It's higly higroscopic, moreover braider cords are like sponges. Now I use monofilament nylon rope, like fishing line, some 3 mm in diameter but it's impossible to knot, you must use steel clamps. For end insulator polycarbonate is not higroscopic and selfextinguish (correct?) it can be worked like metal and can be bended up to 90 degree using bending machine. You can test polycarbonate using a lighter, perspex and polystirene burns polycarbonate not. 73 de Claudio, IK2PII ---------------------------------------------------------------------- Claudio Pozzi http://www.qsl.net/ik2pii happy Linux user E-Mail: Claudio Pozzi Date: 31-Oct-02 Time: 17:57:09 This message was sent by XFMail ---------------------------------------------------------------------- From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 22563 invoked from network); 31 Oct 2002 21:48:32 -0000 Received: from marstons.services.quay.plus.net (212.159.14.223) by mailstore with SMTP; 31 Oct 2002 21:48:32 -0000 Received: (qmail 27648 invoked by uid 10001); 31 Oct 2002 22:52:06 -0000 Received: from post.thorcom.com (193.82.116.70) by marstons.services.quay.plus.net with SMTP; 31 Oct 2002 22:52:06 -0000 Received: from majordom by post.thorcom.com with local (Exim 4.10) id 187N9H-0000AR-00 for rsgb_lf_group-outgoing@blacksheep.org; Thu, 31 Oct 2002 21:46:43 +0000 Received: from [195.235.30.34] (helo=smtp.bankinter.es) by post.thorcom.com with esmtp (Exim 4.10) id 187N9H-0000AI-00 for rsgb_lf_group@blacksheep.org; Thu, 31 Oct 2002 21:46:43 +0000 Received: from BI57429bankinter (h024202.nexo.es [195.235.24.202]) by smtp.bankinter.es (8.9.2/8.9.2) with SMTP id WAA16633 for ; Thu, 31 Oct 2002 22:42:58 +0100 (MET) Message-ID: <002301c28126$72c8d560$ca18ebc3@BI57429bankinter> From: =?iso-8859-1?Q?Jos=E9_Manuel?= To: rsgb_lf_group@blacksheep.org References: <000201c27ee2$246c9640$ea3f7ad5@main> Date: Thu, 31 Oct 2002 22:40:40 +0100 MIME-Version: 1.0 X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 6.00.2600.0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 X-MIME-Autoconverted: from 8bit to quoted-printable by smtp.bankinter.es id WAA16633 Subject: LF: Re: SPM-12 & PS12 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Spam-Status: No, hits=-0.6 required=5.0tests=QUOTED_EMAIL_TEXT,REFERENCES,SPAM_PHRASE_01_02, USER_AGENT_OEversion=2.42 Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group ----- Original Message ----- From: "Alan Melia" To: "LF-Group" Sent: Tuesday, October 29, 2002 1:28 AM Subject: LF: SPM-12 & PS12 > Hi all, well done Tracey...that sounds like a very reasonable price.

Most recent Windows systems are set up to always run the sound card at 48 kHz, and to convert from/to other sample rates in software, even if the sound card is capable of running at the other rates! That's so that you can have multiple applications playing sound at the same time, even though they are playing data at different rates. Likewise, multiple apps can record the same source simultaneously at different rates (in theory, this is buggy on my machine). Sample rate conversion is processor intensive, so some control is provided, to allow the user to conserve compute power at the expense of quality. It's possible that your sample rate converter is not set to maximum quality, and this is resulting in aliasing artifacts of greater amplitude. The description below applies to my Win XP with SoundBlaster Live; yours may differ somewhat. Open Control Panel, then Sounds and Audio Devices. Select the Audio tab, and under Sound playback click Advanced. Select the Performance tab, and under Sample rate conversion quality, there is a slider. My system has three settings called Standard, Improved, and Best. IMO, they should be called Awful, Poor, and Mediocre. Another possibility would be for Jason to be capable of output at a higher sample rate. This would only slightly increase the compute power needed, which would probably still be less than what's required in receive mode. Sampling at 48 kHz (or 44.1 kHz if it makes the computation easier), you could put the output at 15 kHz or higher, which should ease filtering the image frequency. If it generated two tones in quadrature on the stereo outputs, then you could use an image reject mixer in the Tx, and very little additional filtering would be needed. 73, Stewart KK7KA > Aliasing certainly is significant in (fairly recent) sound cards - I > designed my Jason TX implementation to take audio from the sound card at > 5kHz, and mix/filter it up to 137kHz.

Corona tends to be quite small and erode >slowly. What I saw was a yellow arc some 8cm long, running the length of >both insulators. This is not the normal property of a good insulator. I had this kind of problem quite a bit when I first started using kw power levels - what happens is corona appears near sharp ends and corners of conductors first, and chars the surface of the insulator. The carbon that forms on the surface of the insulator is conductive and acts a a new site for corona to form and so tracks slowly along the surface. If you catch it in time, you can often see intricate branched patterns of burnt tracks on the surface of the plastic. If you watch it closely, you can see each track slowly extending with little whitish arcs dancing around at the ends of the tracks. But of course, this usually sets fire to the plastic at some point. Of course, glass or ceramic insulators won't burn, but will get eroded or cracked in time. For some reason, it seems to happen more when the surface is wet. I have seen it occur on pieces of damp wood that were near but not actually in contact with the antenna wire. As Alan said, fitting corona rings to the ends and corners in the antenna wire solved the problem. These are just stiff wire hoops about 100mm in diameter, which reduce the field gradient around the pointy ends, and suppress the formation of corona. I found a good corona warning was given by a VHF broadcast radio left on while operating on LF - if corona appears, lots of loud crackles and pops are heard.

When I tried this, I found a spurious output on 6.025kHz only about 20dB down on the desired 5kHz output. Changing the output frequency to 4.5kHz effectively eliminated the problem. Evidently anti-aliasing filtering is there, but not very sharp cut-off. I have observed significant aliasing effects also when using SpecLab in "software receiver" mode. As far as dynamic range goes, with the current receiver/sound card combinations used, it seems dynamic range is almost always limited by the RX IF/audio stages rather than the sound card. In conventional use of the RX, all unwanted signals are removed by the IF filters, so designing the IF/Audio section to have high dynamic range would be redundant. However, in our narrow band LF applications, unwanted signal rejection is performed in the PC, and IF/AF non-linearity will have a major effect. Effectively we are putting a high-gain, not particularly linear amplifier in front of the main selectivity of the receiver. There would be a lot of benefit in taking IF output from the receiver directly from the filter outputs, and mixing it down to audio with minimal additional gain sufficient to get the band noise above the noise floor of the sound card. I expect this would give a much more radical improvement than adding more resolution bits to the sound card ADC.

I use  insulators kindly supplied by Dick, PA0SE. These are serious
insulators some 150mm long (6 inches in old money) made of glazed ceramic.


I still have a dozen in stock.

Also five really big ones, 25cm long and a mass of 0.82 kilogram.
Also six ceramic spreaders, 23.5cm long and a mass of 0.130 kilogram.

The last two items can be seen here:
Insulators.jpg

All material  comes from the former Dutch GPO transmitting station Radio Kootwijk.

I will be happy to supply these items to anyone interested at the cost of shipment.
When there are more than one applicant from the UK I prefer to send a parcel to one address with the request to distribute the items from there.

In this case the ignition > source is the 'sharp' end of the wire, which is subject to corona discharge > (mini plamsa torch) when excited. I don't think it was corona. Corona tends to be quite small and erode slowly. What I saw was a yellow arc some 8cm long, running the length of both insulators. This is not the normal property of a good insulator. When used by Decca, these bits of transparent plastic are not in contact with the Litz wire. they hold the slotted triangles that hold the wire. Perhaps there is less need to make these good insulators. The triangles themselves are certainly good for RF. I use one as a stand-off to prevent the up-wire touching my mast in a high wind. They are brittle, however, and would not be suitable when pulling strain is involved. The really good bits from the Decca sites are definitely Perspex and are originally about 40cm long by about 5cm and some 40mm thick with a large hole at one end. I have chopped these into 10cm lengths for use on the antenna. The problem that Peter had with salt on his insulators is, I understand, also troubling the French railways after the storm.

While running the 72kHz transmission I noticed that the support insulator support cord near the loading coil had parted and the antenna was held only by the lead from the coil to the insulator. I found that the nylon cord had burned through. I switched off the transmitter and replace the coil with a length of copper wire to support the insulator. I use insulators kindly supplied by Dick, PA0SE. These are serious insulators some 150mm long (6 inches in old money) made of glazed ceramic. When I fired up the transmitter again there was a spluttering noise from the insulator with slight variations in antenna current. There were small dragons of sparks up to 40mm long snaking up and down the surface of the insulator, accompanied with puffs of steam (it was raining at the time). I think the problem is caused by salt, although it should have washed off - it had been raining all day. Since the storm the windows in the house are all coated with a salt layer. The wireless ops chore of cleaning the insulators, described in the Admiralty Handbook of Wireless Telegraphy, was necessary to remove dried salt. Obviously the same routine needs to be applied here. Many thanks for those who sent reports on the 72kHz transmission. I was using the three modules and was running just over 1kW to the antenna.

If someone knows an easy way to get started in USB programming, I'd like to try interfacing one of those PIC's with fast ADC and USB interface to a PC.
(For a dummy like me, who does not really love windoze programming)

What I have done recently is writing a firmware for a PIC12F675 which sends I/Q samples to the PC through the serial port. The sampling rate is *exactly* 2500 samples/second, if the PIC is clocked with *exactly* 10.000 MHz. Not really suited for a software defined radio, but good for narrow-band work, and you can clock it with your high-precision GPS-sync'd source !
If someone wants to have the assembly sourcecode, or like to connect this simple converter on his DOS/Windoze/Linux program, please ask. The serial data format is very simple (4-byte-frames, 115.2kBit/second, 1 start+ 8 data + 1 stopbit, so data can be received through "COM1" or "COM2" using standard routines. The PIC12F675 is very cheap (~1.5 Euros), and is available in DIL-8 case. It can be programmed with one of those "simple PIC programmers" ;-)

Yes please, I would like the PIC code.  I did something similar in the past using a 16C71 PIC with 8 bit A/D.  This sampled at 4kHz and formed I/Q samples at 1kHz output rate as follows for every 4 input samples :
I = S1 + S2 - S3 - S4
Q = S1 - S2 - S3 + S4
 
This is valid PROVIDED the audio is prefiltered to the range 750 - 1250 Hz only which is the case for most CW filters in rigs.  It worked OK, but Soundcards do a better job, provided someone else writes teh software for them ;-)

Hello Group,

If someone knows an easy way to get started in USB programming, I'd like to try interfacing one of those PIC's with fast ADC and USB interface to a PC.
(For a dummy like me, who does not really love windoze programming)

What I have done recently is writing a firmware for a PIC12F675 which sends I/Q samples to the PC through the serial port. The sampling rate is *exactly* 2500 samples/second, if the PIC is clocked with *exactly* 10.000 MHz. Not really suited for a software defined radio, but good for narrow-band work, and you can clock it with your high-precision GPS-sync'd source !
If someone wants to have the assembly sourcecode, or like to connect this simple converter on his DOS/Windoze/Linux program, please ask. The serial data format is very simple (4-byte-frames, 115.2kBit/second, 1 start+ 8 data + 1 stopbit, so data can be received through "COM1" or "COM2" using standard routines. The PIC12F675 is very cheap (~1.5 Euros), and is available in DIL-8 case. It can be programmed with one of those "simple PIC programmers" ;-)

Might it be that Perspex will burn if there is an ignition source. In this case the ignition source is the 'sharp' end of the wire, which is subject to corona discharge (mini plamsa torch) when excited. Would this be solved by soldering a corona ring at the high voltage end of any wires?? A brass "curtain ring (gosh I am showing my age again !!) or simply a circular loop of thick copper wire would probably do the trick. I think Jim found he needed to use these and certainly Ralph who is running the 166.5kHz beacon in W-land has set fire to several lengths of white waste pipe before fitting rings.

These were stood off from a metal spreader bar at the top of the mast. I insulated them by using some plastic (I assumed it to be Perspex/Plexiglass) rods from an old Decca loading coil. I have been using another type of ex-Decca Perspex as insulators for more than a year. When I finally got it all tuned up again - the new coil resonated differently from the old one - the antenna current rose with extra power, then suddenly fell. I investigated and found the "insulators" sparking across. I rapidly removed the RF, but the plastic caught fire and burnt for about 15 minutes, eventually disintegrating so the extra wires now hang down and wave in the wind. If anyone has these Decca bits - they are the square-section pieces with a slot in - beware they are not good insulators! The attached picture shows one of the stand-offs still on fire and the wire from the other one dangling. The good news is that after the fire the system was stable, so I am back on the air again.

And then go on to look at other USB driven test equipment modules. As far as I can see, there is a gap in the market for USB operated test equipment - at least there was when I was approached about this a couple of years ago by someone who knew the electronic test equipment business - but I declined to get involved. Programming Windoze, especially for USB, is far too complicated for a non-professional programmer such as myself who likes to keep things simple :-( The PIC16C745 and '765 have a USB core and could form the central controller for any USB peripheral provided it can be made fast enough, otherwise a gate array approach is needed.

But for obvious reasons I don't want messages from the reflector popping up all the time on this one; tried once and it got very annoying. The various security measures in place make it impossible to access my home account from this computer - and quite rightly so. (Official homeworkers, by the way, have special dial up accounts and secure links provided) Internet access is available but very restricted in its scope - no downloads of any description are possible, and even .PDF files can give problems sometimes, many sites are blocked for some obscure reason - and some dubious ones aren't ;-). This g4jnt account is my home one, but also accessed from another computer at work where I have a dial up modem, the other side of the office. Full Internet access is the 'official' justification for having this route. So it is easy enough to download and even post from it, BUT being a quarantined machine does not have any other software or network connections on it. The only way of transporting data between the two machines is floppy disc or, ironically enough, EMail. For the sake of completeness I usually copy messages to the other account. So that's the story, as far as my computer access is concerned, for those querying the reasons for posting from a non subscriber. AND I'd like to get rich quick too, anything to stop wasting 8 hours a day, five days a week just to earn the money to enjoy myself.

Or do employers there restrict their employees' Web access more tightly than is done here? 73, John From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 17032 invoked from network); 30 Oct 2002 03:12:50 -0000 Received: from marstons.services.quay.plus.net (212.159.14.223) by mailstore with SMTP; 30 Oct 2002 03:12:50 -0000 Received: (qmail 29214 invoked by uid 10001); 30 Oct 2002 04:15:54 -0000 X-MSMail-Priority: Normal Received: from post.thorcom.com (193.82.116.70) by marstons.services.quay.plus.net with SMTP; 30 Oct 2002 04:15:54 -0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from majordom by post.thorcom.com with local (Exim 4.10) id 186jG7-0002Jl-00 for rsgb_lf_group-outgoing@blacksheep.org; Wed, 30 Oct 2002 03:11:07 +0000 Received: from [24.153.64.2] (helo=smtp.comcast.net) by post.thorcom.com with esmtp (Exim 4.10) id 186jG6-0002JQ-00 for rsgb_lf_group@blacksheep.org; Wed, 30 Oct 2002 03:11:06 +0000 Received: from Charlie_Drake (pcp01445904pcs.lebnon01.pa.comcast.net [68.83.65.211]) by mtaout01.icomcast.net (iPlanet Messaging Server 5.1 HotFix 1.5 (built Sep 23 2002)) with SMTP id <0H4R005B2Y5JE3@mtaout01.icomcast.net> for rsgb_lf_group@blacksheep.org; Tue, 29 Oct 2002 22:10:35 -0500 (EST) Date: Tue, 29 Oct 2002 22:10:29 -0500 From: "Steve Dove" In-reply-to: <001001c27fa0$78e71420$4e60063e@main> To: "LF-Group" , rsgb_lf_group@blacksheep.org Message-ID: <41D0OJONTSSOPMDVQ86DBLI06YVRM3X.3dbf4da5@Charlie_Drake> Organization: d s p MIME-Version: 1.0 X-Mailer: Opera 6.04 build 1135 X-Priority: 3 Subject: Re: LF: sound cards...well amybe if.....

Simplistically, they're a single-bit convertor running at a few Megs the results of which are decimated down to 'standard' PCM; the initial alias is several MHz away and handily disposed of with a single RC LPF on the front. This is cause for dancing in the street, sorry! 106dB dynamic range doesn't mean much - the consumer audio world is still rife with 'creative specmanship' (remember the 500W 'music power' stereo amplifiers of old that were lucky to puff at 80W RMS?). The convertor set that Creative (!) are using is pretty middle-of-the-road in terms of performance - but there are some very good and very fast audio convertors around now: Although spec'd at around 120dB-ish dynamic range, they're measured 'A' weighted, in a sealed lead box, powered by car batteries, in a concrete bunker deep under the Rockies at the optimum Moon phase. Seriously, though, in the real world and measured honestly, around 110dB over a 20kHz bandwidth is doable through an A/D, D/A pair of chips today. Which is very good in anybody's terms. It is impossible today to buy anything other than a '24-bit' convertor for audio; one cannot take the number of bits to mean anything much, and especially not go all wobbly and wide-eyed at the 144dB range implied! The difference is between how many 'real' bits and how many 'marketing' bits a particular device exhibits. It can actually be quite depressing to terminate the front-end of an A/D and still see a LOT of low-end bits still wittering. Incidentally, the faster the convertors go, the worse their noise/linearity gets. The good news is that they are improving at a fair clip; they're unrecognizable from just ten years ago. Another unsung dirty secret is that although systems may sample and store at 96 or 192kHz, for the most part signal processing (EQ, compression etc.) is still done at 48kHz (i.e. band-limited to 20kHz-ish), simply because the suggestion of doubling or quadrupling the amount of DSP hardware makes sane men twitch. In short, the available convertors mentioned (110dB real DR, 96kHz and so 40kHz bandwidth) are available in USB 'pods' (can't remember the manufacturers off-hand) which gets them out of the 'orrible 'puter environment, with drivers that emulate 'Blasters. They are very popular in the computer-based music-studio world. The means already exists to do a *serious* convertor/dsp back-end for a software defined radio using off-the-shelf audio stuff; indeed, using older generation parts, this is just what Icom did in the 'PRO, with very creditable results. We have every reason to all get excited about all this!

The state of the art is several orders of magnitude better for both parameters. Take a look at this A/D with S/H: http://products.analog.com/products/info.asp?product=AD6645 . It can sample at up to 105 MHz, and with decimation, a.k.a. undersampling, works with band limited IF centered at up to 200 MHz. Clocking from the sound card is also no problem. Just tap its internal sample clock and divide by 256 (or other oversample factor). The phase will be arbitrary with respect to the output samples, but that should not matter. Better, remove the sound card's crystal and feed in your own stable main clock. But it is much easier to design these systems when you can set the sample rate to a value suitable for the input frequency. With a sound card, you may not have that option. Paul's example, with one A/D channel, would be unable to distinguish 143 kHz from 145 kHz; they would both produce a 1 kHz audio signal, since the third harmonic of 48 is 144. With stereo recording (using two S/H 90 degrees apart), you can reject the image, and ideal filtering would give you up to 48 kHz bandwidth, but maybe not the 48 kHz band you want. IMO, the linrad approach is much cleaner and will perform better. 73, Stewart KK7KA > On Tue, 29 Oct 2002 23:08:21 -0000, "Alan Melia" > wrote: > > >Hi Alberto, we are all jumping on you for your over-enthusiasm........but it > >occurs to me that this is a 24bit card....than may be more significant.

In this example, even 48 kHz ADC sample rate would be sufficient, but how do you control an external sample&hold circuit from a sound card ?

I offer that the era has already arrived. Take a good hard look at LINRAD. I drove all the way down to south eastern PA to visit Roger, W3SZ a few weeks ago. He has a highly optimized LINRAD system that does EME on 144 effortlessly with a simple receiver and seeing Roger tweaking the performance was a true experience for me. LINRAD of course does not do anything for the propagation workers curse of figuring out efficiently and quickly how to discard 98% to 99% of the data collected in an experiment. LINRAD does go a very long way towards being a critical part of the analysis tool box for examining data by ruthlessly tweaking for performance. LINRAD does require a heavy investment in learning how to tweak the system for high performance - I offer that anyone starting now MIGHT be ready by the time it is possible to use PC level products to do a direct receiver for 136 KHz, as you suggest this will come in the next year or so. I am sending this to rhe reflector in the hope that some discussion might follow on what the next generation of DSP software might look like. My needs continue to be to find a DSP engine that I can write application and human interface layers for in MS VB6 - these tools will be essential to make major steps forward in the world of recognizing and exploiting propagation events that occur infrequently to very rare occurrences.

See http://www.rmsinst.com/dt3.htm for a good introduction and http://www.innovative-dsp.com/products/sd.htm for a typical "pro" card. I don't know anything about the new Audigy, but would be very surprised if it used a different technology. The sigma-delta units internally oversample at 64 to 256 times the output sample rate, and use a sophisticated digital filter to eliminate aliases as well as reduce noise. The analog pre-filter, if any, only needs to attenuate in the MHz region. It's possible that the Audigy has programmable firmware for its digital filter, often hard-wired in silicon, but even then, it would be very difficult to modify, because you have no chance of getting the source code, development tools, etc. On the other hand, it should be possible to clock an external sample/hold circuit at 96 kHz, to recreate the desired alias response. Of course, you now need some decent analog bandpass filtering ahead of the S/H, to avoid *unwanted* aliasing. For example, 152 kHz (192 - 40) will also produce a 40 kHz output, and must be removed by the RF filter. The LW broadcasters on 153 kHz can be pretty strong... 73, Stewart KK7KA > Hi Alberto, we are all jumping on you for your over-enthusiasm........but it > occurs to me that this is a 24bit card....than may be more significant.

Pin 1 is earthy. As I suspected, the keying is upside down that is "make" generates a space and "break" generates a mark. Using a simple Basic program in an old NEC PC8201 (2MHz 80C85 ) the keying sounds OK at 15wpm.....about the maximum this little old thing (the computer not 'NYK ......though there isnt that much difference) will run at. It sounds quite crisp coupled into the receiver, with no signs of slurring. The internal soft keying seems to do all that one might do with a key click filter.

I would be interested.... if I had not already got a pair. I presume they have the optional 25Hz filter and the synchroniser. I used the PS-12 in locked mode to provide a reference signal when looking for ZL6QH (the counter is not accurate enough so it was measured externally to 0.1Hz with a calibrated counter) After several hours warm up, I left the system running through the night and I think the drift of the locked source was about 0.75Hz in 10 hours. The PS-12 will also 'key' via a 5-pin (270) DIN socket on the rear apron. This is supposed to be soft switching of the source for some of the S/N tests that one might want to do. I have not yet determined what the time constant employed is but it should be adequate for QRSS. Just one problem (once again not verified by experiment yet) but I believe from looking at the circuit that the keying will be "upside-down" i.e break for mark, and make for space. The locking of the PS-12 to the synchroniser in the SPM-12 is a lot easier than the SPM-3 / PS-3 combo where three 4mm plug leads ( or one of the special patch leads ) is required. As Dick says you just connect a BNC coax patch lead between the appropriate sockets on the rear panel of the two units. The PS-12 senses the connection and kills its internal free-running oscillator. You will need to do a calibration check if you are using the 25Hz filter to make sure the PS-12 is in the middle of the SPM-12 filter....there is a "twiddle" to correct this. As one might expect the leveling is excellent and good to 0.1dB so one can sweep through a filter and there is a DC output which is effectively the meter deviation which can be sent to a plotter or A/D. The output is linear so you will have to record the range (I am not sure, but there is probably an digital output of this) The pair can also be swept with the aid of a WZ-6 (if anyone comes across one) alternatively a sweep generator in the 14Mhz range will do almost the same job. The usual way of sweeping is to leave the SPM-12 on "wide-band", I believe. Nice toys....enjoy them if you can find the space..... they are not small !!

Many thanks to Jim, Alan and Stewart for their advice regarding testing FETs. >From this I find that you can test Decca Tx module FETs (IRF250s) in situ using a variable PSU with voltage and current control and indication. Disconnect the transformer wire from the gate but leave the protection diodes in place (BZX79C10s). Set the PSU voltage to 10 or 12 volts and the current limiting to (say) 0.5A. Connect the positive and negative leads from the PSU to the drain and source respectively. Touch the gate with your hand (best done with the blade of a small screwdriver). This causes an indication in the current reading. To get full current touch the positive lead (connected to the drain) with the other hand. This should cause the current to go to the max limit set on the PSU. Repeat for all other suspect FETs. Using this method I quickly located the faulty FETs.

Far more importantly, several professionals in the Radio Communications field have been given a short outline of some of the technical advances radio amateurs are making these days in an area of the spectrum mostly deserted by them many decades ago, rather than just sitting and chatting about the weather ("It are not raining in Tokyo also" - Tony Hancock, 196?)

A lot of these devices consist of several small fets (or smaller BJTs) in parallel on the chip. It is possible to have some of these go open (BJTs suffer breaks in their emitter metallisation due to electro-migration of the contact metal) Breaks in source, or emitter, paralleling track on the chip could mean that the unit could look ok at low currents, but be overloaded when run at full blast.

Dear Peter, LF Group, I have in the past found power MOSFETs can partially fail, where they appear to be working when simple go/no-go tests are applied, but quickly get hot and fail when put back in the circuit. so it is certainly a good idea to do the tests Alan and Stewart have suggested. In particular, pretty well no gate current should flow, so if you connect a clip lead to the gate to bias it on, then remove the lead without touching the gate, it should stay biased on for several seconds at least, probably minutes or more.. The "on" resistance of an IRF250 is 0.085ohms maximum (with 10V Vgs bias), so too small to measure with a multimeter - better to put a known current, say 1A, through it and measure the voltage drop between source and drain leads (should be below 85mV). Also check all the other components in the PA circuit - all the diodes and zeners, the driver transistor etc. When one component goes, it tends to take others with it. When you put it back together, with no "HT" supply check there are reasonably clean 136kHz square waves driving all 4 gates at about 15 - 20V pk-pk, symetrical around 0V. Start off running the module on a low "HT" voltage, say 5V (but don't reduce the driver supply voltage!!!) - the current drain should be down in proportion to the reduction in supply voltage with a class D amplifier. When you are sure it is working OK at low voltage, gradually increase to the full supply voltage, checking that things don't get hot. Starting off with a low supply greatly reduces the possibilities for blowing things up again.

I studied parliamentary english): Dear Uwe, this problem was thoroughly examined with the computation of resonance transformer switching PSUs. the characteristic impedance of a resonant circuit can correspond to the load resistance - but no less, otherwise no complete oscillation will come off, i.e. resonant circuit quality Q under full load no less than "one". if you want to take more pwr out of your resonant circuit whilst the supply voltage does not change, the internal resistance of the resonant circuit must be minimized. this is done by decreasing the inductivity and increasing the capacity. characteristic impedance = sqrt(L/C). this applies in particular if the control source, the PA circuit, has a high internal resistance, thus a pi formation for output circuit. for this a simplified diagram: at a generator with an internal resistance zero an inductance is connected to one terminal. in series with the inductance is a condenser, the other terminal of the condenser is connected to the other terminal of the generator. parallel to the condenser is the load resistance. the value of the inductance limits the short-cut-current of the generator. under no-load condition the voltage at the condenser rises nearly to infinite, only by the losses of the circuit limited. if thereby the inductance is magnetized to saturation, the voltage at the condenser in no-load condition is likewise limited, because the resonant circuit detunes. more you`ll find in the documents conc resonance transformer ICs at the company Unitrode (also Unitrode Integrated Circuits Corporation, now Texas Instruments, TI.Com). 55, Hans Albrecht DK 8 lp regards Uwe/dj8wx From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 12812 invoked from network); 27 Oct 2002 23:08:17 -0000 Received: from marstons.services.quay.plus.net (212.159.14.223) by mailstore with SMTP; 27 Oct 2002 23:08:17 -0000 Received: (qmail 16198 invoked by uid 10001); 28 Oct 2002 00:14:25 -0000 Received: from post.thorcom.com (193.82.116.70) by marstons.services.quay.plus.net with SMTP; 28 Oct 2002 00:14:25 -0000 Received: from majordom by post.thorcom.com with local (Exim 4.10) id 185wXK-0001fA-00 for rsgb_lf_group-outgoing@blacksheep.org; Sun, 27 Oct 2002 23:09:38 +0000 Received: from [165.254.158.18] (helo=mail.mcf.com) by post.thorcom.com with esmtp (Exim 4.10) id 185wXK-0001f1-00 for rsgb_lf_group@blacksheep.org; Sun, 27 Oct 2002 23:09:38 +0000 Received: from parissn2 (80.13.55.179) by mail.mcf.com with ESMTP (Eudora Internet Mail Server 3.1.4) for ; Sun, 27 Oct 2002 18:09:37 -0500 Message-ID: <001b01c27e0d$ee1c4560$0700000a@parissn2> From: "Stewart Nelson" To: rsgb_lf_group@blacksheep.org References: <001901c27e08$642b6980$e9847ad5@main> Date: Mon, 28 Oct 2002 00:09:40 +0100 MIME-Version: 1.0 X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 6.00.2720.3000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Subject: LF: Re: testing FETs Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Spam-Status: No, hits=0.5 required=5.0tests=REFERENCES,SPAM_PHRASE_00_01,USER_AGENT_OEversion=2.42 Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Hi Peter and all, Although a FET normally "blows" shorted, if the circuit that it is in permits a huge current to then flow, the internal bonding wire will act as a fuse and the final result is an open. With gate connected to source, measuring from source to drain you should see a diode (N-channel part will conduct when drain is negative). From gate to source there should be an open circuit with either polarity (at normal ohmmeter voltages). If both of these tests pass, the device is probably ok, because any abuse sufficient to blow the gate open would not leave the drain to source circuit intact. But, if you want to actually operate the device with just an ohmmeter... With gate open and measuring ohms from drain to source (drain positive), the static charge from e.g. a comb waved a couple of inches from the gate lead should turn the device on and off. Don't actually touch the gate with the charged object; the ESD might damage it, although high power devices are generally quite rugged. 73, Stewart KK7KA From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 31068 invoked from network); 27 Oct 2002 23:05:12 -0000 Received: from murphys.services.quay.plus.net (212.159.14.225) by mailstore with SMTP; 27 Oct 2002 23:05:12 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: (qmail 9620 invoked from network); 27 Oct 2002 23:03:47 -0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from post.thorcom.com (193.82.116.70) by murphys.services.quay.plus.net with SMTP; 27 Oct 2002 23:03:47 -0000 X-SQ: A Received: from majordom by post.thorcom.com with local (Exim 4.10) id 185wR7-0001cP-00 for rsgb_lf_group-outgoing@blacksheep.org; Sun, 27 Oct 2002 23:03:13 +0000 Received: from [152.163.225.104] (helo=imo-r08.mx.aol.com) by post.thorcom.com with esmtp (Exim 4.10) id 185wR7-0001aL-00 for rsgb_lf_group@blacksheep.org; Sun, 27 Oct 2002 23:03:13 +0000 Received: from MarkusVester@aol.com by imo-r08.mx.aol.com (mail_out_v34.13.) id l.47.252a3057 (4459) for ; Sun, 27 Oct 2002 18:02:39 -0500 (EST) From: MarkusVester@aol.com Message-ID: <47.252a3057.2aedca8e@aol.com> Date: Sun, 27 Oct 2002 18:02:38 EST To: rsgb_lf_group@blacksheep.org MIME-Version: 1.0 X-Mailer: AOL 7.0 for Windows DE sub 10501 Subject: Re: LF: storm Content-Type: text/html; charset=windows-1252 X-Spam-Status: No, hits=1.9 required=5.0tests=NO_REAL_NAME,SPAM_PHRASE_00_01,USER_AGENT_AOLversion=2.42 X-Spam-Level: * Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Content-transfer-encoding: 8bit Werner and Geri,

This is sufficient to turn-on a BJT but not sufficient to turn on a power FET of the type used in the Decca. The Audio FETs in the B&K may be different as they are used in linear audio applications.....they probably start to conduct at much lower gate source voltages. I suggest a little test rig with an ohm-meter across Drain-source (I dont think it matters which way round as the channel is resistive). Then use an external battery (PP3) or a PSU to put +9v through a 10k0 (series....i.e.current limit) resistor on the gate. Most of these power switching FETs take about 6 volts gate-source to switch on....hence no reading either way with an 'AVO'. The meter in d-s should be high resistance and swing to very low resistance when the 9v is applied to the gate..my IRF640s read about 2.6ohms on an Altai h/h DMM when on and fullscale when off. I think that any failure would mean that this sequence could not be repeated. I am not sure how they fail, but the aftermath of the initial fault could well be a ball of melted and recryatalised silicon. The high resistor in the gate lead should ensure that if the gate has broken down there will not be enough volts to switch the device on. A quick check could be made directly across g-s to show that all the 9v was being dropped across the 10k0 resistor. If the FET has suffered from over-current it will show resistance between d-s with no gate drive I think. Maybe those who have fryed fets will confirm.....I have not lost a single FET to my Class E experiments !!

But automatic or manual registration is not really pertinent to the issue of allowing NON-subscribers to post. This is a simple configuration setting in majordomo. I only vaguely remember the last discussion of why this is permitted, but it seems to me that one point did have something to do with people wanting to post messages while at work or otherwise away from their home Internet accounts. I can see the merit of one-way communication if one is away on a DXpedition and is temporarily using someone else's e-mail to report on operating schedules, for instance. But that is a rather rare use compared to the amount of spam lately. (There are also alternatives, such as sending e-mail to one of the regular members of the list and asking them to forward to it.)

This arrangement has served me well for the last 3 years. I use both of these methods, using a smooth metal hoop instead of a pulley, but it's the same principle. The secret is to avoid anything that gradually saws the rope. The springs on my antenna are bungee cords used for tying suitcases. Also, one of my masts is very springy. It all looks a bit frightening as it moves around in the wind, but so far it has stayed up. The bars that separate the three parallel top wires have been twisted, however. My neighbour has lost part of his fence and another has lost a tree. The town is strewn with fallen branches. Several local roads are partly blocked by fallen trees.

I only vaguely remember the last discussion of why this is permitted, but it seems to me that one point did have something to do with people wanting to post messages while at work or otherwise away from their home Internet accounts. I can see the merit of one-way communication if one is away on a DXpedition and is temporarily using someone else's e-mail to report on operating schedules, for instance. But that is a rather rare use compared to the amount of spam lately. (There are also alternatives, such as sending e-mail to one of the regular members of the list and asking them to forward to it.)

Where the rope going over the tree came to ground level, instead of tying it directly to an anchor point, it was fastened with a link of fairly thin wire which would take the tension normally, but break if the tree was thrashing around in a gale. This allowed several metres of rope to pay out and slacken the antenna wire. When the gale stopped, the rope was pulled tight again and the link replaced - this only happened a couple of times in a few years, and saved having to get the rope over the tree again.

Lieber Uwe, dieses Problem ist bei der Berechnung von Resonanzwandlerschaltnetzteilen gründlich untersucht worden. Der Kennwiderstand eines Schwingkreises darf minimal dem Lastwiderstand entsprechen, sonst kommt keine vollständige Schwingung mehr zustande, d. h. Schwingkreisgüte Q unter Vollast minimal 1. Wenn Du nun bei gleichbleibender Versorgungsspannung mehr Leistung aus Deinem Schwingkreis entnehmen willst, so muß der Innenwiderstand des Schwingkreises erniedrigt werden. Dies geschieht durch Erniedrigen der Induktivität und erhöhen der Kapazität. Kennwiderstand = sqrt(L/C) Dies gilt insbesondere dann, wenn die Steuerquelle, hier die PA-Schaltung, einen hohen Innenwiderstand hat, also ein PI-Filter im Ausgang. Hierzu eine vereinfachte Schaltung. Am Generator mit Innenwiderstand null ist am einen Pol eine Induktivität angeschlossen. In Reihe mit der Induktivität liegt ein Kondensator, der andere Pol des Kondensators liegt am anderen pol des Generators. Parallel zum Kondensator der Lastwiderstand. Der Wert dcer Induktivität begrenzt den Kurzschlußstrom des Generators. Im Leerlauf steigt die Spannung am Kondensator fast bis unendlich an, nur durch die Verluste des Kreises begrenzt. Wird die Induktivität dabei in die Sättigung magnetisiert, so wird ebenfalls die Spannung am Kondensator im Leerlauf begrenzt, da sich der Schwingkreis dann verstimmt. Mehr dazu findest Du in den Unterlagen über Resonanzwandler-ICs bei der Firma Unitrode, (auch Unitrode Integrated Circuits Corporation, inzwischen aber unter Texas Instruments, TI.Com). Soviel in aller Kürze. 55, Hans-Albrecht DK 8 ND > > regards and tks in advc > > Uwe/dj8wx > > > > > > > ________________________________________________________________ Keine verlorenen Lotto-Quittungen, keine vergessenen Gewinne mehr!

This arrangement has served me well for the last 3 years. I use both of these methods, using a smooth metal hoop instead of a pulley, but it's the same principle. The secret is to avoid anything that gradually saws the rope. The springs on my antenna are bungee cords used for tying suitcases. Also, one of my masts is very springy. It all looks a bit frightening as it moves around in the wind, but so far it has stayed up. The bars that separate the three parallel top wires have been twisted, however. My neighbour has lost part of his fence and another has lost a tree. The town is strewn with fallen branches. Several local roads are partly blocked by fallen trees. I may regret writing this as the wind is getting stronger again.

Normally I use a synthetic poly woven type diameter about 15 mm for guying towers in excess of 60 ft high. For tree work I use 10mm of the same type and do not have any problems. The trees are high beech and sycamore and fairly stable even at the 60-70 ft level but some movement in a gale condition. The marine variety rope is probably what you want. It is meant for a tough environment at sea. The ropes come in rolls usually 100/200 metres.With the heavier rope there is quite a sag be careful not to pull the tree over !!!! or the chimney off the house !! ------------ Regarding the odd spam appearing on the reflector it is easy enough to use the Delete key by the end user, the % is so small it is hardly worth getting too concerned about. Like junk mail I would rather do without it but I dont intend losing any sleep over it. 73 and hope you dont get blown away this weekend with the gales, not too bad up this way. de Mal/G3KEV > > > From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 21524 invoked from network); 27 Oct 2002 15:20:50 -0000 Received: from murphys.services.quay.plus.net (212.159.14.225) by mailstore with SMTP; 27 Oct 2002 15:20:50 -0000 Received: (qmail 22043 invoked from network); 27 Oct 2002 15:20:00 -0000 Received: from post.thorcom.com (193.82.116.70) by murphys.services.quay.plus.net with SMTP; 27 Oct 2002 15:20:00 -0000 X-SQ: A Received: from majordom by post.thorcom.com with local (Exim 4.10) id 185pCP-00083M-00 for rsgb_lf_group-outgoing@blacksheep.org; Sun, 27 Oct 2002 15:19:33 +0000 Received: from [62.253.164.45] (helo=mta5-svc.business.ntl.com) by post.thorcom.com with esmtp (Exim 4.10) id 185pCP-00083D-00 for rsgb_lf_group@blacksheep.org; Sun, 27 Oct 2002 15:19:33 +0000 Received: from l8p8y6 ([62.252.228.229]) by mta5-svc.business.ntl.com (InterMail vM.4.01.03.27 201-229-121-127-20010626) with SMTP id <20021027151932.ERC570.mta5-svc.business.ntl.com@l8p8y6> for ; Sun, 27 Oct 2002 15:19:32 +0000 Message-ID: <001701c27dcc$36bdbd40$e5e4fc3e@l8p8y6> From: "hamilton mal" To: rsgb_lf_group@blacksheep.org Date: Sun, 27 Oct 2002 14:44:16 -0000 MIME-Version: 1.0 X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.50.4807.1700 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Subject: LF: NEED Content-Type: text/html; charset=windows-1252 X-Spam-Status: No, hits=1.0 required=5.0tests=SPAM_PHRASE_00_01,USER_AGENT_OEversion=2.42 X-Spam-Level: * Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Content-transfer-encoding: 8bit

To support my HF long-wire, I have been using a similar arrangement here but, in addition, I have connected a spring "in series" with the pulley, to absorb small shocks. This arrangement has served me well for the last 3 years. 73 André From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 25373 invoked from network); 27 Oct 2002 13:11:43 -0000 Received: from murphys.services.quay.plus.net (212.159.14.225) by mailstore with SMTP; 27 Oct 2002 13:11:43 -0000 Received: (qmail 15589 invoked from network); 27 Oct 2002 13:11:12 -0000 Received: from post.thorcom.com (193.82.116.70) by murphys.services.quay.plus.net with SMTP; 27 Oct 2002 13:11:12 -0000 X-SQ: A Received: from majordom by post.thorcom.com with local (Exim 4.10) id 185n8O-0007nQ-00 for rsgb_lf_group-outgoing@blacksheep.org; Sun, 27 Oct 2002 13:07:16 +0000 Received: from [195.238.3.91] (helo=durendal.skynet.be) by post.thorcom.com with esmtp (Exim 4.10) id 185n8O-0007nH-00 for rsgb_lf_group@blacksheep.org; Sun, 27 Oct 2002 13:07:16 +0000 Received: from mh70i ([62.4.216.11]) by durendal.skynet.be (8.11.6/8.11.6/Skynet-OUT-2.20) with SMTP id g9RD7B016679 for ; Sun, 27 Oct 2002 14:07:11 +0100 (MET) (envelope-from ) Message-ID: <000b01c27db9$d59308c0$0bd8043e@mh70i> From: "DE BONDT WERNER" To: rsgb_lf_group@blacksheep.org Date: Sun, 27 Oct 2002 14:07:41 +0100 MIME-Version: 1.0 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 Subject: LF: storm Content-Type: text/html; charset=windows-1252 X-Spam-Status: No, hits=1.0 required=5.0tests=SPAM_PHRASE_00_01,USER_AGENT_OEversion=2.42 X-Spam-Level: * Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Content-transfer-encoding: 8bit

Hi all
After one year stby, I make a new vertical antenna with top hat and inductor.
11 m high (telescopic), diameter of hat 4m with a a spiral wire (57 m), top inductor : 50 uH.
resonate with 6mH (fix and vario).
This morning at 11:00 UTC on 137.69 KHz I saw I5TGC (-110db) and a qso (F6BWO - 110dB and  IK5ZTV - 100dB).
 
I can send pictures from reception and antenna (with webcam, low resolution!), just send me a mail.

IK5ZPV 136/qrs cq and with no response at this time, good signal 000/559.
 
Still nil hrd on 73 khz at my listening times, there used to be some big sigs audible some time back a year or so ago. Not encouraging for those hoping to get going on 73 khz.
Using a 73 khz resonant antenna here to a SPM12 rx, lots of commercial stns blowing my head off, but no amateurs.
 
Wx here so far good just a breeze blowing, with the odd light shower, no threat to antennas.

If removing spam from the reflector is easily done I would be in favour of it.  But I don't like forcing the sysop into a major operation.
And the delete key is always within easy reach of course...

It's a few months ago that we looked into this and I can't instantly recall

Unless I see postings opposing changes in the next two or three days I'll
discuss making configuration changes to reflector with the Sysop.

My own view is that I am so used to dealing with spam on my e-mail accounts
that removing it at source from this reflector doesn't make a significant
enough improvement to overcome the disadvantages of a re-configured
reflector.  However, I am quite content to go with the majority view!

Unless I see postings opposing changes in the next two or three days I'll discuss making configuration changes to reflector with the Sysop. My own view is that I am so used to dealing with spam on my e-mail accounts that removing it at source from this reflector doesn't make a significant enough improvement to overcome the disadvantages of a re-configured reflector. However, I am quite content to go with the majority view! 73 John, G3WKL > -----Original Message----- > From: owner-rsgb_lf_group@blacksheep.org > [mailto:owner-rsgb_lf_group@blacksheep.org]On Behalf Of WarmSpgs@aol.com > Sent: Friday, October 25, 2002 18:11 > To: rsgb_lf_group@blacksheep.org > Subject: Re: LF: Spam via reflector > > > In a message dated 10/25/02 4:33:10 AM Eastern Daylight Time, > dsergeant@connectfree.co.uk writes: > > << Perhaps the time has come to change this reflector into a > 'subscribers only can post' system.

Tie the two ends of the large rope together so you can pull the rope up with one side and pull it back down with the other side. Attach a pulley to this rope. Run your antenna support rope through the pulley and pull the pulley up with the big rope. Now pull your antenna up with the rope that goes through the pulley and tie a heavy weight to the antenna support rope. Now all the tree movement will just move the rope through the pulley and not cut the antenna support rope. I have this in my tree and I put a plastic drink glass over the pulley so the winter ice doesn't freeze the pulley. It has been up for two years now and there is no wear on either rope. 73's, Mike>WE0H http://www.we0h.us/lf.html -----Original Message----- From: owner-rsgb_lf_group@blacksheep.org [mailto:owner-rsgb_lf_group@blacksheep.org]On Behalf Of John W Gould Sent: Sunday, October 27, 2002 3:37 AM To: Rsgb_Lf_Group@Blacksheep.Org Subject: LF: Guy ropes Yet again the wind has taken my LF aerial down.

L (lf). Why You think "more power means less inductivity"? It's wrong! In general if pwr is changed the coupling betwin rf generator and antenna should be changed, not inductance. And coupling should be changed different way if pwr is increased by increasing of voltage or current. If You change pwr by simultaneosly increasing of voltage and current (constant output impedance) then You SOULD NOT readjast mutching equipment. 73 de RA9MB/Alex http://www.qsl.net/ra9mb From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 12999 invoked from network); 26 Oct 2002 18:02:32 -0000 Received: from warrior.services.quay.plus.net (212.159.14.227) by mailstore with SMTP; 26 Oct 2002 18:02:32 -0000 Received: (qmail 1461 invoked from network); 26 Oct 2002 18:03:55 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from post.thorcom.com (193.82.116.70) by warrior.services.quay.plus.net with SMTP; 26 Oct 2002 18:03:55 -0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from majordom by post.thorcom.com with local (Exim 4.10) id 185VHD-0004nk-00 for rsgb_lf_group-outgoing@blacksheep.org; Sat, 26 Oct 2002 19:03:11 +0100 Received: from [194.25.134.85] (helo=mailout11.sul.t-online.com) by post.thorcom.com with esmtp (Exim 4.10) id 185VHC-0004nb-00 for rsgb_lf_group@blacksheep.org; Sat, 26 Oct 2002 19:03:10 +0100 Received: from fwd07.sul.t-online.de by mailout11.sul.t-online.com with smtp id 185VH1-0000mr-07; Sat, 26 Oct 2002 20:02:59 +0200 Received: from (0482183881-0001@[62.224.50.93]) by fwd07.sul.t-online.com with smtp id 185VGt-1EYC8mC; Sat, 26 Oct 2002 20:02:51 +0200 From: "jannsen" <0482183881-0001@t-online.de> To: rsgb_lf_group@blacksheep.org References: <3DB90C79.13772.9C5650@localhost> <3DB9B489.7080905@usa.net> X-Mailer: T-Online eMail 2.34 MIME-Version: 1.0 Date: Sat, 26 Oct 2002 20:02:51 +0200 Message-ID: <185VGt-1EYC8mC@fwd07.sul.t-online.com> X-Sender: 0482183881-0001@t-dialin.net Subject: LF: vicious circle Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Spam-Status: No, hits=0.9 required=5.0tests=FROM_ENDS_IN_NUMS,FROM_STARTS_WITH_NUMS,REFERENCES, SPAM_PHRASE_00_01,USER_AGENT_TONLINEversion=2.42 Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Hi All, I have got a theoretical problem: if I considerably change the output pwr of any tx - sw or lf - I have to readjust the matching equipment. more pwr means less inductivity to readjust the resonance of the aerial if the aerial is a dipole (sw) or a inv. L (lf). but - more pwr the more capacity to readjust the resonance if I use the TX-loop (lf; 70m long, 12m up and 2m above ground, two windings). is it the charge caused by the E- or H-field "on the spot" (as ON7YD wld put it)? If so, why have I to increase the impedance in one case and to decrease it in the other? does the reader have an answer or does he know where I can look up the theorems? is there any theorem? regards and tks in advc Uwe/dj8wx From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 15275 invoked from network); 26 Oct 2002 17:43:01 -0000 Received: from warrior.services.quay.plus.net (212.159.14.227) by mailstore with SMTP; 26 Oct 2002 17:43:01 -0000 Received: (qmail 15246 invoked from network); 26 Oct 2002 17:42:15 -0000 Received: from post.thorcom.com (193.82.116.70) by warrior.services.quay.plus.net with SMTP; 26 Oct 2002 17:42:15 -0000 Received: from majordom by post.thorcom.com with local (Exim 4.10) id 185UvQ-0004jf-00 for rsgb_lf_group-outgoing@blacksheep.org; Sat, 26 Oct 2002 18:40:40 +0100 Received: from [62.253.164.42] (helo=mta2-svc.business.ntl.com) by post.thorcom.com with esmtp (Exim 4.10) id 185UvQ-0004jW-00 for rsgb_lf_group@blacksheep.org; Sat, 26 Oct 2002 18:40:40 +0100 Received: from l8p8y6 ([62.252.232.201]) by mta2-svc.business.ntl.com (InterMail vM.4.01.03.27 201-229-121-127-20010626) with SMTP id <20021026174039.RQOE3351.mta2-svc.business.ntl.com@l8p8y6> for ; Sat, 26 Oct 2002 18:40:39 +0100 Message-ID: <000c01c27d0e$6848a280$c9e8fc3e@l8p8y6> From: "hamilton mal" To: rsgb_lf_group@blacksheep.org Date: Sat, 26 Oct 2002 17:40:06 +0100 MIME-Version: 1.0 X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.50.4807.1700 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Subject: LF: 73khz Content-Type: text/html; charset=windows-1252 X-Spam-Status: No, hits=1.0 required=5.0tests=SPAM_PHRASE_00_01,SUPERLONG_LINE,USER_AGENT_OEversion=2.42 X-Spam-Level: * Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Content-transfer-encoding: 8bit

An interesting side effect of my 73kHz tests this weekend was that the stereo balance on my television went wrong and I had to unplug the set to reset the microprocessor. There's an awful lot of volts and I had to remake some antenna joints to reduce corona. Antenna survived a very stormy night. Even worse winds are forecast for Sunday.

I can get inside the bottom of the pole to put canes or somesuch inside - you describe external additions, is there a problem with putting something inside one of these poles? >The fishing pole is too good a support to ditch > completely and as you say has minimum visual impact. > I hope that gives you some ideas..... er where did you get the fishing pole > from and how much ?? Several ideas, thanks - I liked the pole enough to go and get another with the idea of guying it if all else failed (seems like a shame to have to do that). Having seen the info on G3CWI's site, I went to the local angling shop and asked what they had - they came out with these 5m poles at Ł7 ea., so I'm not too heartbroken at the failed experiment. When I asked about other lengths they shrugged and said it was pot luck what the wholesaler offered them.

I presume you were using "U" bolts ?? The rod is very strong but does not like being bent of a knife edge. Even thin gauge aluminium will buckle under the same circumstances. I always drive a piece of wood or a number of separate split canes up inside thinwall Al. tubes at the joint, and the base where the u-bolts go. I had a very cheap and cheerfull 10m 5/8ths that survived the 1987 "hurricane" because it was treated like that. You will need to stiffen it at the mounting so that the bending moment is spread over a longer length of the rod. (Fishermen bend these things almost double when they get excited !! but the "mounting" is very flexible, and the bending is spread over the length of the rod.) With your pole the stiffening will have to be on the outside. I dont know what the outer diameter is but plastic tubing offcuts of different diameters and tapered (in length) to stiffen the joint at the clamp but ensure that the stress is spread over a foot or so of rod. Another possibility is a "soft" mounting of compressed rubber "doughnut" ....you can sometimes get things like this as suspension bushes from a friendly helpful vehicle spares store...if you are lucky enough to know of such a place these days.....failing that some MOT failures might do the job. If you cant find a plastic tube to sheath it an length a snug fitting aluminium tube would be better, but split the top and jubilee clip it so that it can bend a little. Also moving the two support points further apart will allow it to bow between them more easing the strain.....chimnet and fascia mounts (abt 9in apart)are probably too close together for a long whip.. The fishing pole is too good a support to ditch completely and as you say has minimum visual impact. I hope that gives you some ideas..... er where did you get the fishing pole from and how much ??

It seems to me your antenna proposal is a hybrid of loop and vertical, with both voltage and current non-uniform - the current in the loop is non-uniform because some of the current returns to the feed point via "displacement currents" flowing in the distributed capacity of the antenna. In practice, this is true of any loop, since there is always a finite voltage difference between different points on the loop, and a finite distributed capacitance between them. The voltage on a practical monopole will not be equal at all points either, since there is always a finite distributed inductance which causes a potential difference when the antenna current flows through it. So all real antennas will have at least some hybrid electric/magnetic behavior - but what would be interesting to know is if exaggerating this would result in a useful efficiency improvement. As I understand it, whatever mode the antenna operates in, it is not possible to create an E field without an H field existing at the same time and vice versa, and also that feeding electrical energy into any generator of E/H fields will inevitably result in some energy propagating away as electromagnetic waves. The CFA people say that if E and H fields around the antenna are arranged to be in a certain relation that the efficiency of converting the incoming electrical energy into propagating e-m waves is greatly increased. I think conventional antenna theory would expect the net radiated signal from the antenna to be the superposition of the radiated signals produced by both electric and magnetic modes - So if the radiated signal was substantially different from the calculated level it would support the idea that existing antenna theory is wrong. Calculating what radiated signal this antenna should produce is another matter - to work out what was being radiated in each mode, you would need to measure the current distribution in different parts of the antenna - this ought to enable you to work out the effective height for the electric mode - since the current is non-uniform, you would also have to work out an "effective area" of the loop in magnetic mode.

My NOV says /P OK if you notify local RA a few days beforehand.



Just to clarify:  /P operation is not allowed on 73k band.

But-  As John suggests If you write or fax the RIS office in the area to be visited a few days in advance, then you can change the registered main station address to that of the proposed portable location.
Then you just set up at the location......which is now registered as your official address for whatever temporary period you have specified.

No need to use /P even if you are on a cliff top somewhere, as from the RAs perspective, that cliff top is now the main station address.

When I operated from GD, the local RIS office was in Belfast. It was the Bristol office who handled the application for the 73k operation from the HF convention a couple of years back and also for the 2 Daves and a Graham trip to GU.

I have a new loading coil made up from a Decca loading coil and made a outside shelter for the coil. I have had several QSOs and have been seen and heard by EA1PX. There is also an additional coil that sits on top of the Decca coil for 73kHz but this is not connected at the moment. Although I can work on 73kHz or 136kHz it takes me around an hour to change bands! My computer backup batteries used in the power supply are rather tired and these are being replaced by an odd selection of car batteries.

There could be problems of transients with the "synchronous switch" needed to make and break during each RF cycle. Most antennas work in "steady state mode" where the energy has time to reflect and establish a "standing wave pattern", and related wavefronts in space around the antenna. Your idea involves a rather interruptive action and would seem to reduce the scope for stored energy in near fields. 73, Bob 73, Bob From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 29256 invoked from network); 24 Oct 2002 21:33:34 -0000 Received: from marstons.services.quay.plus.net (212.159.14.223) by mailstore with SMTP; 24 Oct 2002 21:33:34 -0000 Received: (qmail 9410 invoked by uid 10001); 24 Oct 2002 22:39:24 -0000 Received: from post.thorcom.com (193.82.116.70) by marstons.services.quay.plus.net with SMTP; 24 Oct 2002 22:39:24 -0000 Received: from majordom by post.thorcom.com with local (Exim 4.10) id 184pcT-0007OK-00 for rsgb_lf_group-outgoing@blacksheep.org; Thu, 24 Oct 2002 22:34:21 +0100 Received: from [194.73.73.147] (helo=einsteinium) by post.thorcom.com with esmtp (Exim 4.10) id 184pcT-0007OB-00 for rsgb_lf_group@blacksheep.org; Thu, 24 Oct 2002 22:34:21 +0100 Received: from host217-39-21-209.in-addr.btopenworld.com ([217.39.21.209] helo=dellboy) by einsteinium with smtp (Exim 3.22 #11) id 184pcS-00066X-00 for rsgb_lf_group@blacksheep.org; Thu, 24 Oct 2002 22:34:20 +0100 Message-ID: <000801c27ba5$2f00d840$1700a8c0@home> From: "Dave Pick" To: rsgb_lf_group@blacksheep.org References: <001d01c27b84$8f3e00a0$316468d5@oemcomputer> Date: Thu, 24 Oct 2002 22:34:50 +0100 MIME-Version: 1.0 X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.50.4920.2300 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Subject: LF: Re: 73kHz Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Spam-Status: No, hits=-0.1 required=5.0tests=CALL_FREE,QUOTED_EMAIL_TEXT,REFERENCES,SPAM_PHRASE_00_01, USER_AGENT_OEversion=2.42 Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Mike, Laurie, Jim etc..

If antenna dimensions are an appreciable fraction of a wavelength, lumped reactances will start to affect the current distribution within a loop (or its variant, the line antenna) and thus affect its radiating properties. For an amateur-size loop, however, the current will be of the same magnitude and direction all the way around, even with the reactances present. In this design, it is true that there will be high voltages across the reactive components. But since it is accelerated units of charge which emit electromagnetic waves, merely having high electric fields present that contribute nothing to current in the antenna means only that there is increased risk of loss due to surrounding objects. And, it will be necessary to closely watch the Q of the coil, just as with a short vertical antenna. In a sense, such an antenna may represent the worst of both worlds (loop and monopole). Still, I don't mean to discourage anyone from trying. I think it speaks admirably for the human spirit that LowFERs strive to radiate useful signals from modest gardens, in the face of continual resistance from landlords, neighborhood associations, planning boards, and still higher forms of authority such as spouses. It can't be easy. 73, John From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 16798 invoked from network); 24 Oct 2002 17:42:00 -0000 Received: from marstons.services.quay.plus.net (212.159.14.223) by mailstore with SMTP; 24 Oct 2002 17:42:00 -0000 Received: (qmail 516 invoked by uid 10001); 24 Oct 2002 18:45:41 -0000 Received: from post.thorcom.com (193.82.116.70) by marstons.services.quay.plus.net with SMTP; 24 Oct 2002 18:45:41 -0000 Received: from majordom by post.thorcom.com with local (Exim 4.10) id 184lyL-0006yM-00 for rsgb_lf_group-outgoing@blacksheep.org; Thu, 24 Oct 2002 18:40:41 +0100 Received: from [62.253.162.47] (helo=mta07-svc.ntlworld.com) by post.thorcom.com with esmtp (Exim 4.10) id 184lyK-0006yD-00 for rsgb_lf_group@blacksheep.org; Thu, 24 Oct 2002 18:40:41 +0100 Received: from oemcomputer ([213.104.101.18]) by mta07-svc.ntlworld.com (InterMail vM.4.01.03.27 201-229-121-127-20010626) with SMTP id <20021024174035.CPWJ1554.mta07-svc.ntlworld.com@oemcomputer> for ; Thu, 24 Oct 2002 18:40:35 +0100 Message-ID: <001d01c27b84$8f3e00a0$316468d5@oemcomputer> From: "mike.dennison" To: rsgb_lf_group@blacksheep.org Date: Thu, 24 Oct 2002 18:41:09 +0100 MIME-Version: 1.0 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 Subject: LF: 73kHz Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Spam-Status: No, hits=1.2 required=5.0tests=CALL_FREE,SPAM_PHRASE_00_01,USER_AGENT_OEversion=2.42 X-Spam-Level: * Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group After spending all day winding coils, I am now QRV on 73kHz again.

Results; IC706, 3W o/p, 13.700MHz 30min on / 30 min off cycle for three hours. Maximum frequency excursion less than 70 mHz. TS850, 3W o/p, 13.700MHz ditto; Maximum frquency excursion less than 50 mHz. The Racal - Dana counter runs continuously, and both transceivers were run overnight to let them settle. The shack has thermostat controlled radiators but even so the temperature can walk about quite a bit so the test conditions were typical of normal operation.

An immediate thought - if the loop is big enough that you don't need the lumped loading L, then it's a single turn loop. If some of the L is packed in a wound component that doesn't radiate, then you lose (I'm guessing) according to the reduction in loop area, and by some function of the ratio of (inductance in the loop/inductance in the coil).

I seem to recall the RSGB HF committee handled applications for the NoVs on behalf of the RA - so they are probably the people to ask. The conditions for portable operation on 73k are that you have to inform the RA some time in advance of your /P location and other details of the operation - but this is just a formality.

Just heard your CQ on 71.75kHz with the aerial system tuned to 136kHz. Readibility 4. Signal strength is a bit difficult to measure under these circumstances but by ear I would put it at S4.

A crossband QSO 70/136kHz would be possible but we have done that before a couple of times already.

A good 559 here with the antenna off-resonance. I have reinstated my BK 200 watt amplifier and have the RF, but can't find enough good loading coils to get me below 90kHz! With a top section only 16m long it needs more than 12mH for resonance. Will wind another coil today and add it to the chain. Hope to be on air tomorrow morning but will e-mail you first. 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 9160 invoked from network); 24 Oct 2002 06:55:54 -0000 Received: from marstons.services.quay.plus.net (212.159.14.223) by mailstore with SMTP; 24 Oct 2002 06:55:54 -0000 Received: (qmail 8532 invoked by uid 10001); 24 Oct 2002 08:01:52 -0000 Received: from post.thorcom.com (193.82.116.70) by marstons.services.quay.plus.net with SMTP; 24 Oct 2002 08:01:52 -0000 Received: from majordom by post.thorcom.com with local (Exim 4.10) id 184bvF-0004z6-00 for rsgb_lf_group-outgoing@blacksheep.org; Thu, 24 Oct 2002 07:56:49 +0100 Received: from [212.1.130.1] (helo=smtp-1.visp.telinco.net) by post.thorcom.com with esmtp (Exim 4.10) id 184bvF-0004yx-00 for rsgb_lf_group@blacksheep.org; Thu, 24 Oct 2002 07:56:49 +0100 Received: from [212.1.140.191] (helo=pcuser) by smtp-1.visp.telinco.net with smtp (Exim 3.32 #1) id 184bqN-000572-00 for rsgb_lf_group@blacksheep.org; Thu, 24 Oct 2002 07:51:47 +0100 Message-ID: <000d01c27b2a$856dbe80$a28e01d4@pcuser> From: "Hugh Burnham" To: rsgb_lf_group@blacksheep.org References: <000b01c27ae2$989cb6c0$d17b7ad5@main> Date: Thu, 24 Oct 2002 07:56:07 +0100 MIME-Version: 1.0 X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.00.2919.6600 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Subject: LF: Re: 73k NoVs Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Spam-Status: No, hits=0.0 required=5.0tests=QUOTED_EMAIL_TEXT,REFERENCES,SPAM_PHRASE_03_05, USER_AGENT_OEversion=2.42 Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Hi Alan, Thankyou for your comments.

I have not checked the web sites yet but will do so in the next day or so. One or two related comments : Argo assisted reception of my 180 kHz CW signal shows a slight frequency shift on long "dots". However, the divide by 100 gives the obvious reduction from the drift measured at 18 MHz. I attempted to locate an ICOM TCXO unit but was told that they were no longer available. As suggested, the problem is a thermal one. Like Mal, I run the 706 at the 1-2 Watt level,into a dummy load, before the divider chain. At this power level the exercise is an extremely inefficient one - about 30 Watts has to be removed from the little black box ! Some tests at higher power levels did not improve the situation. To date, I have been keying the 706. This encourages plenty of fan cycling and internal temperature change. As an experiment, I intend to leave the transmitter turned on and key a later stage in the chain. Hopefully, this will keep the fan operating all of the time and improve the frequency stability a bit. Again, as suggested by Mike, I may have to further encourage the fan to run continuously. I had a look under the appropriate cover in the hope of packing some polystyrene or similar material around the crystal osc. However, there appeared to be a decided lack of surplus space. Again, my thanks to all who so willingly responded to my inquiry. 73, Kevin, ZL4MD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 17503 invoked from network); 22 Oct 2002 19:52:22 -0000 Received: from marstons.services.quay.plus.net (212.159.14.223) by mailstore with SMTP; 22 Oct 2002 19:52:22 -0000 Received: (qmail 4891 invoked by uid 10001); 22 Oct 2002 20:56:05 -0000 Received: from post.thorcom.com (193.82.116.70) by marstons.services.quay.plus.net with SMTP; 22 Oct 2002 20:56:05 -0000 Received: from majordom by post.thorcom.com with local (Exim 4.10) id 18453Q-0000LB-00 for rsgb_lf_group-outgoing@blacksheep.org; Tue, 22 Oct 2002 20:51:04 +0100 Received: from [210.86.15.146] (helo=mta203-rme.xtra.co.nz) by post.thorcom.com with esmtp (Exim 4.10) id 18453P-0000L2-00 for rsgb_lf_group@blacksheep.org; Tue, 22 Oct 2002 20:51:03 +0100 Received: from mta5-rme.xtra.co.nz ([210.86.15.142]) by mta203-rme.xtra.co.nz with ESMTP id <20021022195029.KFIE3817.mta203-rme.xtra.co.nz@mta5-rme.xtra.co.nz> for ; Wed, 23 Oct 2002 08:50:29 +1300 Received: from xtr743187 ([219.88.42.205]) by mta5-rme.xtra.co.nz with SMTP id <20021022195028.BGXK18266.mta5-rme.xtra.co.nz@xtr743187> for ; Wed, 23 Oct 2002 08:50:28 +1300 Message-ID: <002901c27a04$47aa5bc0$cd2a58db@xtr743187> From: "Vernall" To: rsgb_lf_group@blacksheep.org References: <3DB0C203.A90691A6@verizon.net> <000801c279ad$b339adc0$f530f7c2@a7j7r2> <3DB55E79.50901@usa.net> Date: Wed, 23 Oct 2002 08:49:39 +1300 MIME-Version: 1.0 X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.00.2919.6600 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Subject: LF: Type of IF filter Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Spam-Status: No, hits=-0.3 required=5.0tests=QUOTED_EMAIL_TEXT,REFERENCES,SPAM_PHRASE_00_01, USER_AGENT_OEversion=2.42 Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Hi all, Alberto commented: > IMHO, the main reason for the more pleasant sound is the IF > filter...supposing the '60s receiver > uses a crystal filter, while the Hallicrafters not. > Crystal filters are wonderful in the frequency domain, but terrible > performer in the time domain, > while LC filter just the opposite... My opinion as well. The issue is in "peaks" of group delay for frequencies just inside the edges of the steep roll-off of a filter. Crystal filters have a "squarer" shape factor, hence more peakier group delay (differential phase shift) characteristic. Some professional receivers have "equalising networks" to compensate the group delay over the desired passband. It is a difficult ask to measure group delay of filters, and to explore why the subjective result (by ear) of some filters is less pleasing than from others. It also has implications for data quality of digital modes, and how "equalisation" may be possible. Last weekend I discussed this with a friend who is familiar with PC sound card software, and Windoze operation, and he is confident he can develop an audio frequency response and group delay test set using a full duplex sound card. The basic line-up to investigate is: audio sweep is generated on an output, and the received version is input to the same sound card. The desire is to display graphs of frequency response and group delay, one above the other. This would allow for tweaking of filter tuning in real time, and saving files of results, or hardcopy capture. Such a test set could obviously test audio filters, including DSP filters. It could also deal with radio IF filters by using an SSB transmitter to convert the sweep to RF, and the test receiver in a BFO mode to downconvert to audio, near the original audio frequency. Applying a steady tone at setup may be sufficient for the sound card to find and correct for a frequency offset, as well as find the delay at that frequency (as a reference for sweeping other frequencies). Anyway, that is an outline of a potentially useful tool using a PC sound card. If and when software is developed and proven, I will advise where it could be downloaded from. The above description may also be a challenge for another developer to have a go. 73, Bob ZL2CA From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 12971 invoked from network); 22 Oct 2002 18:58:53 -0000 Received: from marstons.services.quay.plus.net (212.159.14.223) by mailstore with SMTP; 22 Oct 2002 18:58:53 -0000 Received: (qmail 2138 invoked by uid 10001); 22 Oct 2002 20:02:51 -0000 Received: from post.thorcom.com (193.82.116.70) by marstons.services.quay.plus.net with SMTP; 22 Oct 2002 20:02:51 -0000 Received: from majordom by post.thorcom.com with local (Exim 4.10) id 1844DT-00008n-00 for rsgb_lf_group-outgoing@blacksheep.org; Tue, 22 Oct 2002 19:57:23 +0100 Received: from [194.73.73.92] (helo=carbon.btinternet.com) by post.thorcom.com with esmtp (Exim 4.10) id 1844DT-00008c-00 for rsgb_lf_group@blacksheep.org; Tue, 22 Oct 2002 19:57:23 +0100 Received: from host217-35-32-71.in-addr.btopenworld.com ([217.35.32.71] helo=dellboy) by carbon.btinternet.com with smtp (Exim 3.22 #8) id 1844DR-0005Vo-00 for rsgb_lf_group@blacksheep.org; Tue, 22 Oct 2002 19:57:21 +0100 Message-ID: <005001c279fc$f1381860$1700a8c0@home> From: "Dave Pick" To: rsgb_lf_group@blacksheep.org References: <7D653C9C42F5D411A27C00508BF8803DCB9C55@mail.dstl.gov.uk> <3DB57FA7.8030504@virgin.net> Date: Tue, 22 Oct 2002 19:57:59 +0100 MIME-Version: 1.0 X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.50.4920.2300 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Subject: Re: LF: Jason versions and DDS COntroller Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Spam-Status: No, hits=0.5 required=5.0tests=REFERENCES,SPAM_PHRASE_00_01,USER_AGENT_OEversion=2.42 Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Stewart > I was wondering if it would be worth sacrificing the > bandwidth for the increased convenience of signal > generation? > The problem is Loran.

It seems to me that one of the difficulties is building the transmitter, which either requires a controlled DDS, or a mixer arrangement of some sort. A more convenient method would be to make the software program a conventional HF tx thriugh its CAT interface and use the divide by 100 method to generate 136KHz output. Unfortunately it is common for transmitter to be limited to a resolution of 10Hz, which ultimately leads to a resolution of 10mHz reather than the 1mHz that Jason calls for. I was wondering if it would be worth sacrificing the bandwidth for the increased convenience of signal generation? 73 Stewart G3YSX From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 23678 invoked from network); 22 Oct 2002 16:03:36 -0000 Received: from warrior.services.quay.plus.net (212.159.14.227) by mailstore with SMTP; 22 Oct 2002 16:03:36 -0000 Received: (qmail 1242 invoked from network); 22 Oct 2002 16:00:59 -0000 Received: from post.thorcom.com (193.82.116.70) by warrior.services.quay.plus.net with SMTP; 22 Oct 2002 16:00:59 -0000 Received: from majordom by post.thorcom.com with local (Exim 4.10) id 1841P8-0007zH-00 for rsgb_lf_group-outgoing@blacksheep.org; Tue, 22 Oct 2002 16:57:14 +0100 Received: from [195.92.195.172] (helo=cmailg2.svr.pol.co.uk) by post.thorcom.com with esmtp (Exim 4.10) id 1841P7-0007z8-00 for rsgb_lf_group@blacksheep.org; Tue, 22 Oct 2002 16:57:14 +0100 Received: from modem-50.oregon.dialup.pol.co.uk ([62.137.88.50] helo=f3a3a2) by cmailg2.svr.pol.co.uk with smtp (Exim 3.35 #1) id 1841P7-0001HM-00 for rsgb_lf_group@blacksheep.org; Tue, 22 Oct 2002 16:57:13 +0100 Message-ID: <001d01c279e4$c298e6a0$ea00a8c0@f3a3a2> From: "Laurie Mayhead" To: rsgb_lf_group@blacksheep.org Date: Tue, 22 Oct 2002 17:03:26 +0100 MIME-Version: 1.0 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 Subject: LF: 73kHz activity Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Spam-Status: No, hits=1.0 required=5.0tests=SPAM_PHRASE_00_01,USER_AGENT_OEversion=2.42 X-Spam-Level: * Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Got a bit of Ant. problem, so no 73 transmission tomorrow Wednesday. 73s Laurie.

I was awaiting to receive a bit more feedbacks. If you want to test it, please download http://www.weaksignals.com/bin/jaspak_v095a_test.exe It has both 9600 and 19200 bps as serial speeds, together with the infamous Hendrixizer and the Hard Clipper (to be ideally compared to see whether one of them can be discarded).

The conclusion, therefore, (and for those not having the time to study this) is that at least a moderate loss of signal signal occurs when a typical set of radials are drooped more than 20deg from the horizontal, right? I'm not sure I buy the "shielding effect" that the drooping radials impose, but I suppose the 'canceling effect' due to the reversal in current is one way to look at how a shield works.

In order to find  the effect of drooping top load wires upon the radiation resistance I modelled an umbrella antenna using K6STI's antenna simulation program Antenna Optimizer.

The antenna modelled consists of a vertical wire of 10 m with at the top four wires of 10 m each in the directions N, E, S and W.  The wires include an angle of alpha degrees with the horizontal.  All wires have a diameter of 1.5 millimetres.  The antenna is erected over perfect ground.

I spoke to one of the experts at BT Labs, who suggested that the output transformer might have something to do with it. Also, the characteristics of a bipolar transistor audio output stage are _not_ identical to those of a pentode or beam tetrode. 73, John Rabson G3PAI From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 28545 invoked from network); 22 Oct 2002 09:02:02 -0000 Content-Transfer-Encoding: 8bit Received: from murphys.services.quay.plus.net (212.159.14.225) by mailstore with SMTP; 22 Oct 2002 09:02:02 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: (qmail 6956 invoked from network); 22 Oct 2002 09:01:17 -0000 Received: from post.thorcom.com (193.82.116.70) by murphys.services.quay.plus.net with SMTP; 22 Oct 2002 09:01:17 -0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 X-SQ: A Received: from majordom by post.thorcom.com with local (Exim 4.10) id 183utB-0006c4-00 for rsgb_lf_group-outgoing@blacksheep.org; Tue, 22 Oct 2002 09:59:49 +0100 Received: from [192.5.29.49] (helo=relay.dstl.gov.uk) by post.thorcom.com with smtp (Exim 4.10) id 183utA-0006bv-00 for rsgb_lf_group@blacksheep.org; Tue, 22 Oct 2002 09:59:48 +0100 Received: (qmail 19328 invoked from network); 22 Oct 2002 09:59:44 +0100 Received: from warlock.dstl.gov.uk (192.5.29.10) by relay.dera.gov.uk with SMTP; 22 Oct 2002 09:59:44 +0100 Message-ID: <7D653C9C42F5D411A27C00508BF8803DCB9C55@mail.dstl.gov.uk> From: "Talbot Andrew" To: "LF Group \(E-mail\)" Date: Tue, 22 Oct 2002 09:59:22 +0100 MIME-Version: 1.0 X-Mailer: Internet Mail Service (5.5.2653.19) Subject: LF: Jason versions and DDS COntroller Content-Type: text/plain; charset=iso-8859-1; format=flowed X-Spam-Status: No, hits=1.0 required=5.0tests=EXCHANGE_SERVER,SPAM_PHRASE_03_05version=2.42 X-Spam-Level: * Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group I've rather lost track of Jason to date, currently using v0.94. I believe Alberto was intending to offer a 19200 baud serial link option in a future upgrade. Currently I have a version of my DDS controller that can accept Jason coded commands for setting the transmit frequency, at 9600 baud, but this has just about filled up the PIC memory leaving little scope for any further changes. If the Jason code were changed to allow 19200 baud, the same as my normal controller rate, all the RS232 routines in the PIC could be reused, freeing up some memory for later enhancements. Ideally, options of both 9600 and 19200 would allow for backwards compatibility. Andy G4JNT "This e-mail is intended for the recipient only.

I have an LF antenna that uses a telescopic mast for one part of multiple top loading (three masts in all). The mast is parked in the down position, and cranked up for LF transmitting. The far field is definitely lower (from S meter reports of several others) when the wire is below the "full" height. The situation may well depend on how good the ground conductivity is, as a "drooping" part of top loading means higher field strength to ground over the droopy part, and higher field strength means higher ground current and consequent I squared R losses. In other words, RF warm spots can arise under drooping wires. If the antenna is built over an immaculate ground system with hundreds of ground radials (as per a text book design), then the likes of an umbrella antenna would not be as lossy as one built over average soil with perhaps a few radials. 73, Bob ZL2CA From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 11407 invoked from network); 21 Oct 2002 19:41:10 -0000 Received: from marstons.services.quay.plus.net (212.159.14.223) by mailstore with SMTP; 21 Oct 2002 19:41:10 -0000 Received: (qmail 12170 invoked by uid 10001); 21 Oct 2002 20:47:01 -0000 Received: from post.thorcom.com (193.82.116.70) by marstons.services.quay.plus.net with SMTP; 21 Oct 2002 20:47:01 -0000 Received: from majordom by post.thorcom.com with local (Exim 4.10) id 183iRF-000519-00 for rsgb_lf_group-outgoing@blacksheep.org; Mon, 21 Oct 2002 20:42:09 +0100 Received: from [213.40.2.23] (helo=bodum.sout.netline.net.uk) by post.thorcom.com with esmtp (Exim 4.10) id 183iRE-000510-00 for rsgb_lf_group@blacksheep.org; Mon, 21 Oct 2002 20:42:08 +0100 Received: from [213.40.203.183] (helo=tcs1) by bodum.sout.netline.net.uk with smtp (Exim 4.04) id 183iQj-0001yc-00 for rsgb_lf_group@blacksheep.org; Mon, 21 Oct 2002 20:41:37 +0100 From: "G4WGT" To: "Rsgb_Lf_Group" Date: Mon, 21 Oct 2002 20:42:08 +0100 Message-ID: MIME-Version: 1.0 X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook IMO, Build 9.0.2416 (9.0.2910.0) X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Importance: Normal Subject: LF: LF Antenna.

I am receiving with a G3LNP balanced loop & pre-amp. My garden is quite small so the antenna will have to go upwards & give consideration to my neighbours. I have a 30 foot mast with a 4 Mtr beam, a VHF/UHF log periodic beam & VHF/UHF colinear vertical probably going up to 45 feet. I have thought of substituting these for a 6 foot x 2 inch fibreglass pole on top of my mast & using a similar arrangement to that described in the article by Alan Melia G3NYK & Finbar O'Conner EI0CF about spiral top loading. I can also wind inductance on the fibreglass pole to increase the top load inductance. What are your thoughts on this idea & if it sounds ok should I place the additional inductance above or below the spiral & if above what about an additional capacity hat on top of that. I will feed the device with a sloping vertical wire or on stand offs to keep the feed away from the mast & tuned at the bottom with a 12 inch diameter coil & variometer arrangement. Please give me your comments. Regards Gary (G4WGT) --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).

If anyone has a copy of 'VLF Engineering' handy you could check the actual figure in the chapter on transmitting antennas. The number of droopy radials may figure in this as well. 73 Dave ZL3FJ ----- Original Message ----- From: "Ashlock,William" To: Sent: Tuesday, October 22, 2002 3:21 AM Subject: LF: RE: Re: Re: Ant Questions > Hi Geri, > > >>Do not be tempted to droop the ends of any top wires. > > >...

Does the current really taper > away to zero at the open ends or is that effect swamped by ground capacitance > when it's only 0.5% of a wavelength above ground? The RF current at the open end of any wire is the vector sum of incident and reflected energy. Current "cancels" as that reflection co-efficient is nominally "-1", whereas voltage doubles, as that reflection co-efficient is nominally "+1". That is the basic mechanism for a "standing wave". Specific voltage and/or current distribution is influenced by the antenna specific environment, but it would generally not be "swamped" by the likes of ground capacitance, as wire segments "connecting to themselves" presents a much lower impedance. Mention of "displacement current" would probably be a red herring ..... 73, Bob ZL2CA From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 23285 invoked from network); 21 Oct 2002 18:55:03 -0000 Received: from marstons.services.quay.plus.net (212.159.14.223) by mailstore with SMTP; 21 Oct 2002 18:55:03 -0000 Content-Transfer-Encoding: 8bit Received: (qmail 8543 invoked by uid 10001); 21 Oct 2002 19:58:46 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from post.thorcom.com (193.82.116.70) by marstons.services.quay.plus.net with SMTP; 21 Oct 2002 19:58:46 -0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from majordom by post.thorcom.com with local (Exim 4.10) id 183hfu-0004nl-00 for rsgb_lf_group-outgoing@blacksheep.org; Mon, 21 Oct 2002 19:53:14 +0100 Received: from [147.197.200.9] (helo=hestia.herts.ac.uk) by post.thorcom.com with esmtp (Exim 4.10) id 183hfu-0004nc-00 for rsgb_lf_group@blacksheep.org; Mon, 21 Oct 2002 19:53:14 +0100 Received: from gemini ([147.197.200.44] helo=gemini.herts.ac.uk) by hestia.herts.ac.uk with esmtp (Exim 3.22 #1) id 183hYo-00074s-00 for rsgb_lf_group@blacksheep.org; Mon, 21 Oct 2002 19:45:54 +0100 Received: from [147.197.232.252] (helo=rsch-15.herts.ac.uk) by gemini.herts.ac.uk with esmtp (Exim 3.33 #1) id 183hYm-0006Ig-00 for rsgb_lf_group@blacksheep.org; Mon, 21 Oct 2002 19:45:52 +0100 Message-ID: <5.1.0.14.0.20021021194331.00a98c68@gemini.herts.ac.uk> X-Sender: mj9ar@gemini.herts.ac.uk X-Mailer: QUALCOMM Windows Eudora Version 5.1 Date: Mon, 21 Oct 2002 19:45:51 +0100 To: rsgb_lf_group@blacksheep.org From: "James Moritz" In-reply-to: <001101c2791c$905797e0$ea00a8c0@f3a3a2> MIME-Version: 1.0 X-MailScanner: No Virus detected Subject: Re: LF: 73kHz activity Content-Type: text/plain; charset=us-ascii; format=flowed X-Spam-Status: No, hits=0.1 required=5.0tests=DEAR_SOMEBODY,IN_REP_TO,SPAM_PHRASE_00_01version=2.42 Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Dear Laurie, LF Group, There's nothing really stopping me being QRV on 73k, except that I am rather tied up with work until the beginning of next month - hopefully see you then.

I see it like this..... If you put top load on a vertical you can increase its effective height and Rrad) from h/2 to close to h. If you have to droop them then you will loose some of this gain ....Laurie suggested to me it was of the order of 1/3rd of the overlap with the vertical. Yes the commercial boys use drooped loading wires on their Umbrella aerials..... see the pics of CFH on Dave's site, and DCF39, and the new Skelton 19kHz mast (cant remember the URL but it may be on Daves site as well) so it must be economic in their terms. BUT the thing is, Rrad is NOT everything that matters......increased capacity means a smaller loading coil, easier to make and less loss there, it also means a considerably reduced ground loss, particularly with amateur sized aerials. Since ground loss is our main "power thief" this part can well over-ride any small loss in Rrad because of the increase in aerial current from a given available PA power. You still need to keep it clear of the trees though. So by my reckoning, flat (level) is good..... but longer is better even drooped, and because the Rrad term is proportional to the square of the height ..even an extra 50% in vertical section height is well worth having, even if it then means drooping the top load a bit. An "ounce" of experimental measurement is worth several weeks playing with NEC !! Remote FS measurement as Bill says (and Jim has done extensively) is the only real test.

Thanks, that was the picture I'd arrived at. Does the current really taper away to zero at the open ends or is that effect swamped by ground capacitance when it's only 0.5% of a wavelength above ground?

Purely horizontal (or near horizontal) top hats. This test compared different droop angles of circular top hats, everything else kept constant.

That's in comparison with horizontal top loading. If a drooping top hat is all one can manage, it's generally better than none at all. However, consider that the far field radiation will be proportional to the sum of the vertical components of the current flow, and you can see that current in the downward segments will subtract somewhat from the end result. The trick is to make sure that the top loading is effective enough that the increased magnitude of overall current is enough greater to offset the partial cancellation.

My experience with many shapes of top hats is that it DOES reduce the radiation measured in the far field. The theoretical explanation I have seen is that the effective height is reduced due to the current foldback.

Several reports on the Reflector show that following my request there was quite a bit of activity over the weekend,  for which I am grateful.

I don't know whether there are any converts to LF as result of my talk but at least they had something to listen to.

In fact it comes out at 0.03 Hz at 136 kHz. Not the best but probably adequate for non-critical applications. Wolf DL4YHF suggests packing round the osc with styrofoam or similar to shield it from the fan airstream. Good idea. If anybody is interested in seeing my 706 osc stability graphs let me know.

I challenge that.

Firstly I have to admit that my comments are based more on 'thinking about it' than actually getting wires in the sky. I found time spent working through ON7YD's pages on aerials (takes a while to do it thoroughly) was well spent and I came away with a much better understanding of what matters. There's a section (or maybe a link to a piece) on top loading wires with some calculated examples of the benefit of top loading wires even if they hang downwards a bit.

On the Mk1, the fan is on permanently - perhaps this is the > fix! I can confirm this. I have seen the XDV signal on QRS and no wobble evident. I also have a 706 late MK1 and have worked various QRS speeds from 1WPM to 60 sec dots and see no wobble or instability. This system was used last year to work across to the USA and Canada on several occassions on 135.922 khz.. It is well within the tolerance required for the above QRS speeds, however if you need 0.00000000001 hz accuracy that might be a different story. A cold outside shed used as a shack during the winter might also blow you off course. Most modern rigs are suitable and stable enough for dividing down from HF freqs, you do not need any special ovens or 200 year old Chinese burnt in and aged xtals. > 73 de Mal/G3KEV > Mike, G3XDV > http://www.lf.thersgb.net > ==================== > > > From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 1299 invoked from network); 20 Oct 2002 13:52:59 -0000 Received: from marstons.services.quay.plus.net (212.159.14.223) by mailstore with SMTP; 20 Oct 2002 13:52:59 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: (qmail 4017 invoked by uid 10001); 20 Oct 2002 14:58:46 -0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from post.thorcom.com (193.82.116.70) by marstons.services.quay.plus.net with SMTP; 20 Oct 2002 14:58:46 -0000 Received: from majordom by post.thorcom.com with local (Exim 4.10) id 183GWu-0008Uz-00 for rsgb_lf_group-outgoing@blacksheep.org; Sun, 20 Oct 2002 14:54:08 +0100 Received: from [194.134.35.175] (helo=smtp4.wanadoo.nl) by post.thorcom.com with esmtp (Exim 4.10) id 183GWt-0008Uq-00 for rsgb_lf_group@blacksheep.org; Sun, 20 Oct 2002 14:54:07 +0100 Received: from nl9222@wanadoo (i2023.vwr.wanadoo.nl [194.134.215.239]) by smtp4.wanadoo.nl (Postfix) with SMTP id B0C163EB1E for ; Sun, 20 Oct 2002 15:54:05 +0200 (CEST) Date: Sun, 20 Oct 2002 15:54:2 +0100 From: "K.Versteeg" To: rsgb_lf_group@blacksheep.org X-Mailer: FoxMail 2.1 [en] MIME-Version: 1.0 Message-ID: <20021020135405.B0C163EB1E@smtp4.wanadoo.nl> Subject: LF: reports [was activity] Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Spam-Status: No, hits=4.8 required=5.0tests=DATE_IN_PAST_12_24,DEAR_SOMEBODY,FROM_ENDS_IN_NUMS, INVALID_DATE,SPAM_PHRASE_00_01,UPPERCASE_25_50version=2.42 X-Spam-Level: **** Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Dear Group Wednesday 16-10 F6BWO QRSS -44.7dB Friday 18-10 DL1EIE CW 559 PA0BWL QRSS -32.0dB Saturday 19-10 G3AQC CW 559 PA0BWL CW 599 PA3EGO CW 589 DF0WD CW 549 DL1EIE CW 549 G6RO CW 539 ON6ND CW 599 M0BMU CW 589 DK7SU CW 539 DJ5DI CW 559 DK1IS QRSS -40.6dB G3XDV QRSS -33.1dB F6BWO QRSS -36.8dB SM5EUF/5 QRSS -47.0dB DF8ZR QRSS -39.4dB DJ2LF QRSS -44.0dB Sunday 20-10 G3LDO CW 569 DK7SU CW 569 M0BMU CW 589 PA0BWL CW 599 OZ8NJ CW 549 DL1EIE CW 559 DF8ZR DFCW -34.7dB DF8ZR QRSS -34.0dB F6BWO QRSS -28.7dB G3XDV QRSS -27.1dB DN1VLF QRSS -31.3dB IK5ZPV QRSS -40.6dB Thanks for the signals, enough to be able to set up yet another receiver.

I had QSOs with DF8ZR and DF6NM. F6BWO was working several stations. At 1000 a very weak station replied to my CQ call. He was on about 137.725kHz. He called F6BWO first (who worked someone else instead), then he called me. Both times I missed the callsign and he did not reply to my QRZ. Does anyone recognise themselves from this? I have a screen shot if you want.

My problem is that the 706 will not >transmit below 13.9 MHz. Do you have a CB band over there that spans at least some frequencies in the 27.140 .. 27.560 MHz range ? You could then use an old CB transmitter and add a divide by two stage to your current divide by 100 divider chain. With 10 kHz channel spacing on the CB side, discrete frequencies at every 50 Hz could be generated on the 135 kHz band. While the spectral impurity of free running or PLL VCOs running in the upper HF or lower VHF range as used in many general coverage LF/MF/HF _receivers_ may make the reception of QRSS impossible, since the frequency deviation of the oscillator spurious signals are directly added to the received signal. However, if a transmitter signal is divided down by 200, the frequency deviation will also be divided by 200, so a 2 Hz spurious deviation at 27 MHz is 0.01 Hz at 135 kHz.

If you go to QRZ.COM web site you will find the info to mod your 706 for general coverage. Dividing down from 13.6/13.7 mhz by 100 works well and is stable enough for most applications like QRS. Stability depends on temperature environment. For QRS leave the rig switched on some hours before use and in a warm room NOT in an outside garden shed !! 73 and GL de Mal/G3KEV > > Kevin > ZL4MD > > From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 26117 invoked from network); 20 Oct 2002 08:47:50 -0000 Received: from warrior.services.quay.plus.net (212.159.14.227) by mailstore with SMTP; 20 Oct 2002 08:47:50 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: (qmail 14166 invoked from network); 20 Oct 2002 08:49:14 -0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from post.thorcom.com (193.82.116.70) by warrior.services.quay.plus.net with SMTP; 20 Oct 2002 08:49:14 -0000 Received: from majordom by post.thorcom.com with local (Exim 4.10) id 183BlG-00076W-00 for rsgb_lf_group-outgoing@blacksheep.org; Sun, 20 Oct 2002 09:48:38 +0100 Received: from [152.163.225.105] (helo=imo-r09.mx.aol.com) by post.thorcom.com with esmtp (Exim 4.10) id 183BlF-00076N-00 for rsgb_lf_group@blacksheep.org; Sun, 20 Oct 2002 09:48:37 +0100 Received: from DL4YHF@aol.com by imo-r09.mx.aol.com (mail_out_v34.13.) id l.12d.19242060 (3874) for ; Sun, 20 Oct 2002 04:48:00 -0400 (EDT) From: DL4YHF@aol.com Message-ID: <12d.19242060.2ae3c7bf@aol.com> Date: Sun, 20 Oct 2002 04:47:59 EDT To: rsgb_lf_group@blacksheep.org MIME-Version: 1.0 X-Mailer: AOL 6.0 for Windows XP DE sub 50 Subject: Re: LF: ICOM 706 Mk2 Content-Type: text/html; charset=windows-1252 X-Spam-Status: No, hits=1.9 required=5.0tests=NO_REAL_NAME,SPAM_PHRASE_02_03,USER_AGENT_AOLversion=2.42 X-Spam-Level: * Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Content-transfer-encoding: 8bit Hi Walter, Kevin and group;

I use an (old) IC706 for longwave and am quite happy with it.

>> Total wobble is only at 136 is only a few Hz and doesn't normally matter but it does when you're looking for 0.01 Hz!<<
There must be something wrong, if the wobble is in the HERTZ region on 136kHz... imagine what would happen if the same "relative" wobble happened on 144MHz with a narrow CW filter !
I can not confirm that the oscillator is wobbly at all (at least not in the 10-milliHerz-region). I don't know what the oscillator in the MK2 looks like, but in the old 706 it has an extra metal shield, and sits between other solid "metal cubes" on the lower side of the PCB (far away from the PA).

For very high accuracy, the oscillator can even be tied to an external reference (like OCXO), because the master osc frequency is 30MHz, which can easily be "PLL'ed" to a 5- or 10-MHz clock.


About the "yellow wire" mod: DONT do it, it was only used to increase the RX sensitivity outside the 144 MHz band of the old IC706.
There is a web site which has all kind useful and unuseful mods for most transceivers; just googling for it (I don't have it at hand).

My ancient IC-706 Mk1 works absolutely fine receiving 120s QRSS after a few minutes warm up. On the Mk1, the fan is on permanently - perhaps this is the fix!

Saturday I worked SM1LCA in CW on 136kHz. Operator's name Kjell, Loc. JO97, must be Gotland Isld. He had some QRM but was 549 here (at DF0WD, JO42).

Dear OM Kjell, if you are on this reflector, are you the same Kjell frequently operating in CW contacts on 144 MHz, callsign SK6DK ? The "VHF-Kjell" often mentioned getting QRV on 136kHz station.

Besides this: Good activity on 136kHz as already mentioned by Alan.

Its local oscillator is rather "wobbly" due to the action of its internal fan and you won't find it stable enough for narrow-band QRSS etc. I have one and I installed the "hi-stab" option which made it even worse by introducing a second TCXO-induced wobble. Total wobble is only at 136 is only a few Hz and doesn't normally matter but it does when you're looking for 0.01 Hz! ICOM told me the 706 was never designed for ultra-stable narrow-band work, only for HF mobile. I use an old ICOM 720 with purple diode wire cut which enables Tx on all frequencies and divide down from 13.6 MHz. After an hour or so for warm-up it's perfectly acceptable.

I challenge that. My umbrella antenna 18m high with 5 pieces of top-load radials sloping downwards (each about 7 m long) works fine (see sketch at http://www.qru.de/station.htm), with an antenna "gain" of roughly - 30 dB. One of the key factors that had increased my ERP was to put up my loading coil 1/3 way up the fiberglas mast so that any losses occuring due to high voltages due to surrounding trees and walls are reduced.

Expanding on one point: > >I am assuming (within practical limits) that as much capacitance as > possible in the antenna is beneficial. It will resonate with lower > inductance and therefore lower resistive losses. > > Yes, that is correct. Correct in respect of an ohm or two in coil loss (equivalent series R), but more complex in terms of net ground loss which is likely in the range of tens of ohms to a hundred ohms, and is unlikely to change much with variation in spacing of parallel wire top loading. The capacitance should be maximised in the top loading, but not in the "up-wire" (multiple up-wires, if needed, should taper to a single connection point at the lower end). Within reasonable limits, the up-wire should be clear of the house and tree, and rise vertically from the top of a ground mounted loading coil. The "environmental soakage" from the lower part of the up-wire (which is all at high voltage) is another insideous factor that increases equivalent series resistance. 73, Bob ZL2CA From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 18791 invoked from network); 19 Oct 2002 15:51:18 -0000 Received: from warrior.services.quay.plus.net (212.159.14.227) by mailstore with SMTP; 19 Oct 2002 15:51:18 -0000 Received: (qmail 22482 invoked from network); 19 Oct 2002 15:50:53 -0000 Received: from post.thorcom.com (193.82.116.70) by warrior.services.quay.plus.net with SMTP; 19 Oct 2002 15:50:53 -0000 Received: from majordom by post.thorcom.com with local (Exim 4.10) id 182vrv-0002mU-00 for rsgb_lf_group-outgoing@blacksheep.org; Sat, 19 Oct 2002 16:50:27 +0100 Received: from [62.253.162.43] (helo=mta03-svc.ntlworld.com) by post.thorcom.com with esmtp (Exim 4.10) id 182vrv-0002mL-00 for rsgb_lf_group@blacksheep.org; Sat, 19 Oct 2002 16:50:27 +0100 Received: from oemcomputer ([213.104.104.27]) by mta03-svc.ntlworld.com (InterMail vM.4.01.03.27 201-229-121-127-20010626) with SMTP id <20021019155025.IAFA292.mta03-svc.ntlworld.com@oemcomputer> for ; Sat, 19 Oct 2002 16:50:25 +0100 Message-ID: <000c01c27787$566bf080$1b6868d5@oemcomputer> From: "mike.dennison" To: rsgb_lf_group@blacksheep.org References: Date: Sat, 19 Oct 2002 16:50:58 +0100 MIME-Version: 1.0 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 Subject: LF: Re: Ant Questions Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Spam-Status: No, hits=-1.1 required=5.0tests=EMAIL_ATTRIBUTION,REFERENCES,SPAM_PHRASE_02_03, USER_AGENT_OEversion=2.42 Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group G0CZD wrote: >I'm about to put up a 136kHz Antenna and have a couple of questions. >I don't have much space in the garden, approx 20m from the apex of the roof to a 20m high poplar tree in the opposite corner.

I don't have much space in the garden, approx 20m from the apex of the roof to a 20m high poplar tree in the opposite corner. I am considering an offset 'T' with a multi-wire top. I am assuming (within practical limits) that as much capacitance as possible in the antenna is beneficial. It will resonate with lower inductance and therefore lower resistive losses. The RSGB LF experimenters h/b (p52) suggests that 2 wires separated by 100mm will provide 39% increase in capacitance. Is it safe to assume that putting multiple wires up at 100mm will provide a compound percentage increase? I am considering 6 wires at 100mm separation. Are there any better solutions - I have neighbours I wish to remain on speaking terms with... What effect does height have on the antenna? I can fairly safely get the antenna up to 10m above ground level without too much difficulty. Will there be any significant benefit to raising the tree end of the antenna to say 15m. I will probably feed the aerial at about 5m from the house with two coils, one at ground level and a second 2 litre coke bottle sized coil at the junction between the vertical and the capacitive top. Sorry for the newbie type questions. Getting this right first time is important, neither the tree nor the apex of the house are particularly easy to get at and I don't want to do it too many times... 73, Martyn G0CZD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 19010 invoked from network); 19 Oct 2002 12:24:38 -0000 Received: from murphys.services.quay.plus.net (212.159.14.225) by mailstore with SMTP; 19 Oct 2002 12:24:38 -0000 Received: (qmail 21828 invoked from network); 19 Oct 2002 12:24:08 -0000 Received: from post.thorcom.com (193.82.116.70) by murphys.services.quay.plus.net with SMTP; 19 Oct 2002 12:24:08 -0000 X-SQ: A Received: from majordom by post.thorcom.com with local (Exim 4.10) id 182sd3-00027T-00 for rsgb_lf_group-outgoing@blacksheep.org; Sat, 19 Oct 2002 13:22:53 +0100 Received: from [194.73.73.93] (helo=rhenium.btinternet.com) by post.thorcom.com with esmtp (Exim 4.10) id 182sd3-00027K-00 for rsgb_lf_group@blacksheep.org; Sat, 19 Oct 2002 13:22:53 +0100 Received: from [213.122.62.213] (helo=main) by rhenium.btinternet.com with smtp (Exim 3.22 #8) id 182sd2-0006lk-00 for rsgb_lf_group@blacksheep.org; Sat, 19 Oct 2002 13:22:53 +0100 Message-ID: <000601c2776a$3f9ba980$d53e7ad5@main> From: "Alan Melia" To: "LF-Group" Date: Sat, 19 Oct 2002 13:22:48 +0100 MIME-Version: 1.0 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 Subject: LF: Sat morning activity Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Spam-Status: No, hits=1.0 required=5.0tests=SPAM_PHRASE_00_01,USER_AGENT_OEversion=2.42 X-Spam-Level: * Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Hi all, I hope this mornings activity helped provide to listening for Dick's new converts.

Has about 12ft of coax and BNC which I extended by another 12ft with RG58. Works fine with the HP Z3801a. This only tracks six satallites but "what a machine" for those who do not want to built or prefer to "swing the bucks" in the words of Jay, W1VD. The Z3816a I think is the 8 satellite version but I have only seen three of those so far and they were expensive. Extensive information on www.realhamradio.com I have built a frequency reference using a Racal Dana 5MHz ovened oscillator and now watch this and the 10MHz output from the HP on 0.1uS/cm on the scope. The HP has been running two weeks and now predicts remaining within 2.4uS during the initial 24 hours of losing GPS lock. 73, Brian At 08:23 19/10/2002 +0100, you wrote: >Further to Andy, G4JNT's talk at the LF Forum (RSGB HF COnvention) last >weekend, and his article in RadCom, Frank, K0BRA, mentioned a cheap source >of surplus Motorola ACS1397 8 Channel GPS modules from BG Micros >(http://www.bgmicro.com). > >Anyone wanting to build a GPS locked frequency source may be interested to >know that the modules are advertised at $US14.95 and arrived here in the UK >three days after ordering over the Internet.

You might find those Motorola chips already put 5v on the antenna line. There are also surplus Garmin all-in-one antenna units around - 12v in, data out. Some were on sale at the Telford rally for Ł5, I'm told.

Tonight I'm going to deliver my talk on LF for the 10th time. It will be at a VERON radio club at a town called Schagen (NE of Amsterdam).

I always tell my audience that the best chance to hear normal morse code traffic on the LF band is on Saturday and Sunday morning.

Unfortunately I will be away from home on Saturday and possibly Sunday as well.

So I would be grateful if other stations decide to be on the air this weekend so  possible newcomers to the band will have something to listen to.

Reading Dave's recent message it looks like 136 khz is not yet available in the USA.
I was hoping for some 136 qso's this winter across the deep blue. In the meantime I will work xband like last year all being well. I will tx on 135.922 Khz plus/minus in a vacant slot around this freq and listen on 7025 khz again plus/minus qrm or any freq mutually agreed.

Mal, when I first started trying all these programs like ARGO, Spectran etc I had an ole 486 machine with a basic Creative sound card and 64M of RAM and always seemed to be a bit on edge with them working...I finally just said the heck with it and went with a nice Dell(used) 800mhz and 256M of RAM and a Creative128 sound card and magically these programs cruise along with no sign of hic-up.Sure is nice .That may not be an option but the point is they do require some help HI!!!

Good luck to all in the USA in their attempts to get the band.

The FFT routine has now a selectable non-linear processing option, according to the formula given by Alex and also a selectable "Hendrixizer", which uses the 10th radix of the normalized input signal as a limiting function. I did some quick test yesterday evening, but there were no QRSS signals (hi) so I used some weak CW signals on the 20 m band; as noted by Jim, the two non-linear processing options are in some way related, since the spectra they produce are somewhat similar, but certainly more testing with real LF signals is needed... As a last note, this release should correct also the dependencies on the fftw library, a bug which prevented compilation on systems without this library installed... Happy experimenting with non-linear processing! 73 de Claudio, IN3OTD -- Home Page: http://www.qsl.net/in3otd/ Alex wrote: [snip] > So it is very simple to realize!

Hello All
The argo crash info on my screen says:
Fatal error 0E at 0028 : C02987A8 in VXD VWIN32(05) + 000012D0
The screen goes blue with the above info.
The crashes are irregular maybe after anything from 20 mins to a few hours.
Only argo running when this happens, no other applications running, so its not a multi tasking problem.
So far no crashes with Speclab or other qrs progs etc
I gather some others get the same problems at times, on various PC's. I am sure Alberto will put it right when he gets time.

I will play with the mentioned function in the time domain soon. Will let you know when more can be said about it.

BTW Alex -  I still have the complete "C" sources of my ancient DOS waterfall program, would you like to have it ? (on the PC I use at the present time, its useless because of incompatible VGA- and audio card)

Certenly if sinusoidal QRM is present nonlinear processing should give bad resiption due to blocking and intermodulation. Prefiltering passband should be as wide as posible but all sinusoidal QRM should be rejected. So some art is needed to tune RX passband and A parameter to get best reciption. May be it is bad for professional porpose but it is wonderfull for HAMing...

Hello All
The argo crash info on my screen says:
Fatal error 0E at 0028 : C02987A8 in VXD VWIN32(05) + 000012D0
The screen goes blue with the above info.
The crashes are irregular maybe after anything from 20 mins to a few hours.
Only argo running when this happens, no other applications running, so its not a multi tasking problem.
So far no crashes with Speclab or other qrs progs etc
I gather some others get the same problems at times, on various PC's. I am sure Alberto will put it right when he gets time.

The conditions seem to be that the noise within the receiver passband is wide band in nature; if strong narrow-band signals are also present, intermodulation and/or blocking effects occur. Due to the non-linear term in Alex's function above, I expect the same would apply. But if there is nothing but weak signals and noise within the RX passband, simply clipping the signal gives a significant improvement. The effects of clipping were found by accident, so I would not be surprised if Alex's more scientific approach also gave benefits - it is certainly true that most of the noise on LF is nothing like white noise. Looking at the function Alex suggests, and assuming S(t)*S(t)] means S(t)^2, when S(t) is small, S1(t) is approximately S(t)/A, ie. linearly proportional. When S(t) is very large, S1(t) is approximately 1/S(t), ie. ~=0. The gradient "turns over" when S(t)^2 = A. So the function is like a software noise blanker, removing the high amplitude parts of the input signal, with the value of A setting the threshold. One can intuitively see how this could work with LF noise consisting mainly of spikes of QRN Well, now all I have to do is sit back and relax while the spectrogram software guys get it working... :-) Cheers, Jim Moritz 73 de M0BMU From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 14019 invoked from network); 15 Oct 2002 12:32:33 -0000 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit Received: from warrior.services.quay.plus.net (212.159.14.227) by mailstore with SMTP; 15 Oct 2002 12:32:33 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: (qmail 25874 invoked from network); 15 Oct 2002 12:31:50 -0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from post.thorcom.com (193.82.116.70) by warrior.services.quay.plus.net with SMTP; 15 Oct 2002 12:31:50 -0000 Received: from majordom by post.thorcom.com with local (Exim 4.10) id 181Qpz-000625-00 for rsgb_lf_group-outgoing@blacksheep.org; Tue, 15 Oct 2002 13:30:15 +0100 Received: from [194.217.242.85] (helo=anchor-post-35.mail.demon.net) by post.thorcom.com with esmtp (Exim 4.10) id 181Qpz-00061w-00 for rsgb_lf_group@blacksheep.org; Tue, 15 Oct 2002 13:30:15 +0100 Received: from telemetry.demon.co.uk ([194.222.19.114]) by anchor-post-35.mail.demon.net with esmtp (Exim 3.36 #2) id 181Qpy-0005Oz-0U for rsgb_lf_group@blacksheep.org; Tue, 15 Oct 2002 13:30:15 +0100 Message-ID: Date: Tue, 15 Oct 2002 07:47:13 +0100 To: rsgb_lf_group@blacksheep.org From: "Tom Boucher" In-reply-to: <000501c27216$d7b05620$35ccfc3e@ian> MIME-Version: 1.0 X-Mailer: Turnpike Version 3.03a Subject: Re: LF: Activity X-Spam-Status: No, hits=0.3 required=5.0tests=DATE_IN_PAST_03_06,IN_REP_TO,SPAM_PHRASE_00_01version=2.42 Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Ian Thanks for the nice report.

As You are working in computer signal processing it seems result of some my reseach (not published) should be interesting for You. Main idea is as folow. Conventional algorithms of signal processing (say FFT) are optimal if noise is Gauss distributed. But is spheric noise Gauss distributed realy? My investigation show that this is wrong. Really spheric noise (QRN) is distributed not by Gauss function exp(-x*x). Much better aproximation is Lorentz function 1/( 1 + x*x). But conventional signal processing is not optimal in such a noise! As it was shown by me optimal signal processing in Lorenz noise require to solve very complex nonlinear integral equation. But if one solve the equation by iteration procedure he get as folows. First iteration yeld conventional linear processing. But next iteration yelds that optimal is not linear filtration of signal but nonlinear instant conversion by a function x/(1 + x*x) and THAN conventional linear processing. Incoming signal level should be controled to give mean noise level equal to 1. So it is very simple to realize! The only addition is input convertion of the incoming signal S1(t) = S(t)/[A + S(t)*S(t)] where S(t) if signal from RX. Parameter A shold be controlled to get best reciption. Than signal S1(t) is processed by conventional procedure (say FFT). It is very interesting to try such an algorithm. 73 de RA9MB/Alex http://www.qsl.net/ra9mb From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 14305 invoked from network); 15 Oct 2002 00:03:13 -0000 Received: from marstons.services.quay.plus.net (212.159.14.223) by mailstore with SMTP; 15 Oct 2002 00:03:13 -0000 X-Priority: 3 Received: (qmail 19380 invoked by uid 10001); 15 Oct 2002 01:06:51 -0000 X-MSMail-Priority: Normal Received: from post.thorcom.com (193.82.116.70) by marstons.services.quay.plus.net with SMTP; 15 Oct 2002 01:06:51 -0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from majordom by post.thorcom.com with local (Exim 4.10) id 181F9c-0004e7-00 for rsgb_lf_group-outgoing@blacksheep.org; Tue, 15 Oct 2002 01:01:44 +0100 Received: from [193.82.59.20] (helo=post.omnieng.co.uk) by post.thorcom.com with esmtp (Exim 4.10) id 181F9c-0004dy-00 for rsgb_lf_group@blacksheep.org; Tue, 15 Oct 2002 01:01:44 +0100 Received: from [202.99.254.3] (helo=202.99.254.17) by post.omnieng.co.uk with smtp (Exim 3.36 #1) id 181F9a-0006zl-00 for rsgb_lf_group@blacksheep.org; Tue, 15 Oct 2002 01:01:43 +0100 MIME-Version: 1.0 Date: Tue, 15 Oct 2002 00:04:02 UT From: "Rick Ruben" To: rsgb_lf_group@blacksheep.org Return-Errors-To: X-Sender: "Rick Ruben" X-Mime-Flavour: eJxjYmFi4OF3cYmPltNTlVYyiXdxKg6LDA8J9tJUVzPJ1nQKAwBsVwdt Message-ID: Content-Transfer-Encoding: 8bit Content-Type: text/html; charset=windows-1252 Subject: LF: hi X-Spam-Status: No, hits=2.6 required=5.0tests=FROM_HAS_MIXED_NUMS,NORMAL_HTTP_TO_IP,SPAM_PHRASE_00_01, WEB_BUGSversion=2.42 X-Spam-Level: ** Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group I remembered this time friend!

Today Argo has been running for about 4 hours and no crashes but there has been no audio input, so maybe as someone has suggested input signal has something to do with it.
It has been running on both the main and portable PC.
Win 98 v 2 on main and Win 95 on portable, 166 mhz machines.
There is some conflict somewhere in the Argo S/ware because the machines do not crash with SPECLAB and any other prog.
Tnx to all for their observations. I am sure it will be sorted out.

Hi Alberto and all,

on two computers, I did experience Argo (build 128) crashing Windows 98 occasionally but not often, and I couldn't make out a connection to any specific activity. However there is a strange effect about the peak readout, once in a while it overwrites the top left corner of the screen instead of staying in its place in Argo's window. - On a 233 MHz PII, all modes down to 90s dots (10mHz) produce nice lines, whereas 120s dots tends to be blurred by glitches, presumably caused by lost audio data.


Hi Markus and the group,

   yes, I am aware of a couple of bugs present in the distributed version of Argo.
One is an infrequent hang caused by a memory leak, the second is  what you describe,
i.e.  an erroneous writing of the peak value in the upper left corner of the desktop,
caused by a timing glitch between different threads.

Both have been corrected, but I haven't distributed the updated version yet, as I
was intending to do some other modifications as well, but then it was all left in
a suspended-animation status, due to a variety of reasons, whose list is of
no relevance here.

I am intending to resurrect that project, at least up to the point of releasing
a version with those errors corrected. Just give me a couple of weeks.

There is a version of this library that does not need X-Windows but uses directly the VGA modes of the video card, only for PC-like systems, while the X-Windows version works also on workstations (anyone using a Sun or HP workstation for doing LF work? (hi) ) I'll take a look at the possibility of having a non X-Windows version, but it will probably take some time before adapting glfer to this library. Regarding the hardware requirements, for the basic spectrogram and TX keying functions I have used a Pentium 133 and it worked fine; the other spectral estimators could need more CPU power (especially the ARMA), depending on the settings of the various parameters. On which system are you planning to use glfer? 73 de Claudio, IN3OTD -- Home Page: http://www.qsl.net/in3otd/ > Hi, Claudio and Group. > > On Fri, 11 Oct 2002, Claudio Girardi wrote: > > > Dear LF Group, > > I have just finished a new release of glfer, a Linux application combining a > > spectrogram viewer and a QRSS/DFCW keyer.

on two computers, I did experience Argo (build 128) crashing Windows 98 occasionally but not often, and I couldn't make out a connection to any specific activity. However there is a strange effect about the peak readout, once in a while it overwrites the top left corner of the screen instead of staying in its place in Argo's window. - On a 233 MHz PII, all modes down to 90s dots (10mHz) produce nice lines, whereas 120s dots tends to be blurred by glitches, presumably caused by lost audio data.

Anyhow, even if there was a bug somewhere in there, it doesn't seem to cause big trouble here, and certainly does not compromize Argo's value as an extremely useful tool and a great piece of work.

Regards
Markus, DF6NM

One other thing that crashed early Spectran was if I ran the audio input a little too high...hanging into the red region too much. It would first cause the fan in the laptop to kick in, indicating I suppose, that the processor was being stressed and having trouble keeping up with the program...and then it would crash.
Does it crash only when you are running in screen capture 'activated' mode? There might be a clue there if so.

I get a blue-screen crash every so often with Argo 128, it happened at Windsor last night. I went back to an old build, 117, and it ran OK but I'm not sure if it is 100% reliable. That is on Win95 on a very slow P100. I have also had crashes, but less common, on a 266MHz machine running 98.
 
Cheers.
Dave G3YXM.
 
Hello Dave and I hope you enjoyed Windsor and the meeting. You were putting out a good signal any time that I heard HFC active..
Yes that is exactly what I am getting. A crash on a blue screen, with a VXD error.
Here using win 98 v 2 so not sure what the problem might be, it might run half an hour or more then the dreaded blue appears !!
Tnx the info and hpe cul de Mal/G3KEV

Hello All
I am getting Fatal Error VXD messages and crashes with ARGO on my main PC/Windows.
The same thing is happening on my Portable PC so it looks like a bug in ARGO. Does anyone else have this problem.
All other s/ware runs ok and no crashes. Is there a cure for an otherwise excellent prog.
Re starting the prog only lasts a short time before another crash but if the computer is closed down completely ie restarted then it runs longer before a crash.

Just a thought, but when I first started using Spectran a similar problem arose with my laptop. There was a conflict with the laptop being in the 'go-to-less power consumption' mode after so many minutes of no keyboard/mouse activity; perhaps there is something similar happening there...or maybe a 'screen-saver' conflict, especially if it is crashing after 10 minutes of no apparent activity from the keyboard?

The LF demonstration station  benefited from some heavy overnight rain and with the addition of another 80 feet to the top loading managed an improved 2.4 amps of antenna current.
Early this morning M0BMU, G3YXM G3XTZ and I, tried adding an inductor in series to one of the earth radials. We hoped that resonating the radial would more accurately simulate a quarter wave counterpoise. We measured the earth current in the radial and resonating increased the figure by 300%.  Sadly, the antenna current remained the same.......Oh well, more work required.

I get a blue-screen crash every so often with Argo 128, it happened at Windsor last night. I went back to an old build, 117, and it ran OK but I'm not sure if it is 100% reliable. That is on Win95 on a very slow P100. I have also had crashes, but less common, on a 266MHz machine running 98.
 
Cheers.
Dave G3YXM.

Hello All
I am getting Fatal Error VXD messages and crashes with ARGO on my main PC/Windows.
The same thing is happening on my Portable PC so it looks like a bug in ARGO. Does anyone else have this problem.
All other s/ware runs ok and no crashes. Is there a cure for an otherwise excellent prog.
Re starting the prog only lasts a short time before another crash but if the computer is closed down completely ie restarted then it runs longer before a crash.

Hello All

I am getting Fatal Error VXD messages and crashes with ARGO on my main PC/Windows.

The same thing is happening on my Portable PC so it looks like a bug in ARGO. Does anyone else have this problem.

All other s/ware runs ok and no crashes. Is there a cure for an otherwise excellent prog.

Re starting the prog only lasts a short time before another crash but if the computer is closed down completely ie restarted then it runs longer before a crash.

Hi Dave, David and the Group:
 
I saw the signals from MB2HFC last night, "O" report. I answered the CQ´s but the radiated power difference is too high and my signals couldn´t arrive there.

MB2HFC will be be on the air again from the HF convention on Sunday morning from about 0900 to 1200 utc. Normal working frequency is 136.8.
Thanks to Ian and Mal for the reports.
We have had reasonable results so far with a good antenna against a very poor earth!
So far we have worked 5 Gs, 3 DLs, 1 F and 1 ON station. A few more QSOs would be very welcome..
CU on 136.

Thanks for the QSO with DF0WD on saturday. Your signal was 559, perfectly readable here in JO42 square (you got everything ok David).
Compared to your 600W, 20m V + 23m topload (even with a poor earth) my signal must have been many many dB's weaker, so the RX conditions at Windsor cannot be that bad.

Also solid copy on late saturday evening when MB2HFC turned to QRSS/DFCW. I had no PC / Waterfall at DF0WD, but the dots and dashes could easily be written on paper for decoding !

Wkd SM6BHZ (Gus) in moderate speed CW a bit earlier on saturday, guess he is in your log by the time you receive this.

Have a good time at Windsor,  CUL

So the faked address, in general, does not exist at all! Bugbear sends itself out to addresses harvested from saved messages (not just the inbox) and cached web pages on the victim's machine. There is, however, some info in the headers of a bugbear message which may help you find and warn the victim. I did not receive "Mike's" message myself, but if you still have the message on your system, with all headers, here's what to look for: Below are headers from a bugbear message I got "from" another mailing list.

The 'Received:' headers are all real. Bugbear uses the victim's normal outgoing SMTP server to send mail, so the top header (typically generated by your ISP) indicates that he probably has a btinternet.com address. The second header (typically generated by his ISP) will usually give the real computer name (in this case 'msalt2') his IP address at the time (in this case 213.122.88.90), and the sender's time zone (+0100). People often choose a computer name which matches their first or last name. Or, if you can search an archive including full headers, you may find a post with the same host name. You can try a tracert command to the IP involved; the names of the routers in the path may give a clue to the victim's city. If the victim has a broadband connection with a static or rarely changing IP, you might find the address in a prior post. If you can't easily identify the victim, send me a copy of the headers and I'll try to puzzle it out. 73, Stewart From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 19105 invoked from network); 12 Oct 2002 23:36:30 -0000 Received: from murphys.services.quay.plus.net (212.159.14.225) by mailstore with SMTP; 12 Oct 2002 23:36:30 -0000 Received: (qmail 756 invoked from network); 12 Oct 2002 23:35:45 -0000 Received: from post.thorcom.com (193.82.116.70) by murphys.services.quay.plus.net with SMTP; 12 Oct 2002 23:35:45 -0000 X-SQ: A Received: from majordom by post.thorcom.com with local (Exim 4.10) id 180Vmw-0000uT-00 for rsgb_lf_group-outgoing@blacksheep.org; Sun, 13 Oct 2002 00:35:18 +0100 Received: from [194.73.73.92] (helo=carbon.btinternet.com) by post.thorcom.com with esmtp (Exim 4.10) id 180Vmw-0000uK-00 for rsgb_lf_group@blacksheep.org; Sun, 13 Oct 2002 00:35:18 +0100 Received: from host213-123-44-236.in-addr.btopenworld.com ([213.123.44.236] helo=main) by carbon.btinternet.com with smtp (Exim 3.22 #8) id 180Vmv-00026G-00 for rsgb_lf_group@blacksheep.org; Sun, 13 Oct 2002 00:35:17 +0100 Message-ID: <000501c27247$f7d26340$a34f7ad5@main> From: "Alan Melia" To: "LF-Group" Date: Sun, 13 Oct 2002 00:31:47 +0100 MIME-Version: 1.0 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 Subject: LF: Please check ....

The message mentioned by Andre is not from Mike, I believe, (someone else received a spoofed message with his name about 10 days ago.) but as Andre, Brian, and myself have received the same message today it would seem that someone's machine still has an undectected virus which is using his address list of Reflector members and / or message Inbox (which must be quite big for Mike changed his address some time ago, I only have an archive folder back to April 2002 ...not in the Inbox...and it is not in there.....I believe that Mike announced the change last year.....so whoever is infected has an enormous INbox folder ) to forge the instantly recognisable message with a 69kB attachment (a size that would not pass through the reflector) If you have not already checked your machine with a data update at about 30th Sept 2002 or later please run a system scan. I am led to believe that NortonAV will not run properly when the PC is infected,but this is only anecdotal evidence. If you are in doubt please read back reflector mail from Dave G3YMC, which contains URLs with information. Sorry to be a harbinger of bad news to someone.

We have had reasonable results so far with a good antenna against a very poor earth!
So far we have worked 5 Gs, 3 DLs, 1 F and 1 ON station. A few more QSOs would be very welcome..

Hi All
Does anyone have an old 4 metre transverter, valve or transistor etc that is surplus to requirement that I could buy. Sorry the topic is not LF related but maybe someone has deserted VHF for LF and no longer needs the equipment.
Tnx de Mal.G3KEV

G3OLB 589; MB2HFC569. This was using the old loading coil and vacuum C, but since the tx is still languishing under the bench waiting completion it was not possible to join in. The new coil with vario is far too big for 136 but seems to resonate pretty well on 73 (which is the real interest) so it should not be too long now before there is resident activity from GI. Had to cry off the convention, unfortunately, but that's life. Will post again as things progress. Ian.

Just a brief Saturday morning update:

The LF demonstration station made it onto the band at 18.00UTC last night.

The antenna installed at Savill Court finally turned out to be an inverted L with the vertical section at 70 feet with a 150 foot topload at the same height.
Many thanks to everyone who assisted, including 'LF' conference DX visitors
Wil  PA0BWL , Frank Gentges K0BRA and also Phil visiting from VK6 land.

Reception conditions at the site are very good with a minimum of local noise although finding a good earth on the chalky hilltop is challenging.
Thanks to  G3HEJ  M0BMU G3XIZ and ON6ND for QSOs through the static crashes last night on 136.80k

MB2HFC  (not GB4RS as anticipated) will be intermittent today as Saturday has several presentation on LF topics. However, tonight's 18.00 - 24.00 operation will go ahead as planned with the latter 4 hours on 137.710 QRSS

Unfortunately Brian has suffered a computer failure ( well, it has been working awfully hard this last 12 months !) He was intending to do an update to his system anyway around about now, so this has brought the process forward a bit. I will post some "wild guesses" occasionally, particularly if any Trans-atlantic activity starts up, but it is difficult to understand what might be happening without live data. Also I do not have anything from CFH or SXV these days (though I am sure Greek and southern European stations and East Coast stations are quite pleased about that !!) I suggest anyone wanting a detailed report about conditions tries the KN4LF site (linked from my page). Although Tom is biassed towards BC and MF, his weekly reports are extremely good. With the arrival of LF allocations in the US I am sure Tom will shift some emphasis to 136kHz as well.

As usual, the code is released as open source and can be downloaded from http://www.qsl.net/in3otd/glfer.html . Main news are the possibility of reading the audio data not only from the soundcard but also from a WAV file and the possibility to select a spectral estimator among several different types. This is a brief description from the README file included in the package: The available spectral estimators are: - the "classical" periodogram, which is obtained as the square of the absolute value of the discrete Fourier transform, after tapering the data with a "window function", selectable among the Hanning, Blackman, Gaussian, Welch, Bartlett, Rectangular, Hamming and Kaiser types. As usual, the FFT number of points and the overlap between data blocks can be freely changed. - the multitaper method, which is a weighted combination of periodograms computed with different windows, all belonging to the same family and having certain peculiar properties. This method was described by David J. Thomson in "Spectrum Estimation and Harmonic Analysis", Proc. IEEE, vol.70, Sep. 1982. Besides the FFT size and overlap, it is possible to change also a relative bandwidth parameter and the number of windows to use for the analysis. This method requires more CPU power than the first one, due to the fact that several FFTs are performed on the same block of data, using different windows. The resulting spectrum is similar to a classical periodogram, but with much less variance (i.e. less variation in the background noise [speckle]). Performances are also similar to the periodogram, maybe it makes detection of QRSS signals a little easier, but this doesn't means they are always more readable. Please try it and let me know how it works. - a (so called) "high performance" ARMA model, which assumes a certain model for the input data (in this case it assumes white noise plus sinusoids, rather strange eh? 8-)) and tries to extract the parameters of this model (sinusoids frequency and strenght) from the data. Reference article for this implementation is "Spectral Estimation: An Overdetermined Rational Model Equation Approach", by James A. Cadzow, Proc. IEEE, vol.70, Sep. 1982. At present this method is still experimental. There are two parameters that can be varied: t is the number of samples used for computing the samples autocorrelation and p_e is the order of the AR model. This latter must be less than t, and both number should be fairly small in order not to overload the CPU. The number of sinusoids is estimated autimatically from the samples autocorrelation. Use the default numbers as a starting point and experiment! Unfortunately this spectral estimator performs poorly with a non-flatt noise spectrum (as we have usually in the RX audio, due to the IF filters) and high noise levels. On the other hand it provides a very good visual SNR with signals not buried in the noise... I will try different related methods in the future, in the hope of finding one really useful for sigging weak signals out of noise. The transmitter control part of the program is capable of keying the PA according to the QRSS (slow CW) or DFCW modes. The transmission timing, as dot length and PTT delay, can be freely varied. A sidetone function can be used as a monitor for the transmission and gives also the two (freely selectable) tones for DFCW. The TX can be controlled through the serial or the parallel port; the pins used for PTT and KEY are the same used also in other digital modes programs (and also the same as in Rik Strobbe QRS), i.e. RTS = key and DTR = PTT/DFCW when using the serial port, DB0 = key, DB1 = PTT/DFCW when using the parallel port.

Many of us have been hoping for good conditions for some time now. HF conditions are awful at the moment with aurora after aurora, but I guess you never know on LF.

Sorry that I'm not quite ready to listen yet.  I've downloaded and installed Argo, and have ordered a Wellbrook LFL1010 active loop antenna, but the loop has not arrived as yet.  After it's arrived and installed, I should be much better able to hear LF signals.  So far, on CW with a short wire, I've copied 189 khz beacons out to 50 miles or so.  I haven't tried QRSS yet.  Because the 386 computer in my shack won't run Argo, I would have to tape-record the signals and then play them into this one.  I think I'll try that after the loop is installed.

Have a good weekend.

73,

The RSGB HF convention is being held in Windsor 20 miles west of London this weekend.

The usual 136kHz demonstration station is being set up and should be operational by 17.00 UTC Friday. Hopefully the new location for the convention will have lower background noise level and this year we will have better reception of the stations trying to work GB4RS.

We will be able to operate CW and QRSS. If you hear us on over the weekend, please call and say hello.

As I appear to have left booking my Saturday evening dinner ticket far too late, I will be free to operate from 18.00 to 24.00 Saturday.
For the last 4 hours I will transmit QRSS on 137.710 kHz
As 250mW ERP has made it across the Atlantic under good conditions.....It may be worth listening.

TX will be 800 W  to T antenna  apx 60 feet high with 100 foot top section.

Ever since a few of us became active from north of Tannahill Gorge and you are just north of it like G3YXM/G3KEV/MM0ALM and a couple of others there has been virtually a total silence south of the Gorge, especially to the South East. Rumour has it that the competition has got too much even the Decca Jeeps were not as magical as first thought. I hope you manage to get on during the winter period I need some competition !!!!! especially for the Transatlantic tests. I am also trying to encourage MM0ALM to fire up, plus a couple of GI stations with suitable antennas. de Mal/G3KEV From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 23467 invoked from network); 10 Oct 2002 14:06:34 -0000 Received: from murphys.services.quay.plus.net (212.159.14.225) by mailstore with SMTP; 10 Oct 2002 14:06:34 -0000 Received: (qmail 11995 invoked from network); 10 Oct 2002 14:05:54 -0000 Received: from post.thorcom.com (193.82.116.70) by murphys.services.quay.plus.net with SMTP; 10 Oct 2002 14:05:54 -0000 X-SQ: A Received: from majordom by post.thorcom.com with local (Exim 4.10) id 17zduV-0001jT-00 for rsgb_lf_group-outgoing@blacksheep.org; Thu, 10 Oct 2002 15:03:31 +0100 Received: from [62.253.164.43] (helo=mta3-svc.business.ntl.com) by post.thorcom.com with esmtp (Exim 4.10) id 17zduV-0001jK-00 for rsgb_lf_group@blacksheep.org; Thu, 10 Oct 2002 15:03:31 +0100 Received: from l8p8y6 ([62.252.209.45]) by mta3-svc.business.ntl.com (InterMail vM.4.01.03.27 201-229-121-127-20010626) with SMTP id <20021010140329.QBRC15439.mta3-svc.business.ntl.com@l8p8y6> for ; Thu, 10 Oct 2002 15:03:29 +0100 Message-ID: <000301c2705d$6b88ebc0$2dd1fc3e@l8p8y6> From: "hamilton mal" To: rsgb_lf_group@blacksheep.org Date: Thu, 10 Oct 2002 09:46:54 +0100 MIME-Version: 1.0 X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.50.4807.1700 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Subject: LF: EARS Content-Type: text/html; charset=windows-1252 X-Spam-Status: No, hits=1.3 required=5.0tests=DATE_IN_PAST_03_06,SPAM_PHRASE_00_01,USER_AGENT_OEversion=2.42 X-Spam-Level: * Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Content-transfer-encoding: 8bit

I > wonder what could have happened to him? Do you miss me Jim ? If you give up on LF that would be the end for England. I think you are the only one left flying the flag. Dont forget we had a recent QSO when I was over in Tyrone/GI3KEV. I had the station on air for 3 weeks and only heard/worked about 3 stations. Big change from a couple of years ago, then it was pileups galore. I also work HF when over there and that has never changed. When I fire up especially on CW I find it difficult to get away because of the demand for Tyrone/Ireland for the different certificates and awards being collected. I usually work about 50 one after the other dx fashion then have a break to let the KEY cool down !!!!! I could do with a QSL manager, especially if I move over there. The LF rig here is fully operational, but I have worked everybody a dozen times over and am waiting for some new countries to emerge and Uncle Sam to fire up!! 73 de Mal/G3KEV > > Cheers, Jim Moritz > 73 de M0BMU > > From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 29239 invoked from network); 10 Oct 2002 12:44:55 -0000 Received: from warrior.services.quay.plus.net (212.159.14.227) by mailstore with SMTP; 10 Oct 2002 12:44:55 -0000 Received: (qmail 20566 invoked from network); 10 Oct 2002 12:44:17 -0000 X-MSMail-Priority: Normal Received: from post.thorcom.com (193.82.116.70) by warrior.services.quay.plus.net with SMTP; 10 Oct 2002 12:44:17 -0000 Received: from majordom by post.thorcom.com with local (Exim 4.10) id 17zcaP-0001Vm-00 for rsgb_lf_group-outgoing@blacksheep.org; Thu, 10 Oct 2002 13:38:41 +0100 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from [80.68.3.204] (helo=relay.dx.ru) by post.thorcom.com with smtp (Exim 4.10) id 17zcaM-0001Vd-00 for rsgb_lf_group@blacksheep.org; Thu, 10 Oct 2002 13:38:39 +0100 Received: (qmail 41629 invoked from network); 10 Oct 2002 16:38:34 +0400 Received: from ed.dx (10.0.1.11) by gw.dx with SMTP; 10 Oct 2002 16:38:34 +0400 Date: Thu, 10 Oct 2002 16:39:05 +0300 From: "Ed Lesnichy" X-Mailer: The Bat!

I think that: Rrad = 1600*(H effective/lamb)^2= 1600*(80...100/2200)^2=2...3 Ohm P = I^2*Rrad=2.5^2*(2...3)=12.5...18.75w ERP but the aerial is close located to a metal mast... but...but... but Poutput=40..50w 73!

This would result in an ERP of about 35 to 45 watts with 2.5 amp of aerial current. So it is not surprising that he did not hear many of the calling stations who were probably at least 20dB weaker. Maybe someone with the right software could get a better estimate for the aerial. All in all , a good effort and it certainly raised activity levels that weekend.

Our report of Sep 26-29 UA6-activity. As almost all these days there was a rain with thunder-storms (very high local QRN), we basically carried out beacon-tests with the purposes of attraction of interest to 136 in exUSSR and finding-out of propagation on LF. OUR EQ:::::::::: ANT TX - Big Vertical (see atach) PA - audio lamp PA (up to 100w output - license limit), but we held all time a current about 2,5A in the aerial (abt 16V Output voltage PA). Settlement ERP abt 10-15w (at Output abt 40-50w) TS-850 with ATT + Band Pass filter (with high Q coils) ANT RX - Beverage @2m, 640m long to EU REPORTS::::::::::: We have received a lot of excellent files of our signal from UA1(1 HAM), UA3(6), UR-Ukraine(4) and many from Eu Most pleasant for us were files from Jose EA1PX(3662km) and Alex RA9MB (2510km and first Eu - Asia reception on 136??) Our signal accepted not only in night time, but also day on distance about 1000-2000km (in QRSS3) Interesting statistics: under the reports from ex USSR, almost all accepted our signal on Kenwoods(850, 870, 450) and on HF ANT - not special ANT for 136 Because of human errors it was not possible to us beacon-tests with VK/ZL(3 ZLs and 1 VK LF listeners) and NA (2 USA-reports) TNX by all for the reports and support. Still interesting supervision: When the short-term(15-30 min) rain began, in 5-15 minutes the current in the aerial grew with 2,5 up to 2,7..3A ! But after ending a rain a current in 20-30 min came back again up to 2,5 A. Variometer I arranged at change of a current on a maximum . Temperature of air was about 10 - 15 degrees C. I believe that the conductivity of ground was improved and then came back to former at evaporation of water from a surface of ground. Under the messages, acting to me, a little exUSSR HAMs can appear in a season 02-03 and on TX (UA3, UA6, YL(Latvia) ES(Estonia), UA2(Kaliningradsk), EU(Belarus). Some will begin preparation after CQ WW (SSB - ending Oct, CW - ending Nov) Also me have informed, that the opportunity of the sanction to HAMs of Ukraine is now considered to use 136 band. Ukraine is in CEPT, but the UR-administratives initially have not given a band 136 KHZ We assume to carry out the following beacon-test in November. 73!

Texas has been mentioned recently, its a big state and big ranches and some big radio amateur signals but not a patch on the California Kilowatt amateurs. Over the years they have been emitting probably the biggest signals from the USA.
I was a guest of W6AM and his friends some years ago and his station and his friends stations rivalled some commercial installations, and even better. The only other place where I have seen similar installations are in GI (Northern Ireland) some large antenna masts are visible on the sky line especially West of the Bann. (river bann) again the radio shacks are equipped more like commercial stations and possibly better.
I dont know anyone that is active on HF over there with a tower less than 60 ft high and most are at least double that height. I get over there frequently and know most of them but they are not interested in 73 or 136 khz so in the meantime its only GI3KEV/P. One other that was active has gone QRT, likewise the only station in Scotland and a couple in Wales have also gone QRT, that leaves only a few English stations still on air in the UK.
Hardly encouraging news on the LF scene, the same seems to apply to EU. The only acty I hear these days is from PA, DL and occassionally the odd ON, F and SM pops up.
Considering that I worked 23 countries a couple of years ago LF is certainly in decline, and no new countries seem to be emerging, apart from the odd weekend Russian station.

At times I disagree with others if I think they are wrong or missing the point. Usually we can all learn something from another persons experiences. My loop is parallel resonant and matched at the feed point of the loop to 50 ohms, which as you say is the correct place for the matching. Some use the matching network at the shack end for convenience and it works but not the correct place in my opinion. I have not yet tried series resonating the loop as you suggest but will try this when I get time I know the technique with the capicators and the matching transformer. As you suggest lowering the power level because of the capacitor voltage limitations and checking the loop against the vertical would be a realastic comparison. Having gone to all the trouble building a rig to generate the necessary power in conjunction with my vertical to give 1W erp it would defeat the object by reducing the power to accommodate the loop. Even if I could get capacitors to handle the voltage on the loop the current would be colossal for 1W erp, someone in the past calculated 40-50 amps RF, whereas with my vertical it is only around 5 amps or less and manageable. The permitted operating power and antenna limitations on LF at present in the USA suits experimenting with loops but when you hopefully get something similar to the UK/EU power levels then antenna requirements would need a rethink, and the best approach is the vertical under normal circumstances. (Think ZL is 5W erp) I could realistically get a larger loop up and firing E/W like the present loop on LF and when I get time in the future might try this. This would keep the RF amps down. One other point is location and space for some, and since amateur radio antenna situation is a no choice approach often, then what works for one does not work so well for another. I am not keen on the big RF amps for small loops, and dont want to set the UK on fire !!!!! however small loops on RX are a different story and suit some because of environmental noise, especially rotatable types also the convenient size. I suppose everything has a use on earth. I would like to hear/see some LF signals soon from your direction, all ready this end just waiting for the smoke!! 73 de Mal/G3KEV From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 11741 invoked from network); 9 Oct 2002 17:08:01 -0000 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit Received: from murphys.services.quay.plus.net (212.159.14.225) by mailstore with SMTP; 9 Oct 2002 17:08:01 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: (qmail 9179 invoked from network); 9 Oct 2002 17:08:13 -0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from post.thorcom.com (193.82.116.70) by murphys.services.quay.plus.net with SMTP; 9 Oct 2002 17:08:13 -0000 X-SQ: A Received: from majordom by post.thorcom.com with local (Exim 4.10) id 17zKDl-0007Os-00 for rsgb_lf_group-outgoing@blacksheep.org; Wed, 09 Oct 2002 18:02:05 +0100 Received: from [194.217.242.80] (helo=anchor-post-39.mail.demon.net) by post.thorcom.com with esmtp (Exim 4.10) id 17zKDl-0007Oj-00 for rsgb_lf_group@blacksheep.org; Wed, 09 Oct 2002 18:02:05 +0100 Received: from telemetry.demon.co.uk ([194.222.19.114]) by anchor-post-39.mail.demon.net with esmtp (Exim 3.36 #2) id 17zKDj-0004WE-0U for rsgb_lf_group@blacksheep.org; Wed, 09 Oct 2002 18:02:03 +0100 Message-ID: <+N1p07A8CGp9MwyG@telemetry.demon.co.uk> Date: Wed, 9 Oct 2002 18:00:44 +0100 To: "RSGB LF Group" From: "Tom Boucher" MIME-Version: 1.0 X-Mailer: Turnpike Integrated Version 5.01 U Subject: LF: R6BWO & DL1EIE X-Spam-Status: No, hits=1.3 required=5.0tests=SPAM_PHRASE_00_01,SUBJ_ALL_CAPSversion=2.42 X-Spam-Level: * Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Ref. new stations R6BWO and DL1EIE on 136: My theory is that the missing dot in Jeff F6BWO's call sign got mysteriously delayed and re-appeared in that of DL9IE!

That would give us guys some idea of how a real big loop works. See my web page for an idea of a Loop Tuner Box. It shows the transformer and caps so you can get an idea of what Bill is describing to you. I thing high voltage Door Knob caps would work for resonating the loop wire to 136kc. You should be able to use one of those Phillips ferrite cores for a transformer. Please don't be offended by any of the US guy's comments.

Subject: LF: RE: Lasso alias loop

Hello Mal,

 

What size and type of wire do you use in your loop??? Do you know the AC resistance of the loop??? These are very important parameters, as Wild Bill would point out. Maybe your loop has a very high Rac and this is why it performs poorer than your huge vertical. Anyhow, let us know the wire size and such and we can understand a bit more what you are using.

Thanks es 73’s,

Hi Mike and all

 

My loop uses the same wire as the vertical antenna and radials. I use multi strand 2.5 mm insulated electrical wire.

The loop is vertical and the top wire is up abt 70 ft and its natural resonant freq is 90 metres.

It is about 20 db down on my vertical array on 136 khz.

The loop is a good size by any standard but small relative to the frequency of 136 khz.

If I went to a lot of trouble and used 3mm litz the RAC might improve but not substantially and would not catch up on my vertical.

I understand that under some circumstances like living on a small city lot, or having a poor earth beneath the qth then maybe the only alternative to a vertical would be a loop but does a loop not take up a lot more space than a vertical.

In my opinion if you want a big potent signal on LF then the only antenna is a vertical configurated system. If you do not have the real estate for such an antenna then you cannot do it, and will have to make do with what ever you have.

I have worked quite a lot of stations around EU and those using verticals are away above the loops by a big margin.

For anyone that is serious about LF then you need the acreage for the antennas to make an impression. If you just want fun then try anything and hope for the best.

Having been interested in radio long before I reached my teens and got a licence in my teenage years and was brough up in the countryside I always had the antenna space and have always bought a suitable property for amateur radio purposes.

When I lived in Hongkong/VS6HI I made sure that I picked a property with about an acre for amateur radio acty in the New Territories and the same when I lived in Singapore 9V1OY. 

Not interested in town or city lots - no good for amateur radio.

Subject: LF: Lasso alias loop

 

What us folks in the UK and Europe must remember is, that the USA boys are biased towards loops(lassos). They were brought up on the ranches lassoing cattle and naturally when it comes to radio this is the way they think, and its hard to convince them otherwise.

Although my 90 metre loop (natural resonance) is good it is not a patch on my vertical system.

The loop also has the disadvantage of being bi-directional, whereas the vertical captures signals from all directions.

I find on receive the loop is well down in its favourite direction from the vertical and on transmit poor.

I am not exactly comparing like with like because the loop is 90 metres and well elevated, but my vertical is well over 100 ft and supports 3 x inv L antennas each one 100ft plus, vertical and at least 300 ft horiz. Total inductive base loading is less than 0.5 mh on 136 khz. I intend to improve on this configuration when I get the time. The ground system consists of several 300 ft plus insulated radials. Both the vertical and loop are matched to 50 ohms and fed with 50 ohm cable to the shack where all the equipment is designed for 50 ohms.The antennas and base feed are some hundreds of feet away from the shack, away from any possible domestic electrical noise.

I think the roundup days are over in America and they ought to try some verticals on LF

The next steamer leaving Belfast for Baltimore/Philadelphia is in 3 weeks time and I might send over some verticals. This service has been operating since 1823 and is reliable, still using sails.

I hope that the 'jabbing' going on between die-hard vertical and loop users relative to the advantages of either antenna is not taken seriously by anyone since it is (at least to most of us) just part of the fun in LF communicating. The qth.net reflector is loaded with this type of humor and in fact the 'loop guys', 'loopers', or are whatever, are continually jabbing at each other. Hope the interest in LF over there perks up once the winter season is in full swing!

It is of course an advantage to switch between 20Hz and 2kHz bandwidth, but the instrument you pick doesn't need to cover far above 136kHz Have documents for many different Pegelmesser/Selective Level Meters made by Siemens and Wandel&Goltermann, some is donated to NRHF (www.nrhf.no) Some older instruments uses valves, but usually it is not many different, use of C3m or CCa (E88CC) throughout the instrument is quite common, also few other types 73 Jan-Martin LA8AK http://www.laud.no/la6nca/la8ak/ -----Opprinnelig melding----- Fra: WE0H [mailto:we0h@core.com] Sendt: 8. oktober 2002 01:33 Til: rsgb_lf_group@blacksheep.org Emne: LF: RE: SPM14?

Actually under 'ideal' site conditions such as an open field, free from the effect of trees, and where a good ground system can be installed, the top loaded vertical with similar overall dimensions beats the loop for radiation efficiency by 6db on average. Typical residential sites, however, are another story. In my home situation the same 6db favors the loop over the vertical - even for a #12ga loop wire. Additionally, I have found the loop is whole lot more rugged when it comes to extremes in wind, rain, ice and snow. What makes 'looping' even more fun, at least for me, is that this success stands in the face of so much negative text written about the TX loop. Renowned authors of antenna textbooks often state that the small loop (I.E.: <<1WL) is of little value for transmitting.

Hello Mal,

 

What size and type of wire do you use in your loop??? Do you know the AC resistance of the loop??? These are very important parameters, as Wild Bill would point out. Maybe your loop has a very high Rac and this is why it performs poorer than your huge vertical. Anyhow, let us know the wire size and such and we can understand a bit more what you are using.

Thanks es 73’s,

Subject: LF: Lasso alias loop

 

What us folks in the UK and Europe must remember is, that the USA boys are biased towards loops(lassos). They were brought up on the ranches lassoing cattle and naturally when it comes to radio this is the way they think, and its hard to convince them otherwise.

Although my 90 metre loop (natural resonance) is good it is not a patch on my vertical system.

The loop also has the disadvantage of being bi-directional, whereas the vertical captures signals from all directions.

I find on receive the loop is well down in its favourite direction from the vertical and on transmit poor.

I am not exactly comparing like with like because the loop is 90 metres and well elevated, but my vertical is well over 100 ft and supports 3 x inv L antennas each one 100ft plus, vertical and at least 300 ft horiz. Total inductive base loading is less than 0.5 mh on 136 khz. I intend to improve on this configuration when I get the time. The ground system consists of several 300 ft plus insulated radials. Both the vertical and loop are matched to 50 ohms and fed with 50 ohm cable to the shack where all the equipment is designed for 50 ohms.The antennas and base feed are some hundreds of feet away from the shack, away from any possible domestic electrical noise.

I think the roundup days are over in America and they ought to try some verticals on LF

The next steamer leaving Belfast for Baltimore/Philadelphia is in 3 weeks time and I might send over some verticals. This service has been operating since 1823 and is reliable, still using sails.

Hello Wil.

If you have no replies please let me know. I will be at Windsor setting up the demo station at 2.30. It's about 30 minutes to Heathrow. Should be able to make it if no-one else is passing at that time.
I assume you are arriving at terminal 2.

The antenna was actually a vertical which is still by far the most popular configuration over here.

Both the vertical and loop are matched to 50 ohms and fed with 50 ohm cable to the shack where all the equipment is designed for 50 ohms.The antennas and base feed are some hundreds of feet away from the shack, away from any possible domestic electrical noise.
I think the roundup days are over in America and they ought to try some verticals on LF
The next steamer leaving Belfast for Baltimore/Philadelphia is in 3 weeks time and I might send over some verticals. This service has been operating since 1823 and is reliable, still using sails.

Actually under 'ideal' site conditions such as an open field, free from the effect of trees, and where a good ground system can be installed, the top loaded vertical with similar overall dimensions beats the loop for radiation efficiency by 6db on average. Typical residential sites, however, are another story. In my home situation the same 6db favors the loop over the vertical - even for a #12ga loop wire. Additionally, I have found the loop is whole lot more rugged when it comes to extremes in wind, rain, ice and snow. What makes 'looping' even more fun, at least for me, is that this success stands in the face of so much negative text written about the TX loop. Renowned authors of antenna textbooks often state that the small loop (I.E.: <<1WL) is of little value for transmitting.

I remain to be convinced about the benefits of loop TX antennas - a lot of any advantage to US Lowfers seems to be due to interpretation of the "part 15" regulations with regard to antennas - if you have the choice of a tuned wire 15m long in total , or a 15m by 15m loop, it is not surprising that the latter is a better bet - it is a much bigger antenna, after all. This choice does not apply on 136k. From a practical point of view, where most peoples' best available antenna is restricted by the number and height of supports that can be used, and the planning permission difficulties they cause, it is much more difficult to keep all that litz wire in the air, rather than have a skinny wire aerial, and keep the litz wrapped round the dustbin!

Some one has suggested publishing acty times and other info via the RSGB magazine Rad Com.
Most LF operators and SWL's that I know both in the UK , around EU and the rest of the world do not get this magazine because they are not members.
The best solution is to publish the info via the various EMAIL outlets, or take pot luck.
I will be in GI/TYRONE in a couple of weeks time and if there was sufficient interest I could be active as GI3KEV on both 136 and 73 khz.

I now have the facilities to work cross-band HF/LF, so I could certainly do this - allthough reception on 80m is poor at my QTH due indirectly to the Brookmans Park broadcast transmitters. 40m is OK, so is 20m, on which I had an X-band QSO with EA1PX (using QRSS on LF) not long ago, so this is certainly a practical proposition. >2) One morning each month to be devoted to 73kHz activity, with listener >reports.

I think the last point is very important - most amateurs probably are not aware of what is happening on LF. So to reach a large number of potential new listeners, these types of event would need widely-circulated advance publicity - perhaps in the news pages of RadCom for example. For my own part, due to work commitments I am unlikely to be doing a vast amount of LF experimental work and operating this winter - but spending a few hours here and there on this type of event would not be a problem. Hope to see everyone down at Windsor next week, Cheers, Jim Moritz 73 de M0BMU From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 10320 invoked from network); 6 Oct 2002 13:46:02 -0000 Received: from murphys.services.quay.plus.net (212.159.14.225) by mailstore with SMTP; 6 Oct 2002 13:46:02 -0000 Content-Transfer-Encoding: 8bit Received: (qmail 18870 invoked from network); 6 Oct 2002 13:46:09 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from post.thorcom.com (193.82.116.70) by murphys.services.quay.plus.net with SMTP; 6 Oct 2002 13:46:09 -0000 X-SQ: A X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from majordom by post.thorcom.com with local (Exim 4.10) id 17yBj0-0006pk-00 for rsgb_lf_group-outgoing@blacksheep.org; Sun, 06 Oct 2002 14:45:38 +0100 Received: from [147.197.200.9] (helo=hestia.herts.ac.uk) by post.thorcom.com with esmtp (Exim 4.10) id 17yBiz-0006pa-00 for rsgb_lf_group@blacksheep.org; Sun, 06 Oct 2002 14:45:38 +0100 Received: from gemini ([147.197.200.44] helo=gemini.herts.ac.uk) by hestia.herts.ac.uk with esmtp (Exim 3.22 #1) id 17yBiV-0007Rz-00 for rsgb_lf_group@blacksheep.org; Sun, 06 Oct 2002 14:45:07 +0100 Received: from [147.197.232.252] (helo=rsch-15.herts.ac.uk) by gemini.herts.ac.uk with esmtp (Exim 3.33 #1) id 17yBiK-0003Mr-00 for rsgb_lf_group@blacksheep.org; Sun, 06 Oct 2002 14:44:56 +0100 Message-ID: <5.1.0.14.0.20021006143430.00ade750@gemini.herts.ac.uk> X-Sender: mj9ar@gemini.herts.ac.uk X-Mailer: QUALCOMM Windows Eudora Version 5.1 Date: Sun, 06 Oct 2002 14:44:51 +0100 To: rsgb_lf_group@blacksheep.org From: "James Moritz" In-reply-to: <000f01c26d14$5f185980$3a567ad5@jackie> References: MIME-Version: 1.0 X-MailScanner: No Virus detected Subject: Re: LF: 136 beacon Content-Type: text/plain; charset=us-ascii; format=flowed X-Spam-Status: No, hits=-4.1 required=5.0tests=IN_REP_TO,DEAR_SOMEBODYversion=2.31 Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Dear Steve, LF Group, At 09:42 06/10/2002 +0100, you wrote: >Yesterday evening and this morning I'm getting a keyed beacon at about >136kHz, just below the level wher my ears or the computer can decode it.

My favorite explanation is that these are harmonics of telecomms clock signals on 8kHz, being radiated by phone wires, etc - there are different signal components present in different locations. So this could well be a form of fairly local QRM rather than a receiver problem or an intermod. I also hear something similar on 72kHz when Rugby is QRT.

Thanks, Mike. I was rapidly coming to that conclusion, I'll have to check the receiver out. With the front end filtering I have and the signals I see out of band, I hadn't expected any intermods.

Hi All
Some stores have a variety of buckets/baskets varying in diameter from a few inches to 15 inches and depth up to 15 inches or more. These devices are sturdy and slotted or at least 50% cut out making good semi air spaced coil formers for LF, much more efficient than any solid plastic type former. These baskets can also be stacked and used in series for those that need more inductance.
The smaller ones fit inside the larger ones and make good variometers.
I got mine from the Ł stretcher shop for 90 pence each !!!! There are various colours but I use white when possible and so far no melt down or signs of distortion due to high RF voltages.
They make a tidy job, look good.
For insulators that will withstand high RF voltages and only cost a few pence use crab/lobster pot spinners, these are white plastic material, figure of 8 construction and strong about 4 inches long and 1-1/2 inches wide. These are available from ships chandlers at fishing ports and cost about 50 pence each, also in the same shops there are a variety of marine plastic ropes any diameter and up to 200 metres in length, ideal for antenna support work.
 
Antenna wire is available from electrical shops on industrial estates at reasonable prices usually in 100 - 200 metre rolls.  I use insulated wire, various colours and usually 2.5 mm stranded although 1.5 mm up to 10 mm is usually available. This wire also makes good  insulated ground radials
 
Everything that a LF experimenter needs is readily available and at the right price!!!
 
When you get tired of LF you will have enough wire to go into the electrical wiring business, enough lobster pot spinners and baskets to go fishing and enough rope to hang everyone that took a dislike to you while LFing.

Unfortunately the PC crashed at just before 1000z when attempting another upload. This may have been because I was trying ro run a virus checker. Identified whilst I was listening (0800z to about 1000z) were DL1EIE,F6BWO,PA0BWL,DK7SU (working Wil) M0BMU DL3FDO all plainly seen on the captured screen. Three other weak station could be seen but not heard before a TV came on. There was also a couple of QRSS3 stations one may have been Markus DF6NM but the waterfall is too slow for decode. There were also two other weaker stations that were on at the time Jim was working DL3FDO and he was chopping the filter up a bit making copy difficult. I have included a time/date stamp at the bottom now so you know when the last screen was collected. The clock was set against NPL at 1000z (1100 BST) and was 30 secs slow. Not many other Gs !! Maybe I got up too late !

I also have a number of lengths of "pipe" or various diameters (and colours) and some epoxy / glass-fibre "thruster tunnel" offcuts (only the yachties will know what those are!) but they are about 9in diameter. I also have a number of white plastic buckets about 12-13in diameter, and a fair number of odd pieces of 'plastic' , mainly off cuts (will make aerial insulators, or float the whole PA heat-sink and avoid mica washers ) also broken windshield from speedboats and cruisers (long but about 10in wide 3/8th in. thick). I will load the boot up with as much as I can carry and please stop me and collect if you want any of it. First come first served...... so dont miss out !!

The beacon of IK2DED was clearly seen with a little loop antenna 2 meters over the ground inside the yard. Many visitors don't beleved that it's possible to see some signals also with poor antenna. The major difficulty, they said, is that in Italy is very difficult to see sone signals. Local signals can help a lot the newcomers.

LF is booming for us guys in the US. It never let up all summer and there are many new operators building stations lately. This should be a busy winter for the US LF operators.

 

    Hello Mike,

Glad to hear that LF is booming your side of the Ocean hi, it seems to have got submerged this side !!!

SM6BHZ calling CQ a short time ago on 136.5 khz RST 599, very strong signal and no one responding. It appears most have lost interest in LF compared to a couple of years ago.

73 khz is never mentioned these days although there is an abundance of operators with NOV'S

at the present time and only one year left for action. 136 khz acty is also very poor and hardly worth the effort. There seems to be a very low up take around EU to engage in 136 in spite of the fact that the band has been going for a number of years.

Listen on 1.8 khz  and up and the bands are more active than ever, it is difficult to find a slot on either CW or SSB plus all the other modes plugging away.

Hello Mike / group.

Given that most newcomers would probably listen to the bands first before committing time and effort to constructing equipment, then I think activity days and working crossband is an excellent idea.

It should be quite easy to publicise something like 'last Sunday in the month' etc. together with an idea of times. It's just a question for LF op's to circle the dates on their calendars and remember to come on and listen on HF if that's possible.

Great idea.

I understand that the RSGB have tentatively scheduled a 136kHz TX design for publication in the Jan / Feb issue of Rad Com.
It maybe that a 'chunk' of Rad Com covering an LF topic will encourage more readers  to Dave's (G3YXM) LF column. - A good opportunity to publicise activity days.

Hope to see you all next weekend for HF convention at Windsor where the LF demo station will be in action once again.

There is some activity every weekend. In half an hour this morning, I heard three new calls: DL9EIE (I had a partial QSO), F6CHT and DK7SA? (neither replied to my call) and I made a QRSS3 CQ. However, there is an increase whenever something interesting happens, such as an expedition - the most recent being a lot of QRSS activity connected with the UA6 expedition. It is necessary to generate local activity so that new listeners have something strong to hear, and DX activity so that experienced operators have something interesting to work. It is also important to activate 73kHz in its final year. I suggest the following for the 2002-2003 winter season: 1) One day / weekend each month to be devoted to crossband with HF (3.5/7MHz). 2) One morning each month to be devoted to 73kHz activity, with listener reports. 3) Two dates (in December and February?) to be called LF Field Days, where portable operation (or operation from the QTHs of non-LF operators) is encouraged. 4) Two dates to be devoted to 73kHz crossband activity (QSX 136kHz or 3.5/7). 5) Local QSOs to be encouraged by a competition (probably just for fun) where operators try to work stations whose callsign ends with each of the 26 letters of the alphabet (G3MBA, ON6VB, F5CDC . . . GW4KDZ). This should allow quite small stations to be very popular with competitors and might lead to people being encouraged to come on the band. The competition to last from 1 December to 30 April. I stole this idea from another amateur radio group, I think it was QRP. The advantage or using the last letter is that everyone is potentially an exotic station. 6) All of the following to be publicised in AR magazines, newsgroups, etc, to ensure maximum support from inside and outside the LF community. Any thoughts?

This involved much digging and dust, and a day without being able to flush the toilet. That was the Bad News. The Good News was that I persuaded the workmen to hammer an earth stake into the bottom of the large hole they dug. This has increased my antenna current slightly, improved incoming signals and reduced local noise. The other Good News is they gave me the offcuts of drain piping for use as coil formers (I don't know whether they believed me!). I have about 3m of 110mm pipe, orange in colour and very strong - the wall is about 3mm thick. I will have this with me at the HF (LF) Convention next Saturday for anyone who wants a piece. Unless anyone requests a specific length within the next few days(the longest piece is 2m), I will cut the pipe into convenient lengths of about 150mm.

LF is booming for us guys in the US. It never let up all summer and there are many new operators building stations lately. This should be a busy winter for the US LF operators.

Subject: LF: SM6BHZ

 

SM6BHZ calling CQ a short time ago on 136.5 khz RST 599, very strong signal and no one responding. It appears most have lost interest in LF compared to a couple of years ago.

73 khz is never mentioned these days although there is an abundance of operators with NOV'S

at the present time and only one year left for action. 136 khz acty is also very poor and hardly worth the effort. There seems to be a very low up take around EU to engage in 136 in spite of the fact that the band has been going for a number of years.

Listen on 1.8 khz  and up and the bands are more active than ever, it is difficult to find a slot on either CW or SSB plus all the other modes plugging away.

Thanks to assistance from John W1TAG. The waterfall is a Spectran display showing 137.8 to 136.1 (backwards as its in lower sideband) There are some problems to be sorted out yet. 1 It will not automatically refresh when a new image is uploaded, once you have downloaded the first page.....I need a wizz bit of HTML here I believe....so you will have to use the refresh button occasionally 2. My location is not marvellous as regards noise, so I do get wiped out occassionally, in those cases I will probably be running with integation to average out the noise, and fewer updates. 3 I also have to sort out some of the dialling properties if it ever to run 'unattended' , so that it will automatically dial my site if the line has become disconnected. At present I initiate a dial-up and sit and watch it !! 4 I dont want to get black-listed by my ISP too quickly, so it will be run occasionally, when there is likely to be activity, or on request for anyone that wants to play ...er I mean experiment, particularly at times when there is no one to work. 5 Several things I havent discovered yet !! It will be difficult to decide what strength the signal is from the display (unless the carrier is still running at the point of capture in which case the upper trace will give a level.) but in future it may be possibe to use Wolf's SpectrumLab to upload a signal level reading in a narrow band of frequencies as Brian does when collecting his plots. Argo could also be run for displays of QRSS signals. Anyone interested?? My telephone number is available to those who might require it, but on a direct e-mail. The page can be accessed directly http://www.alan.melia.btinternet.co.uk/periodic.htm or is linked from my contents page (I hope the links work properly !) If the time is more than about 5 minutes behind UK time it is an old plot....there is no date on the screen I notice. Like a stopped clock, it will look right once a day !

An ordinary mike/loudspeaker setup is not ideal when one has come up for air and is still wearing a full diving outfit. One of the divers has seen a bone microphone/loudspeaker which belongs to Derbyshire Cave Rescue Organisation and wonders if it would be suitable for use with the Heyphone. To check this out I need such a microphone, but cannot borrow the Derbyshire one as to do so might compromise their readiness. The unit is known locally as a Talking Rope and is believed to be of army surplus origin. I understand that it does appear to have a stores code, but this is on a little rubber sheath on the cable and is so perished as to be virtually indecipherable. The best guess is:- APP?78 147928 but the only certain reading is AP???8 ??79??. Can anyone identified this unit please?

In a recent message it said VA3LK had gone QRT on LF.
I have never heard this station active on LF although I have worked quite a number of VE and W staitions xband and received numerous email reports via this reflector about my signal, and seen during daytime by W4DEX on 136 khz.
I have heard this station only on 7mhz the odd time on cw while I was working xband on 7025 khz.
but he did not seem to hear me or the other VE/W stations working xband !!!!!!
Maybe his antenna was choked up with snow and ice but he seemed to be calling CQ a lot of the time on 7025 Khz, I expect this was a coincidence!!!!

thanks for your helpful hints. I got the solution from Arie. Guess he is the programmer of this phantastic SW! Now its running without any problems. Did forget to register the OCX-file.

Here are the right steps given by Arie:

Please try the following:

- copy the msflxgrd.ocx to C:windowssystem32
- go to the start menu, click Run and enter:
REGSVR32.EXE C:Windowssystem32msflxgrd.ocx
- give <Enter>, this should register your OCX file.
- try again and let me know how you got along.

Now I'll try to edit the nec-file for my marconi. To output a drawing of the nearfieldspots is one of the very useful features. I need these characteristics for some documents in order to give them to our administration.

Well a very novel idea has come forward, demodulate a continuous carrier signal with TWO demodulators, one looking for ARGO like signals and the other process identifying anything say longer than 20 Milliseconds for Meteor Burst or other short duration type of signals. This has excellent potential to identify a propagation mechanism that might be a candidate for exploration further a TransAtlantic III QSO.

I have the extensions turned on in the folder options, so things like this show up better. If you have them hidden it looks just like a .doc file. I also read a lot mail in Outlook Express by first right clicking the message in the "in-box", then selecting "propeties" at the bottom of the menu, Then selecting the "details" tab, and finally pressing the "message source" button which is near the bottom. This allows you to inspect the contents of an E-mail, and read the text, without "reading" it as such. The program makes no attempt to decode attachments or display pictures etc. it is just the raw text that you see, complete with all header information. Also, I don't know whether you realise that you can just drag an E-mail out of Outlook Express and drop it into an Explorer window. This creates a file with a .eml extention, but you can rename it to a .txt and then examine it with your favourite dos text editor ( I'm so old fashioned !). I use this to manually "quarantine" messages. Forgive me if I'm teaching Grandmother to suck eggs here (English idomatic expression) but it was an eye-opener to some of my collegues at work. 73 and thanks once again for the warning Hugh M0WYE ----- Original Message ----- From: "Alberto di Bene" To: Sent: Wednesday, October 02, 2002 6:44 PM Subject: Re: LF: Dont open "Larry Kayer" msg VIRUS > Andrew Nunn wrote: > > > Hi all, > > > > I received a message purporting to come from a member of this list at > > 15.24 today.

The problem is that most of the world seems to use Outlook and todays experience seems to indicate they are spreading this rubbish like there's no tomorrow. I have seen the light, unfortunately you will never convince the rest of the world. I have Linux on my machine (dual boot) but rarely use it. Some of my essential business software is only available for Windows. So I have to use WIndows for most of my work, but use virtually nothing else from the MS camp (Opera for browsing, Pegasus for email, Star Office for documents). ps.

From: "Larry Kayser" and you can be assured that I have nothing to do with rftechnology.co.uk hi. I abandoned MS Outlook some time ago because it caused so much trouble but now I am getting an average of 25 or more Viagra, low rate US mortgages, and porn spam a day. I have been ignoring this for some time but I guess it is coming time to do something about it. I have been digging a lot of the Internet, looking for information and this seems to cause more and more spam. I do have two separate processes running here now. I have a special RS-232 adapter on my MODEM connection and I have two separate processes continuously catching the incoming and outgoing data into files, these tell me what has come in and gone out from this machine. One thing, if your using the "unregistered" versions of much of the current software, there are massive amounts of advertising files down loaded into your machine ever few days. I have another process running that is triggered from the incoming files and they are erased often within moments of being delivered. >I hope you are keeping well, and enjoying life?? Yes, I am well, overworked as usual but doing well really. My LF gear has now been sold and my LF days are over now. It was fun, but trying to keep a significant antenna up was more than I could cope with and certainly to much after my car accident last December 10th. So those days are over. I watch this reflector for DSP things. I am now dedicating a lot of effort on the LDE research and also on working up a technology to do the North Atlantic again but this time on 144 MHz. Both items need the same generic software so I am now focusing only on the software issue from this end. My work involves the collection of massive amounts of .WAV files and the trick is to process this stuff fast and discard the 98% or 99% of it that has nothing of interest on it. As usual I am working this from a number of directions but so far I can not process more than about 6 hours of collected data per day, more and bigger computes or much smarter software is needed hi. I have hope of getting a general purpose .DLL that does DSP things. The PSK31 has such a general purpose tool available now, there are in fact two of them already, and it is wonderful. I was able to use the PSK31 .DLL to build a custom PSK31 engine using VB6 in a few days that does what I need done for monitoring a large Server on Win2K that I have deployed in VO1. I have a sense now that the next wave of things in DSP will happen with the availability of general purpose .DLL's that can be used to focus the software on a specific activity. For me, just getting rid of most of the stuff on the screen is a joy to behold. I have two small windows on my dual CRT setup here, on the left screen, and they change colour automagically when a new event is reported in the closed loop system I have setup here for testing. I live in hope of course that the end will come quickly and mercifully to the imbedded human interface and the fixed features of the current DSP programs - they are great but if you want to move to the edges, they have no hope of meeting ones needs. I am sending this to the RSGB reflector as well, I hope that others might be interested in the .DLL method of doing DSP - comments and input are welcome. PS, I rarely send emails with attachments to anyone so if there is an attachement to an email from me it is best to erase the email immediately.

There are only two ways for that file to cause damage. One way is if the recipient has HTML rendering enabled, on an e-mail client that permits the IFRAME tag to work. The code in the body of the message causes the file to execute in the background and infect the user's machine. Any e-mail client that has HTML rendering turned off (which you can do in Outlook, though "off" should really be the default), or one which does not implement the full HTML standard (Mozilla and Netscape, for example, plus the AOL e-mail client), or one which does not implement HTML at all, will only show the file as an attachment. The second way the file could cause damage, even on non-HTML-enabled e-mail clients, is if the recipient downloads it, ignores the .pif extension, and tries to open it. Then it is free to do its nefarious work. 73, John From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 9859 invoked from network); 2 Oct 2002 17:45:28 -0000 Received: from marstons.services.quay.plus.net (212.159.14.223) by mailstore with SMTP; 2 Oct 2002 17:45:28 -0000 Received: (qmail 5527 invoked by uid 10001); 2 Oct 2002 18:49:17 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from post.thorcom.com (193.82.116.70) by marstons.services.quay.plus.net with SMTP; 2 Oct 2002 18:49:16 -0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 X-SQ: A Received: from majordom by post.thorcom.com with local (Exim 4.10) id 17wnXb-0004iv-00 for rsgb_lf_group-outgoing@blacksheep.org; Wed, 02 Oct 2002 18:44:07 +0100 Received: from [165.212.11.111] (helo=cmsoutbound.mx.net) by post.thorcom.com with smtp (Exim 4.10) id 17wnXa-0004il-00 for rsgb_lf_group@blacksheep.org; Wed, 02 Oct 2002 18:44:06 +0100 Received: from uadvg129.cms.usa.net (HELO cmsoutbound.mx.net) (165.212.11.129) by cmsoutbound.mx.net with SMTP; 2 Oct 2002 17:44:00 -0000 Received: from usa.net [213.255.85.172] by uadvg129.cms.usa.net (ASMTP/dibene@usa.net) via mtad (CM.1201.1.04A) with ESMTP id 490gJBRr60400M29; Wed, 02 Oct 2002 17:43:58 GMT Message-ID: <3D9B306B.1080109@usa.net> Date: Wed, 02 Oct 2002 19:44:11 +0200 From: "Alberto di Bene" User-Agent: Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.0.1) Gecko/20020823 Netscape/7.0 X-Accept-Language: en-us, en MIME-Version: 1.0 To: rsgb_lf_group@blacksheep.org References: <5.1.0.14.0.20021002163046.024001b8@mail.btinternet.com> Subject: Re: LF: Dont open "Larry Kayer" msg VIRUS Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 8bit X-Spam-Status: No, hits=0.0 required=5.0tests=noneversion=2.31 Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Andrew Nunn wrote: > Hi all, > > I received a message purporting to come from a member of this list at > 15.24 today.

I would be grateful if someone would comment. 73, Brian At 16:10 02/10/2002 +0100, you wrote: >Hi all the message purporting to come from Larry Kayser, who is now no >longer active on LF I believe contains a very suspicious attachment...see >Dave Sargents recent posting on a new virus. >It certinaly contains all the elements, although I have not updated my >checker yet, I was suspicious of the subject line which relates to a mail >about 12 months ago.

The problem was due to the rather wide 1st IF filter in the RA1792 (about 20kHz), in combination with a fairly wide-band antenna - when tuned to 137.4kHz, all 3 signals reach the early IF stages and 2nd mixer with little attenuation, resulting in the intermodulation, allthough they are removed by the main IF filters. The solution was to add preselection with a BW of a few kHz - if the antenna is sharply resonant, this is enough to do the trick. If you are using an antenna that has relatively low Q, there are several possibilities for this type of intermodulation to appear.

I dont think it is modulated, I think the movement is slight instability. It does seem to wander about 5-6Hz. It is audible here in an SSB filter BW, reasonably strong. It is not as much 30dB here , probably 20-25dB above the 'grass' in Spectran. I can also see weak 100Hz sidebands, but an not sure whether those are 'internally generated'. I dont think so as other signals of about the same strength dont have them. There has been a signal drifting up and down for a few days. I took it to be a local source but I will look more carefully now and see if I can find out, with a loop, which direction it is in.

QRN is just wiping the band out completely but did manage to hear PA3DZ something could not stay around any longer to get the last letter. Testing on normal hand speed CW but on visual completely wiped out with the QRN. Still hard to beat a good pair of EARS. Asymetricial ears and visual are out under these conditions.

An interesting computer program for simulating antennas can be found at:

www.qsl.net/wb6tpu/swindex.html.

Just an advice to all who are having problems with the 4NEC2 program.
If, when you try to generate the output, the only thing you see is a
flashing DOS window, then nothing else happens, this is the cure :

- locate in the EXE directory of the program a DOS shortcut named 4NEC2 without extensions
- open its properties
- open the Memory tab
- in the Initial Environment combo box, make the choice 4096 instead of the default Auto
- click Apply, then Ok

Try to execute the program again, now it should work ok.

Yesterday I downloaded a different antenna simulation program - NEC4WIN95, from http://www.orionmicro.com/n4w95/n95page.html This one is a 30 day trial, but the registered version is certainly not free. I wonder how they compare. I used it successfully to simulate my 5MHz long wire (see http://www.dsergeant.btinternet.co.uk/fivemegs/fivemegs.htm). However when I tried to simulate my 136 antennas I came unstuck so perhaps Dick's program is better for this.
