in Virginia on 17 June 2000. These papers: "The Digital Amplitude Modulator" and "The Digital Linear Amplifier" were reprinted in the Symposium's proceedings. 73 Andre' N4ICK From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 25203 invoked from network); 28 Jan 2001 16:16:37 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by excalibur.plus.net with SMTP; 28 Jan 2001 16:16:37 -0000 Received: (qmail 25249 invoked from network); 28 Jan 2001 16:10:46 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 28 Jan 2001 16:10:46 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14MuFQ-0000nf-00 for rsgb_lf_group-outgoing@blacksheep.org; Sun, 28 Jan 2001 16:00:12 +0000 Received: from ulexite.lion-access.net ([212.19.217.2]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14MuFO-0000na-00 for rsgb_lf_group@blacksheep.org; Sun, 28 Jan 2001 16:00:10 +0000 Received: from w8k3f0 (2Cust134.tnt11.rtm1.nl.uu.net [213.116.117.134]) by ulexite.lion-access.net (I-Lab) with SMTP id 0C419FAF3E for ; Sun, 28 Jan 2001 14:59:21 -0100 (GMT) Message-ID: <003201c0893b$3d7aaee0$867574d5@w8k3f0> From: "Dick Rollema" To: "LF-Group" Subject: LF: Signals measured Date: Sun, 28 Jan 2001 16:01:07 +0100 MIME-Version: 1.0 Content-Type: text/html; charset=windows-1252 X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.00.2314.1300 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Content-transfer-encoding: 8bit

My plea for more normal CW activity on Saturday  and Sunday morning had success. There was a healthy flow of traffic.
Unfortunately later on Sunday morning reception was hampered by interference from some electrical appliance and only loud signals could be measured and then only with diminished accuracy because the interference widened the trace on the oscilloscope.

4)  Aerial coil outside its cage. The signal was 1dB weaker than at 0816 but the same applies to DCF139 and the Greek RTTY so Dave's signal must have been equally strong with the coil inside and outside the cage.   Dave can also check that himself by listening to a strong steady signal, for instance from DCF139 during daytime.

The largest percentage of input to the reflector is relevant to LF and it is the observations of all concerned. Telling the truth about what one has observed might upset one or two persons at times when they are guilty, but the majority get on with it and take the criticism if applicable. If there is going to be any restrictions then it must be for all concerned and not selected individuals. There is one further point to consider, we have a large input here from all EU and other places beyond and sense of HUMOUR varies a LOT, so what offends one pleases another.

OK, Peter. Fair enough. In relation to the most recent incidents on 136.4 and 136.5, I think that I probably have over-exercised the point. So I apologise for that. But please keep in mind that it's also disturbing and depressing for those CW operators having to cope with high levels of QRSS in the CW segment.

The original reason for even bothering to respond to any of this was NOT to ban or get rid of CW. Those who have read my posts carefully with an open mind will see that my attitude is quite the contrary. Show me where there was any mention of restricting CW privileges. It was (and still is) the derision and put-downs directed towards those who exercise their right to engage in other modes. To understand the situation the following facts should be considered and be at the forefront of the thinking process when offering opinions. 1. Lack of CW proficiency has been used for a very long time as an instrument to exclude otherwise competent and valuable Amateur expertise from the HF Amateur bands. All Amateurs should have the opportunity to pursue their hobby on the international bands if they desire subject to reaching some agreed technical competence. Only recently has there been a push to relax this discriminatory restriction. Lets hope this fades into history in a few years time. 2. Non-CW types (as we are termed) have been treated as second-class Amateurs by those with CW proficiency for a long time. This is particularly obnoxious for those who have a high degree of technical competence (I exclude myself from this group). The exchanges from one of the most talented CW proponents on this group (according to his own estimation) is a perfect example of this. While people are complaining for the "hostile" humour, why aren't they complaining about that behaviour. I wonder why. Doesn't seem quite balanced to me - but then I am a colonial. I have received more than a few private emails thanking me for my "colonial" humour which serves (in their opinion) to counteract the negative matter posted here and privately to them. This includes a very pathetic personal attack by one the "moral-high grounders" on a very senior member of our fraternity in a private email. To that person, who knows who he is, either have the courage to make your attacks public or better still, send them to me privately - you will find that you will get as good as you give if you want to engage in that sort of pathetic behaviour. But I warn you, it won't distress me one bit. 3. When it comes to debating the allocations for CW in the LF bands the recent arguments seem a bit precious, but I think can see the mind set for this on the HF bands. On every HF band the official WIA band plans show that CW operators can operate virtually anywhere (except for beacon bands and the top half of 10m) while other modes are excluded from RESERVED CW segments (which can range up to nearly half the space on some bands). I guess it is only natural to expect the same deferential attitude on the LF bands :-) Anyway, this has grown tiresome (OK, OK, I guess I am to blame for a good part of it), but I make a plea once again to lighten up fellas. Others seem to be able to co-operate amongst themselves in similar situations. 73s Steve Olney (VK2ZTO/AXSO - QF56IK : Lat -33 34 07, Long +150 44 40) ============================================= HomePage URLs: http://www.qsl.net/vk2zto http://www.zeta.org.au/~ollaneg Containing:- ULF, ELF, VLF & LF Experimentation InfraSonic Experimentation Laser Comms DX Amateur Radio Astronomy ============================================= From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 18860 invoked from network); 28 Jan 2001 07:45:07 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by excalibur.plus.net with SMTP; 28 Jan 2001 07:45:07 -0000 Received: (qmail 29856 invoked from network); 28 Jan 2001 07:39:16 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 28 Jan 2001 07:39:16 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14MmLj-00076E-00 for rsgb_lf_group-outgoing@blacksheep.org; Sun, 28 Jan 2001 07:34:11 +0000 Received: from mailman.zeta.org.au ([203.26.10.16]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14MmLh-000769-00 for rsgb_lf_group@blacksheep.org; Sun, 28 Jan 2001 07:34:10 +0000 Received: from steve (ppp185.dyn154.pacific.net.au [210.23.154.185]) by mailman.zeta.org.au (8.9.3/8.8.7) with SMTP id SAA28791 for ; Sun, 28 Jan 2001 18:33:53 +1100 Message-ID: <003201c088fd$280b3360$0301a8c0@steve> From: "Steve Olney" To: "RSGB LF Group" Subject: LF: Fw: [Lowfer] Proposed new LF signal format Date: Sun, 28 Jan 2001 18:37:17 +1100 MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.00.2314.1300 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Oops, I meant to send it to the group !!! ----- Original Message ----- From: Steve Olney To: Stewart Nelson Sent: Sunday, January 28, 2001 7:57 AM Subject: Re: [Lowfer] Proposed new LF signal format > G'day Stewart, > > Great stuff !!!

Thank you for the opportunity to clarify my question above. Let's take a look at the 136 kHz band in more detail . . . It is my understanding that, where possible, operators try to use the following suggested bandplan: 135.7 to 135.8: QRSS ('visual CW') 135.7 to 136.0: TX tests & beacons 136.0 to 137.4: Normal ('conventional') CW 137.4 to 137.6: Data modes 137.6 to 137.8: QRSS ('visual CW') References: - http://home.t-online.de/home/dk8kw/bandplan.htm - 'Radcom', January 2000, p71 Assuming a separation on QRSS of 1 Hz, this provides the QRSS operators with, say, 150 notional channels (taking into account those frequencies displaying Loran lines, RTTY, etc.). With a separation on CW of, say, 200 Hz, the CW operators get about 8 notional 'channels' (assuming concurrent operation on 136.0; 136.2; 136.4; 136.6; 136.8; 137.0; 137.2; 137.4.). (Of course, it is fortunate that there is such diversity of interest on LF. If everyone operated only CW at peak times, 136 kHz might appear rather crowded!) For several months, the above plan worked well, and almost everyone fitted in with this agreement of gentlefolk. There were some minor transgressions, but points of view were hotly debated and resolved. Harmony and fair play abounded. Over the past six months we have seen the arrival of several UK stations with the ability to run high power QRSS. It is important to remember that the QRSS and CW modes are incompatible for continued harmony - that is, we can't mix QRSS and CW within a given operating segment. (Let me know if you would like me to clarify this point separately.) If the emerging high powered QRSS stations had stayed within the generally accepted bandplan, harmony would have continued. Recently, however, high power QRSS started appearing within, or close to, the CW segment. To understand why this upsets the CW operator, you need to be aware that: - QRSS operation within the CW segment reduces the number of notional CW 'channels'; - it was always felt that, ideally, there needed to be a guard band between the CW and QRSS segments; and, - QRSS is not compatible with CW. The first blow to CW operators occurred last year when high powered QRSS suddenly appeared during peak operating periods just below 136.0. This had the effect of reducing the number of notional CW channels from 8 to 7. (Of course, with the erosion of the guard band 135.8 - 136.0, those with only average CW filters have found that much of the lower part of the CW segment has been effectively sterilised by the high power stations on 135.95.) Most recently, it has become common practice by QRSS operators such as G3LDO to further erode the number of notional CW channels by operating high power QRSS within the CW segment. Over the past month I have heard QRSS for long periods on 136.5 and 136.3. G3LDO has also admitted to operating QRSS on 136.5 and 136.4. Last year we also heard QRSS on 137.0 and 137.1 kHz. So, there you have it. I am still puzzled: If QRSS only needs a 1 Hz bandwidth, why do the 20 or so QRSS operators need a 2.1 kHz segment from 135.7 to 137.8 kHz? I trust that this clarifies my earlier question.

Most television stations are not synched to anything but a local reference oscillator, usually a TCXO. This is a big improvement over the situation in the 1960s and early 70s, but it is not nearly as good as that period in the late 70s to early 80s when all networks' atomic-referenced sync pulses were passed directly by local stations. Back then, it was literally true that "ghost" sync bars would stand still at the same position day after day. (In locations where it was possible to overlay the video from three stations carrying the same network program, it was great fun to try to deduce either the spacing between the stations or one's own position relative to them.) Now, frame synchronizers re-sync incoming network signals, the output of videotape machines, and all other sources to the local studio reference. The network owned-and-operated stations may use atomic standards or GPS-based references, but most others don't. Sync drift is generally very slow, but it does occur in most of the country. 73, John From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 25600 invoked from network); 28 Jan 2001 01:05:18 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by excalibur.plus.net with SMTP; 28 Jan 2001 01:05:18 -0000 Received: (qmail 12348 invoked from network); 28 Jan 2001 00:59:27 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 28 Jan 2001 00:59:27 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14Mg5O-0005Ix-00 for rsgb_lf_group-outgoing@blacksheep.org; Sun, 28 Jan 2001 00:52:54 +0000 Received: from mail6.svr.pol.co.uk ([195.92.193.212]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14Mg5M-0005Is-00 for rsgb_lf_group@blacksheep.org; Sun, 28 Jan 2001 00:52:53 +0000 Received: from modem-72.belthronding.dialup.pol.co.uk ([62.136.140.72] helo=lvm) by mail6.svr.pol.co.uk with smtp (Exim 3.13 #0) id 14Mg5A-0000kN-00 for rsgb_lf_group@blacksheep.org; Sun, 28 Jan 2001 00:52:40 +0000 Message-ID: <000401c088c5$22028820$a970883e@lvm> From: "LAWRENCE MAYHEAD" To: "rsgb lf group" Subject: LF: Re.

The characters are encoded not in the tones, but the difference between the two tones, so it is not a coding scheme in the sense mentioned above. This allows some further enhancement which is simply not applicable to the other method, for example by center frequency tracking, the software can better pick the tone pairs at the limit of S/N and also truncate the scan band. Also I can't think of a another way of getting a better bit/baud ratio. BTW, the only place I have seen this used is by NASA for deep-space craft health status information. They apparently use two or three tone pairs to indicate various health states of the craft. The difference technique allows them to de-doppler shift a very, very weak signal. I was told about this about 6 months after I proposed my FDK scheme which is coming close to three years old now (and I am stilling pushing it onto a reluctant audience [-). 73s Steve Olney (VK2ZTO/AXSO - QF56IK : Lat -33 34 07, Long +150 44 40) ============================================= HomePage URLs: http://www.qsl.net/vk2zto http://www.zeta.org.au/~ollaneg Containing:- ULF, ELF, VLF & LF Experimentation InfraSonic Experimentation Laser Comms DX Amateur Radio Astronomy ============================================= From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 10964 invoked from network); 27 Jan 2001 21:21:07 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by 10.226.25.101 with SMTP; 27 Jan 2001 21:21:07 -0000 Received: (qmail 28995 invoked from network); 27 Jan 2001 21:24:42 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 27 Jan 2001 21:24:42 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14Mckt-0004IG-00 for rsgb_lf_group-outgoing@blacksheep.org; Sat, 27 Jan 2001 21:19:31 +0000 Received: from mailman.zeta.org.au ([203.26.10.16]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14Mckr-0004IB-00 for rsgb_lf_group@blacksheep.org; Sat, 27 Jan 2001 21:19:30 +0000 Received: from steve (ppp174.dyn154.pacific.net.au [210.23.154.174]) by mailman.zeta.org.au (8.9.3/8.8.7) with SMTP id IAA02300 for ; Sun, 28 Jan 2001 08:19:13 +1100 Message-ID: <008901c088a7$451390c0$0301a8c0@steve> From: "Steve Olney" To: rsgb_lf_group@blacksheep.org References: <000b01c08864$324d2e80$a10a883e@default> Subject: LF: Re: Re: Re: REALITY CHECK Date: Sun, 28 Jan 2001 08:22:22 +1100 MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.00.2314.1300 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: G'day Mal, > > If you do not have LF experience or cannot send/copy CW then your view point > is invalid.

A case of looking in your own backyard :-) That's a smiley (in email etiquette it indicates a friendly joke). A serious question now. What is the latest 136kHz bandplan ? The one I have here that I downloaded from somewhere must be wrong as it shows that normal CW has been allocated 1.1kHz out of the tiny 2.1kHz total, while QRSS has been allocated 200Hz. Could you point me in the direction of the correct info. Thanks. Anyway, you are completely right in one aspect. I am not qualified to comment about your quabbles over there. I do not possess CW skills, I don't have a LF station within 700km of me, I am not interested in contests, DX expeditions, countries worked, QSL card count, yada yada yada. I am just interested in increasing my technical skill level as I get older, greyer and balder. I had thought that was the reason we have our privileges.

I also use it on 136 rx with the pre amp in. I have found it totally stable and satisfactory for both functions. There are a couple of points about the 706 on rx. With a small antenna it is DEAF but with a large antenna like mine it is more than adequate with the internal rf amp switched on and in some cases I have to switch the pre amp off for best signal over noise. In conjunction with the 706 I use an external dsp unit that reduces the bandwidth to a few hertz. I also have the 250 hz cw filter fitted. I also use an IC 746 modified to eliminate the birdie around 137 khz, an FT 1000 and they are marginally better than the 706 with my antenna system. I have tried an FT 847 and although useable and sensitive/selective enough suffers a little from cross mod. around the 136 band. I have owned a TS 850 and TS 50 in the past and find them very good also, but no better than the above equipment with my particular antenna system, which is 3 x inv L antennas suspended from the top of a 120 feet mast and each one is 300 feet long(if you prefer metres divide by 3 to give you a rough estimate, bearing in mind that there are 39.37 inches to 1 metre, and 12 inches to 1 foot) Some one in the UK said recently that they and their friends never heard of feet and inches. The same people probably cannot COUNT either in metric without a Calculator The trend at University in recent years is to pass exams using a TICK TEST, where the answer is already in front of the student, if that fails use a Calculator and if that fails the student is stuck. The pass mark I understand is anything from 35 - 40 % who could FAIL? In my days one was expected to get a min of 60% for a pass and most achieved in excess of 70% plus. Is it any wonder we have so many DUDS. The GCSE examinations at present are graded from A - G and some are proposing A - Z so that no one will be disappointed, higher education is little better. Just think if the pass mark is as low as 35% for a subject then the person lacks 65% knowledge about the topic - UNBELIEVABLE. Is the UK the only Country that has this system. ? de G3KEV From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 7331 invoked from network); 27 Jan 2001 19:02:19 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by 10.226.25.101 with SMTP; 27 Jan 2001 19:02:19 -0000 Received: (qmail 1998 invoked from network); 27 Jan 2001 19:05:54 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 27 Jan 2001 19:05:54 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14MaVt-0003XK-00 for rsgb_lf_group-outgoing@blacksheep.org; Sat, 27 Jan 2001 18:55:53 +0000 Received: from mail2.svr.pol.co.uk ([195.92.193.210]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14MaVs-0003XF-00 for rsgb_lf_group@blacksheep.org; Sat, 27 Jan 2001 18:55:52 +0000 Received: from modem-111.antimony.dialup.pol.co.uk ([62.136.42.111] helo=default) by mail2.svr.pol.co.uk with smtp (Exim 3.13 #0) id 14MaVe-00046Y-00 for rsgb_lf_group@blacksheep.org; Sat, 27 Jan 2001 18:55:39 +0000 Message-ID: <000201c08891$f36b39e0$6f2a883e@default> From: "MAL HAMILTON" To: rsgb_lf_group@blacksheep.org Subject: Re: LF: This and that Date: Sat, 27 Jan 2001 13:52:46 -0000 MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 4.72.3110.5 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: -----Original Message----- From: Brian Rogerson To: rsgb_lf_group@blacksheep.org Date: 27 January 2001 10:31 Subject: Re: LF: This and that >Hi all, > >I say again there is no amateur ativity AT ALL in this area.

I would like to work you for my 21 st Country. I work normal hand sent/received cw. There are a lot of others about on normal cw and I am surprised that you cannot hear some of them or vice versa. I work random activity but if you let me know when you are likely to be on I will listen for you. You probably know that I have a 120 ft mast suitably endowed with antennas for LF and can run 1w erp out. A qso with you would be reasonable dx because I am the most Northern station active in England ie Scarborough/East Coast. I have worked EA xband my signal on 136 khz was 579. I also work Italy and get 589 from Tuscany and to the North OH1 and also get 589 frequently.

Some recent experiments by Lyle Kohler convinced me that the presently popular modes are far from optimum, and I have written a program to show the potential of a new mode. I call it WOLF (Weak-signal Operation on Low Frequency). A while ago, Lyle comparison tested various systems commonly used for amateur LF communication. Modes tested included conventional CW, QRSS (decoded both visually, and aurally with CRUNCH), and several PSK formats. Using an audio editor, Lyle mixed an attenuated copy of each signal with a "standard" sample of noise recorded from an LF receiver. He measured the maximum attenuation which each mode could tolerate before copy became impossible. The results can be seen on his Web site at http://www.computerpro.com/~lyle/weaksigs/weaksigs.htm . My present software is essentially an off-line demo. The transmit mode creates a .wav file; the receive mode reads a .wav file and attempts to decode the message. So far, it has only been tested by mixing the Tx output with noise downloaded from Lyle's site (I am traveling and have no LF Tx or Rx capability). But the simulated results have been quite encouraging; there is often good copy when the attenuation is 44 dB. This is a signal 11 dB weaker than that which was needed by BPSK at MS1000, and 14 dB below the threshold for 0.4 WPM QRSS. I would greatly appreciate any suggestions for making this system even more robust, and encourage anyone interested to download the software and try it. A simple test would be to mix the Tx output with your favorite QRM or QRN and see how it fares. Much better would be trying it on the air. If you have an SSB rig which can output LF, just play the WOLF output file, feeding the transmitter audio from your sound card. At the receiving end, record a .wav file from the receiver audio, and feed it to WOLF for decoding. If you need a different format file to key your Tx in BPSK, please let me know and I'll try to provide it. Below is a brief description of the WOLF signal; you can find more details, and the software, at http://www.scgroup.com/ham/wolf.html . Some features of this format are: * An explicit reference signal for robust frequency and phase lock * Average Tx power nearly equal to PEP * Coding to minimize number of bits for a given message * Forward error correction with high coding gain * Coherent detection * Matched filter detection (bit clock derived at receiver) * Interleaving (can tolerate gaps in reception) None of these ideas are new; it just seemed logical to combine those features of modern commercial systems which offer performance gains in our environment. Most amateur weak-signal work uses some form of CW or BPSK. It is often said that, for the same PEP, BPSK has a 6 dB advantage (CW transmits only half the average energy, and half of that is carrier with no message content). However, CW's carrier is far from wasted. It enables recovery of the frequency and phase of the incoming signal, even when it is very weak. That's one reason QRSS is so popular! In contrast, conventional BPSK relies on a non-linear process to recover the carrier, and fails to lock when the S/N is very low. Bill de Carle's AFRICA avoids this problem in a clever way -- by matching the phase pattern with all possible transmitted characters. But, this requires that any forward error correction (FEC) coding be applied separately to each character, which limits coding gain. The WOLF signal is BPSK (at MS100), but after each "data" bit, a "reference" bit is added. The reference stream is a pseudo-random sequence which is known in advance by the receiver. The precise frequency and phase can be measured, even when the signal is too weak to decode the message. The reference "channel" also provides robust bit timing and framing information, so the actual message need not include synchronizing bits. The symbol set is limited to 40 (capital letters, digits, space, and 3 punctuation). This permits sending three characters using only 16 bits. A data packet is fixed at 15 characters (80 bits), enough to send two call signs plus some report information. A rate 1/6 convolutional code is applied to the entire packet, resulting in a 480 bit message. Including the reference bits, a frame has 960 bits, so it takes 96 seconds to send. A beacon just sends the frame repeatedly. If the signal is strong enough for conventional CW, someone tuning it in only needs to "listen" for a little more than 16 seconds to see the complete message. If some error correction is required, perhaps a minute will suffice. But if the signal is very weak, the receiving software can integrate over as many frames as needed, until good copy is achieved. For two way communication, one can send a frame, and await an acknowledgement. If not received correctly, the frame is resent, until there is enough information for correct copy. However, I believe that one could design a much more efficient protocol, which should permit a QSO to be completed within one hour, even with a signal 10 dB below the QRSS limit. See the web page for more details.

All other things being equal the bandwidth is inversely proportional to the data rate, which means the bandwith for a QRSS signal is much less than a standard CW signal. You can check this out for yourself by just looking at these signals with QRSS SW. When we do the transatlantic tests we often have a group of signals transmitting a few Hz apart and each one is perfectly readable (see Ko Versteeg's .JPG on page 98 of the LF Experimenter's book). The main limitation of having two CW signals closer than, say, 100Hz apart is the receiver filter. You can have very narrow filters. I have a level meter with a 20Hz filter that certainly selects one signal from the other and you can read CW with it provided it isn't sent too quickly. Its main problem is that it converts every bit of noise and QRM to a tone the same as the signal you are receiving and this is very 'wearing' after a short while. Most problems with receivers are due to front end non-linearity. The worst receiver I have used that has this problem is the Daytong converter. Nevertheless, this converter can provide excellent 'ears' (as G3XDV can attest) provided steps are taken to reduce the input with an attenuator and/or preselector if you are using a large antenna. The problem often arises when you change from a small antenna to a big antenna. You often see it with a special event station using a big antenna put out a huge signal but have problems hearing anyone. Seasoned LF DXpeditioners, such as the 'Two Daves and a Graham' take with them their pet receiver front end signal level box. When I operate from GB2CPM the Loran comes pounding in at S9. I have to insert some 18dB of front end attenuation plus the AIP before the weak signals become readable. I live only a few miles from Laurie, G3AQC. His signal with me is S9 +35dB. (I guess I must be as strong with him). I am able to operate on the band the same time he is on provided I use the attenuators and provided I don't get too close in frequency!

Had a couple of nice normal CW QSOs this a.m. with Mike XDV and John BDQ and heard several more while doing other jobs: ON6ND, G3XTZ, G3OLB, DJ9IE, G6RO and GW4HXO, before going out shopping and getting stuck in traffic (must build a portable rig). I found that although I am all set up for weak signal reception I am not set up at all properly for strong signals. My rig has a 500Hz filter fitted, which is far too wide for normal CW. So with another strong signal 100 Hz away, I was hard put to concentrate on one station. My CW skills were never that good and like someone else on the reflector, I had a break of 20 years when I didn't use CW at all. It is coming back slowly thanks entirely to LF which IMHO is the ideal band for beginners to improve their CW receive ability. Top band, 80 etc., is full of CW at 25 wpm and faster - there is no way I could copy that by ear. Later I got a call from Finbar, EI0CF, to tell me that he heard and called me at the end of my QSO with Mike. Unfortunately I didn't hear him because of the filter problem. At least it tells me that with a bit of effort I could be putting out a decent signal. Interestingly I have heard him on quite a lot in the mornings during the week, when there was no competition. He told me that he has moved (still at Malin Head) and has a better plot, so please listen out for him and give him a call if you can. Next project build a decent CW filter that doesn't ring and get the ant up higher. 73 to all, John, G4CNN _______________________________________________________ Send a cool gift with your E-Card http://www.bluemountain.com/giftcenter/ From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 27985 invoked from network); 27 Jan 2001 14:15:30 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by extortion.plus.net with SMTP; 27 Jan 2001 14:15:30 -0000 Received: (qmail 25355 invoked from network); 27 Jan 2001 14:18:19 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 27 Jan 2001 14:18:19 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14MW5c-0002H7-00 for rsgb_lf_group-outgoing@blacksheep.org; Sat, 27 Jan 2001 14:12:28 +0000 Received: from kuku-rwcmta.excite.com ([198.3.99.63] helo=kuku.excite.com) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14MW5b-0002H2-00 for rsgb_lf_group@blacksheep.org; Sat, 27 Jan 2001 14:12:27 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from chilly.excite.com ([199.172.153.77]) by kuku.excite.com (InterMail vM.4.01.02.39 201-229-119-122) with ESMTP id <20010127141141.NSFC12117.kuku.excite.com@chilly.excite.com> for ; Sat, 27 Jan 2001 06:11:41 -0800 Message-ID: <8357038.980604701571.JavaMail.imail@chilly.excite.com> Date: Sat, 27 Jan 2001 06:11:35 -0800 (PST) From: "john sexton" To: rsgb_lf_group@blacksheep.org Subject: LF: Peaceful coexistence MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 8bit X-Mailer: Excite Inbox X-Sender-Ip: 62.253.64.5 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Hi All, In the interests of restoring amicable relations all round, can I suggest that in addition to space division (frequency band plan) we also use time division, i.e. agree some nights each week free of high power QRSS to give the CW guys a fair crack of the whip. That should also reduce friction, because we would all know when a conflict might occur and when it should not. Can I also suggest that the power used is no more than is required for the job, i.e. for QRSS or for that matter normal CW, power should be reduced for local and middle distance contacts. Where circumstances require a departure from the plan, for example because of exceptionally good conditions or restrictions on frequency range available, that as much notice as possible be given via the reflector. Equally if someone plans a CW evening or whatever, it might be wise to mention it on the reflector. I recall that Steve already does this, especially when he is planning to use the balloon.

Whatever your view such comments do not help one iota. Steve GW4ALG made some valid points and a less hostile response from someone who earlier in the week was recommending a code of practice would have been appropriate. We all know you are not a cw operator and clearly feel strongly about that. However cw is very far from dead in amateur radio terms as a quick listen on the hf bands during any dxpedition or contest will show - it is actually increasing. Have a listen on top band tonight, I expect CQWW 160 cw is just as busy with you as it is here.

In common with several other LF experimenters in the UK, I have four 1W QRSS stations within 200 km of my QTH. Now, consider the impact when a high power QRSS operator fires up on 136.5: CW operators with average receive filters will find that the resulting S9 + 20 dB signal effectively 'sterilises' the band from 136.2 to 136.8 kHz for several hours. In addition, the almost constant S9 + 20 dB QRSS on 135.9 already sterilises the band up to 136.2 - depending, of course, on the shape factor of the IF filter in use. Rik wrote: > . . .

All QRSS transmitting actvities (in > Europe) have either been below 136.0 or above 137.6kHz. If only this were true. Although G3LDO later apologised for running QRSS on 136.5, it was a hollow apology. Within a couple of weeks he was at it again - this time on 136.4 kHz (with no apology). I have certainly heard QRSS on 137.0 and, last weekend, there were also two QRSS signals on 136.3 kHz. The regular TV watchers can probably cite more instances. On the other hand, I have _never_ heard any CW in the QRSS segment. Rik wrote: > I see no reason why QRSS and CW can not co-exist. Unfortunately, these two modes are incompatible: they have to be separated through band-planning. You would have to be a CW operator to fully appreciate the limitations of CW filters when an S9 + 20 dB carrier suddenly appears 200 Hz away from the wanted S3 signal. Rik wrote: > One of the most facinating aspects of amateur radio is 'breaking > frontiers' and that is excatly what the QRSS transatlantic tests > are all about. I agree. But, if QRSS is such an ideal mode, why do QRSS operators need to use the whole of our tiny 2.1 kHz allocation to do it? John wrote: > Don't let's start slagging one or another off.

Timed transmit periods will avoid QRM at this end. callsigns abbreviated after first time. etc. 73 David 73 David From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 21581 invoked from network); 27 Jan 2001 01:19:21 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by extortion.plus.net with SMTP; 27 Jan 2001 01:19:21 -0000 Received: (qmail 21623 invoked from network); 27 Jan 2001 01:22:06 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 27 Jan 2001 01:22:06 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14MJuW-0007Ge-00 for rsgb_lf_group-outgoing@blacksheep.org; Sat, 27 Jan 2001 01:12:12 +0000 Received: from imo-d07.mx.aol.com ([205.188.157.39]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14MJuU-0007GY-00 for rsgb_lf_group@blacksheep.org; Sat, 27 Jan 2001 01:12:11 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from G0MRF@aol.com by imo-d07.mx.aol.com (mail_out_v29.5.) id l.96.f436c1a (3933) for ; Fri, 26 Jan 2001 20:11:26 -0500 (EST) From: G0MRF@aol.com Message-ID: <96.f436c1a.27a37a3e@aol.com> Date: Fri, 26 Jan 2001 20:11:26 EST Subject: Re: LF: LF tests To: rsgb_lf_group@blacksheep.org MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII; format=flowed Content-Transfer-Encoding: 8bit X-Mailer: AOL 5.0 for Windows sub 105 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: In a message dated 1/26/01 9:30:46 PM GMT Standard Time, john.currie@ns.sympatico.ca writes: << Jack and I are talking about getting together again either next weekend or the one after.

I am trying to arrange operation from GB2CPM. It was prompted by G4JNT's suggestion of a joint effort. The advantage of this location is that it is electrically quiet and there is a large antenna installed. The down side is there is no shack - I usually use my 4WD - see LF Book.

Dear All
 
I am a to small radio amateur compared from what I see here on the reflector .
To give comments on behave .
But I was so happy in September 98 , to hear normal CW which I could follow .
I started immediately to make a antenna a coil and a transmitter . And suffered a lot ,
to pick-up my CW again . Almost lost during 30 years .
I also asked Dick PA0SE to stop his beacon , because He used the complete band ...And He did !!!!
Sorry Dick I still be ashamed when I think abt it  .Now my receiver is 80 Hz bw .
So I learned a lot of things , and even more , on the LW .
In the main time I have abt 60 QSL cards all direct , and  most of them with schemas and pictures .
And even a first 5-5-9 from Italy .  Was radio ever so exiting ??? 
So I would say . Let us make a QSO , to find out how fare one can hear us , not see us   [ that is with a binocular ]
And just call CQ , and listen to the surprise . I am always happy when I hear Ronald G8RW He was My beacon .
First time He was 2-2-9 here and now with a big loop in his direction and Somme filtering He is  5-5-9 .
And even , My CW is still slow , it only takes  5 minutes fore a fb QSO .
So LF..... still FB . And a computer .....also FB . But  both at the same time  ?  Some times FB .

We have to achieve a general acceptance in the peer community, disallowing for extremist positions. For my part I have no problems with your suggestions, there as good as others and they do shorten up the QSO overal time. Sked? Certainly a Schedule, I dont see this happening any other way, for my part if I am part of it, a random QSO has as much chance as 12 inches of snow in the Amazon. In general the "RO O" etc follows the EME convention, well tested and generally accepted, again minimize exposure to raising concerns in the peer community. Your proposals are excellent, I have no problems with them providing we can keep the noise down on the validity of the QSO when it occurs. Your thoughtful effort is appreciated, Mike.

I like the use of the Es, though perhaps something a little less prone to accidental reception (S?) would be better. However, the earlier part is a bit flawed. Are you assuming that this type of communication can only be done on sked, or can there be a random QSO? If a sked, why send the complete calls? This has nothing to do with the legal requirement to identify - use 20WPM. You just need something unambiguous and if you already have a sked with M0BMU, the chances of another BMU turning up on frequency by chance are pretty remote. So just send the suffix. Jim will thank you for not having to spend an hour sending the zero! If not a sked, there is no facility for acknowledging that it is M0BMU you are replying to. You could be sending the O to anyone. Also, why send 'RO O'? Is the first 'O' a repeat back of the one sent to you? If so, there is no need to do this. Just 'R' will do - you either read it or you didn't. Incidentally, the convention for 'pse rpt' or 'agn' is just a question mark on its own. So if you didn't get the report and Jim was an 'M report with you, send '? M'. If either sked or no-sked scenario is possible, and I think it is, you need to cater for both.

Perhaps you might want to mail order it and have it shipped to your hotel. Universal Radio has it for $1399 (see http://www.universal-radio.com/catalog/commrxvr/0777.html), and so does Grove (http://www.grove-ent.com/RCV17.html), with shipping and handling within the US included in the Grove price. Also, helpful in terms of general interest might be the Lonely Planet Guide: http://www.lonelyplanet.com/destinations/north_america/boston/ Third - and striclty off topic ;-) - if you are into books, I can highly recommend Bluestocking Books. Mainly used and rare, about 5k volumes. A relatively small store run by a friendly and warm - as far as I can remember - former literature teacher at Boston College or so in her 40ies. Made some good findings each time I went there. Address is 164 Prince St., Boston,MA 02113, and phone is (617) 227-2075. Its located in a byroad up in North End, right in the middle between former Boston Garden (now Fleet Center), the bridge over to the Bunker Hill Monument and Old Granary Burying Ground (very nice, right on top of the hill, packed with Revolutionary War tumbstones and a very nice view over the Coast Guard site).

A more advanced coding schema is needed to compress this information exchange into about 2 hours or less. va3lk will present a novel FSK schema to accomplish this requirement asap. Every effort has been made to first minimize the number of bits exchanged but to also ensure that the basic minima for a valid QSO in the minds of a large number of radio amateurs has been maintained. Comments issues etc to myself please.

We have two systems, Bill de Carle has a BPSK variant that is coherent to a GPS data stream and the 1 Hz ticks fed into a computer parallel port.

Yes Rik, in fact the 6 hour QSO would be very difficult to make fly with the minimum character QSO model I am using, about 250 units of data have to be exchanged. I studied DFCW and the linear requirement is not possible of course. So I have adapted an FSK Model that I used previously for EME from 5 level to a 7 level FSK. This brings the QSO down to just under 2 hours for callsigns that are what I call "reasonable", some call signs are painful from a bit component. I will write up the minimum QSO model and the 7 Level FSK model in the near future and let them out on here. I intend to demo the FSK model as soon as a I have an DDS Exciter that will listen to a computer serial port hi. 7 level FSK might sound a bit much but when FSK steps only have to be 50 or 60 milliHz the end effect is not very painful.

The following proposal is presented as a way to make maximum use of existing skills with Visual CW and very slow bit rates that have been successful in getting amateur signals across the North Atlantic on a regular basis. The BPSK schema being proposed is more elegant and make vastly better use of the available propagation time in any one day. This email proposes a 7 level FSK coding schema for use over the North Atlantic. The schema requires a DDS level of frequency control device that can be driven from a computer serial port and is stepable in discrete steps permitting FSK levels in the order of 30 to 50 milliHz. A demonstration of this capability will be presented by va3lk in the coming weeks. The schema is based on a center frequency, called "space" which is 1/2 unit long and is the main carrier frequency of the transmission. In steps increasing in frequency, step size to be determined to fit the observing program being used, the first step represents 1 "dit", the second step represents 2 "dits", the third step represents 3 "dits". In steps of decreasing brequency, step size to be determined to fit the observing program being used, the first step represents 1 "dash", the second step represents 2 "dashes", and the third step represents 3 "dashes". really so very simple isn't it. _ < three dits _ < two dits _ < one dit -

G4GUO and myself have been thinking along the same lines for generation of MSK. While it is fine generating a constant envelope waveform at audio from a Soundcard, getting this up to RF obviously requires frequency translation. There are several options : 1) Use an HF rig and transverter. Too complex, as few operators need such a system. Although anyone equipped for PSK31 on LF will have this already. 2) Dedicated upconverter from a high 'audio' frequency as Jim suggests. The highest audio freq available is 15 - 18kHz using 44.1k sampling rate, which will need a decent bandpass filter at 137 to reject the image, but of a straightforward design / construction. WIth realistic pot-core inductors, a three pole design to cover 135 to 138 without having to tune with the band. 3) Use an I/Q upconverter and let the soundcard generate the two quadrature components from left and right channels. This will give something like 30dB isolation immediately, at the expense of a slightly more complicated mixer and LO generation, followed by a much relaxed filter spec. 4) Multiplication of the soundcard output, say by 9, from 15.2kHz; an odd number is preferable. It will be straightforward to modify the MSK modulation scheme to generate a lower modulation index, but soundcard stability becomes of paramount importance as it directly affects RF accuracy in ppm terms.

The first version wasPiccolo as designed in the 1950s by the UK Foreign Office for diplomatic comms. 32 tones corresponding to the 32 states of the 5 bit RTTY code transmitted at 100ms per tone. Various amateur reincarnations appeared over the years, with the number of tones ranging from six to 32 with assorted coding schemes. A modern 12 tone varient is often heard on 14MHz and has been around for the last year. All single tone schemes give the constant envelope advantage we want for LF, not usually an issue at HF where linear transmitters are always used.

My list would be : - suitable with non-linear amplifiers : for sake of efficiency and simplicity of the amplifier - be able to transmit at least 45 different 'characters' : - if we want to use non-linear amps we can only transmit one 'tone' at a time, so each character needs to be transitted a a sequence of 'tones'. The more 'tones' you use the shorter the sequence per character will be but the larger the required bandwidth, so we will have to find a compromize between bandwidth and speed. eg. 47 characters can be transmitted with 7 tones and 2 sequences per character (49 posibilities) or as 4 tones and 3 sequences per character (64 posibilities). An important question is : is it worth to make things that complicated ? Assume the transmission speed is 60 seconds dotlength. In that case the time needed to transmit 'CQ ON7YD K' would take : 114 minutes in QRSS 40 minutes in DFCW 30 minutes in '7 tone mode' if we have a space between characters 20 minutes in '7 tone mode' if we have no space between characters 40 minutes in '4 tone mode' if we have a space between characters 30 minutes in '4 tone mode' if we have no space between characters >From the above is clear the step from QRSS to DFCW is significant (time reduced to 35%), but the difference between DFCW and the 'multi tone modes' is between nil and 50%, so we should have to go to a rather complicated system (7 tones, no spacing) to have a significant gain.

A loop can be very efficient to null out one source of QRM/QRN, due to the very sharp minimum. Further is is rather insensitive to local electric field QRN, provided the shielding is good. But the maximum of a loop is very broad so I'm afraid it won't give any improvement in regard with atmospheric QRN. Maybe a phased array improve SNR due to directivity, at least for those who have the space and a several 100m of coax. 73, Rik ON7YD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 16163 invoked from network); 26 Jan 2001 13:08:43 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by extortion.plus.net with SMTP; 26 Jan 2001 13:08:43 -0000 Received: (qmail 9535 invoked from network); 26 Jan 2001 12:34:51 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 26 Jan 2001 12:34:51 -0000 Content-Transfer-Encoding: 8bit Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14M7ze-0003MC-00 for rsgb_lf_group-outgoing@blacksheep.org; Fri, 26 Jan 2001 12:28:42 +0000 Received: from bob.dera.gov.uk ([192.5.29.90]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14M7zd-0003M7-00 for rsgb_lf_group@blacksheep.org; Fri, 26 Jan 2001 12:28:41 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: by bob.dera.gov.uk; (8.8.8/1.3/10May95) id MAA31414; Fri, 26 Jan 2001 12:29:58 GMT Received: (qmail 2777 invoked from network); 26 Jan 2001 13:21:57 -0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from gauntlet.mail.dera.gov.uk (172.16.9.10) by baton.dera.gov.uk with SMTP; 26 Jan 2001 13:21:57 -0000 Received: by gauntlet.mail.dera.gov.uk; id NAA28270; Fri, 26 Jan 2001 13:13:07 GMT Received: from unknown(10.71.64.31) by gauntlet.mail.dera.gov.uk via smap (3.2) id xma028152; Fri, 26 Jan 01 13:12:46 GMT Received: from FRN-MAIL-3.dera.gov.uk (unverified) by mailguard.dera.gov.uk (Content Technologies SMTPRS 4.1.5) with ESMTP id for ; Fri, 26 Jan 2001 12:31:32 +0000 Received: by frn-mail-3.dera.gov.uk with Internet Mail Service (5.5.2650.21) id ; Fri, 26 Jan 2001 12:27:57 -0000 Message-ID: <65AECDF1F89AD411900400508BFC869F0D7568@pdw-mail-1.dera.gov.uk> From: "Talbot Andrew" To: rsgb_lf_group@blacksheep.org Subject: LF: RE: RE: VA3LK seen in ON Date: Fri, 26 Jan 2001 12:28:11 -0000 MIME-Version: 1.0 X-Mailer: Internet Mail Service (5.5.2650.21) Content-Type: text/plain; charset=iso-8859-1; format=flowed Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: > -----Original Message----- > PA must be linear.

TNX > 73 Alberto With the present designs a real killer ! Switching transmitters achieve well over 90% efficiency, and a conventional linear design would have 78% absolute maximum, more like 50% in reality. With kW outputs, that's a lot of heat to get rid of. The efficiency issue is why so many commercial LF transmissions use constant amplitude MSK now, having changed over from bandwidth hungry FSK. PSK, to be social, needs amplitude tailoring otherwise this would be the mode of choice. We can get away with using PSK without any complaints as we are using very low data rates, so the sidebands are not a serious problem, but there all the same. Hence my proposal for two sequential tones for a (tongue in cheek) visual human decoded system. Or a slowed down narrowband version of Piccolo. Isn't is about time some more LF operators tried BPSK - I've no one to listen out for ! But we'll have to find a new frequency, Larry is established on 137.79 now.

Transmitted the usual beacon signal on 135.923kHz last night from about 1845 to 0240. The weather was still and clear, so I did not have to keep re-tuning the antenna for once. Thanks for the reception reports - monitoring at odd times during the evening, I saw up to 3 other signals at once within a couple of Hz bandwidth, although I did not pause to identify them. I received a phone call from EI0CF, and I was able to hear my signals as received at Malin Head.

As regards simultaneous 2-tone transmission, It has been pointed out that a bi-phase PSK signal with properly shaped envelope is the same as a 2 tone signal generated by a linear (SSB) transmitter. The PSK carrier would be the mean frequency of the two tones, and the phase modulation would be at the difference frequency between the two tones. So if the mean and difference frequencies were available from sound card or DSP, it would be possible to u se a class D or other non-linear TX to generate the 2 tone signal - although it would still be a little harder to do than sequential tones.

As a general point for computer-generated signals, if the soundcard or DSP could be persuaded to generate the output at a few kHz instead of 800Hz or whatever, it would be a simple matter to mix the signal directly up to 136kHz, with a fairly simple bandpass filter to give good unwanted sideband rejection. This would eliminate the need for an HF tranceiver as an IF stage, and the resultant problems with frequency calibration and obtaining LF output with reasonable levels of distortion products.

I think VK2ZTO has already carried the multi-tone idea to one of it's logical conclusions, with seperate tones for each different alphabetical characters - see 'FDK' on his web pages http://www.qsl.net/vk2zto.

Cheers, Jim Moritz

I agree with with Rik and others that we should try some form of freq shift. Its one thing to be seen, but far better to get some information across! I have modified my driver and will transmit DFCW tonight ,using 48sec. elements,24sec. inter-element spacing and 0.15Hz shift. Lets see how that works! Regarding the extra dbs, I am only running 350mW so theres 4.5 db to be obtained from a 1W station.The other thing is what about a Loop Rx ant.? that should give a few dbs improvement in S/N due to directivity.

If it was you Laurie, your stability has infinitely improved ! ============= Re Rik's suggestions :- Why keep to two frequencies just so it looks like morse cod ? If we really feel we HAVE to keep to visual modes using Soundcards rather than using the superior capabilities given by machine decoding, how about several levels of frequency shift in say 1Hz and just learn a new visual code. Just as an example of a visual code, 7 frequency levels, using two sucessive symbols per character gives potential for 49 different symbols, enough for letters numbers and a few punctuation. There would be no need to turn off the Tx for any symbol, as a space could be coded as a character, thus removing ambiguities with dots and noise spikes. That will give those who feel the need to learn a code by rote once the CW test is abolished something to feel they've succeeded. I believe there were a few operators in days gone by who could even read RTTY and Piccolo signals by ear. Perhaps the Morse test could be replaced by a Dual-7-Frequency test for an extra class of licence.

QRN was bad, but I could make a VA out of it (with some imagination). I'm pretty sure to have seen your signal and will continue monitoring for the next days. If condx go up a bit and QRN down a bit I should be able to get a clear copy. More general : it seems that it is possible to cross the pond with stations running less than 1W ERP (believe that BMU and AQC are abt 400-500mW) but it needs rather long dotlengths (1 minute). So we want to take the next step to 2-way communication we might need a more 'time efficient' mode than straight morse code. DFCW is about 3 times faster but it needs 2 frequencies, a shift of 0.1Hz would be sufficient. More complicated 'coding' using multiple frequencies could even speed up things more, using 4 frequencies we could code 64 characters in 3 'dots'. Based on the experience that a 'very basic' QRSS QSO takes about 20 minutes at 3 sec. dotlength this would mean over 6 hours at 1 minute dotlength. With DFCW this could be reduced to about 2 hours, seems acceptable to me. Advantage of DFCW over more complicated codes is that it is 'readable' on screen if you know morse code. 73, Rik From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 12857 invoked from network); 26 Jan 2001 07:32:29 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by 10.226.25.101 with SMTP; 26 Jan 2001 07:32:29 -0000 Received: (qmail 25337 invoked from network); 26 Jan 2001 07:36:02 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 26 Jan 2001 07:36:02 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14M3Hi-0001xL-00 for rsgb_lf_group-outgoing@blacksheep.org; Fri, 26 Jan 2001 07:27:02 +0000 Received: from [195.47.110.226] (helo=dell1.gmccz.cz.gmc.net) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14M3He-0001xG-00 for rsgb_lf_group@blacksheep.org; Fri, 26 Jan 2001 07:26:58 +0000 Received: from p (p.maly.gmccz.cz.gmc.net [192.168.1.22]) by dell1.gmccz.cz.gmc.net with SMTP (Microsoft Exchange Internet Mail Service Version 5.5.2650.21) id DV58SQYQ; Fri, 26 Jan 2001 08:27:38 +0100 Message-ID: <003b01c08768$40823ec0$1601a8c0@maly.gmccz.cz.gmc.net> From: "Petr Maly" To: "136 group" Subject: LF: Visit in Boston, USA Date: Fri, 26 Jan 2001 08:18:59 +0100 MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-2; format=flowed Content-Transfer-Encoding: 8bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.00.2014.211 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Hi all Sorry for off-topic, but some u.s. colleagues may help me.

Well Laurie, your little frequency "shepherd's crook" as I call it has made you my first European for sure to be seen on LF here in Westport. Today Bill de Carle and I compared notes in a greasy spoon in Ottawa and it was funny, as we both have the same little Shepherds Crook in our data. Congratulations. We need another 5 to 10 dB of signal to make this work, I have been contemplating this all day and I will try to figure out what I can do to find that much more signal. Bill is away from his QTH until Tuesday so my plan is to ask you to make a special transmission starting 20 utc on Tuesday all night, and both of us will see what we can do to find a few more dB by then. In the mean time I am listening to the window 135.92175 to 135.9232 with 30 second ticks continuously until the end of Monday UTC. If anyone wants to join in, please get well within these limits of my receiver.

Although it was 1984 - I was only 12 years old in 1944 I had actually conceded the point when you quoted Richard Feynman but had not got round to formulating a reply. I might just be able to hang in there with Electomagnetic Theory but when it comes to Quantum Mechanics I am lost. Some time ago I bought Feynman's "Six Easy Pieces" and "Six not-so-easy Pieces" from his famous lectures. However, these books do not extend as far a Quantum Mechanics and treats Electromagnetic Theory in the traditional way. You might let me know which book or paper your Feynman quotation came from. For those of you who are may be wondering what all this is about. Roger submitted an article on a toroidal antenna to the RSGB Radcom in 1994 when I was Technical Editor. The small torodial antenna was so radical I decided to build one before publishingRegards, Initally I had no success with his original single toroid model but with more advice from Roger I got a double toroid antenna working. With a 14MHz model, 300mm in diameter and around 400mm tall I worked VK on more than one occasion. The photo Roger refers to is a radiation test being performed on this antenna. This begs the question of whether one of these antennas would work on 136kHz. The answer is probably yes - the down side is that it is rather a complex structure and would be difficult to engineer.

The distinguished hand was holding a flourescent tube in the presence of a high electrical potential which illuminated the tube. These historic photographs exhibit the first recorded experimental verification of vector potential in the radio frequency spectrum. They illustrate the time-varying potential in free space radiated by a toroidal antenna ( which emits no magnetic field and has no standing electrical charge). It cannot be explained in terms of scalar potential because there is clearly a reflection from the roof of the vehicle and further research would have shown that it travelled at the speed of light and was time varying at the frequency of transmission. Nor can it be explained directly in terms of an electric field for a field requires a difference in potential for its creation. The distinguished scientist who performed this historic experiment is known to us all. He was Peter Dodd, G3LDO. Pehaps he should be nominated for a Nobel Prize! 73, Roger, G2AJV.

I can remember in the early days of TV here in the states that we would occasionally see such things --- when they were not synched. Now you just see a stable ghost of the 'interfering' station in the background. Since TV is AM, there is no appreciable 'capture effect' like on FM and a weak signal can ghost through a marginal local signal. Just a supposition, but I think it makes sense. I suspect it makes even more sense on your side of the pond where spectrum is even more highly congested.

Clubs: The Crystal Set Radio Club] Date: Wed, 24 Jan 2001 08:15:09 PST From: rick_weber To: roneill@clark.net I was intrigued with Larry Pizzellas (Loose-Coupler) Diet Coke Can tuner when he first posted the photo on this web site.. This past weekend, I set up my own personal challenge to build a QRP CW transmitter for 80 meters that used only ONE commercial electronic component -- a vacuum tube -- and other NON-electronic junk commonly found around the house including several Diet Coke cans. This is not a crystal radio, of course, but is in the crystal radio enthusiasts spirit of minimal design and constructtion. I started with a very old 27 tetrode vacuum tube made in the late 1920s. No commercial resistors, capacitors, chokes, or variable tuners were used. Capacitors were made from Diet Coke cans and clear packing tape -- two .002 mF and one 250 pF. Made the 500 pF variable condenser from one diet coke telescoping over another one with packing tape insulation. RF choke is 160 turns of wire on a ball point pen body. The 10 KOhm grid resistor was made using the old science fair trick of a soft graphite pencil rubbed on carboard. Two paper clips provided the resistor leads. Twelve turns of wire on a plastic pill bottle for the tank coil. Swing link loosely coupled to the tank coil via an LDG QRP tuner/4:1 balun to a center-fed Zepp ant. Used the rcvr part of a Sierra as my receiver. Powered the xmtr with an old 1929 80-based power supply. The crazy thing worked! Had a QSO Tuesday night with Bob Howard K0RDF about 350 miles away. My RST -- 239. The best I could tell, this thing was putting a little under a Watt to the antenna. Heres a photo: http://www.vintagehamradio.com/junkbox-xmtr Heres the total parts list for the xmtr: 1 27 tetrode vacuum tube 5 Diet Coke cans (capacitors) 1 Plastic pill bottle (tank coil form) 2 Ballpoint pens (one for RF choke and one for tank coil form support) 1 Roll of packing tape (insulation for caps and general) 2 paper clips (resistor leads) 1 HB pencil (resistor) Wire, epoxy, nails, cardboard, wood, solder Why use a vacuum tube instead of a transistor? Im an OT radio nut. (The best QRP radios glow in the dark!) A lot of you rockheads out there who are also hams have a whole lot more ingenuity and skill than this old coot. Why not try your luck at a building something similar and let us know how it worked.

I think you are suggesting that I will have an overload problem with the IC- 706. In fact, this receiver is =very= insensitive at LF and must have a pre-amp to be of any use at all. I am using a pre-amp I bought at the RSGB HF Convention (I think designed by Dave, G3YXM?) and this has some very good front end tuned circuits. There is no sign of spurius responses. When using the very sensitive Datong converter, I certainly needed to attenuate the input to avoid overload, and my loop antenna worked into it without any additional amplification.

I transmitted the same signal as before on 135.924kHz, this time from 1900 to 0230, after which I decided it was time for bed. I saw VE2IQ's spectrogram, showing the signals he could see last night - clearly, they are on the right frequency give or take a few mHz, however, positive identification is still difficult - in the case of my signals, they appear to be still too weak or too fast(!) for the on/off pattern to really show. I will alter my frequency slightly next time - hopefully, Bill's signal will alter frequency too. If these signals do turn out to be G3AQC and myself, the difference in time between optimum reception is certainly interesting and unexpected. Thanks to G4JNT for the frequency check - I think I will leave my reference oscillator alone for the time being, it is still just about within spec, although it probably has not been set up for several years. I will try again tonight at similar times. Since Laurie is now going to 135.922, I will try 135.923 for a change. Hope this is OK. Cheers, Jim Moritz 73 de M0BMU From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 8163 invoked from network); 25 Jan 2001 15:51:35 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by 10.226.25.101 with SMTP; 25 Jan 2001 15:51:35 -0000 Received: (qmail 11975 invoked from network); 25 Jan 2001 15:55:08 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 25 Jan 2001 15:55:08 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14LoXK-000665-00 for rsgb_lf_group-outgoing@blacksheep.org; Thu, 25 Jan 2001 15:42:10 +0000 Received: from cmailg6.svr.pol.co.uk ([195.92.195.176]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14LoXG-00065x-00 for rsgb_lf_group@blacksheep.org; Thu, 25 Jan 2001 15:42:06 +0000 Received: from modem-23.belegund.dialup.pol.co.uk ([62.136.138.23] helo=lvm) by cmailg6.svr.pol.co.uk with smtp (Exim 3.13 #0) id 14LoWz-0001Ww-00 for rsgb_lf_group@blacksheep.org; Thu, 25 Jan 2001 15:41:49 +0000 Message-ID: <000201c086e5$d96547a0$178a883e@lvm> From: "LAWRENCE MAYHEAD" To: "rsgb lf group" Subject: LF: Re.

I just looked at last nights data and there are definitely some signal lines on my capture screens, this is the same I had last year when I put in several months chasing the AMRAD signals from the Washington area. I have left capture running all day today and will catch the start of things this evening. I do hope you will be transmitting again by 19 or 20 utc today. For others transmitting near Laurie's QRG, Please get within 1 Hz of the frequency Laurie is on so I can catch you in the same screen! The ARGO window is only + and - 1 Hz wide, so I need you to cuddle in a little close if you don't mind - Thank You..... Part of my work today is to take some steps to find another few dB so I can really hear/see your signals. I am trying to set a "next steps" program to resolve these issues.

Rik: Please, no assumptions! My transmitter is at my remote radio site, an ex heavy route analogue microwave radio tower (250 ft high) about 5 miles away from the village (were I stay for part of the winter) and my home a further 5 miles away on an Island on a large lake. I thought the Decca might finally bother me at home but it does not at the bottom end of the band in any case. Transmitter is and will continue to run continuously until Feb 1 when it will go down while I have fun on the FOC Marathon and then it will go back on again on February 5th. If there is a change (weather or equipment related) for any reason I will email everyone on this reflector.

Perhaps I should have made clear that with "newcomers" I did not mean newcomers to amateur radio. For those LF is not the best band to start on, I think. Moreover newcomers with interest in modern technology will probably turn their attention to UHF and SHF in the first place with the additional advantage that no morse code proficiency is required. When I mentioned "newcomers" I had in mind amateurs that have been using the existing older bands for some time and now would like to explore the new LF band. They will start by listening and in order to turn them into active users a sufficient amount of normal CW traffic should be present at times when they are able to listen and when local noise level is low. At my place the latter is the case on Saterday and Sunday morning. 73, Dick, PA0SE From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 17174 invoked from network); 25 Jan 2001 11:33:52 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by 10.226.25.101 with SMTP; 25 Jan 2001 11:33:52 -0000 Received: (qmail 24314 invoked from network); 25 Jan 2001 11:37:25 -0000 Content-Transfer-Encoding: 8bit Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 25 Jan 2001 11:37:25 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14LkZL-0004ne-00 for rsgb_lf_group-outgoing@blacksheep.org; Thu, 25 Jan 2001 11:27:59 +0000 Received: from mail.cc.kuleuven.ac.be ([134.58.10.6]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14LkZK-0004nZ-00 for rsgb_lf_group@blacksheep.org; Thu, 25 Jan 2001 11:27:58 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from LCBD15.fys.kuleuven.ac.be (LCBD15.fys.kuleuven.ac.be [134.58.80.15]) by mail.cc.kuleuven.ac.be (8.9.3/8.9.0) with SMTP id MAA79894 for ; Thu, 25 Jan 2001 12:27:46 +0100 Message-ID: <3.0.1.16.20010125131848.32c79234@mail.cc.kuleuven.ac.be> X-Sender: pb623250@mail.cc.kuleuven.ac.be X-Mailer: Windows Eudora Pro Version 3.0.1 (16) Date: Thu, 25 Jan 2001 13:18:48 To: rsgb_lf_group@blacksheep.org From: "Rik Strobbe" Subject: LF: VA3LK beacon In-reply-to: <3A70030D.8045.580470@localhost> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii; format=flowed Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Hi Larry, I'd like to give it another try to copy your beacon over the weekend as best chances seems to be just after sunrise (in Europe).

I'm using my transmitting antenna and found that I can add up to 40dB attenuation between antenna and RX (Kenwood TS440) before the bandnoise hits the RX noisefloor. I have 20dB attenuation all the time to prevent DCF39 from overloading the RX input (and causing IM products). I tried some preamps in my 'early days' on 136 but found them only a source of aditional IM products. 73, Rik ON7YD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 25436 invoked from network); 25 Jan 2001 10:50:04 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by extortion.plus.net with SMTP; 25 Jan 2001 10:50:04 -0000 Received: (qmail 19439 invoked from network); 25 Jan 2001 10:52:48 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 25 Jan 2001 10:52:48 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14LjuR-0004cZ-00 for rsgb_lf_group-outgoing@blacksheep.org; Thu, 25 Jan 2001 10:45:43 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from [213.2.16.106] (helo=rsgb.org.uk) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14LjuQ-0004cU-00 for rsgb_lf_group@blacksheep.org; Thu, 25 Jan 2001 10:45:42 +0000 Received: from miked by rsgb.org.uk with SMTP (MDaemon.v2.8.7.5.R) for ; Thu, 25 Jan 2001 10:42:22 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 From: "Mike Dennison" To: rsgb_lf_group@blacksheep.org Date: Thu, 25 Jan 2001 10:42:21 -0000 MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII; format=flowed Content-Transfer-Encoding: 8bit Subject: LF: Stability Message-ID: <3A70030D.8045.580470@localhost> X-Mailer: Pegasus Mail for Win32 (v3.12c) X-MDaemon-Deliver-To: rsgb_lf_group@blacksheep.org X-Return-Path: miked@mail.rsgbhq Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Yesterday, I commented on frequency drift seen when using extremely narrow bandwidths. I assumed the cause was my IC-706 Mk1. However, on further investigation, I found the problem was my Datong converter. This was wandering and drifting with temperature. For normal CW or even QRS this is not a problem as the movement was only one or two Hz over a period of several minutes. For 30s dot QRS it is a disaster. I am now using my IC-706 directly on 136kHz, with a pre-amp/filter and this works fine. Nothing seen of Larry yet but I have some fine photographs of noise and very stable QRM lines. Now for the transmit side. I very recently managed to persuade my keyer to give me 10s dots, but the stakes have been increased and there is no way it will go up to 30s. Next job is to build a computer/Tx interface and do everything with the PC. Those following the story of my burnt insulators may like to see the pictures which are now on my web site.

My understanding is that ZDF sync pulse form a national standard for time distribution in D Land and should be exactly 15625.000 This is borne out by German microwave opertors who use ZDF TV sync for high accuracy frequency standards and I'm told it is an inheritance from Unification where the DDR originally used this method of national time and frequency distribution. Your measurement of 0.19 Hz high suggests a soundcard sampling error of 12ppm which looks feasible. I find it hard to believe that any of the TV stations would be out by more than 30ppm even if a cheap and nasty TTL oscillator module were used - which WDR and RTL evidently are. Your measurement of ARD looks to be within tolerance of your quoted accuracy so the betting is those are the identical frequency Andy G4JNT > To verify that these differences are not propagation effects, > I also compared > some the TV line frequences (using a soundcard at > 44100samp/sec, mixed down, > decimated by 81, 64k FFT size, 0.008Hz resolution).

Well said! Geri, DK8KW (W1KW) P.S. I learned CW when I was 14 and I can say that I am a profound CW operator. Since I have started on LF, I have tried to expand my transmitting capabilities continuously, my first QSOs were in QRSS then CW, followed by BPSK, RTTY, PSK31 and, together with DF6NM I developed Slow-Voice. I love the experiment as well as the challenge, I have seen VE1ZZ and I am working to see VA3LK. To relax I like to have a normal CW QSO from time to time .... either armchair copywith 25 WPM or just below the gras-roots at 5 WPM, and I think all has it's place on LF!

Clearly a temperature effect as the transmitter cycles. If your readout accuracy is 0.05Hz, that's well within my own measurements. As for colours in bitmap files. Bill, I had exactly the same problem making a .BMP dump from the 16 colour VGA screen. You need to use the appropriate DOS interrupt to read the palette information for the 16 colours, then store this in the header of the .BMP file. I can let you have the code for this (In PowerBasic) separately. If you don't do this, a default palette is assumed which is correct for colours 0 to 7, but wrong for 8 to 15. Also any redefined colours come out wrong. Guess there may be one or two minor advantages in Windoze software !

[use monospaced font for best view] P -------W S S W----------EMF-----p"P" W S S W N -------W S S W S S-CT G ---------+ | W | W | W----------EMF-----p"N" | +---------------------pG P = phase conductor of standard mains N = return conductor of standard mains G = safety conductor of standard mains S = shields of transformer CT = center tap W = windings of transformer p"P" = private phase conductor p"N" = private return conductor pG = private safety conductor EMF = electromagnetic fuse (double sense, double throw) Note: p"P", private phase conductor and p"N", private return conductor in fact are more or less symmetrical in potential referred to pG and (capacitively) to G. Regarding case of electrical faults: fault-1 (p"P" touches pG) fault-2 (p"N" touches pG) fault-3 (p"P" touches p"N") The EMF will detect these 3 situations and will shut off both, p"P" and p"N" conductors. I think electrical shock is impossible as long as all connetions made with conductor pG are low ohmic and as long as EMF does not fail (when did you check resistance of the safet conductor in your house wiring last time? ;-). Regarding case of lightning strike: Lightning cannot strike G, nor can it strike pG directly (those conductors are underneath earth surface). Lightning can however strike outdoor equipment such as the antennas. Antennas are protected with safety spark gap (approx. 15 kV flashover voltage) connected to mentioned private grounding rod (direct electrical continuity with pG, indirect electrical continuity with G via soil). Antennas are connected via LC circuits with coaxial cables. Shields are directly connected with private grounding rod. Center conductors have arrestors outdoors and at the shack end (protection levels 1kV/250 V respectively). Coaxial cables run in steel conduit, 70 cm below soil surface for 7m length, before entering the house. I do not see any chance of built up of lethal voltages in between conductors G, pG and local soil potential. In case of direct hit of a lightning strike into antenna, the conductor pG and all metallic objects connected to it will jump to a potential Istrike times ground rod to earth resistance (6 Ohms in my case). This will happen as well if I directly connect conductors pG and G. So where is the benefit of using conductor G exclusively? CK> A few years ago somebody tried a similar isolation CK> system but conencted together the two earth CK> conductors with an inductor made of thick CK> electrical wire on a ferrite toroid. The coil CK> had very small reactance at power frequency CK> (50/60 Hz) but blocked conducted noise at radio CK> frequencies. This is a good idea as such and was taken into consideration as well. Finally I did not implement this for the following reason: Receiption on my QTH is/was impaired by common mode (noise) currents coming along the safety wire, flowing on the outside of equipment chassis, over coax shield surface and being coupled into the coax at the antenna. Those currents seem to origin from relative high impedance voltage sources. Preventing them from flowing along a conductor, an even more higher series impedance is required. To be effective in LF range, large values of inductivity are required. Large inductors have a great amount of self capacity which in return again provides a conducting path for frequencies above LF. The cure in my case was to provide a private earth connection at the antenna (shorting out the noise voltages from shield to ground) and break up the conducing path from G to pG, leaving the leakage capacity in between both as the residual path for noise currents. best 73 de Gamal > -----Original Message----- > From: Costas Krallis [SMTP:sv1xv@eexi.gr] > Sent: Tuesday, January 23, 2001 2:44 PM > To: rsgb_lf_group@blacksheep.org > Subject: Re: LF: Mains Borne Noise > > At 11:44 23/01/2001 +0100, you wrote: > >>> Has anybody on the list got a "whole house" mains filter > >>> installed at their QTH? > > > > Not a "whole house" mains filter, but a radio room > > mains "filter". > > > > All main supply to my radio equipment is run via a > > single phase isolation transformer,... > > > The only problem with this approach is that in case of electrical > fault or lightning strike one of the two earths conductors is at > a high potential (voltage) in respect to the other.

The excursions usually seem to be around 0.09 Hz Well, I think I got them both this time. I have posted some details on my web page at cafe.rapidus.net/bill1/bbs.htm Scroll down to the bottom of the page and follow the link taking you to "NIAGARA Screenshots of LF Signals". Consistent with the above information, I saw two signals quite clearly but for short periods only. The first I presume to be Laurie. That signal was drifting upwards in frequency. It appears at 2019z and lasts for 23 minutes or so, disappearing at 2042z. The second is a straight vertical line - it appears later, starting at 2156z and ending after aboyut 31 minutes. This one I presume is Jim M0BMU. The NIAGARA settings I was using don't permit viewing the individual pulses, just let us see there is some signal there. The frequency of G3AQC's signal varied from 135922.22 thru 135922.33 - I'd say plus or minus 0.05 Hz is my calibration accuracy tonight. The frequency of M0BMU's signal was very stable and I make it 135923.96. I don't know why M0BMU showed up so much later than G3AQC and I don't know why M0BMU was so much weaker here. The images on my web page don't have the same colors as the actual screen. I'm still trying to figure out how to make a .BMP file that will reproduce the screen colors exactly when played back. My apologies for the image problems. I'll get it sorted eventually. 73 de Bill VE2IQ From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 2916 invoked from network); 25 Jan 2001 07:50:33 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by 10.226.25.101 with SMTP; 25 Jan 2001 07:50:33 -0000 Received: (qmail 4190 invoked from network); 25 Jan 2001 07:54:04 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 25 Jan 2001 07:54:04 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14Lh7Z-0003lC-00 for rsgb_lf_group-outgoing@blacksheep.org; Thu, 25 Jan 2001 07:47:05 +0000 Received: from kauha.saunalahti.fi ([195.197.53.227]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14Lh7Y-0003l7-00 for rsgb_lf_group@blacksheep.org; Thu, 25 Jan 2001 07:47:04 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from default (MCCXXXVIII.rdyn.saunalahti.fi [195.197.137.38]) by kauha.saunalahti.fi (8.10.1/8.10.1) with SMTP id f0P7lLC20868 for ; Thu, 25 Jan 2001 09:47:21 +0200 (EET) Message-ID: <3.0.6.32.20010125094708.0081e440@pop.saunalahti.fi> X-Sender: vaiski1@pop.saunalahti.fi (Unverified) X-Mailer: QUALCOMM Windows Eudora Light Version 3.0.6 (32) Date: Thu, 25 Jan 2001 09:47:08 +0200 To: rsgb_lf_group@blacksheep.org From: =?iso-8859-1?Q?V=E4in=F6_Lehtoranta?= Subject: Re: LF: Beacon signals tonight MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Signal report on Wednesday eve, 24 Jan 2001: MOBMU 135.92.., Fs average +4 dB(uV/m) G3AQC 135.92.., Fs average +1 dB(uV/m) Beat until 21 UTC stable 1.74 Hz, after 21 UTC about 1.6 Hz. -------------------------------------------- Signal report on Tuesday evening 23 Jan 2001: M0BMU 135.924, Fs average +5 dB(uV/m) G3AQC 135.922, Fs average +2 dB(uV/m) DL3FDO was transmitting tests abt 136.9 kHz: his Fs was around -1 dB(uV/m) ------------------------------------------- |---------------------------------------------------------| | V.K.Lehtoranta, OH2LX ¤ 60N33.6 024E58.7 KP20LN74 | | P.O.Box 50 ¤ Telephone: +358-9-4173965 | | FIN-05401, Jokela ¤ Telefax: +358-9-4173961 | | Finland ¤ email: vaiski@dlc.fi | |---------------------------------------------------------| From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 24270 invoked from network); 25 Jan 2001 04:12:40 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by 10.226.25.101 with SMTP; 25 Jan 2001 04:12:40 -0000 Received: (qmail 7662 invoked from network); 25 Jan 2001 04:16:09 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 25 Jan 2001 04:16:09 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14Ldif-0002t2-00 for rsgb_lf_group-outgoing@blacksheep.org; Thu, 25 Jan 2001 04:09:09 +0000 Received: from mta03.mail.au.uu.net ([203.2.192.83] helo=mta03.mail.mel.aone.net.au) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14Ldid-0002sx-00 for rsgb_lf_group@blacksheep.org; Thu, 25 Jan 2001 04:09:07 +0000 Received: from mstubbs ([63.60.255.72]) by mta03.mail.mel.aone.net.au with SMTP id <20010125040851.SEUG19418.mta03.mail.mel.aone.net.au@mstubbs> for ; Thu, 25 Jan 2001 15:08:51 +1100 Message-ID: <002001c08684$686aab00$48ff3c3f@mstubbs> From: "Michael Stubbs-Race" To: rsgb_lf_group@blacksheep.org Subject: LF: Reality Date: Thu, 25 Jan 2001 15:03:41 +1100 MIME-Version: 1.0 Content-Type: text/html; charset=windows-1252 X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.50.4522.1200 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Content-transfer-encoding: 8bit
Nicely put Steve.
 
I think one thing we overlook is that the powers-that-be really aren't interested in amateur radio, and have little on no experience of it. In fact to them it's just nuisance value.
 
Our future, as you correctly point out, is to look to the future with whatever technology offers, making choices appropriate for a particular band and conditions.

If you are not interested in this subject, please stop reading here or click on the delay button of your Email browser. Or explain to me why if it is completely "off-topic"... ( IMHO it's just a very little "off-topic" ;-) The stereo pilot tone used by FM broadcast stations is quite accurate for the large FM stations, and some may be useful for us as a cheap frequency reference, BUT (as Alberto 'PHD already thought): You have to find a station which produces an accurate frequency. In north western DL, I could not even find two with exactly the same pilot frequency. Just a few samples (without "absolute" accuracy, just to show the difference: WDR1: 19000.00 Hz (I used this as a pseudo-reference for the soundcard) WDR2: 19000.27 Hz (same company, other transmitter, 14 ppm off ?! ) WDR4: 19000.12 Hz (...) BFBS: 19000.07 Hz (British Forces Broadcasting Service) Maybe BFBS uses the the same stereo pilot tone as the BBC in London. WDR is one of the largest broadcasting companies in DL, but even they seem to differ from each other. (Compared to the accuracy of some well-equipped 'big guns' on LF, one may say the commercial broadcasters have lousy accuracy ). To verify that these differences are not propagation effects, I also compared some the TV line frequences (using a soundcard at 44100samp/sec, mixed down, decimated by 81, 64k FFT size, 0.008Hz resolution). All TV stations were received 'old style' via antenna. The TV line synch frequencies found this way (using the same "correction factor as above): ARD: 15625.18 Hz ZDF: 15625.19 Hz WDR: 15626.18 Hz RTL: 15626.20 Hz The difference between these signals are still above 1ppm (!?), but this may be based on propagation effects (It's not the measurement, I verified by switched the stations and watching the effect on the waterfall). Hope to meet you on the band in regular CW next weekend, even if it is our 10th QSO ! 73's Wolf (DL4YHF, DF0WD) From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 4359 invoked from network); 25 Jan 2001 00:06:58 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by excalibur.plus.net with SMTP; 25 Jan 2001 00:06:58 -0000 Received: (qmail 1051 invoked from network); 25 Jan 2001 00:01:14 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 25 Jan 2001 00:01:14 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14LZkX-0001dB-00 for rsgb_lf_group-outgoing@blacksheep.org; Wed, 24 Jan 2001 23:54:49 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from d06lmsgate-3.uk.ibm.com ([195.212.29.3]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14LZkW-0001d6-00 for rsgb_lf_group@blacksheep.org; Wed, 24 Jan 2001 23:54:48 +0000 Received: from d06relay01.portsmouth.uk.ibm.com (d06relay01.portsmouth.uk.ibm.com [9.166.84.147]) by d06lmsgate-3.uk.ibm.com (1.0.0) with ESMTP id XAA60796 for ; Wed, 24 Jan 2001 23:45:32 GMT Received: from usa.net (ss10.bld.socks.ibm.com [9.14.4.76] (may be forged)) by d06relay01.portsmouth.uk.ibm.com (8.8.8m3/NCO v4.95) with ESMTP id XAA245352 for ; Wed, 24 Jan 2001 23:54:04 GMT X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Message-ID: <3A6F6AC6.91FC9649@usa.net> Date: Thu, 25 Jan 2001 00:52:38 +0100 From: "Alberto di Bene" Organization: Undisclosed X-Mailer: Mozilla 4.76 [en] (Win95; U) X-Accept-Language: en MIME-Version: 1.0 To: "LF Mailing List" Subject: LF: Small drift in G3AQC signal ?

This ratio of normal CW to QRSS is about the same as for my own operating. Over the last six weels the sum total of my CW activitiy is GW4ALG, PA0BWL, F6CNI, IK5ZRP and EI0CF. The QRSS transmissions include two test transmissions for VE1ZZ and a two-way QSO with CT1DRP. At the moment I am making a QRSS test transmission on 135.9125kHz. A frequency check by anyone watching would be appreciated. As regards my QSO with CT1DRP on 136.4kHz. As I mentioned in a previous e-mail I had to modify the antenna because of a cracked insulator. The resulted in a reduction in antenna capacitance. I jury-rigged an inductor as a temporary measure but the setup would not tune above 137kHz. When a QSO with Brian was contemplated I found that he could not tune below 136.2kHz because of the Greek RTTY station, which is apparently quite strong at his QTH. I was monitoring the band using ARGO, and as there was no activity at all there I decided on a QRSS QSO in the CW sector. I did say at the time I would probably get 'flamed' on e-mail. For those who are anti-QRSS I would suggest they get a copy of ARGO. All you need is your computer with a sound card and a connector to the headphone socket of the receiver. It is simple and intuative to use and is excellent for CW only operators to see just what is going on on the band. You can also identify the QRSS operators and not have to rely on anyone else to provide identification. Just give it a try.

Occasionally I read it as ~.98 so the actual freq may be nearer ~.988 (ish) Laurie, unfortunately you are drifting somewhat. I've seen at least 0.15Hz shift. At 1945 it was 135922.34 and drifted to ~922.23 at 2020 where it remained until 2100z. Then you jumped to ~922.38, then ~2.33 at 2113z and drifted back to ~922.25 by 2220z. Then a similar kink later at 2240z after a break in transmission. The excursions usually seem to be around 0.09 Hz Measurement equipment is a RA1792 with its external reference input driven by a Caesium standard (with the Cs tube turned on for the first time in nearly a year) so RF accuracy is 'perfect' The sampling clock in the EVM56002 is the only frequency error and this is better than 1ppm so for a 1kHz tone max error is 0.001Hz. A great pity I can only read the frequency off the display to two decimal places ! Attached is AQCBMU.GIF (8KB size) showing 90 minutes of both of your signals in a 2.5Hz wide plot and the drift pattern on Laurie's signal. There is about 7dB difference in signal strength between both transmissions which considering the distances (Laurie is nearer and the stronger) means very similar ERPs.

I don't know about the situation elsewhere but here in VK the AVERAGE age of an Amateur is over 60. This indicates either there are a lot of us over 60 or there are next to no young people coming through the ranks. Increasing pressures on spectrum space for all sorts of wireless devices, both long-range, satellite and short-range will see corresponding increasing pressure on our allocations. The young are not motivated by traditional Amateur pursuits in sufficient numbers to inject youth into our hobby so it is in danger of slowly becoming an old boys' club even more than now. The arguments for present and new privileges (notice that the word is privileges - not rights) have been based on experimentation, relevant training and forming a pool of skills applicable to the current technology environment. For example, our VK LF submission to our governing authority makes large mention of experimentation (no mention of DXCC, QSL count, etc) as even the old salts here realise that this is the best approach for success in the present regulatory environment. The submission does make a strong point for experimentation but specifically asks that operation be NOT restricted to CW "to allow experimentation in a wider variety of communication techniques..". I know in my case when applying for my Scientific Licence for operating on LF here, I had to submit a technical reason for wanting to operate on that band. That submission included details of narrowband experiments. If I had just submitted it with saying I just wanted to have a CW QSO then I would have had a snowball's hope in that hot place of succeeding. The world is changing and everything is increasingly being subjected to justification. Frankly I cannot see how we have maintained our privileges as we have in the present climate. We are up against strong commercial pressures for spectrum space and pushing the CW, QSL card, DXCC barrow to the detriment of more contemporary pursuits will not only not help us, it will hinder us. I sympathise with those feeling the pressure of the modern age as they grow older. This is because I too feel this pressure (although in Amateur terms I am a spring chicken at 51), but in my case I have decided it is of no use longing for the "good ol' days". It is a sad fact of life that CW is on life support as it is abandoned by authorities around the world. Quoting single instances to the contrary will not change this. I respectfully submit the following code of practice for us who are interested in the Amateur hobby surviving in the new millennium. General: Eliminate all negative aspects of the exchanges within the Amateur fraternity as much as possible. Encourage new ideas, embrace technological change and generally show we are worthy of a place in the increasingly competitive environment in which we seek to operate our hobby. Non-CW Types: Continue to push for new techniques, new ways, and let your imagination and the current regulations in your location be your limit, not some-one else's limited vision of the world. CW-Types: Try a new tack of keeping your particular interest alive. Try a friendly, supportive approach instead of the Neanderthal "hit them over the head with a club and drag them back to the cave" approach. This aggressive approach is very effective in hiding the fun aspects of CW operation. In fact I really believe that some of the loudest and more obnoxious CW advocates are in reality anti-CW for the damage they do to the CW case. As for the Trans-Atlantic challenge. I am always for a challenge. I guess that makes me a "young" 51-year old. My 80-year old MIL has just started learning about computers and we have connected her to the internet. It is a struggle for her sometimes, but she persists and is loving it. That makes her a "young" 80-year old. Without a challenge to stimulate you, you are just marking time. I echo a previous poster who remarked that he would not have gone for his Amateur ticket to just engage in QSOs or to be limited to one mode. There have been (and will be in the future) instances where some-one has inadvertently transgressed into the wrong part of the "gentleman's agreement" band space. This has been apologised for and to suggest that it was deliberate or a sign of incompetence is, in itself, a sad sign of senile paranoia. It is amusing that some of the least gentlemanly communicators are demanding the strictest adherence to a "gentleman's agreement". Here endeth the lesson... 73s Steve Olney (VK2ZTO/AXSO - QF56IK : Lat -33 34 07, Long +150 44 40) ============================================= HomePage URLs: http://www.qsl.net/vk2zto http://www.zeta.org.au/~ollaneg Containing:- ULF, ELF, VLF & LF Experimentation InfraSonic Experimentation Laser Comms DX Amateur Radio Astronomy ============================================= From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 18149 invoked from network); 24 Jan 2001 20:22:46 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by 10.226.25.101 with SMTP; 24 Jan 2001 20:22:46 -0000 Received: (qmail 27089 invoked from network); 24 Jan 2001 20:26:17 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 24 Jan 2001 20:26:17 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14LWPb-0000hl-00 for rsgb_lf_group-outgoing@blacksheep.org; Wed, 24 Jan 2001 20:20:59 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from gadolinium.btinternet.com ([194.73.73.111]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14LWPY-0000hg-00 for rsgb_lf_group@blacksheep.org; Wed, 24 Jan 2001 20:20:56 +0000 Received: from [213.1.172.62] (helo=host213-1-172-62.btinternet.com) by gadolinium.btinternet.com with smtp (Exim 3.03 #83) id 14LWPL-0001nv-00 for rsgb_lf_group@blacksheep.org; Wed, 24 Jan 2001 20:20:44 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 From: "Nick" To: rsgb_lf_group@blacksheep.org Subject: Re: LF: Re: More normal CW Date: Wed, 24 Jan 2001 20:19:37 +0000 Message-ID: References: <6888363.980343554953.JavaMail.imail@chilly.excite.com> In-reply-to: <6888363.980343554953.JavaMail.imail@chilly.excite.com> X-Mailer: Forte Agent 1.8/32.548 MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 8bit Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: On Wed, 24 Jan 2001 05:39:07 -0800 (PST), you wrote: > but I would >appreciate advice on better waterproofing.

I believe a high stability oscillator is > available for the 706. I am also using the old IC706 (at DF0WD) and also got some problems with its stability (a matter of some Hertz at 10.137 MHz). The thing gets much worse if you use it for transmitting. I did some test with very slow PSK (and other modes) some weeks ago, and noticed some dramatic "curves" in the loran lines after switching from TX to RX (I use the 706 to drive a transverter). There is indeed a temperature compensated oscillator availabe, it is a small SMD part called "CR-502". It is specified for stability of +- 0.5ppm in the temperature range from -30°C to +60°C (so it should be ok). The frequency of this oscillator is exactly 30 MHz, so it can be "tied" to any 10MHz reference because it has a frequency control input (I already drilled a hole for a BNC connector into the housing for that purpose). Ironically, I am waiting for two weeks for that part now. I will keep you informed if I know more about its performance if you like. 73's Wolf.

I think we all see the drop in noise level before dawn over here. Wonder where the "Eastern" QRN originates.

>I saw a huge increase in signal strength from DCF39 between >1930 and 2030 last night.

That would correspond with the times I was operating normal CW.

In order to test VE2IQ's proposal, I will try to transmit beacon signals earlier tonight, hopefully from about 1930 for at least some hours. I don't think I can face another full night's operation so soon.... frequency and signal will be the same, unless anyone has a better idea.

I hope Bill's trace does turn out to be G3AQC - however, there are always lots of traces on LF, so it is important to identify if it truly is Laurie. Bill does not mention the resolution he was using was sufficiently wide to see Laurie's 30s dots. Perhaps if Laurie could put some gaps in his beacon sig nal, it would be more distinctive for ID purposes in very narrow bandwidths.

Let's give it another go, then!

Cheers, Jim Moritz

Same here, a 2.2mH coil hanging at 14m height and a 0.8mH coil on a plastic box about 0.5m above ground. Both have no protection against wind, rain, hail, snow etc ... and survive for about 3 years now (keep fingers crossed). No problems with flashovers or tuning, thanks to the large loss resistance (abt. 120 Ohm in winter, abt 140 Ohm in summer). one of the few advantages of all the lossy green capacitors (brand : birch and oak) surrounding my antenna. 73, Rik ON7YD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 15232 invoked from network); 24 Jan 2001 16:10:01 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by excalibur.plus.net with SMTP; 24 Jan 2001 16:10:01 -0000 Received: (qmail 5503 invoked from network); 24 Jan 2001 16:04:16 -0000 Content-Transfer-Encoding: 8bit Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 24 Jan 2001 16:04:16 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14LSF6-0007qH-00 for rsgb_lf_group-outgoing@blacksheep.org; Wed, 24 Jan 2001 15:53:52 +0000 Received: from indyweb.cgocable.ca ([205.151.69.200]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14LSF5-0007qC-00 for rsgb_lf_group@blacksheep.org; Wed, 24 Jan 2001 15:53:51 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from 220-142.lr.cgocable.ca (220-142.lr.cgocable.ca [24.226.220.142]) by indyweb.cgocable.ca (8.9.3 (MessagingDirect 1.0.4)/8.9.3) with SMTP id KAA748315 for ; Wed, 24 Jan 2001 10:53:37 -0500 (EST) Message-ID: <200101241553.KAA748315@indyweb.cgocable.ca> X-Sender: bill1@cgocable.ca X-Mailer: Windows Eudora Light Version 1.5.2 MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii; format=flowed Date: Wed, 24 Jan 2001 10:52:09 -0500 To: rsgb_lf_group@blacksheep.org From: "Bill de Carle" Subject: LF: G3AQC seen last night in Quebec Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: At 03:04 PM 1/24/01 +0000, Jim M0BNU wrote: >Dear LF group, > >I transmitted beacon sigs last night from 2145 until 0630.

I measured him on 135922.44 early in the session, then he faded out. I have an image of this - I'll post it on my web page later. The other line which also started out well but faded at about the same rate was on 135925.02 so I guess that wasn't you Jim. >Earlier, I found propagation conditions seemed unusual.

I saw a huge increase in signal strength from DCF39 between 1930 and 2030 last night. I posted a message to this reflector about it a few minutes ago. There was a small GIF (less than 10K) attached showing just how big the signal got for a short time. That may have been due to the flare, no? If that was the case I'll have to modify my suggested time for transmissions from Europe to here to make it coincide with our local dusk. Thanks for the accurate info on G3AQC's frequency. That's as good as a confirmation for me because I'm quite sure the line I saw was on 135922.44 and there was nothing else around him. Congratulations Laurie!

First of all there was a great deal of static and it lasted pretty much through the evening, so conditions were poor here for receiving weak signals from across the pond. I did notice two faint lines which I thought might be Laurie and Jim - but hard to confirm this because I don't know their exact frequencies. The lines both appeared early in the recording session then faded away as the evening wore on. Yesterday afternoon before I started monitoring 135923 I left the machine running for a while on 138830 to see how DCF39 was doing. Their signal peaked strongly for about an hour between 1930 and 2030 - that's mid afternoon here. There is a small (10K) GIF attached to this message which shows how strongly DCF39 came up out of the noise here yesterday afternoon. If it gets through the reflector the filename is DCF39.GIF. It looks like the best time to receive signals from North America is around local dawn in Europe. That's when the path is still in darkness but it's already light towards the East, so noise from that direction is reduced. On the other hand, the best time for North American stations to receive European transmissions seems to be just before darkness in our time zone - when most of the path is already in darkness but we still have low noise levels because we're not yet receiving much to the west of us. With this in mind, to complete a 2-way QSO would it not be prudent to have the European end transmit from say 1930 to 2030 and have the Canadian end transmit from 0630 to 0730 UTC? I don't know if there is any limit for how much time can elapse between transmissions at either end to qualify as a bona fide 2-way QSO? I would hope some allowance would be made for this unusual band. I'd say that as long as call signs and signal reports are exchanged on the same day it should qualify as a 2-way, hi! 73 de Bill VE2IQ --------------070704030003090302020104 Content-Type: image/gif;

LF group, I transmitted beacon sigs last night from 2145 until 0630. The signal was roughly 110sec dashes and spaces, with a 400sec space (containing a 60s CW ID) every 5th dash. Thanks for the signal reports; I hope OH2LX has the frequencies swapped round, since my frequency should have been 135.924kHz +/- 0.1Hz at most, unless something went dreadfully wrong. I checked G3AQC as being about 1.6Hz down on me. Whose was the 3rd signal I saw in the early morning? Earlier, I found propagation conditions seemed unusual. I had QSO's with G6RO, DL3FDO, and EI0CF. Ron's signal seemed normal, but the others were subject to quite rapid (a few minutes) QSB, and both getting very strong at times. I wonder if anyone in North America observed sigs from DCF39 or similar? Would this be connected with solar events? A thought that occurred whilst trying to keep the antenna in tune during last night's wind was - would the phase shifts caused by the antenna impedance changing affect reception in very narrow bandwidths? It would not affect the mean frequency of course, but I estimated from the scope screen that the phase shift could change up to 30degrees in a few seconds, which I reckon would amount to a change in instantaneous frequency of 10's of millihertz. I would agree with G3AQC about condensation; I find it necessary to open up my loading coil shelter to let it dry inside whenever the weather is fine; I also have installed a cheap fan heater inside it for when the weather is not so fine. With regard to the other topics raised, as a relative newcomer to amateur radio, I quite enjoy a CW QSO (although my arm aches after a while!), and find that excellent results can be achieved considering the simplicity of the mode. It does enable you to achieve something from very modest beginnings. But I would not have bothered to get my amateur ticket just to make CW QSOs - there are so many more things to try, and challenges to meet in radio. My non-amateur contempories find it faintly ridiculous that anyone would bother using CW, or SSB or packet for that matter; in a world with more communications than we know what to do with, being able to communicate with fellow amateurs using radio is not much of a draw. I am told that I would do much better to ring them on their mobile phone, or send them an E-mail. However, the nature of radio itself is much more interesting; exploding PAs and trying to cross the Atlantic using bizzare communications modes is much more likely to attract the interests of newcomers. Obviously, diversity and balance is needed to sustain amateur radio, LF or otherwise.

Standard PVC tape has a dielectric constant (Er) about the same as the polyethylene insulator in the cable. So as your joint must have increased the diameter of the inner conductor, its Zo will have reduced and given you a small section of mismatched line at 50cm (cable) wavelength. However, as the foamed is part air the resultant lower Er would partly compensate for the increased conductor diameter. Mind you, PVC is a lot more lossy than polyethylene so still some element of real loss in this.

It appeared at about 2200, peaked at 0130 and 0830 and vanished at 0930 all in utc.The pictures are on my web pages. A pity that the call sign did not coincide with either of the peak periods. My thanks to the Argo authors, this was the first time of use. To add to the current discussion, I find it quite strange there is an argument at all. I doubt if there is any activity within a radius of 500Km and not too much within 1000Km. The only times I have seen a possible signal on wide band monitoring was David G0MRF on two occasions and only identified by timing and frequency. At the moment you could call CQ CT until the cows come home, at any speed, in any mode but unless I know the frequency and time an answer would seem unlikely. This will change and if I am still here will probably regret the change----we are all conservatives at heart. 73, Brian 73 Brian CT1DRP IN51QD 41 09 58N 08 39 11W http://homepage.esoterica.pt/~brian From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 4232 invoked from network); 24 Jan 2001 11:18:37 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by extortion.plus.net with SMTP; 24 Jan 2001 11:18:37 -0000 Received: (qmail 28809 invoked from network); 24 Jan 2001 11:21:24 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 24 Jan 2001 11:21:24 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14LNpE-0006X8-00 for rsgb_lf_group-outgoing@blacksheep.org; Wed, 24 Jan 2001 11:10:52 +0000 Received: from d06lmsgate-3.uk.ibm.com ([195.212.29.3]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14LNp9-0006X3-00 for rsgb_lf_group@blacksheep.org; Wed, 24 Jan 2001 11:10:51 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from d06relay02.portsmouth.uk.ibm.com (d06relay02.portsmouth.uk.ibm.com [9.166.84.148]) by d06lmsgate-3.uk.ibm.com (1.0.0) with ESMTP id LAA179174 for ; Wed, 24 Jan 2001 11:01:16 GMT Received: from usa.net (ss6.bld.socks.ibm.com [9.14.4.71]) by d06relay02.portsmouth.uk.ibm.com (8.8.8m3/NCO v4.95) with ESMTP id LAA44222 for ; Wed, 24 Jan 2001 11:09:25 GMT X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Message-ID: <3A6EB78F.F2D7FDAD@usa.net> Date: Wed, 24 Jan 2001 12:07:59 +0100 From: "Alberto di Bene" Organization: Undisclosed X-Mailer: Mozilla 4.76 [en] (Win95; U) X-Accept-Language: en MIME-Version: 1.0 To: rsgb_lf_group@blacksheep.org Subject: Re: LF: Beacon signals tonight References: <3.0.6.32.20010124121601.0081f100@pop.saunalahti.fi> Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-MIME-Autoconverted: from 8bit to quoted-printable by d06lmsgate-3.uk.ibm.com id LAA179174 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Väinö Lehtoranta wrote: > [snip] > M0BMU 135.922, Fs average +2 dB(uV/m) > G3ACQ 135.924, Fs average +5 dB(uV/m) > [snip] Väinö, are you sure to not have them reversed ?

I agree that CW activity has decreased over the last months but I do not thing that QRSS is to blame for it. Apart from one case of unintentional QRM (where apologies were given and accepted) there has been one weekend that many of us were looking for QRSS signals on 136.5kHz. All QRSS transmitting actvities (in Europe) have either been below 136.0 or above 137.6kHz. For the last years I keep note of the stations and hear, about a year ago I had about 20 stations in CW and about 5 stations in QRSS over a weekend. Now I have about 10 stations in CW and still about 5 stations in QRSS. What I have also noticed is that the activity shifted from the UK toward the continent, there is a lot of activity from PA, DL and F now. One of the most facinating aspects of amateur radio is 'breaking frontiers' and that is excatly what the QRSS transatlantic tests are all about. But as every new mode QRSS has to overcome some opposition. When reading the 'letters from readers' in old ham magazines you will find the same reactions in the AM versus SSB controverse in the early sixties or the AM versus FM controverse on 2 meter a decade later. I would regret it if we would stop the QRSS transatlantic tests now and seriously doubt that this would increase the CW activity. I see no reason why QRSS and CW can not co-exist. 73, Rik ON7YD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 7676 invoked from network); 24 Jan 2001 09:56:54 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by extortion.plus.net with SMTP; 24 Jan 2001 09:56:54 -0000 Received: (qmail 4796 invoked from network); 24 Jan 2001 09:59:42 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 24 Jan 2001 09:59:42 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14LMbg-00068m-00 for rsgb_lf_group-outgoing@blacksheep.org; Wed, 24 Jan 2001 09:52:48 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from d06lmsgate-2.uk.ibm.com ([195.212.29.2]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14LMbf-00068a-00 for rsgb_lf_group@blacksheep.org; Wed, 24 Jan 2001 09:52:47 +0000 Received: from d06relay02.portsmouth.uk.ibm.com (d06relay02.portsmouth.uk.ibm.com [9.166.84.148]) by d06lmsgate-2.uk.ibm.com (1.0.0) with ESMTP id JAA31644 for ; Wed, 24 Jan 2001 09:37:33 GMT Received: from usa.net (ss6.bld.socks.ibm.com [9.14.4.71]) by d06relay02.portsmouth.uk.ibm.com (8.8.8m3/NCO v4.95) with ESMTP id JAA287938 for ; Wed, 24 Jan 2001 09:51:47 GMT X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Message-ID: <3A6EA560.8A9E2CCB@usa.net> Date: Wed, 24 Jan 2001 10:50:24 +0100 From: "Alberto di Bene" Organization: Undisclosed X-Mailer: Mozilla 4.76 [en] (Win95; U) X-Accept-Language: en MIME-Version: 1.0 To: rsgb_lf_group@blacksheep.org Subject: Re: LF: Beacon signals tonight References: <27783.200101231704@gemini> <14LDNp-0iKRpQC@fwd03.sul.t-online.com> Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 8bit Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Same here in Italy, JN45SL.

Firstly, the frequency stability - presumably of my IC-706 Mk1 - was not good enough for the 30s dot setting. After a long warm-up period, it settled down to a ragged line that wandered all over the screen. My son opened a window in the next room to the shack and the Loran lines moved off the screen completely! Does anyone else have experience of this? I believe a high stability oscillator is available for the 706. Secondly, I used the screen capture facility for the first time and has several good images, then lots and lots of pictures of my screen saver! Ooops.

There is a desperate need for more normal CW QSOs on the band if we are to encourage new operators on the band - as far as the UK is concerned we have seen very few of these in recent months. Perhaps it is my own fault that I have yet to have a 136 QSO this year, but lack of activity must form part of the reason. It should also be mentioned that the content of this reflector is also part of the same problem. I remember the time when John G4GVC was very active (come back John!) when there were many mails about what others had been doing on the band - now it is full of esoteric mode discussion and even more mails which get directly deleted. I know many of you are into these modes, but many of the new blood we need may well be disillusioned if they come here looking for general guidance. As for band plans, all I would say is that there is no excuse for operating QRSS for an inter European QSO during Sunday daytime in the most active part of the normal CW segment. 73s Dave G3YMC dsergeant@btinternet.com dsergeant@iee.org http://www.btinternet.com/~dsergeant From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 28328 invoked from network); 24 Jan 2001 02:20:27 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by 10.226.25.101 with SMTP; 24 Jan 2001 02:20:27 -0000 Received: (qmail 13808 invoked from network); 24 Jan 2001 02:23:56 -0000 Content-Transfer-Encoding: 8bit Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 24 Jan 2001 02:23:56 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14LFWR-0004GC-00 for rsgb_lf_group-outgoing@blacksheep.org; Wed, 24 Jan 2001 02:18:55 +0000 Received: from indyweb.cgocable.ca ([205.151.69.200]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14LFWP-0004G7-00 for rsgb_lf_group@blacksheep.org; Wed, 24 Jan 2001 02:18:53 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from 220-163.lr.cgocable.ca (220-163.lr.cgocable.ca [24.226.220.163]) by indyweb.cgocable.ca (8.9.3 (MessagingDirect 1.0.4)/8.9.3) with SMTP id VAA487929 for ; Tue, 23 Jan 2001 21:18:39 -0500 (EST) Message-ID: <200101240218.VAA487929@indyweb.cgocable.ca> X-Sender: bill1@cgocable.ca X-Mailer: Windows Eudora Light Version 1.5.2 MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii; format=flowed Date: Tue, 23 Jan 2001 21:17:11 -0500 To: rsgb_lf_group@blacksheep.org From: "Bill de Carle" Subject: Re: LF: Beacon signals tonight Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: At 01:01 AM 1/24/01 +0100, Uwe wrote: >James Moritz schrieb: >> Dear LF Group, >> >> So that G3AQC does not feel lonely, I will also run a beacon signal >> tonight on 135.924kHz. 1Hz seperation is quite small; but anything >> that stands much chance of seeing either signal will easily >> seperate them too.

At the settings I'm using the frequency resolution is good (0.016 Hz) but each pixel covers some 62.44 seconds of time so I don't have any chance of seeing any actual keying; I figure I'm lucky just to detect their presence, hi! It would help a great deal if someone over there who is able to receive these signals at good strength could measure their exact frequencies so I can pin them down at this end. If you can't measure absolute frequency, at least it should be possible to measure the difference between the two signals if you can see them both on the screen at the same time. Thanks in advance.

I used to use plastic sticky tape (any colour) to insulate between inner and outer of RG-213 coax cable where I'd joined it (typical amateur using odd lengths!) . Then I found I was losing 1-2 dB at each joint at 70 cms so abandoned it and used foamed polyethylene instead which is fine.

It seems that 'factor' still means the same these days, at least according to a Web dictionary which gives Factor as 'One of two or more quantities that divide a given quantity without remainder'. So 4 and 6 also qualify. It is a pity that the people back in history who were responsible for the decimal system did not have twelve fingers. Then we would have the superior scale of 12 for mathematics as well as for weights and measures. There is nothing magic about 10. It is just that we were all brainwashed to think so! 73 Bernard G3SMW From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 10227 invoked from network); 23 Jan 2001 20:48:44 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by excalibur.plus.net with SMTP; 23 Jan 2001 20:48:44 -0000 Received: (qmail 21491 invoked from network); 23 Jan 2001 20:43:00 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 23 Jan 2001 20:43:00 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14LAAQ-0002jB-00 for rsgb_lf_group-outgoing@blacksheep.org; Tue, 23 Jan 2001 20:35:50 +0000 Received: from latimer.mail.uk.easynet.net ([195.40.1.40]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14LAAP-0002j6-00 for rsgb_lf_group@blacksheep.org; Tue, 23 Jan 2001 20:35:49 +0000 Received: from ericadodd (tnt-6-240.easynet.co.uk [195.40.201.240]) by latimer.mail.uk.easynet.net (Postfix) with SMTP id 681FE536D0 for ; Tue, 23 Jan 2001 20:35:35 +0000 (GMT) Message-ID: <000801c0857c$4e566e60$f0c928c3@ericadodd> From: "g3ldo" To: rsgb_lf_group@blacksheep.org References: <200101211244_MC2-C27B-A908@compuserve.com> <3.0.1.16.20010123103247.2ca7529e@mail.cc.kuleuven.ac.be> Subject: Re: LF: Re: vector potential Date: Tue, 23 Jan 2001 20:35:58 -0000 MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.50.4522.1200 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Hi Rik, > I did a little test on saturday afternoon : > I did put the lower part of the loading coil (that is normally in > horizontal position) vertical (directly under the wire). > I did measure the antenna current and the signal strength of DCF39, in both > cases not the slightest difference. Interesting. Some time ago, while operating from Amberley Museum, we had a Tesla coil group giving a demonstration. It was though that this would cause interference with my operation, located about 1km away. It did not. Out of curiosity I took my mobile LF equipment and parked close (100m) to where the Tesla group were demonstrating. I enquired as to what frequency they were operating on. It seemed to depend on the size of the coil - small coils and small sparks used higher frequencies, around 200kHz. The very big coils operated on lower frequencies - around 70kHz - as you might expect. I set up the LF receiver with a short length of wire so that I could hear the stronger commercial stations. When the Tesla coils were fired up tuned around and heard - nothing! This surprised me. I expected, with that degree of power being used for the receiver to be overwhelmed. The Tesla coils were close wound with an annular metal capacity top from where the sparks were induced with an earthed wand. Now Toni, HB9ASB, used a coil as an antenna on LF, see page 58 of the LF Experimenter's book. This type of coil is known as the Normal Mode Helix. This type of antenna is incorporated into Rubber Duck antennas used with VHF/UHF handhelds. A mathematical analysis of this antenna is given, in the discussion of different types of antennas, in Corum's torodial antenna patent application. At the end of this analysis is the following: "There is an alternative way to derive Equation 1. (from the analysis just described), which proceeds from the introduction of a fictitious conceptional aid. This very useful tool is a great assistance to performing field computations for helices and solenoids. Kraus has shown that a loop of electric current, i.e., electric charges flowing around the circumference of the loop produces the same radiation fields as those of a flow of a fictitious magnetic charges moving up and down the axis of the loop. The fields external to a helically wound solenoid can be found by assuming a flow of electric charges around the helix, or by assuming a flow of magnetic charges moving along the axis of the solenoid. The latter computation is much simpler to perform analytically than the former". The word vector potential is not used but in a formula illustrating this we have. AR = (|E subscript theta| / |E subscript phi|) [The = sign has a delta sign over it - whatever that means.] The purpose of quoting this formula is not to try to blind you with science but to show that our mysterious A has popped up again.

Surely one critic is enough, if not too many. I don't hear all that much activity on the band most days anyway. There is surely room for all interests. Bob hasn't been on the band recently, but he was constantly calling CQ and rarely replied to. If the 1W QRSS guys are treading on the toes of others, then lets's find a friendly solution. It is not my job to apologise for others, but Peter did apologise as I recall. I for one am enjoying LF. I don't transmit much it's true, but don't have the resources that some of the others have, so content myself most of the time to just listening. Most days there is plenty of normal CW to be heard. Today I heard several German stations and also EI0CF back on the band. LF is a great place to learn and improve one's CW skills. Just listening is great fun. Please let us show tolerance for one another and enjoy ourselves at the same time. All modes are welcome in my book, provided we respect one another.

I think that the golden days of LF are finished, and, today, I would not advise anyone to waste their time building an LF station. A couple of years ago we could all make QSOs on LF using simple CW equipment - knowing that there were plenty of courteous operators on the band - all ready to give us a report and to provide encouragement. But the arrival of demon QRSS operators such as G3LDO has changed all that. These days, CW operators have to do their best between S9 + 20 dB QRSS signals sent by operators who have little or no regard for other band users. With so much QRSS now taking place within the normal CW segment of the band, 136 kHz is no longer a suitable band for those wishing to make QSOs with simple equipment. Today's QRSS operators are removing the opportunities for experimentation that they themselves were enjoying just a couple of years ago. I am not surprised that newcomers get fed up with listening to strange, intermittent carriers on LF. > I accept that to bridge the Atlantic Ocean is much more > challenging than a normal CW QSO within Europe but nevertheless > I would like to hear some more traditional activity on Saturday > and Sunday morning, as it was a year or more ago. CW operators might return to 136 kHz if they knew that there was a part of the band where they were not going to be QRMed by lid operators. But, at the moment, this is looking unlikely: I'm afraid that the unfortunate actions of our very own LF mentor has set the scene for others throughout Europe to follow. In the past, I have always been keen to promote 136 kHz via my web site. In the light of recent events, I feel compelled to update my web pages to provide a more accurate picture of what it's like to operate on LF from the UK these days.

This 11.024XXX divided by 2 is the "corrected clock value" that JVComm32 needs to print a straight vertical line when in HF-FAX mode , 60 lines per minute. It's not some measured reference value. The procedure was: - JVcomm using 11025 as default sampling rate and 60LPM mode. - WWV or GPS 1pps pulse to receiver. - Some minutes later I had a slanted line, which reveals the sound card clock inaccuracy. - Applying the "slant correction", software pop-up an info "I'll set the clock value as 11.024XXX/2". That's it. W95SSTV needed offset at the same "direction". But this software doesn't show the adopted value. Other numbers for the same "800Hz" tone: = Analyzer2000 measured 796,4Hz. = Argo measured 802,25 Hz - don't remember the decimal portion = Freq Counter measured 798.8 <> 801.6 - alternating = Spectran 127 , 8KHz sampling rate, needed -6.7Hz offset to show 800.0 Hz = PSK31 for SB16 gave -5 degree (AFC off) - (6 degree = 1 hz?) I have K6STI DSP-Blaster with its I/Q vector display, SbFFT1.2 from KW5Q, Spectrum for EVM (G3PLX). I'll do some measurements tonight to see what I got.

I don't think there are any Loran lines on this frequency - if there are, or any other problems please let me know. I hope to start around 2200, and will be sending the 90s dashes signal I described before, together with occasional CW IDs. I will carry on until I get thoroughly fed up!!

There are several very strong ultra-stable signals visible more or less throughout the night on either side of you (Loran C?) - and a few weak signals noted, particularly on 135920.88, 135920.46 and 135920.55 - but your frequency seems to be completely in the clear.

Keen subscribers to this group may remember that my cable-tie insulators failed last weekend, and that I assumed this was due to them becoming brittle in the sub-zero temperatures. I took the mast down on Sunday and found that the insulators had been sparking and had burnt through. Since they had worked fine up to then, I assume this was because they were coated in ice and snow. I have replaced them with 100mm lengths of 5mm thick perspex (that's Plexiglass for those divided by our common language) cut from a large piece that I picked up at the Puckeridge LF site. I did wonder whether the cable ties had been sparking before they became iced up, and expected to see an increase in current at the feed point caused by an increased voltage at the far end. However, there was no change so cable ties make perfectly good insulators when not icy. I have taken some photographs of the dead insulators, and will post on my web site soon.

At this moment I haven't coded for SB16-type sound cards because the one I'm using in my laptop is an ES688. I'll put the command into NIAGARA today to output the same (.wjs) file format Andy uses. Is that OK with you Andy? With NIAGARA using its 1000x magnification mode you get an effective sampling rate of 8.2 samples per second - and bin widths similar to what we've been playing with.

Again, NIAGARA now has the capability to change the threshold settings and re-compute the entire screen so you don't have to wait another 6 hours for another screenful to come in before you see if you've chosen the right setting, hi! And it can process pre-recorded raw audio. I have several programs here that can save raw audio, you're welcome to try any of them.

I am using NIAGARA with a sound card sampling rate of 8200 s/s and a magnification factor of 1000.

I am a very poor one-finger typist and I occasionally miss a key. I miss-hit the key for 'p' in the word 'deprived' in this paragraph. It appears as 'derived' which has almost the opposite meaning and you probably interpreted it accordingly!. There is NO magnetic field outside an infinitely long solenoid and neglible magnetic field outside a reasonably long thin solenoid such as that used in the mobile antennas that look like fishing rods with a spiral winding along their length but which are very reasonable radiators. In the case that you cite of the electron beam in a magnetic field there is indeed a magnetic field, so I regret that the example that you cite is not relevant. Incidentally, in the same paragraph, the name of Bohm's co-author should have been Aharanov - another slip of mine. >And with good reason.

This is simply a matter of historical usage, a better term might be 'electromagnetic vector potential' - to avoid confusion with the vector potentials used in fluid mechanics. I have just turned up a quote from Robert Feynman: ".... the effects depend only on how much the field A changes from point to point and therefore on the derivativesof A and not on A itself. Nevertheless the vector A (together with the scalar potential that goes with it) appears to give the most direct descriptionof the physics. This becomes more and more apparent the more deeply we go into quantum theory. In the general theory of quantum electrodynamics, one takes the vector and scalar potentials as the fundamental quantities in a set of equations that replace the Maxwell equations: E and B are slowly disappearing from the modern expression of physical laws: they are being replaced by A and phi. " The fundamental laws of the Universe do not change with size. Whether one is dealing with photons in the gamma ray spectrum or in the radio spectrum, where a photon at 73 kHz is about 4 km long, one is dealing with the same fundamental phenomena and the same fundamental laws are obeyed. My only personal comment on Feynman's statement is that I believe that we will find that the scalar potential, phi, which is fundamentally associated with electrons and other charged particles, will be shown to be the trapped vector potential coherently spinning round within each particle and therefore appearing as though it is a scalar potential emanating from a point charge. 73, Roger. >the chaff. And with good reason. In our search for the Holy Grail of efficient electrically small antennas we do consider many strange devices - some invoking Maxwells equations to prove viability.

The original reason for the sampling rate in the 44 kHz region is that video tape recorders were used widely in early digital audio experiments long before the CD. There was usually three samples/channel in every video line between the synch pulses. With 525 lines @ 60 Hz interlaced, that would give 47250 samples/channel. However, there is a large number of lines used for vertical synch, thus, the samples had to be averaged over a single field, giving rates such as 44056 Hz or 44100 Hz. In order to be able to store digital audio on both 525@60 Hz and 625@50 Hz video recorders, the sampling rate have to contain the 2, 2, 3, 5 and 5 primes. Thus, each video field would contain 735 resp. 882 samples and with 3 samples/line, 245 resp. 294 active lines/field or 490 resp. 588 lines/frame are used, the rest was taking by the vertical blanking.

At 30sec per dot, with 137790 at the centre Argo shows approx 137785.3 to 137791.9. The only Loran line in this range that might be seen in the UK is at 137787.8473 Hz. In Canada I believe that the only Loran lines in this range are at: 137785.419532 (Newfoundland chain), 137790.893761 Canadian Eastern Seaboard chain, and 137786.144578, 137791.164659 of the North East US chain.

Obviously any 'resistive' losses with generate heat I once had the idea of making my mast-head loading coil look better by waterproofing it with some of the sealant you squirt between the bath and the wall in a bathroom. It comes in several colours and I tested the brown one in a microwave oven. I am pleased that I did as it became VERY hot. I could have spoiled a long length of Litz wire by using this material. I am back to using black plastic sticky tape (a reel of this stays cold in the microwave oven - though the cardboard former gets warm).

You will need the hardware, something like a 56002EVM that I use to do all the high speed ( ! ) DSP Sorry ! Unless someone can be persuaded to write something similar for the soundcard. If 8 bit sampling is good enough - it usually is if no strong signals appear in the IF passband that exceed the noise by more than 30dB - one of the sampling options on my PIC based interface serial A/D will I/Q sample a 750 - 1250 bandwidth centred on 1kHz and a PC can do the rest. A commercial version is available from HF-Instruments WWW.HF-INST.CO.UK Saving raw data overcomes the problems of setting wrong colour thresholds, FFT sizes and the like and means you can go back and replot, changing any parameter at will. Saving two 16 bit numbers per sample means 24 hours recording at 3.9Hz (8000Hz / 2048) generates a file of just 1.35 Meg.

One thing of interest though, the loop structure seen on your photo taken at 04:47 is also present on mine (I took pics every 30 mins), so the source is roughly equidistant and therefore I guess remote.

The only problem with this approach is that in case of electrical fault or lightning strike one of the two earths conductors is at a high potential (voltage) in respect to the other. As the earth conductors are connected also to various metal objects (water pipes, equipment chassis etc) this situation can easily cause electrical shock or fire. A few years ago somebody tried a similar isolation system but conencted together the two earth conductors with an inductor made of thick electrical wire on a ferrite toroid. The coil had very small reactance at power frequency (50/60 Hz) but blocked conducted noise at radio frequencies.

The SNR was quite good in the period before dawn. Good signals were observed at 0330-0400, 0450-0510, 0545-0720. The last period was the best, as noted in the other reports. I found the noise level was pretty low throught the night. As far as mains noise goes, I did once try some experiments with decoupling the house mains supply. On the whole, this was unsuccessful, some combinations of filtering and grounding actually made the noise worse. I concluded that the main problem was that it is very hard to get a decent ground connection, and that decoupling the mains noise to the ground connection simply means that the ground connection is at the mains noise potential now. There always seemed to be significant noise currents flowing in the connections between different parts of the grounding system, begging the question which one really is ground? I think for this kind of filtering to work, a very good ground mat would be needed, as previously remarked. Most packaged mains filters are built with EMC regulations in mind, and since most of these only apply to frequencies above 150kHz, and the limits are more relaxed at the LF end of the range, the filters are not very effective in the LF range. I have had more luck with, firstly, eliminating what sources of noise I could (going around turning things on and off revealed a particularly noisy compact flourescent bulb), and secondly, experimenting with different receive antennas in different positions. The position of loop antennas can make a radical difference to the noise they pick up.

In fact, most mornings I see a quite abrupt drop in noise level a bit before 0700, well before streetlights go off. Haven't been able to identify the source of this noise change so far. Also short lived periods during the night. Both Dave and John are getting slightly better reception than I can achieve, particularly in the morning session - are you using the normal vertical antennas for reception ? Certainly haven't been able to make out as much of today's CW message as Dave's plot timed at 0800 today shows. I've been recording raw data, I/Q sampled at 3.9Hz and sending these to Bill VE3IQ for analysis. After filtering and smoothing the phase of the signal can be extracted, Hopefully, this will allow the propagation path to be characterised to levels greater than amplitude measurement alone will give. The on off keying does give a slight problem but after adequate filtering its effects can be removed leaving a plain carrier whose phase can be measured over the entire transmission period.

Not a "whole house" mains filter, but a radio room mains "filter". All main supply to my radio equipment is run via a single phase isolation transformer, having two shields. Thereby my radio equipment does not have any electrical continuity with the phase conductor, the return conductor and the protective conductor. In order to guarantee safety, I drove a separate grounding rod (9m deep) into garden ground close to the house and use this as my "private" safety conductor. The isolation transformer has its primary windings shielded and its secondary shielded individually. I do connect the primary shield with the "normal" house safety conductor, the secondary shield with my "private" safety conductor. As the secondary winding is split (to allow for 120/240 adaptation) I connect the center tap to the "private" safety conductor as well. Thereby my "private" mains becomes symmetrically in respect to my private ground. In your case, designing and constructing a whole house wiring, I would recommend to consider the following points: (1) you want to prevent conducted noise, coming along the house mains entrance, creep into your house mains distribution system (wiring) and distribute therein at will. (2) you operate several equipment being potential sources of mains noise (any equipment utilizing SMPS, uP control, SCR dimmers and the like). You maybe will be interested to prevent home made mains noise from distributing in your house mains distribution system (wiring). To prevent (1), you may use 3 single phase isolation transformers, or 1 triple-phase isolation transformer right after the electric meter. To prevent (2) you need to run your mains wiring in separated cables to the destinations. One cable for living room, one cable for kitchen, one cable for ... This is a minimum measure. Additionally you may put electical filters in each of those cables. Thereby you prevent distribution of mains noise from one room into the other. If you just want to have a clean mains supply for your radio room, you may perhaps adopt my solution described above. To speak about "mains noise" is somewhat unspecific, as there are several ways how noise may distribute and what frequency range is concerned. One way, how conducted noise can propagate in mains cables is, running in the phase conductor and returning in the neutral return conductor. Academically, the safety conductor is not involved. This is called differential mode of propagation. The other way of propagation is, conducted noise flows in both the phase conductor as well as the neutral return conductor in the same direction. Now the return path is the safety conductor. This is called the common mode of propagation. My a.m. isolation transformer is excelent in supressing the common mode propagation over a large range of frequencies. It is still effective for higher frequencies to suppress differential mode of propagation (approx. starting at 500 kHz). To increase suppression of differential mode noise, I intend to add differential mode chokes (inductors) plus capacitors from phase conductor to neutral return conductor at the primary side of my isolation transformer. Just some ideas which hopefuly are of some benefit. 73 de Gamal From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 11699 invoked from network); 23 Jan 2001 09:39:33 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by 10.226.25.101 with SMTP; 23 Jan 2001 09:39:33 -0000 Received: (qmail 6375 invoked from network); 23 Jan 2001 09:43:00 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 23 Jan 2001 09:43:00 -0000 Content-Transfer-Encoding: 8bit Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14KzrG-0007j6-00 for rsgb_lf_group-outgoing@blacksheep.org; Tue, 23 Jan 2001 09:35:22 +0000 Received: from bob.dera.gov.uk ([192.5.29.90]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14KzrE-0007j1-00 for rsgb_lf_group@blacksheep.org; Tue, 23 Jan 2001 09:35:20 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: by bob.dera.gov.uk; (8.8.8/1.3/10May95) id JAA31117; Tue, 23 Jan 2001 09:36:29 GMT Received: (qmail 32552 invoked from network); 23 Jan 2001 10:28:40 -0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from gauntlet.mail.dera.gov.uk (172.16.9.10) by baton.dera.gov.uk with SMTP; 23 Jan 2001 10:28:40 -0000 Received: by gauntlet.mail.dera.gov.uk; id KAA25014; Tue, 23 Jan 2001 10:20:04 GMT Received: from unknown(10.71.64.31) by gauntlet.mail.dera.gov.uk via smap (3.2) id xma024808; Tue, 23 Jan 01 10:18:56 GMT Received: from FRN-MAIL-3.dera.gov.uk (unverified) by mailguard.dera.gov.uk (Content Technologies SMTPRS 4.1.5) with ESMTP id for ; Tue, 23 Jan 2001 09:37:09 +0000 Received: by frn-mail-3.dera.gov.uk with Internet Mail Service (5.5.2650.21) id ; Tue, 23 Jan 2001 09:33:54 -0000 Message-ID: <65AECDF1F89AD411900400508BFC869F0D7549@pdw-mail-1.dera.gov.uk> From: "Talbot Andrew" To: rsgb_lf_group@blacksheep.org Subject: LF: RE: Accuracy of Soundcards, programs, and related stuff Date: Tue, 23 Jan 2001 09:33:52 -0000 MIME-Version: 1.0 X-Mailer: Internet Mail Service (5.5.2650.21) Content-Type: text/plain; charset=iso-8859-1; format=flowed Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Is it a coincidence I wonder, that the 'standard' Soundcard / CD sampling rate is a multiple of the squares of the small prime numbers. ie: 44100 = 2 * 2 * 3 * 3 * 5 * 5 * 7 * 7 Spooky !

I did measure the antenna current and the signal strength of DCF39, in both cases not the slightest difference. I did place the coil in back horizontal position after the test as it is not mechanical stable when vertical. If it is of any interest I could arrange a test with Dick (PA0SE) to measure the strength of my signal with the coil in both positions, but based on this first test I do not expect too much. Maybe some others can turn the loadingcoil and do this little test. 73, Rik ON7YD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 26433 invoked from network); 23 Jan 2001 09:00:30 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by extortion.plus.net with SMTP; 23 Jan 2001 09:00:30 -0000 Received: (qmail 7578 invoked from network); 23 Jan 2001 09:03:15 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 23 Jan 2001 09:03:15 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14KzA3-0007Rt-00 for rsgb_lf_group-outgoing@blacksheep.org; Tue, 23 Jan 2001 08:50:43 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from typhoon.mail.pipex.net ([158.43.128.27]) by post.thorcom.com with smtp (Exim 3.16 #1) id 14KzA3-0007Ro-00 for rsgb_lf_group@blacksheep.org; Tue, 23 Jan 2001 08:50:43 +0000 Received: (qmail 12553 invoked from network); 23 Jan 2001 08:50:30 -0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from useray39.uk.uudial.com (62.188.139.129) by smtp-2.dial.pipex.com with SMTP; 23 Jan 2001 08:50:30 -0000 From: "Nick" To: rsgb_lf_group@blacksheep.org Subject: Re: LF: Re: Mains Borne Noise Date: Tue, 23 Jan 2001 08:49:28 +0000 Message-ID: <97hq6tsnofej106nhgf0tj6ff1t6q1emo7@4ax.com> References: <015c01c0823d$a5506820$4959fd3e@compaq> <000401c084c9$19fa4960$ee34893e@robing> In-reply-to: <000401c084c9$19fa4960$ee34893e@robing> X-Mailer: Forte Agent 1.8/32.548 MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 8bit Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: On Mon, 22 Jan 2001 20:15:28 -0000, you wrote: >> Has anybody on the list got a "whole house" mains filter installed >> at their QTH? I work in EMC and this would be a very difficult concept to implement as most commercial filters are designed to filter against some reference plane (typically the metal cabinet of equipment). To successfully filter a domestic supply would either involve a filter that is designed not to need a significant earth impedance or a very large buried earth mat. I would not recommend any commercial filters without seeing the design.

For most broadcasters, the stereo pilot is one of those "out of sight, out of mind" things. 73, John KD4IDY From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 654 invoked from network); 23 Jan 2001 01:07:57 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by 10.226.25.101 with SMTP; 23 Jan 2001 01:07:57 -0000 Received: (qmail 29855 invoked from network); 23 Jan 2001 01:11:26 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 23 Jan 2001 01:11:26 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14Kru8-0005Ef-00 for rsgb_lf_group-outgoing@blacksheep.org; Tue, 23 Jan 2001 01:05:48 +0000 Received: from imo-r14.mx.aol.com ([152.163.225.68]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14Kru7-0005Ea-00 for rsgb_lf_group@blacksheep.org; Tue, 23 Jan 2001 01:05:47 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from WarmSpgs@aol.com by imo-r14.mx.aol.com (mail_out_v29.5.) id l.be.f011559 (16785) for ; Mon, 22 Jan 2001 20:04:46 -0500 (EST) From: WarmSpgs@aol.com Message-ID: Date: Mon, 22 Jan 2001 20:04:45 EST Subject: Re: LF: WWVB Doing testing in the field To: rsgb_lf_group@blacksheep.org MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII; format=flowed Content-Transfer-Encoding: 8bit X-Mailer: AOL 4.0 for Windows 95 sub 120 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: In a message dated 1/22/01 2:28:25 PM Eastern Standard Time, paulc@snet.net writes: << I asked if they were goingto put a schedule up on the outage page at there site, and they said there would be.

I am certain if used on 136KHz. this will assist in all cases of local QRN(M) but not certain whether it will help with distant QRM. The main problem for long distance QRM (Like Loran spurs) is adquate spacing for the two antenna for a satisfactory null. It would be possible to use a radio link for remote antennae. The other possibility is a big Adcock antenna and a goniometer system for anyone with the land?? Anyone have any thoughts??

To check the accuracy of the sound card clock, perhaps there is a simpler method, that doesn't require you to bring a TV near your computer. In my case this would be a bit difficult, as my shack is in the basement, and the TV is upstairs... If you tune an FM radio to a stereo station, there is a pilot signal at 19 kHz that is used to regenerate the carrier used for the left - right separation. At least this is true for Europe, don't know for the US. This reduced-amplitude pilot signal is clearly visible with any spectrogram-like program. I think its accuracy is comparable to that of the line synch of the TV signal, and needs only a lightweight portable FM radio. > to your the soundcard or -better- try to get one of those rare DSP boards. The DSP boards (I have three of them, the DSKC50, the DSKC30 and the EVM56002) use normal crystals, without oven, nor temperature compensated, so the only advantage is that they are not into the PC case, and the temperature excursion is lower. About the .INI vs. Registry issue, I think each method has its pros and cons. Personally, I prefer the Registry, but this is just a matter of personal preferences. Perhaps a right way could be to give the user the possibility to export (and import) the Registry settings to a text file, so that he can manually edit them, if need be. 73 Alberto I2PHD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 24614 invoked from network); 22 Jan 2001 22:32:55 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by excalibur.plus.net with SMTP; 22 Jan 2001 22:32:55 -0000 Received: (qmail 18407 invoked from network); 22 Jan 2001 22:27:13 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 22 Jan 2001 22:27:13 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14KpLc-0004GI-00 for rsgb_lf_group-outgoing@blacksheep.org; Mon, 22 Jan 2001 22:22:00 +0000 Received: from [212.159.14.225] (helo=murphys-outbound.servers.plus.net) by post.thorcom.com with smtp (Exim 3.16 #1) id 14KpLb-0004GA-00 for rsgb_lf_group@blacksheep.org; Mon, 22 Jan 2001 22:21:59 +0000 Received: (qmail 7701 invoked from network); 22 Jan 2001 22:21:12 -0000 Received: from unknown (HELO picks) (212.159.56.130) by murphys with SMTP; 22 Jan 2001 22:21:12 -0000 Message-ID: <007801c084c2$d2d57420$82389fd4@f9.net.uk> From: "Dave" To: rsgb_lf_group@blacksheep.org References: <005301c084b1$4bb4ecc0$82389fd4@f9.net.uk> <3A6CAD44.D94BE899@usa.net> Subject: Re: LF: Copy of VA3LK Date: Mon, 22 Jan 2001 22:29:44 -0000 MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.00.2615.200 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Alberto > thanks.

I do have a little trouble with Spectran but it runs OK It always gives the error message that the soundcard is in use by another application but, if you ignore that, it works until you want to change something. That is on the shack PC with a Creative Labs card. I have a lot of trouble with my laptop (P100 and ESS sound chip) which only seems to like Spectrogram and Argo, Argo runs fast enough to give good resolution, whereas Spectrogram goes too slowly.

If the other program you are referring to is Spectran, well, Spectran has a much thougher job to do, as it pretends to output the filtered audio signal in full duplex, and to bypass the entire process of digitization when you press the PassThrough button. In addition, measures have to be taken to insure that what you hear is only the processed signal, and not a mixture with the input signal. This implies a complete control of the soundcard mixer. Unfortunately not all the mixer implementations are created equal, some have the selectors, others the switches, some have 'Select' controls, others have the opposite, the 'Mute' controls.... etc. etc. All this has the consequence that, at least in its present stage, Spectran works on many sound cards, but not on some models, notably the SB PCI128 family. But, albeit very slowly, we are trying to sort out all of this mess.... In Argo, things are much simpler. When you press the 'Select Input' choice, all what Argo does is to present you the Windows mixer panel, and then it's up to you to do the correct choice... unfortunately this cannot be done in Spectran... 73 Alberto I2PHD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 20020 invoked from network); 22 Jan 2001 20:31:28 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by excalibur.plus.net with SMTP; 22 Jan 2001 20:31:28 -0000 Received: (qmail 19411 invoked from network); 22 Jan 2001 20:25:46 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 22 Jan 2001 20:25:46 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14KnOC-0003eZ-00 for rsgb_lf_group-outgoing@blacksheep.org; Mon, 22 Jan 2001 20:16:32 +0000 Received: from [212.159.14.227] (helo=warrior-outbound.servers.plus.net) by post.thorcom.com with smtp (Exim 3.16 #1) id 14KnOA-0003eT-00 for rsgb_lf_group@blacksheep.org; Mon, 22 Jan 2001 20:16:30 +0000 Received: (qmail 8361 invoked from network); 22 Jan 2001 20:15:46 -0000 Received: from unknown (HELO picks) (212.159.56.130) by warrior with SMTP; 22 Jan 2001 20:15:46 -0000 Message-ID: <005301c084b1$4bb4ecc0$82389fd4@f9.net.uk> From: "Dave" To: "LF Group" Subject: LF: Copy of VA3LK Date: Mon, 22 Jan 2001 20:24:17 -0000 MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.00.2615.200 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Dear all.

Here are the results from a few tests I did on that. They do not have to be 100% true for "your" PC, but I hope they are worth thinking about: 1.) The soundcard's 8000 Hz sample rate is not good on both PCs I tested. They were off the actual sample rate by some Hertz(!!) on my old notebook. 2.) Also stay away from all sample rates except 11025, 22050 or 44100 samples per second. If you need lower sample rates, decimate the input signal by two or three. If the input spectrum does not contain frequencies above half of the *decimated* sample rate, you don't even need a proper software-based anti-alias filter (a quick and easy integrate-and-dump filter as used in SpecLab will do, it just takes a few additional nanoseconds(!) per sample. You only have to process every second or third sample in the FFT. The IF filter in your receiver will reduce the 'aliasing' frequencies above 2 kHz anyway). 3.) A possibility to check the accuracy of the sample rate is this (with some limitations): Let the soundcard run at 44100 samples/second, put a pice of wire into the mic input (or even the line input) and turn on the TV. Use the largest FFT size your program supports, use the highest level of "integration". You should see a clear spectrum line at exactly 1/64us = 15625.0 Hz. This allows you to calculate a quite "exact" sample rate (for example, 44100.05 samples/second). Chances are good, that the lower sample rates are fractions of this "corrected" sample rate (in this example, 22050.025 Hz and 11025.0125 Hz ). In programs using the soundcard like ARGO, Spectran, and all the others, a small table can be included in a "configuration dialog" where the user can enter the corrected sampling frequency (or a correction factor for every supported sample rate). To say it again, most soundcards are not that bad if the "standard" sample rates are used. And - I guess - though they use cheap computer crystals, they do not drift too fast (but I must admit, I did not open my windows to check the soundcard's stability if the room temperature drops from +19°C to -5°C). If you really need an absolute milli-Hertz ACCURACY (and not just a mHz RESOLUTION, because you cannot find a commercial station with a steady carrier), you may have to attach a small crystal oven to your the soundcard or -better- try to get one of those rare DSP boards. A (possible?) ''software solution' to improve frequency accuracy (warning, may contain sarcasm, but about 0.5ppm of a good idea): Let the card run on 44100 samp/sec in "16 bit stereo". Connect the TV-line-sync-signal to the soundcard's left channel. Connect the audio from the longwave RX (or whatever you want to analyze) to the right channel. Develop a sophisticated software which removes the phase jumps from the interlaced TV signal and/or drives an accurate software PLL . Use the (PLL'ed) reference signal to continously monitor the soundcard's clock deviation. If you don't have your own Caesium standard for the RX, you may even lock your receiver's main oscillator to the software-based reference. Make shure that you are close enough to the TV transmitter so no phase jitter from a varying propagation path can affect the reference. Make sure that the program does not miss a single sample in a couple of days (a tough job under Windoze, believe me...). Etc, etc, etc. A personal opinion about "INI files" versus "Windoze Registry" (non-programmers please stop reading here, it gets boring): I am still using the old-style INI files in my programs, because they can easily be copied to others PCs to transfer all the settings (remeber, they are plain text files which you can even modify with a simple text editor). You can locate the INI files in the directory where the executable program is located (yes, it can be done, though almost no-one else seems to do it). There is no need to put all INI files into the Windoze directory ! In my humble opinion, doing so will turn the Windows diretory into a complete mess, and, as Alberto wrote, you always have trouble trying to find them later. Saving the INI file in the directory of the executable has some advantages (If you like to know how, drop me a line). The user can get back to the "very default settings" of the program by deleting the configuration file. The program will automatically create a new one with the 'built-in' default settings.

It does not really matter if the dots merge together if the purpose is only to identify a signal is present.To facilitate this, the signal I intend to use will have about 5 90s dashes and spaces, followed by a "missing" dash. Hopefully, this will make it a bit more distinctive, and if viewed at higher resolution, the dashes will merge to produce one long dash and a shorter space. I think this should be easy to set up using ON7YD's QRS keyer software in beacon mode, which will also do normal CW ID's How narrow a frequency range we can use depends on how accurately the TX frequency can be set - my synthesiser does 0.1Hz steps, and if everybody had the same, quite a few people could fit into 2Hz bandwidth. But whether this can be done depends on the equipment at the individual stations involved. Since Larry's signal is visible with quite good SNR at times in 42mHz resolution, and VE1ZJ has seen several signals with 0.3Hz resolution, I think 42mHz resolution might do the job. If it does not, it will certainly take a major re-think to achieve a QSO!

Marco IK1ODO has asked a similar thing, i.e. the storing of a correction factor. Perhaps I could store two values, a multiplicative corrective factor to cope with the sampling rate error, and an additive one, for the RX error. Let's see. Probably I will implement it for the next version, though not using a .INI file, but rather the registry, so you don't have to worry about which directory you used to store that .INI 73 Alberto I2PHD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 7717 invoked from network); 22 Jan 2001 15:57:52 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by 10.226.25.101 with SMTP; 22 Jan 2001 15:57:52 -0000 Received: (qmail 620 invoked from network); 22 Jan 2001 16:01:21 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 22 Jan 2001 16:01:21 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14KjIc-0002HN-00 for rsgb_lf_group-outgoing@blacksheep.org; Mon, 22 Jan 2001 15:54:30 +0000 Received: from [200.231.181.97] (helo=ntweb.globocabo.com.br) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14KjIb-0002HF-00 for rsgb_lf_group@blacksheep.org; Mon, 22 Jan 2001 15:54:29 +0000 Received: from spovdesi1625 (SPOVD-ESI-1625 [5.8.10.82]) by ntweb.globocabo.com.br with SMTP (Microsoft Exchange Internet Mail Service Version 5.5.2653.13) id D3JJ1DLP; Mon, 22 Jan 2001 13:50:03 -0300 Message-ID: <014901c08493$63544560$520a0805@globocabo.com.br> From: "PY3CRX PY2PLL" To: rsgb_lf_group@blacksheep.org References: <65AECDF1F89AD411900400508BFC869F0D7544@pdw-mail-1.dera.gov.uk> Subject: LF: Re: RE: More Tests Date: Mon, 22 Jan 2001 14:49:53 -0200 MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.50.4133.2400 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Hi ... > How easy would it be to include a facility for storing the exact > measured sampling rate in a .INI file that can be called up when the > software is run.

If you specify the filename radix, complete with the path, and the interval in seconds (by choosing Capture, then Setup), Argo duly respects what you specified. I have done many screen captures and I have never observed the behaviour you mention. The only caveat is that you must not cover the Argo window with another, otherwise this foreground window will be captured instead. This seems to be unavoidable.

G3PLX included such a facility in PSK31 to allow for the gross errors seen on some machines - several Hz on a 1kHz tone in a few cases. There are enough highly accurate transmissions around for calibration, so if the cal factor can be saved (and doesn't drift too much !) one area of uncertainty is removed.

This is the period during which I operate in the FOC Marathon CW activity which is now the only organized on air social activity I participate in. I could however let run the LF receiving system during that period on a single frequency with about 2 Hz of bandwidth maximum. Once I have had my annual dose of operating activity I will get back to the LF program. For those of you who may not be aware, my remote HF station is co-located with the LF transmitter in the same building and the LF transmitter does a serious hammer job on the HF station receiver. The TS-570 is a great little radio, but the RF noise from the LF transmitter, some 10 feet away in the same room, prevents simultaneous HF operation below 20 meters most of the time.

Carron's patent 0043591 for his toroid antenna runs to 67 pages! and has been in the public domain for some time.(date of filing 13/7/1981) It quotes the relationship of vector and scalar potential to electric and magnetic fields and the permeability of free space but does not use these units in describing the action of his toroid antennas. > All of this may seem to be a bit too theoretical because one cannot >actually see the vector potential, one only observes the effects of its >presence, but, after all, the same applies to magnetism.

See PA0SE's instrument in the LF Handbook, page 83, for measuring electromagnetic field strength. Now, has anyone come up with an instrument for measuring Vector Potential? A passage from Basic Electrotechnics, by B. L. Goodlet states: "If the vector potential at a point due to current or flux is known, it is possible to calculate the induced electric field at that point if the current or flux changes". This implies that if Vector Potential cannot be measured then it must be a mathematical go-between to simplify calculations. While in the rarefied atmosphere of Electromagnetic Theory it appears that we have Electric Vector Potential, Magnetic Vector Potential, and Electric Scalar potential. There may be a Magnetic Scalar Potential but I haven't seen one yet. Until someone can convince me otherwise I feel that these are just mathematical entities. Whether they will provide the key to a better LF antenna than the one devised by Marconi remains to be seen..

Tuning error and soundcard accuracy do not have exactly the same effect on the apparent observed frequency line in Argo or any DSP system where the sampling rate is not locked to the same frequency as used for tuning. Tuning error is reflected as a frequency shift which applies equally to all tones within an audio bandwidth. Sampling rate error appears to change the tones by an amount proportional to frequency. eg at 8000 Hz sampling rate + 10ppm = 8000.08 Hz a 1kHz tone will appear at to be 999.99Hz (0.01 Hz low), 1500Hz will appear to be 1499.985Hz (0.015Hz low) etc If the receiver tuning is 0.1 Hz in error these would be 999.9 ands 1499.9 respectively. So to calibrate out both uncertainties a minimum of two measurements are needed. Here is a procedure to do this : Tune into a transmission whose frequency is known EXACTLY - such as MSF at 60kHz or the centre of Loran at 100kHz - using your favourite piece of narrow band software and receiver as used normally. Adjust tuning for an audio tone of 500Hz and measure the exact tone frequency resulting. Then alter the receiver tuning to get a tone of 2500Hz and measure this figure exactly. The difference between the two measured frequencies expressed as a fraction of the wanted separation (here 2kHz) is the soundcard sampling error rate. Any error that applies equally to both tones is due to receiver tuning alone. Obviously the widest tone separation as possible is desired to minimise measurement error. This test does pre-suppose that the error in the receiver is determined only by its internal oscillators and not by errors in transferring the desired frequency to the display. Most modern PLL and DDS controlled receivers do in fact generate exactly what the dial says, subject only to their oscillator calibration. In most cases the receiver frequency setting error should swamp that of the soundcard but this may always not necessarily be the case. For example an IC746 with TCXO option and trimmed to 0.2ppm accuracy (it can be done) used to receive directly on 137kHz will exhibit an error of 0.027 Hz as all frequencies within the reciver are locked to the master source. A laptop integral soundcard could easily be 30ppm out even if the oscillator is 'meant' to be exact ie. not allowing for poor implementation which can give errors up to 0.2 percent !!! 30ppm would give 0.03Hz at 1kHz tone and 0.06Hz at 2kHz tone frequency, error exceeding that from the receiver.

Could have been longer but Argo crashed soon after, probably because of the way it fills up the hard disk with photos taken every 1 minute, despite the fact that at the dot width of 30sec, it takes 15 minutes to complete a window width. It also seems to ignore the folder that you supply and puts them whereever it pleases. Unfortunately I didn't actually see his call sign, because the message faded out at just that point, but it was exactly on the frequency that Larry stated and was clearly QRSS. The 30sec maximum is a real problem when assembling the jig-saw like puzzle the following morning. After a frustrating week using Easygram to try to see Larry's signal, I finally understand why I could not see his signal with any certainty and why my observations did not match those of Andy and Jim. The best resolution that Easygram can achieve is about the same as Spectrogram 0.3 Hz and this is simply not enough. It is enough for VE1ZZ's signals, but I now realise that these are much stronger. Larry is considerably further to the West, perhaps 500 km or so. The problem that I have found with Spectran in the past is that it can be difficult to see the start and end of QRSS dots and dashes, whereas Spectrogram manages to do this quite well. I mistakenly thought that this would be good for Larry's signals too. For really weak signals one needs Spectran or Argo (both from the same stable and with the same 0.03 Hz resolution) at highest resolution. To avoid the blurring, 3 sec dots will not do. 30 seconds might be good enough but 90 seconds as at present may be necessary. Longer will probably not help, because of the QSB on the signal. Now that Larry is transmitting QRSS(SSSS.....) it is possible to identify the signal from its content, whereas just sending dashes as he was at the beginning of the week, makes identification in the presence of QSB only possible by knowing the exact frequency of the received signal and matching it to the transmitted frequency, a non-trivial matter. I have found that there are three main sources of error in determining the exact frequency of a line on the screen: Rx accuracy Sound card/ Software accuracy Measuring the position of the line In my case, the Rx accuracy is limited by the 2.655 Hz tuning steps, which means that one can be out by up to half this amount approx. 1.35 Hz, but it is possible to calculate this error. The Sound card/ Software accuracy I have found to add up to a further 0.5 Hz to this (others have reported 2Hz). Interestingly I found Argo different from Spectran by 0.4 Hz approx. None of the packages allow measuring the position of the line to an accuracy much better than 0.1Hz, although with a accurate scale one can improve this to about 0.05Hz. Much better isn't really possible because of the thickness of the lines and the non-linearity of screen images. My method of calibrating combined Rx/Soundcard/Software package was to match 30 or so Loran lines, using a table of differences. I make Jim's "two carriers on almost exactly 137.790" to be at: 137789.85 and 137790.05 Hz to an accuracy of 0.05Hz. I found them to be fading and blurring but present most of the night of 21/22 January. Jim reported a signal on 137787.5. I saw this too but it is not Loran. The Loran line is at 137787.8473. I can see the Loran line as well when the loop is orientated N/S. After careful checking of frequenciesI am now sure that I am not seeing Loran lines other than from the Lessay/Sylt chains. Some of the lines reported by Andy appear to be offset in frequency by a small amount, when compared with the Loran lines. I plan to use the new version of Argo, when it settles down and hopefully the problems with capturing images have been sorted. At the moment this is the only tool which can do the job. The map of this part of our band, that I have created will be posted on my web site. 73, John, G4CNN e-mail: computernetworks@excite.com url: www.g4cnn.f2s.com _______________________________________________________ Send a cool gift with your E-Card http://www.bluemountain.com/giftcenter/ From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 2354 invoked from network); 22 Jan 2001 14:48:43 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by extortion.plus.net with SMTP; 22 Jan 2001 14:48:43 -0000 Received: (qmail 3477 invoked from network); 22 Jan 2001 14:51:28 -0000 Content-Transfer-Encoding: 8bit Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 22 Jan 2001 14:51:28 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14KiA2-0001p5-00 for rsgb_lf_group-outgoing@blacksheep.org; Mon, 22 Jan 2001 14:41:34 +0000 Received: from ns1.swh.sk ([192.108.125.33]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14KiA0-0001p0-00 for rsgb_lf_group@blacksheep.org; Mon, 22 Jan 2001 14:41:32 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from hermes.swh.sk (hermes [139.24.136.129]) by ns1.swh.sk (8.9.1/8.9.1) with ESMTP id PAA22567 for ; Mon, 22 Jan 2001 15:41:15 +0100 Received: from btss101a.swh.sk (btss.swh.sk [139.24.136.15]) by hermes.swh.sk (8.9.3/8.9.2) with ESMTP id PAA11433 for ; Mon, 22 Jan 2001 15:41:11 +0100 (MET) Received: by btss.swh.sk with Internet Mail Service (5.5.2653.19) id ; Mon, 22 Jan 2001 15:41:09 +0100 Message-ID: <29BDD4F529FCD311B631009027357C4E01F69F36@btss103a.swh.sk> From: "Gasparik Richard" To: "Rsgb_Lf_Group \(E-mail\)" Subject: LF: Some grams and sounds...

Geri's note on birch leaves leads me to relay my experience with my aerial. I have been waiting all Summer for the tree surgeon to lop my Liquidambars, which were up to 20m. After the gales damaged one of my homemade masts and brought down all my aerials the tree surgeon turned up and the trees were duly topped. I have rebuilt both mast and 136 aerial as before. The feedpoint resistance has reduced from 144ohm to around 50ohm. With a transmitter output of 250v peak to peak or about 156W, which ignoring loss in the 50m of coax, implies a feedpoint resistance of about 40ohm with the 2A aerial current I was measuring. Over three times improvement. The before photograph is on my web site. I hope to post an "after" picture. With regard to the kind invitations for qsos I simply have to tidy up the system where my Rx is upstairs and the Tx is in the cellar two floors down and two flights of stairs in between. The "over" delay is only suitable for QRS. 73, Brian 73 Brian CT1DRP IN51QD 41 09 58N 08 39 11W http://homepage.esoterica.pt/~brian From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 3056 invoked from network); 22 Jan 2001 14:28:00 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by extortion.plus.net with SMTP; 22 Jan 2001 14:28:00 -0000 Received: (qmail 28748 invoked from network); 22 Jan 2001 14:30:46 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 22 Jan 2001 14:30:46 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14KhsP-0001jM-00 for rsgb_lf_group-outgoing@blacksheep.org; Mon, 22 Jan 2001 14:23:21 +0000 Received: from mail6.svr.pol.co.uk ([195.92.193.212]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14KhsN-0001jH-00 for rsgb_lf_group@blacksheep.org; Mon, 22 Jan 2001 14:23:19 +0000 Received: from modem-165.edoras.dialup.pol.co.uk ([62.136.171.165] helo=lvm) by mail6.svr.pol.co.uk with smtp (Exim 3.13 #0) id 14Khs9-00009k-00 for rsgb_lf_group@blacksheep.org; Mon, 22 Jan 2001 14:23:06 +0000 Message-ID: <000101c0847f$59993620$a5ab883e@lvm> From: "LAWRENCE MAYHEAD" To: "rsgb lf group" Subject: LF: Re.

So there really is no reason why a two way cannot soon be effected. I will be very happy to transmit a beacon signal if this will help to get some stations listening on the other side.

If you want to dig deep into the noise, you must use resolutions of 5 or 10 milli Hertz. At these resolutions the span covered by a spectrogram is at maximum a couple of Hertz, so the 10 or 20 Hz spread would mean that the biggest part of the stations will be outside the screen. 73 Alberto I2PHD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 3153 invoked from network); 22 Jan 2001 13:59:28 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by excalibur.plus.net with SMTP; 22 Jan 2001 13:59:28 -0000 Received: (qmail 20993 invoked from network); 22 Jan 2001 13:53:46 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 22 Jan 2001 13:53:46 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14KhIQ-0001Vc-00 for rsgb_lf_group-outgoing@blacksheep.org; Mon, 22 Jan 2001 13:46:10 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from d12lmsgate-3.de.ibm.com ([195.212.91.201]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14KhIN-0001VV-00 for rsgb_lf_group@blacksheep.org; Mon, 22 Jan 2001 13:46:08 +0000 Received: from d12relay02.de.ibm.com (d12relay02.de.ibm.com [9.165.215.23]) by d12lmsgate-3.de.ibm.com (1.0.0) with ESMTP id OAA51502 for ; Mon, 22 Jan 2001 14:45:17 +0100 Received: from usa.net (ss4.bld.socks.ibm.com [9.14.4.69]) by d12relay02.de.ibm.com (8.8.8m3/NCO v4.95) with ESMTP id OAA203142 for ; Mon, 22 Jan 2001 14:44:59 +0100 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Message-ID: <3A6C390C.FA0B5286@usa.net> Date: Mon, 22 Jan 2001 14:43:40 +0100 From: "Alberto di Bene" Organization: Undisclosed X-Mailer: Mozilla 4.76 [en] (Win95; U) X-Accept-Language: en MIME-Version: 1.0 To: rsgb_lf_group@blacksheep.org Subject: LF: Argo, capture timing References: <000401c08406$1bbcc480$056401d5@Alan.Meliabtinternet.com> Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 8bit Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Alan Melia wrote: > [snip] > But that is maybe a useful thought , you could set the default dependent > upon the mode setting, as that defines the screen width.

I use an old ISA AWE32 SB card, and, as far as I can tell, this error is not present. I haven't checked on my laptop, a Thinkpad with a Crystal Sound chip, yet. While we are at this, I take this opportunity to answer to a private message of David, G0MRF, who signalled me a frequency error on the 3 and 10 sec/dot modes, but not on the full band view mode. I think that the problem is that the 5512 S/s sampling rate is not a standard one, and is implemented differently by the various manufacturers. In Argo all modes, except the full band view, use this sampling rate. On my sound card, I see no frequency errors when using this sampling rate, but maybe this is not true for every card model. It would be useful to have reports on tests done on many sound cards. > > I used the Magnitude Squared estimator and left the AGC on.

By dawn, things were back to normal, and the best reception occured around 0700. Periods of good reception were 0140-0210, 0250-0340, 0430-0515, 0550-0610, 0650-0805. QRN seemed lower than normal. I wonder if the altered propagation was connected with the solar flare reported earlier? In correspondence with Larry on the subject of a possible 2 way QSO, the need for some receiving tests in the Europe -> North America direction has become obvious. Both VA3LK and VE1ZZ can be received fairly routinely here by several stations, however so far only VE1ZJ has definitely seen any Eu signals (most recently in cooperation with VE1ZZ of course). Since John is probably stuck with 60Hz noise problems at his QTH until the weather warms up, now is a good time to make a concerted effort to see what signals can be received by other NA stations. Since 3s/dot slow CW has not been good enough for this so far, I suggest we do something like this: As many European stations as possible transmit very long dashes (90seconds for example), within a very narrow frequency range (perhaps 20Hz maximum - 10Hz would be better), which has been selected by the interested parties on the North American side as most suitable for reception. This way, high resolution spectrograms can be obtained by the receiving stations of a frequency range containing all the strongest available signals. At the moment this seems to be the most sensitive weak-signal detection method available. Once a positive result has been obtained, we will have a handle on the signal levels that can be expected, and will be able to make an intelligent guess at the appropriate modulation techniques, QSO formats, etc. that will work for a 2 way QSO. I guess there are several stations on both sides of the pond who already have the equipment needed to take part, so how about doing something in the next week or so?

To All from PA0SE
 
Sometimes a fellow amateur tells me he would like to become active on LF and asks my advice. I tell him/her to buy The low frequency experimenters handbook and/or the older Source book and to read what has been published on LF in our magazine Electron. After handing out some tips on receiving invariably the question comes what the best times are to listen for a signal. My answer has always been "Saturday and Sunday morning".  But I'm afraid that won't help the newcomer much anymore because there are hardly any signals to be heard nowadays. Perhaps from time to time a CQ, most of the time not being answered and some QRSS, which is unlikely to be recognised by a newcomer as an amateur signal.
I accept that to bridge the Atlantic Ocean is much more challenging than a normal CW QSO within Europe but nevertheless I would like to hear some more traditional activity on Saturday and Sunday morning, as it was a year or more ago.

Yes, I wondered if a coating of salt from tthe sea some 400m away had precipitated the event. As regards plastic as an insulator - when I first located coils outside they got wet but this did not initally seem to cause any losses. If you tried to dry them it the losses got a lot worse befor they got better. I then put a plastic bag over the coil, see page 13 of LF book, and this proved so successful I have stayed with it. The plastic does not get warm (to the touch with the transmitter off!) although frost on the plastic next to the coil windings gradually disappears during long QRSS sessions. I test the antenna by inspecting it in the dark with the transmitter on. With high power you can just see corona on imperfectly made joints or on dirty insulators. Last night had a pleasant supprise. I heard Finbar, EI0CF, calling CQ. We had a QSO; it was, apparently, his first LF QSO this year. Regards, Peter, G3LDO .

As I did not see it in the menu, I must have thought it was automatic. Oh dear what a stupid boy.....I reckon my brain has got frazzled with over exposure to Win95!! It was a bit fraught. But that is maybe a useful thought , you could set the default dependent upon the mode setting, as that defines the screen width. A value slightly less than a screen width would allow accurate 'pasting' of successive windows. This would be useful as it is not all that obvious, when you begin a slow scan, how much time it will take to fill a screen width. Anyone wanting odd periods between saves to align with transmissions like Jacks could over type it. Long dot modes would be very interesting, even though it looks as though Larry may be able to reduce the dot length a bit. I guess the problem is going to be going the other way, as Larry is generating a respectable field strength now. But this could be a easy way to get to grips with the S/N on 9kHz as well. I am interested to see it suggested that the '2 Hz LF' is a common error on all the cards. Maybe this is a divide error like Bill had to deal with on Africa. I used the Magnitude Squared estimator and left the AGC on. Calibration by a sig-gen coupling into the aerial and being measured to 0.1Hz resolution on a counter referenced to Droitwich. The interesting thing is that there is little sign of drift over two nights. The RX has a TCXO and has been ON continuously for four months, but the soundcard seems to perform adequately considering that the usual 'computer grade' crystals are not usually very good quality..... and the computer does get switched on an off.

It contains a couple of errors : the first shows when you set the 30s dots mode, and the 120s dots mode scale is displayed instead. The second error causes the 90s dots mode display to be shifted and scaled wrongly. I have upoaded an amended package with the first error corrected, and the 90s dots choice disabled, pending a solution. I found the cause of the error, but need a bit more time to choose the right solution. Thanks to Marco IK1ODO who quickly tested the pgm and pointed me to the errors.

The top spacer was insulated from the mast by a couple of ceramic insulators shown in Fig 4.10. While testing this antenna prior to the VE1ZZ tests a dramatic and noisy pyrotechnic display occurred across one of these insulators . I lowered the antenna and cleaned the insulators and the problem seemed to go away. But it occurred again. I inspected the insulator and found it was cracked all round and that the top spacer was only held by the other insulator. I modified the antenna so that the spacer was fixed directly to the mast and the wires supported by a couple of PA0SE brown ceramic insulators. The antenna was tried several times and, apart from a reduction in antenna capacitance, it worked fine. Today I had a phone call from Brian, CT1DRP. We have conducted several tests in the past - he has received my 136kHz and 73kHz signals and I have received his 136kHz signals but we never have had a QSO. Brian had renewed his mast (damaged in gales) and cut lopped some trees and could now get 2amps into his antenna with 200watts. We decided on a QRSS QSO. I checked the band at 1630 and it was clear of signals. Due to some restrictions we decided on 136.4kHz (at the risk of being 'flamed' again on e-mail by a couple of CW only operators). I transmitted to Brian and he transmitted to me - we were both receiving each other very well. When I put it over for an acknowledgement of my report -nothing! The receiver was dead. The problem turned out to be the antenna. The nylon cord fixing the insulator to the spacer had broken - no sign of any burning. It had been raining heavily all day today. I replaced the nylon cord with copper wire and tried again later. This time (1820) we made it, conditions not so good with the signal down and QRN up. Brian is going to improve the operating set-up. He also has a Decca transmitter so look out for a good signal from CT1 in the future.

Then I decided to implement a suggestion by Larry, VA3LK, who had asked for a slowed down version of Argo, more compatible with the long dashes he is sending out in these days. So I modified the program, adding three new modes, 60, 90 and 120 sec/dot, and the choice of three refresh speeds for each mode. The highest resolution is now 5 milli Hertz, which probably is already beyond the stability of the quartz on the sound card that determines the sampling rate... I chose the refresh speed and the tick intervals somewhat arbitrarily, and am open to suggestions.

I spent many years asking the same question and the usual answer that I got was that it was something to do with fluid mechanics or Maxwell's equations (which were based on fluid mechanics). As you correctly state there is something which is denoted by the vector A which, when it curls, produces the magnetic field, H. Hence, mathematically it is just a mysterious function, first recognised circa 1850, which, when it curls, produces the magnetic field. Hence the later association of it with the term Magnetic vector potential. It was later found that one could derive all of Maxwel',s equations from this single equation, so it began to seem that there was something more to it than just a pretty name. It was later discovered (circa 1930) that the RETARDED potential emitted from an oscillator, accelerated electron, or what you will ( i.e.the signal emitted from a distant transmitter at any wavelength) corresponded to this same vector potential and its polarisation in free space always remained parallel to the distant source. The next breakthrough came circa 1960 when Abranov and Bohm wrote a letter to Nature prophesising, on very good grounds, that in electron interference experiments, where a beam of electrons is fired at a double slit, it should be possible to change the phase of the interference pattern on the screen behind the slits by introducing a small source of vector potential, derived of its magnetic field component, eg by using a very long thin solenoid or, in later work a tiny toroidal coil, half way between the slits. This was later demonstrated many times experimentally and it was clearly shown that only the vector potential was responsible for the phenomenon, so some people, mainly physicists at that time, began to have a real respect for it. The engineers were much slower at recognising its importance in radio signal emission and radiation but in the last decade it has recieved considerable attention in the radio research laboratories in the USA, especially those concerned with the defence industry. As an example of the fundamental nature of the vector potential, in the last few years there have been a number of papers in the American journals from research labs and defence consultants concerning contra-wound toroidal antennas. By superimposing a toroidal coil with a left hand thread upon a toroidal coil with a right hand thread one can cancel out the magnetic field but the torus still radiates with no magnetic field within it or escaping directly from it. This trick, which I originally demonstrated with a reflecting plate superimpopsing an inverted image on the torus, but can be done directly at very low power level by winding a left handed toroid on top of one with a right hand thread, clearly demonstrates that only the vector potential is required for radiation, vide the current American litterature in particular an early paper by Carron, N.J: American Journal of Physics,1995, 63, pp 99-103, Carron was unaware of my experimental work at the time. Mathematically it all makes simple sense because one can derive all of Maxwell's equations from the curl and the divergence of a single property, the vector potential. Incidentally this immediately shows that, even the lowest frequencies, radio radiation is quantised, ie in separate photons a few miles long, but that is another story which I am hoping to publish elsewhere, but see an introduction in Jennison, R.C: I.E,E proceedings - Microwaves, Antennas and Propagation, Vol 146,Feb 1999 pp 91-93 (but note an error in draughtmanship in Fig 1 where the plus and minus signs on the right side of the diagram appear in the wrong order, they should coincide with those on the left)! All of this may seem to be a bit too theoretical because one cannot actually see the vector potential, one only observes the effects of its presence, but, after all, the same applies to magnetism. One never observes a magnetic field, - only the effects that it produces. However, radio hams tend to be very practical people so how does this vector potential behave in practical circumstances? A few weeks ago I constructed a device to put it to the test. The effect of the earth swallowing up an observeable proportion of the transmitted power tends to appear below about two megaHertz, so I tried an experiment on 'top band'. I designed an antenna only 40 cms in diameter which relied almost entirely upon the emmision of vector potential and was only 2 feet above the ground with a series of small metal plates (tobacco tin lids) and eight tiny coils all confined within the same diameter of 40 cms. A two metre co-axial cable connected this curious antenna to the TX. When I tried it out I received reports on my ssb transmission in excess of S5 from all parts of the UK (i.e. over 500 kMs from my QTH in Canterbury.). I am now in the process of constructing a somewhat similar (and more expensive!) version to try on the LF bands - just to prove the point. For the benefit of any other readers the term CURL just means that the entity travels in a curved track and the DIVERGENCE means that it sprays out in the manner of the spreading fine streams of water from a rose on a watering can or garden hosepipe. It may be of interest to note that a curling vector cannot diverge at the same time so that in any circumstances where they appear to do so one is actualy dealing with a cluster of independent vectors - e.g. photons, but more of that later! 73, Roger, G2AJV.

The QRN level seemed rather high, adding about 5-10dB to the noise floor, however, Larry's signal also seemed to be a few dB stronger, so copy was still fairly good. As before, there were several periods of good copy, interspersed with fades where only odd dots or weak traces of signal were visible. The periods of good copy were 2220-2240, 0040-0150, 0225-0320, 0345-0400, 0715- 0745, 0825-0840. The signals seen around dawn are getting quite weak, but the noise level also drops off at this time. I have yet to see anything before about 2200 in the evening. >From the other reports that are coming in, it would seem that most people equipped for QRSS operation should be able to detect Larry's signals; the important thing compared to the "faster" QRSS is to obtain high resolution and accurate frequency calibration of the receiver, so you know where to look for the signal. Here are some details of the methods I am using: I am currently using a W&G SPM19 level meter with external homebrew preselector and demodulator, and DL4YHF's "Spectrum Lab" spectrogram software. This setup has the advantage of very good frequency stability, but I think most synthesised receivers would be able to maintain the +/- a couple of Hz per night which is probably required. The frequency error of 2Hz on the soundcard seems to be something of a standard.... the easiest way to calibrate the frequency within a fraction of a Hz is to look at the Loran lines; in my QTH, (SE England), there are lines at 137.78785, 137.79171, 137.79528 kHz. G4CNN has produced lists of frequencies from other Loran chains. I believe Loran uses a caesium clock for a reference, so they should be pretty accurate. They had to come in handy for something! The transmit frequency does not seem to have drifted measurably. The spectrogram software needs to have higher resolution than the 0.3Hz that seems to be optimum for 3s/dot QRSS. Spectrum lab goes down to 0.042Hz (11k sample rate, divided by 4, 65k point FFT, average of 2 FFTs selected in the "spectrum" menu). It also has an input monitor 'scope display, so you can check the A/D converter is not being overloaded by the QRN. The brightness and contrast controls can be set for high contrast (about 20dB for the full colour spectrum), which is good for readability, but less contrast is better for monitoring the general signal level. The spectrum width is set to 5Hz or 10Hz - another reason to calibrate the frequency carefully. I find that the receiver generates a weak spurious signal at it's center frequency; it is worth checking for this kind of thing during the day. I set the timebase for about 35 mins per screen (can't remember actual figure), and setting the image capture to once every 30 minutes means I can go and get some sleep sometimes! I have been using a large single turn loop antenna, which I mentioned before on the reflector, which seems to work quite well and gets rid of most of the Loran lines. But I think the TX inverted L would work well too.

I had the choice between capturing only the spectrogram window, and doing this it would have been captured correctly even if covered by another window, or capture the entire application windows, with the consequent problem you mention. I chose this second route, to keep in the captured image also the addiotional info displayed outside the spectrogram area. I will investigate if there is the technical possibility to capture an entire window even if covered by some other application. About the second point you mention, are you meaning that even if you set the capture interval to, say, 900 seconds, i.e. 15 minutes, the screen gets captured every couple of minutes ? If so, it is a bug.

Obviously any 'resistive' losses with generate heat ( see the effect on metallised glaze crockery !!) but also these units cook by utilising and exciting the water-molecule resonance in food. I wonder if it possible that some materials containing small amounts of bound water (like wood) might get hot in a microwave, but not show significant effects at LF?? OR do I have to rethink my new LF loading coil fomer built on plywood cable-drum cheeks!! I do remember a number of years ago diathermy used to be a popular therapy for arthritus and for anyone living within about a mile of a hospital the 'office hours' qrm levels on HF could be quite high. I believe the 'dielectric heating' was conducted in the 400-600kHz range. I seem to remember this technique was also used in plastic fabrication for welding PVC and such materials, but I have no idea whether the same frequency range was used. One never hears anything of RFdiathermy now so perhaps this therapy has died out. I believe the machines were in the 250W to 1kW range, like power multivibrators and fed from raw rectified 50Hz power. It must have been in use before WWII as I believe many of these units were pressed into service by RV Jones and his team. I wonder whether there is any information in this are that would be of use in selecting LF low loss materials.

After allowing for the calibration error I now recognise that I had a good clear signal from Larry around midnight to 0100z . I am however finding some problems with the autosave on Argo. (Sorry Alberto, would normally have sent this direct but I havent resurrected my address-book yet.) I find the timed capture is capturing the displayed screen rather than the application window.....the later may not be possible when there is another application over the top.....but I think it is done in the program '2020'. The second point is that on 30sec dot mode the save seems to be about every couple of minutes which means that there is a vast overlap. The screen width at 30sec dots is about 17minutes. I ran out of disc space last night after saving 300 jpg files! I will trawl through these to try and find of how the signal varied during the night. Ah, also that diatribe on propagation was a personal mail to you Larry not a submission to the group, so Andy would not see that.(I can forward a copy if you would like to be 'bored' Andy!) If the after-effects of the flare run to a similar schedule as I have seen previously we should after a few days see violent deep fading on the path. This should be accompied by a significant widening of the trace seen on Andy's dopplergram. My feeling is that I would have copied a signal at 10 sec dot mode on both nights. It does seem that I probably detected a signal at 3 sec dots at at least 'T' over the 13/14th, but rejected it (and cleared the capture-files) as not being on the correct frequency, not knowing of Larry's power-problem induced shift. Its a pity CFH is still down as I have nothing to compare with to evaluate the 'progess' of the current event. LF continues to be packed with interest, which is a great thing for the Centenary of the first radio crossing of the 'pond'....thanks all.

It would be an extraordinarily bad phase comparator if it didn't begin to respond until there was a 360 degree/second error. A PLL using such a comparator could probably never achieve lock. At best, it would wander loosely around the hoped-for frequency. There does not have to be a frequency error at all for a phase comparator to output a correction voltage...only for the oscillator being stabilized to have a _tendency_ to drift away from the desired frequency, which is inevitable. Hence, once lock has been achieved, a more-or-less constant phase difference is maintained by the loop. This is not frequency error. Time is the difference between frequency and phase, as in Alan's analysis. A _frequency_ difference between two signals means the _phase_ relationship is changing continuously in the same direction over the course of time. If f1 > f2, the phase of f1 is constantly advancing relative relative to that of f2, for just as long as the frequency difference is allowed to exist. This is the condition when lock has not been achieved. When a PLL achieves lock, phase of the controlled oscillator is NOT allowed to move continuously in either direction. There may be short-term variations around the center, but no continuing trend (thus, phase lock). Without continuous phase change in a given direction, there is no frequency error relative to the reference. The remaining short term variations around the desired phase relationship are simply that: phase noise, or jitter. I hope this helps clarify the distinction. 73, John From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 2042 invoked from network); 21 Jan 2001 06:46:51 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by extortion.plus.net with SMTP; 21 Jan 2001 06:46:51 -0000 Received: (qmail 8662 invoked from network); 21 Jan 2001 06:49:35 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 21 Jan 2001 06:49:35 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14KEA8-0002Tx-00 for rsgb_lf_group-outgoing@blacksheep.org; Sun, 21 Jan 2001 06:39:40 +0000 Received: from hs-img-4.compuserve.com ([149.174.177.149] helo=sphmgaad.compuserve.com) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14KEA6-0002Ts-00 for rsgb_lf_group@blacksheep.org; Sun, 21 Jan 2001 06:39:39 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: (from mailgate@localhost) by sphmgaad.compuserve.com (8.9.3/8.9.3/SUN-1.9) id BAA14634 for rsgb_lf_group@blacksheep.org; Sun, 21 Jan 2001 01:39:26 -0500 (EST) Date: Sun, 21 Jan 2001 01:38:44 -0500 From: "'Geri' Kinzel, DK8KW" Subject: LF: Re.

The _time_ required to reach lock is indeed a function of the time constant in the feedback loop, but the total amount of possible drift is not. The way a PLL works _is_ because it drifts ever so slightly in either direction, thereby creating a DC component that is then used to bring the VCO back in the other direction. If we insert a divide-by-64 between the VCO and the PLL comparator, then the error in the comparator (phase difference) must be multiplied by 64. For simplicity's sake, let's assume that we have a phase comparator that needs a 1 Hz difference between its two inputs before it creates a DC correction signal large enough to control the VCO (not a very good phase comparator, assuredly, but just for demonstration purposes). The second phase comparator's input is the TV line frequency. The VCO operates at 1,000,000 Hz and has a divide-by-64 inserted between its output and the phase comparator. If the VCO is exactly at 1MHz, then the output of the divider is 15,625Hz, but the VCO can drift all the way to 1,000,064 Hz before the phase comparator will see a 1 Hz difference, and start reacting. 73 Andre' N4ICK From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 26867 invoked from network); 20 Jan 2001 21:24:32 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by 10.226.25.101 with SMTP; 20 Jan 2001 21:24:32 -0000 Received: (qmail 9814 invoked from network); 20 Jan 2001 21:27:59 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 20 Jan 2001 21:27:59 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14K5SU-0008Tp-00 for rsgb_lf_group-outgoing@blacksheep.org; Sat, 20 Jan 2001 21:22:02 +0000 Received: from phobos.unica.co.uk ([208.239.240.147] ident=root) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14K5SS-0008Tj-00 for rsgb_lf_group@blacksheep.org; Sat, 20 Jan 2001 21:22:01 +0000 Received: from [212.1.130.1] (helo=smtp-1.visp.telinco.net) by phobos.unica.co.uk with esmtp (Exim 3.13 #2) id 14K5SD-0000Kl-00 for rsgb_lf_group@blacksheep.org; Sat, 20 Jan 2001 16:21:45 -0500 Received: from [212.1.152.166] (helo=g4jnt) by smtp-1.visp.telinco.net with smtp (Exim 3.16 #1) id 14K4pc-00061v-00 for rsgb_lf_group@blacksheep.org; Sat, 20 Jan 2001 20:41:52 +0000 Message-ID: <002601c08322$5f071400$a69801d4@g4jnt> From: "Andrew Talbot" To: rsgb_lf_group@blacksheep.org Subject: LF: Re: Re: Loading Coils Date: Sat, 20 Jan 2001 20:48:40 -0000 MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 4.72.3110.1 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: >From G3LDO >>>From this it would appear that vector potential is a mathematical device to >simplify electromagnetic calculations rather than an entity generated by the >loading coil itself. Exactly ! Only the maths of antennas is complicated, an engineer looks at then in a much simpler way and ends up with the same results ! There are three fields generated by any electromagnetic system with a time varying component. Electric, magnetic and radiation. Vector potential is just a tool applied with Maxwell's equations to calculate the components of each of these in the three dimensions. Textbooks usually show these equations in great detail, because most students need the maths. The best textbooks don't just regurgitate the same equations repeatedly, they actually manage to explain how antennas can be made to work ! On the subject of coverings for loading coils, I have yet to find any plastic that absorbs any energy at 137kHz (although I haven't tried any of the black building materials that just may be loaded with carbon). So I was rather surprised the other day when someone mentioned that the RF had melted their antenna covering. Could it have been an arc over the surface caused by wet and dirt. It is very straightforward to find if any material intended for an insulator or for placing near loading coils is itself lossey. Just put it in a microwave cooker for a few minutes. If it gets hot or catches fire it may absorb something at 137k. I've yet to find ANY plastic that gets warm.

On the first night I set the delay so that the window scan time was 5 minutes and set the timer to take photos every 5 minutes. On the second night the same but with 10 minute intervals and the third night with 15 minute intervals. This was because Larry had announced that he would send 1 minute, 2 minute and 3 minute dashes on successive nights. However it was unclear whether this was an increasing interval or reducing and in any case it seems he actually sent 1.5 minute dashes. The first and third nights I did indeed capture dashes and have already reported to Larry the results of the first night's monitoring. The second night failed because of problems with Easygram (blank (black) photos). The third night, I saw the clearest dashes between 22.20 and 23.30 and did notice an apparent increase in frequency just after midnight. I also saw dashes between 00.24 and 00.39. In order to determine the exact frequency I copied each image into Paint Shop Pro and using the vernier scale determined the exact y-coordinate of every trace, including two frequency markers. Then using the known frequency markers, I converted these coordinates to actual frequencies. Then I saw the e-mails from Andy and Jim. I read and re-read these e-mails and no-way can I match my observations with theirs. My first thought was that my results must be innacurate. So I have spent a long time using Spectran at its highest resolution (0.031Hz) and carefully measured the position of each and every line in this part of the spectrum. Then with a table of differences calculated from the known Loran line frequencies found a very good match over 30 or so consecutive Loran lines. These told me that my receiver was out by 1.7896 Hz. Further I was able to then accurately measure two strong non-Loran lines that were visible in both Spectran and the Easygram images and found practically no difference in the accuracy of the two software packages, and very good linearity in the Easygram images. Allowing for the error in the Rx setting, It turned out that the dashes between 0024 - 0039 were at a frequency of 137788.0 +/- 0.1Hz and those between 00.24 - 00.39 were at a frequency of 137789.3 +/- 0.1Hz. So it appears that if any, it were the latter that were transmitted by Larry, but these were very weak, and it was impossible to say with any certain where dashes started and stopped. A few comments on Andy's e-mail. An accuracy of 0.05 ppm corresponds to about 0.01Hz at this frequency, but with Spectran it is not possible to measure more accurately than to 0.1 Hz. If we need to measure to this accuracy, how do we do it? What specialist hardware/software is required? I list below every trace that I could see in this part of the spectrum including all of the Loran lines seen and identified with considerable certainty.

Well now, isn't that something. Yes you sure have the signal and Phase 1 of my quest to get over the North Atlantic is now really really over! I could speed this up somewhat and we could have a QSO maybe? I still have a hearing problem I have, not seen a signal from Europe. Phase 2 of my goals is to hear a signal from Europe. Help, how do we do that? Who can I work with? When can we start? My dream was to get an LF QSO across the North Atlantic this winter season, I still want very much to do that for sure. The transmitter here continues to send its message, albeit slowly, and I wont touch a thing after seeing this .jpg file. The time has come to move to the next stage, I am waiting for proposals of transmissions from Europe that I can listen for. Jim, Congratulations, What's next?

Fig 3 in the Low Frequency Experimenter's Handbook update on http://web.ukonline.co.uk/g3ldo contained the wrong image - it was Fig 4.
I have checked all the other illustrations in Appendix 1 and they seem OK.
This has now been corrected and posted.
Many thanks to Laurie for bringing this to my attention.
 
This site will be regularly updated - some of the web pages in the LF book are already out of date!

Could I ask what 'Vector Potential' is? According to the IEE Handbook of Antenna Design: "It is convenient when working with some antennas to introduce the concept of a vector potential, A. Many problems can be solved by the use of the vector potential because the expressions for the vector potential are much simpler than those for electric and magnetic fields. The fields can always be derived from the vector potential; B = (nabla) x A" >From this it would appear that vector potential is a mathematical device to simplify electromagnetic calculations rather than an entity generated by the loading coil itself.

This failed both ways. An hour later I saw his signals with deep and rapid QSB (so that it cut some dahes in half, making them look like two dots!), during his sked with ON7YD. At 1010, Rich replied to my CQ call with an 'O' signal, giving me an 'M'. I believe this is the first G-OM QSO. It was dawn here during our early sked and I presume that the sky wave was in antiphase with the ground wave. The later QSO was mostly ground wave, though there was a little QSB. I had to retune the antenna at 0700, reducing the inductance. I thought this was due to the snow on the trees. When it got light I found that two of my cable-tie insulators had broken - presumably they had become brittle with the sub-zero temperatures we have had for a week - leaving the antenna top section supported by one insulator only. Fortunately, I had joined together the ends of the top wires to reduce corona, so all three wires were still up, but now they were arranged vertically, not horizontally. Since this will have reduced the efficiency of the antenna, I was specially pleased to make it with Rich. Pictures of OM2TW's signal and of my bent antenna wires will be posted on my web site later this weekend.

The attached file cq.jpg is edited together from 4 successive screen shots between about 0030 and 0210, and shows (C)Q DE VA(3) pretty clearly - I got fed up of editing after this, but it gives the general idea. I think this eliminates any doubt that it is the real signal. I re-checked the frequency using the Loran lines as calibration markers - it is very close to 137.7894kHz as before. On the basis of the limited experience available, the propagation fades in and out quite quickly and deeply. Often the duration of a propagation peak is only long enough for a few dots & dashes, and 1 - 2 hours seems to be an upper limit for a good signal so far. Periods last night when the signal was clearly visible were 2230- 2300, 2345 (1 dash), 0030-0220, 0430-0530, 0615-0730. These times are just estimated off the screen. After 0650, several chunks of trace were blanked out by a local QRSS signal on an adjacent frequency. I think this shows that propagation comes and goes while both ends of the path are in darkness. Weak traces of signal were visible at other times as well; the difference between 'clearly visible signal' and 'weak trace' is probably about 10-15dB. I have a continuous record of screen shots at 1/2 hour intervals for last night; I could edit them all together , but the resulting file would be too big for the reflector; if anyone has a web page they would like to put such a file on, I will put it together and send it out. Larry- as far as modifying you signal goes, the current frequency is as good as any at my QTH - your power cut was something of a blessing in disguise. The dots and spaces are fine - but the longer the transmitter spends transmitting, the more signal there is for people to detect, so I would aim at keeping spaces short.

Secondly I studied the spacing and I want to make two small changes. First, increase the spacing between bits by 100%, it is just to short at 90 seconds. Second, decrease the spacing between words from 12 minutes to 9 minutes. If you have no objection I will do that later today. For my curiosity, what time does the signal fade in and fade out?

Only managed to positively identify you at 2300z - my double-decimation software for the EVM generates a spurious line right where you were at the lowest rate so wasted about 6 hours recording yesterday. But at 3.125Hz sampling rate it just isn't there so found you eventually and left the S/W recording. During the night not a not was visible on the real time display, but at 0700z as the noise level was falling dramatically (very likely to be street lights going off) there was a particularly good set of long and short dashes. I'll leave recording for another couple of hours then post process the raw data and send you a plot. Must investigate the spurious line at the lowest sampling rate - wonder if the digital filtering process is throwing a wobbler at that rate and is alliassing in a strong signal somewhere else in the band. The spurious line moves in tune with the software Local Oscillator so alliasing looks a strong possibility.

Some 20 years ago I got the out of fashion equipment of an lf-transmitt-test-T-antenna from Pinneberg (DCF49). the plate u mentioned has been saved in my vy big junk-box until I myself built a T-antenna some month ago. isolated 40-m-radials (orignaly 80 radials in Pinneberg) increased its effect. the loading-coil 40cm in diameter was centre-positioned. u may have a look: qsl.net/dj8wx/00010.html, picture "messung.jpg" (possi u can not see it, if u use an other browser than internet explorer because my html-writing is not as good as it should be!). BTW. ..... DON`T stand on the plate .......: don`t stand on the radials too! whilst I keyed the tx outomatically measuring the fieldstrength outdoors far from the antenna I observed my chickens in the garden doing some uncontrolled somersaults. I do not use the T-antenna anymore. qso`s with OH were not possi. nowadays I got LWs of C-shortened lambd/4 length erected and qso with OH is no broblem anymore. regards Uwe/dj8wx From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 6980 invoked from network); 19 Jan 2001 20:43:11 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by 10.226.25.101 with SMTP; 19 Jan 2001 20:43:11 -0000 Received: (qmail 23143 invoked from network); 19 Jan 2001 20:46:38 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 19 Jan 2001 20:46:38 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14JiEO-0002LG-00 for rsgb_lf_group-outgoing@blacksheep.org; Fri, 19 Jan 2001 20:33:56 +0000 Received: from smtp.bellnexxia.net ([209.226.175.26] helo=tomts6-srv.bellnexxia.net) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14JiEN-0002LB-00 for rsgb_lf_group@blacksheep.org; Fri, 19 Jan 2001 20:33:55 +0000 Received: from server1 ([216.209.110.77]) by tomts6-srv.bellnexxia.net (InterMail vM.4.01.03.00 201-229-121) with SMTP id <20010119203312.LGBD11735.tomts6-srv.bellnexxia.net@server1> for ; Fri, 19 Jan 2001 15:33:12 -0500 Message-ID: <003901c08256$f3b46ca0$0a00a8c0@ThreeLakes.ca> From: "Larry Kayser" To: rsgb_lf_group@blacksheep.org References: <14126.200101191713@gemini> Subject: LF: Re: VA3LK on 137.7894 Date: Fri, 19 Jan 2001 15:22:58 -0500 MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.50.4133.2400 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Jim: > It is clearly > neccessary to check how this compares with what people see at > different QTH's before making great pronouncements on the > subject, though. Right. The signal now has a message on it, 90 second and 180 second transmit periods (3/1 ratio was for hearing cw, we hardly need to maintain that for visual work). There are space times of both 90 and 180 seconds as well, I will be confirming this later when I have time to make some notes.

The loading coil is not just a matching device, it is also a primary source of vector potential and it is the vector potential, rather than its offspring, the magnetic and electric fields, which is the fundamental source of electromagnetic radiation. It is therefore advantageous to place the coil upright at the base of the antenna. Furthermore, as a large component of the vector potential is locally concentrated in this region, it may be possible to gain a few dBs by placing an aluminium or copper plate, somewhat larger than the diameter of the solenoid, a few centimetres under the solenoid, insulated from the earth but it may be connected directly to the TX ground terminal. (It reflects the vector potental instead of allowing it to be absorbed in the terrain, but DON'T stand on the plate to adjust the solenoid whilst running at full power !!!). I appreciate that some readers may not be au fait with vector potential and perhaps its fundamental role deserves to be lightly aired in the amateur radio journals. The PROF has now spoken and he knows his subject, others take notice. I am amazed that so many other so called experienced amateurs know so little about basic radio principles and especially LF. The supposition and nonsence published on here is unbelievable it just highlights how little most know about the subject. 73, Roger, G2AJV.

I will dig out some screen shots when I get home. The most important thing regarding readability of the signal is the frequency - if the two carriers on almost exactly 137.790 turn out to be a permanent fixture, it is obviously important not to use this exact frequency; 0.6Hz low seemed to be in the clear. It is clearly neccessary to check how this compares with what people see at different QTH's before making great pronouncements on the subject, though. I will have a look at the frequency calibration again - I had to allow for around 2Hz error in the indicated frequency on the spectrogram, which is much larger than that due to the receiver, and clearly very significant for this type of use. However, drift appears to be insignificant. Measuring frequency to +/-0.1Hz in this way seems to be perfectly realistic. As far as the dot length goes, anything over about 60s should be fine for me, since the 42mHz resolution is as low as DL4YHF's Spectrum Lab goes, as far as I can tell. I think Spectran has narrower resolutions, but my aged PC doesn't seem to be able to cope with it. Spectrum Lab also has nice image recording facilities. I don't currently have any specialised DSP hardware. Some sort of distinctive pattern would be nice; but the overall pattern duration should be less than, say, 15 minutes in order to take advantage of the shorter lived propagation peaks. As far as loading coil shelters go, if made of metal then the individual parts should be connected together and to ground; but there is probably something to be said for not having a continuous screen around the coil in order to minimise eddy currents, shorted- turn effects, etc. The text books say that the distance from the surface of the coil to the screen should be at least the coil diameter, if Q is not to be significantly reduced. Steel is to be avoided due to high losses. Shielding would probably be only a benefit where the coil is located near objects with high dielectric loss - eg hedges, fences, reinforced concrete bunkers, the ground. If the loading coil is well clear of such things, screening is probably unneccessary. I will set the gear up to record tonight, using the same settings as before. let's see if it's more than a one-off!

When I put the DDS back on line the best I could do according to Bill de Carle was as follows.... "he's presently on 137,789.40 [0010 UTC]" I will try and avoid messing this setup over this weekend. I am sending continuously now, 90 second carrier with 90 second space. I am trying today to quickly implement both 90 and 270 second carriers with 90 second spaces. If I am able to get this reliable today I will put it in place by 21 utc for the rest of the weekend. If this happens I will put a short note on the RSGB reflector to that effect. > Amongst other things, there were 2 continuous traces spaced by > about 0.1Hz, virtually astride the nominal frequency. These faded in > and out in a DX fashion. Also, there was a train of dashes and > spaces of 90s +/- several seconds duration. I estimated the > frequency to be 137.7894kHz, give or take about 0.1Hz.

I was using DL4YHF's "Spectrum Lab" software, set to > 0.042Hz resolution and averaging over 2 FFTs; the SNR with these > settings was about 5-10dB, so quite clear. The real issue is, what is the absolute frequency I am on and your listening to and are they the same. I am working to get converted over to the G4JNT DDS board with my Sulzer Labs frequency standard as the reference. When that happens we will have rather excellent frequency control and resetability over here. Now, I have no real control below 1 Hz resolution, which is very good but no longer what I now need hi. > I don't know if this was VA3LK, the -0.6Hz seems rather large for > an error - perhaps Larry could confirm or deny. If they were not > VA3LK, it would be worth looking at what frequencies to avoid in > future tests. Neither the dashes or the continuous lines were > connected with the local Loran, I was able to check this by altering > the direction of the loop antenna. Well if I look at your difference of .6 Hz and Bill de Carle's mesurement of me being low by .6 Hz (after my power failure) we probably have agreement on what you were watching. My sense is I should offer you Congratulations - but maybe we should wait a bit longer for that. Your effort is appreciated so very much - I do hope that I can make my signal identifiable, I will try to get the two lengths of carrier implemented today then you can have another run at the signal over the weekend. We have had some freezing drizzle here overnight and I am going up to the remote site to see what effect that has had on the antenna current (I am recording the antenna current every 10 seconds now), if that looks manageable then I will start pushing the amplifier a little harder. My loading coil is now uncovered, wide open, as the old cover melted (a plastic laundry tub, large economy size hi) and I had to peel what was left of if off and take it away. I have a sense that I should make a new cover / small shed, to cover the loading coil. What I am waiting for is a consensus to be arrived at as to what I should use for building materials. At the moment if I have it right, I should line the inside of the cover / shed should be lined with aluminum foil, my question is do I need to bond the foil together and to ground or is it enough to just have it surrounding the coil? Regardless Jim, your effort is greatly appreciated. What else besides the two lengths of carrier can I do to make the signal more easily seen on your system?

This was located at Canedon, near South end on Sea. I think there were 3 wooden towers each around 300 ft high. These were supposed to be the first operational radar installations in the UK. We had a monkey that used to climb the towers to change the antennas when necessary for our experiments. He had a G3LD* call could it be G3LDO. It was so long ago I cannot remember his callsign, he was not employed by my company but possibly came with the antennas.

This was partially corrected by midnight where I think he shifted back upwards again - after I'd retuned 2Hz lower and gone to bed recording data without checking the signal really was there. Therefore no trace this morning - will have to check the new frequency before setting the recording tonight ! In the circumstances, the 0.6Hz error may have been genuine. Bill VE3IQ has been measuring the frequency so perhaps he can confirm the latest. If you look narrow enough there are a few signals that show drifting. Even narrower you can see these signals are spread out, more during darkness hours than in daylight. Strong evidence that they are coming from a long way away.

Subject: LF: LF Handbook update

I have posted an Addendum and Errata to The Low Frequency Experimenter's Handbook at http://web.ukonline.co.uk/g3ldo/ .
 
This information will shortly be included in the Book Shop of the RSGB web site.
 
At the last meeting at Windsor several of our group felt that it would be useful if some of the technical subjects discussed over this LF reflector might be collated and made into an indexed document (web page?). I would be happy to do this if this is what you would like to see. I have LF e-mails on file that go back to the time the LF reflector was created.
    I for one would welcome such a document, I have tried to keep my own notes but a properley collated version would be great,Go to it Peter. 73s Laurie.
Please note that my e-mail address is now

Amongst other things, there were 2 continuous traces spaced by about 0.1Hz, virtually astride the nominal frequency. These faded in and out in a DX fashion. Also, there was a train of dashes and spaces of 90s +/- several seconds duration. I estimated the frequency to be 137.7894kHz, give or take about 0.1Hz. These were also fading; there were several short periods of good reception during the night between midnight and 0700, and one long period between 0145 and 0300 when the signal was strongest. I was using DL4YHF's "Spectrum Lab" software, set to 0.042Hz resolution and averaging over 2 FFTs; the SNR with these settings was about 5-10dB, so quite clear. I don't know if this was VA3LK, the -0.6Hz seems rather large for an error - perhaps Larry could confirm or deny. If they were not VA3LK, it would be worth looking at what frequencies to avoid in future tests. Neither the dashes or the continuous lines were connected with the local Loran, I was able to check this by altering the direction of the loop antenna.

[huge cut] Peter, It looks to me like you have a local noise source. The simplest way to check this is to build a directional antenna. This could be a few tens of turns of wire about 1m in diameter, tuned by a few hundred pF, and coupled via two or three turns to the Rx. You can then do three tests: 1) Rotate the antenna to see whether your S/N improves (or even gets worse). 2) If the noise appears directional, use the antenna to get a bearing on it. 3) If you have a 12V Rx, take your receiver out in the car with the loop antenna and see whether you can get a much better S//N at locations away from home. Another thing to look at are the Loran lines. Do you see them clearly on a spectrogram? If not, you probably have a noise problem. As a guide, I can see them only when my neighbours are not playing computer games or watching their widescreeen TVs. Good luck.

It sounds interesting to me as my loading coil consists of 3 parts : - a 2.5mH coil at the top of the vertical part - a big (7mH) coil that can be tapped, at the moment I am using only 0.5mH of if (so a lot of 'useless copper' arround - a smaller coil that can be adjusted between 0.8 and 1.3mH by sliding a ferrite rod (now without the rod in in, so 0.8mH) In an attempt to be smart I placed the small coil horizontal (to avoid that the ferrite rod would 'slip away' by gravity) and the big coil vertical (to minize coupling between the 2 coils). Both coils are on a plastic box abt. 0.4m from the ground and abt. 0.3m separated. I wonder if I would gain anything if I placed both coils vertical ? Also it is attempting to try the plate under the coils, for a first try I could cover the plastic box with alu-foil (household) or is this a too thin metal layer ? If I find some time over the weekend I will try to do some tests. 73, Rik ON7YD >The loading coil is not just a matching device, it is also a primary source >of vector potential and it is the vector potential, rather than its >offspring, the magnetic and electric fields, which is the fundamental >source of electromagnetic radiation.

I have posted an Addendum and Errata to The Low Frequency Experimenter's Handbook at http://web.ukonline.co.uk/g3ldo/ .
 
This information will shortly be included in the Book Shop of the RSGB web site.
 
At the last meeting at Windsor several of our group felt that it would be useful if some of the technical subjects discussed over this LF reflector might be collated and made into an indexed document (web page?). I would be happy to do this if this is what you would like to see. I have LF e-mails on file that go back to the time the LF reflector was created.
Please note that my e-mail address is now

Hopefully with a more sensible subject line we will be alright this time. thanks G8AFN I have been investigating my receive signal to noise ratio, which seems to be about 20 to 30dB less than many people. My antenna is a 30 m longwire at about 6m average height to a Lowe 225 rx. Before I embark on a lengthy investigation I would like to confirm the signal to noise ratio people receive DCF39 at around Europe in an SSB bandwidth. After discussion with various people at the LF forum at Windsor I have. a) fitted a G3yxm pre amp b) added a 0 to 50 dB switched attenuator, 0.5dB steps. c) Rewound my in-line longwire loading coils for higher Q d) built a tapped parallel tuned circuit, similar to what is advocated for transmit purposes, to tune the loaded antenna against ground. Everything appears to resonate. These changes have resulted in about 6 to 8 dB improvement. I can now hear DJ, PA, ON and F regularly at signals very close to the noise floor. Using "spectrum" on these signals shows s/n ratios of about 6dB. It is frustrating to hear GM3YXM/p working F6CNI and find that, although I am 500km nearer, F6CNI is still only RST 239 with me. I still cannot see VE1ZZ as an identifiable callsign, even when G3XDV reports it as being at a level that was nearly audible, I am still looking at a "T" condition signal at best. Comparing the measurements of CFH taken at ON7YD suggestion before Christmas again shows my signal having a low dynamic range, compared with other stations. I have just taken Rik's reported signal to noise measurements from his top five stations of last weekend and recalculated what they would have been if they had been taken at this QRA using his system. Again I am deficient by 20 to 30dB in s/n ratio These look like clues, but something fundamental must be wrong, I do have a major manufacturing plant about 850m away and an NDB about 900m away. I cannot however invest in any enormous antenna farms nor any fancy new receivers I plan to measure DCF39 several times both day and evening over the next few days, around 0800hrs and 2000hrs using the Spectrum programme to measure signal to noise level and would appreciate any comparative measurements. I shall use my rx in USB mode, set to 137kHz, which should give a mid scale trace when spectrum is set to frequency window 1750 Hz to 1940 Hz waterfall scroll 250 msec Sample rate 11025 FFT size 16384 FFT Av 3 Log output I then plan to measure the carrier frequency which will be seen on 1830 Hz and the background noise 20 Hz higher. If you are able to help please e-mail your measurements, together time and with QRA, direct to avoid cluttering up the reflector. many thanks Peter Cleall G8AFN From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 13663 invoked from network); 18 Jan 2001 21:44:15 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by extortion.plus.net with SMTP; 18 Jan 2001 21:44:15 -0000 Received: (qmail 8060 invoked from network); 18 Jan 2001 21:46:59 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 18 Jan 2001 21:46:59 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14JMkb-0003vU-00 for rsgb_lf_group-outgoing@blacksheep.org; Thu, 18 Jan 2001 21:37:45 +0000 Received: from amersham.mail.uk.easynet.net ([195.40.1.45]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14JMkb-0003vP-00 for rsgb_lf_group@blacksheep.org; Thu, 18 Jan 2001 21:37:45 +0000 Received: from ericadodd (tnt-3-170.easynet.co.uk [195.40.202.170]) by amersham.mail.uk.easynet.net (Postfix) with SMTP id 2A016176EB for ; Thu, 18 Jan 2001 21:37:07 +0000 (GMT) Message-ID: <002f01c08197$075f3a20$aaca28c3@ericadodd> From: "g3ldo" To: rsgb_lf_group@blacksheep.org References: <5.0.2.1.2.20010115093244.00a18b40@mail.pncl.co.uk> Subject: Re: LF: coil screening Date: Thu, 18 Jan 2001 21:35:47 -0000 MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.50.4522.1200 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Further to Walters e-mail: > Gamal says it all.

The loading coil is not just a matching device, it is also a primary source of vector potential and it is the vector potential, rather than its offspring, the magnetic and electric fields, which is the fundamental source of electromagnetic radiation. It is therefore advantageous to place the coil upright at the base of the antenna. Furthermore, as a large component of the vector potential is locally concentrated in this region, it may be possible to gain a few dBs by placing an aluminium or copper plate, somewhat larger than the diameter of the solenoid, a few centimetres under the solenoid, insulated from the earth but it may be connected directly to the TX ground terminal. (It reflects the vector potental instead of allowing it to be absorbed in the terrain, but DON'T stand on the plate to adjust the solenoid whilst running at full power !!!). I appreciate that some readers may not be au fait with vector potential and perhaps its fundamental role deserves to be lightly aired in the amateur radio journals. 73, Roger, G2AJV.

I am not shure whether this calculation is applicable to a loading coil. The coil in a mobile antenna for the HF bands is considered to radiate as a linear conductor with a length equal to the length of the coil. I think this could also be the case for a loading coil at LF. So if the coil is 1 metre long (high) with its axis vertical it acts as a 1 m long vertical antenna and when at the bottom of a vertical antenna it makes the radiator 1 m longer. 73, Dick, PA0SE From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 14426 invoked from network); 18 Jan 2001 19:43:18 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by 10.226.25.101 with SMTP; 18 Jan 2001 19:43:18 -0000 Received: (qmail 18707 invoked from network); 18 Jan 2001 19:46:43 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 18 Jan 2001 19:46:43 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14JKvD-0003Ef-00 for rsgb_lf_group-outgoing@blacksheep.org; Thu, 18 Jan 2001 19:40:35 +0000 Received: from imo-d07.mx.aol.com ([205.188.157.39]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14JKvC-0003EW-00 for rsgb_lf_group@blacksheep.org; Thu, 18 Jan 2001 19:40:34 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from WarmSpgs@aol.com by imo-d07.mx.aol.com (mail_out_v29.5.) id l.c.101432bd (16788) for ; Thu, 18 Jan 2001 14:39:44 -0500 (EST) From: WarmSpgs@aol.com Message-ID: Date: Thu, 18 Jan 2001 14:39:44 EST Subject: Re: LF: New to the list To: rsgb_lf_group@blacksheep.org MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII; format=flowed Content-Transfer-Encoding: 8bit X-Mailer: AOL 4.0 for Windows 95 sub 120 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Welcome, Marcus!

Most of us no longer have access to the older data; and it was generated using much higher power levels, which could potentially obscure interesting effects that we might be able to exploit. 73, John From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 20940 invoked from network); 18 Jan 2001 18:35:00 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by excalibur.plus.net with SMTP; 18 Jan 2001 18:35:00 -0000 Received: (qmail 1722 invoked from network); 18 Jan 2001 18:29:23 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 18 Jan 2001 18:29:23 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14JJid-0002pj-00 for rsgb_lf_group-outgoing@blacksheep.org; Thu, 18 Jan 2001 18:23:31 +0000 Received: from [212.159.14.227] (helo=warrior-outbound.servers.plus.net) by post.thorcom.com with smtp (Exim 3.16 #1) id 14JJic-0002pZ-00 for rsgb_lf_group@blacksheep.org; Thu, 18 Jan 2001 18:23:30 +0000 Received: (qmail 25114 invoked from network); 18 Jan 2001 18:22:47 -0000 Received: from unknown (HELO picks) (212.159.47.199) by warrior with SMTP; 18 Jan 2001 18:22:47 -0000 Message-ID: <002c01c0817c$d026b7a0$c72f9fd4@f9.net.uk> From: "Dave" To: rsgb_lf_group@blacksheep.org References: <3.0.1.16.20010118142719.33cf5a3e@mail.cc.kuleuven.ac.be> Subject: Re: LF: Caged Coils Date: Thu, 18 Jan 2001 18:31:02 -0000 MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.00.2615.200 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Mal, Rick etc. I am an amateur amateur, I experiment!

If I have it right your talking about white "wet stuff" that was barely frozen that you recently had in the UK? Yes that is "wet stuff", what we call spring, summer and fall over here hi. We have four seasons here, Seriously cold and lots of snow, wet soggy and cool with big snow storms not forecasted, occasionally warm with snow flurries and preparing for seriously cold with daily white outs. > What frequencies were used at MF ? The lowest would be around 1.7 mHz up to 12 mHz . I mostly worked CW and the lower frequencies. We did have one channel at 1.7 mHz CW to Greenland that worked especially well.

In that case I won't try dangling a long wire down from Portsdown Hill. If I wanted to install an (amateur) LF antenna at the works QTH (just an idea for a low power beacon) the very poor ground is in complete contrast to the clay in my garden at home. Something else is needed as a radial system is not viable and earth rods absolutely useless in chalk. . As for other antennas, Every so often thoughts return to big loops. I still feel sure that at a certain dimension there will come a point where a loop is as efficient as a vertical wire for a given TOTAL amount of copper - it will be quite big but G2AJV was very pro-loop in the early 73kHz days and he had a one of 100s of m^2 Certainly for a back garden sized antenna we can't do better than a vertical even when ground conductivity is poor, but for people who have access to orchards and paddocks......... As the efficiency of a loop goes up at a rate somewhere between the third and fourth power of its linear dimensions (Loop radiation resistance varies as area ^2 = dimension ^4 against R loss proportional to dimensions), and wire antennas roughly as length^2, there ought to be a point where the graphs cross and loops become more efficient. But I don't know how to model both in a way that equalises the amount of copper which is the parameter we probably should keep constant. And then there are other effects such as ground conductivity (poor ground favours loops), proximity of trees (local trees again favour loops) to be taken into account as well. Of course, a superconducting loop could have very high efficiency, but at a bandwidth that makes Visual CW at days per dot mandatory :-) Andy G4JNT > Depressing as it may be, Marconi got it right 100 years ago and we > have failed to improve on his findings.

I tried something like this in GW in the early days of 73khz but it was very poor. Rock may be a poor conductor but it still appears to absorb most of the RF. And it wasn't just that my antenna was horizontal as in fact it went up a steep hillside at some 30 degrees. I tried it again when trying to work MI0AYZ as a deperate attempt when my kite failed to fly - it was still poor. Worked fine on receive, though. Depressing as it may be, Marconi got it right 100 years ago and we have failed to improve on his findings. There must be another magic antenna out there somewhere but that isn't it.

Many years ago I did read somwhere an article about horizontal dipoles used in the desert that were just laying on the sand. But I cannot remember where I did read it nor what frequecies were involved. Since the polarization will be horizontal the antenna should work better the poorer the ground is. Assuming that even on the poorest ground the 'virtual mirror' will be only a fraction of the wavelength these antenna will radiate at rather high angles compared to the 'traditional' antennas. This fact and the horizontal polarization make me believe that it will be no good for surface wave propagation (for that reason probably the 'commercials' never tried it), but it might be a good sky wave launcher. Only way to find out if (and how) it works is to try it ... 73, Rik ON7YD At 11:31 18/01/01 -0000, G4JNT wrote: >A new subject now ..... > >Someone must have already tried this, but how effective would a (say) >100m long dipole laid down a chalk hill be ? >Isn't limestone also the same material as chalk, Are there any CREG >members reading this who know about conductivity of rocks? >Chalk is a very poor conductor, even when wet.

The radiation resistance of a multiturn loop is : Rs = 31200 x (n x F / L^2)^2 where Rs = radiation resistance, n = number of turns, F = loop area, L = wavelength. For my loadingcoil n = 120 and F = 0.04m^2, so at a wavelength of 2200m the radiation resistance will be about 30 nano-Ohm. Estimated radiation resistance of my inverted-L antenna is about 40 milli-Ohm. Shielding the coil (done properly - avoiding short circuit turns) would make my signal 0.000003dB weaker. 73, Rik ON7YD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 27164 invoked from network); 18 Jan 2001 12:16:29 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by extortion.plus.net with SMTP; 18 Jan 2001 12:16:29 -0000 Received: (qmail 4276 invoked from network); 18 Jan 2001 12:19:13 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 18 Jan 2001 12:19:13 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14JDvM-0000c0-00 for rsgb_lf_group-outgoing@blacksheep.org; Thu, 18 Jan 2001 12:12:16 +0000 Received: from gigi.excite.com ([199.172.152.110]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14JDv9-0000br-00 for rsgb_lf_group@blacksheep.org; Thu, 18 Jan 2001 12:12:03 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from chilly.excite.com ([199.172.153.77]) by gigi.excite.com (InterMail vM.4.01.02.39 201-229-119-122) with ESMTP id <20010118121118.FJAG13981.gigi.excite.com@chilly.excite.com> for ; Thu, 18 Jan 2001 04:11:18 -0800 Message-ID: <16879148.979819878979.JavaMail.imail@chilly.excite.com> Date: Thu, 18 Jan 2001 04:11:15 -0800 (PST) From: "john sexton" To: rsgb_lf_group@blacksheep.org Subject: Re: LF: In-Reply-To: <29BDD4F529FCD311B631009027357C4E01ECA01F@btss103a.swh.sk> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 8bit X-Mailer: Excite Inbox X-Sender-Ip: 213.104.153.33 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Hi Rik, I see this line too but it is very weak for me, so must be somewhere nearer you guys.

A new subject now .....
 
Someone must have already tried this, but how effective would a (say) 100m long dipole laid down a chalk hill be ?
Isn't limestone also the same material as chalk,   Are there any CREG members reading this who know about conductivity of rocks?
Chalk is a very poor conductor, even when wet.   A 4m earthing rod driven into the top of Portsdown Hill on the South coast of the UK in an attempt to make an RF ground  measured 120 ohms to mains Earth - attempt abandoned in favour of a dipole !
 
There are plenty of chalk hills of this sort of height, and the amount of wire needed - 500m perhaps - means the radiation resistance will rise to an acceptable figure to reduce copper loss.

To me, the idea of being able to actually see ionospheric effects on skywave signals at LF, which to my knowledge have never before been characterised, is more exciting than being the first to make a two way QSO. Previously, as Walter said, skywave was just a nuisance that they tried to eliminate. If two operators at each end happen to be awake and operating at the right time that an ionospheric bubble forms (or whatever is up there) with a high power transmitter and big antenna, then they'll make the QSO. But no one will know the mechanism by which the QSO was achieved, apart from brute force, until it has happened several times and been mapped out. Meanwhile we will continue with proper controlled scientific experiments at low powers where Larry's signal appears to be receivable 100% of the time. Then with the knowledge we can attack the medium in a controlled way. Anyone can join in if they have suitable receiving hardware - all it wants is a willingness to build and understand new and modern hardware; a quality sadly lacking in many of today's radio amateurs. Particularly unfortunate as there is a huge range of devices that make homebrewing of quite advanced equipment trivial - and finding the necessary data is not even the trial it once was, everything is available on line.

On a commercial transmitting site there are reasons for caging the loading coil but it does not include enhanching the rf intensitity of the radiated signal, in fact the opposite. The commercial operators place the coil at a convenient place for tuning, then have to cage it to protect staff working in the vicinity. They have other consideration depending on the tx site like weather variations causing detuning and they go for stability and sacrifice some efficiency. These factors do not normally concern the radio amateur on LF because of the low power involved. The antenna loading coil is an integeral part of the actual antenna system and needs to be placed UNCAGED under the antenna vertical for maximum efficiency. As I said before the loading coil unshielded at the base of a short vertical also contributes to the radiating efficiency, and if you can manage a part helical wound vertical that is even better. Any deviation from this method only degrades the antenna system, regardless of what Marconi, Decca or Polmvhetztc said.

There are several signals a few Hz away from 137790Hz. In a 2.5Hz bandwidth I clearly saw the following during Tuesday nights test : 1) Clean carrier at 137789.10 about 15 dB above noise in 0.015Hz bandwidth 2) Larry's signal at 137789.89, sometimes smeared out to as wide as 0.05 Hz during the period around 2300z to 0300z - Due to Doppler shifts and multipath ? - Then cleaned up and got stronger at 0500z. This frequency measurement agrees with VE2IQ measuring locally. 3) 0200z to 0600z A signal showing the same or even more smearing at 137790.09 - a long distance transmission ? 4) Fading or pulsed carrier that appeared at 0500z on 137790.35 5) A pulsed carrier (variable switching periods of several minutes) at 137790.36 (not the same as above !) 6) A pulsed carrier (variable switching periods of several minutes) at 137790.7 2) to 6) were all about 2 - 6dB above noise Outside this bandwidth, but visible from Wednesday's monitoring, a strong carrier at 137791.5 approx (didn't bother measuring it ) about 40 - 50dB above noise in 0.04Hz bandwidth. This is presumably what others are seeing and mistaking for Larry !! He is at least 30dB weaker that this. For last night's transmission I recorded raw data for a 6.25Hz bandwidth at a sampling rate of 7.8Hz, any interesting results from post analysis will follow........ For anyone else wanting to perform similar scientific measurements - Spectran should just about cope, but you will need to calibrate your soundcard sampling rate to at least 1ppm accuracy and receiver to 0.05ppm by receiving a standard frequency transmission such as MSF. And allow several hours for warm up drift. It's rather satisfying that I can see something that looks like ionospheric distortion on the signal. One aim now will be to post-process the raw data and filter out all the other lines as listed above. It would be interesting to make an "Ultra Dopplergram" to a resolution of 0.001Hz or lower over many hours to separate out the separate signals that would make up the multipath.

I told the computer how to do it once, and I suspect it has not forgotten how to do it. At 50 WPM or faster, I forget what speed I told it to do the ID, it gets done quickly when needed. I am not sure if our Radio Inspectors have to know Morse any more so it might be a waste of time, but since only the Radio Inspector and I have to agree that it is done I am surprised the subject is of issue here. If I crank the speed up high enough it wont bother the DSP any........ > That should ensure a wide audience! The goal is not a wide audience! The goal is a two way LF QSO over the North Atlantic. A new train had left the station, some will jump on board, some will choose not to jump on board, some wont know the train has left and they will never find out.

I seem to recall a BBC program some years ago on this subject - I think QRM was one of the main reasons the scheme was abandoned. Also, if somebody in the neigborhood was, say, folding their newspaper, the unfortunate operator would have his eardrums ruptured. Another problem was that, with sound being of the order of a million times slower than radio waves, the warning did not arrive that much faster than the planes themselves. Over a path of 50km, it would take about 5 minutes for the signal to go both ways - perhaps QRSS would be a better bet... I once saw a smaller version of this, I think in the Science Museum in London. It had a couple of dishes set up on opposite sides of the hall. It was quite an uncanny effect when you were at the focus of one dish - it sounded as if the person at the other end was right beside you.

Since the image is too large for the reflector, I shall post it on my web site, www.g4cnn.f2s.com. Hi Larry, I used Easygram last night from 20.00 to 03.00 making snaps every 5 minutes and it does look as though I have captured your transmission. It was best around 00.15 and continued to be visible in snaps until 00.30 when it faded out again. I set the delay so that it took almost exactly 5 minutes to write an image from left to right of the window. That way I miss nothing. I have spent all morning with Excel calculating the exact frequency and identifying every line in the picture. Most are Loran lines but a couple are either European stations or perhaps spuria. The line in the middle which I believe is your signal is clear of other lines and appears to be almost exactly on frequency. The error of about 0.5 Hz, is I am sure a result of innacuracy in measuring the exact position of the line in the recorded image. Unfortunately I am having some problems with Easygram, it seems to turn off the sound card for periods up to an hour and then back on again, rather randomly, so a lot of the snaps are blank, but it is the only program I have that allows me to do this sort of recording while I am in bed. I shall discuss the fault with the author, Petr, and hopefully have it sorted soon. Looking forward to tonight's trial. I assume last night was 1 minute dashes and tonight will be 2 minute dashes. The image is attached. I found that Zipping it practically made no difference to the size, so haven't bothered. 73, John, G4CNN _______________________________________________________ Send a cool gift with your E-Card http://www.bluemountain.com/giftcenter/ From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 831 invoked from network); 17 Jan 2001 12:54:57 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by 10.226.25.101 with SMTP; 17 Jan 2001 12:54:57 -0000 Received: (qmail 21447 invoked from network); 17 Jan 2001 12:58:23 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 17 Jan 2001 12:58:23 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14Irz7-00026k-00 for rsgb_lf_group-outgoing@blacksheep.org; Wed, 17 Jan 2001 12:46:41 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from [213.2.16.106] (helo=rsgb.org.uk) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14Irz3-00026f-00 for rsgb_lf_group@blacksheep.org; Wed, 17 Jan 2001 12:46:37 +0000 Received: from miked by rsgb.org.uk with SMTP (MDaemon.v2.8.7.5.R) for ; Wed, 17 Jan 2001 12:36:11 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 From: "Mike Dennison" To: rsgb_lf_group@blacksheep.org Date: Wed, 17 Jan 2001 12:36:08 -0000 MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII; format=flowed Content-Transfer-Encoding: 8bit Subject: LF: 9kHz DX with no power supply!

It is fascinating. Briefly this describes huge concrete acoustic dishes built in the 1920s, aimed at listening for enemy airplanes up to 25 miles away. An artist is building new dishes for Folkestone (G) and Boulogne (F). She claims that you will not only hear the sea but also be able to talk to the person who is using the other dish 50km away. Hard to believe that the QRM from the sea won't be a huge problem as this is not even line of sight. As my wife's mother lives in Folkestone, I will try it when it is built, and report back. So, if you fancy breaking the 9kHz record without spending a penny on electricty, simply build an acoustic dish!

Why not send > your callsign QRSS for a positive identification. I understand your commitment to Visual CW, I wish you well in it, but it is not my commitment and not my interest. The transmissions for the next few days are of a precise known dash duration that will change each day. The purpose is so that advanced DSP tools can have a good look for the signal way way down in the mud. The positive identification is in the recognition of the consistent length (for the day) of the dash. If I have it right, 50% of the signals from North American activity on 136 kHz are sending Visual CW, that is surely enough for those with an interest in Visual CW. My choice is to move onwards, not to suggest that there is anything wrong with Visual CW, but to move to new techniques and processes. My LF goal is and remains to have the first two way QSO across the North Atlantic. After that is a one way LF from here to ZL/VK. Repeating the Visual CW process on a going forward basis doing the same that has been done is not an option I am prepared to support. In my opinion the probability of have a visual CW two way QSO from here in Eastern Ontario to Europe this year is not likely. I am also not prepared to put in the "scope" hours to make such an achievement happen. My sense is that the QSO can be done with advanced DSP, I am following that route almost exclusively from now on. I will support special events whole heartedly, but my focus is DSP on LF as the way to achieve my goals. I also operate HF CW on a regular basis. My main operating interest is HF CW and I am an active member of both the British FOC CW club as well as a member of the more irreverent CFO, Chicken Fat Operators club on this side of the Atlantic. I hope this makes it clear what are my intentions and my direction. My intention with this message is to remove any potential for angst by those who do not share the same vision and direction that I have.

In very short order, despite long success with polypropelene ropes for keeping wires away from bushes and towers etc., the Decca cooked all the ropes into shorter pieces of rope with burn marks. Yes the Decca will surely take a dead short on its output. It doesn't even grunt harder, it just sits there and pretends it is working. Three fast trips out to the remote site - on the third trip I went out to the loading coil site and saw all the yellow pieces of rope laying in the snow. All this happens because today I got another ampere out of the unit and into the antenna.

I have submitted the following story to the RSGB newsdesk (my colleagues in the next office) for use on the weekly GB2RS news bulletin. Please let me know urgently if I have anything wrong. ---------------- Over the weekend of the 12th to the 14th of January, stations in Canada, the USA and Europe attempted the first two-way transatlantic contact on the 136kHz band. Although the two-way was not successful, the one-way distance record was broken in both directions. VE1ZZ received OK1FIG at distance of 5694km, and SWL NL9222 received VA3LK at a world record distance of 5726km. G0MRF, who was the first station to cross the Atlantic on 136kHz, put up his antenna on an apartment block on the Sunday, but was hampered by the high static levels and poor conditions that made that day's tests a washout at both ends. On the Saturday, several UK stations received good signals from Canada but MM0ALM was the only European, apart from OK1FIG, to make it in the opposite direction. Extremely slow Morse was used by all stations to enable signals to be decoded well below the noise level. VE1ZZ was occasionally audible in the UK but the strength was not sufficient to read normal speed Morse. The USA team, operating from North Carolina, heard a number of LF stations including VE1ZZ, but no Europeans. ------------------------ Mike, G3XDV (IO91VT) http://www.lf.thersgb.net From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 6534 invoked from network); 15 Jan 2001 22:55:30 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by extortion.plus.net with SMTP; 15 Jan 2001 22:55:30 -0000 Received: (qmail 6500 invoked from network); 15 Jan 2001 22:58:12 -0000 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 15 Jan 2001 22:58:12 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14IIT4-0000ef-00 for rsgb_lf_group-outgoing@blacksheep.org; Mon, 15 Jan 2001 22:51:14 +0000 Received: from anchor-post-33.mail.demon.net ([194.217.242.91]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14IIT3-0000ea-00 for rsgb_lf_group@blacksheep.org; Mon, 15 Jan 2001 22:51:13 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from pickmere.demon.co.uk ([158.152.117.143]) by anchor-post-33.mail.demon.net with smtp (Exim 2.12 #1) id 14IISr-000NGz-0X for rsgb_lf_group@blacksheep.org; Mon, 15 Jan 2001 22:51:03 +0000 Message-ID: Date: Mon, 15 Jan 2001 19:03:24 +0000 To: rsgb_lf_group@blacksheep.org From: "M.J.Powell" Subject: Re: LF: RE: Rugby Loading Coils References: <65AECDF1F89AD411900400508BFC869F0D7509@pdw-mail-1.dera.gov.uk> <65AECDF1F89AD411900400508BFC869F0D7509@pdw-mail-1.dera.gov.uk> <5.0.2.1.2.20010112082156.00a05c20@mail.pncl.co.uk> In-reply-to: <5.0.2.1.2.20010112082156.00a05c20@mail.pncl.co.uk> MIME-Version: 1.0 X-Mailer: Turnpike Integrated Version 4.02 S Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: In message <5.0.2.1.2.20010112082156.00a05c20@mail.pncl.co.uk>, Walter Blanchard writes >At 20:42 11/01/01 Thursday, G3IJE wrote: > >>................................. if they can list a WW II radar mast then >>this is >>even more historical....................... > > >Sorry this is off-subject, but which radar mast is that please?

Perhaps it is time for customers to quit buying into every new idea that comes out of the computer and software companies, stick with a version that works for us, and thereby give the smaller software developers a chance to catch up with the big guys and provide some real alternatives! 73, John From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 4672 invoked from network); 15 Jan 2001 18:38:26 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by excalibur.plus.net with SMTP; 15 Jan 2001 18:38:26 -0000 Received: (qmail 9151 invoked from network); 15 Jan 2001 18:32:53 -0000 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 15 Jan 2001 18:32:53 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14IEIt-0007xc-00 for rsgb_lf_group-outgoing@blacksheep.org; Mon, 15 Jan 2001 18:24:27 +0000 Received: from anchor-post-32.mail.demon.net ([194.217.242.90]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14IEIs-0007xX-00 for rsgb_lf_group@blacksheep.org; Mon, 15 Jan 2001 18:24:26 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from pickmere.demon.co.uk ([158.152.117.143]) by anchor-post-32.mail.demon.net with smtp (Exim 2.12 #1) id 14IEId-0000jD-0W for rsgb_lf_group@blacksheep.org; Mon, 15 Jan 2001 18:24:11 +0000 Message-ID: <1Gs$LAAhOzY6EwnC@pickmere.demon.co.uk> Date: Mon, 15 Jan 2001 17:30:09 +0000 To: rsgb_lf_group@blacksheep.org From: "M.J.Powell" Subject: Re: LF: re Rugby site References: <002301c07c2c$b7247940$fb9601d5@default> In-reply-to: <002301c07c2c$b7247940$fb9601d5@default> MIME-Version: 1.0 X-Mailer: Turnpike Integrated Version 4.02 S Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: In message <002301c07c2c$b7247940$fb9601d5@default>, Alan Melia writes >Hi All, the 2 inch 'water-pipe' coil that Andy refers to would have been >installed in the mid 1960s when the transmission was 'phase stabilised' (at >least thats what the guys who were responsible for it at PO Dollis Hill >called it) I have never seen that bit.

My radio room is an upstairs bedroom and the LF antenna top loading wires pass directly above, attached to the apex of the roof probably 3-4m above the shack ceiling. While transmitting, every time I brushed against a piece of earthed metal I could feel a slight RF burn or shock, not detectable if the metal was grabbed but unpleasent if touched gently with an arm or similar. The weather was extremally dry and the antenna load resistance the lowest it has been for some time, which may be why I have not seen this before with the new 600 W amplifier. The field is probably in the region of 2 - 3 kV/m here. Occasionally the fluorescent tube on the ceiling will light faintly with the RF - this was much more noticeable and spectacular on an older fitting that was not on an earthed metal box but left the tube in free space connected to its starter remotely - on 73kHz that would flash brightly with CW keying to the extent that I had to leave the light on when beaconing at night !! So, if you are sitting in the fields generated by 1kW transmitters be prepared for a few minor burns / shocks. And don't ever touch the hot antenna feed, I guess that would give a third degree burn if the arc is maintained for more than a few seconds To once demonstrate the plasma arc, I struck one from a (well insulated) screwdriver and managed to draw it out to 50mm, burning the PTFE wire insulation and marking the screwdriver tip - and that was only on 150W of 73kHz !

In the UK the prevailing dampness made it impossible to maintain tuning or coil "Q" and you would get corona all over the place. He warns against using ordinary soda-lime window glass for insulation - it is very lossy and will shatter, the only glass that will stand up is Pyrex-type. He says an excellent insulator he used many times was the largest Pyrex baking dish he could find with a hole bored in the bottom for the feeder. Also, ordinary plastic ropes (terylene, nylon, polypropylene etc) will melt. Either use steel wires broken up by many insulators or (expensively) sleeved Kevlar rope. And if you're going to run real power you MUST put in voltage limiters ! He thinks the fire in Dave's hut was probably caused by the plastic walls breaking down, getting hot and catching fire. I could probably persuade him to come along to Beaumont for the next conference and give us a talk if you like. Walter G3JKV.

Friday : Rather poor condx, but fortunately also QRM level was low. VE1ZZ was copied 'M' here at several moments during the evening (between 20 and 23 UT, went to bed afterward - a lot to do on saturday). Of course many strong signals between 135.9 and 136.0, I did a kind of SNR measurements using SpexLab at 0.3Hz bandwidth (comparing signals to background noise). The 'top 5' was (arround 22 UT) : OK1FIG = 58dB MM0ALM = 45dB M0BMU = 42dB G3AQC = 40dB G3YXM = 38dB BTW : I had to insert 50dB attenuation to avoid that Petr triggered the AGC. Further I took notice of some rather strong 'lines' close to 136.5 (SNR at 0.04Hz BW between brackets) : 492.2 (12db), 496.0 (4dB), 498.8 (22dB), 501.7 (7dB), 502.5 (18dB), 503.3 (15dB), 504.6 (10dB) There seems to be much more of this rubish down the band, compared to the 137.7kHz segment. It would be interesting to know which of these lines are local QRM and which are 'DX'. Another reason to move up to 137.7 : some stations were very active just above 136.5 in normal CW on friday night. Fortunately only 1 of them was strong enough to affect VE1ZZ's signal and his activity was limited. At least 2 of this stations read the reflector (and thus were informed about the VE1ZZ activity), so could this be interpreted as a 'warning' against QRS activity down in the band ? Saturday : Turned on the RX at 19.50 UT, the s-meter was dancing at S9, due to static. As could be expected no sign of VE1ZZ. Static kept far too bad to copy any weak signal at 0.3Hz bandwidth, so I decided to have a look at VE1ZZ at 0.04Hz bandwidth. Of course this is far too narrow to copy the dashes and dots but on some occasions I could see a trace appearing on the expected frequency at the beginning of the transmitting period and disapearing 10 minutes later. One time I could even see that it got fussy after 10 minutes (when they started normal CW ?). I also could notice a very small 'wobbeling' on the signal, going up and down about 0.1Hz over the 10 minute period. 73, Rik ON7YD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 21365 invoked from network); 15 Jan 2001 10:32:08 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by 10.226.25.101 with SMTP; 15 Jan 2001 10:32:08 -0000 Received: (qmail 9327 invoked from network); 15 Jan 2001 10:35:33 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 15 Jan 2001 10:35:33 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14I6sS-0005e4-00 for rsgb_lf_group-outgoing@blacksheep.org; Mon, 15 Jan 2001 10:28:40 +0000 Received: from [194.73.73.176] (helo=protactinium) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14I6sR-0005dz-00 for rsgb_lf_group@blacksheep.org; Mon, 15 Jan 2001 10:28:39 +0000 Received: from [62.7.101.151] (helo=default) by protactinium with smtp (Exim 3.03 #83) id 14I6sF-0007XM-00 for rsgb_lf_group@blacksheep.org; Mon, 15 Jan 2001 10:28:27 +0000 Message-ID: <000901c07ede$1951bac0$9765073e@default> From: "Alan Melia" To: rsgb_lf_group@blacksheep.org Subject: LF: VE1ZZ Sun/Mon Date: Mon, 15 Jan 2001 10:29:02 -0000 MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 4.72.3110.5 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Hi all.

It was impossible to keep the Decca coils tuned accurately and maintain phase constancy without the copper screening. Even then there had to be an automatic re-tuning device for when nearby lightning strikes made the coils jump. It was driven by a small electric motor and a belt/pulley arrangement that moved a little subsidiary coil back and forth a few inches. Occasionally there was a direct lightning strike on the antenna usually resulting in the belt jumping off the pulleys and a panic callout for the duty engineer. And for Bob, VE7BS - no, there was nothing in the hut except the loading coils - it was only about 5 x 5 metres. Walter G3JKV.

After a few months of QRT on 136, I build a new antenna, but in my home QTH (to prevent thieves activities). It's 137m long wire, maximum about 25m above the ground. Friday afternoon was all ready to be on the air. But only without my defect power amplifier. So I tried it with QRP with some friends around 50km of my QTH. Reports from 579 to NIL. So, I tried to call Petr OK1FIG (he was S9+40dB) with 2 Watts output only on normal CW. 3th call and OK1FIG is in the log (599/529). Oh boy...that's QRPP....280km with 2 Watts. That's all for a saturday. I was very busy with my sons. On sunday (during a breakfast) I build an "sparrow nest" power amplifier with about 50W output. Sunday afternoon was an beacon on the air for about 5 hours (on 136.3 and for a short time on 137.5) and I got reports from OM, YO, OK and HA. I'll put it again on the air this afternoon untill friday afternoon. It will run with 50W and normal CW, 24 hours a day on 136.3 kHz. Only for test purposes. If you will hear me, please send me an E-mail or spot me in the cluster. Thank you very much. Best regards and see you on LF with a bit higher power. 73 de Rich OM2TW From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 20829 invoked from network); 15 Jan 2001 07:09:25 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by 10.226.25.101 with SMTP; 15 Jan 2001 07:09:25 -0000 Received: (qmail 1163 invoked from network); 15 Jan 2001 07:12:49 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 15 Jan 2001 07:12:49 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14I3bj-0004j4-00 for rsgb_lf_group-outgoing@blacksheep.org; Mon, 15 Jan 2001 06:59:11 +0000 Received: from mail2.hamilton-standard.com ([153.4.57.12]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14I3bh-0004iz-00 for rsgb_lf_group@blacksheep.org; Mon, 15 Jan 2001 06:59:10 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from curly.hsd.utc.com by mail2.hamilton-standard.com; (8.9.1/) id CAA12593; Mon, 15 Jan 2001 02:02:15 -0500 (EST) Received: from umrsvr.hsd.utc.com by curly.hsd.utc.com; (8.9.0/) id BAA28404; Mon, 15 Jan 2001 01:58:27 -0500 (EST) Received: from nmex01nt.hsd.utc.com by umrsvr.hsd.utc.com; (8.9.0/) id BAA15614; Mon, 15 Jan 2001 01:54:16 -0500 (EST) Received: by nmex01nt.hsd.utc.com with Internet Mail Service (5.5.2650.21) id ; Mon, 15 Jan 2001 07:48:26 +0100 Message-ID: From: "Soegiono, Gamal" To: rsgb_lf_group@blacksheep.org Subject: LF: coil screening Date: Mon, 15 Jan 2001 07:48:16 +0100 X-Mailer: Internet Mail Service (5.5.2650.21) Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Content-type: text/plain; charset=windows-1252; format=flowed MIME-Version: 1.0 Content-transfer-encoding: 8bit Hello Lech and all lining the antenna tuning house with screening is about standard in LF/MF transmitter installations. Screening of all six sides serves several tasks: provide short and low impedance return current paths for the matching circuit. prevent EM fields couple into the coils and interconnecting wiring (inch class copper tubing). prevent losses from humid building material when exposed to high EM fields associated with the matching circuits provide protection for humans from effects in high EM fields associated with the matching circuits Some antenna tunng houses are lined with aluminium sheets (DHO38 installation in Ramsloh, 23k4), most others are lined with cooper sheet material. Copper sheets have the benefit that the material is electrical compatible with copper conductors and can be soldered for good electrical continuity. Aluminium sheets are cheaper by themselves but need surface treatment (Alodine treatment) for making good electrical contacts. If it where just the inductors, which need screening, then a minimum spacing from coils to screen equivalent to coil diameter should be provided for both, to keep edy-currents in the screening under control, and to keep capacity to ground under control. Lining the whole building serves all tasks outlined above at moderate cost and optimum performance. > -----Original Message----- > From: Lech Laszkiewicz [SMTP:Lechlaski@btinternet.com] > Sent: Sunday, January 14, 2001 8:49 PM > To: RSGB LF Reflector > Subject: LF: coil screening/TA test/ DECCA TRANSISTORS > > I wonder why a very highly professional designers of the Decca system went > to the expense and complexity of copper sheet screening of the interior of > their complete buildings containing the antenna tunung/loading coils. > They > seem to have obtained considerable advantages doing so, inspite of the > dissertation of a certain homegrown "Guru".

Basically, this scheme acts as a harmonic mixer driven by 2x 128.93 kHz (=DCF49), linearly converting the DCF42 noise band around 121.3 up to 136.5 kHz. The gif is a circuit diagram, and I could send pictures and spectra directly. The first tests showed a significant improvement in the reception of weak aural CW on 136.5, and in optimal circumstances, the IM-carriers could be reduced by up to 15 dB. Also the noise floor dropped by up to 5 dB, showing that some of my background noise on 136 kHz is actually TX-IM of DCF42 data modulation sidebands. However, I still had no success receiving VE1ZZ yet. The little circuit is not optimized, and the cancellation is narrowband (200 Hz) and quite sensitive to slight variations in received fieldstrength, relative phase and antenna tuning. The concept could probably also be applied to the Rugby problem on 73 kHz. As the frequencies involved are closer together and fit into an audio band, a soundcard software implementation might be quite feasible. And how about the Luxembourg crossmodulation around DBF39 (138.83)? One could think of subtracting the folded-down upper sideband from the offending lower sideband, thus converting AM into pure USB... 73 de Markus, DF6NM --------------080304020804090704060606 Content-Type: image/gif; name="IM_CIRC.GIF" Content-Transfer-Encoding: base64 Content-Disposition: inline; filename="IM_CIRC.GIF" R0lGODdhQAHIAIAAAAAAAP///ywAAAAAQAHIAAAC/oyPqcvtD6OctNqLs968+w+G4kiW5omm 6sq27gvH8kzX9o3n+s73/g8MCofEovGITCqXzKbzCY1Kp9Sq9YrNarfcrvcLDovHYIDZrDij A+q1wa1OAA7w82Jtf7tb+Dn5z+a3VxfI0KeH4Fe4uIcYqJjncghIRrgop5g4CUfXeNmphxb3 MkkpZun52SnISrealukYN4pZRzgYSVuqG2kqhRrrmMjY+mbcmHo4txysDPpIjLhZPO1rBXzX dgw5CvnZ+yzKpkr+SF0cfi6Lbv3LLawpBy9r/B28Ps4Mu1+t2qZurlS7KNj2aaJFLyA7TNJE NYvVTyC5fvEGuoN36160/nEcK6ZKB82TMoDVIpLUaFGJtloSn0Gr53FlzHrJcnVDx6ugOZcp e/r8CTSo0KFEixo9ihQESkMI/4XyNqxj1IPcaiJjejUpl6V3pjaLOmhe1mNTYXZM5pWrVoIV IJp9S5YmRLeulmYSJNWV3mVrt+iD+RVsmq5Q+cbVe7gr4rxm7/bVggfwYLDdXnLEm6+uPM3g pDqe3PhxFqiZQdM0ePl0asyL/+b9DNdzWdFUSBvevNc0a8N4WYeGHXpx69m0fyG+Pdt3cG+Y eeMu/Rb4PenFrw1XLPm578jZhwOXLTx47OpOEDJ++v2p8N3hc9oGB9u82i95OpuaT55I/Y+A /vDnF7Kff13w998RARaIYA0HJljcPw4+CGGEEt4kIINAVfgcBwFOyGGHHhJo4Q8YEqfBgh6M iF2IRaA4HgYmdsBihioCWKJSfcRoWo0zrqjjiTcqdeKOPGaAYy2hAAmjkPr1GESRLSqpQ4xO rjDllFCiIOWSSV4JRJZDVMlll0xqKOMGYIbpg5cw3mXlkxS0iaYIapp5Vp0gPnBmnDvMSWZa bjqQp5458EmnV+FNECgErLwo6JhtIXncoRIkCihdpDVKpKNjvnPepEFGgFxqZN2JaY6PfkBX PoS66Gl8dSlXKp6ajuAkpYq5ehicO65K65YWdAhLfYZeGqusmfYw/iGiHDZwKXOwFmvIrDYk O+my0UYXGaladbYhSp/xOq2Eg1rY7HXXqsYqsuLioOtP6Z1WWW7H8kAttCYg08s7va0EroLr gmqtvbpFqhpyzyKa5r+KBixwWYUJBp2o6dKrMJ4M21suuqIa/CegCUc4Lx9lvlnVKyxVBBK7 nFj2bWIHe6ouyBPz8a6yrTjkz0MMlWNdyFFW/CYMuRAJn2sozzSSfVD0W6lGJTPrMNAIkyIs q7ioRxVDN+bbLrvSegwXd52Ch56DPlM5i5lzFRKWPTppqxLJUpuqmZ07ka2QUzOzYHaJa+OM WkD48MyWzTJbLNJZzqja1Nyg+vhh5Erj/oNz5UYDPhJkch8ONnjsNYd3vb9+anioKaJm0zlr s32zeU04DimbdjAHb9Scn9qn4X923Q7sqB76ee2t+d55oTZLSiJ5vl/M7MqAcdeb7RCevffC yV/f4O3Bai+D6LgbDzPy4tO2vPczmD917iXwbg3xI4fLfbWSP4glufFDHfP01e8fwvz+yzSg +51rT+4b4NeKZ6zH+SqA+ksfAQWYQPAVD27+sdVouOetjzVwdAvs3OToZkDqXXCDyGOfhgp4 OhFOxnX4U6D6thI/pw1QdibMGwC/d8BXffB9IOSgF4CmtOlwqmOQI2HQOti8GyJwifzDwr+G ZirnEMtoqEJh/g/b8r8POTCHtQEZWmTEMayJrYoQZOK99NY/0jHQiAjcDmHGdwH0hU8FzNhh E3HolzJmSCbTqVP/rMjDXt0tjUiEjB6ThytVEXFz9LujIC0DKQnmkY1mlE622iXHbADSh4Tj ogtheEg4RlBOKGTeCTCpxgva0I6BVNQZQ2lKI1jQHVVp5BYHtUkO8gtuKZjlE0QSykVSLZhx tJQo6ZhKgjiNmDX0GzEfZcxRzQU+yRmeDAs5QlvO8WewNF8Y7eTGSE1RGIV55jFpqc1PiqmY FQun3cTzzuzcppyUVOck0+nKL7nIe/waljWHlkg/XsacwlwaM7X0wha6aowt+412/rqFRk6a jGW85CY+RymiZJ5rmtvQDnqGkSrK1DOf/sxVEgDZzN9hU4SOCWlg/JjLJ7mFdhU930H1uVL+ 9dNhurHFRbfJE7H9JaVrGmkK06RRA8WQpKebp0C7dFMa5VQ/9+OKXeRBu4J2L6pNSqosq4rR rEJnqF/i6joTioS5fVCIT3sJFUVk1oxOtaxGHOMVgdqkuCJ1rgDi3Fjuas+8GhWwXuOrYBtZ UaLiMouMbaxjHwvZyEp2bGZs2FoyiVHL9iWmlNXsUTirWM8acrAtFO1m9Ri59pkWYKRN7X1q ijH3ubY/LFytQ0ibFLXYYqK8XU9bJ4KvncG2rKv4qWis/po5wDWkp607UjyuNpMp4Au3SLFL 0Vj3XJdet7bQxVwdhzuu7fUNccCihBI7GpO/uTRnigwcdhVyNGW2VotffWywLIa0aYYUI2xi StYG10kmyJa+Q5LfRXU7ROXGV2diWSZVTnIF0P6SkRElGX+xq2AhziMaGR5qc7uXorUmh6Cd RShrjYtfwbl1UWXaGqd+lN+GsJKUqCvhiKlLWKkaeLxQCpXpMhMvbOG4lTjdcYWF9OM+ioNx RRsy9gp8Yh4jOTaBAd13JFweCp9XRUpMlZVvjOLMplXLtd1ViCH2zbJtObBjLt2RlWSb4jon YvqV8hFfR+YZr1a8b8Zrm428/uY9Ny3MlZVlnsFrWizj2c2BFjRWCF3aJbAotHpStIBV6Ogo 95nNBsJ0pslr51ue1NOfTqJkKb0+Upe6KJNedYNU7WqhtDrWj5k1rS8L61ufurFRyjWtOduf WwO6zBcStqYb7RNUownYJwXRfJQdpl0j2qbW5bSxT5lWD8/OjtCeUTMreJMNn3EjCo60sfWc 68wF+I/kfutRf01sw7Z72ljUhrrFrOteKoucoc3Icpl67RLLG4D0xiIoKGLuc+u7WpeIt1wD jmxJNu/fBRdawHv7SOuJsdsSF/a3J+zIi8sJ5HEUOd/+1+t9SnvlLG+5yyMbbJPbCNKjkfnM Q00fZJuTEec/1HkRNz0gnxeV50EXutpo7kSjH53oW1G6M5nuF6cTDekRlrrKoa45q//KybXR +tap3jOvMxrd13i52c+O9rTbV+xsb7vb3w73uMt97nSvu93vjve8633vfO+73xtVAAAAOw== --------------080304020804090704060606-- From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 13511 invoked from network); 14 Jan 2001 23:09:42 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by 10.226.25.101 with SMTP; 14 Jan 2001 23:09:42 -0000 Received: (qmail 1121 invoked from network); 14 Jan 2001 23:13:07 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 14 Jan 2001 23:13:07 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14HwDp-0002jB-00 for rsgb_lf_group-outgoing@blacksheep.org; Sun, 14 Jan 2001 23:06:01 +0000 Received: from cmailg6.svr.pol.co.uk ([195.92.195.176]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14HwDo-0002j6-00 for rsgb_lf_group@blacksheep.org; Sun, 14 Jan 2001 23:06:00 +0000 Received: from modem-79.earendur.dialup.pol.co.uk ([62.136.165.79] helo=lvm) by cmailg6.svr.pol.co.uk with smtp (Exim 3.13 #0) id 14HwDc-0007X0-00 for rsgb_lf_group@blacksheep.org; Sun, 14 Jan 2001 23:05:49 +0000 Message-ID: <000201c07e7f$09723580$4fa5883e@lvm> From: "LAWRENCE MAYHEAD" To: "rsgb lf group" Subject: LF: Re.

The correct place for antenna loading coils are directly beneath the vertical drop wire of the vertical if it is base loaded, or hanging vertically if centre loaded. During the early 1960 period there was a debate going on about where to locate the loading coil for 160m on short vertical fixed antennas and mobile installations. The consensus of opinions after testing was NOT to screen the base loading coils because they contributed to the radiation of the signal. This was also the case on 160m mobiles. Those with the loading coils in the boot/trunk of the car and screened radiated a weaker signal than those with the base loaded coil exposed at the base of the normally 8 feet vertical. Field strength tests at rallies confirmed this given that those tested were running the same rf power. Any vertical that I have ever used for MF or LF that needed a base loaded coil had it positioned vertically at the bottom of the vertical wire drop and this works very efficiently, any derivation from this degrades the radiation efficiency of the system. Locking loading coils up in farady cages is bad procedure on 73/136 khz with the power levels we are using. It was also found that long narrow loading coils positioned vertically at the base of the vertical and not screened, radiated more efficiently than SQUARE coils. I expect the long narrow loading coil acted like a continuation of the vertical getting more like a helical wound vertical. Wind you coils with teflon insulated 2.5mm or larger wire, get them outside at the base of the vertical in the rain, snow, frost, wind etc to keep them cool and you will not have any problems.

A quick guess of Larry's QRA at FN25EL and Ko in JO22KF would put that at a distance of apx 5630 km. If signals were 10dB down from those on Friday night, just imagine how far Larry's QRS signal could go on a 'good day'.

On receive, the noise level was about 10 - 15dB higher than the previous night due to the QRN. As a result, virtually nothing was seen, except for very faint traces near 136.5kHz at around 0230 and 0430. Unfortunately, VA3LK's posting did not reach me in time for last night, so I was not checking for his signal. So not an entirely successful weekend, although good in that some signals were received in both directions. But since several stations on either side of the pond have now made it across, it can only be a matter of patience, and being in the right place at the right time, before a 2-way contact is acheived. Thanks to those who supplied signal reports, and to everybody for their efforts over this weekend. We should try it again soon. In the mean time, I'm off to get some sleep, and looking forwards to a relaxing week at work!

A big shame for G0MRF who chose the wrong day. I am sure he could have made the two-way on Saturday morning. However, although the two-way was not achieved, the weekend was not a failure. The one-way record has been broken in both directions, another Canadian has been heard across the pond, VE1ZZ has been able to see for himself the benefits of QRSS, and I am sure that many of us have used these tests to make improvements to our stations. And of course the interest generated by the OK1FIG expedition (judging by the very many crossband QSOs he was having to 7MHz) will have encouraged more to come on LF. Thanks to John, Jack and Larry, and the guys from AMRAD, for concentrating the activity at their end. Is there anyone listening tonight, or can I go to bed early?

I wasn't sure it was Larry's, i processed another image with Psp6 and AcdSee3.1 but all i did made 'em look even worse, still 84 countries to go for Lf DXCC hihi.. The other night i did not look hard enough for the other side, i watched all the U.K and in a 200Hz window of Spectran, these guys showed up as thick as broomsticks. A new clip for was MM0ALM, and a better one of OK1FIG.. OK1FIG, when he transmitted i could see the other signals go thinner! He was sucking the other signals down to 50% here.. Sure you can post Larry's trace on your website, i'll have mine up mine in an hour or so, this Qrss is even more fun than sstv! Fact is i have not have time to check the hf bands since last year february All time goes to lf now.. The 50Hz filter is just from the Timewave Dsp59+, could go to 25Hz but then all goes white and sometimes even too loud. One other thing that helped me i stuffing the Datong converter deep down some drawer i used it while they transmitted from LG5 and i did not see him because i trusted my dial frequency, it was off 450Hz and still is 81Hz off, it can't get any better.. Now i use the YXM preamp directly to the NRD, and i can read real frequency and get what i am looking for. I am sure i have missed much more Narrow Hell and Qrss the last year wich was also my 1st year on lf.. (It all started with receiving DL0SWA 147.3Khz 11-2-2000) One other thing i want to ask to you as an lf veteran, i received HB2ASB some time ago and right now i see HB9ASB, is he the same guy at different qth's?? If so, he better try from HB0 some time hihi..

The elements I have seen are the 'same colour as the noise' , and have been seen in odd quieter periods. No signs from Larry either. I will leave a monitor running logging screens. I have reverted to Easygram which seems to me to perform a little better in these circumstances. Maybe I am more used to the settings.

Yesterday evening contacted Jiri OK1ARN with vy string signal but no trace on spectrogram of VE1ZZ transmission. At around 23:00 wind became to strong for my TX antenna to stay up and electrostatic noise raised too much for QRSS reception. At now is the same, strong wind and S9 crack noise on my small T receiving antenna so impossible to TX and RX for VE1ZZ. I'm very sorry that I cannot play any role in this trial, so best luck to all involved.

The telephone should be OUT. Either aim for two way on 136 khz or use xband but email and telephones confuse all concerned. The only presons currently active that stand a real chance of a transatlantic qso are MM0ALM and OK1FIG with their large antennas, also VE1ZZ has an elaborate antenna system, with the present propagation the rest are just QRM to one another. The best approach would be to have one night tests using normal cw and a different night for slow slow cw. The only other person with a chance is G0MRF from his /P qth with his big antenna from a tower block. Another point that some one made is that Jack spent too much time chasing OK1FIG to the detriment of all others waiting. I have seen this happen on 160 metres and it can be very frustrating especially if there is a short time slot due to propagation changes. Would suggest that if you do not make it after about 3 attempts pack it in and give others a chance. On normal cw I suppose it would work better than the very QRS method where even if you got it first time it could take an HOUR for one qso. This is very anti social except you set aside one night for this mode only. In spite of all the confusion I hope someone makes it this weekend. I do not mind waiting for a while to make a solid qso on normal cw. 73 de G3KEV From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 6364 invoked from network); 13 Jan 2001 18:32:00 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by extortion.plus.net with SMTP; 13 Jan 2001 18:32:00 -0000 Received: (qmail 16919 invoked from network); 13 Jan 2001 18:34:40 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 13 Jan 2001 18:34:40 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14HVQw-0004Wb-00 for rsgb_lf_group-outgoing@blacksheep.org; Sat, 13 Jan 2001 18:29:46 +0000 Received: from [212.159.14.225] (helo=murphys-outbound.servers.plus.net) by post.thorcom.com with smtp (Exim 3.16 #1) id 14HVQv-0004WW-00 for rsgb_lf_group@blacksheep.org; Sat, 13 Jan 2001 18:29:45 +0000 Received: (qmail 12601 invoked from network); 13 Jan 2001 18:29:03 -0000 Received: from unknown (HELO picks) (212.159.57.10) by murphys with SMTP; 13 Jan 2001 18:29:03 -0000 Message-ID: <007401c07d8f$d1893780$d33b9fd4@f9.net.uk> From: "Dave" To: rsgb_lf_group@blacksheep.org References: <006501c07d80$d2a21f60$d33b9fd4@f9.net.uk> <3A6099BF.CB47A1A1@netins.net> Subject: Re: LF: ATU rebuild.

Back on the air now and I have lined the ATU hut with metal, both aluminium sheet and aluminium cooking foil! All this is bonded to earth. Everything is much more docile with less corona from the top of the coil so I thought maybe current was down. I measured it and current (measured on the antenna feeder outside the box) is 10 per-cent better for the same input power. I therefore recommend putting your loading coils in large earthed metal boxes! It avoids losing power in nearby lossy structures and may contain a melt-down better.....

There is also another 'O' report for OK1FIG at 0615z. I suspect Petr was not getting the reception levels he needs for some reason. I was surprised he did not hear several stations including Tom G0OLB calling him on manual CW on Friday afternoon. The furthest station east I heard them work whilst I was listening was ON6ND. I think other reports confirm my thoughts that propagation last night was not was not up at the levels we have seen it in last couple of weeks. Which suggests that under the right conditions a lot more could be possible. Well done all.

With my very poor antenna, I received several times 'MM0ALM', just about 40 Hz above the strong OK1FIG signal, but I thought it was MM0ALM calling.

My best copy of Jack was at 0000 when he was giving Petr a report, a good "O". Nothing at-all 0030! I left Argo running and taking grabs every half hour, the best copy late in the night was at 0430 and at 0500 with another, not quite so good copy at 0700. I don't think there's any way Jack and John would have copied me based on the strength I was getting from them and the ERP Jack is running. Still, we live in hope!

He has seen nil from VE1ZZ this night but is happy he has been seen at the other side of the pond. According to my calculations, this is at least a new LF world record, bridging 5697 km (if my estimation of VE1ZZ's QTH as FN84CM is correct). Conditions were obviously not good enough over to the European continent, I myself saw no signs from Canada until 03.30 UTC when I could see very weak traces ('T') of a QRSS signal on 136.500 kHz. Petr and Jiri will remain QRV until about noon today and then go home. According to what I have seen on the cluster they were heard quite well all over Europe, reports came in from Estland and even Moscow.

The noise levels are low and we got 2 good setups with notebooks running ARGO and SPECTRAN. Loran artifacts can be heard but they are under control. The new active antenna is working fine business. Copied LOWFer DCH from Berlin MD and VE1ZZ was coming in all evening usually copyable aurally as well as visually. We watched for OK1 station but did not see anything. We also monitored 135.900 -135.980 and did not see anything there either. We plan to try some other things in tomorrow's daylight. We set up tonight in the dark and are not sure what we will see in the daylight. Weather is not too cold and just a few spits of rain. We are anxious to try to see Dave, G3LDO's signal tomorrow night. Everything will be tuned as best we can for that time period.

I think we have now passed the best part of the night with perhaps another good part around 5 or 6 am. So going to bed - but have massed a lot of grams, which I will post on my web page tomorrow.

I guess from this afternoon listening to Petr he is not hearing as well as he is transmitting from that site. The problem here between 2000 and 2100 was a fair bit of noise and the signals from Jack were right on the edge of the noise. I was getting the best copy in 2.1kHz filter with the gain right down, but I could not decode the 'signals'. I think in that configuration the big signals on 135.9ish were chopping the RX up a bit. I expect he may get better in the next hours or so. Yes John, I was worried about possible CMEs there was an M-class flare just 2 days ago, but there was no indications from NOAA. I think I must be looking at the wrong site!. It rather depends on circumstances what its effect will be, but it could be that the early evening may be the best after that strikes.

Now both have a sort of horizontal spider's web filling the whole area between the masts. Rugby still has the original 12 guyed masts, which are 820 feet according to the paper. Criggion originally had 3 x 600 foot self supporting masts; these were all that was available during the war, and were not considered enough, so the station was sited adjacent to a cliff, and one side of the top load is anchored to the top of the cliff. Since then, 3 x 700 foot guyed masts have also been added to the antenna. Rugby was also used experimentally for early trans-atlantic telephone services, using ssb on about 60kHz. For this purpose, the main antenna was divided into two sections, the smaller part carrying the telephone signal. Both VLF antennas also have various smaller L and T antennas for LF slung lower down the masts. Rugby has a whole forest of what I presume are HF antennas, across the road from the VLF/LF site. Originally, Criggion had several HF Rhombics too, but these are now gone. As far as phase control goes, the 1926 paper describing Rugby mentions that the frequency was derrived from a valve maintained tuning fork. This apparently had a tempco of 100ppm/degC, and was regarded as a major advance in transmitter frequency stability, and neccessary because of the increasing use of the spectrum. By the time Criggion was built 18 years later, crystal oscillators with 1 in 10e7 stability over a period of months were in use. If you visit either site, it is worth taking a pair of binoculars, since it is hard to see much detail from ground level (but be prepared for funny looks from the site staff!). I heard that the telegraph poles and cables over the road at Criggion are there to support the top load when it is lowered for maintenance.

The phase stabilisation Alan mentions allows, amongst other things, the remote monitoring of transmitter health from remote sites . Who said that ?! :-|| According to Tom Clancy, in "The Hunt for Red October" there is a transmission of coded groups to very deep operating "Boomers" at a data rate that appears to be in the region of a bit per second (one minute per message). The groups would encode messages such as "Come to the surface immediately for a satellite transmission", or "Fire !". If it is not all a fiction invented by an author with a large collection of friends working at interesting places. Speculatively of course, this would be at a frequency in the 60 - 170Hz region - which makes even amateur 9kHz experiments seem tame. It is stated that in the US there are lines looking like old fashioned telegraph wires many hundreds (1000s ?) of km long carrying signals that make fences spark. At these frequencies a ground loop antenna is the only realistic sort of antenna that could be made to operate with reasonable efficiency and long low slung wires which wouldn't have to even be grounded at the far end if long enough would form just such an antenna - Some people have suggested - and this is no sxcrxt - that the UK tried some propagation tests at ULF (Ultra Low Frequency, 30 - 300Hz or shold this be SLF) in the 1960s, but decided we didn't need the deep operations around the world this would allow. I was told once (by someone long retired from the business) that there were ideas to use the third rail of the railway network to form the antenna for a ULF transmission, others proposed the National Grid but the idea of a multiplexer to separate 50Hz from the transmitting freq (at say 100 Hz) would be 'interesting' Anon G^JN* > If anyone can arrange a visit to Rugby Radio Station before > it all goes the > same way I am sure there would be plenty of takers. > > Cheers de Alan G3NYK > -- The Information contained in this E-Mail and any subsequent correspondence is private and is intended solely for the intended recipient(s).

The TX has also been updated at least once since those days. I suppose that must have been the time it moved to data transmission rather than morse. I think you may find that the poles and wires across the road are what, I believe, is known as a T/R cell......but just perhaps I shouldn't know about things like that! I didn't know about the Caernarfon site, Mike but I agree with you, technical artifacts of this vintage are easily lost. They are not yet old enough to be historical to most people. I suggest you drop a message to the Welsh Heritage Secretary....I would think in the present climate you might get a sympathetic hearing. 1938 closure might not be as silly as it sounds, it may have been regarded as too vulnerable to a naval (submarine) artilliary attack. The RAF Experimental Wing was moved from my next door airfield to Boscombe Down, in about the same year. If anyone can arrange a visit to Rugby Radio Station before it all goes the same way I am sure there would be plenty of takers.

(Brilliant thinking). The concrete foundations for the masts are still there, the field is littered with pieces of shattered insulators (like our old 'egg' insulators but about brown and 12 inches long when complete. Best of all is the building, still standing virtually complete and now used as a riding school. If you inspect it (with permission) you can still see the old feed-throughs, and match the patterns of the brickwork with the old photographs. It ought to be made a listed building. There is no other of that period still standing, and if they can list a WW II radar mast then this is even more historical. 1915 - 100 wpm to New York 24/7 and not a valve in sight! First pictures to Australia too. Sorry for lecture - my favourite subject!

The loading coils for both stations were wound as spirals on five hexagonal wooden spiders, roughly 4m diameter. The spiders could be moved to vary the inductance, which was about 2.5mH for Rugby, and 5.4mH for Criggion. The wood is described as "American whitewood", which the Post Office engineers apparently found was a highly satisfactory material; no other insulation for the windings was used. The antenna voltage and current was 220kV, 400A at Criggion, and 160kV, 600A at Rugby. The windings were (HF) litz wire made up from 6561 strands of 36swg. The Q was in the range 2000 to 4000. The Rugby transmitter building was designed to minimise the amount of metal, etc. close to the loading coils, while at Criggion, the loading coil was inside a reinforced concrete building. This caused high losses until a Faraday shield was installed by lining the walls with a mesh of copper wires. The Rugby transmitter building burned down in 1943, so we are not the only ones with these problems! Both these stations are still there (obviously modernised a bit), and worth a look if you are passing by. Rugby is by the side of the A5, and Criggion is on the Welsh borders a few miles east of Welshpool. The road to Criggion village actually passes under the VLF antenna, so you get a good view there. It is interesting to read the discussion at the end of the Rugby paper - some audience members state that the VLF station had effectively been rendered obsolete by the HF beam systems then coming into being - yet, 75 years later, GBR is still there on 16kHz, and it is the HF systems that have disappeared!

If so, the answer is "Yes", I was concerned that the bulletin put out by Andre, N4ICK on this group was being ignored under all of the e-mails about Eu-VE. Since you may have the best signal from Europe, I suggest you contact Andre direct at 73 and very good luck.

Firstly, AMRAD will be doing receive tests from the North Carolina coast, and this extends to Sunday night / Monday morning (Eu time). They will want some Eu signals to listen/look for, even after John and Jack have finished. Secondly, it would be really useful for other Eu stations to make comparisons of the signals they hear/see. I have found it very helpful to see how my signal compares with others on a spectrogram. Thirdly, this is a good opportunity for various Eu stations to record how they receive VE1ZZ at what times, so we can see how propagation varies. Lastly, there is still time for someone to record (preferably as a computer audio file) the first normal speed CW from VE. This should keep many stations busy whilst the really big guys try the two-way. Have fun.

WPM (Words Per Minute) is based on the 'PARIS' system, where PARIS is taken as a standard word that has a length of exactly 50 dots (including word spacing).

So : dot length (seconds) = 1.2/WPM 73, Rik ON7YD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 1964 invoked from network); 11 Jan 2001 10:04:48 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by 10.226.25.101 with SMTP; 11 Jan 2001 10:04:48 -0000 Received: (qmail 7464 invoked from network); 11 Jan 2001 10:08:10 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 11 Jan 2001 10:08:10 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14GeXr-0006cX-00 for rsgb_lf_group-outgoing@blacksheep.org; Thu, 11 Jan 2001 10:01:23 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from [213.2.16.106] (helo=rsgb.org.uk) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14GeXp-0006cS-00 for rsgb_lf_group@blacksheep.org; Thu, 11 Jan 2001 10:01:22 +0000 Received: from miked by rsgb.org.uk with SMTP (MDaemon.v2.8.7.5.R) for ; Thu, 11 Jan 2001 09:49:53 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 From: "Mike Dennison" To: rsgb_lf_group@blacksheep.org Date: Thu, 11 Jan 2001 09:49:51 -0000 MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII; format=flowed Content-Transfer-Encoding: 8bit Subject: Re: LF: Weekend tests Message-ID: <3A5D81BF.26864.29853A@localhost> In-reply-to: <3A5D0D90.7E2D4ECF@ns.sympatico.ca> X-Mailer: Pegasus Mail for Win32 (v3.12c) X-MDaemon-Deliver-To: rsgb_lf_group@blacksheep.org X-Return-Path: miked@mail.rsgbhq Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: > Perhaps we should listen (look) for 10 second dot qrss after say 0300Z > providing a QSO across the pond has occurred > I hope this helps 73 de John VE1ZJ This would certainly be useful but we will have to modify our procedures for this speed as just a callsign takes more than 20 minutes to send! I suggest (for 10s dots only) sending the absolute minimum of info, only the suffix and no "K". For example: G3XDV: "XDV" VE1ZZ: "XDV M" G3XDV "R O" VE1ZZ (not receiving well): "?" G3XDV "R O" VE1ZZ: "R SK" I will try to get on with 10s dots but I have a peculiar problem as my QRSS generator is a MOSFET keyer with tens of megohms in series with the timing control.

Assuming I can see your signal, I will wait for you to call me before trying to send signal reports, etc., and will wait until the beginning of the next 15 or 45 minute period to start transmitting. This should minimise problems with transmissions from different stations overlapping. I will stick to the frequency plan on G3XDV's web pages, ie. 135.916kHz for me Please note - I don't have any E-mail facilities at home, so will not see any e-mails until at least the day after they are sent, during the weekend. Alternatively, I can be reached on 01707 643461. Best of luck to all those involved, and hope the weather is not to wild in UK or Nova Scotia this weekend.

They may be gases, liquids or solids at "room temperature" depending on the molecular weight. In the UK, "paraffin" as used for a fuel, is a crude mixture of liquid paraffins defined as above, together with some benzene derivatives, which account largely for its odour. Paraffin wax belongs to the paraffin series, being a mixture of various higher molecular weight compounds, depending on the melting point of the grade.

This will give room for those of us with less than a watt ERP to make it. It is best not to run the two standards in the same set of tests as this will reduce the number of people monitoring any one standard.

Most of the time I only need two progs for the 56002 itself. One, called DECIM01.CLD, mixes the audio frequency with a commandable local oscillator anywhere in the range 0 to 3.2kHz to generate I/Q channels at zero frequency then filters and decimates by a commandable factor to 4000 / 2000 / 1000 / 500 / 250 or 125 Hz sampling rate with a bandwidth of 0.8 times Fs, then outputs the resulting samples at this rate to the serial port. Commands to set centre freq and decimation are sent to the 56002EVM via the serial port. The PC then uses these 16 bit Zero Frequency I/Q samples for FFTs, phase plots etc. The second prog, DECIM03.CLD, adds another /64 stage of decimation within the EVM to give output data sampled at 62.5 / 31.25 / 15.626 / 7.8 / 3.9 and 1.95 Hz. (I would like to combine both into one EVM routine but can't be bothered !) The ultra narrow band monitoring software uses this lowest data rate from the EVM, then performs yet another decimation and filterieng operation, now within the PC, again at a commandable factor up to 64 times to give a sampling rate that can go down to 0.03Hz. A 256 point FFT on this gives 0.0002Hz resolution but down at this level, the raw I/Q data is better saved to disk for later analysis. The frequency accuracy of the whole proces is that dictated by the receiver (locked to a master reference) and the 8kHz sampling within the EVM which could be locked to the reference but isn't. What a pity that none of the VA/VE stations transmitting can maintain the sort of accuracy needed by this. The ability to make vector measurements of absolute phase over hours in mHz bandwidth would reveal infinitely more about LF long distance propagation than just power measurement alone. For instance, it would reveal directly any Doppler shifted components, be able to separate out ground and skywave components and show whether fading or enhancements are caused by multipath or changing ionospheric conditions.

Regarding the number of times you send the report : depends on how well the other station can copy you.

Its not "two Nations divided by a single language" this time.....It is the problem with scientific definition and popular (corrupted) usage ....a "transistor" is an AM portable radio..actually !! Paraffin is the general popular term given to a grade of heating oil, and Jet engine fuel. Where scientifically if I remember my organic chemistry correctly ..."the paraffins are a family of straight-chain hydrocarbon molecules" ....cor that was dug up from a long time ago......hope I got it right. The Wax is a high molecural weight member of the family usually popularly called "Candlewax" in the UK. Its all good for a laugh. By the way the last time I was at Rugby GBR (16kHz) in the tuning loft, the tuning-coil/variometer was made of 'litz' the diameter of an man's wrist (I believe I was told it was 800 and some strands) and it was hung on an 'well seasoned oak frame' I believe. It was definitely varnished wood, and we were cautioned that there was not a nail or screw in it. The construction was all joints and dowels. This was in the early 60s when it was still sending morse and the TX had not been phase-stabilised. Every time the key went down the coils 'tensed' like great muscles, and relaxed as the power went off again. I asked but they did not seem to get trouble with work hardening or fatigue. I believe the room was shielded by mesh but I cant remember now. Dave has a way to go yet as they were only running QRP at 500kW. Another 500kW on hot standby and a third bank was in maintenance.

It is easy to run, is very sensitive and continues to run when you are working on another program in a foreground window. [snip] Mike, thanks for your nice words. What you call 'frequency error', and which I would call 'frequency uncertainty', is caused by the relative values of the sampling rate and the FFT size. In the full band view, the sampling rate is 11025 S/s, and the FFT size is 4096 samples. This gives a frequency resolution of 11025/4096 = 2.69 Hz (roughly). This is the uncertainty with which the frequency can be determined when in that mode. If you look at the peak display, you will see that it says : Peak at nnn.nn Hz +/- 2.69 Hz The +/- value is the uncertainty. For the other modes the values are different, but you get the idea. When you scroll up and down the scale, it may happen that the peak falls in one FFT bin or in the adjacent one. It's not a continous movement, but rather a step one. So it maybe that, for example, if you measure the mains hum picked up by a piece of wire, at the beginning of the scale you find that the peak is, let's say, at 49.9 Hz, and scrolling you find it at 50.2 Hz. This is not an error, it's just the consequence of what said above. To measure with great precision, it would be necessary an FFT length of several MegaSamples, with the inevitable long time of acquisition. Then you could go in the milliHz region, as by example Andy does with his EVM56002 (I have one, where can I download your software from, Andy ?), but be prepared to long waits between screen refreshes. To answer to John's question, to choose the 'magnitude squared' estimator, go to the action bar, select Mode, then Spectral Estimator, then Magnitude Squared. This is present only in build 113. 73 Alberto I2PHD ____________________________________________________________________ Get free email and a permanent address at http://www.netaddress.com/?N=1 From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 29369 invoked from network); 9 Jan 2001 22:48:43 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by extortion.plus.net with SMTP; 9 Jan 2001 22:48:43 -0000 Received: (qmail 28112 invoked from network); 9 Jan 2001 22:51:23 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 9 Jan 2001 22:51:23 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14G7Vm-0005vb-00 for rsgb_lf_group-outgoing@blacksheep.org; Tue, 09 Jan 2001 22:45:02 +0000 Received: from mta01-svc.ntlworld.com ([62.253.162.41]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14G7Vl-0005vW-00 for rsgb_lf_group@blacksheep.org; Tue, 09 Jan 2001 22:45:01 +0000 Received: from oemcomputer ([213.104.107.175]) by mta01-svc.ntlworld.com (InterMail vM.4.01.02.27 201-229-119-110) with SMTP id <20010109224451.FDII6427.mta01-svc.ntlworld.com@oemcomputer> for ; Tue, 9 Jan 2001 22:44:51 +0000 Message-ID: <005801c07a8d$b2f2ae00$0f6968d5@oemcomputer> From: "mike.dennison" To: rsgb_lf_group@blacksheep.org References: <3A5B37BB.11936.1878C3D@localhost> <3A5BC206.5AE2A045@ns.sympatico.ca> Subject: Re: LF: ARGO Build 113.

I had suggested that we could get away with sending it just twice for the transatlantic tests. Of course, if someone sends an O to you first, it should not be necessary to repeat, but the level of QSB may make repeats essential. In any case I am not trying to dictate, just to suggest an efficient approach.

The base of my loading coil is only about 15 cm above ground. So it seems that I should be able to make some improvements when I rebuild the loading coil later this year. By the way, as at G3KEV, I have also designed all my equipment to match to 50 ohms, and tune for minimum SWR. I find that continuous monitoring of SWR provides a very sensitive indication of what's happening at the hot end.

I have arranged the functions of the SL 621 around a LM324, including a few diodes; the only thing which I have made differently is to take the AVC signal from the I.F., not the A.F. as in the application of the SL621. The s-meter indication will remain the same, no matter whether you speak as usually or whistle into the microphone. QRN will always be a problem, I think; in my circuit this should not matter as long as the peaks of the wanted signal are higher than the qrn peaks, otherwise the QRN peaks would take the lead, of course.

I'm suprised that people have had success with coils exposed to the rain, I found with mine that this drastically reduced the Q once water got in between the turns. Hello Jim. My loading coils are outside and I do not suffer from any detrimental affects in hot sun, rain, frost or snow or rain of any sort. The swr meter shows virtually no change in changing wx conditions. I do have a fairly high mast at 120 feet supporting 3 x inv L antennas with 250 feet horizontal top sections. The coils are wound with 2.5 mm multi strand plastic insulated wire. My coils are 6 feet above ground and vertically orintated and I have never noticed any water or snow etc in between turns. The coils also run cool, not even warm. I have a fairly elaborate insulated ground system. I can run around 1w erp. The coils at the base of the antenna vertical are matched to the 50 ohm coax feed and are about 90 feet away from the shack. Not much chance of my shack catching fire. Ever since I started on LF some 3 years ago I never had any problems with the installation, no fet, insulator, wire etc failures. I have built the installation to match 50 ohms and always tune for minimum swr, this always coincides with max rf output. I NEVER tune for max SMOKE!!!!!!!!!!! This could be a recipe for disaster. I do not have any PA protection.

The material tested is called "COROTHERM" and as mentioned earlier, is available from most DIY outlets Burn test - Does not support self combustion. When held in a gas jet just melts and gives off sooty smoke with a small luminous flame, turning to carbon. No noxious fumes are given off, unlike other plastic materials. When removed from flame self extinguishes immediately. I believe this is a requirement of many building materials now. EM fields - Placed a 100 x 200mm piece in a microwave cooker (with the statutary cup of water to protect the cooker !) The test piece didn't even get warm after several minutes of 'cooking'. Paxolin or SRBP sheet, in comparison, gets very hot with this same treatment. On memory alone, a 2.4m long by 0.6m piece of double walled 10mm thick sheet costs around £25 - 30 (UKP) from B&Q. Looks ideal for ATU huts, and even formers for large coils. One side is ultraviolet protected so when using outdoors it has to be mounted the right way round; the peel off protective film labels which side is which..

I have seen people send zero instead of O, wasting several minutes, as well as QTH, power level etc. The idea is to be as brief as possible whilst keeping the message clear. Rik, ON7YD has a useful web page showing a typical QSO, and I can recommend it to anyone new to QRSS. It is at http://www.qsl.net/on7yd/136narro.htm I suggest for this weekend a slightly shorter format than shown by Rik. A QSO could progress as follows: VE1ZZ: "VE1ZZ VE1ZZ VE1ZZ" etc for 15 minutes.

K" G3XDV: "ZZ R O O K" VE1ZZ: "XDV R R SK" There is no need to send '73' or 'TU', just 'SK'. Don't use 'QRZ' or 'AGN', and certainly not 'PSE RPT' - just '?' will do. Don't use full callsigns once the QSO has started, the suffix is enough. Only use the other station's callsign during the QSO. If you are unsure that the DX replied to you, it is permissible to use your own suffix as well but without the 'DE' (G3XDV: ZZ XDV O O K). Never use RST - the reporting system is: 'T' = Seen but not readable. 'M' = Readable but not 100%. 'O' = 100% of every character seen clearly. The golden rule is not to send anything that is not needed. A QRSS QSO can take 45 minutes. Using this procedure it will reduce to less than 30.

Yes, that would work quite well. In fact G4GUO did just that on 73kHz a few years ago using the 56002EVM with left and right channels for I/Q and a downconverter fed with quadrature square waves in a mixer made from 4066 analogue gates. There is no need for a DDS with quadrature outputs, switching mixers works best if driven from a clean square wave. The LF input has to be filtered to remove frequencies mixing with the third harmonic of the LO, which of course would have to be done with any mixer type - again the 100dB attenuation at 1MHz freqs, you can't get away from that so easily ! One problem is the 3kHz (or whatever) lowpass filters. These have to be analogue and very very precisely matched to preserve the 90 degree phase relationship. Switched capacitor designs, such as used on the Codec input, will work to an extent, but even these require some analogue filtering to remove frequencies interfering THEIR alias products. I'm not really a proponent of wide band digitisation then subsequently filtering, unless that is really what you want and need for simultaneous band monitoring purposes. Better to optimise gain / dynamic range, analogue filter to a few 100 Hz bandwidth then digitise at a lower rate. Andy G4JNT > perhaps I didn't make myself clear.

I think this makes sense. But, of course, if it did catch fire I would burn really well. Just a thought.... As a sail boat owner, I know how easily water can get under varnish and never leave -- while the wood discolors and rots. If one were to varnish wood that's going to be exposed to the outdoors, a marine varnish might make good sense as it has ultraviolet inhibitors to keep the sun from eating it up. I use a marine varnish called Sikkens (?) from Europe that really stands up to the weather.

I would like to suggest some procedures to maximise that opportunity and minimise mutual QRM. Please feel free to point out any flaws in my argument. As far as possible, continuous beaconing should be avoided, especially if another station is operating near to you. Transmission slots to be 15 minutes: VE1ZZ transmits from 00 and 30 minutes past the hour, Eu stations transmit from 15 and 45 minutes past the hour. Send just your own callsign and wait for Jack to identify you. If a QSO happens, all other stations to stop transmitting. There is a frequency plan at http:www.lf.thersgb.net/transatlantic.htm using the sub-band 135.9-136.0kHz. This includes the Loran frequencies for the Canadian end. It is intended for guidance only, but it will probably help the chances of success if we make an effort to avoid each other. It will also help John/Jack/Larry and the AMRAD team to know which frequency to find what station. Please e-mail me any updates. If it helps, I can post telephone numbers on that web page, too (they can be removed after the event). I will post a separate message reminding QRSS novices of procedures. Good luck!

For RF purposes we have the other expression "RF litz" or in german "HF-Litze". In this case all the fine wires are coated with varnish to allow rf currents also run in the inner portions of the litz wire, where it would not go without this insulation.

A Metal Hut! I have rebuilt the hut and will be lining it with aluminium sheet bonded to earth in the hope that this will reduce the losses and be more fireproof! Next job will be the loading coil (I have some Decca litz waiting) and, the saddest loss, my remote-tuned variometer. It really is a big step going up from around 1kW to nearly 2 and you just can't get away with any whiskers of wire at joints where corona can start..... I'm going to have to call on my experience of large broadcast transmitters from 30 years ago! I considered having no shelter but I don't think it's viable at this power level, also the mechanics of remote tuning and the current monitoring would suffer from the damp. Has anyone got a suggestion for a fire detedtion system that would still work in close proximity to all that RF? I imagine a domestic smoke alarm would go doo-lally!

The UK is not the only area interested in making a contacts with Jack. In Continental Europe the section from 135.950 to the bottom of the band is useless for weak signal reception. Also the normally designated QRSS slot is close by DCF39, as we know from 73kHz that extra spacing can make a lot of difference. Here, probably the most easterly station in the UK, I can receive an intermodulation product on 136.0kHz from Mainflingen that would make reception of Jack impossible. As it is on 136.5 he is sitting a much weaker IM product from that site, which makes reception difficult before it fades at midnight. (These are not due to my equipement failings, as confirmed by Markus DF6NM) As I understand it the suggested band usage was for normal everyday use and it works well. Jack is an exception to this and all we ask is a slot about +/- 20Hz either side of 136.5 from say 2300z to 0500z. That leaves a considerable chunk of the band for normal morse operation at a time when it is normally dead quiet. If an operator who is not party to the goings on, operates on 136.5 well we must accept that....it will happen in the best regulated circles. I am aware that many operators do not want to be involved in QRSS, but you might be interested to hear that in my opinion Jack's strength last night was approaching the levels where an audible contact is possible (remember Dave did hear him !). This knowledge has only been achieved by continuous monitoring of his signal by computer. My aerials are by no means the last word but I estimate Jacks signal was a few, well maybe 6-10dB, below where I could hear him between 0100z and 0230z. It might just be worth listening in that frequency, as results suggest he may be stronger earlier further west from me. This is the Centenary of the first radio morse character to cross the pond, lets mark it style!

It's when the cats catch on fire, you have to look out! I have stood my loading coil in a plastic planter and covered the whole with a large tight fitting plastic bag, with the antenna wire rising from one corner and securely taped to keep the damp out. This seems to work, but it is near a wooden fence, so I shall move it away before using it again, although I am not in the high power league.

I am also active on all the other HF bands with a KT34XA giving me good world wide coverage, not to mention all the vhf/uhf bands including satellite up to 1.2 ghz. Think also of the legal implications about trying to supress freedom of expression via internet.

I'm suprised that people have had success with coils exposed to the rain, I found with mine that this drastically reduced the Q once water got in between the turns. The 20kV or so across the winding is a bit of a worry in the wet, too. Do hardware shops in Germany really sell litz wire, Geri? Interesting to see details of G4JNT's portable measuring receiver project; on and off I have been working on something similar myself. A significant difficulty with measuring signal levels on LF is how to get a sensible reading with on/off keyed signals and significant levels of QRN. A strong carrier or QRSS signal is easily measured with any old AC voltmeter on the audio or IF output - but it is not always possible to arrange such a signal. However, with manual CW (and presumably modes like BPSK), the varying signal level makes it difficult to get a steady reading. I have tried using a "quasi peak" type voltmeter (ie. a peak detector with a few ms attack and much slower decay, similar to many RX s-meter responses). This works well with CW, but any sort of meter seems to have problems with QRN; since the peak QRN level is often much higher than even quite strong signals, you get a few dB variation even with long meter time constants. Perhaps the most satisfactory method is to use an oscilloscope to display the signal, since then you can see and identify the modulation envelope and QRN spikes, but this is less than convenient for portable use! Another measurement that is important to make is the noise level, but this is also highly dependent on the type of meter response.

What I was suggesting was not to digitize directly at 136 kHz. My idea is along the following line : Using a DDS with quadrature outputs (AD9854, if memory serves), feed the two signals to two mixers, each of them gets also the wanted RF (in phase). The DDS operates at the direct frequency you want to receive. The two analytic signals generated, I and Q, are in the 0 - 3 kHz range, while any off band signal will generated far removed frequencies. So at this point you need just a couple of low pass filters to keep only what you want. We still are in the analogue domain at this point, so no aliasing will take place. After the low pass filters, you digitize with a low sampling rate, let's say 8 kHz, the two I and Q components, then you enter into a dedicated DSP chip for the processing you need (demodulation, filtering, FFT, AGC, etc.). Using those chips I mentioned in a my previous post, this can be done with minimal hardware, without the stability and temperature dependance problems that would affect a purely analogue design (please don't shot me !). 73 Alberto I2PHD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 12131 invoked from network); 8 Jan 2001 16:23:11 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by extortion.plus.net with SMTP; 8 Jan 2001 16:23:11 -0000 Received: (qmail 22470 invoked from network); 8 Jan 2001 16:25:49 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 8 Jan 2001 16:25:49 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14Ff0O-0006TH-00 for rsgb_lf_group-outgoing@blacksheep.org; Mon, 08 Jan 2001 16:18:44 +0000 Received: from [194.73.73.138] (helo=ruthenium) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14Ff0N-0006TC-00 for rsgb_lf_group@blacksheep.org; Mon, 08 Jan 2001 16:18:43 +0000 Received: from [62.7.78.193] (helo=z0w6t5) by carbon.btinternet.com with smtp (Exim 3.03 #83) id 14FGb8-0006NC-00 for rsgb_lf_group@blacksheep.org; Sun, 07 Jan 2001 14:15:02 +0000 Message-ID: <003301c078b4$76a75ca0$c14e073e@z0w6t5> From: "Bill Staples" To: rsgb_lf_group@blacksheep.org References: <001701c077ef$90ae3940$cf239fd4@f9.net.uk> Subject: LF: Re: Fire!

I have wound my 3.4 mH loading coild using normal 1.5 square mm litz wire from the hardware store on a core made of a combination of plastics and some hard wood rods as a carrier. I have put this coil about 1/3 of my vertical antenna height up without any protection. Result: no problem with rain/snow or whatever (however: running only 350 Watts output ...) and quite some improvement in receiving and transmitting signal strength plus much less voltage on the remaining fine-tuning 0.9 mH variometer in my shack and less trouble with my two cats passing by the coil insde the shack (see picture at http://www.qru.de/station.htm, about half way down the page).

The dustbin stands on four 100mm high legs made from plasic drain pipe to get the bottom of the coil away from the ground an reduce losses. May not be big enough for some of the larger coils though. Although a bit pricey, the polycarbonate twin walled sheeting (designed for conservatory roofs) and available from most DIY outlets (B+Q are reasonably priced) would make a suitable low loss housing. Use L-shape plastic moulding and suitable (low loss) glue to join. It is available 600mm or wider, and 2.4 / 3 / 5m m lengths. This material is very strong..

Then, as we are only dealing with narrow data, I felt an A/D converter sampled at a low rate, supplying samples via the COM port to a PC would be a simpler beast to write software for than being forced into the soundcard route. I do not like windoze programming and am not prepared to go the soundcard route - there are plenty of others writing S/W for that and don't want to reinvent the wheel. This unit will probably sample the 300Hz bandwidth and output the data at 1000 S/s. ALso, only certain soundcards can be guaranteed to have the performance needed. Already have three suitable mechanical filters spare, as well as numerous ones of higher bandwidth - and I need to do something with them all ! Anyway, direct zero IF conversion will still need extensive input filtering for anti-alliassing and in this case will be even more stringent unless an artificially high sampling rate is employed. For example, assuming 80dB spurious levels, the input signal has to be at -80dB at half the sampling rate separation from the edge of the passband. If a high speed A/D is considered - lets sample at 100kHz for now - then we need -80dB at 50kHz away from the centre of the band. (In fact, within this allias bandwidth are some very strong signals, so the 80dB requirement may have to become 100dB anyway) so we end up with filtering more stringent than the double conversion approach. And at least to get rid of 1MHz signals, more filtering can be thrown at the finished unit without degrading in band performance.

You will also save the expense of the mechanical filters. 73 Alberto I2PHD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 8894 invoked from network); 8 Jan 2001 10:42:11 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by 10.226.25.101 with SMTP; 8 Jan 2001 10:42:11 -0000 Received: (qmail 8417 invoked from network); 8 Jan 2001 10:45:32 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 8 Jan 2001 10:45:32 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14FZiS-0004sZ-00 for rsgb_lf_group-outgoing@blacksheep.org; Mon, 08 Jan 2001 10:39:52 +0000 Received: from mail3.svr.pol.co.uk ([195.92.193.19]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14FZiR-0004sU-00 for rsgb_lf_group@blacksheep.org; Mon, 08 Jan 2001 10:39:51 +0000 Received: from modem-101.ar-pharazon.dialup.pol.co.uk ([62.136.127.101] helo=lvm) by mail3.svr.pol.co.uk with smtp (Exim 3.13 #0) id 14FZiG-0001V2-00 for rsgb_lf_group@blacksheep.org; Mon, 08 Jan 2001 10:39:41 +0000 Message-ID: <000101c0795f$cc5747e0$657f883e@lvm> From: "LAWRENCE MAYHEAD" To: "rsgb lf group" Subject: LF: Re.

For the IF gain the Analog Devices AD603, has 0-40dB gain with a voltage control of 0-1 V, laser trimmed for 0.3dB linearity so a voltmeter can be used to read off gain setting. No AGC will be used, and a switchable 20dB attenuator for strong in passband signals. By operating the front end device (a MAR-3 modamp) at constant current and employing an SRA3H diode ring mixer with 50mW of LO signal, the whole Rx can be made immune to temperature variation and supply voltage changes, whilst keeping a sufficiently good dynamic range. Haven't decided on the detector mixer device yet, but an NE612 or similar mixer will probably do, and the rest of the gain, at audio frequencies, will be simple op-amp circuitry before feeding into a 12bit A/D converter and possibly an audio amplifier. Any residual temperature/gain variation can be taken out with a thermistor and conditioning circuit applied to the AGC. IF filtering will be a 300Hz bandwidth mechanical filter at 455kHz. Very extensive front end filtering is needed to remove the image response which sits in the MF broadcast band at 910 - 1070kHz. 130dB in total apportioned into two filter blocks either side of the front end gain stage, Fc at 160kHz so that the 198kHz Droitwich signal is attenuated by 20dB before it reaches the mixer. Needless to say, all LO frequencies will be derived from one master 5MHz source. All in the future at the moment - the shack is still in bebuild.

Take minimum bearing with a loop (or ferrite) antenna, with that you get 2 possible directions (opposite to each other) 2. Sum the signal from the loop with the signal from a small electric antenna (piece of wire). The small electric antenna has an omnidirectional pattern, while the loop has an 8-shaped pattern. If both are summed you get a cardioid pattern (because both lobes of the loop pattern are opposite in phase). The null and maximum of the cardioid are far too wide to do an accurate bearing, but it is good enough to determine which of the 2 directions (determined with the loop) is the good one. remarks : A. Remind that for step 2 you have to turn the loop 90 degrees (the nulls of the 8-shaped pattern are in right angles to the loop plane while the maximum/minimum of the cardioid pattern are in the loop plane). B. you get the best F/B ratio on the cardiod pattern when the signal from both antennas have (abou) the same strength). 73, Rik ON7YD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 24338 invoked from network); 8 Jan 2001 09:21:56 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by excalibur.plus.net with SMTP; 8 Jan 2001 09:21:56 -0000 Received: (qmail 1468 invoked from network); 8 Jan 2001 09:16:31 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 8 Jan 2001 09:16:31 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14FYFP-0004Na-00 for rsgb_lf_group-outgoing@blacksheep.org; Mon, 08 Jan 2001 09:05:47 +0000 Received: from kauha.saunalahti.fi ([195.197.53.227]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14FYFL-0004NV-00 for rsgb_lf_group@blacksheep.org; Mon, 08 Jan 2001 09:05:43 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from default (MDCIV.tdyn.saunalahti.fi [195.197.83.204]) by kauha.saunalahti.fi (8.10.1/8.10.1) with SMTP id f0895pn29012 for ; Mon, 8 Jan 2001 11:05:51 +0200 (EET) Message-ID: <3.0.6.32.20010108110601.0080ecb0@pop.saunalahti.fi> X-Sender: vaiski1@pop.saunalahti.fi (Unverified) X-Mailer: QUALCOMM Windows Eudora Light Version 3.0.6 (32) Date: Mon, 08 Jan 2001 11:06:01 +0200 To: rsgb_lf_group@blacksheep.org From: =?iso-8859-1?Q?V=E4in=F6_Lehtoranta?= Subject: LF: Fs Measurements by OH2LX, 08-Jan-2001 MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Fs in dB(uV/m) by OH2LX, abt 2035z (99=Nil): >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> kHz;25dec;26dec;27dec;28dec;29dec;30dec;31dec;01jan;02jan;03jan;04jan;05jan; 06jan;07jan 057.7;99;99;99;99;99;99;99;99;99;99;99;99;99;99 060.0;50;52;53;53;52;52;51;48;50;53;53;52;49;52 068.0;55;51;52;55;53;53;54;51;52;49;52;53;48;52 068.9;58;56;59;57;52;38;53;52;53;55;55;53;54;99 073.2;43;45;45;47;43;44;43;43;45;47;47;46;42;42 075.0;43;45;43;43;37;46;42;40;42;43;42;36;39;39 077.5;54;60;57;58;54;56;56;53;55;55;60;54;54;50 128.9;50;54;52;49;32;35;44;46;48;46;47;45;45;41 138.8;49;50;55;51;42;43;38;49;51;53;54;51;48;42 135.8;14;26;31;20;18;19;14;23;28;24;25;24;23;17 137.0;99;99;99;99;99;99;99;99;05;99;99;99;99;99 016.0;53;55;53;55;54;55;52;54;51;53;52;51;51;51 018.3;59;61;99;60;58;59;59;59;60;58;57;56;57;56 023.4;99;99;99;99;99;99;99;99;99;99;99;65;66;62 024.0;53;53;51;49;50;49;49;46;48;47;48;47;46;46 ;;Day;25;26;27;28;29;30;31;01;02;03;04;05;06;07 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Day;Time;Call;Fs 25dec;0347;MM0ALM;18 25dec;0423;MM0ALM;15 25dec;0440;MM0ALM;17 26dec;2024;DJ9IE;-5 27dec;2114;DJ9IE;-4 27dec;2120;DJ9IE;-3 27dec;2128;DJ9IE;-4 27dec;2122;DJ8WX;-0 28dec;2027;ON6ND;-3 30dec;2115;OH1BS;18 01jan;2128;OH1BS;17 04jan;1923;SM6PXJ;+9 04jan;1925;SM6PXJ;10 04jan;2117;DJ9IE;-4 05jan;2002;ON6ND;-1 05jan;2009;ON6ND;-0 05jan;2026;ON6ND;-2 06jan;2234;OH1BS;17 06jan;2250;OH1BS;17 06jan;2236;DJ8WX;-2 06jan;2251;MM0ALM;+6 07jan;2059;G3XTZ;-4 07jan;2106;SM6PXJ;-1 07jan;2119;SM6PXJ;+3 07jan;2121;G3XTZ;-5 07jan;2129;OH1TN;21 07jan;2130;SM6PXJ;-2 07jan;2133;SM6PXJ;-1 07jan;2135;SM6PXJ;+1 07jan;2134;OH1TN;19 ------------------------------------------------------- (R&S ESH2/-----10m coax----->/1:10/-----15m wire-----): Noise level (136.2-136.9) with antenna, in 200Hz IF Bw: -26..-24 dB(uV)-> estim.

The fact is that the program is optimized for weak, very weak, signals, and the last mods to the AGC routine are a further step in that direction. So, with strong signals Argo is blinded, so to speak. The AGC function is not reversed. Probably you were in a condition of low noise and strong signal, and this new AGC compares the strength of the signal to the background noise level to compute the brightness to put on the screen. Build 110 used a different method.

This reduces the bandwith to 1/3rd or 1/6th of the original PSK31 signal, and thanks to the nice coding scheme used in PSK31, the character transmission speed is still acceptable for a 'real' QSO. ( For those who are not familiar with PSK31: It uses a code set called 'Varicode', which uses fewer bits for frequent letters like 'e' than the others, similar to the Morse code.) To test the effect of the reduced symbol rates, I added white noise to the signal and compared the decoded text with the original PSK31. I decreased the signal/noise ratio until the decoded text became undetectable. The results were as expected: Using "PSK10" instead of "PSK31", the noise could be increased about 3 times in amplitude for the same detection quality. However, if you want to test the 'slow PSK31 variants' on air. Because all PSK31 programs I had did not support other symbol rates than 31.25sym/sec, I modfied the PSK modulator and detector from WinPSK (by AE4JY) and stuffed them into Spectrum Lab. I just uploaded a new release of SpecLab (V1.63) with a built-in 'digimode terminal'. It is available at www.qsl.net/dl4yhf/spectra1.html. Beta testers are welcome. Bug reports please to DL4YHF@qsl.net. How about some 'QRPP' tests, Geri ? ------------ snip ------------ Drifting frequency of DF0WD's CW signal: The problem is a result of the poor stability of the main oscillator in my old Icom IC706. The fan blows warm air from the final amp towards the 'master crystal'. I watched the Loran lines yesterday, and found them 'wandering' around the sreen for about 30 seconds after one over (using only normal CW here). I thought about buying a 'TCXO' for the IC706, but the cost of about 120euro for that tiny piece of PCB kept me off. Any better ideas ? ----------- snip ----------- 73's Wolf (DL4YHF, qrv on LF only from DF0WD).

new features: 1. It can key TX, similarly like Rik's QRS (the same interface, of course). It is possible to let the keying run round with some delay, it is possible to set small PTT -> key delay, it is possible to pause scanning while tranmitting or use QSK mode. It is possible to pause current transmission to change some parameters or the text and then continue. If you use another "gram" program, you can use only keying portion from EasyGram. 2. Pictures can be now saved as JPEG files also, you can set quality of the picture or set it black&while only. 3. Saved pictures can be renamed or "saved as" to be copied to a different directory. 4. It is distinguished by color which settings belong to a profile and which are global, that are saved when EasyGram is terminated. For them who had problems with download: from Tuesday next week it will be available also at: http://www.sweb.cz/www/ok1fig/EasyGram.htm (case sensitive!) Any feedback or bug report is welcome. 73 Petr OK1FIG From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 26456 invoked from network); 7 Jan 2001 10:04:08 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by extortion.plus.net with SMTP; 7 Jan 2001 10:04:08 -0000 Received: (qmail 4296 invoked from network); 7 Jan 2001 10:06:44 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 7 Jan 2001 10:06:44 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14FCZT-0007SU-00 for rsgb_lf_group-outgoing@blacksheep.org; Sun, 07 Jan 2001 09:57:03 +0000 Received: from mail11.svr.pol.co.uk ([195.92.193.23]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14FCZS-0007SP-00 for rsgb_lf_group@blacksheep.org; Sun, 07 Jan 2001 09:57:02 +0000 Received: from modem-7.barahir.dialup.pol.co.uk ([62.136.134.135] helo=lvm) by mail11.svr.pol.co.uk with smtp (Exim 3.13 #0) id 14FCZF-0006OR-00 for rsgb_lf_group@blacksheep.org; Sun, 07 Jan 2001 09:56:49 +0000 Message-ID: <000201c07890$a4cd0fe0$8786883e@lvm> From: "LAWRENCE MAYHEAD" To: "rsgb lf group" Subject: LF: Re.

You do not try to get a lock up in 64 microseconds (one frame). In this case the PLL is not trying to compensate for poor short term stability. The short-term stability of the VCO must be excellent. My Droitwich standard can take up to 20 minutes to reach lock after switch-on. The VCO is a very stable VXO which still have reasonable performance when the locking signal disappears. I think you must consider trading time for accuracy. A good PLL should always have the best VCO you can get to reduce the incidental FM. So over 10 minutes of nudging it in the right direction (not compensating for its short term stability) it is easy to see you can get 1000 times (at least) better performance. As you say there will always be a slight error, but it can be made vanishingly small.

The thought occurs to me that we should make an effort to contact ALM before next weekend, so that he knows about the Transatlantic effort. It would be a pity to waste all the efforts being made.

Is this an indication that the ground losses are in the immediate vicinity of the coil? 73, John, G4CNN _______________________________________________________ Send a cool gift with your E-Card http://www.bluemountain.com/giftcenter/ From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 10033 invoked from network); 6 Jan 2001 22:19:18 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by 10.226.25.101 with SMTP; 6 Jan 2001 22:19:18 -0000 Received: (qmail 13182 invoked from network); 6 Jan 2001 22:22:35 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 6 Jan 2001 22:22:35 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14F1eR-0004rD-00 for rsgb_lf_group-outgoing@blacksheep.org; Sat, 06 Jan 2001 22:17:27 +0000 Received: from carbon.btinternet.com ([194.73.73.92]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14F1eR-0004r8-00 for rsgb_lf_group@blacksheep.org; Sat, 06 Jan 2001 22:17:27 +0000 Received: from [213.1.104.38] (helo=default) by carbon.btinternet.com with smtp (Exim 3.03 #83) id 14F1eH-0003cr-00 for rsgb_lf_group@blacksheep.org; Sat, 06 Jan 2001 22:17:17 +0000 Message-ID: <000301c0782e$633329a0$266801d5@default> From: "Alan Melia" To: rsgb_lf_group@blacksheep.org Subject: LF: VE1ZZ 136.5kHz Date: Sat, 6 Jan 2001 22:14:37 -0000 MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 4.72.3110.5 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Hi all, despite my noises Jack was an 'M' copy here at 2200z he is sitting on top of a 'qrm' line with me but most of each call was visible.

A few months ago, the best frequencies were LF of it, but it has now dropped below the band edge. I plan to be on 135.875kHz tonight, but can move anywhere else you want. 73 Mike, G3XDV From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 1429 invoked from network); 6 Jan 2001 19:30:33 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by extortion.plus.net with SMTP; 6 Jan 2001 19:30:33 -0000 Received: (qmail 2986 invoked from network); 6 Jan 2001 19:33:12 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 6 Jan 2001 19:33:12 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14Ez03-0004E5-00 for rsgb_lf_group-outgoing@blacksheep.org; Sat, 06 Jan 2001 19:27:35 +0000 Received: from smtp06.wxs.nl ([195.121.6.58]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14Ez00-0004Dz-00 for rsgb_lf_group@blacksheep.org; Sat, 06 Jan 2001 19:27:32 +0000 Received: from default ([195.121.222.67]) by smtp06.wxs.nl (Netscape Messaging Server 4.05) with SMTP id G6RA0S04.DUZ for ; Sat, 6 Jan 2001 20:26:52 +0100 Message-ID: <001801c07816$87b0d2e0$43de79c3@default> From: "ko versteeg" To: rsgb_lf_group@blacksheep.org Subject: LF: Re: URL for Argo Date: Sat, 6 Jan 2001 20:26:10 +0100 MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 4.72.3110.1 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Hi all..

Dave G3YXM. Very sorry to hear of your disaster, Dave. Many of us have had fires associated with our LF activities, though none quite as bad as that. I once went out in the car leaving my 73kHz Tx beaconing, and an hour later was puzzled that the signal had stopped. A call to my son revealed that he switched it off when smoke came from the plastic (!) drain pipe of our brand new conservatory as the wind blew the antenna wire onto it. I also burnt a hole in the mat on the floor of my car when I put a portable loading coil on it. I admit to being very nervous about running 700W RF overnight. I think I will move the smoke detector closer to the rig now. I wonder what an insurance investigator would make of amateur radio practice. Hope you get it all restored shortly. 73 Mike, G3XDV. http://www.lf.thersgb.net From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 6497 invoked from network); 6 Jan 2001 18:21:54 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by excalibur.plus.net with SMTP; 6 Jan 2001 18:21:54 -0000 Received: (qmail 2538 invoked from network); 6 Jan 2001 18:16:30 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 6 Jan 2001 18:16:30 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14ExoH-0003wQ-00 for rsgb_lf_group-outgoing@blacksheep.org; Sat, 06 Jan 2001 18:11:21 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from d12lmsgate-3.de.ibm.com ([195.212.91.201]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14ExoG-0003wL-00 for rsgb_lf_group@blacksheep.org; Sat, 06 Jan 2001 18:11:20 +0000 Received: from d12relay02.de.ibm.com (d12relay02.de.ibm.com [9.165.215.23]) by d12lmsgate-3.de.ibm.com (1.0.0) with ESMTP id TAA90558 for ; Sat, 6 Jan 2001 19:10:40 +0100 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from usa.net (ss7.bld.socks.ibm.com [9.14.4.72]) by d12relay02.de.ibm.com (8.8.8m3/NCO v4.95) with ESMTP id TAA101914 for ; Sat, 6 Jan 2001 19:10:38 +0100 Message-ID: <3A575F7E.ABB60AFE@usa.net> Date: Sat, 06 Jan 2001 19:10:06 +0100 From: "Alberto di Bene" Organization: Undisclosed X-Mailer: Mozilla 4.76 [en] (Win95; U) X-Accept-Language: en MIME-Version: 1.0 To: "LF Mailing List" Subject: LF: URL for Argo Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 8bit Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: If you experience difficulties in downloading the latest build of Argo, please be patient.

I can see that you all are correct. There is much more energy between 135.7 and 135.8 than there is between 135.9 and 136.0 THEREFOR:: please transmit QRSS sigs from EU between 135.9 and 136.0 . I checked Loran lines this AM If you add200 Hz to your 135.7 kHz freq we should be OK I don't know what I see from Jack's House I will have E_MAIL there. If CFH is transmitting and I see more crap at 135.9 I may ask you all to QSY back down to 135.7. But for this week lets try 135.9 up. Last night I watched until 0730 SVX was big at 1357.7 or so. DCF39 was S-7 between 2327 and 2400. Ihad to leave between 0030 and 0300. AT 0300 128.9 was S-5 . IT rose to S-6 between 0356 and 0422. At 0422 it was S-3 falling to S-1 at 0520. It came peaking at 0715 at S-6. I thought I saw dashes from G3XTZ from 0625 I lost them at 0641. SXV disappeared at 0614. It is conceivable that I had trouble with 1 watt erp sigs in fall due to SXV . I saw it often but didn't realize what it was until I put on the earphones one night and heard the a RTTY . The lower freq of SXV is below 135.7 and it is not on my screen 73 de John VE1ZJHope to see you tonight pse EMAIL FREQ From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 13828 invoked from network); 6 Jan 2001 17:23:21 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by 10.226.25.101 with SMTP; 6 Jan 2001 17:23:21 -0000 Received: (qmail 27588 invoked from network); 6 Jan 2001 17:26:38 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 6 Jan 2001 17:26:38 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14Ex0P-0003hL-00 for rsgb_lf_group-outgoing@blacksheep.org; Sat, 06 Jan 2001 17:19:49 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from finch-post-10.mail.demon.net ([194.217.242.38]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14Ex0O-0003hG-00 for rsgb_lf_group@blacksheep.org; Sat, 06 Jan 2001 17:19:48 +0000 Received: from alg.demon.co.uk ([194.222.171.80]) by finch-post-10.mail.demon.net with esmtp (Exim 2.12 #1) id 14Ex0E-0002rB-0A for rsgb_lf_group@blacksheep.org; Sat, 6 Jan 2001 17:19:39 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Message-ID: <3A5753FC.B08BF660@alg.demon.co.uk> Date: Sat, 06 Jan 2001 17:21:00 +0000 From: "Steve Rawlings" X-Mailer: Mozilla 4.6 [en-gb]C-CCK-MCD NetscapeOnline.co.uk (Win98; I) X-Accept-Language: en-GB,en MIME-Version: 1.0 To: rsgb_lf_group@blacksheep.org Subject: Re: LF: Fire!

Seriously though, thanks for sharing your unfortunate experience. You're not the first to have their LF loading coil catch fire (and I doubt that I was the first, either), so it is a timely reminder for all those using indoor loading coils (or loading coils close to the house) to be especially careful. I hope that you can re-build the loading coil and ATU hut soon.

I am surprised that Jack's signal is so consistant here on the south coast when it may not be so in other parts of the country. I read an article in CQ that suggested that transatlantic 160m signals took a much more southerly route that was first thought. At various times G3AQC, G3XTZ, G3YXM and G3XDV were transmitting below 136kHz; G3AQC and G3XTZ embedded in the SXA RTTY signal. At around 1245 the SXA signal disappeared leaving all the G stations in the clear.

O'Brien (see below). Under http://users.mesatop.com/~ghansen/ you can find a new PSK31/RTTY/ASCII, etc. program for Soundblaster use, that was written by KD5HIO. This program contains some experimental type of forward error correction (FEC) to the various modes. Also MFSK16 and a mode called HFSK16 is implemented. These modes use a variety of tones, bandwidth is in the range of 250 Hz. Markus, DF6NM and I have tested PSK31 and since Markus' signal is just in the region of my local noise level, plus the normal QRN that we have on LF make normal PSK31 only 70% succesful, we have recently tested QPSK. Obviously receprion was a little bit better using that mode. We plan to check the other modes, too, in the next couple of days to find the most reliable way of keyboard-to-keyboard for weak s/n ratio signals. So if you hear some strange signals, tones, etc. on and around 137.500 kHz, this is most probably us. I will enable CW-identification. Besides that, I still run normal CW from time to time and had a nice first QSO with HB9DCE this morning.

PAL colour subcarrier is also a deliberately interleaved frequency with a 25 Hz offset, so is another "lovely combination" and hardly suited for direct locking to a standard 5 or 10 MHz oscillator. I'm not sure if there is any German satellite TV downunder, but there is a terrestrial German UHF channel here in Wellington, with international programme content, so it could be reticulated by satellite? Of course, another factor with using an off-air radio signal as a frequency reference is that the receiver would not want to be interfered with by any on-site amateur transmission, especially if it was used to lock the frequency of that transmitter :-) 73, Bob From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 18650 invoked from network); 6 Jan 2001 06:02:21 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by excalibur.plus.net with SMTP; 6 Jan 2001 06:02:21 -0000 Received: (qmail 10591 invoked from network); 6 Jan 2001 05:57:00 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 6 Jan 2001 05:57:00 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14EmAB-0001CG-00 for rsgb_lf_group-outgoing@blacksheep.org; Sat, 06 Jan 2001 05:45:11 +0000 Received: from imo-r08.mx.aol.com ([152.163.225.8]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14EmA9-0001CB-00 for rsgb_lf_group@blacksheep.org; Sat, 06 Jan 2001 05:45:10 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from WarmSpgs@aol.com by imo-r08.mx.aol.com (mail_out_v28.35.) id l.f7.652f049 (3974) for ; Sat, 6 Jan 2001 00:44:14 -0500 (EST) From: WarmSpgs@aol.com Message-ID: Date: Sat, 6 Jan 2001 00:44:13 EST Subject: Re: LF: RE: Freq stability To: rsgb_lf_group@blacksheep.org MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII; format=flowed Content-Transfer-Encoding: 8bit X-Mailer: AOL 4.0 for Windows 95 sub 120 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: In a message dated 1/4/01 3:42:49 AM Eastern Standard Time, ACTALBOT@dera.gov.uk writes: << Can you get German satellite TV over there ?

Of course no Loran lines can be seen with this antenna. The captured screens, with the Greek RTTY in all its glory, are here : http://www.qsl.net/i2phd/argo/greek.html >From what I can see here, in my location, the quietest spot below 136 kHz is around 135.9 kHz My apologies for my previous post in HTML. I didn't think it could be of nuisance to somebody. 73 Alberto I2PHD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 19261 invoked from network); 5 Jan 2001 22:53:53 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by extortion.plus.net with SMTP; 5 Jan 2001 22:53:53 -0000 Received: (qmail 29429 invoked from network); 5 Jan 2001 22:56:28 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 5 Jan 2001 22:56:28 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14Efef-00087A-00 for rsgb_lf_group-outgoing@blacksheep.org; Fri, 05 Jan 2001 22:48:13 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from mailout04.sul.t-online.com ([194.25.134.18]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14Efec-000875-00 for rsgb_lf_group@blacksheep.org; Fri, 05 Jan 2001 22:48:10 +0000 Received: from fwd06.sul.t-online.com by mailout04.sul.t-online.com with smtp id 14EfeJ-0007Fd-05; Fri, 05 Jan 2001 23:47:51 +0100 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from (0482183881-0001@[62.157.30.219]) by fwd06.sul.t-online.com with smtp id 14EfeF-1MUPgWC; Fri, 5 Jan 2001 23:47:47 +0100 From: "jannsen" <0482183881-0001@t-online.de> To: rsgb_lf_group@blacksheep.org Subject: LF: G3XDV X-Mailer: T-Online eMail 2.34 MIME-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 8bit Date: Fri, 5 Jan 2001 23:47:47 +0100 Message-ID: <14EfeF-1MUPgWC@fwd06.sul.t-online.com> X-Sender: 0482183881-0001@t-dialin.net Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: hi g3xdv reading harry potter wilst scanning lf just caught you looking up with "o", outstanding signal! vy 73 Uwe/DJ8WX (qsl.net/dj8wx - dj8wx@qsl.net) From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 9162 invoked from network); 5 Jan 2001 21:01:42 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by extortion.plus.net with SMTP; 5 Jan 2001 21:01:42 -0000 Received: (qmail 13440 invoked from network); 5 Jan 2001 21:04:17 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 5 Jan 2001 21:04:17 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14Edw6-0007hN-00 for rsgb_lf_group-outgoing@blacksheep.org; Fri, 05 Jan 2001 20:58:06 +0000 Received: from jubilee.ns.sympatico.ca ([142.177.1.6]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14Edw4-0007hI-00 for rsgb_lf_group@blacksheep.org; Fri, 05 Jan 2001 20:58:04 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from ns.sympatico.ca ([142.177.87.188]) by jubilee.ns.sympatico.ca (Post.Office MTA v3.5.2 release 221 ID# 0-68925U141000L141000S0V35) with ESMTP id ca for ; Fri, 5 Jan 2001 16:57:46 -0400 Message-ID: <3A567BCB.7D69C0A5@ns.sympatico.ca> Date: Fri, 05 Jan 2001 20:58:35 -0500 From: "John Currie" X-Mailer: Mozilla 4.7 [en]C-DIAL (Win95; U) X-Accept-Language: en MIME-Version: 1.0 To: rsgb_lf_group@blacksheep.org Subject: Re: LF: Re: Spectrum of SXA/SXV References: <23786748.978711341513.JavaMail.imail@bubbles.excite.com> <3A56048F.99CCECAF@usa.net> Content-Type: multipart/mixed; boundary="------------060509030105020208000900" Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: This is a multi-part message in MIME format. --------------060509030105020208000900 Content-Type: text/html; charset=windows-1252 Content-Transfer-Encoding: 8bit Hi Alberto,   Can you please send me Spectrum plot of Greek station .  The plot should start at 135.6 kHz and end at 136.0 kHz .  I am most interested in comparison  of 135.7-135.8  segment with the 135.9 -136.0 segment .

Hi All,
I find the noise spectrum of this station to have the following structure:
135.670 - 135.678 very dense
135.678 - 135.75 density reduces to almost nothing ?
135.75 - 135.767 density again increases
135.767 - 135.775 very dense
[snip]
Here is how that portion of the spectrum looks like here in Italy.
The RX was tuned to 135 kHz, so what you read on the scale 
is the offset.

The maker of my locked standard is understandably coy about quoting a figure. I must say I was very pleased with the way the trace moved smoothly across the screen over the test period, no sign of short-term instabilities. I suppose averaged over about 1000secs most of the problems disappear. I have had a quick look through my Elektor index and can't find the TV sync 'standard'.

Hi All,
I find the noise spectrum of this station to have the following structure:
135.670 - 135.678 very dense
135.678 - 135.75 density reduces to almost nothing ?
135.75 - 135.767 density again increases
135.767 - 135.775 very dense
[snip]
Here is how that portion of the spectrum looks like here in Italy.
The RX was tuned to 135 kHz, so what you read on the scale 
is the offset.

Curiously it is quietest somewhat HF of the centre at about 135.75, nature of the data I suppose. Trying to get an amateur signal through the centre of this, seems pretty unlikely. The fact that it doesn't trouble the Canadians is probably bad news for us rather than the other way round. 73, John, G4CNN _______________________________________________________ Send a cool gift with your E-Card http://www.bluemountain.com/giftcenter/ From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 5200 invoked from network); 5 Jan 2001 15:25:10 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by 10.226.25.101 with SMTP; 5 Jan 2001 15:25:10 -0000 Received: (qmail 7161 invoked from network); 5 Jan 2001 15:28:29 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 5 Jan 2001 15:28:29 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14EYhu-0006Jp-00 for rsgb_lf_group-outgoing@blacksheep.org; Fri, 05 Jan 2001 15:23:06 +0000 Received: from bucky-rwcmex.excite.com ([198.3.99.218] helo=bucky.excite.com) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14EYht-0006HT-00 for rsgb_lf_group@blacksheep.org; Fri, 05 Jan 2001 15:23:05 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from bubbles.excite.com ([199.172.153.29]) by bucky.excite.com (InterMail vM.4.01.02.39 201-229-119-122) with ESMTP id <20010105152219.DSYW25756.bucky.excite.com@bubbles.excite.com> for ; Fri, 5 Jan 2001 07:22:19 -0800 Message-ID: <4904533.978708139615.JavaMail.imail@bubbles.excite.com> Date: Fri, 5 Jan 2001 07:22:18 -0800 (PST) From: "john sexton" To: rsgb_lf_group@blacksheep.org Subject: Re: LF: RE: LF Spurious signal on south coast MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 8bit X-Mailer: Excite Inbox X-Sender-Ip: 62.253.64.5 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Hi Andy, Just seen your correction.

It gives me a slight problem receiving the VA.. 137.79 transmission as the carrier is close enough that even in a 300Hz filter bandwidth it depresses the RA1792 AGC a little. I'll try setting up the loop this weekend and do a DF on it. Now you mention it, do remember commenting on this earlier and forgotton. Decided to give high power amplifiers a break for now as the 600 - 700W PA is completed. Next project is a proper LF receiver with accurate and repeatable signal measuring capability and built in A/D converter to avoid having to use soundcards or external DSP for narrow band working. I've identified all the analogue component stages and gain distribution, and designed it on paper, just need to put it together now to give a /P LF receiving capability that would allow driving around to DF the signal. I've just started rebuilding the shack at the moment, moving fitted cupboards to the other end and putting in a proper run of decent benches along two walls with built in 19" equipment racking space, so major constructional projects are on hold for a few weeks. The computer has been moved downstairs so any radio - computer interfacing means long coax cables between rooms for now.

Does anyone else see a carrier on 136744.6.  It is particularly strong at my QTH (IO90IV58), on continuously and too stable to be a spurious from SMPSU, TV etc.

Like you I am concerned about transmitting within the RTTY signal.

Jack was also R 'O' here (at the same times as reported by Laurie) just using a G3LNP type loop couped to the receiver via a two-turn loop and 45m of coax and no amplifier (much to my surprise). The loop is set to null Loran -first time I have seen weak signals without Loran lines. Using Argo beta 1, build 113. Argo has an AGC on/off facility; when off minimises very strong signals desensitising the soundcard. Laurie is S9+35dB with me on my transmitting antenna but I now have a receive system that can monitor strong signals yet see the very weak ones at the same time provided there is at least 500Hz of separation between the weak and strong signals. I set the receiver to 136kHz SSB USB. Argo, on 'Full Band View'. The band from 136.0 to 137.5kHz can be seen and any signal can be selected and zoomed, a wonderful tool for monitoring. The strong signals from Laurie and Mike, below 136kHz are seen as an image folded just above 136kHz; their frequencies can be read off as minus 136kHz on the Argo frequency scale. -- Regards, Peter, G3LDO From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 7684 invoked from network); 5 Jan 2001 11:36:51 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by extortion.plus.net with SMTP; 5 Jan 2001 11:36:51 -0000 Received: (qmail 19042 invoked from network); 5 Jan 2001 11:39:28 -0000 Content-Transfer-Encoding: 8bit Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 5 Jan 2001 11:39:28 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14EV8B-0005HJ-00 for rsgb_lf_group-outgoing@blacksheep.org; Fri, 05 Jan 2001 11:33:59 +0000 Received: from mail.cc.kuleuven.ac.be ([134.58.10.6]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14EV8A-0005HE-00 for rsgb_lf_group@blacksheep.org; Fri, 05 Jan 2001 11:33:58 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from LCBD15.fys.kuleuven.ac.be (LCBD15.fys.kuleuven.ac.be [134.58.80.15]) by mail.cc.kuleuven.ac.be (8.9.3/8.9.0) with SMTP id MAA1023104 for ; Fri, 5 Jan 2001 12:33:49 +0100 Message-ID: <3.0.1.16.20010105132517.2b471cee@mail.cc.kuleuven.ac.be> X-Sender: pb623250@mail.cc.kuleuven.ac.be X-Mailer: Windows Eudora Pro Version 3.0.1 (16) Date: Fri, 05 Jan 2001 13:25:17 To: rsgb_lf_group@blacksheep.org From: "Rik Strobbe" Subject: Re: LF: Re.

Taking into account that SXV is abt 1000km east and 1600km south of central UK it might be less of a problem in Cananda than we think. My impression is that the UK-VE path is already 6dB to 10dB better than the ON-VE path, so the SV-VE path might well be 30dB or more down on the UK-Ve path. 73, Rik ON7YD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 23335 invoked from network); 5 Jan 2001 11:21:05 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by excalibur.plus.net with SMTP; 5 Jan 2001 11:21:05 -0000 Received: (qmail 16894 invoked from network); 5 Jan 2001 11:15:44 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 5 Jan 2001 11:15:44 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14EUl0-0005Cw-00 for rsgb_lf_group-outgoing@blacksheep.org; Fri, 05 Jan 2001 11:10:02 +0000 Received: from cmailg2.svr.pol.co.uk ([195.92.195.172]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14EUkz-0005CU-00 for rsgb_lf_group@blacksheep.org; Fri, 05 Jan 2001 11:10:01 +0000 Received: from modem-49.belfalas.dialup.pol.co.uk ([62.136.139.49] helo=lvm) by cmailg2.svr.pol.co.uk with smtp (Exim 3.13 #0) id 14EUkp-00039U-00 for rsgb_lf_group@blacksheep.org; Fri, 05 Jan 2001 11:09:51 +0000 Message-ID: <000101c07708$83ec0260$318b883e@lvm> From: "LAWRENCE MAYHEAD" To: "rsgb lf group" Subject: LF: Re.

Can I suggest that the VE stations check the frequencies to see wether 135.670-135.780 is more noisy than the alternative band above 135.900. Obviously increased noise will reduce the possibilities of getting a signal across. I look foreward to us resolving this problem,Hi. 73s Laurie.

I make it 135.673 and 135.773kHz with a lot of noise in between. Using frequencies in the 135.7 region (ie the middle of the RTTY) is a bit like Canadian stations transmitting on 137.000. Is this really a good idea? I would have thought that even the noise sidebands from SXV would be very significant compared to Eu amateurs. I have attached a small JPG to illustrate this. The band edge is in the middle of the noise and the clear section is below the RTTY (HF) between 135.850 and the line which is on 136.000. It is really up to John, Jack and Larry to say where they prefer to listen, but the area currently in use looks really bad from this end.

All received datafiles were averaged in 1 minute periods, to surpress static crashes etc... 2. All datafiles were 'shifted' to an average value of -30dB (relative), since all measurements (except for Alan) were relative As a result of 2. you cannot compare the absolute strength of the data, just the trends. Very interesting is the 20 minute 'off period' of CHF just before midnight as this alows to determine the SNR (and that is after all the most important figure in practice). All data are available as an Excel file for those who want to have a closer look, just let me know by (direct) e-mail and I will sent you the file. 73, Rik ON7YD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 10034 invoked from network); 5 Jan 2001 09:03:59 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by excalibur.plus.net with SMTP; 5 Jan 2001 09:03:59 -0000 Received: (qmail 3134 invoked from network); 5 Jan 2001 08:58:40 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 5 Jan 2001 08:58:40 -0000 Content-Transfer-Encoding: 8bit Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14ESXW-0004a7-00 for rsgb_lf_group-outgoing@blacksheep.org; Fri, 05 Jan 2001 08:47:58 +0000 Received: from bob.dera.gov.uk ([192.5.29.90]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14ESXU-0004a2-00 for rsgb_lf_group@blacksheep.org; Fri, 05 Jan 2001 08:47:56 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: by bob.dera.gov.uk; (8.8.8/1.3/10May95) id IAA07417; Fri, 5 Jan 2001 08:48:46 GMT Received: (qmail 29838 invoked from network); 5 Jan 2001 09:42:08 -0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from gauntlet.mail.dera.gov.uk (172.16.9.10) by baton.dera.gov.uk with SMTP; 5 Jan 2001 09:42:08 -0000 Received: by gauntlet.mail.dera.gov.uk; id JAA05247; Fri, 5 Jan 2001 09:35:02 GMT Received: from unknown(10.71.64.31) by gauntlet.mail.dera.gov.uk via smap (3.2) id xma005221; Fri, 5 Jan 01 09:34:29 GMT Received: from FRN-MAIL-3.dera.gov.uk (unverified) by mailguard.dera.gov.uk (Content Technologies SMTPRS 4.1.5) with ESMTP id for ; Fri, 5 Jan 2001 08:49:47 +0000 Received: by frn-mail-3.dera.gov.uk with Internet Mail Service (5.5.2650.21) id ; Fri, 5 Jan 2001 08:47:13 -0000 Message-ID: <65AECDF1F89AD411900400508BFC869F0D74E5@pdw-mail-1.dera.gov.uk> From: "Talbot Andrew" To: rsgb_lf_group@blacksheep.org Subject: LF: RE: Freq Stabilityc Date: Fri, 5 Jan 2001 08:47:25 -0000 MIME-Version: 1.0 X-Mailer: Internet Mail Service (5.5.2650.21) Content-Type: text/plain; charset=iso-8859-1; format=flowed Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: The self contained TV reference I mentioned yesterday appeared originally, by DK2DB in a German publication and was translated by G7LEE for the RSGB Microwave Newsletter January 1996.

I only rated the signal 'T' until the last call-sign of the 2400z session came up out of the noise for an 'O'. I am seeing 2 faint lines under Jacks frequency. I am not sure whether they are Loran, or the DCF IMPs that Markus reported. They faded down at 2406z which allowed the dots to be resolved on the last complete call. Jack has been clear of qrm lines with me before and I think I recognise one of the two as a Loran line. I wonder if Jack has drifted about 1Hz higher over the last few days? I am not sure enough of the calibration to say.

(I have copies but will have to dig with the aid of an incomplete written index) 15.625 kHz is 1MHz/64 so an easy PLL circuit will lock a 1MHz VXO. I recollect a system which coupled to the scan coils by means of a pick-up coil on the outside of the TV cabinet. The TV needed to be on AND receiving a programme, of course. A technique I saw somewhere (maybe a Tek or HP App note) for freq comparisons suggested triggering a 'scope from the standard 1MHz (or 10MHz) signal and then timing the drift of a cycle the 'unknown' 1MHz (RACAL 9420 /5 in my case) across the screen with a stop watch. I have certainly calibrated counter timebases to parts in 10^10 (possibly optimistic as Droitwich is probably not that stable over 1000secs.....or is it?) by this technique. I have a Halcyon Off-air standard source, which offers the option of the French station at Allois.

The noise is fairly consistent, with the RX settings I am using the noise at 2300z measures usually about 12dBu droping to 6 or sometimes 4 dBu in the morning period just after dawn. I have a complete plot for one night, but it may not have been loaded (see 15th Dec). But this is measured in a 300Hz bandwidth. Now remember that my measurements are made with a detector time-constant of 3 seconds and I take 6 samples with the ADC at 10 sec intervals and only plot the lowest one. This is to avoid the effects of static 'crashes'. As to the periods of the fading. A careful look at my plots shows a number of different periods. Some of the rapid fade periods are as little as 5 to 10 minute cycles, but they do tend to be of relatively shallow amplitude. One of my hypotheses was that the difference on the plots from different sites was due to the same 'fourier elements' of the plot were summed with different phase relationships at different sites. The other fortunate point is that the rapid fades do not occur in general when conditions are good or improving. I believe that these conditions are when the propagation is just beginning to recover from the after-effects of a particle injection from a CME or Coronal hole event. The 'after-effects' last well beyond the time that the geomagnetic indexes (Ap and Kp) return to the 'quiet' state. Conditions are usually better a couple of days of so later, provided there is no further disturbance. The fast fades cease and just a couple of much slower period fades remain, it is these effects I believe that can push the signal from CFH up over 40dBu for a period of about 30 mins. I think from the results I have studied that on the best nights the period of the highest peaks might be of the order of about 30 minutes. As we move further away from a disturbed period the deep fades disappear, and there can be a fairly constant strength for the whole of the main part of the night (see 11th Dec), sometime only varying by say 6dB. These night do not show the highest peaks but have the longest consistently high signal.... maybe a good night for MS1000 or 10 sec dots !! I also think, although we have no measurements to prove it yet, that the signals get better as we move west and weaker as we move east (as might be expected) Riks plots do maybe suggest that anyone seriously considering tackling the path should try to get some kind of a 'handle' on expected levels of CFH at their location, if they want to utilise the effect of the constructive interference on multipath propagation. Rik's plots make a fascinating gallery. I have not managed to print them yet in a sensible format so that I can compare them at leisure. I rated the 18th a 'moderately disturbed' night, because there were lots of components to the profile. It would have been nice for me to have been able to take plots on succeeding nights to see the progress of the 'event' to its conclusion. It would have been interesting if we could have managed to get a plot from Brian, but I understand his aerials suffered in the gales. Thanks to all who took part.....we must do it again sometime !! Hopefully CFH will come back before too long so that I can continue my studies. I am a bit ambivalent about the timing .....I would like to be able to get some plots before and after the 12/14 weekend, but I am aware that the appearance of CFH again will make Jack and John's job a lot more onerous. Alas, I have no influence on the Canadian Navy. Good Luck all.

I have no idea if APRS is popular in Europe, I frankly dont know why APRS is popular at all, but there is a large and growing community of activity over here. Search them out on the Internet and keep in touch and make some inquiries and I am sure that others like myself last year, will find a source of receivers at a very low price. I have just spoken with a local, well 35 miles away, who is into APRS and he tells me that there were some very cheap GPS RX's around in early November - he thinks they were mentioned a few times on the TAPR APRS SIG (Special Interest Group).

Digging around the APRS groups on the Internet was important to finding these sources. I just tried the URL of the place I got mine from a year ago and it is no longer valid. > Not all handhelds have a 1pps output -.......

Agreed. The OEM units I have seen so far, Garmin 20 and 25 all have the 1 PPS (mine is blinking away as I write this). The Garmin 25 has a very nice feature in that you can set it to have Position Hold and the 1 PPS has some what less jitter than otherwise, about half the amount I am told. > The data bursts from its NMEA output were too > uncertain in their timing to even think of using as standard. Agreed. Although if you only want 2 or 3 Milliseconds accuracy you can do the following. Set the unit to send out only one line of data, I choose "GPRMC" Watch the RMC line for the 59th second to appear Then trip into your application program on the reception of the next "$" (dollar sign) which is the first character of the next string. I have a write-up that says the valid time event for that line occurs at the send of the second character in the string, I have no idea were I saw that. My work here of disciplining an older HP frequency standard will not permit a continuous string of 1 PPS pulses from the receiver so I have been gathering frequency drift rate data from the HP oscillator. My goal is to let the PC correct the Frequency Standard according to a known drift rate and to only make the 1 PPS available on say a weekly or even longer basis to bring the standard back into lock. This way I can use only one GPS receiver to keep several different frequency standards in high stability mode. The common curse of having three different transmitting locations hi. PS the OEM level receivers are "unpacked" and exceedingly hard to work on. It took me three tries to get an antenna connector in place that worked properly. Good Luck with hunting up a source of supply....

There was a circuit in Radcom a couple of years back, which seemed to be very similar to an Electronics Australia project from 1993. The composite video could come from a VCR rather than a TV set. Running an actual TV set in the shack would generally be shooting oneself in the foot for LF QRM :-( Also you likely need much better than a piece of wet string for the TV antenna, as noise or ghosting on the received video will not result in a lab standard for the reference signal. 73, Bob From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 10811 invoked from network); 4 Jan 2001 18:31:15 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by excalibur.plus.net with SMTP; 4 Jan 2001 18:31:15 -0000 Received: (qmail 23739 invoked from network); 4 Jan 2001 18:25:55 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 4 Jan 2001 18:25:55 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14EEye-0000x7-00 for rsgb_lf_group-outgoing@blacksheep.org; Thu, 04 Jan 2001 18:19:04 +0000 Received: from irwell.zetnet.co.uk ([194.247.47.48] ident=root) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14EEyb-0000x2-00 for rsgb_lf_group@blacksheep.org; Thu, 04 Jan 2001 18:19:02 +0000 Received: from oemcomputer (man-009.dialup.zetnet.co.uk [194.247.41.11]) by irwell.zetnet.co.uk (8.9.3/8.9.3/Debian/GNU) with SMTP id SAA03640 for ; Thu, 4 Jan 2001 18:18:51 GMT X-Authentication-Warning: irwell.zetnet.co.uk: Host man-009.dialup.zetnet.co.uk [194.247.41.11] claimed to be oemcomputer Message-ID: <006601c0767b$3e0f02c0$0b29f7c2@oemcomputer> From: "John Rabson" To: rsgb_lf_group@blacksheep.org References: <3A531C89.2032.BB2276@localhost> <3A54B293.13773.446063@localhost> Subject: Re: LF: Large and small antennas Date: Thu, 4 Jan 2001 18:22:01 -0000 MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.00.2615.200 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: ----- Original Message ----- From: Mike Dennison To: Sent: Thursday, January 04, 2001 5:27 PM Subject: Re: LF: Large and small antennas > Well, here we get into the very muddy waters of just how you > measure ERP - seemingly a very imprecise science.

Couple a sample of the signal source into the antenna circuit when the receiver is tuned to the broadcast frequency, and juggle the level of source and/or broadcast signals so they are approximately equal. Hopefully both signals will be within a fraction of a hertz of one another, so will appear superimposed as a single line on the spectrogram. However, as they drift in and out of phase, there will be peaks and nulls in the combined signal level. The frequency difference is the reciprocal of the period in seconds between 2 successive peaks or nulls, which can be measured with the cursor. If you choose an appropriate spectrogram time-base, and leave the set-up running for 1/2 an hour or so, it is easy to measure difference frequencies of the order of 0.001Hz, which is 5 parts in 10e9 at 198kHz. The only slight problem is that it does not tell you whether the difference is positive or negative, but that can be found by trial and error adjustment. I have tried this with 198kHz; also the Loran "carrier" at exactly 100kHz works, and might be more convenient if your reference signal is at a fixed frequency like 10MHz. Another possibility is to use a decade divider chain to obtain 1kHz from the reference; the harmonics in the LF range will be strong enough to make the comparison to an "odd" broadcast frequency. I was interested to see Rik's plots of the results from the CFH logging session (http://www.qsl.net/on7yd/t181200.htm) - as G3NYK suggested, deep fades do occur at different times at the different locations. The relative signal levels between different receive locations vary rapidly, so it is very likely that one person will be seeing nothing whilst their neigbor is getting good copy of a transatlantic signal. This suggests to me that, with marginal signals, there is not much point in going to very long dot lengths, or using very long "grab" sequences with BPSK software, since the signal will probably fade in and out in the time it takes to send a callsign. The propagation on LF seems to get more and more volatile as the distance increases It might be interesting if Alan were to make some plots with his logging gear while CFH is off-air (or on a different frequency when it comes back on again) of the noise level for comparison; after all, it is the signal to noise ratio which determines whether a signal can be received or not.

Well, here we get into the very muddy waters of just how you measure ERP - seemingly a very imprecise science. Also the far more interesting area of matching the antenna to the propagation medium (sometimes referred to as ionospheric matching). An example of this is the idea that a "useless" horizontal antenna - or the horizontal part of an L - can in some cases give an improvement on the pure vertical because of the way the signal is presented to the ionosphere. And this is another area where the unreliability of the technique makes it a taboo area for the commercials but a potential source of gold for us. Isn't radio fascinating?

I have built a standard based on this design and it performs very well. Schematic, PCB (Eagle format) and Gerber files are available on request. Shera's original PIC software runs fine on my board. Be careful with those brand-x GPS receivers though. The accuracy of the 1pps output can be as bad as several microseconds or even worse. The long term accuracy is probably good enough but we know nothing about how the jitter behaves. There are GPS receivers designed specifically for timing applications. The 1pps pulse from a Motorola Oncore UT+ doesn't jitter more than 30ns around the true second. Brooks Shera told me that my old Rockwell NavCore-V wasn't good enough (spec'd accuracy 1us) so I bought an UT+ instead. 73 Johan SM6LKM From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 23775 invoked from network); 4 Jan 2001 16:35:20 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by 10.226.25.101 with SMTP; 4 Jan 2001 16:35:20 -0000 Received: (qmail 85 invoked from network); 4 Jan 2001 16:38:37 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 4 Jan 2001 16:38:37 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14EDGn-0000Ko-00 for rsgb_lf_group-outgoing@blacksheep.org; Thu, 04 Jan 2001 16:29:41 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from d06lmsgate-2.uk.ibm.com ([195.212.29.2]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14EDGj-0000Ke-00 for rsgb_lf_group@blacksheep.org; Thu, 04 Jan 2001 16:29:37 +0000 Received: from d06relay01.portsmouth.uk.ibm.com (d06relay01.portsmouth.uk.ibm.com [9.166.84.147]) by d06lmsgate-2.uk.ibm.com (1.0.0) with ESMTP id QAA72100 for ; Thu, 4 Jan 2001 16:14:48 GMT Received: from usa.net (ss1.bld.socks.ibm.com [9.14.4.66]) by d06relay01.portsmouth.uk.ibm.com (8.8.8m3/NCO v4.95) with ESMTP id QAA64522 for ; Thu, 4 Jan 2001 16:28:49 GMT X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Message-ID: <3A54A4A3.3D7FDD64@usa.net> Date: Thu, 04 Jan 2001 17:28:19 +0100 From: "Alberto di Bene" Organization: Undisclosed X-Mailer: Mozilla 4.76 [en] (Win95; U) X-Accept-Language: en MIME-Version: 1.0 To: rsgb_lf_group@blacksheep.org Subject: Re: LF: Freq stability, cheap source of References: <65AECDF1F89AD411900400508BFC869F0D74E2@pdw-mail-1.dera.gov.uk> <003d01c0765e$2e2a9580$0a00a8c0@ThreeLakes.ca> Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 8bit Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Larry Kayser wrote: > Greetings All: > > There is a very cheap source of very high stability reference available to > everyone.

There was a German article published several years ago for a 10MHz frequency standard locked to TV line sync and this reappeared a few months later, slightly updated, in the UK Microwave Newsletter. It requires a TV receiver of some sort but only generating a low level video signal; the frequency standard incorporates its own sync separator. I butchered an old portable TV destined for the rubbish tip for its receiver board. Beware of local opt-outs (or whatever they are called) where local or regional TV stations transmit local information rather than that nationally. In that case, they usually go to a locally generated reference rather than the central high stability one. In the UK, BBC Television is Caesium or Rubidium locked nationally, but for local news etc experience shows phase / frequency shifts at certain times. However, I've always seen a few parts in 10^-9 short and long term stability. Another source of high accuracy transmissions is Longwave braodcasts - in the UK and France at least, the carriers are all generated locked to national standards. At Droitwich a Rubidium source is actually used as it has a lower phase noise than using a Caesium source directly, but it is compared in phase and corrected with a Cs source on a daily basis (to quote a BBC employee).

Please give some more details on this other problem. Which resolution have you set on your Windows PC ? Could you please take a snapshot of the Argo window with this problem evident ? You can do it by using the Argo capture facility.

To All from PA0SE
 
A simple system combining the flexibility of a VFO with the stability of a quartz crystal is a V FO + "Huff and Puff" frequency stabiliser. This device frequency-locks the VFO to the nearest one of a series of frequencies that increase in steps of for instance 32Hz and are derived from a crystal.
 
Take for instance a VFO in the 8MHz range and a stabiliser with 32Hz raster. When divided by 64 down to 136kHz the frequency steps become 0.5Hz. After manually tuning the VFO the frequency creeps towards the nearest raster point which is never more than 0.25Hz away and it stays there.
 
When a crystal at room temperature is not good enough a TCXO could be used.
 
The "Huff and Puff" system was designed by the late Klaas Spaargaren, PA0KSB and described in many articles in among others RadCom and Ham Radio. Also in my copy of the fifth edition of Pat Hawkers Amateur Radio Techniques and possibly in later editions as well.
Mike, G3XDV, publications manager of RSGB, can no doubt tell you more about this.
 
I use a "Huff and Puff" stabiliser on the VFO of my valved HF-band transmitter and it functions exactly as expected. I would certainly add one to the 8MHz VFO of my LF-band transmitter if I were to use QRSS. For normal CW the VFO in itself is stable enough.

Funny, the two extremes of the spectrum have the same problems of detection of signals below the noise. I was reading a couple of days ago about the experiments done by John K3PGP using a modulated laser light, aimed at the sky. He says that it was possible to receive the scattered light and to recover the modulation at 25 km distance... impressive.

Andy,
 
Thanks for the comments on frequency stability.  Much appreciated.
 
My personal situation is that I am arranging for my TS-850 (built with a 4 channel DDS lineup) to have a better timebase than catered for by Mr Kenwood.  I have implanted a 0.5 ppm TCXO with voltage fine tuning, and have the tuning voltage on a rear panel phono socket, so an external resistor can adjust fine tuning (easy resetting, using WWV or equivalent, I also have the 800 Hz precision side tone at the rear panel, an XY scope display can show Rx audio against 800 Hz sidetone.  I have a 30 Hz DSP filter in the Rx audio feed, with 800 Hz centre frequency.  The TS-850 tunes in 1 Hz steps).
 
I now have a 40 MHz OCXO with voltage fine tuning, and that is under test, and appears to have a stability of a bit better than 0.1 ppm.  The TS-850 also has a rear panel 10 kHz clock from the DDS master, intended for locking an external Kenwood DSP box (which I do not have) but can obviously be used for a PLL to a better external osc.  So the TCXO control can alternatively go to the PLL phase detector rather than a fixed resistor.
 
I am also having a sniff at locking to off-air TV which has Rubidium accuracy in the pulse TIMING.  For some time I was going sideways with trying to detect the 15.625 kHz sideband FREQUENCY of a TV emission but ended up proving it has significant phase shift over the modulation cycle so is "too dirty" to consider as a master phase lock source.
 
I use my TS-850 for on-frequency LF Tx, as well as Rx, and obviously the tuning accuracy applies to higher frequencies as well.
 
But as yet I have not run any QRSS or BPSK software ...
 
73, Bob

Now that you have specified that returning the slider at the start position didn't restore the exact contrast as it were there, I specifically checked for this, and, sure enough, it happened on my PC too.. The fix has been trivial, just make the initial value of a variable congruent with the initial position of the slider. It was in the beginning, but then I changed one without changing the other... TNX you both for your report, and check the Web site for the new version in a couple of days. 73 Alberto I2PHD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 25368 invoked from network); 3 Jan 2001 18:16:26 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by extortion.plus.net with SMTP; 3 Jan 2001 18:16:26 -0000 Received: (qmail 27346 invoked from network); 3 Jan 2001 18:19:02 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 3 Jan 2001 18:19:02 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14DsP0-0003A9-00 for rsgb_lf_group-outgoing@blacksheep.org; Wed, 03 Jan 2001 18:12:46 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from d12lmsgate-3.de.ibm.com ([195.212.91.201]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14DsOz-0003A3-00 for rsgb_lf_group@blacksheep.org; Wed, 03 Jan 2001 18:12:45 +0000 Received: from d12relay02.de.ibm.com (d12relay02.de.ibm.com [9.165.215.23]) by d12lmsgate-3.de.ibm.com (1.0.0) with ESMTP id TAA198934 for ; Wed, 3 Jan 2001 19:12:06 +0100 Received: from usa.net (ss5.bld.socks.ibm.com [9.14.4.70]) by d12relay02.de.ibm.com (8.8.8m3/NCO v4.95) with ESMTP id TAA128190 for ; Wed, 3 Jan 2001 19:12:04 +0100 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Message-ID: <3A536B55.F0FEE103@usa.net> Date: Wed, 03 Jan 2001 19:11:33 +0100 From: "Alberto di Bene" Organization: Undisclosed X-Mailer: Mozilla 4.76 [en] (Win95; U) X-Accept-Language: en MIME-Version: 1.0 To: rsgb_lf_group@blacksheep.org Subject: Re: LF: Gyrators References: <20215890.978543215896.JavaMail.imail@bernie.excite.com> Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 8bit Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: john sexton wrote: > Hi Alberto > Stokes original article was re-printed in the old LF Experimenters Source > Book, together with another explaining the theory. > I built the original circuit.

I built the original circuit. It is very simple and lacks most of the features required in a decent receiver. It definitely works, but I found it did tend to break into oscillation, possibly because of problems with the screening of the pot leads (although I am pretty certain I screened them) as he mentions in the revised article. I also found the 4136 very sensitive to over-voltage and eventually used a couple of 9V batteries. At 12V problems arise. I didn't find the tuning that sharp, although I used good polystyrene caps in the critical places, but that is hardly surprising when you look at the circuit. As a replacement for a big inductor it's a great idea. My son used it for a GCSE project for a MSF computer clock and won a prize. It is perhaps most useful for the "below 9kHz" boys, but only for receive of course. I would be interested in your findings. 73 John, G4CNN _______________________________________________________ Send a cool gift with your E-Card http://www.bluemountain.com/giftcenter/ From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 13044 invoked from network); 3 Jan 2001 17:20:13 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by extortion.plus.net with SMTP; 3 Jan 2001 17:20:13 -0000 Received: (qmail 12003 invoked from network); 3 Jan 2001 17:22:49 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 3 Jan 2001 17:22:49 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14DrV6-0002s1-00 for rsgb_lf_group-outgoing@blacksheep.org; Wed, 03 Jan 2001 17:15:00 +0000 Received: from mail4.svr.pol.co.uk ([195.92.193.211]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14DrV4-0002rw-00 for rsgb_lf_group@blacksheep.org; Wed, 03 Jan 2001 17:14:58 +0000 Received: from modem-52.brandir.dialup.pol.co.uk ([62.136.141.180] helo=lvm) by mail4.svr.pol.co.uk with smtp (Exim 3.13 #0) id 14DrUq-0006Dp-00 for rsgb_lf_group@blacksheep.org; Wed, 03 Jan 2001 17:14:44 +0000 Message-ID: <000101c075a9$276001a0$b48d883e@lvm> From: "LAWRENCE MAYHEAD" To: "rsgb lf group" Subject: LF: Re.

The problem is that if I move the slider away from the start position either way left or right the contrast changes as expected BUT when I return the slider to exactly the same place the contrast is different! in fact I cannot return to the original with any setting of the slider! It is strange and may be my computer,although I did reload the progran just to be sure and the effect is still there. If no one else has this problem please ignore it and I will try to sort it out here, I dont want you to hold things up for what may be a mistake of mine.Many thanks Laurie.

They don't need to use ancient stop start signalling in most cases as there are plenty of better ways of achieving bit sync. A few are also possibly commercial private navigation systems. You could try direction finding and co-ordinate with someone a long way off to get some sort of triangulation. DF is quite reliable with loops at these frequencies provided you stay away from nearby conductive structures. If you could decipher the message content you would probably have to be shot !

My loop, which is matched via a capacitor divider network as described on my web site, has a usable bandwidth of around 300Hz before retuning it is necessary. But it is not effected by rain or movement (apart from in heavy winds when the SWR jumps somewhat), the only environmental change is between hot and cold weather when the value of the tuning caps changes - on a cold frosty morning it is some 300Hz lower in frequency which rapidly moves the other way when the sun starts to shine on the matching box! I also spoke to Mike Underhill after his talk and he is certainly interested with the work we are doing with loops on lf. Results some of us have achieved seem to indicate that conventional theory is too pessimistic and I look forward to seeing his report in writing. It seems Mike is not available via email.

What the hell do all the other 48 stations do? I can successfully display their data stream in binary format, i.e. make mark frequency cause display of a binary 1 and space frequency cause display of a binary 0 (or vice versa). Thereby I can retrieve their Baudrate. But no known coding scheeme (ARQ, FEC, ASCII etc) causes a readable display. I am not dreaming of de-chiphering the chiphered message contents! All I want is to let the decoder display a stream of ASCII characters in order to eventually see some station call signs or something else which can point me to the origin of those signals.

If the error checking routine measures the amount of error, for example with ET1 in Coherent how many of the bits are in error, then outputs an error symbol if more than a particular threshold is reached, there is less likelihood of noise generating random messages. The error detection method in Amtor Broadcast mode (no handshaking) does this. An incorrectly received character prints out as an error symbol rather than a, probably more serious, wrong character. Another analogy to the light description, is to listen to noise than has been bandpass filtered to just a few Hz wide - it sounds remarkably like a tone modulated at the rate of the bandwidth. The WJ8711 HF receiver has a 56Hz wide filter included - noise sounds so remarkably like a weak RTTY signal that we've tried to decode it before now !!

It was easy to achieve TX stability within a few Hz using the VFO, provided the temperature didn't vary too wildly; the main requirement is just that your signal frequency does not drift into someone else's, or a Loran line, carrier, etc. so a few Hz is adequate. It is easy to keep an eye on the spectrogram display to make sure this is not happening, and make manual adjustments if neccessary - of course, much finer tuning adjustment is required compared to normal CW. The exact frequency is not important, because it is easy to monitor 100Hz or more of bandwidth at the receive end. Having said that, some truly dreadful VFO's have appeared on the air from time to time! The mixer-VXO circuits seem to be somewhat better than VFO's in terms of stability and are perfectly adequate for most things. On receive, stability is even less important - the frequency has to drift many Hz per minute to make any difference from the sensitivity viewpoint, and this isn't hard to achieve. Drift just results in a bit of a slant on the spectrogram display. I once tried an old HRO on 136kHz, and once warmed up, stability wasn't too bad for QRSS. Selectivity left a lot to be desired, though, so I wouldn't recommend it. Provided you don't mind checking and adjusting the TX and RX frequencies every few minutes, QRSS operating with 3s per dot can be done with crude equipment. Longer dot lengths, or long-term monitoring, requires something a bit better, but any synthesised or crystal controlled equipment should be adequate. My experience of BPSK is currently very limited - but using a locally generated signal with reasonable SNR, VE2IQ's "Coherent" software seems to cope with a 1Hz frequency error without much trouble, but 2Hz is too great, when using the MS100, 10 bit-per- second data rate. As Andy points out, it isn't hard to get better stability than this. The 1 in 10e-7 level of stability seems to be more or less standard for the ovened references that are getting cheaper in surplus test gear available at rallies and so on. This should be OK for 1 bit-per-second BPSK speeds at LF - the main problems seem to be knowing what frequency to tune to in the first place, and the fact that the HF gear that normally gets pressed into service wasn't really conceived with such narrow tuning resolution in mind. And loops- A receiving loop has it's own intrinsic signal to noise ratio that, for a small loop, depends on the unloaded Q. Noise in the loop arises from the thermal noise produced by the resistive losses. The higher the unloaded Q, the greater the available signal power, while the noise power stays the same. However, the overall system signal to noise ratio depends very much on the type of circuit the loop is connected to - the optimum matching for a particular receiver input may or may not significantly alter the Q. The FET preamps used tend to give their lowest noise figures when fed from a high source impedance, and have a high input impedance themselves, so don't significantly reduce the Q. This is not generally true of other input circuits. A low impedance input circuit will almost certainly acheive it's best SNR using matching where the loaded Q is significantly lower than the unloaded Q. The loaded Q therefore does not directly control the signal to noise ratio. It is not easy to say what will give the best results, because receiver input circuits vary, and their input impedance is likely to be anything except 50ohms, especially at LF. But usually obtaining the highest possible SNR is not that important, because it is fairly easy to make the antenna/preamp noise less than the external noise, of which there is plenty at LF, with reasonably sized loops. G3LNP's design deliberately degrades the Q to give a wider bandwidth, and eliminate the need for remote tuning. Another reason why you might not want the highest possible Q is that a high Q loop is more easily de-tuned, for example by rain or movement.

Very high power into a small antenna will create additional problems (as extreme voltage) that can be avoided with big antennas But we hams live in a different world with our 1 Watt ERP restriction, apart from legal limitations (building restrictions) a 30 or 40m tower will be more expensive than a 2kW PA.

Unfortunately I have not yet managed to find this talk published anywhere. 2) Surely using a coupling loop is not a matter of matching the loop impedance to 50 ohms, but rather providing input coupling which does not unduly dampen the Q of the primary loop (which should be tuned with a capacitor). While this is a popular method it does not provide maximum signal to the receiver and should not be coupled by a long line. In the case of the G3LNP loop, the measured Q was 65, and the inductance (calculated using G4GFQ's RJELOOP3 program) is 6.3 mH, so the dynamic resistance of the tuned loop is 84 ohms. Using a Z-match to couple to the receiver would halve the Q and would require a 29 turn secondary, obviously excessive. The loss of signal due to using a single turn coupling loop is not adequately made up by the receiver in my experience, however there may be some bright ideas out there to learn from.

'Slow CW' has tended to mean a few words per minute as used for Morse practice. We used to say 'extremely slow CW' which was rather long. The QRP people use QRPP for extremely low power, so QRSS was suggested to make the term shorter. More recently, it has come to mean linear Morse rather than the split frequency form (such as DFCW), and the term VCW - visual CW - was suggested by ON7YD to cover all types of Morse decoded by eye.

Actually, I think you'd find this effect wouldn't show up if you were to use plain ASCII. If Bill de Carle and/or Andy come along, they may wish to amplify upon or correct my train of thought here, as I'm working from a very elementary understanding of error correction techniques, but I believe the effect is an artifact of error-tolerant coding methods. When one defines an error correction protocol, the decoder is required to make a decision about whether an error exists, based on the state of specific bits or combinations of bits transmitted along with the payload data. If an error is detected, a best-guess estimate is made of what the original character might have been, given the pattern of corruption perceived. A good correction algorithm will make educated guesses, which in turn will be based in one fashion or another on probability. Hence, with most any error correction scheme (if the output is not deliberately muted at some threshold) when the input trends toward truly random noise, the decoder will keep guessing at what output would "make sense" for the nearest combination of legitimate bits. Since what "makes sense" to the algorithm is based on probabilities defined by the programmer, the decoder will trend toward certain symbols more than others. I'm sure there are better mathematical terms for this, but the essence is: if the input to COHERENT is truly random, the output is a "weighted randomness." It's just as truly random as the input. All legal symbols will eventually appear, and there will be no real order to them. However, the chance of any one character appearing at a given instant is no longer a simple 1-chance-in-x-to-the-power-of-y probability. It's more like the randomness of energy from an incandescent lamp. Energy levels of individual photons in the flux are definitely random, yet the spectral curve peaks at some color temperature around which most of the energy will be found. A suitable analogy for the Grab feature might be an optical filter that happens to have the same response curve as the incandescent light source being shone through it. The more such filters one stacks in front of the light (that is, the greater Grab depth), the narrower the range of wavelengths which will be visible to the eye. Ultimately, the light would appear nearly monochromatic, just as the decoder would clearly begin to output one character more often than all others; but it would never truly become--pardon the expression--coherent. 73, John KD4IDY From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 5119 invoked from network); 2 Jan 2001 17:41:48 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by extortion.plus.net with SMTP; 2 Jan 2001 17:41:48 -0000 Received: (qmail 11248 invoked from network); 2 Jan 2001 17:44:23 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 2 Jan 2001 17:44:23 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14DVIj-00050V-00 for rsgb_lf_group-outgoing@blacksheep.org; Tue, 02 Jan 2001 17:32:45 +0000 Received: from hestia.herts.ac.uk ([147.197.200.9]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14DVIf-00050Q-00 for rsgb_lf_group@blacksheep.org; Tue, 02 Jan 2001 17:32:42 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from [147.197.200.44] (helo=gemini) by hestia.herts.ac.uk with esmtp (Exim 3.16 #4) id 14DVFl-0006eQ-00 for rsgb_lf_group@blacksheep.org; Tue, 02 Jan 2001 17:29:41 +0000 Message-ID: <2107.200101021732@gemini> From: "James Moritz" Organization: University of Hertfordshire To: rsgb_lf_group@blacksheep.org Date: Tue, 2 Jan 2001 17:35:55 +0000 MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII; format=flowed Content-Transfer-Encoding: 8bit Subject: LF: Happy New Year - Transatlantic X-Mailer: Pegasus Mail for Win32 (v3.11) Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Dear LF Group, A happy new year to all - I have been without E-mail facilities over Christmas, so have just spent a couple of hours reading through the 260 or so e-mails that had accumulated - mostly from the LF group! It might take a while to digest all of it. I didn't have a lot of time for radio things over the holiday, but like several others I was able to copy VE1ZZ most nights - best reception was during the early mornings of 25th and 26th of December. The limiting factor on signal quality at my QTH was QRN, which perversely was much higher than it had been in the run- up to Christmas. I was quite suprised that the signal strength could vary as quickly as it does, sometimes 5 minutes is all the difference between good copy and unreadable signals. I look forward to the tests of the 12th/13th, and will certainly be taking part. As far as frequencies go, the best bet as far as I can see for the EU side is using the bottom band edge as we did effectively in the autumn - provided we avoid the frequencies used by SXV, this should avoid interference to other users in Europe, and is the favoured part of the band for Canadian/USA listeners. The 136.5kHz frequency in use by VE1ZZ is probably OK, provided nobody decides to fire up on CW; but usually activity is low late at night. So I plan to use either 135.715kHz, or 135.916kHz depending on what SXV is doing, or unless somebody else desperately wants to use these frequencies. Something else that would be worth clearing up is what dot lengths will be in use - VE1ZZ has made use of rather short dots, which works OK for his signal . But since he appears to have a much higher ERP available than any European station, it would probably be best if everyone else stuck to 3s dots. In any case, it would help to know in advance, so that software settings can be optimised. I also got my BPSK receiving gear going over Christmas- I now have a W&G SPM19 level meter with homebrew external preselector and demodulator, feeding one of G4JNT's PIC interfaces to VE2IQ's "Coherent" software. The SPM19 has an ovened reference with 10e-7 stability, and 1Hz tuning steps. The demodulator uses the reference output to synthesise the BFO frequency, maintaining the overall stability, which should therefore be more than adequate. I have not yet received any off-air signals, but loop-back tests with a signal generator and BPSK modulator worked fine; I am now working on the transmitter - I just hope that everybody does not lose interest before I get the whole thing finished! I am a bit sceptical about the "Grab" feature of Coherent - the longer the grab length, the less random the output data seems to become, even with just noise being fed into the demodulator input. I saw quite a few unusual modes on 136kHz; Andy's SMT-hell, what I presume was PSK31from DK8KW and friends, and something which seemed to be the key-clicks of a CW signal, without the rest of the signal, when looking at 136.5kHz. I worked G3KMP for the first time on 136kHz - Colin expressed an interest in getting active soon on 73kHz, and being located in Hastings, he should be easily within range of a number of people; as before, I intend to be active on 73kHz on Friday evenings, if anyone else wants to try out their new NoVs.

During the holiday I converted the datafiles I received from the 'CFH recordig night' of 18 december into graphs. These can be found at : http://www.qsl.net/on7yd/t181200.htm During lunch break I had a look at the message from the reflector in this last period, very interesting : - VE1ZZ has been copied all over Europe, so the fact that I could copy him on several nights over the holidays is 'yesterdays news'. - Comments of growing interest of QRSS in the US and BPSK in EU were made. Regarding BPSK I'd like to comment that this is without any doubt a very interesting mode. But my observations with any new mode is that I will only become widespread if the 'treshold' is low enough. Remind that also QRSS was a operated only by very few of us until appropriate software, easy to use and to install, became available. Since then several new modes has been introduced (PSK, DFCW, BPSK) but none of them has become as popular as QRSS, simply because for QRSS you just have to install the software (running under windows), make connections to the TX/RX and off you go ... So far all other modes required some more or less complicated 'hardware' changes to the transmitter, as a result the 'audience' is very small. I believe that the only way to get over this 'hardware burden' and make these new modes more popular is either to search for a 100% software solution (what is almost impossible) or to provide a homebrew project that is simple and not too expensive to make (and stay away from exotic components). I remind that in the early days of 136kHz most of us had trouble to put a solid signal in the air, fooling arround with all kind of PA's with mostly just a few (tens) Watt output. Since some decent, cheap and rather foolproof PA designs (ie those of G3YXM and G0MRF) became available almost everybody can put several 100 Watt in the air without too much trouble. - Certain misunderstandings about the relation between antenna efficiency, antenna directivity, transmitter power and ERP survived the last milenium. The attemps to make us believe that 1 Watt ERP with a big antenna is more than 1 Watt ERP with a small antenna continue ...

Unless you can erect a loop with a huge area (100s of m^2 at these frequencies) you will always do better with an E field antenna than an H loop. Radiation resistance / efficeincy is proportional to the fourth power of loop dimensions (square of loop area) What do you mean by small - my garden is just 14m long x 6 wide and have a 7m high tee antenna with a radiation efficiency around -36dB and feed impedance 100 - 130 ohms - although being on heavy clay of good conductivity this is rather better than may otherwise be achieved. On a receiving loop , why is there such a fuss about preamps ? A tuned 1m square loop with several turns of wire, coupled with one turn (or any other suitable matching network) to a 50 ohm input provides more than enough signal for most receivers except perhaps the very deafest operating outside their specified frequency range.

Laurie I am scared of qrm from CFH at Jack's house. So I prefer to be listening at 135.7 but wud entertain testing at 135.9 to see if the Greek station is causing trouble All day yesterday and today 128.9 and DCF39 were coming in .Could hear both in earphones. They varied between S-1 and S-3 during daylight. Yesterday at 1930z and today at 2030 128.9 was S-5 good enough for reception of G0MRF This morning at 0630Z both 128.9 and DCF39 were S-7. S-7 should indicate conditions adequate for reception of 500 milliwatt ERP G station During Jan 12 and 13 tests I recommend testing start at 2000. Eu transmits following Jack's periods for 20 minutes . I recommend we continue until 0730 on both friday/sat nite and sat/sunday night. Eu tx freq should be 135.7 to 135.8 . I will have email available. I might call for change of freq to 135.9 if the Greek stn is too strong and if CFH is no problem. Over the next week or 10 days I hope we can run more tests with you in Eu transmitting and me listening here in Sydney to help determine my best freq for listening 73 all de John VE1ZJ From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 10336 invoked from network); 1 Jan 2001 23:48:23 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by extortion.plus.net with SMTP; 1 Jan 2001 23:48:23 -0000 Received: (qmail 28999 invoked from network); 1 Jan 2001 23:50:56 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 1 Jan 2001 23:50:56 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14DEdg-0000a8-00 for rsgb_lf_group-outgoing@blacksheep.org; Mon, 01 Jan 2001 23:45:16 +0000 Received: from email.cwcom.net ([195.44.0.152] helo=cwcom.net) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14DEdf-0000a3-00 for rsgb_lf_group@blacksheep.org; Mon, 01 Jan 2001 23:45:15 +0000 Received: from computer ([195.44.201.108]) by cwcom.net with Microsoft SMTPSVC(5.5.1877.537.53); Mon, 1 Jan 2001 23:45:05 +0000 Message-ID: <001901c0744d$17d4cde0$6cc92cc3@computer> From: "Martin M5CIX" To: rsgb_lf_group@blacksheep.org References: <000201c0742f$71542a00$348f883e@lvm> <3A50F301.D5DF243B@alg.demon.co.uk> Subject: LF: Loop Antennas for RX and TX Date: Mon, 1 Jan 2001 23:46:37 -0000 Organization: M5CIX / G8CIX MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.50.4522.1200 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Loop Antennas 1) Does anyone have any pointers to or formula for a loop aerial for transmitting on 136?.

One reason might be that John VE1ZJ - who is best placed to determine his preferred receive frequency - has already stated "I would prefer that anyone trying to come . . . to North America would use 135.7 to 135.8". John has also stated that he doesn't believe that the Greek station will stop reception below 135.8 kHz.

We will try this year Franks' newly built e-field probe that appears to exhibit a fairly remarkable (+32dBm) compression point, and may thus go a long way to avoid the Loran signal interferences we experienced last year. We have established in the past that 1800h-2400h local time (2300-0500 Zulu) is about the best time period for us to receive European Long-wave broadcast (such as France-Inter). Hence we will be listening Saturday 13 January at 2300Z until Sunday 14 at 0500Z and again from Sunday 14 at 2300Z until Monday 15 January 0500Z. Please let us know who will be transmitting what (QRSS ?) and on what frequencies. Last year, the British amateurs who agreed to transmit that week end managed to coordinate their transmitting frequencies so that these would all be clustered and may be observed on only _one_ Spectran screen. Spacing of 10Hz between stations is fine. Also silent periods of 30 seconds between ID transmissions will allow us to better identify for sure whether we are seeing a real weak amateur signal, or simply hallucinating because we have been staring at those screens for too long :-) We will have Internet access at Nags Head, and like last year, will be able to call you over the telephone if successful. 73 Andre' N4ICK From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 11838 invoked from network); 1 Jan 2001 19:18:55 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by extortion.plus.net with SMTP; 1 Jan 2001 19:18:55 -0000 Received: (qmail 23029 invoked from network); 1 Jan 2001 19:21:29 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 1 Jan 2001 19:21:29 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14DAPb-0007wg-00 for rsgb_lf_group-outgoing@blacksheep.org; Mon, 01 Jan 2001 19:14:27 +0000 Received: from hs-img-4.compuserve.com ([149.174.177.149] helo=sphmgaad.compuserve.com) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14DAPa-0007wb-00 for rsgb_lf_group@blacksheep.org; Mon, 01 Jan 2001 19:14:26 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: (from mailgate@localhost) by sphmgaad.compuserve.com (8.9.3/8.9.3/SUN-1.9) id OAA09071 for rsgb_lf_group@blacksheep.org; Mon, 1 Jan 2001 14:14:17 -0500 (EST) Date: Mon, 1 Jan 2001 14:13:34 -0500 From: "'Geri' Kinzel, DK8KW" Subject: LF: Re: LF Test freqs To: rsgb_lf_group@blacksheep.org Message-ID: <200101011413_MC2-C04D-E0C4@compuserve.com> MIME-Version: 1.0 Content-Transfer-Encoding: 8bit Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Disposition: inline Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Dave, G3YMC wrote: > To date we have had CW, QRSS, >BPSK and associated data modes, and now we are getting slow voice which requires >its own space. < ... just a few words regarding slow-voice: I don't think that this mode currently requires its own space. Since it is an experimental mode which requires a rig with SSB capability (like most of the digital modes, too), I suggest that we run tests in the area between 137.300 and 137.600 kHz, collisions with PSK31 or other modes will surely be avoided as we do not have really much of those special modes currently. I already developed an idea how I filter out the DCF39-noise. I don't really know *what* had happened on Saturday night, but at least outside of the U.K. I think it did not get big attention. I saw some people calling QRSS to reach VE1ZJ on 136.500 plus/minus acouple of kHz, but I personally had no poblems with these transmissions.

The 136kHz band is slightly different from other hf bands in so far that it is rather narrow, and there is a far greater conflict between the various modes of transmission which are all fighting for space. To date we have had CW, QRSS, BPSK and associated data modes, and now we are getting slow voice which requires its own space. It is therefore always going to be difficult to provide enough space for all users without mutual interference. The band plan which has been worked out (admittedly a couple of years ago when some of the modes were not active) was produced in good faith, and like the band plans on the higher bands it makes life easier for us all if they are followed. Up to recently most of the slow CW and data communication has indeed been confined to their allocated parts of the band, and this has worked well, with very little mutual interference between normal CW and the data modes. However a conflict in situations both here and in Canada/USA threatens to upset this relationship. There is an analogy between unwanted mixing of SSB and CW on hf, whereas an SSB QSO can be conducted with CW interference in the background, whereas the SSB signal gives significant interference problems to the CW operator. In a similar way, users of slow CW and other spectrogram modes have so much more selectivity in their digital processors that they are not usually effected by signals 10s of Hz away unless these are very strong local ones. The normal CW op, using normal receive filters assisted with audio filtering, can find such adjacent signals disasterous. And the inability to identify in normal CW and respond when transmitting such digital modes seems rather unsatisfactory. I would strongly urge all operation on slow CW and other data modes to continue to be made in the recognised parts of the band, and leave 136.0-137.4 for normal CW. There are indeed times when this part of the band may be quiet and unused, but at busy times (eg Sunday mornings) it is barely adequate. If it is possible to get Jack to move his test transmissions out of this section it would be appreciated - although Jack's signal is unlikely to affect a normal CW operator, the unintentional QRM caused by an operator who does not know he is there could be a problem. Hopefully there will not be a repeat of the events of Saturday night. 73s Dave G3YMC (on the analogue side of the digital divide...) sergeantd@compuserve.com dsergeant@iee.org http://ourworld.compuserve.com/homepages/sergeantd From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 22035 invoked from network); 1 Jan 2001 16:16:16 -0000 Received: from unknown (HELO warrior-inbound.servers.plus.net) (212.159.14.227) by 10.226.25.101 with SMTP; 1 Jan 2001 16:16:16 -0000 Received: (qmail 17599 invoked from network); 1 Jan 2001 16:19:31 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 1 Jan 2001 16:19:31 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14D7ah-0007CP-00 for rsgb_lf_group-outgoing@blacksheep.org; Mon, 01 Jan 2001 16:13:43 +0000 Received: from cmailg2.svr.pol.co.uk ([195.92.195.172]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14D7ag-0007CK-00 for rsgb_lf_group@blacksheep.org; Mon, 01 Jan 2001 16:13:42 +0000 Received: from modem-77.erythromycin.dialup.pol.co.uk ([62.136.93.77] helo=default) by cmailg2.svr.pol.co.uk with smtp (Exim 3.13 #0) id 14D7aX-0008WH-00 for rsgb_lf_group@blacksheep.org; Mon, 01 Jan 2001 16:13:33 +0000 Message-ID: <000001c0740d$0b8471c0$4d5d883e@default> From: "MAL HAMILTON" To: "rsgb" Subject: LF: sub bands Date: Mon, 1 Jan 2001 12:47:40 -0000 MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 4.72.3110.5 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: I think the sub band arrangement for very slow cw would be preferable to a free for all. Split frequency operation as well. Arrange for EU stations to transmit below 136 khz and the dx above 137.5 or reverse (EU tx above 137.5 and dx tx 136 and below) What ever arrangement suits most, as long as we all know what procedure is in use. The rest of the band to be used by the majority for normal cw. There could also be a data mode sub band say 137.3 - 137.5 or there abouts. With the use of so many high power FET rigs on the band the keying characteristics need to be addressed to avoid clicks and sideband spurii. Instead of keying the exciter into the PA, which seems to be the norm, the PA supply voltage needs to be keyed and leave the drive on. Another important consideration is a good narrow cw filter in the receiver and preferably dsp. Some that complain about qrm is their own fault because of inadequate rx selectivity filtering or a poor receiver. At busy periods we all have to squeeze in and the necessary precautions must be taken. A lot of LFers already know this but its surprising how many do not or rely on luck.

There is a worrying trend to use 136.5kHz for transatlantic transmissions. I understand that VE1ZZ is crystal controlled, so he can be forgiven. However, I have heard both QRSS and conventional CW transmissions from G stations on this frequency aiming to be heard in VE. Two problems are raised here: one is mentioned by Steve above, and the other is that co-channel operation is extremely inefficient for this type of marginal contact. It was not long ago that sub-bands were proposed for Eu-NA (low end of band) and NA-Eu (high end of band). I have the details of this on my web site and requests for comments produced no result so I assume they are still accepted. Is there now (1) a wish for a free-for-all, or (2) a wish for new sub-bands? I, for one, am very confused. Where should I transmit and receive now?

I checked it out this morning and its true I was set up for DFCW, a mode I use quite often,but since I was using Daves Decca transmitter there is no provision for frequency shift so only the keying signal was working!!! Probably due to the fact that I kept slipping away from our New Year party trying not to let my wife see that I had gone,so didnt really check things properly Hi (could have been the wine though! ).One intresting thing to come out of it is that I saw Jacks signal for 4 hours at 30min. intervals. At 2230 it was just visible R T but by 0230 it was a thumping OOO and probably went on rising but I just had to go to bed.So I am sorry John there was no way I could respond to your 0600 sked.But I will try another time. 73s to all From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 2663 invoked from network); 1 Jan 2001 07:22:28 -0000 Received: from unknown (HELO murphys-inbound.servers.plus.net) (212.159.14.225) by excalibur.plus.net with SMTP; 1 Jan 2001 07:22:28 -0000 Received: (qmail 11232 invoked from network); 1 Jan 2001 07:17:13 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 1 Jan 2001 07:17:13 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #1) id 14Cz42-0004zK-00 for rsgb_lf_group-outgoing@blacksheep.org; Mon, 01 Jan 2001 07:07:26 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from anchor-post-33.mail.demon.net ([194.217.242.91]) by post.thorcom.com with esmtp (Exim 3.16 #1) id 14Cz41-0004zF-00 for rsgb_lf_group@blacksheep.org; Mon, 01 Jan 2001 07:07:25 +0000 Received: from alg.demon.co.uk ([194.222.171.80]) by anchor-post-33.mail.demon.net with esmtp (Exim 2.12 #1) id 14Cz3s-000Fny-0X for rsgb_lf_group@blacksheep.org; Mon, 1 Jan 2001 07:07:16 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Message-ID: <3A502BCA.8058A85F@alg.demon.co.uk> Date: Mon, 01 Jan 2001 07:03:38 +0000 From: "Steve Rawlings" X-Mailer: Mozilla 4.6 [en-gb]C-CCK-MCD NetscapeOnline.co.uk (Win98; I) X-Accept-Language: en-GB,en MIME-Version: 1.0 To: rsgb_lf_group@blacksheep.org Subject: Re: LF: Re: Apology References: <2000123112535868199@zetnet.co.uk> Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 8bit Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Hi Peter Apology accepted, OM.

The problem is that he that when he sends QRSS he use the same length for both dits and dah's. As I am writing this (0226z) he again has just sent his call twice in QRSS and once at normal speed. The QRSS signal was as previously stated but the normal CW was OK. To someone who does not hear/read the faster CW his call at QRSS either becomes all dit's or all dah's.

Andre' N4ICK **************************************** Friday December 29 01:15 PM EST Passing of a wireless pioneer By David Coursey, ZDNet News Remembering a forgotten wireless pioneer. "The man who brought the world such indispensable wireless communications concepts and devices as the walkie-talkie, pager, and cordless telephone has died." That's the lead sentence of an email I just received from a ham radio news service I subscribe to. The story is so interesting and the accomplishment so great that I'd like to share it with you. First, though, I'll need to shut off the cordless phone, put the pager in silent mode, and turn down the volume on the walkie-talkie I use in my volunteer work. It is startling to realize how much I owe to the inventions of a guy I didn't even know about. And now he's dead. His name was Al Gross. His ham radio call sign was W8PAL, and he died four days before Christmas at his home in Sun City, Ariz. Here's the rest of the email: "Gross obtained his amateur radio license in 1934 at the age of 16. His early interest in amateur radio helped set his career choice while he was still a teenager. "Gross pioneered the development of devices that operated in the relatively unexplored VHF and UHF spectrum above 100MHz. His first invention was a portable hand-held radio transmitter-receiver. "Developed in 1938 while he was still in high school in Cleveland, he christened it the 'walkie-talkie.' The device caught the attention of the US Office of Strategic Services -- the forerunner of the Central Intelligence Agency. The OSS recruited Gross, and this led to the invention of a two-way air-to-ground communications syste m used by the military behind enemy lines during the World War II. The system allowed OSS agents to communicate with high-flying aircraft. "After World War II, Gross set up Gross Electronics Inc to design and build various communications products, some of them under government contracts. He also launched Citizens Radio Corporation to design, develop and manufacture personal wireless transceivers. "Cartoonist Chester Gould asked if he could use Gross' concept of a miniaturized two-way radio in his Dick Tracy comic strip. The result was the Dick Tracy two-way wrist radio. "During the 1950s and 1960s, Gross secured several patents for various portable and cordless telephone devices. In September 1958, Gross Electronics received FCC type approval for mobile and handheld transceivers for use on the new Class D 27-MHz Citizens Band. "'If you have a cordless telephone or a cellular telephone or a walkie talkie or beeper, you've got one of my patents,'Gross once said. He added! ! that if his patents on those te chnologies hadn't run out in 1971, he'd have been a millionaire several times over. "Over the years, Gross worked as a communications specialist for several large companies. Since 1990, he had worked as a senior engineer for Orbital Sciences Corporation (NYSE:ORB - news) and was still on the payroll there when he died. "Gross received numerous awards and honors during his distinguished career, including the 1992 Fred B. Link Award from the Radio Club of America, the 1997 Marconi Memorial Gold Medal of Achievement from the Veteran Wireless Operators Association, and the 1999 Edwin Howard Armstrong Achievement Award from the Institute of Electrical and Electronics Engineers. In 1998, he received Eta Kappa Nu's Vladimir Karapetoff Eminent Members' Award in recognition of his pioneering contributions to the engineering of personal wireless communications. "Earlier this year, he won the Lemelson-MIT Lifetime Achie vement Award for invention and innovation and for playing a major role in the wireless personal communications field." As his IEEE biography put it: "It is clear that Mr. Gross was a true pioneer and helped lead the way to today's wireless personal communications revolution." Gross was, of course, only one of many communications pioneers. Yet his accomplishments are all around us. Someday our children will be startled to learn of the deaths of some Internet pioneer or maybe someone from Xerox PARC--an Al Gross of our age.

-----Hi.  I am nearing the end of writing my column in the local amateur radio journal and I am a bit thin on
frequency stability guidelines for working QRSS and BPSK on LF.  Nobody in ZL has yet got going on these modes but I want to publish info that does not give any locals a bum steer as to what to do to get into digital modes on LF.
 
Could you fire me some summary comments on what frequency stability should be achieved by transmitters and receivers to join the game, for respective modes?
Cheers,
Bob ZL2CA
 
Hi Bob -
I've copied this reply to the LF Group as well for general information...........
 
QRSS ( 'SLOWCW', why invent meaningless Q codes for the sake of it) as usually practiced now, calls for a resolution bandwidth of 0.3Hz or wider in order to see the 3s dot period.  But as this mode is always viewed on a spectrogram display generated from an FFT, we are actually seeing a large chunk of spectrum, typically many 10s to 100Hz simultaneously and a drift of a 1Hz or so probably won't be noticed.  Thus the frequency stability needed for this mode can be a very poor 10 parts per million - which even the cheapest and nastiest crystal can manage - hence one of the popularities of the mode.  A 10s dot peroiod is occasionally used calling for a 0.1Hz bin size or less but still a few ppm accuracy will suffice.
 
For BPSK, a frequency stability of the order of a tenth the bit rate is needed,a lthough a figure of better than this speeds initial lock up.  Once locked, the frequency can drift outside this range, and manual assistance ina chieving initial lock by 'nudging' the tuning process can allow worse initial frequency setting accuracy.    So for the 100ms (10B/s) rate we normally use, 1Hz stability is ideally needed, better to aim for 0.2Hz and not have to play around with initial acquisition - still well within the capabilities of any crystal oscillator.
 
So to summarise,  by recommending crystal oscillator stabilities you won't be giving any wrong steers - 1 part per million should be the stability people should really aim for, but a factor or so worse than this can still be useable with Spectrogram type modes.
 
I myself use a Direct Digital Synthesizer source driven routinely by a TCXOo scillator adjusted up for a repeatable 0.1ppm.   The DDS tunes in 0.001 Hz steps and without accurate calibration achieves 0.03Hz accuracy, with calibration against off air signals (eg MSF in the UK) 0 .001Hz is possible.  For times when some distant stations actually get set up for some serious experimentation with very narrow band modes, I have Droitwich and TV sync locked frequency sources - both hangovers from microwave operating, (all home station operators and several /P have constructed one or the other of these). All these give a frequency setting accuracy of a few parts in 10^-9 - about 1mHz at 137k.
For calibration purposes, a GPS receiver giving 1s pulses drives the external clock of a frequency counter allowing 1000s / 10ks (2.78 hour) or 100ks (just over 1 day) gating periods.    Also have a Caesium standard but prefer to only turn it on once in a while when needed as the tube is nearing the end of its life and its usefulness for LF is debateable.  For calibration the GPS pulses are traceable to international standards and can be used immediately, whereas the Cs standard would need to be set up each time and run for several days to guarantee its few parts in 10^-11 accuracy.
 
Sorry to sound a bit cynical about LF frequency accuracies and stabilities, but having spent over 10 years with narrowband operation on the microwaves bands,o ften from exposed portable locations, where the 1ppm accuracy that very few LF operators bother to aim for is several SSB bandwidths, I am rather surprised at the difficulties many seem to have and the poor stabilities still being seen on LF now.  At least the disgusting LC oscillator has faded out, but the norm now seems to be two VCXOs mixed, which I suppose is comparable to an LC VFO on the HF bands, not something seen too often now, fortunately.   Up on 10GHz a low cost crystal heater is the minimum anyone ever uses and 1ppm is usually the result.  Operators routinely calibrate with beacons and other stations throughout an operating period and everyone knows at least when they are within a 3kHz SSB bandwidth tuning range.
 
Ironically, HF has the lowest requirement for frequency stability.  With ionosphericp ropagation causing several Hz shifts over minutes, as well as multipath with several millisecond delays, who needs better than 0.2 ppm frequency accuracy?
