I am not sure why I have such a reliable failure rate with digital circuits - I strongly suspect incompetence. It is not the case that my amplifiers oscillate and my oscillators don't. I seem to be able to make ugly construction RF and AF circuits that work first time so I was looking a solution that did not involve digital circuits. >From crystals box I found two crystals on 10489.37 and 10355.0 kHz respectively. I built two FET Colpits oscillators, firstly with a variable capacitor across the lower frequency oscillator crystal but then found that it worked best (even output across the frequency range) with the variable capacitor in series higher oscillator crystal. While trying to decided on a suitable mixer/filter I saw this e-mail from Peter DF3LP who described a very similar exciter. Peter kindly sent me a copy of his circuit (which uses 5MHz crystals) , which gave me enough ideas to complete the exciter. Apparently the first circuit of this type (that I am aware of) was built by DJ1ZB. The main attraction of this circuit is that if both oscillators are built in the same enclosure with identical components the output frequency is held constant because any drift in one oscillator is compensated for by an equivalent drift in the other. My circuit is made from junk box components and the measured drift was 137.6530kHz to start and 137.6524kHz after 3 hours. In my last e-mail I described a SCW QSO with DJ8WL (using the above exciter I might add) whos name I gave as Geri!

I found out that the old big type X-tals in the range between 5 and 9 MHZ are most suitable for use in VXO's. These x-tals give a tuning range well over a 100kC's where the small type X-tals will not tune over a range of more than 30-40kC's The coil in series with te X-tal can play tricks as far as stability is concerned. This can be observed by putting your finger near the inductor. I found out that when the VXO does not return rapidly to its original frequency i had constructed a VFO instead. I had better results when two or more inductors (range at least 1:10 in uH) are put in series, this also limits the influence of paracitic capacitance in the inductors. An other test i found out is to warm one of the x-tals with a finger and observe the drift back to the original frequency when 'cooling off'. When the original frequency is reached i am sure the X-tals have the main influence on the osc illating frequency. An other point a observed is the value to be used for the capactors dividing the voltalge in the collpits should be carefully designed. To mutch amplification makes the oscilator easy to start with a rock-solid frequency. To little amplification will not allow the circuit to oscilate at all. Sometimes a extra buffer/amplifier stage is needed to make sure the mixer works better but this does not influence stability. Good luck on LF and best 73's Mike, PA3BSH Hoogeveen, The Netherlands e-mail also to From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 13362 invoked from network); 21 Feb 1999 23:04:46 -0000 Received: from magnet.plus.net.uk (HELO magnet.force9.net) (195.166.128.26) by medusa.plus.net.uk with SMTP; 21 Feb 1999 23:04:46 -0000 Received: (qmail 4769 invoked from network); 21 Feb 1999 23:05:36 -0000 Received: from post.thorcom.com (194.75.130.70) by magnet.plus.net.uk with SMTP; 21 Feb 1999 23:05:36 -0000 Received: from troy.blacksheep.org ([194.75.183.50] ident=root) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10Ef65-0006Wj-00; Sun, 21 Feb 1999 20:03:25 +0000 Received: (from root@localhost) by troy.blacksheep.org (8.6.12/8.6.12) id PAA01369 for rsgb_lf_group-outgoing; Sat, 20 Feb 1999 15:42:58 GMT X-MSMail-Priority: Normal Received: from post.thorcom.com (root@post.unica.co.uk [194.75.183.70]) by troy.blacksheep.org (8.6.12/8.6.12) with ESMTP id PAA01282 for ; Sat, 20 Feb 1999 15:41:33 GMT Received: from man-062.dialup.zetnet.co.uk ([194.247.41.77] helo=localhost.localdomain ident=john) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10EDFX-0004Pn-00 for rsgb_lf_group@blacksheep.org; Sat, 20 Feb 1999 14:19:20 +0000 Received: (from john@localhost) by localhost.localdomain (8.9.1a/8.9.1/asi-redhat) id HAA08288 for rsgb_lf_group@blacksheep.org; Sat, 20 Feb 1999 07:19:33 -0700 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 X-Authentication-Warning: localhost.localdomain: john set sender to word.factory@zetnet.co.uk using -f Message-ID: X-Mailer: XFMail 1.3 [p0] on Linux X-Priority: 3 Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 8bit MIME-Version: 1.0 Date: Sat, 20 Feb 1999 14:16:39 -0000 (GMT) From: "John Rabson" To: rsgb_lf_group@blacksheep.org Subject: LF: PA2NJN Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org Received at RST 229 on 136 kHz at 1335UTC using a 25 turn 30cm diameter loop (resonant at 88 kHz for cave radio).

With a frequency range between 1 Hz (!) and 54 MHz (!) it is a real overkill for the LF band, but the features contained in it are excellent for what we are doing. The resolution is 1 Hz, the accuracy, once calibrated is in the same range and long time stability is excellent From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 75 invoked from network); 22 Feb 1999 02:22:46 -0000 Received: from magnet.plus.net.uk (HELO magnet.force9.net) (195.166.128.26) by medusa.plus.net.uk with SMTP; 22 Feb 1999 02:22:46 -0000 Received: (qmail 16757 invoked from network); 22 Feb 1999 02:23:38 -0000 Received: from post.thorcom.com (194.75.130.70) by magnet.plus.net.uk with SMTP; 22 Feb 1999 02:23:38 -0000 Received: from troy.blacksheep.org ([194.75.183.50] ident=root) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10El2s-0008Uu-00; Mon, 22 Feb 1999 02:24:30 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: (from root@localhost) by troy.blacksheep.org (8.6.12/8.6.12) id CAA04240 for rsgb_lf_group-outgoing; Mon, 22 Feb 1999 02:20:37 GMT Received: from post.thorcom.com (root@post.unica.co.uk [194.75.183.70]) by troy.blacksheep.org (8.6.12/8.6.12) with ESMTP id BAA03545 for ; Mon, 22 Feb 1999 01:51:35 GMT From: G0MRF@aol.com X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from imo20.mx.aol.com ([198.81.17.10]) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10Ehtz-0003vN-00 for rsgb_lf_group@blacksheep.org; Sun, 21 Feb 1999 23:03:08 +0000 Received: from G0MRF@aol.com by imo20.mx.aol.com (IMOv18.1) id QXOZa19752 for ; Sun, 21 Feb 1999 17:58:50 -0500 (EST) Message-ID: <2dfb519b.36d08faa@aol.com> Date: Sun, 21 Feb 1999 17:58:50 EST To: rsgb_lf_group@blacksheep.org MIME-Version: 1.0 Subject: LF: 20/21 Feb.

I managed to work Graham G3XTZ cross band to 80m but no sign of Peter G3LDO. Tried to call Mike, G3XDV via the landline, but no reply. The Rugby transmitter around 73.3 was on which means no chance of any QSOs with our midlands stations...Now I can appreciate the problems faced by DJ8WL and DF2PY with broadcast intermods. Incidentally, I wonder if any of the noise cancelling techniques being developed here could be used to combat the broadcast QRM on the other side of the North Sea Sunday. Nice to see so many L.F.ers at the RSGB VHF rally at Sandown Park. G3XTZ, G3GRO, G3KAU, G4JNT and G3XDV, G3YGF G4FKK - at a distance. Also, had a brief conversation with Peter Blair G3LTF who has appeared on the bands in recent weeks. Peter is well known for his 70 and 23cm moonbounce station but had aquired a large transformer for a new 136kHz amplifier. So look out for a bigger signal from Peter in the near future. PSK31 is working well on receive here, with good signals on 14.070 and 3580.15 The VXO crystal should be here at the end of the week so I'll be ready for a sked with Andy and an RX test with Rik on 137.6 (ish) a few days after. 73 David G0MRF From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 12577 invoked from network); 22 Feb 1999 09:03:44 -0000 Received: from magnet.plus.net.uk (HELO magnet.force9.net) (195.166.128.26) by medusa.plus.net.uk with SMTP; 22 Feb 1999 09:03:44 -0000 Received: (qmail 9871 invoked from network); 22 Feb 1999 09:04:35 -0000 Received: from post.thorcom.com (194.75.130.70) by magnet.plus.net.uk with SMTP; 22 Feb 1999 09:04:35 -0000 Received: from troy.blacksheep.org ([194.75.183.50] ident=root) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10Er8r-00026U-00; Mon, 22 Feb 1999 08:55:05 +0000 Received: (from root@localhost) by troy.blacksheep.org (8.6.12/8.6.12) id IAA10573 for rsgb_lf_group-outgoing; Mon, 22 Feb 1999 08:51:29 GMT Received: from post.thorcom.com (root@post.unica.co.uk [194.75.183.70]) by troy.blacksheep.org (8.6.12/8.6.12) with ESMTP id IAA09343 for ; Mon, 22 Feb 1999 08:04:02 GMT Received: from mb04.swip.net ([193.12.122.208]) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10EqJt-0002Ty-00 for rsgb_lf_group@blacksheep.org; Mon, 22 Feb 1999 08:02:26 +0000 Received: from win95.swipnet.se (dialup154-3-12.swipnet.se [130.244.154.140]) by mb04.swip.net (8.8.8/8.8.8) with ESMTP id IAA21388 for ; Mon, 22 Feb 1999 08:58:40 +0100 (MET) X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Message-ID: <199902220758.IAA21388@mb04.swip.net> From: "Johan Bodin" To: rsgb_lf_group@blacksheep.org Subject: LF: AD9832 0-6 MHz DDS VFO Date: Mon, 22 Feb 1999 08:58:48 +0100 X-MSMail-Priority: Normal X-Priority: 3 X-Mailer: Microsoft Internet Mail 4.70.1155 MIME-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 8bit Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org Hi All, I have put a description of my AD9832 DDS VFO on my web site.

Although it had a +/- 5Hz shortterm and a +/- 50Hz longterm drif it was perfect suitable for normal CW. When starting with slow CW this drift was not tolerable and I decided to built a PLL VFO. I checked out for some special PLL IC's but either they were hard to find or far to expensive, so I just took a handfull of ordinary CMOS IC's (CD4000 series) a constructed a simple PLL VFO on 8.6MHz in 64Hz steps. This signal was divided by 64 to get 136kHz in 1Hz steps. Total cost was about 1000BFR (25 Euro), half of it spent on thumbwheel switches. I ended up with 9 CMOS IC's (OK, you can do it with a single specialized IC but these CMOS are available in any electronics shop and alltogether cheaper than a PLL IC). Everything fits on a 6 by 9 cm piece of 'testboard'. I there is interest I will scan in the schematics and make it available. But do not expect something special it is just a 'textbook' PLL system. 73, Rik ON7YD Rik Strobbe ON7YD rik.strobbe@fys.kuleuven.ac.be Villadreef 14 B-3128 Baal BELGIUM (JO20IX) From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 25324 invoked from network); 22 Feb 1999 09:51:19 -0000 Received: from magnet.plus.net.uk (HELO magnet.force9.net) (195.166.128.26) by medusa.plus.net.uk with SMTP; 22 Feb 1999 09:51:19 -0000 Received: (qmail 19173 invoked from network); 22 Feb 1999 09:52:12 -0000 Received: from post.thorcom.com (194.75.130.70) by magnet.plus.net.uk with SMTP; 22 Feb 1999 09:52:12 -0000 Received: from troy.blacksheep.org ([194.75.183.50] ident=root) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10Es2t-0007Tq-00; Mon, 22 Feb 1999 09:52:59 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: (from root@localhost) by troy.blacksheep.org (8.6.12/8.6.12) id JAA11422 for rsgb_lf_group-outgoing; Mon, 22 Feb 1999 09:49:25 GMT Received: from post.thorcom.com (root@post.unica.co.uk [194.75.183.70]) by troy.blacksheep.org (8.6.12/8.6.12) with ESMTP id JAA11360 for ; Mon, 22 Feb 1999 09:48:50 GMT X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from irwell.zetnet.co.uk ([194.247.47.48] ident=root) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10Eqwg-0008Rj-00 for rsgb_lf_group@blacksheep.org; Mon, 22 Feb 1999 08:42:31 +0000 Received: from central.zetnet.co.uk (central.zetnet.co.uk [194.247.47.20]) by irwell.zetnet.co.uk (8.8.7/8.8.5) with SMTP id IAA24035 for ; Mon, 22 Feb 1999 08:38:46 GMT X-ZSender: g3ldo@zetnet.co.uk Message-ID: <1999022208343368199@zetnet.co.uk> Date: Mon, 22 Feb 1999 08:34:33 GMT To: rsgb_lf_group@blacksheep.org From: "Peter Dodd" X-Mailer: ZIMACS Version 1.20c 10000836 Subject: LF: LF Report 19 - 21 Feb Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org Content-type: text/plain; charset=windows-1252; format=flowed MIME-Version: 1.0 Content-transfer-encoding: 8bit Receiver setup here working much better.

But . . . Spent some time on Friday evening trying to persuade my VFO to cover 73kHz. Having improved its stability on 136kHz by reducing the L and increasing the C, I now find that adding extra C will no longer bring the VFO down to 73 - it just generates noise. No time to do further work this weekend but looks like I need some add-in L rather than C. So, sorry to David, G0MRF, I did try. Saturday 21st Out most of the day helping my son buy his first car. But heard G3UNT (559), G3KEV (599), PA2NJN (a very good 599 but apparently not listening on 136), and GW4ALG (579). Saw on Spectrogram ON7YD (O), IK1ODO (M) and DJ8WL (M). The last two were much weaker than usual with deep QSB on Saturday evening. Worked a new one for me: G6RO, 251km away, at 549/549. My 30th station worked on 136. Sunday Early morning, I heard QSO between G3LDO (599) and PA0SE (559). RSGB VHF Convention in the morning (if you get a chance to see the lecture by Paul Shuch, N6TX, of the SETI League, do so - it is very entertaining), and mother in law in afternoon (not quite so entertaining). When I got home the wind was so strong I lowered the antenna. By the way, having worked GM3YXM/P for the second time early in the week, I heard the start of a QSO between him and Dave, G3YMC. I do hope it was successful as dave is battling against huge odds to get a signal out at all.

We'd like to get a permission to use it during night broadcasting break (approx. 2100z-2300z). In concerning this project I'm interested in any information/programs/etc. If we'll get that permission, I'd like to appoint some skeds...

I'm looking for info on the Redifon G142 MF beacon transmitter which would appear to have some potential for modification to 136 kHz. The TX is all-valved, runs a 3 by 5B/255M PA, plate & screen modulated by a pair of 5B/254Ms and runs MCW or CW. It would appear to be on approx 360 kHz at present, crystal-controlled. I'd like a circuit diagram if possible or at least some idea of it's lower design frequency, the present owner has been told this is around 200kHz. There 2 complete rigs in racks plus another for spares with some component spares as well. Although the seller wants a fairly high QRK for the lot I think this would make an interesting project and am keen to get on the band by this route, if feasible. Finally, one TX is marked "BN", which I take to be it's former callsign, any idea where this was/is?

Each rod has it´s own coil. How should I arrange this array for highest performance? One above the other? Next to each other? On a straight line? Filling a volume? Some years ago I built a "monster" ferrite rod by glueing 5x18cm rods together. It was much better than bundling them. Of course it was too fragile to handle and had only one coil. I don´t know how to simulate a ferrite rod with NEC.

All the info I had been given about NT suggested that progs such as this that operate directly on the PC hardware would not work at all !! For anyone who wants to press an ancient 8086 macine into service - and I know of at least two using an Amstrad 640 etc - the CWSLOW code is compiled to the simplest (8 bit ??) form suitable for these machines. Performance on '286 and higher processors is not compromised - or certainly not in a way that can be seen.

Zim ............ VK3GJZ No, Zim, I don't mind at all! Thats what I try since several days! I will try again: The synthesizer I am using is either available as a kit (see below) or as a build and assembled unit. It makes use of an integrated DDS circuit named AD9850. There are a couple of information sources available for the AD9850. The Analog Devices AD9850 is a CMOS, 125 MHz complete direct digital synthesiser on a single chip. It uses a single 5 V or 3.3 V supply, and with a 125 MHz clock, can generate a low-distortion sine wave or a square wave, from under 1 Hz up to about 60 MHz, with a tuning resolution of 0.0291 Hz. Full data on the device is available from ADI's web site: http://www.analog.com Off course, this device was never created for low-frequency, however, I got hold of a kit that includes a controller and a display, it has one Hertz resolution and ten memory channels and so it is ideal to drive a longwave-PA. It even has a build in correction factor for frequency stability, so once you found out how many ppm you are away from the qrg where the device should be, you can program that permanently into the memory. This allows a freqency stability and repeatability of around 1 Hz From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 23323 invoked from network); 22 Feb 1999 20:18:46 -0000 Received: from magnet.plus.net.uk (HELO magnet.force9.net) (195.166.128.26) by medusa.plus.net.uk with SMTP; 22 Feb 1999 20:18:46 -0000 Received: (qmail 14825 invoked from network); 22 Feb 1999 20:19:41 -0000 Received: from post.thorcom.com (194.75.130.70) by magnet.plus.net.uk with SMTP; 22 Feb 1999 20:19:41 -0000 Content-Transfer-Encoding: 8bit Received: from troy.blacksheep.org ([194.75.183.50] ident=root) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10F1q7-00001K-00; Mon, 22 Feb 1999 20:20:27 +0000 Received: (from root@localhost) by troy.blacksheep.org (8.6.12/8.6.12) id UAA00883 for rsgb_lf_group-outgoing; Mon, 22 Feb 1999 20:16:44 GMT X-Priority: 3 X-MSMail-Priority: Normal Received: from post.thorcom.com (root@post.unica.co.uk [194.75.183.70]) by troy.blacksheep.org (8.6.12/8.6.12) with ESMTP id UAA00737 for ; Mon, 22 Feb 1999 20:02:55 GMT Received: from premium.inrete.it ([194.116.9.4] helo=mailer.inrete.it ident=root) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10F1c6-00073V-00 for rsgb_lf_group@blacksheep.org; Mon, 22 Feb 1999 20:05:59 +0000 Received: from pc-lab (pcttym01.inrete.it [194.116.9.248]) by mailer.inrete.it (8.8.8/8.8.8) with SMTP id VAA06288 for ; Mon, 22 Feb 1999 21:02:01 +0100 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Message-ID: <3.0.3.32.19990222210211.00df500c@mailer.inrete.it> X-Sender: spin@mailer.inrete.it X-Mailer: QUALCOMM Windows Eudora Light Version 3.0.3 (32) Date: Mon, 22 Feb 1999 21:02:11 +0100 To: rsgb_lf_group@blacksheep.org From: "M.

Thanks G0ONA for the info. Does anyone have a source for a quantity of electrolytic capacitors for a 28V supply? 10,000 and up. (30,000 is ideal) @ 30 - 40V.

But with a little bit more power from a new TX. A G3YXM design with the following variations: Vackar VFO on 6.8 MHz and 4*IRFP250 supplied with 35V/20A. So far I've made very good experience with the Vackar (I also used it in my former TX): If temperature compensated it has a good stability, acceptable for SlowCW. Anyway, next project is a DDS. The IRFP250 is very robust (and it handles much more current than the IRFP450) and so far they survived every mismatch. Only protection circuit is an overcurrent protection at 25A, realized with a sensing transistor over a shunt, instead of the hall element. It triggers a Flip-Flop and stops the driver until reset. Unfortunately I am probably now also in the crocodile class: In the past few weeks I've heard often stations, probably calling me, but I couldn't copy them. Especially in QRN caused by "electric" snowfall. Please give me long calls (your call only) so that I get the chance to adjust the receiver and Audio-DSP. Last Sunday I could also receive PA2NJN - he was very strong - about the same as DF2PY. But both are probably also in the crocodile league, hi. Paul, HB9DFQ is now also QRV in Slow CW and I'm trying to get Bert, HB9DCE on this mode. Bert has a very good receiving situation and hears probly better than me. They have both approx. 100W RF and good antennas. Paul is located near Zurich and Bert near Winterthur, 150km NE from my QTH. Sorry for all those stations I missed in the past weeks - we will try again. 73 de Toni From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 7910 invoked from network); 24 Feb 1999 01:22:02 -0000 Received: from magnet.plus.net.uk (HELO magnet.force9.net) (195.166.128.26) by medusa.plus.net.uk with SMTP; 24 Feb 1999 01:22:02 -0000 Received: (qmail 6985 invoked from network); 24 Feb 1999 01:23:05 -0000 Received: from post.thorcom.com (194.75.130.70) by magnet.plus.net.uk with SMTP; 24 Feb 1999 01:23:05 -0000 Received: from troy.blacksheep.org ([194.75.183.50] ident=root) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10FT33-0007j9-00; Wed, 24 Feb 1999 01:23:37 +0000 Received: (from root@localhost) by troy.blacksheep.org (8.6.12/8.6.12) id BAA04505 for rsgb_lf_group-outgoing; Wed, 24 Feb 1999 01:17:57 GMT Received: from post.thorcom.com (root@post.unica.co.uk [194.75.183.70]) by troy.blacksheep.org (8.6.12/8.6.12) with ESMTP id BAA04262 for ; Wed, 24 Feb 1999 01:06:55 GMT Received: from cask.force9.net ([195.166.128.29]) by post.thorcom.com with smtp (Exim 2.04 #3) id 10FSqU-0006Xx-00 for rsgb_lf_group@blacksheep.org; Wed, 24 Feb 1999 01:10:38 +0000 Received: (qmail 26860 invoked from network); 24 Feb 1999 00:25:32 -0000 Received: from relay2.force9.net (195.166.128.25) by cask.force9.net with SMTP; 24 Feb 1999 00:25:32 -0000 Received: (qmail 16122 invoked from network); 23 Feb 1999 22:52:07 -0000 Received: from 07.usr01.wor.dialup.force9.net (HELO main) (195.166.131.7) by relay2.force9.net with SMTP; 23 Feb 1999 22:52:07 -0000 Message-ID: <000c01be5f7d$5467ebc0$0600a8c0@main> From: "Pick" To: "LF Group" Subject: LF: PSK31 Date: Tue, 23 Feb 1999 22:39:05 -0000 MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 4.72.3110.1 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org Dear All, Some of you may have heard me making funny noises on 136.

I'm ready to go anytime with this mode, only about 30 - 40 Watts though. Haven't yet built an 'MRF PA after blowing one of the Maplin modules during the Transatlantic tests earlier. Is that 6dB down on mean power ? As PSK31 has a peak to mean ratio of exactly 3dB I suspect the extra power reduction is to get the transmitter into a suitable linear region. If I hear you I'll reply directly. Had a PSK31 QSO with G3PLX a year ago, 390 km with near 100% copy each way - In the region of 100 Watts each end.

The legal power level is 100W in Russia. Today was a conversation with owner of this BC radiostation... Probably, we'll got a permission! Anyway, I'll start to prepare rig and software... I've got Kenwood TS-570D, Texas Instruments Pentium-133 notebook with 80MB RAM and integrated Sound Blaster. I should build 136kHz transverter or cristall controlled transmitter (if sensitivity of TRCVR is enough for 136). The main problem is PA...

The PA is a hybrid of David's design and my topband FET linear with a pair of IXFH75N10 at 24V. It produces 250W key-down (PEP) and obviously shows less average when sending PSK31 due to the holes in it! Do you intend to use BPSK or QPSK? Any other parameters I should set? I have copied several stations on 80 so the RX works OK. I will put out some calls down the bottom of the band, about 136.2, at around 8pm for the rest of the week. I will listen co-channel.

BPSK is the norm, as it is effectively 3dB up in S/N over QPSK. If the link shows burst errors we transfer to the QPSK mode which is targetted against that sort of interference. There are no other parameters to set, just remember that the Tx tone setting can actually cover the whole of this LF band over its 200 - 2999 Hz range so be carefull if you change it!

The German RegTP (licencing authority) will probably limit the power on LF for German amateurs to 20 watts TX output power in the NEW regulations (presently we are having preliminary regulations allowing the same output only. However, DA0LF was allowed to run 100 watts out...). To avoid getting a flood of replies I am sending this mail as direct question to some amateurs in neighbouring countries asking them for direct reply to my email address. Unfortunately I do not have any addresses in Scandinavia (sorry Johan !) to ask for the same info (Finland, Sweden, Norway etc.) ... Please reply also, as well as others in the East/Southeast of EU : *************************************************************************** ************************** "What are the current regulations on LF regarding output power or transmit power or ERP (for amateurs) written down in your country ? How is it defined (ERP or TX-power output)?" If someone has infos about Luxembourg, Greece, Czech Republic, Lithuania please feel free to reply as well. Any info about other EU countries not mentioned here is also appreciated... *************************************************************************** ************************** Please get back to me with the answer asap.

Since the first release of QRS version 1.08 (november 1998) slow-CW on 136kHz has evoluated from a marginal activity to a popular and widely accepted mode. This created the need to revise QRS, on the one hand to add some features requested by users and on the other hand to make slow CW more efficient and try to reduce the time needed for a QSO. My thanks go to G3YXM, G0AKN and DK8KW for the suggestions to improve QRS and/or for testing it. Overview of the changes from QRS version 1.08 to 1.16 : * Test mode added (suggestion of G0AKN) : Ability to push and release PTT and key for test and tune purposes. * QSO mode added : Since QRS often is used in combination with the Spectogram software, the QSO mode allows optimal use of the screen in combination with Spectogram. It also allows a text of max. 70 characters to be edited and transmitted in a single window. * QSK facilities added : QSK allows you to listen during the 'key up' periods your transmission. Several timing parameters can be set to optimize the QSK for your transmitter. The PTT handling is calculated ahead, so QSK will cause no delay to the CW keying. * Selectable dash to dot ratio : The dash to dot ratio can be set as 3/1 or 2/1. The 2/1 ratio is sufficient to distinguish between dots and dashes using 'videography' and results in an average 20% time saving compared to the 3/1 ratio. * Alarm function (suggestion of DK8KW) : An alarm function is available that will alert you a selectable time (up to 999 seconds) before the transmission will end. QRS is freeware and can be downloaded from : - LWCA web-page : http://members.aol.com/us66soft/qrs.htm - G3YXM's Longwave web-page : http://www.picks.force9.co.uk/136.htm The 1.08 version at this locations should be replaced by the 1.16 version the next couple of days.

Viewing the band using Spectogram shows that within the bandwidth of the narrowest CW filter there may be 18 or 20 Loran sidebands. Each individual sideband is not that strong but is about the same as an O report slow CW signal. Some time ago someone suggested (either G4JNT or G3PLX) that there should no problem in working between these Loran sidebands and although I did not believe it at the time I now know that it is easy - I have been doing it for the last couple of weeks. The following is a description of how the band appears here when clear of evening QRN A frequency quoted as .703 means 137.703kHz. About 8 Loran lines close together .772 - .800 Clear band .769 - .771 Clear band .761 - .763 2 strong Loran lines and noise .755 - .758 Big carrier at .745 with upper sideband noise to .754. (about S6 - 7 in fast CW terms) Lots of weaker Loran sidebands .709 - .742 Clear band .695-.703 Clear band .681 - 690 Clear band .667 - .675 Frequency bands not quoted have Loran sidebands. The problem with the Loran is that many of the sidebands are pulsed so that they look like slow CW signals although I have got to know them now. I worked Peter, DJ8WL OO this evening (1645UT). On peaks his signal was strong enough to be audible using a narrow filter, other times he was down in the noise. Rain static closed in at the end of the QSO. I copied Dave's PSK31 tests which made some pretty pictures on Gram. I measured the centre frequency as .653 with sidebands extending to .671 and .637. Additional single frequency sidebands occured at .702 and .608.

I am not sure why I have such a reliable failure rate with digital circuits - I strongly suspect incompetence. It is not the case that my amplifiers oscillate and my oscillators don't. I seem to be able to make ugly construction RF and AF circuits that work first time so I was looking a solution that did not involve digital circuits. >From crystals box I found two crystals on 10489.37 and 10355.0 kHz respectively. I built two FET Colpits oscillators, firstly with a variable capacitor across the lower frequency oscillator crystal but then found that it worked best (even output across the frequency range) with the variable capacitor in series higher oscillator crystal. While trying to decided on a suitable mixer/filter I saw this e-mail from Peter DF3LP who described a very similar exciter. Peter kindly sent me a copy of his circuit (which uses 5MHz crystals) , which gave me enough ideas to complete the exciter. Apparently the first circuit of this type (that I am aware of) was built by DJ1ZB. The main attraction of this circuit is that if both oscillators are built in the same enclosure with identical components the output frequency is held constant because any drift in one oscillator is compensated for by an equivalent drift in the other. My circuit is made from junk box components and the measured drift was 137.6530kHz to start and 137.6524kHz after 3 hours. In my last e-mail I described a SCW QSO with DJ8WL (using the above exciter I might add) whos name I gave as Geri!

There are many similarities to all our daily receiving experiments on longwave, so with your permission I would like to post this poem her, although it is in German language. Unfortunately, I am unable to translate, however, I know that also some of our non-Germans fellows understand and speak perfectly German (73s to ON7YD): 73 Geri, DK8KW (W1KW) "Fernempfang" Es blitzt der Blick wie ein Diktator Die Hand umkrampft den Kondensator Die Röhren glüh'n, der Kopp desgleichen Nischt is mal wieder zu erreichen Die ganze Tour total vermasselt Es prasselt! Hängt die Antenne denn noch richtig? Die Frage scheint mir äußerst wichtig! Man findet gerade dort sehr oft, ei, ei! Ne Isolierungsschweinerei. Es starrt der Blick zu Dach, verdattert, Es knattert! Heut' macht das Suchen arg Beschwerde Versuchen wir 'ne andre "Erde" Vielleicht liegt an der "Lampe drei", Die unerhörte Schweinerei. Doch wie du hast auch umgemodelt, Es brodelt! Und Vetter Max, Kusine Trude, Sie sitzen grinsend in der Bude. Max stößt die Trude an: Quatsch, komm'! Hurrah! Da pfeift was! Das ist Rom!! Jetzt ruhig, Kinder! Nischt gequasselt! Es prasselt! Dann brodelt's wieder mal ein Endchen, verzweifelt ringst Du beide Händchen, Und könntest du den Trick vollbringen, Würdst du die Füße auch noch ringen. Ein einz'ger Trost nur mach' dich froh', s'geht allen ebenso!!!
