I was pleased to read your message about your activities on LF last weekend. I was also pleased that you could hear my signal at 539. I always listen very carefully but did not hear anything from you. I have a very quiet qth but your signal did not stretch this far, otherwise I would have heard you and I have also visual facilites. The antenna here, consists of two inverted L antennas back to back. Each one is 32 metres vertical and each one a top length of 80 metres. Both are connected at the bottom and also connected to a large diamater 1.4mh inductor and a further smaller inductor of 0.2 mh in series to the earth/radial system for fine tuning the system to 50 ohms to feed to the tx/rx. The matching system is at the base of the vertical and about 150 feet of 50 ohm coax is used to feed the TX/RX in the shack. The RX used normally an icom 706 with a 250 hz narrow IF FILTER and an external DSP unit allowing me to narrow the b/w to 20 hz. The TX is home built and consists of dividing 13.6 mhz signal from the ic706 down by 100 to 136khz and is vfo controlled. The divider is followed by a driver and keyer circuit to feed 4 high power mosfets, then into a LPF matching device for 50 ohms. The tx is basically the G3YXM approach with some alterations and is very reliable. The power output is adjustable from 25w to 800w with my power supply, and I normally run just over 600w. I have a comprehensive radial system consisting of a network of insulated 2.5 mm wire on the ground and some elevated. I operate normal CW only on LF although I have computer facilites for slow cw and also psk31 plus all the other digital modes. I am active nearly every day on LF and will listen carefully for signals from OE land. 73 and good dxing de Mal/G3KEV Heinz Schnait wrote: > The 450m wire antenna at OE5ODL, Ossi, is still up!

I hope to be QRV from 03:00 - 05:00 UT, Sunday 5th December on 136.8 kHz, +/- QRM [!], weather permitting. I will call DL1SAN for 5 minutes starting at 03:00 & 03:30. I will listen for DL1SAN for 5 minutes starting at 03:05 & 03:35. Each time, I will listen first on my TX frequency, then carefully tune 136.2 to 137.4 kHz. At other times, I will either be sending CQ calls, or listening for other 'early birds'. (I hope some other TXing/RXing stations will be able to join in the fun too!) To increase the probability of a QSO if copy is difficult, I find that the following procedure works well: 1) start and end the first transmission(s) with 3 x 3 callsigns (e.g. N4ICK N4ICK N4ICK DE GW4ALG GW4ALG GW4ALG); 2) once you are sure that both callsigns have been copied correctly, start and end each over with 1 x 1 callsigns (e.g. ZL4MD DE GW4ALG); 3) if you think that one of the callsigns is in doubt, use 1 x 3; or 3 x 1 callsigns, as appropriate; 4) send two 'K's at the end of each transmission; 5) only send the outgoing report (i.e. do not re-send the incoming report), and send it at least five times at each attempt; and, 6) only send a series of 'R's when you are sure that you have copied the other station's callsign - and your incoming report - correctly.

In addition to the above : if you have a weak-signal sked it can be very usefull to agree on fixed transmit / receive periods. eg : stations A will transmit during the odd minutes, station B during the even minutes. Of course you can also arrange 2 minute periodes (or even longer). At least you avoid that you will be transmitting simultaniuosly. 73, Rik ON7YD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 15844 invoked from network); 5 Dec 1999 23:41:22 +0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by guiness.force9.net with SMTP; 5 Dec 1999 23:41:22 +0000 Received: from majordom by post.thorcom.com with local (Exim 3.02 #1) id 11ul06-0006Hx-00 for rsgb_lf_group-outgoing@blacksheep.org; Sun, 05 Dec 1999 23:23:30 +0000 Received: from carbon.btinternet.com ([194.73.73.92]) by post.thorcom.com with esmtp (Exim 3.02 #1) id 11ul05-0006Hs-00 for rsgb_lf_group@blacksheep.org; Sun, 05 Dec 1999 23:23:29 +0000 Received: from [212.140.34.68] (helo=default) by carbon.btinternet.com with smtp (Exim 2.05 #1) id 11ukzu-0001pS-00 for rsgb_lf_group@blacksheep.org; Sun, 5 Dec 1999 23:23:18 +0000 Message-ID: <001501bf3f77$7b615e20$44228cd4@default> From: "Alan Melia" To: "rsgb_lf_group" Subject: LF: No Cluster spots, so Alan's waffle Date: Sun, 5 Dec 1999 22:47:26 -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: Sorry no new spots to the DX Cluster at all this weekend I hope the wind and snow didn't affect your long high aerials too much. It did not seem to be holding back MM0ALM on Friday evening. Fri 3rd Dec Quite a lot of activity most of the afternoon and evening. I made occasional short sessions listening. 1342 G3AQC calling GI3PDM 1452 G3YXM CQ answered by PA0SE 1519 G6NB CQ 2110 MM0ALM working OH2LYG on 136.3kHz could not hear the OH2 though I seem to remember there was a weak trace on the waterfall display 2219 G3XTZ CQ Late on I think I heard a tune-up from M0BMU which is a call I have not heard before....another new recruit. Sat 4th Dec Streaming cold making listening with the phones unpleasant so concentrated on the visual stuff around 137.7. Particularly as Rik was trialling the dual frequency cw. I found this fairly easy to read and don't think it would have been too much trouble even without the inter-element spaces Rik has added to his spec. Unfortunately Rik was a good signal here and I did not get a chance to see how easy it would be to copy in amongst the noise. There were several other calls from the usual QRSers. I saw the track of a PSK31 signal at good strength on the waterfall at about 2013z but too late to fire up the decoder program. Sun 5th Dec from the overnight log-file (ZZzzeds til 0800z) Activity started at about 0351z so Steve had someone to keep him awake. Dave G0MRF was sending QRS CQs at about the same time. At 0458z Dave's signal faded out during the letters of the 2nd call.....Oh dear it looked rather like the FETs were objecting to being wakened up so early on a Sunday. Big signal from Peter G3LDO at 0757 with a CQ. I didn't see any DX in that period and was just settling to a 2nd coffee and the paper (at 0950z), when a nice clear CQ appeared on the screen. "Ah that looks like PA or ON".....only to see the letters HB9ASB appear at a very good 'O'. I have a nice Spectrogram screen of CQs from Toni and PA2NJN, with Rik and his DFCW in between. Strangely enough Toni was stronger than PA2NJN though to be fair he may have been in a more favourable direction for my loop. Thanks Toni a new heard country for me. Emphasising your reflector comment to me last week that you WERE on QRS. Later in the morning (and I forgot to record the time!) I heard Mal G3KEV working IK5ZPV as did the rest of the UK. I could see a weak trace on the screen with FFTDSP4 so we would copy QRS at 'O' Valerio. What a shame I thought I was in for another new country this morning, but I just could not make out any morse elements in the noise (even with the 80Hz audio filter!). >From the number of calls that followed the end of Mal's qso many others could hear. Heard M0BMU working G6NB at 1200z also heard G4GVC, G8RO. I have a note of PA0MWC working G8RO, no time logged (It could have been at 1920 after I returned home) but this is a new PA call to me. Activity is certainly good at present and it is rare for there not to be a signal on the band at some time during each half hour period of the waking day. And I guess someone is listening.....so keep trying the calls. My waterfall log will run all day, so if you want to experiment drop me an e-mail and I can ensure its on for you. At the moment I can't print or save screens off the replay, but I'm working on it. Does anyone know where one can go to buy Rockwell-Collins filters?? Both Vaino and myself want to go down a step in bandwidth on our AOR 7030s but AOR do not stock the part(listed on the R-C web site as a Low Cost stock part). I have had no response to an e-mail. This seems to be my experience with large American companies....they have web sites but can't find anyone to answer the e-mails they generate. I have compiled a list of locators for the active stations (where I know them) for Vaino and myself to calculate distances. I can mail a copy to anyone who wants one (unless you think that would be cheating!) and would appreciate locators from active stations I do not hear, or who are not included, to add to the list. I will not post it to the relector unless there is an big demand.

Don´t know what happend. May be the snow and ice on the wires caused this change. Did some other measurements on sunday afternoon, when the sun reduced the ice but there was no difference. Nevertheless lets make an other trial the next weekend. What about the same time?

The weather was again the main concern this weeken with everything from gales to sleet - we even got some thunder and lightening on Saturday afternoon! With this, and everyone obviously starting their Christmas shopping, the early part of the weekend was fairly quiet, but there was still enough activity to make the band worth checking from time to time. It was nice to work both Kai and Reino on Saturday night; Kai is now marginally my furthest DX on the band, and has improved his signal so that he is nearly as strong as Reino. Sunday started very quietly (although my noise level was a little higher than usual - frost static??), but then the band got increadibly busy and it became a scramble to work anything. Nevertheless I managed a couple of new ones for me; first Dieter DK5PT and later Jim M0BMU in Hatfield, with a very good signal. This was not only Jim's first LF QSO, but also his first CW QSO! Excellent. It takes my 'first QSO' tally up to 14 with 85 callsigns now worked 2-way on 136kHz.

To All from PA0SE
 
On LF I use a simple audio signal clipper that brings all signals in the headphones to the same level. It may not improve readibility but makes listening much less tiring by limiting all sorts of crashes and other impulsive noises.
I have the clipper always in use and would not do without anymore.
 
The clipper consists of two germanium diodes type OA85 connected anti-parallel over the output of the receiver. To be effective both the voltage and the impedance at the point were the diodes are connected must be sufficiently high. I use passive audio bandpass filters between receiver and headphones and the diodes are connected over the first tuned circuit of the filters where impedance and voltage are high enough. (Do not put the clipper behind the filter.)
 
When you use low resistance headphones the system will not work. Perhaps you can find a suitable point for the diodes in the audio section of the receiver: for instance the voltage over the volume control may be high enough for the purpose.
 
If you find in your junkbox a pair of old valve-type audio output transformers (for example with a ratio of 5000 to 8 ohms or thereabouts) you could connect the high impedance windings together and put the diodes there as well. The low impedance windings are connected to the receiver output and the headphones respectively.  
 
I also tried anti-parallel diodes in series with the receiver output as advocated by Jan Smeets, ON4ASZ/EA3DPD ("Technical Topics", RadCom, March 1998) hoping they would improve readability of weak signals in noise. The idea was that the output level of the receiver would be adjusted so that signal + noise would just overcome the threshold voltage of the diodes and the noise alone not. But it did not work. Understandable in retrospect, considering the wide amplitude variations of noise.

Early morning tests ******************* The band was very 'quiet' during the entire test period of 03:00 - 05:00 UT. There was virtually no QRN, and the background noise was very low - rather like listening to 136 kHz during the day. No signals from outside 'G' were heard. I am grateful to Mike; Laurie; and David for their reports. I know that Laurie G3AQC has done some great work in improving his signal recently, but the signal from Laurie at 03:18 seemed to be even stronger (by about 1 S-point) than his daytime signal. The signal from David G0MRF also seemed to be slightly up on his normal daytime signal strength. During the tests, I had a funny feeling that my signals were getting further than G-land. So I am still keen to try further tests. Skeds welcome. Noise canceller *************** I'm still preparing some details about an LF version of the VK5BR noise canceller.

No recent changes to my TX ant but xmit pwr increased to 250/300 Watts fron 29/11/99.So possibility is that any increase in sig strength due to this.Unfortunately my Rx ant was faulty, so recieved signal strength not significant.I guess we would need to do further tests,but I dont know wether I could force myself out of bed again! HI.
Many thanks Steve for the info on your Web site,most intresting and informative.

To use a DFCW 'subband' from 137650Hz to 137695Hz, this will avoid collosions with QRSS actovity that is mainly between 137700Hz and 137800Hz. 2. To use a frequency shift of 4Hz. At this moment this seems to be narrow enough to minize the bandwidth of DFCW and wide enough to be properly separated by receiveing software as GRAM. Als a 4Hz shift is easy to implement with PLL-VFO systems that work in 1Hz steps (as you just have to toggle the 3rd byte). 3. To use a 'channel spacing' of 10Hz. This would mean that we have 5 'channels' going from 137650/137654Hz to 137690/137694Hz. Working with 'channels' will minimize interference between DFCW signals while the 10Hz 'step' is enough to separate 2 DFCW signals even if there is a slight drift on one of the transmitters. 4. To use a 3 second 'element length' separated by a 1 second 'gap'. From QRSS we know that 3 seconds dot length is optimal for most receiving software. The 1 second 'gap' will make visual detection of the signal easier and also reduce the dutycycle a bit, avoiding overheated PA's. 5. To introduce following practice for weak signal work : If you receive a CQ from a station and you are not sure to be 'seen' at the other end, just send a 'KK'. If the other station can read the 'K' it should reply the with 'RR' as confirmation. After that the station that sent the 'K' can reply to the CQ. This procedure is suggested by Markus, DF6NM, and can pervent idle transmissions and useless QRM. eg.

This is especially important if KK and RR are to be sent as part of the procedure, as a K is an upside down R !! I have suggested this before, and it has not been taken up, but I think that transmissions should start with CT (as one word). This will make it very easy to determine which element is the dash, and to find the dot length - bear in mind that there is a 4dB advantage to be gained by using element lengths of 10s or so, The use of CT is quite normal to indicate the start of commercial CW traffic so will not be ambiguous.

Mike is right, that is the one thing I forgot to mention : 'dash' should be the higher frequency, 'dot' the lower frequency. Regarding 'CT' : our CQ wil do the job too, during a QSO it might be usefull to start transmission with 'CT' but so far I had no problem in 'decoding' DFCW signals without this. Anyway, for those who like 'CT' (-.-.-) I will add it to the 'extra characters' in the QRS software. 73, Rik ON7YD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 12006 invoked from network); 9 Dec 1999 16:56:59 +0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by guiness.force9.net with SMTP; 9 Dec 1999 16:56:59 +0000 Received: from majordom by post.thorcom.com with local (Exim 3.02 #1) id 11w6iS-000349-00 for rsgb_lf_group-outgoing@blacksheep.org; Thu, 09 Dec 1999 16:46:52 +0000 Content-Transfer-Encoding: 8bit Received: from mail.cc.kuleuven.ac.be ([134.58.10.6]) by post.thorcom.com with esmtp (Exim 3.02 #1) id 11w6iO-000343-00 for rsgb_lf_group@blacksheep.org; Thu, 09 Dec 1999 16:46:48 +0000 X-Priority: 3 X-MSMail-Priority: Normal 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 RAA126148 for ; Thu, 9 Dec 1999 17:46:37 +0100 Message-ID: <3.0.1.16.19991209184539.22379c12@mail.cc.kuleuven.ac.be> X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 X-Sender: pb623250@mail.cc.kuleuven.ac.be X-Mailer: Windows Eudora Pro Version 3.0.1 (16) Date: Thu, 09 Dec 1999 18:45:39 To: rsgb_lf_group@blacksheep.org From: "Rik Strobbe" Subject: LF: QRS version 2.03b 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 new new beta version of QRS ready (2.03b).

I'm wondering if > looped tie-wraps would be strong enough as there is quite a lot of > tension in each section of my antenna. > Well, I originally used a white plastic water pipe wrapped with black plastic tape as a spreader for the three top wires. The plastic tape was used to make the spreader less visible to keep the neighbours happy. When the current was disappointingly low, I added the looped cable ties between the wires and the spreader, and improved the insulation and the current. As for strength, the weak point of a cable tie is the plastic ratchet and I do not rely on it. I tie a knot in the free bit of the tie after it has gone through the ratchet, then wrap that part of it with tape. Rik suggests that UV may cause deteoration which is certainly worth bearing in mind, though it would not break the bank to replace them every year. If you use two, or even three, the effective insulation increases dramatically as the area of contact between them is very small. I use them in pairs and notice no difference in the current, wet or dry. Do not use plastic twine - I did this and wondered why the antenna fell down every time I keyed the transmitter in the rain. The plastic simply melted!

There are cable ties and cable ties. It is possible to buy very cheap ones but in my experience these are not really intended for exterior use, and are NOT UV proof. Choose a good 'exterior' grade of tie and you may even get 'UV-proof' in the spec. We use black ones but I am not sure whether this affects the loss/insulation properties, as we only use them for cleating up coax. In practice the black ones seem to last longer than the white ones. I have seem these ties last 10 years high up a tall mast, and still have to be cut off when the cable was replaced. I don't know how you use these as insulators, but could I suggest 'doubling up' so one tie takes the tension and a second (not under tension) acts as a safety in case the first snaps. It might save a few FETs!! or in Dave's case loading coils! The other problem is this sort of plastic doesn't like being 'creased' as thhis will reduce its strength considerably. So some attempt must be made to limit the curvature at the ends, and stop it folding.

Re. Insulators, it ought to be possible to check plastic by the same means as used for coil formers.Put a sample of the plastic in the microwave with a cup of water.Run for a minute or two, water should be hot but plastic remain cool!Assuming you can find a suitable plastic(toothbrush,water pipe etc) only remains to ensure a long smooth path from end to end so that water runs of

I know this! A good point. I've experienced similar problems with tubes when used as insulators. During a telephone conversation with Bill G0AKY, he described a similar 'trick' to that described by Dave G3YMC. Bill cuts his round white plastic tube (e.g. gutter down-pipe, up to 100 mm diameter) into lengths about 30 mm long. He then uses heat to soften the sections into an oval shape. I suppose the overall result is rather like using a cable tie, but may be more UV resistant than the common type of cable tie.

Is this a Mellenium wind up. If you cannot get proper antenna insulators from the normal radio suppliers, sensible options are available at marine or farmers suppliers. The Marine insulators available at ships chandlers or yacht suppliers look like a dogs bone and are about 100mm long with eyes each end 20mm diamater, white in colour, polypropylene material, and are strong and light. There is also a larger version if required. The Farmers type are used for electric fencing, there is a variety of types and are green or black, strong and light. For low power applications you can use small plastic blocks, available at DIY stores. These are normally used for building cupboards and have a hole at each end and one at right angles in the middle. Size about 30mm long and 8 mm wide. I have used all of these items as insulators up to very high voltages and to date never had a failure or burn up. Also available at yacht suppliers are a variety of marine grade polypropylene strong ropes for guying towers and being non conductive are ideal. Wire for antennas in 600 metre rolls can be obtained from Farmers suppliers this is normally used for electric fencing and consists of several strands of stainless steel wire interleaved with plastic strands but there is a variety that has two strands made of COPPER and could be suitable for antennas. .Hope you find the above information useful de MAL/G3KEV From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 26369 invoked from network); 12 Dec 1999 19:59:30 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by 212.159.2.33 with SMTP; 12 Dec 1999 19:59:30 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.02 #1) id 11xFX8-00014Y-00 for rsgb_lf_group-outgoing@blacksheep.org; Sun, 12 Dec 1999 20:23:54 +0000 Received: from mta3-rme.xtra.co.nz ([203.96.92.13]) by post.thorcom.com with esmtp (Exim 3.02 #1) id 11xFX6-00014R-00 for rsgb_lf_group@blacksheep.org; Sun, 12 Dec 1999 20:23:53 +0000 Received: from locxvcym ([210.55.121.111]) by mta3-rme.xtra.co.nz (InterMail v4.01.01.00 201-229-111) with ESMTP id <19991212195104.NGWJ27648.mta3-rme@locxvcym> for ; Mon, 13 Dec 1999 08:51:04 +1300 From: "ComPact" To: rsgb_lf_group@blacksheep.org X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Subject: LF: Re: Insulators Date: Mon, 13 Dec 1999 08:53:38 +1300 X-MSMail-Priority: Normal X-Priority: 3 X-Mailer: Microsoft Internet Mail 4.70.1161 MIME-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 8bit Message-ID: <19991212195104.NGWJ27648.mta3-rme@locxvcym> Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Another useful item at the farmers supply shops is one metre long fiberglass rods which make very good spreaders for multi-wire top loading.

The antenna had been lowered all week due to the winds and I re-rigged it at lunchtime on Friday. Static levels were fairly high and it started pouring with rain just as I began the contact with Reino, so the antenna efficiency dropped during the QSO. The heavy rain continued right through until Saturday afternoon, so I didn't bother to do any transmitting until later, and even then the antenna current was lower than normal due to the waterlogged ground. I left the RX scanning whilst I got on with other things, but the level of activity seemed well down on normal. Sunday started dry here, but the rain quickly returned and the day became more or less a repeat of Saturday - not a very productive weekend. As an aside, on Friday night I remembered to listen to the special morse broadcast from DDH47 on 147.3kHz, which made an interesting change to the usual work on LF. I was surprised how complex the transmission was, with the "poineer names" embedded within messages in German, English, French and Italian, sent at three different power levels (15, 5 & 1KW) and two different speeds (moderate and fast!), which lasted over an hour. They certainly make you work for your certificate! As expected, the signal was enormous on my LF antenna - well over S9 at the 1KW level and very different to the milliwatt erp signals we are used to copying 10kHz lower!

I took some time for reading and found a couple of interesting formulas for calculating the 'free space' capasitance of wires : 1. Horizontal wire : C(pF) = 0.24 x Er x L(cm) / log(4 x H / D) where Er = relative diëlectric constant (1.0006 for air), L = wire length, H = wire height and D = wire diameter 2. Vertical wire high above ground : C(pF) = 0.24 x Er x L(cm) / log(L / D) 3. Vertical wire close to ground (H << L/4) C(pF) = 0.24 x Er x L(cm) / log(1.15 x L / D) I made some calculations for a 3mm thick wire and the results are very acceptable : For a horizontal wire I got a capasitance of 7.7pF/m at 1m height, decreasing to 6.3pF/ at 5m height, 5.8pF/m at 10m height and 5.2pF/m at 30m height. For horizontal wires starting at ground level I got 9.3pF for a 1m heigh wire (average 9.3pF/m), 36.6pF for a 5m heigh wire (average 7.3pF/m), 67.0pF for a 10m heigh wire (average 6.7pF/m) and 177.3pF for a 30m heigh wire (average 5.9pF/m) 73, Rik ON7YD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 24770 invoked from network); 13 Dec 1999 11:12:53 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by 212.159.2.33 with SMTP; 13 Dec 1999 11:12:53 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.02 #1) id 11xToq-000681-00 for rsgb_lf_group-outgoing@blacksheep.org; Mon, 13 Dec 1999 11:39:08 +0000 Received: from man-114.dialup.zetnet.co.uk ([194.247.40.146] helo=localhost.localdomain ident=john) by post.thorcom.com with esmtp (Exim 3.02 #1) id 11xToo-00067w-00 for rsgb_lf_group@blacksheep.org; Mon, 13 Dec 1999 11:39:06 +0000 Received: (from john@localhost) by localhost.localdomain (8.9.3/8.9.3) id SAA12160 for rsgb_lf_group@blacksheep.org; Sun, 12 Dec 1999 18:39:02 GMT X-MSMail-Priority: Normal X-Authentication-Warning: localhost.localdomain: john set sender to word.factory@zetnet.co.uk using -f Message-ID: X-Mailer: XFMail 1.3 [p0] on Linux X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 X-Priority: 3 Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 8bit MIME-Version: 1.0 In-reply-to: <3853A88D.58495524@netscapeonline.co.uk> Date: Sun, 12 Dec 1999 18:39:02 -0000 () From: "John Rabson" To: rsgb_lf_group@blacksheep.org Subject: RE: LF: (no subject) Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: On 12-Dec-99 malcolmg3kev wrote: > Wire for antennas in 600 metre rolls can be obtained from Farmers > suppliers this is normally used for electric fencing and consists of > several strands of stainless steel wire interleaved with plastic strands Carefulll!

The problem is that the garden is rather short and so I have had to bend the ends of the G5RV downwards. The top is 64 feet and so each end descends 19 feet. If I were to use the antenna as a top-loaded vertical, I would probably have to chop off these two descenders, which would probably ruin its low-angle radiation for HF. The ends come down to about 7 feet above ground and so it is easy to attach another 64 feet or so of wire a couple of feet above ground to complete the loop. It is then fed via the vertical feeder to the centre of the top. At the bottom of the feeder will be a water-proof box containing alternative matching to heavy gauge 50 ohm coax (Mr Westlakes best) for either HF or LF. To operate on HF, I would have to disconnect the lower part of the loop and switch to an HF balun. For LF reconnect the lower loop and switch to a Loop Tuning Unit as described in Steve Rawlings home page. He has kindly given me pointers to sources for components. Ideally the switching might be made using high voltage relays as in the article on Transmitting loops on page 2.25 of the LF Source Book, but initially I would do it manually. The principal problem I have found during initial tests, is that the DC resistance of 300 ohm feeder (best quality air spaced) is 0.7 Ohm for 34 feet - very high! So I am making my own out of 50/.25 wire with 3inch spreaders, which will reduce it to about a tenth of this figure. By the way can anyone complete the graph of RF resistance against frequency from Les Moxon's book (HF antennas for all Locations fig 3.10) for the bit of interest between 1 MHz and 0Hz. The graphs are shown as straight lines, with the resistance increasing with decreasing frequency, but it must turn over at some point in order to come down to the DC resistance at 0Hz. This must be a problem others have faced, how to use a single antenna for both HF and LF - but I haven't seen any discussion about it. Nice to meet you on the air for the first time, all be it not on 136 yet, but I have heard you on that band many times, including twice on Sunday, when you were S8 here in Reading despite the fact that the RX loop is East-West at the moment. 73s John, G4CNN, IO91ML _______________________________________________________ Get FREE voicemail, fax and email at http://voicemail.excite.com Talk online at http://voicechat.excite.com From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 4835 invoked from network); 13 Dec 1999 18:21:18 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by 212.159.2.33 with SMTP; 13 Dec 1999 18:21:18 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.02 #1) id 11xaRk-00004s-00 for rsgb_lf_group-outgoing@blacksheep.org; Mon, 13 Dec 1999 18:43:44 +0000 Received: from helios.herts.ac.uk ([147.197.200.2]) by post.thorcom.com with esmtp (Exim 3.02 #1) id 11xaRj-00004m-00 for rsgb_lf_group@blacksheep.org; Mon, 13 Dec 1999 18:43:43 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from [147.197.200.44] (helo=gemini) by helios.herts.ac.uk with esmtp (Exim 3.11 #1) id 11xZuJ-00011M-00 for rsgb_lf_group@blacksheep.org; Mon, 13 Dec 1999 18:09:11 +0000 Message-ID: <28661.199912131815@gemini> From: "James Moritz" X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Organization: University of Hertfordshire To: rsgb_lf_group@blacksheep.org Date: Mon, 13 Dec 1999 18:15:42 +0000 MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII; format=flowed Content-Transfer-Encoding: 8bit Subject: LF: M0BMU - First week on LF X-Mailer: Pegasus Mail for Win32 (v3.11) Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Dear All, Many thanks to all the stations who have worked me during the last week or so, for the very warm welcome I have received, and their patience with my patchy morse capabilities! It has made all the work involved in getting on LF thoroughly worthwhile. Some details of my station: Location: Brookmans Park, near Hatfield, Herts - just across the road from the well known MF broadcast site - locator IO91VR. Please note - the address in the call book is now superceded - but any mail to that address will be re-directed OK for the forseeable future. TX: 100W from VFO & modified Maplin mosfet audio amp - manual CW only at the moment. RX: Homebrew superhet covering 0-150kHz. About 400Hz bandwidth. Antenna: Inverted L, 30m long and 5m high, two wires in top section, joined at feed end and spaced 4m apart at far end. About 8 ground rods spread around garden. Matching by adjustable series loading coils, and multi-tapped ferrite cored transformer. Aerial current 1.4A Best DX to date - GW4ALG, PA0SE, MM0ALM, ON6ND. Regarding the discussion on insulators, I am using W.H.Westlake's 4 inch "dog bone" insulators (see RadComm) - these are made of some resilient black plastic, seem to be very strong, and I have experienced no problems operating in the wet. I realise that I am running quite QRP compared to some stations, but they are light enough to string 2 or 3 in series if breakdown were a problem. They seem quite a good deal at 75p. I have also been playing with 10m telescopic fiberglass poles, of the same type shown on GW4ALG's web pages, to prop up the middle of my antenna and so gain a few metres. Like Steve, I found these whipped about in the wind a lot, but have now guyed them using monofilament "strimmer line" from a garden shop, tied round the antenna wires with no further insulation. These were not harmed by operating in the rain either, even with the key held down continuously for 30 seconds. I expect to be on LF on several days over the holiday period - hope to hear you there!

Don't do it, especially on VLF. Use a single antenna for each band. It is difficult enough to get max efficiency on 136 using an antenna specifically built for the band, anything else is a compromise and would result in poor and disappointing results. The same applies to 160 metres. If you are serious about vlf achievements look for a small farm in the country and large antennas. Good insulators from marine/yacht outlets only cost 35 pence each. Why bother about toothpicks, hard boiled eggs and shoe laces. A tooth brush would cost more and melt down at about 11 watts when dry, and less when wet. 73 de Mal/G3KEV john sexton wrote: > Hi Dave, G3YXM, > > Just to finish our brief discussion yesterday on the Lowfer's Net, my reason > for trying a transmitting loop first is so that I can operate on both HF and > LF without having to put up two antennas. > > The problem is that the garden is rather short and so I have had to bend the > ends of the G5RV downwards.

It's just that my aerial in GM is held up with old toothbrushes and It happily takes a kilowatt in the rain and has done for 9 months, sorry about that. I just wanted to pass on an eco friendly tip, I bet they're lighter than ship's insulators as well.......... To John. You'll certainly have to minimise the resistance in the loop and feeder before it will work OK but by all means give it a try, the results will speak for themselves.

We haven't worked yet, but no doubt will soon as I am your nearest local. Actually, I'm insanely jealous as you are already getting the same reports as me and it took me two years to get to that level - and all with just 100W and a low antenna. And 1.4A from a 100W Tx? My 200 watter produces 1.7A so your antenna must have a lower impedance than mine. I suspect the proximity to Brookman's Park BBC helps as you may well be benefitting from the earth mat and possibly even some parasitic radiation from the masts/antennas (for those that don't know, it is an MF station with verticals and a big Marconi T). Anyway, congratulations on a good start and welcome to the friendliest band there is. > I have also been playing with 10m telescopic fiberglass poles, of > the same type shown on GW4ALG's web pages, to prop up the > middle of my antenna and so gain a few metres.

Hello friends
 
Sunday 28/11 I have contacted OK1FIG in visual CW and Petr has inserted the spectrogramm on his gallery.
In spite of my very low ERP power ( only 15 or 20 milliwatts), the signal appears quite strong, even if it moves up and
down on the screen. In fact my RTX was drifting terribly and I was compelled to correct continually the frequency.
Now I have built a new gear with a very stable oscillator and I hope in the future my signals will be not so swinging!!

Of course we should not ignore the experience of the profs but the day we stop experimenting and looking for alternative ways ham-radio looses a major reason of its existence. About 2 years ago, when I started with LF, I talked with an engeneer with long year experience in broadcasting. When I told him about our 1W ERP limit he laughed and said that I never would get any further than 10, maybe 20km. The distance record is meanwhile over 2200km. So don't stop experimenting, regardless wether it is about isolators, alternative antennas or alternative transmission modes. That we often have to 'get of the beaten track' is one the things I like most on LF. 73, Rik ON7YD At 18:54 14/12/99 +0000, you wrote: >Re - experimenters band. >The Broadcaster fraternity and Admirality engineers pioneered, and have been >using the Low frequencies for 50 years very successfuly.

Most studies on LF propagation have concentrated on the ground wave mode and little data and analysis exist on sky wave propagation. J.S. Belrose et al presented data on LF skywave propagation in the Proceedings of the IEEE in May of 1959. This paper seems to be the best source of data on the subject. AMRAD is looking at acquiring data on European LF broadcast stations to help engineer the system necessary to achieve a transatlantic QSO on LF. Some early data has been collected by Sandy, WB5MMB and is shown here. Note the abrupt drop in signal level around 0700 GMT which corresponds with sunrise in the area of the transmitter. We are curious to know what other phenomena might be exploited to achieve a transatlantic QSO. The equipment consisted of an e-field probe on the roof of a 3-story building, and a military "Cubic 3030" receiver.

I can supply against cost of shipping a limited number of professional quality aerial insulators.
They are dog bone shaped (a centre part of 2.5 cm diameter with 3.5 cm diameter ends with  holes), They are made of brown porcelain, distance between holes 16 cm, mass 180 gram.
 
If you are interested send me an e-mail with the number you want.
 
Dave, G3YXM, has offered to act as distribution point in case more than one "order"comes in from the UK.

The situation is more complicated than I previously announced. In fact, the ART (French equivelant of OFTEL) has made several demands towards the Agence Nationale des Frequences (French equivalent of the RA) regarding the use of the 136 kHz band in France by amateurs. I phoned the ANF, and nobody there seemed to know what I was talking about! Well, I'm one of those "bad" journalists who never give up: I gave a call to the ministry. The minister didn't want to speak to me so they connected me to the press service. Again, nobody was able to understand a word about what I was talking about (are we lowfers so bizarre?). Finally, after five phone calls, around eight or nine different services, fifteen or so different people and twenty-five times explaining the same thing, I managed to get a short piece of information from an official source. Read this: "the 136 kHz band will definately be allocated to the amateur service in France. I'm surprised that so many european countries are already active. However, our request has been published. All we need now is a signature from the Prime Minister. He does have the papers on his desk since a couple of months. The question is, how many papers have been loaded on top of the 136 kHz file..." So, 136 in France can be authorised tomorrow, like it can be authorised in December 2000. However, we're quite sure right now that it will be authorised whatsoever. Wait and see. 73, Mark, F6JSZ Editor, French CQ From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 1157 invoked from network); 16 Dec 1999 15:44:56 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by 212.159.2.33 with SMTP; 16 Dec 1999 15:44:56 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.02 #1) id 11ydVc-0004pw-00 for rsgb_lf_group-outgoing@blacksheep.org; Thu, 16 Dec 1999 16:12:04 +0000 Content-Transfer-Encoding: 8bit Received: from server.italway.it ([193.70.27.5] ident=root) by post.thorcom.com with esmtp (Exim 3.02 #1) id 11ydVb-0004pr-00 for rsgb_lf_group@blacksheep.org; Thu, 16 Dec 1999 16:12:03 +0000 Received: from allstars (access25.italway.it [193.70.27.124]) by server.italway.it (8.9.3/8.9.3) with SMTP id RAA24092 for ; Thu, 16 Dec 1999 17:33:52 +0100 X-Priority: 3 X-MSMail-Priority: Normal Message-ID: <3.0.1.32.19991216164207.006960f8@mail.italway.it> X-Sender: i5mxx@mail.italway.it (Unverified) X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 X-Mailer: Windows Eudora Pro Version 3.0.1 (32) [I] Date: Thu, 16 Dec 1999 16:42:07 +0100 To: rsgb_lf_group@blacksheep.org From: "i5mxx-Marzio" Subject: Re: LF: New CQ Award In-reply-to: <385824B1.DDC41047@club-internet.fr> References: <38580EF6.D5245005@bellatlantic.net> 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: Hello Mark!

I think this division will incentive a lot traffic and efforts from all amateur peoples involved in LF work, cause real different way and difficulties to manage a qso with a station in QRSS or in normal speed cw. 73 de Marzio I5MXX In 01.52 28/08/70 +0100, hai scritto: >Hello! > >The interest in LF and VLF transmissions is growing and the sole >messages on this list regarding record breaking contacts are there to >prove that. > >Well, as CQ has a long tradition in sponsoring various DX awards, as >CQ-F (the French language edition) is already the sponsor of the CQ >EU-YL Award, we were just thinking about some sort of award for "lowfers". > >Before we get some rules down on the paper, I thought that it would be a >great idea to ask those who are athorised to transmit on these >frequencies to send me their comments about such an award, and what kind >of rules (limitations?) they would like to see. > >Feel free to discuss this topic on this mailing list, or send me your >comments directly. > >73, Mark, F6JSZ >Editor, French CQ >Avid LF Listener > > From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 631 invoked from network); 16 Dec 1999 16:25:14 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by 212.159.2.35 with SMTP; 16 Dec 1999 16:25:14 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.02 #1) id 11ye7r-00050p-00 for rsgb_lf_group-outgoing@blacksheep.org; Thu, 16 Dec 1999 16:51:35 +0000 Received: from hermes.iol.cz ([194.228.2.36]) by post.thorcom.com with esmtp (Exim 3.02 #1) id 11ye7p-00050h-00 for rsgb_lf_group@blacksheep.org; Thu, 16 Dec 1999 16:51:33 +0000 Received: from dell1.GMC.NET ([194.228.133.41]) by hermes.iol.cz (Post.Office MTA v3.5.3 release 223 ID# 631-64078U55000L55000S0V35) with ESMTP id cz for ; Thu, 16 Dec 1999 17:18:34 +0100 Received: from p (P.MALY [192.168.1.35]) by dell1.GMC.NET with SMTP (Microsoft Exchange Internet Mail Service Version 5.5.2650.21) id YR5ZQCDN; Thu, 16 Dec 1999 17:21:18 +0100 Message-ID: <003c01bf47e1$95899a20$2301a8c0@maly.gmc.net> From: "Petr Maly" To: rsgb_lf_group@blacksheep.org References: <383CEEAC.71F1E02F@club-internet.fr> <012501bf43e5$dcf0bec0$0600a8c0@main> <3854B5A4.E96DBDFC@club-internet.fr> <003801bf45a2$bd0fa1c0$0600a8c0@main> <3858FDF5.754B0F11@club-internet.fr> Subject: LF: getting permission OK Date: Thu, 16 Dec 1999 17:21:03 +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 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: Hello Lowfers Nice story, isn't it.

Hi Tom. You are correct, anything out side will suffer eventually, it will either rust, corrode or in the case of the ropes discussed will degrade and get brittle. They should be replaced every couple of years and do not wait until they fall down or break. I replace my ropes and insulators frequently even though they look good. I have just spent today refurbishing my antenna system and have increased the height to about 110 feet vertical, and added another inv L. I now have 3 inv L's in parallel. each one is 110 ft vertical and 250 ft top section. These all feed to a common point and connected to my loading inductor, I also replaced the insulators, heavy duty marine type, as before and guaranteed no melt down. I use a minimum of 2.5 mm insulated antenna wire and change this also frequently to avoid a breakage. The refurbished system was re-resonated and tested this afternoon and I got a 599 report from GI3PDN, the effort was worth it. 73 de Mal/G3KEV Tom Boucher wrote: > >From Tom, G3OLB > > Be careful using polypropylene as guys for masts over a long period. > They degrade with ultra-violet exposure and become very weak.

The report by Andre Kesteloot on 15/12/99 re LF propagation prompted me to read some old IEE journals of the late 1940s when there was much intrest in VLF.There are an enormous number of refs and I have access to only a few  of them but it seems a great deal of work was done on LF propagation.Some conclusions are:-
Variations in signal strength mainly due to interference between steady ground wave and multiple reflections from the ionosphere.Height of the reflecting layer being 65-82Kms.Very great variations at sunrise/sunset(indeed for 1-2hours before these events)Other sources of variation due to SIDs and major mag. storms
The reflection height seems to be higher at night by some 12-14Km in winter and 15-17Km in summer.Most of this work was done at frequencies of 16-70Khz using the Decca chain but it was noted that the effects were more marked at 127Khz.Relating all this to the possibility of transatlantic QSOs it seems that there will be no ground wave so we are only concerned with the reflected wave and therefore the height of the ref.layer,but at only 60-80Kms the number of hops will be very great and thus the distance the waves have to travel!  can anybody do the spherical geometry to work this out?What about the losses at each reflection? fortunately over sea so not too great.But it should be possible to put this all together and work out the total path loss.One more thing it seems to me that the best time for long distance contacts will be at night with the mid path being at the centre of the sunset/sunrise periods at the ends  of the path.Well theres a lot to think about here,but why not ,and who knows we might do it! so thanks Andre for stimulating these thoughts.    73s Laurie.

As far as I remind my maths the 'skip distance' should be : D = 2 x 111 x arccos( R/(R+H)) Where D = skip distance (km), R = earth radius (6366km), H = layer height (in km). For a height of 60km the skip distance would be 1724km, for a height of 80km it would be 1988km. But the above assumes that the take-off angle is 0 degrees. Since vertical polarized signals at this frequency tend to 'bend' arround the earth (groundwave) they might not (or very little) escape into the 'sky'. If you have higher radiation angles then the skip distance becomes considerably shorter. 73, Rik ON7YD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 16714 invoked from network); 17 Dec 1999 17:39:37 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by teachers.core.plus.net.uk with SMTP; 17 Dec 1999 17:39:37 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.02 #1) id 11z1ha-0004aK-00 for rsgb_lf_group-outgoing@blacksheep.org; Fri, 17 Dec 1999 18:02:02 +0000 Received: from cmailg3.svr.pol.co.uk ([195.92.195.173]) by post.thorcom.com with esmtp (Exim 3.02 #1) id 11z1hZ-0004aF-00 for rsgb_lf_group@blacksheep.org; Fri, 17 Dec 1999 18:02:01 +0000 Received: from modem-46.scholar.dialup.pol.co.uk ([62.136.142.46] helo=lvm) by cmailg3.svr.pol.co.uk with smtp (Exim 3.12 #0) id 11z1CM-0007VJ-00 for rsgb_lf_group@blacksheep.org; Fri, 17 Dec 1999 17:29:47 +0000 Message-ID: <000201bf48b4$45279b80$2e8e883e@lvm> From: "LAWRENCE MAYHEAD" To: "rsgb lf group" Subject: LF: Re.QRS and Spectrogram.

Crab Pot Spinners alias INSULATORS. These are available at marine suppliers and are ideal for insulators. They are white and appear to be made from a plastic type material and look like a dog bone. There are two sizes. 1. 60mm long, 25mm wide, 10mm wide with eyes at each end to attach antennas. 2. 80mm long, 30mm wide, 15mm wide. The cost is 35 p and 45 pence respectively and are ideal for the LF antenna experimenter where high voltages occur. I use these devices and have not suffered any MELT down situations over the past several years. If anyone needs such devices and cannot get them locally, especially land locked experimenters, I will try and help. I have modified my antenna system and now have 3 inverted L systems in parallel. Each one is 32 metres vertical and each one has an 80 metre top section. The three converge at the bottom of my tower, to a common connector, which is connected to the top of my base loading inductor, the bottom of which is connected to my ground/radial system. This inductor is configured to match a 50 ohm coax feed to the shack which is located 50 meters away and matches the TX/RX 50 ohms. The system is tuned on the nose for a 1:1 swr at the desired operating frequency. 73 de Mal/G3KEV From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 9565 invoked from network); 17 Dec 1999 19:29:36 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by 212.159.2.33 with SMTP; 17 Dec 1999 19:29:36 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.02 #1) id 11z3QN-00059Q-00 for rsgb_lf_group-outgoing@blacksheep.org; Fri, 17 Dec 1999 19:52:23 +0000 Received: from mailhost.netscapeonline.co.uk ([194.200.20.13]) by post.thorcom.com with esmtp (Exim 3.02 #1) id 11z3QM-00059L-00 for rsgb_lf_group@blacksheep.org; Fri, 17 Dec 1999 19:52:23 +0000 Received: from userbu73.netscapeonline.co.uk ([62.125.146.56] helo=netscapeonline.co.uk) by mailhost.netscapeonline.co.uk with esmtp (Exim 3.02 #1) id 11z2vB-00044x-00 for rsgb_lf_group@blacksheep.org; Fri, 17 Dec 1999 19:20:09 +0000 X-Priority: 3 X-MSMail-Priority: Normal Message-ID: <385A8C66.F7C80150@netscapeonline.co.uk> Date: Fri, 17 Dec 1999 19:17:58 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 From: "malcolmg3kev" Organization: Netscape Online member X-Mailer: Mozilla 4.6 [en-gb]C-CCK-MCD NetscapeOnline.co.uk (Win95; I) X-Accept-Language: en-GB,en MIME-Version: 1.0 To: rsgb_lf_group@blacksheep.org Subject: LF: new 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: Two new ones recently worked dj8wx and pa0kdm, but maybe someone else has worked them before.

The signal falls very steeply from this peak. I think Geri has a longer recording on his web site. Unfortunately CFH has been off air since a short burst of activity in September, and I have not found another identifyable reliable source to monitor yet. 73 de Alan G3NYK Alan.Melia@btinternet.com From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 6465 invoked from network); 18 Dec 1999 06:59:32 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by 212.159.2.33 with SMTP; 18 Dec 1999 06:59:32 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.02 #1) id 11zEGE-0000a9-00 for rsgb_lf_group-outgoing@blacksheep.org; Sat, 18 Dec 1999 07:26:38 +0000 Received: from mta00.talk21.com ([62.172.192.40] helo=t21mta00-app.talk21.com) by post.thorcom.com with esmtp (Exim 3.02 #1) id 11zEGC-0000a4-00 for rsgb_lf_group@blacksheep.org; Sat, 18 Dec 1999 07:26:37 +0000 Received: from dave ([213.1.12.139]) by t21mta00-app.talk21.com (InterMail vM.4.01.02.00 201-229-116) with SMTP id <19991218065312.ENBF7774.t21mta00-app.talk21.com@dave> for ; Sat, 18 Dec 1999 06:53:12 +0000 Message-ID: <000b01bf4924$b7163740$8b0c01d5@dave> From: "Dave Sergeant" To: "rsgb_lf_group" Subject: LF: 136 Propogation Date: Sat, 18 Dec 1999 06:42:54 -0000 MIME-Version: 1.0 Content-Type: text/plain; charset=Windows-1252; 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: >From Dave G3YMC The mails from Laurie and Rik on this subject are interesting.

It also explains why the better equipped G stations can relatively easily work Reino, whereas those of us with more modest set-ups with relatively low antennas (and high angle radiation) have difficulty even hearing him.

Well, I thought with my telescopic fibre glas mast lowering it doen and re-erecting should be a matter of minutes. Now, hours later, my experience has helped me to discover some essential basic laws: Geri's laws for erecting wire antennas ============================ - When erecting an antenna tower with guy wires or top loads, each of the wires wire will get caught wherever possible. - The probability for a wire to get caught is at least exponential to the total number of wires used. - The probability of one single wire to get caught at a specific place is directly reciprocal to the acessibility of that place. - If there is a slight chance that you might need a ladder, you will need it. BTW: My antenna is back in the air I am QRV again.

The WA2XTF/12 beacon on 136.745 kHz is a part of the Amateur Radio Research and Development Corporation's experiments to gain LF experience in anticipation that the FCC may allocate an amateur band at 136 kHz. In October 1998, the ARRL petitioned the FCC to create two amateur LF allocations at 135.7-137.8 kHz and 160-190 kHz. Its petition was designated RM-9404. The FCC has not yet acted on the request. The new beacon at the QTH of Ted Seely, AA4GM, near Front Royal, Virginia--one of 12 WA2XTF sites--features a 175 W transmitter feeding a 1600-foot horizontal antenna. It transmits a continuous CW message at 5 WPM. The AMRAD project's first beacon WA2XTF/6, on 136.75 kHz, was shut down temporarily to eliminate the potential for interference. Project participant André Kesteloot, N4ICK, says the WA2XTF/12 beacon setup employs an "Earth bipole" style antenna that's grounded at both ends. The shorter leg consists of 100 feet of wire grounded to a 250-foot deep well casing. The longer leg is some 1500 feet of wire stretched horizontally about 20 feet above the ground, "strung from one tree to another, like a telegraph wire," Kesteloot says. The far end of the longer leg is connected to a rod inserted into a pond. He said two large coils were inserted in series with the longer wire--one at the transmitter end, the other near the pond end--to bring the antenna into resonance at 136.750 kHz. As AMRAD President (and ARRL Technical Relations Manager) Paul Rinaldo, W4RI, tells it, installation of the huge antenna earlier this fall was one of the more challenging aspects of the project. "When we got to the end of the run, we were greeted by more than 20 cows," he said. "At first, we were open to the thought that they were interested in Amateur Radio antenna experimentation. But the more likely story was that they thought it was feeding time." Kesteloot reports the WA2XTF/12 transmitter was fired up on November 14. AMRAD is seeking additional reports. Reception reports may be sent via e-mail to André Kesteloot, N4ICK, n4ick@amrad.org.

Also tried to 'break' some G's ragshewing with GI3PDN on sunday morning, but no succes. Maybe it would be a good idea to leave a 10 or 15 second gap during each 'over' while ragshewing, some nice DX might show up. One remark regarding GRAM : so far I was still using GRAM 4 and on sundaymoring I was 'playing' with GRAM 5. I had the audiogain of the RX far open, so the soundcard was 'clipping' when I saw David calling with a rather weak signal. When I reduced the audiolevel to about 1/4th of 'full scale' (as I used to do with GRAM 4) David's signal was gone and I had to increase the audiolevel again until it was close to 'clipping' before I got the signal back on screen. After our QSO I switched to GRAM 4 and could see David's next CQ without problems (perfect 'O', while the best I could give with GRAM 5 was 'M'). So, despite the many 'rings and bells' of GRAM 5 (or just because of this ?) a first comparison was in favour of GRAM 4. Or maybe I just have to optimize the parameters of GRAM 5. 73, Rik ON7YD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 27162 invoked from network); 20 Dec 1999 11:53:11 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by 212.159.2.35 with SMTP; 20 Dec 1999 11:53:11 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.02 #1) id 1201Qj-00088H-00 for rsgb_lf_group-outgoing@blacksheep.org; Mon, 20 Dec 1999 11:56:45 +0000 Received: from tungsten.btinternet.com ([194.73.73.81]) by post.thorcom.com with esmtp (Exim 3.02 #1) id 1201Qi-00088C-00 for rsgb_lf_group@blacksheep.org; Mon, 20 Dec 1999 11:56:44 +0000 Received: from [213.1.132.202] (helo=default) by tungsten.btinternet.com with smtp (Exim 2.05 #1) id 1200vW-000693-00 for rsgb_lf_group@blacksheep.org; Mon, 20 Dec 1999 11:24:31 +0000 Message-ID: <000a01bf4adc$71ca3100$ca8401d5@default> From: "Alan Melia" To: "rsgb_lf_group" Subject: LF: DX Cluster postings 18/19th Dec at GB7DXM Date: Mon, 20 Dec 1999 11:20:52 -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, few cluster spots this weekend and not very serious listening on my part.

Activity seemed to be a bit down this weekend, hope the weather is not causing too much havoc with your aerials. I suspect I got a lot more 50Hz wandering QRM from seasonal TV watchers than normal, punctuated by the occasional load 'raspberry' as an S9 carrier with wideband 100Hz mod swished across the band. These seem to 'park' outside the band most times now, just leaving a 'rumbling' background noise.

However, there are several others who are far below the noise level. If you have look on my homepage (http:/www.qru.de/signals.htm), you will see a graph, that shows the signal strenght in dBu vs. the distance in km. Most of the German stations for example suffer from both: low power (20 Watt due to the German regulations ... ) and bad antennas. The noise level at my qth typically is in the -110 dBu range, sometimes moch worse (-90 to -100 dBu): I had several contacts with stations on 136 kHz, that I could not hear aurally, because their signals were 10 to 20 db below the current noise level. With an "M", we still were able to manage a good QSO. Also on my page you find a list of stations that I have worked so far on LF (http://www.qru.de/stnhrd.htm). In the column "max . signal strength" you find several stations without a signal report. Most of those stations were far below the noise level, but readable in Slow-CW. For example, I would not have been able to contact IK5ZPV in normal CW. I made some experiement, injecting a signal generator into the normal day-to-day noise. With my 25+ years of CW experiencs, I believe I can hear CW signals well below the noise level. But with spectrogram in Slow-CW, I am able to see (and read) signals that are 10 to 20 dB the lowest level my ear is even able to detect the signal. Maybe it is a matter of the Spectrogram settings. I am sure, if we ever have a successful 2-way transatlantic QSO, it will be in Slow CW! Best 73 Geri, DK8KW (W1KW) homepage: http://www.qru.de "Longwave enthusiasts do it extremely slow!"

All the >activity that I have heard on this frequency is workable on normal speed >cw at my qth. And, the activity you didn't *hear* is not ;-) Seriously, the received noise power is proportional to the receiver bandwidth (assuming random noise). Most of the information energy of a typical QRSS CW signal is contained within a fraction of a Hz of bandwidth. I have been told that the equivalent bandwidth of the human ear (trained CW operator) is about 50 Hz, which means that 22 dB (7 watts instead of 1kW, for example!) can be gained from using Spectrogram running a 16K point FFT (about 1/3 Hz BW per FFT bin at 5513 Hz sampling frequency). In addition, a few more dB's can be gained by averaging FFT's. Unfortunately, averaging is not as effective as reducing the BW since the S/N is proportional to the square root of the number of averaged samples. For example, I got a solid copy of IK1ODO's qrss transmission on the Spectrogram screen while the signal was *totally* inaudible to my ear. I even tried to move the VFO up and down (I think a slowly varying tone is easier to detect by ear) but all I heard was noise... Marcos's CW was solid on the screen! 73, Johan, SM6LKM From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 4120 invoked from network); 21 Dec 1999 01:54:47 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by teachers.core.plus.net.uk with SMTP; 21 Dec 1999 01:54:47 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.02 #1) id 120Eo5-0004n5-00 for rsgb_lf_group-outgoing@blacksheep.org; Tue, 21 Dec 1999 02:13:45 +0000 Received: from imo24.mx.aol.com ([152.163.225.68]) by post.thorcom.com with esmtp (Exim 3.02 #1) id 120Eo4-0004mw-00 for rsgb_lf_group@blacksheep.org; Tue, 21 Dec 1999 02:13:44 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from G0MRF@aol.com by imo24.mx.aol.com (mail_out_v24.6.) id l.0.ca076980 (1883) for ; Mon, 20 Dec 1999 20:40:56 -0500 (EST) From: G0MRF@aol.com X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Message-ID: <0.ca076980.259034a7@aol.com> Date: Mon, 20 Dec 1999 20:40:55 EST Subject: Re: LF: qrss 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.i for Windows 95 sub 137 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: In a message dated 12/20/99 7:21:09 GMT Standard Time, malcolmg3kev@netscapeonline.co.uk writes: << Hi All.

Please enlighten me please. de Mal/G3KEV >> Hi Mal. Weak signal working is the main advantage of QRS and Spectrogram should offer a 10dB advantage over your normal rx performance. Another good example of a QSO that is only possible using QRS techniques would be one that takes place within an environment of QRM e.g. In the many areas of Europe where Loran is present or, as in my area, where I can operate between lines generated by 50Hz harmonics. FFT techniques are also used in weak signal moonbounce etc. There has been a lot written on various web sites, in the LF source book, on this reflector and indeed in Rad Com. But I'm sure you are aware of these things. That Northern sense of humour......This is a wind-up. Right?

It is a physical law that SNR is inverse proportional to bandwidth. Practical bandwidth for 'copy by ear' is 30 to 50Hz, with QRSS you can achieve a bandwidth below 1Hz. Last sunday I had a QRSS/DFCW QSO with G0MRF, his signal was completey inaudible. >I could understand the use of this mode on 20 khz and below because of a >possible bandwith consideration.

We have other limitations than the commercials, besides the legal 1W ERP limit a lot of us are rather limited regarding antenna dimensions (= antenna efficiency) and in a lot of countries there is also a TX output limit (20W in DL, 100W in OH, 400W in PA etc...). This limits the ERP of many stations to 100mW or less. >I have not seen any weak signals on qrss that I could not copy aurally.

I have an old Acer 486DX laptop with a 200MB disk drive and I would like to press it into service for use with Gram.

Thanks to all who sent me advice re spectrogram.I have now solved the problem and of course it turns out to be "finger trouble",but all the information  and advice was most valuable. I shall now be looking for qrss signals in order to check out my equipment,before venturing on to the nezt stage.One thing is that I can use my Racal 1792 Rx !
I am quite sure that we will need the additional sig/noise afforded by qrss if we are to achive a transatlantic QSO. I am reading IEE reports of long distance tests carried out in the late 1940s and will try to sort out some figures re signal strengths to be expected on this route. 73s Laurie.

Or, if one is attempting longer distance than the available power and antenna would normally be capable of reaching. Sometimes the obvious statement _is_ the best answer. Signal-to-noise versus bandwidth is more than a technicality, given the limitations that are just plain unavoidable in amateur LF work. One way and another, "poor antenna, low power and noisy QTH" describe life for nearly everyone who works LF bands; and there's only so much that can be done to improve any of those, especially in heavily populated areas. (One watt ERP is a pretty significant limit by itself, apart from the practical realities which make it unrealistic for most amateurs to achieve. On this side of the pond, where the limit is presently one watt DC input instead of ERP, anything that helps make contact is welcome!) > The same argument could be used for using qrss on all other radio > frequencies ie 160 and 80 metres but I am not aware that such techniques > are being used. With power limits on the order of hundreds of watts, vastly more efficient antennas, and significantly less QRN, there is much less need at those frequencies. However, given that QRP operation is a popular subset of amateur activity, it's entirely possible that we may see it tried on HF as well. > Commercial operators on LF and VLF have adopted the MSK and PSK > approach.They need speed to move the traffic and cannot spend several > hours on one QSO. Precisely why they erect huge masts, bury vast fortunes in copper, and pump hundreds of kilowatts into the whole system. Were we able (and permitted) to do the same, there would be no point in QRSS for us, either. > There is a possibility that qrss could be a lazy mans cw !!

Hi Geri. Qrss is discouraging experimenters from improving their antennas, receivers and associated equipment to make a normal aural qso. It is also encouraging nodding off (sleeping) during the hours that it takes to get a MMM.

If you are limited to 1 watt dc input it would be interested to know what your expectations are of crossing the Atlantic to the UK on qrss. I rate your chances as NIL, except you have an exceptional antenna system. Please give me more information and I will endevour to have a qso with you. The best that I can manage is a 120 ft tower with a comprehensive top loading system and and a good elevated radial system and 1 watt erp. One other station to contact is MM0ALM near Aberdeen in Scotland. He has two large towers each about 140 feet high and a good antenna system suspended between them plus an elaborate radial system, and could possible get 1 watt erp out. One other that would be closer to you is GI3OQR, he has two 150 feet towers separated by 500 yards and although he is not active on 136 has the capability to listen for you. Give me some details about your experiments. I will also be in Tyrone (N.Ireland), which is closer to the USA in February for 2 weeks and will try to work the USA preferably on normal cw but I also have qrss facilities. My antenna system there is also a 120 ft tower on a small farm similar to the Scarborough qth system. I could possible extend the height conveniently to 140 feet, giving me a little more advantage.

I rate your chances as NIL >> Until we have a full-fledged amateur allocation here, with an ERP limit rather than our DC input and antenna length restrictions, I agree wholeheartedly! Even then, credible predictions for received signal stength indicate it will be desirable to use extremely narrowband (consequently, slow) techniques with the best available antenna systems. The AMRAD group, working under terms of an experimental license that approximates terms of an actual ham allocation, are the only US amateurs who stand even a remote chance of crossing the Atlantic in the foreseeable future; but given the most optimistic QRN and QRM levels, even they will need to use one or more bandwidth reduction or signal averaging techniques, with a resulting reduction in communications speed. I do not see evidence that "Qrss is discouraging experimenters from improving their antennas, receivers and associated equipment to make a normal aural qso," as expressed in the response to Geri. Based on messages posted to this list, it appears normal speed Morse is alive and well. In addition, many of the same experimenters developing QRSS techniques are themselves quite successful with conventional aural QSOs. The question may be (to borrow words attributed to that great Dane, Hamlet) whether tis nobler of mind to limit oneself to copying by ear at normal speeds, and bear the burden of communicating over difficult paths on a sporadic basis; or to take up arms such as QRSS or coherent techniques, and by communicating slowly, do it more consistently. Philosophically, if communication speed were the basis for saying one mode is more worthwhile than another, high-speed teleprinters would be the order of the day. If live human sending and aural copy are added to the criteria, then voice modes are superior to Morse. I can speak faster than the best CW operator alive, and if allowed enough power, I can reach just as far. But I don't think anyone would succeed selling that argument to a die-hard code enthusiast, logically consistent though it may be. Removing both philosophical questions and personal taste from the equation, I don't think QRSS is any more or less meritorious than aural CW. It's simply different, and will find its place in the arsenal of well-equipped experimenters. 73, John KD4IDY From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 9605 invoked from network); 22 Dec 1999 06:32:37 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by grants.core.plus.net.uk with SMTP; 22 Dec 1999 06:32:37 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.02 #1) id 120fj1-00063O-00 for rsgb_lf_group-outgoing@blacksheep.org; Wed, 22 Dec 1999 06:58:19 +0000 Received: from mta01.talk21.com ([62.172.192.171] helo=t21mta01-app.talk21.com) by post.thorcom.com with esmtp (Exim 3.02 #1) id 120fj0-00063J-00 for rsgb_lf_group@blacksheep.org; Wed, 22 Dec 1999 06:58:18 +0000 Received: from dave ([213.1.51.225]) by t21mta01-app.talk21.com (InterMail vM.4.01.02.00 201-229-116) with SMTP id <19991222062806.LOFH1955.t21mta01-app.talk21.com@dave> for ; Wed, 22 Dec 1999 06:28:06 +0000 Message-ID: <000101bf4c45$69ec2000$e13301d5@dave> From: "Dave Sergeant" To: "rsgb_lf_group" Subject: LF: QRSS etc Date: Tue, 21 Dec 1999 21:41:36 -0000 MIME-Version: 1.0 Content-Type: text/plain; charset=Windows-1252; 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: >From Dave G3YMC I am also among a few other active operators who prefer normal CW, and view with a slight scepticism the claims made by QRS operators of the merits of that mode. However I accept that QRS in all its forms is now very much part of the 136 scene and very much liked by those who use it. Although I have no interest in getting active on QRS (even though it may have advantages with my very small plot) I do not despise those who do use the mode. Let us stop the bickering and get on with the real work of working stuff on the band, however we want to do it. Digital TV interference: I have no direct experience of digital set top boxes and IDTV's and their potential for causing interference. With the current trend to 'free' boxes linked to subscriptions there are unlikely to be any coming through my workshop in the forseeable future, and being one who has no interest whatsoever in either sport or films I am unlikely to aquire one myself. However I do have other contacts in the TV trade and receive various comments on the digital services. If I hear anything relevant to interference I will pass it on. Alan Melila mentions a 100Hz modulated carrier just outside the band. Perhaps he is hearing the 9th harmonic of the line timebase frequency (15.625kHz) on 140.625. This is not a digital TV related issue, but large and wide screen sets may radiate rather more due to the higher deflection powers. We all seem to be suffering however from various forms of swishing and unstable buzzing noises in band at present - perhaps they are from digital TV sources, but I would not have thought they would be any more susceptible to radiating noise than any other form of computer driven equipment. Please note also that the CE interference specifications do not cover any emissions below about 1MHz - and I recently read that there is talk about relaxing the specifications (because they are too difficult to test to).

Hello Mal, I am very sorry but I do not understand the reason of your anti-QRSS (or DFCW) campaign. First of all using exteme narrowband modes is only one way of improving the distance you can cover, next to improving antenna and equipement. So it will nit stop experimenters from trying to improve anything. Also you are overestimating the duration of a QRSS QSO, it can be done in about 30 minutes. Using DFCW, a standard QSO needs only about 10 minutes, to be honest I have heard a lot of "normal CW" QSO's on 136kHz where due to poor S/N the calls, reports etc. had to be repeated over and over again resulting in a QSO duration far longer than 10 minutes. In these cases the use of DFCW might even had speed up things. Finally, nobody is forced to use QRSS and/or DFCW. Those who are happy with normal CW only can do so. But those who want to experiment with new modes should not be treated as a kind of second class hams, calling QRSS 'lazy mans CW' is just not fair.

I worked nearly 40 stations during the past 50 weekends, which means, that I don't really mind if a Slow-CW QSO takes minutes, hours or even a day, its the fun that counts. I will try Rik's Diversity Slow-CW next year, not to save time but to try something new. I always enjoyed the Slow-CW signals slowly passing by on my screan, and even my kids (6 and 9 year old) try to identify the signals, as soon as they apprear on the screen, dot by dot, dash by dash. If I need a good communication link between here and, lets say, OH (my ODX QSO so far), I simply change to 80, 40 or 30m, I can operate all bands and normal CW up to 30 wpm, or RTTY, or PSK31, or SSTV, I have a 2-element beam antenna for 30m and a 3-element for 20m and up ... so working dx around the world is no problem ... but I still love LF, its slow, its difficult, its challenging, and its a place to relax, meet friendly ops and have a QSO besides other activities. That is MY reason, why I love Slow-CW ... and still have fun with normal CW-QSOs from time to time. Wishing you all a relaxed and peaceful Christmas, and a very happy, succesful new year with a lot of QSOs on LF in whatever mode YOU prefer.

To  ON7YD,
                  Many thanks  Rik for our  first two way  LF  qso this evening. It has taken a long time to finally happen, but I really enjoyed our contact. Your signal  started at  429 , went up to 529, but towards the end had dropped back to 429 again.
Thank you for the  539.

If anyone is planning a little home construction over the holiday period you may like to look at a FET marketed by RS Components as an alternative to the IRFP450. STW34NB20 RS catalogue number 313-2920. Voltage 500 V Current 34 Amps Power Diss 180 Watts Rds ON 0.08 Ohms Package TO247 as IRFP450 etc. Drain connected to tab. Price #2.78 + VAT in 1 off. A small test circuit using two of these in class D comfortably produces 350 Watts at 86% efficiency after the low pass filter. I've tested with supplies from 24 to 60V and with qrss. As the Rds on is less than a quarter of the IRFP450, the device may also be OK for lower Voltage operation. I've also recently purchased a supply of 3C85 toroids from Philips. As there was a minimum order charge I've bought some of the 58mm cores and some smaller 15 x 8 x 5.5mm (OD ID H) which are very useful for directional coupler elements. If a VSWR bridge is on your "to be built" list, and you need a core, let me know. 73 es a "bug free" y2k David G0MRF From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 12847 invoked from network); 25 Dec 1999 19:12:19 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by grants.core.plus.net.uk with SMTP; 25 Dec 1999 19:12:19 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.02 #1) id 121x2R-0007H8-00 for rsgb_lf_group-outgoing@blacksheep.org; Sat, 25 Dec 1999 19:39:39 +0000 Received: from smtp-out1.bellatlantic.net ([199.45.39.156]) by post.thorcom.com with esmtp (Exim 3.02 #1) id 121x2Q-0007H3-00 for rsgb_lf_group@blacksheep.org; Sat, 25 Dec 1999 19:39:38 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from bellatlantic.net (client-151-200-126-37.bellatlantic.net [151.200.126.37]) by smtp-out1.bellatlantic.net (8.9.1/8.9.1) with ESMTP id OAA16325; Sat, 25 Dec 1999 14:05:26 -0500 (EST) Message-ID: <38651610.A17DE5FB@bellatlantic.net> Date: Sat, 25 Dec 1999 14:08:00 -0500 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 From: "Andre' Kesteloot" X-Mailer: Mozilla 4.02 [en]C-DIAL (WinNT; U) MIME-Version: 1.0 To: "rsgb_lf_group" Cc: "lf-amrad" , "Mitch Powell VE3OT" , "Larry Kayser VA3LK" Subject: LF: AMRAD LF Beacon goes DX 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: LF Fans, Our WA2XTF/12 beacon, working into a 1600 ft horizontal antenna grounded at both ends, was heard in London, Ontario.

Radio Regulations (ITU) states (at least in my old copy) that "Administrations authorizing the use of frequencies below 9 kHz shall ensure that no harmful interference is caused thereby to the services to which the bands above 9kHz are allocated". In Norway, the Telecommunication law regulates all the electromagnetic spectrum (actually including signalling by a flash-light :-) , so at least over here it is regulated. --Magne / la1bfa From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 282 invoked from network); 26 Dec 1999 16:26:23 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by teachers.core.plus.net.uk with SMTP; 26 Dec 1999 16:26:23 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.02 #1) id 122Glr-0005A5-00 for rsgb_lf_group-outgoing@blacksheep.org; Sun, 26 Dec 1999 16:43:51 +0000 Received: from smtp-out1.bellatlantic.net ([199.45.39.156]) by post.thorcom.com with esmtp (Exim 3.02 #1) id 122Glq-0005A0-00 for rsgb_lf_group@blacksheep.org; Sun, 26 Dec 1999 16:43:50 +0000 Received: from bellatlantic.net (client-151-200-126-65.bellatlantic.net [151.200.126.65]) by smtp-out1.bellatlantic.net (8.9.1/8.9.1) with ESMTP id LAA13755; Sun, 26 Dec 1999 11:08:38 -0500 (EST) X-Priority: 3 X-MSMail-Priority: Normal Message-ID: <38663E07.F7B2D067@bellatlantic.net> Date: Sun, 26 Dec 1999 11:10:47 -0500 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 From: "Andre' Kesteloot" X-Mailer: Mozilla 4.02 [en]C-DIAL (WinNT; U) MIME-Version: 1.0 To: W3HMS@aol.com Cc: "lf-amrad" , "rsgb_lf_group" Subject: LF: LF...162 Khz France References: <0.c77a6212.2596e6f2@aol.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: Congratulations, John.

One needs to consult the regulations in one's home country. Over here, frequencies below 9 kHz are not regulated, but the ITU requirement is interpreted to mean harmonic energy appearing on frequencies above 9 kHz must be kept below field strength levels specified in other parts of our FCC's rules. This makes the sub-9 kHz region ideal here for earth dipole experiments, and even conventional antennas, but only if one takes adequate harmonic suppression measures. 73, John From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 21039 invoked from network); 26 Dec 1999 21:51:39 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by grants.core.plus.net.uk with SMTP; 26 Dec 1999 21:51:39 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.02 #1) id 122Ly0-0006qx-00 for rsgb_lf_group-outgoing@blacksheep.org; Sun, 26 Dec 1999 22:16:44 +0000 Received: from mail3.svr.pol.co.uk ([195.92.193.19]) by post.thorcom.com with esmtp (Exim 3.02 #1) id 122Lxy-0006qs-00 for rsgb_lf_group@blacksheep.org; Sun, 26 Dec 1999 22:16:43 +0000 Received: from modem-107.name37.dialup.pol.co.uk ([62.136.178.107] helo=lvm) by mail3.svr.pol.co.uk with smtp (Exim 3.12 #0) id 122LSf-00047N-00 for rsgb_lf_group@blacksheep.org; Sun, 26 Dec 1999 21:44:22 +0000 Message-ID: <000201bf4fea$575fc920$6bb2883e@lvm> From: "LAWRENCE MAYHEAD" To: "rsgb lf group" Subject: LF: Christer Re QSO.

First of all, a Merry Christmas to everyone (yes, there are 12 days in Christmas so it's still time). Before leaving for a long drive, my neighbour phoned me to ask if I had a CB set that he could borrow from me. I don't have this sort of apparatus in my archives, so I decided to lend him one of my mobile HF rigs (he is a careful person). However, the IC-706MKIIG didn't transmit on 27 MHz. A quick look at some ftp files on the Internet gave me the solution: unsolder that diode, reset the CPU and there you go. Back from travel, my neighbour told me that the unit performed flawlessly and that he had been very happy with it. I knew this already. However, when I fired up the transceiver, I flipped the VFO down on 136 kHz and accidentally pressed the PTT switch... It transmits! I tuned the main station's rig on the same frequency to confirm my discovery: I could hear myself speaking! The problem is that there isn't enough power coming out, since the internal power meter doesn't even give a sign of life. I don't have the schematics of the unit, neither do I have the characteristics of the output transistors. They're referenced Motorola SRF J7044 (two for HF/50 MHz, one for 144/430 MHz). I suppose that the output circuits are not designed for such frequencies. But what about the transistors? Does anyone have any specs about them? I've had a look on the Motorola Website, but this specific reference doesn't appear anywhere. Maybe I could use the transceiver as a driver for an amplifier, who knows? 73, Mark, F6JSZ From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 8494 invoked from network); 27 Dec 1999 14:04:59 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by bells.core.plus.net.uk with SMTP; 27 Dec 1999 14:04:59 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.02 #1) id 122b7q-0003NN-00 for rsgb_lf_group-outgoing@blacksheep.org; Mon, 27 Dec 1999 14:27:54 +0000 Received: from mail6.svr.pol.co.uk ([195.92.193.212]) by post.thorcom.com with esmtp (Exim 3.02 #1) id 122b7p-0003NI-00 for rsgb_lf_group@blacksheep.org; Mon, 27 Dec 1999 14:27:53 +0000 Received: from modem-29.postman.dialup.pol.co.uk ([62.136.108.157] helo=lvm) by mail6.svr.pol.co.uk with smtp (Exim 3.12 #0) id 122acZ-0005Lt-00 for rsgb_lf_group@blacksheep.org; Mon, 27 Dec 1999 13:55:37 +0000 Message-ID: <000201bf5072$057041c0$9d6c883e@lvm> From: "LAWRENCE MAYHEAD" To: "rsgb lf group" Subject: LF: QRS Date: Mon, 27 Dec 1999 13:49:51 -0000 MIME-Version: 1.0 Content-Type: text/html; charset=windows-1252 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: Content-transfer-encoding: 8bit

Andy has been very keen on low frequency operation for some time now. My first crossband QSO (my signal on 137kHz and listening on 80m) was on 14/3/98 after some e-mail exchange following a signal report of my 136 signals. I have also had a 73kHz/80m crossband QSO on 22/3/98, where Andy received my signals 539 on fast CW. This was the first QSO involving 73kHz outside the UK. The distance between us is 337.5km and may be a record for receiving fast CW on 73kHz. I have also had a crossband 136 QSO with Andy's 90 year old father, F8DB on 4/4/98 Andy's large loop receiver antenna setup has been included in the LF Chapter of the RSGB Communication Handbook (Receiver Amplifier and Loop Antenna for 136kHz). -- Regards, Peter, G3LDO =============== End of forwarded message =================== From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 24105 invoked from network); 27 Dec 1999 21:47:00 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by bells.core.plus.net.uk with SMTP; 27 Dec 1999 21:47:00 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.02 #1) id 122iKM-0005tD-00 for rsgb_lf_group-outgoing@blacksheep.org; Mon, 27 Dec 1999 22:09:18 +0000 Received: from smtp-rt-7.wanadoo.fr ([193.252.19.161] helo=embelia.wanadoo.fr) by post.thorcom.com with esmtp (Exim 3.02 #1) id 122iKL-0005t8-00 for rsgb_lf_group@blacksheep.org; Mon, 27 Dec 1999 22:09:17 +0000 Received: from amyris.wanadoo.fr (193.252.19.150) by embelia.wanadoo.fr; 27 Dec 1999 22:37:01 +0100 Received: from pii-350 (164.138.190.12) by amyris.wanadoo.fr; 27 Dec 1999 22:36:37 +0100 Message-ID: <006801bf50b2$746c0420$0cbe8aa4@pii-350> From: "f1tay" To: rsgb_lf_group@blacksheep.org Subject: LF: Re: CQ F6CNI KN Date: Mon, 27 Dec 1999 20:26:01 -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 4.72.3155.0 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: -----Message d'origine----- De : M & S À : rsgb_lf_group@blacksheep.org Date : lundi 27 décembre 1999 17:05 Objet : LF: CQ F6CNI KN >Does anybody have the e-mail of F6CNI, the "other" F-OM interested in LF transmission? > >Please reply to: > >sovergne@club-internet.fr > >TNX es happy new year 2000! > > Excused my message in french but my english is very bad !

This new 2000 edition has been continuously worked upon to give you the most up to date NDB information available. Its over 120 spiral-bound pages in DIN A4 format now contain data of more than 3500 active NDBs located in Europe, the Northern African countries, and the Near and Middle East. Many of the more frequently heard transatlantic NDBs have been included, as well as NDBs operating from offshore installations such as oil platforms. Moreover the handbook includes widely reported unidentified beacons and irregular call signs which originate from so-called "negative keying". One or the other NDB mystery may be solved with this information on hand. As a new feature the 2000 edition does now show the NDB modulation frequency as monitored by a network of active NDB DXers. The layout of the NDB data is well known from the previous edition: part 1 (the reference list) shows the entries sorted by alphabetical order of the call sign and lists the carrier frequency, the modulation frequency, the authority or company taking care of the NDB, name and location of the NDB, country in ITU code, geographical coordinates, distance and Great Circle bearing. Part 2 of the handbook is sorted in frequency order, and part 3 in country order. As a special benefit to the users of this handbook, the distance and Great Circle bearing have been computed for the individual listener's location. *Please* don't forget to specify the geographic coordinates of your listening post when ordering (recommended format to be used: degrees/minutes/seconds). Please let me know whether you prefer the distance shown either in kilometers or in miles. To give newcomers an easy start the handbook includes a table showing those NDBs that are nearest to your location. And for those that are unfamiliar with Morse code, a reference table is included. WHERE TO ORDER To get your copy please send your order and advance payment to the following address: Michael Oexner, Hainfelder Str. 1, D-76835 Roschbach, Germany. If you require more information about the publication and have access to e-mail you can also contact me at the following e-mail address: michael.oexner@spksuew.ron.de PRICE The price for the 2000 edition of the European NDB handbook is DM 40.- / £15 / EURO 20 / US-$ 25. This includes postage and packaging for European destinations. HOW TO PAY If you want to avoid the high costs incurred by purchasing International Money Orders or Eurocheques etc. you can always send your payment in the form of Pound notes (10 + 5) or Dollar bills. If you are using this method though do be sure to take the usual precautions of concealing them well inside your letter. If you prefer to use Eurocheques or IMOs though you can make them payable to the account number 100156926, BLZ 54850010, Sparkasse Landau. DELIVERY TIME All handbooks will be produced individually, so a production time of 2 weeks should be expected. vy 73 + gd DX, Michael RX: ICOM R71A, Sony ICF-SW7600G, W&G SPM-3 Antenna: Radio West 22.5" ferrite loop with amplifier, Wellbrook ALA 100, 20m longwire Location: Roschbach, Germany N 49°15' E 8°07' Member: CSDXC, DSWCI, EUNL, LWCA, MWC Editor of "The European NDB Handbook" e-mail: michael.oexner@spksuew.ron.de From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 7305 invoked from network); 31 Dec 1999 16:26:03 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by teachers.core.plus.net.uk with SMTP; 31 Dec 1999 16:26:03 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.02 #1) id 12453y-0007pA-00 for rsgb_lf_group-outgoing@blacksheep.org; Fri, 31 Dec 1999 16:38:02 +0000 Received: from mail04.hostcenter.com ([195.186.64.57]) by post.thorcom.com with smtp (Exim 3.02 #1) id 12453x-0007p5-00 for rsgb_lf_group@blacksheep.org; Fri, 31 Dec 1999 16:38:02 +0000 Received: from www303.hostcenter.com (195.186.64.84) by mail04.hostcenter.com (RS ver 1.0.53) with SMTP id 05521344 for ; Fri, 31 Dec 1999 11:03:51 -0500 (EST) X-Priority: 3 X-MSMail-Priority: Normal Message-ID: <386CE1DF.BB0B2C4B@phonakcom.ch> Date: Fri, 31 Dec 1999 18:03:27 +0100 From: =?iso-8859-1?Q?Toni_B=E4rtschi?= X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Organization: Phonak Communications AG X-Mailer: Mozilla 4.6 [de] (Win98; I) X-Accept-Language: de MIME-Version: 1.0 To: rsgb_lf_group@blacksheep.org Subject: LF: HB9ASB QRT Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 8bit X-Loop-Detect: 1 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: >>From HB9ASB, JN36pt Unfortunately I lost my LF-antenna in the storm and it is not to repair.
