Dear LF Group,
 
I was away from home this morning, so was unable to listen to the earlier broadcasts from SAQ, but I did get back in time to hear the 1230utc broadcast, plus a further un-scheduled broadcast at 1300. As usual, the signal was 599, allthough with heavy background QRN. I also listened to the broadcast with my electro-mechanical RX, which still has not shaken itself to bits yet :-)
 
Cheers, Jim Moritz

Mike,

Dave (G0MRF) has a 250W linear amp design, but I just noticed that his
homepage ( http://www.g0mrf.freeserve.co.uk/lf.htm ) is "dead".
Does anyone know if his homepage moved to a new URL ?

73, Rik ON7YD
Hello Rik / group.
 
During my time at 3B9C the freeserve company was taken over by Wanado. They wiped the account and the site.  I have managed to re-aquire the account but the new company software is having many problems with uploading data.
 
To solve this I have just purchased  g0mrf.com and will shortly be loading the site to this new URL.  If I can resolve the freeserve problem I will run that as a mirror in the short term, but at present www.g0mrf.freeserve.co.uk is QRT

Dear Scott,

 

Very interesting to see the pictures of CKN. I’m sure the two big masts must be the LF antennas – but some of the smaller masts are carrying fixed and rotatable (the ones with 3 horizontal booms at the top) HF log-periodic arrays. For descriptions of something similar, see the data sheets at

 

http://www.tcibr.com/NewFiles/hfbroadants.html

http://www.antennaproducts.com/

 

I think the rotatable arrays are these:

Never seen those “Hula Hoops” before though…

 

I have been looking at the 76.2kHz and 133.1kHz frequencies a bit – unfortunately, 133.1 has quite a lot of QRM from sidebands of the “Datatrack” beacons centered on slightly higher frequency, so a fairly strong signal would be needed to be detectable. 76.2kHz seems to be in the clear though, but nothing seen so far. BTW, does anybody have any info about the Datatrack transmitters? There seem to be a number working on a common frequency – I can’t get a null with a loop antenna.

 

Cheers, Jim Moritz

As you may know, my Web site http://www.weaksignals.com is physically hosted by qsl.net, which more often than not is abysmally slow. So I found a new host here in Italy, which looks much faster, at least to me. But I am fearing this my impression is distorted by the fact that between me and that host there are only a few hops. Could you please check whether from the rest of Europe and better yet from the US the speed of this host is significantly better than that of qsl.net ? Just point your browser to http://weaksignals.i2phd.com and compare the speed to that of http://www.weaksignals.com Depending on your reports I will or will not make the switchover, thanks. 73 Alberto I2PHD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 15066 invoked from network); 5 Jul 2004 21:13:23 -0000 Received: from unknown (HELO ptb-mxscan01.plus.net) (212.159.14.235) by ptb-mailstore03.plus.net with SMTP; 5 Jul 2004 21:13:23 -0000 Received: (qmail 36476 invoked from network); 5 Jul 2004 21:13:22 -0000 X-Filtered-by: Plusnet (hmail v1.01) X-Spam-detection-level: 11 Received: from ptb-mxcore01.plus.net (212.159.14.215) by ptb-mxscan01.plus.net with SMTP; 5 Jul 2004 21:13:17 -0000 Received: from post.thorcom.com ([193.82.116.20]) by ptb-mxcore01.plus.net with esmtp (Exim 4.30; FreeBSD) id 1Bham5-0008Li-HI for dave@picks.force9.co.uk; Mon, 05 Jul 2004 21:13:17 +0000 X-Fake-Domain: majordom Received: from majordom by post.thorcom.com with local (Exim 4.14) id 1Bhalh-0001eG-Ga for rs_out_1@blacksheep.org; Mon, 05 Jul 2004 22:12:53 +0100 Received: from [213.232.95.59] (helo=relay.salmark.net) by post.thorcom.com with esmtp (Exim 4.14) id 1Bhalh-0001e7-31 for rsgb_lf_group@blacksheep.org; Mon, 05 Jul 2004 22:12:53 +0100 Received: from one.surfree.co.uk ([195.80.0.234]) by relay.salmark.net with esmtp (Exim 4.24) id 1BhhLo-0005gX-L5 for rsgb_lf_group@blacksheep.org; Tue, 06 Jul 2004 05:14:36 +0100 X-Fake-Domain: RSGB613192 Received: from RSGB613192 ([212.248.140.42]) by one.surfree.co.uk (8.9.3/8.9.3) with SMTP id XAA25193 for ; Mon, 5 Jul 2004 23:10:52 +0100 X-Bad-Message-ID: no DNS (RSGB613192) Message-ID: <000d01c462d4$edc33a80$045bfea9@RSGB613192> From: "Andy Talbot" To: rsgb_lf_group@blacksheep.org References: <40E9C2A2.4020804@usa.net> Date: Mon, 5 Jul 2004 22:13:30 +0100 MIME-Version: 1.0 X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 6.00.2800.1106 X-MIMEOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 X-Spam-Score: 0.1 (/) X-Spam-Report: autolearn=no,RCVD_IN_SORBS=0.1 Subject: LF: Re: Web site Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Spam-Checker-Version: SpamAssassin 2.63 (2004-01-11) on post.thorcom.com X-Spam-Status: No, hits=0.0 required=5.0 tests=none autolearn=no version=2.63 X-SA-Exim-Scanned: Yes Sender: owner-rsgb_lf_group@blacksheep.org Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group X-SA-Exim-Rcpt-To: rs_out_1@blacksheep.org X-SA-Exim-Scanned: No; SAEximRunCond expanded to false X-PN-SPAMFiltered: yes X-Spam-Rating: 2 The new one (...i2phd.com) is quicker.

From here in Reno, Nevada (near the US west coast), one can download the larger files at > 250 kilobytes / sec. This compares with about 4.4 kilobytes / sec. from qsl.net . I was confused at first, because the new site sometimes seemed slow. It turned out that some areas, e.g. DSPBOX, point to qsl.net, but still show i2phd.com in the address bar, because of the frameset. Of course, any links from there will take you to the qsl.net site. 73, Stewart KK7KA ----- Original Message ----- From: "Alberto di Bene" To: "LF Mailing List" ; Sent: Monday, July 05, 2004 2:05 PM Subject: LF: Web site > Could you please all of you do me a favour ? > As you may know, my Web site http://www.weaksignals.com > is physically hosted by qsl.net, which more often than not is abysmally > slow. > > So I found a new host here in Italy, which looks much faster, at least > to me. > But I am fearing this my impression is distorted by the fact that between > me and that host there are only a few hops. > Could you please check whether from the rest of Europe and better yet > from the US the speed of this host is significantly better than that of > qsl.net ? > > Just point your browser to http://weaksignals.i2phd.com > and compare the speed to that of http://www.weaksignals.com > Depending on your reports I will or will not make the switchover, thanks. > > 73 Alberto I2PHD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 5898 invoked from network); 6 Jul 2004 07:09:05 -0000 Received: from unknown (HELO ptb-spamcore01.plus.net) (192.168.71.1) by ptb-mailstore01.plus.net with SMTP; 6 Jul 2004 07:09:05 -0000 Received: from mailnull by ptb-spamcore01.plus.net with spamcore-l-b (Exim 4.32; FreeBSD) id 1Bhk4d-0002Wi-E1 for dave@picks.force9.co.uk; Tue, 06 Jul 2004 08:09:03 +0100 Received: from [192.168.67.1] (helo=ptb-mxcore01.plus.net) by ptb-spamcore01.plus.net with esmtp (Exim 4.32; FreeBSD) id 1Bhk4d-0002Wd-Bu for dave@picks.force9.co.uk; Tue, 06 Jul 2004 08:09:03 +0100 Received: from post.thorcom.com ([193.82.116.20]) by ptb-mxcore01.plus.net with esmtp (Exim 4.30; FreeBSD) id 1Bhk4d-000Kah-MC for dave@picks.force9.co.uk; Tue, 06 Jul 2004 07:09:03 +0000 Received: from majordom by post.thorcom.com with local (Exim 4.14) id 1Bhk4F-0000Af-33 for rs_out_1@blacksheep.org; Tue, 06 Jul 2004 08:08:39 +0100 Received: from [213.232.95.59] (helo=relay.salmark.net) by post.thorcom.com with esmtp (Exim 4.14) id 1Bhk4E-0000AW-Jj for rsgb_lf_group@blacksheep.org; Tue, 06 Jul 2004 08:08:38 +0100 Received: from mail.uk.thalesgroup.com ([194.128.85.6] helo=crawsmail1.uk.thalesgroup.com) by relay.salmark.net with esmtp (Exim 4.24) id 1BhqeL-0006d4-Ph for rsgb_lf_group@blacksheep.org; Tue, 06 Jul 2004 15:10:21 +0100 Received: from mail.uk.thalesgroup.com (lisc0021.int.rdel.co.uk) by crawsmail1.uk.thalesgroup.com (Content Technologies SMTPRS 4.3.12) with ESMTP id for ; Tue, 6 Jul 2004 08:08:29 +0100 Received: from mail.tms-ltd.com ([193.150.182.140]) by mail.uk.thalesgroup.com (8.12.8/8.12.8) with ESMTP id i6678TA9009688 for ; Tue, 6 Jul 2004 08:08:29 +0100 Received: by mail.tms-ltd.com with Internet Mail Service (5.5.2657.72) id <3J5PSYG5>; Tue, 6 Jul 2004 08:08:47 +0100 Message-ID: <41DD7618430DD411870400D0B746EDED08FD42BB@mail.tms-ltd.com> From: Reeves Paul To: "'rsgb_lf_group@blacksheep.org'" Date: Tue, 6 Jul 2004 08:08:46 +0100 MIME-Version: 1.0 X-Mailer: Internet Mail Service (5.5.2657.72) X-Spam-Score: 0.0 (/) X-Spam-Report: autolearn=no, Subject: LF: RE: Web site Content-Type: text/plain; charset=iso-8859-1; format=flowed X-Spam-Checker-Version: SpamAssassin 2.63 (2004-01-11) on post.thorcom.com X-Spam-Status: No, hits=0.0 required=5.0 tests=none autolearn=no version=2.63 X-SA-Exim-Scanned: Yes Sender: owner-rsgb_lf_group@blacksheep.org Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group X-SA-Exim-Rcpt-To: rs_out_1@blacksheep.org X-SA-Exim-Scanned: No; SAEximRunCond expanded to false X-Spam-Filtered: by PlusNet SpamCORE (v3.00) Content-transfer-encoding: 8bit Hi Alberto, The new site is MUCH quicker for downloads.

These days all kind of spam and "harassment" filters seem to check your mail before it reaches its destination. Discussing some technical topics with a US colleague one of my mail didn't get through, at the end a phrase "you have to dig deeper into the literature" caused the problem. It turned out that a mail filter (at the mail server !) had problems with "dig deeper". In all my innocence I thought that only twisted minded people would make a sexual link to that, but these days even mail servers seem to have a dirty mind ... 73, Rik ON7YD PS : I wonder if this mail makes it through the reflector At 09:45 6/07/2004 +0100, you wrote: >I tried many times to send a recent message through the >reflector withiut success.

Sorry Mike, though a recent "joiner" I can't remember what was received. It just "worked" from day one so I guess it must be user friendly for a lot. Perhaps a very new internet user might need help.

Could you please check whether from the rest of Europe and better yet from the US the speed of this host is significantly better than that of qsl.net ?

It looks like there is a general consensus that the new site is faster, so I will do the switch probably during this week, after having finished setting it up. As Stewart pointed out, there are still links to qsl.net that must be changed, and that content moved to the new server. But I have to make a public confession here, hoping that the owners of the new server are not reading this list, which seems unlikely. The new server is a server that offers free space, at the price of placing some advertising on your pages. I found a way to defeat this.... You should have seen the new pages free of any banners or advertising. What I ask you is to alert me if suddenly this is no more true. That would mean that they discovered my trick... in such a case I would have to put into operation "Plan B", but let's hope it won't be necessary :-) TNX es 73 Alberto I2PHD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 56603 invoked from network); 6 Jul 2004 17:19:39 -0000 Received: from unknown (HELO ptb-spamcore02.plus.net) (192.168.71.3) by ptb-mailstore01.plus.net with SMTP; 6 Jul 2004 17:19:39 -0000 Received: from mailnull by ptb-spamcore02.plus.net with spamcore-l-b (Exim 4.32; FreeBSD) id 1BhtbT-0000AJ-8I for dave@picks.force9.co.uk; Tue, 06 Jul 2004 18:19:35 +0100 Received: from [192.168.67.2] (helo=ptb-mxcore02.plus.net) by ptb-spamcore02.plus.net with esmtp (Exim 4.32; FreeBSD) id 1BhtbT-00009r-5N for dave@picks.force9.co.uk; Tue, 06 Jul 2004 18:19:35 +0100 Received: from post.thorcom.com ([193.82.116.20]) by ptb-mxcore02.plus.net with esmtp (Exim) id 1BhtbU-000FFz-MZ for dave@picks.force9.co.uk; Tue, 06 Jul 2004 17:19:36 +0000 Received: from majordom by post.thorcom.com with local (Exim 4.14) id 1Bhtaq-00042X-4E for rs_out_1@blacksheep.org; Tue, 06 Jul 2004 18:18:56 +0100 Received: from [213.232.95.59] (helo=relay.salmark.net) by post.thorcom.com with esmtp (Exim 4.14) id 1Bhtap-00042K-Hg for rsgb_lf_group@blacksheep.org; Tue, 06 Jul 2004 18:18:55 +0100 Received: from mta05-svc.ntlworld.com ([62.253.162.45]) by relay.salmark.net with esmtp (Exim 4.24) id 1Bi0Ax-0007pa-78 for rsgb_lf_group@blacksheep.org; Wed, 07 Jul 2004 01:20:39 +0100 Received: from captbrian ([80.1.84.165]) by mta05-svc.ntlworld.com (InterMail vM.4.01.03.37 201-229-121-137-20020806) with SMTP id <20040706171222.HVLT2927.mta05-svc.ntlworld.com@captbrian> for ; Tue, 6 Jul 2004 18:12:22 +0100 Message-ID: <007701c4637c$f1b238a0$a5540150@captbrian> From: "captbrian" To: rsgb_lf_group@blacksheep.org References: <40E52108.5060805@g3ysx.org.uk><003c01c4607a$e9a381a0$b42565d5@oemcomputer><000d01c46206$b3791800$90540150@captbrian><005b01c462bc$2e489960$a82465d5@oemcomputer><001201c462cf$99ecc5c0$55540150@captbrian> Date: Tue, 6 Jul 2004 18:16:08 +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 V5.00.2615.200 X-Spam-Score: 0.1 (/) X-Spam-Report: autolearn=no,RCVD_IN_SORBS=0.1 Subject: Re: LF: Re: Re: Re: UNESCO declares SAQ as a World Heritage Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Spam-Checker-Version: SpamAssassin 2.63 (2004-01-11) on post.thorcom.com X-Spam-Status: No, hits=0.0 required=5.0 tests=none autolearn=no version=2.63 X-SA-Exim-Scanned: Yes Sender: owner-rsgb_lf_group@blacksheep.org Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group X-SA-Exim-Rcpt-To: rs_out_1@blacksheep.org X-SA-Exim-Scanned: No; SAEximRunCond expanded to false X-Spam-Filtered: by PlusNet SpamCORE (v3.00) What issue/page ?

Depending how majordomo is set up, yes. One of its options is a feature to allow certain administrative tasks to be done by sending messages to the list by e-mail. Majordomo watches for certain keywords to determine if it's an administrative command. Such a message does not go to the list members, but is processed by majordomo itself--IF the message also contains a password, and if the syntax is correct. However, if a list member unintentionally uses one of the keywords, the message simply dies in transit. In a majordomo installation, this feature is on by default. I was surprised when we uncovered the fact by accident on the lwca.org reflector, since it's a potential security weakness. I suspect the manager of this reflector became aware of it through majordomo error messages when you attempted to post previously. If so, he has now turned it off, because Mike WE0H managed to post a quote containing a couple of the keywords just a few hours after your "Forbidden word?" query. 73 John From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 85020 invoked from network); 6 Jul 2004 21:52:07 -0000 Received: from unknown (HELO ptb-spamcore02.plus.net) (192.168.71.3) by ptb-mailstore02.plus.net with SMTP; 6 Jul 2004 21:52:07 -0000 Received: from mailnull by ptb-spamcore02.plus.net with spamcore-l-b (Exim 4.32; FreeBSD) id 1BhxrB-000Jzu-La for dave@picks.force9.co.uk; Tue, 06 Jul 2004 22:52:05 +0100 Received: from [192.168.67.3] (helo=ptb-mxcore03.plus.net) by ptb-spamcore02.plus.net with esmtp (Exim 4.32; FreeBSD) id 1BhxrB-000Jzg-HC for dave@picks.force9.co.uk; Tue, 06 Jul 2004 22:52:05 +0100 Received: from post.thorcom.com ([193.82.116.20]) by ptb-mxcore03.plus.net with esmtp (Exim) id 1BhxrB-000Crd-4w for dave@picks.force9.co.uk; Tue, 06 Jul 2004 22:52:05 +0100 Received: from majordom by post.thorcom.com with local (Exim 4.14) id 1BhxqT-00035h-MN for rs_out_1@blacksheep.org; Tue, 06 Jul 2004 22:51:21 +0100 Received: from [213.232.95.59] (helo=relay.salmark.net) by post.thorcom.com with esmtp (Exim 4.14) id 1BhxqT-00035Y-8D for rsgb_lf_group@blacksheep.org; Tue, 06 Jul 2004 22:51:21 +0100 Received: from mail.algerfn.com ([63.171.43.8] helo=ms.genesis-technology.com) by relay.salmark.net with esmtp (Exim 4.24) id 1Bi4Qa-0008RJ-LJ for rsgb_lf_group@blacksheep.org; Wed, 07 Jul 2004 05:53:04 +0100 Received: from we0h (rev-65.165.20.192.genesiswireless.us [65.165.20.192]) by ms.genesis-technology.com (8.12.9/8.12.9) with SMTP id i66LopeN023181 for ; Tue, 6 Jul 2004 16:50:51 -0500 From: "WE0H" To: rsgb_lf_group@blacksheep.org Date: Tue, 6 Jul 2004 16:51:49 -0500 Message-ID: MIME-Version: 1.0 X-Priority: 3 (Normal) X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook IMO, Build 9.0.6604 (9.0.2911.0) Importance: Normal In-Reply-To: <128.45a0ba73.2e1c7531@aol.com> X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1409 X-Scanned-By: MIMEDefang 2.36 X-Spam-Score: 0.0 (/) X-Spam-Report: autolearn=no, Subject: RE: LF: Forbidden word?

Does anyone have to instructions for using the "Tin Plating Crystals" as sold by RS in the past.  
Their stock number is 567-812.  The only writing on the jar keeps saying how dangerous it is, how it will kill everyone in sight and probably should be considered as a Weapon of Mass Destruction, but nothing about how to use properly
 
I've inherited a jar of the stuff, but without any instructions for use.  It was thrown away on health and safety grounds as being too dangerous to have in the lab, so I offered to get rid of that hazardous waste. 
 
A few years ago managed to pick up a PCB bubble etch machine the same way, along with a couple of UV exposure boxes and enough FeCl3 to last a lifetime. 
 
What would we do without all this wonderful H & S legislation!
 
On teh same subject, stock up on all the tin / lead solder you can get hold of.  There will be a lot on the surplus market over the next few years as the Pb free legislation bites.  There ought to be a lot of surplus components with the wrong sort of tinned leads appearing too.

It says..... Deposition rates of tin to tin 1.5 microns in the first half hour, and up to 3 to 4 microns in 2 hours, can be achieved at an optimum room temperature. 5 lites of solution may be made by disolving the pack (450gms) in 5 lites of solution (note not 5 litres of water) at 50 deg C. This is enough for 2.7 sq m of board ( I suppose they mean copper) I think that is probably the information you want. I think we used to call this "electroless tin-plate" I remember using something like it for putting temporary electrodes on silicon slices. We used a photo-electrolytic polishing system, the electrolyte was hydrofluoric acid and glycerine....now there is something really nasty. For etching dont use a bubble etcher, they are terribly messy and distribute a fine, almost aerosol, spray of ferric chloride everywhere, which you dont notice for about 2 days after which clothing and furniture starts to fall apart. If they are the vertical type they also tend to etch unevenly...top to bottom so you have the rotate the board halfway though...messy. I prefer a ice cream carton (they even have a little bulge in the middle of the base to stop the board "ringing" down) with just enough fresh etch to cover the board warmed to about 40 deg C by immersing in a bath of hot water, and steady gentle rocking agitation..... about 5 to 7 mins a board. Tiring but worth the effort. Once used etch kept for the more crude projects, where you can just leave it and not worry about undercutting fine lines. Disposal (important these days) is easy, neutralise the used etch with garden lime (very cheap). It is actually safe to bury then I believe....probably good for reducing earth resistance and better for the soil that common salt.

I just completed the variometer and a simple K0LR type TX on steriods (5-15W) that will be used to tune the antenna system and begin low power beacon tests. A CW QSO with VE7SL will be attempted in the coming days and we have both discussed running both stations in beacon mode over the weekend a few Hz apart and at low power... Within a week or so the power level will be raised to ~100W and when I feel that I'm not going to burn down the neighbourhood brief periods of 300W+ trials will begin. If these trials are succesful the TX will be sent to Steve for further field trials and work will begin on the 1KW transmitter. Our activity will be centered around 137.574KHz. Major updates on the LowFER and LF refectors. Presently LowFER 'TIL' is on to assist Steve is selecting the best time and antenna configuration to conduct our planned QSO with. The LowFER will be decommisioned this evening for the time being...

I'll make up a solution in that proportion and give it a try. Being able to tin plate home made PCBs may solve the not too major problem of them becoming oxidised and not so nice to look at a few days after construction - though after all the joints have been made fortunately. I have been using the bubble etch tank for some time, in the garage then utility room, and have seen no adverse effects from a fine FeCl3 mist - it is the vertical sort. I only tend to do little boards, (SMT components for everything these days, they're much easier to use). I have noticed a certain difference in etch rate between top and bottom, but its so quick when hot and the FeCl3 is fresh that its hardly important. The copper on normal PCB material is only 3.5microns, so that is quite an extra deposition. Andy 'JNT Hi Andy an old paper RS cat gives some information, though it would seem there is no data sheet.

Kepro, a US company that is in the small batch - at home pc board business, used to sell (and may still) an immersion tin plate solution. While the plating soldered well and looked shiny initially it did deteriorate over time. After about a year it would oxidize to a very dull gray color and soldering became difficult requiring seemingly too much heat and flux during rework. It might have been possible to prevent the oxidation by spraying the board with a conformal coating once it was de fluxed - but I never tried that. What I've been doing lately is to mount the board to a nearly vertical surface and coat the board with solder using a 40-watt iron top to bottom. While I can't get the solder to flow quite as smoothly as the professional circuit board houses, it does look pretty smooth and bright once it is defluxed. It seems to hold up better than tin plate...a light spray of conformal coating would probably still be a good idea. my 2 cents...for what it's worth.

I used to use some stuff called Amonium Bi-flouride in 1960. I used it to etch crystals for SSB filters etc. You could buy it from any chemist (although they didn't normally stock it). You made a solution of it in a plastic container and just dropped the crystal in and washed and checked the crystal frequency at frequent periods to make sure you didn't overshoot. The plastic container was kept on the shack windowsill and the fumes from it caused the lower pane of the window to frost over! Nevertheless, I found the most dangerious item around a shack is a high voltage power supply (and the high voltage at the top of an LF loading coil), and it is impossible to apply H & S legislation to that.

Sorry for that.

To All from PA0SE,

Gert-Jan van den Berg, PA2P,  advises me he has available two PVC pipes of about 133 mm diameter and about 1.5 m long.  These are to be scrapped.

But if you would like to receive them please contact PA2P directly at g-berg@wanadoo.nl.

The 2200m station was successfully comissioned yesterday with a QSO with Steve, VE7SL.  Despite the finals in my amp being taken out buy a passing lightning storm!  The one day a year we get one and it was comissioning day!
 
We must have angered the LF gods...
 
The station will be running in beacon mode for the next little while testing my push-pull TX design at modest power levels.
 
Please seemy status page for upto date details as it will reflect my activity...
 
Steve is putting together the details of the QSO for those that are interested and this will be posted soon.
 
73,
Scott

The QSO was completed yesterday on 137.754 kHz. ( July 10th) between myself, VE7SL (Mayne Island, BC - CN88) and Scott Tiley, VE7TIL (Vancouver, BC - CN89), a distance of approximately 50km. At the time of our initial two-way QSO, Scott's transmitter consisted of a homebrew DDS exciter using a Darlington-pair final running about 1W output. My transmitter was also homebrewed, using a crystal controlled exciter into a single FET amplifier at 100W out. Both of us used similar antenna systems for transmitting, a loaded three-wire flattop 'T' . On receive, both stations used small backyard loop antennas. Being the only 2200m activity west of Ontario, it is hoped that our efforts will stimulate more interest in LF on the west coast and western provinces. As well, we are both working towards improvements in antenna systems and increased power levels for the upcoming winter season. 73...Steve McDonald / VE7SL 'THE VE7SL RADIO NOTEBOOK' : http://www.imagenisp.ca/jsm [L.F.

Hi Mike
 
AOL 7030
 
But as this was at the recommendation of Alan G3NYK he would be the best one to comment and his opinions would do for me as well.
 
All in all I think it's a hell of a Rx at any freq in its range!
 
Also FRG7700 but with mod to bypass attenuator and via a separate LPF into mixer stage - works but not measured for performance! The noise blanker is effective with some of my local impulse noise.

I have the optional 250Hz filter, which is very good for LF, if a bit narrow for HF. With the filter, it needs 1uV for 10dB SNR on 136k. This gives adequate RX sensitivity with my TX wire antenna resonated with a suitable coil - for smaller antennas, a preamp is required. The sensitivity deteriorates as the frequency decreases. The noise blanker doesn't seem to do very much at LF; the preamp causes a loss of sensitivity. The AGC has the effect of turning the LF band noise into a uniform mush, which does not help readability much, and you can't switch it off, but backing off the RF gain improves things a lot. I think it is quite usable for LF, allthough obviously not ideal.

Both ours are fitted with Rockell-Collins 300Hz filters. I generally dont find the noise blanker which is available on the "Plus" version useful on 136kHz. It could be I have the "Wrong kind of noise" (with apologies to BR, Railtrack, and whoever runs trains now) I have also used a Lowe HF150 to good effect, this tunes down to 30kHz. The problems are no RF gain control, no AGC OFF switch, no ability to electronically lock the tuning knob and only a 2.1kHz filter with no option to fit others, however the IDM performance is much better than rigs costing a lot more. I used it successfully in my early "SWL" (or should it be "LWL" !!) days with a good audio filter....probably before Jim became active!! He would cause havoc with the AGC here. I believe from Finbar that the Lowe HF225, which can be fitted with a narrow filter, is very good (and Finbar is a REAL operator, unlike me!) The Trio/Kenwood R1000 only really tunes down to 200kHz and rolls off rapidly below that. It is possible to feed a signal into a test-point after the RF octave filters, and disable the BC IF attenuator, but the performance is not good and it has no provision for IF CW filter, or AGC OFF. The noise blanker never seemed any good for anything except car ignition to me. Tuning resolution is 1kHz. I have used it with a converter but the FT101ZD with narrow filter was much better in that mode. I believe there are several Racal RA1792s around in use (Brian has a couple, and I think Andy uses one) I would like to be able to report on an AR88LF (I dont have one now) but I would have to go into weight-training first!!

I am compiling a list of receivers and transceivers suitable

does anyone use a radio made in, say, the last five years

Loran? Is a narrow filter fitted as standard?

Your help would be appreciated.

Have never noticed intermods etc even putting a big antenna on it. Have used it quite a lot away from base with only a small 2m whip which works well. My ICOM IC-756PRO (Mk. 1) is just about sensitive enough on its own provided I use a big antenna, but then it's very prone to intermod problems from LW B/C. You can hear background chatter from the B/C's all the time. With a 25 dB preamp that has 500 Hz selectivity ahead of it it's fine, but the outboard selectivity is essential to get rid of the intermod. My Kenwood TS-870 is just not sensitive enough on its own even with a big antenna (can hardly hear DCF!) so it needs the outboard preamp/selectivity like the 756. Guess the last two were never designed for LF. The HF-225 is my preference considered as a bare-bones LF receiver. I also have an AR88LF which is fine on sensitivity and selectivity but drifts far too much to be usable for narrow-band stuff. I've also tried an old R1155N which tunes down to 75 kHz on 136 but its selectivity and frequency stability are awful. That's an old WW2 RAF receiver for those who don't know it.

The sensitivity is good however; the input impedance of this type of RX is designed to be quite high on the LF bands, so a wire antenna can be connected directly without additional tuning components. If one were to fit a modern IF filter, the performance would be quite good. I also have had good results using a Telefunken ELK639 - this is an early solid-state marine receiver, with two separate gang-tuned front ends which tune 9.8kHz - 30MHz. This has good mechanical filters, and also works well with a directly connected antenna. Still hasn't got a product detector though... Mostly I use the Racal RA1792, which gives good performance at 136k, and is usable to below 15kHz. The only problem is that the IF filters are not as good as current receivers, so there is a noticeable, although not serious, leakage of adjacent strong signals. The front panel controls are a bit idiosyncratic too. The older RA1772 is similar. These receivers have the advantage of very good frequency stability due to the internal crystal oven, and the facility to connect external frequency standards, e.g. GPS-derrived. Also, the RF and IF signal paths are easy to get at, so I would recommend these for the more experimentally minded.

The TX is a homebrew push-pull arrangement similar to the G0MRF design. The latest version of the SM6LKM exciter was used. The mode was QRSS30. I live in the city of Vancouver proper with a small urban lot with lots of power wires all around so things are less then optimal. The ground system here consists of a direct connect via a piece of #4AWG to the plumbling system entering my home. The beacon will continue to run to qualify the TX design for the coming days. The power will be increased to ~300W either tonight or tomorrow.

Noise blanker, 2 settings [Kill or Ruin] works too good so i never use it watching LF. In PSK31 or NAVTEX the NB seems to enhance the signal, too bad it does not allways work in CW. AGC settings are adjustable from 0.04 to 5.1 seconds and can be set to off also. 3 preset filters for cw 2.7K, 1K and 500 Hz and 10 Hz steps adjustable fm 10 Hz to 9.99Khz. Values differ when another mode is used but stay adjustable. PBS is +2.30 Khz and -2.30 Khz, a double one would be more usefull as on the TS-940. AGC discharge time, Bandwidth and PBS settings are displayed on a separate LDC, nice at night :-) 1 Hz tuning steps. Notch and a tracking notch wich tracks a carrier up and down for 10 Khz even if the VFO is used. 2 audio output sockets with same signals. Came with TCXO and is steady in 120 Sec Qrss right from power up until the paint comes off. Fine rig for LF, CW, Digimodes etc etc but it sounds terrible in SSB nomatter what speaker is used with it, Takes time to get used to and too bad the DSP can't be switched off. 73 Ko, NL9222 From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 94969 invoked from network); 13 Jul 2004 21:23:48 -0000 Received: from unknown (HELO ptb-spamcore01.plus.net) (192.168.71.1) by ptb-mailstore01.plus.net with SMTP; 13 Jul 2004 21:23:48 -0000 Received: from [192.168.67.2] (helo=ptb-mxcore02.plus.net) by ptb-spamcore01.plus.net with esmtp (Exim 4.32; FreeBSD) id 1BkUlg-000LaB-Q2 for dave@picks.force9.co.uk; Tue, 13 Jul 2004 22:24:52 +0100 Received: from post.thorcom.com ([193.82.116.20]) by ptb-mxcore02.plus.net with esmtp (Exim) id 1BkUkc-0001Nb-05 for dave@picks.force9.co.uk; Tue, 13 Jul 2004 21:23:46 +0000 Received: from majordom by post.thorcom.com with local (Exim 4.14) id 1BkUkD-0002Ru-1o for rs_out_1@blacksheep.org; Tue, 13 Jul 2004 22:23:21 +0100 Received: from [193.82.116.30] (helo=relay.thorcom.net) by post.thorcom.com with esmtp (Exim 4.14) id 1BkUkC-0002Rl-Lq for rsgb_lf_group@blacksheep.org; Tue, 13 Jul 2004 22:23:20 +0100 Received: from rwcrmhc12.comcast.net ([216.148.227.85]) by relay.thorcom.net with esmtp (Exim 4.34) id 1BkUk9-0000o1-4u for rsgb_lf_group@blacksheep.org; Tue, 13 Jul 2004 22:23:20 +0100 Received: from Charlie_Drake (pcp02166593pcs.lebnon01.pa.comcast.net[68.83.127.219]) by comcast.net (rwcrmhc12) with SMTP id <20040713212308014004b1cve>; Tue, 13 Jul 2004 21:23:09 +0000 From: Steve Dove To: rsgb_lf_group@blacksheep.org Date: Tue, 13 Jul 2004 21:23:06 -0000 X-Priority: 3 (Normal) Organization: d s p In-Reply-To: <40F2CF45.30049.6CA6CC@localhost> Message-Id: <2UQHFXT742W54RLMH21WSQLA65ZRLYV.40f452ba@Charlie_Drake> MIME-Version: 1.0 X-Mailer: Opera 6.04 build 1135 X-Spam-Score: 0.1 (/) X-Spam-Report: autolearn=no,RCVD_IN_SORBS=0.1 Subject: Re: LF: Receivers Content-Type: text/plain; charset=US-ASCII; format=flowed X-Spam-Checker-Version: SpamAssassin 2.63 (2004-01-11) on post.thorcom.com X-Spam-Status: No, hits=0.0 required=5.0 tests=none autolearn=no version=2.63 X-SA-Exim-Scanned: Yes Sender: owner-rsgb_lf_group@blacksheep.org Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group X-SA-Exim-Rcpt-To: rs_out_1@blacksheep.org X-SA-Exim-Scanned: No; SAEximRunCond expanded to false X-Spam-Filtered: by PlusNet SpamCORE (v3.00) Content-transfer-encoding: 8bit Hi Mike, Icom R-75: 'Consumer Reports' and 'Which?' magazine four-star best buy. As has been mentioned, the R-75 works very well out of the box at LF, and has become a fave amongst 'Lowfers' over here. I have a couple and they're mainstays for the 'Grabulators'. Further to other remarks, under software control the AGC can be made 'Very Fast', intended for use during scanning as a poor man's spectrum analyser. But it is quite useful as an alternative to turning the AGC off and letting the receiver clip/saturate on static crashes - 'Argo' seems to make nicer plots under 'Very Fast'. The receiver uses a single lowpass filter for 1.6MHz and below - no transition at 500kHz-ish. There is a fixed attenuator in this path of nominally 3dB, presumably just to secure a sane source impedance for the filter. However, its removal makes considerably more difference than that with highly reactive and hi-Z LF-ey antennas - the input impedance of the first mixer is probably quite a bit higher than 50R. No obvious nasty side-effects from the attenuator's removal and is so considered a plus. Inrad's 125Hz filter makes for a well worthwhile 'microscope'; for most circumstances if the radio is in a house the TCXO is not worth it; the DSP option is useless for LF; the noise blanker is amazing - allowing plots to be made under lighting-dimmer noise if need be. Kenwood TS-440: Has a discrete front-end filter-set for 500kHz and below, with no fixed attenuator and is very sensitive even down to 100kHz. Optional filter (500Hz or 270Hz Kenwood, 400Hz or 250Hz Inrad) a must. Ho-hum noise blanker. Recommended - circuitry and performance almost identical to the highly- regarded TS-850. Kenwood TS-140: A real surprise for an 'entry-level' radio. Very lively down to 200kHz, sensitivity dropping off towards 100kHz but still adequately sensitive at 136kHz - in fact this one here has been sitting collecting dust plotting DCF-39 for however long now. Same front-end filter as 1.6MHz and below, but below 500kHz the fixed attenuator is switched out - thank you Kenwood! There is tons of room to kluge in a <500kHz filter in that position. IC-781: Very good at LF. Just a bit too much radio for the job! IC-751a: Very sensitive at LF, but d r i f t s way too much for QRSS, and so can't be recommended except for a band-cruiser. Hope this is helpful. Cheers, Steve 07/12/04 16:49:57, "Mike Dennison" wrote: >I am compiling a list of receivers and transceivers suitable >for 136kHz.

Good initiative and very instructive about all equipments at the present time used to be "hip" ;-) At this time the receive station except for some selective voltmeters like SPM3 and SPM60 ( Wandel & Goltermann), i use a FT 847 centered on 5 MHz and a converter. The mixer is a SRA-8 ( MCL) to be in front of a BPF 7 poles cheb. design, 0.2 dB ripple (i am located very near a big marine transmitter). The RX BW is 250 Hz ( optianal xtal filter). The receive antenna is a loop built with a old 5/8 coax cable (6 turns and 2meter diameter) to keep a high Q ( ~500). All this equipments are not fully finish at this time ( more on the bench like on the air!), i count on the next leaves...

A large sun-spot rotated onto the visible disc, and the X-ray background showed an appreciable increase. Then followed a series of M-Class flares, the biggest being an M6.0 early on the 13th, followed by a number of slightly smaller events. This morning (15th) at 0100 there was a massive X1.8 flare. Propagation conditions will be affected by the Coronal Mass Ejections (CME) emitted with these flares, the first sizable one ,from the M6 is expected later today. The CME from the X1.8 will probably not arrive until about Saturday 17th. Long distance night-time DX conditions will probably deteriorate from Saturday night, and the effects could linger for about 3 weeks. Watch the Dst index figures on my web page to judge the state of the recovery. As a bonus daytime conditions should be enhanced for a few days, probably starting Sunday 18th.

Callsigns: ZC4CW or ZC4LOW (for experiments). I need advice on using a grounded tower as a vertical radiator on 136KHz. It's approximately 60m high and I can't climb it. This rules out some of the existing methods which rely on accessing the top of the tower. Shunt feeding has proven effective on 160m, however can this be done on 136KHz. I would be open to other alternatives.

Shunt feeding will be very difficult as you will face a impedance of only a few micro-Ohms. So you can expect huge currents (= need of thick wire) and high losses in the matching circuitry. 60m might seem a lot, but it's only 2.7% of the wavelength. So scaled to 160m it's no more than a 4.5m tower or scaled to 20m just a 60cm tower. 73, Rik ON7YD At 15:02 16/07/2004 +0300, you wrote: >Hello, > >New to 136KHz. > >Callsigns: ZC4CW or ZC4LOW (for experiments). > >I need advice on using a grounded tower as a vertical radiator on 136KHz. >It's approximately 60m high and I can't climb it.

The 1041 flare (Class X1.1) shows a 10dB enhancement on Brian's 24 hour plot, followed by a 15 dB absorption dip as the flux dies away. This is probably because the declining flux produces a lower level of ionisation below the "reflection height" resulting in increased absorption. The peak only lasted a few minutes.

The further up the tower the shunt feed is connected, the better it will be, but even if the connection is right at the top (i.e. a folded monopole configuration), it will still be very inefficient. At 136k, the shunt feed would nearly behave as a short circuit - a folded monopole 60m high could be modeled as a vertical monopole with perhaps of the order of 1 kohm capacitive reactance, shunted by an inductive reactance of some 10s of ohms, due to the shorted stub formed by the shunt feed. This would make the circulating current in the matching network of the order of several tens of times larger than the "useful" antenna current, increasing the losses in the matching network by something of the order of 1000 compared to an insulated mast with matching components of the same Q. In your case, with the feed point far below the top, things will be even worse. I suspect that a wire insulated from the mast would be a better bet, even if it can only be attached part of the way up - many people are getting reasonable results with wire antennas 10 - 20m high, although 60m would be nicer, of course! If the problem is simply one of accessibility, one idea might be to treat the mast as a big tree, and get a line over or through it using bow and arrows, catapults etc ... then again, if it is someone's telecoms mast covered in microwave antennas, this might not go down too well!

Next to my patch there's a 150ft (50m) deep well that has dried up and the owner now intends to fill it in. He doesn't mind me dropping a few copper wires down it before he does so. Question: is this a better use of 400 ft of copper wire for earthing purposes than simply spreading it out along the ground as radials in the traditional way? Re the tower - use a decent crossbow and you'll get over the top no trouble. I have a 200lb draw one that I once used to put a wire over a 50m mast and it could have gone much higher.

Actually it may not be such a daft train of thought. Disconnect tower grounding strap(s) - there should be at least one (inteded to "arrest" lightning ?) and check to see if tower really is "earthed" via foundations. The surprise might be that future lightning protection might be via your shack but you might get an antenna as a side effect !

With winter rains however you may get a much wetter bottom (I could have phrased that better ) at the deep end of the wire - especially if it had a wide surface area at the bottom - old copper hot water tanks are good. Why more than one wire? a length of small-bore heating pipe would be better - you could pump water down it in summer. or keep it connected to bottom of a rain-barrel so whatever you collect in the rain barrel finds its way to the deep down copper tank electrode. Where do you get "a decent crossbow" ? I vaguely though they were illegal? My arm aches from throwing plastic milk bottles full of water over trees to the peril of my neighbours.

Any thoughts on if a matching transformer should 'click' when the key is released... Obviously it is likely an inductive reaction to the rapid change in current supplied... When I connect the 48V supply to the system the finals don't last long... OK at 12 and 24V so I feel it is a inductive kickback that's blasting the 200V rated FETs...  The system works great into a 6 ohm load driver pushpull without the match xfmr...  It must be the inductive kickback...
 
Perhaps the inductance of the windings it too great?
 
Damn physics... To quote a power engineer friend of mine "it's a damn shame that FETs behave the way they do, otherwise they would be the perfect device..."

Add in a little "off-tune" and it can be higher. I have 500 volt devices pencilled in for the 50 volt supply. I do find a "click" from my feed choke when the key goes down.... there is a physical movement of the wires round the core. (that is 36 V and about 5 amps) even into a resistive dummy load. I suppose the only way to soft keying would be to "PWM" the drive during keying. I believe that if you use the keying / drive circuit used by Dave G0MRF and also G3YXM with the TI fet driver chip (TC4426).....this does soften the edges a bit in this way.

The tower *will* be earthed enough via its foundation(s) to cause significant loss to the radiated signal in any case, given the high RF voltages present on a resonated short antenna, but it will no longer be earthed well enough to provide a decent path for lightning currents. Apart from blasting one's rig to little charred pieces, and very possibly toasting the operator to a cinder, a lightning strike of sufficient peak current can fracture the foundation and allow the tower to fall.

As Rik said, it may be useful in conjunction with other earthing--if you want additional grounding of DC or 50 Hz. However, that long a run of wire, going straight down, has quite a bit of lossy soil between it and the RF from your antenna.

200V FETs probably are being hit by some fairly high voltages. I have seen 200V spikes from a 35V supply line, particually when the load impedance is incorrect.
On one TX here that operates from a 48 - 56V SMPSU, I had to fit 400V FETs. That solved the problem and gave 600W output. Other choice is to to fit 200V 'transorbs' (?) across the devices. If the spikes are narrow this may be OK. If not, it's only one more thing to catch fire (hi)

Hi Mike.
 
I converted my version of the 250W linear to class D by fitting a 4013 chip and the TC4426 FET driver etc from the other class D circuit. I used the IRFP450.
 
With no other changes  it gave 600 W out from a 48V supply and had some spare capacity for those moments when you really want the QSO (about 700W CW on 56V)
I would have thought 60V was the max safe limit. An oscillosope on the drains will be enough to shock you into not going beyond that (it was for me)
 
Also used the same amp for a 500km QSO on 73kHz from Scotland. It clicked and fizzed like crazy on that band, but held up OK

It would require a series capacitor to get resonance, plus a step-down transformer to match the TX load impedance. The trouble is that the impedance transformation produced by the shunt feed will convert the tenths of an ohm radiation resistance into micro-ohms at the feed point, which will just be lost in the loss resistance of the feed components.

Dear Scott, LF Group,
 
It is fairly normal for ferrite-cored transformers to make funny clicks and squeals due to magnetostriction of the ferrite. This is the magnetic version of the piezo-electric effect; as the flux density changes, the dimensions of the ferrite change, leading to vibration of the core. It doesn't seem to do much harm.
 
The voltage experienced by the FETs depends on the circuit configuration - assuming we are talking about an "MRF" type of push-pull circuit, in an ideal circuit with a purely resistive load, the peak drain voltage will be twice the supply voltage. It will be slightly higher if the circuit is a "current fed" configuration with a capacitive-input low pass filter. In practice, the presence of HF ringing potentially leads to much higher voltages; the best way to tell is to connect an oscilloscope to the drain, which may reveal frightening results! As was discussed on the reflector some weeks back, this can be minimised by reducing the output transformer leakage inductance to the minimum, keeping the primary inductance low, and connecting series RC damping from each drain to ground. If you are using a low-pass filter on the output with a shunt input capacitor, you will also need a suitable un-bypassed choke feeding the DC into the centre tap of the transformer primary. However, these measures will reduce but not entirely eliminate the ringing, and the peak drain voltage in my amplifier is about 3 - 3.5 times the supply voltage. So 48V supply should be OK with 200V devices, provided suitable attention is paid to the ringing. Certainly, there are several TXs around operating at similar levels. If there is excessive ringing, the MOSFETS behave as big zener diodes, clipping the waveform and dissipating a lot of heat in the process. The TO220 devices in the pictures on your web site will not be able to dissipate much more power than they are already at 300W output, so this is certainly something to look for.
 
The class E design seems to give cleaner waveforms, but results in higher peak voltage in the first place - the component values are probably more critical too. Also, as Alan points out, you have to think about what can happen when the antenna goes off-tune and gives a highly reactive load. I reckon the push-pull design has the virtue of simlicity for supply voltages less than about 50V. Another possibility suitable for higher supply voltages is the 'Decca' bridge configuration (or the "half-bridge" as used by G4JNT in his off-line design). This circuit topology is inherently self-limiting, a feature that effectively limits the peak MOSFET voltage to a little over the DC supply voltage.
 
Cheers, Jim Moritz

Any thoughts on if a matching transformer should 'click' when the key is released... Obviously it is likely an inductive reaction to the rapid change in current supplied...

I am now formally retired from Academe, but ironically immediately have been asked back to continue some activities. And so it is less easy to get a student here for this project, but I will try. However it may have to be elsewhere, perhaps at some other academic establishment - any offers?! I will look at it anyway, but at the moment it will not be at the top of the priority list. I would like to start collecting evidence since the theory and simulations in this frequency area are not particularly good for loops or for small verticals in a real environment. At this stage theoretical proofs and simulations only have a fifty-fifty chance of answering the question correctly! Even what might be regarded as anecdotal evidence on the topic is very welcome from anyone. The type of environment is an essential part of the equation and so results in different environments are particularly of interest.

Regards to all on the list Mike U - G3LHZ To: 'rsgb_lf_group@blacksheep.org' Subject: RE: LF: Loops v Verticals Importance: High I view of the continuing arguments about this issue, is there anyone who knows, or knows someone, with the mathmatical understanding of antenna theory as well as the common sense, to come up with a point at which loops will perform better than verticals, for given criteria. A useful criterion might be the same amount of copper (include loading coil) in the antenna system, or a given amount of ground area. Every parameter has to be taken into account so its far from trivial, but must be calculatable. It would certainly make a suitable task for a PhD thesis (Mike U.. are you there?) Any deep analysis was way beyond me, but in the early days of 73kHz when we had a proper LF band rather than this high frequency stuff above 100kHz, I did some some simplistic spreadsheets that did suggest that for VERY LARGE loops (many tens or 100s of metres in effective diameter) there was an advantage over electric antennas of similar size, but for anything that would fit in a typical garden E field won every time. If the loop could be made metres in diameter for example, or of Litz conductors to this diameter, then it copuld be made smaller for a given efficiency, but the total of amount copper actually increased. Then there comes a point where the loop is of the same dimensions as the vertical, so what mode is then radiating (Mike U, are you still there ?) etc etc. This was borne out by G2AKV in Canterbury who used a huge loop of bog standard mains cable, quite low down and draped thorough trees. He was the strongest signal on the band for a long time (unreceivable because of his chirp, but that's another story). Just making uninformed or sarky comments isn't going to solve anything.

I intend to do some beaconing tonight.

Start at about 2100 UTC on July 23.

Stop at about 0600 UTC on July 24.

Mode will be  DFCW30 on 135922 Hz (dash frequency; dots about 0.5 Hz lower)

DFCW is a new mode for me.

Power about 178 W  (2.3 A aerial current into 33.8 ohms resistance of the aerial/coil/earth system).

Reports will be welcome.

Thanks for the thoughts James!
 
I seem to have the system under control into a 50ohm dumby load.  The wave form across the drian/grd is a ringing square wave that seems to settle out about twice the supply voltage and peaks at ~140V with a 24V supply.  The problems start when I place a 5 element C in/out LPF in the line(same as G0MRF design...) The square wave is gone and a number of ringing peaks take over. The FETs get warm fast! Any thoughts?
 
I'm using 'Street Ferrite' for the matching xfmr out of an old VGA monitor...

Subject: LF: Re: clicking matching transformer...

Dear Scott, LF Group,
 
It is fairly normal for ferrite-cored transformers to make funny clicks and squeals due to magnetostriction of the ferrite. This is the magnetic version of the piezo-electric effect; as the flux density changes, the dimensions of the ferrite change, leading to vibration of the core. It doesn't seem to do much harm.
 
The voltage experienced by the FETs depends on the circuit configuration - assuming we are talking about an "MRF" type of push-pull circuit, in an ideal circuit with a purely resistive load, the peak drain voltage will be twice the supply voltage. It will be slightly higher if the circuit is a "current fed" configuration with a capacitive-input low pass filter. In practice, the presence of HF ringing potentially leads to much higher voltages; the best way to tell is to connect an oscilloscope to the drain, which may reveal frightening results! As was discussed on the reflector some weeks back, this can be minimised by reducing the output transformer leakage inductance to the minimum, keeping the primary inductance low, and connecting series RC damping from each drain to ground. If you are using a low-pass filter on the output with a shunt input capacitor, you will also need a suitable un-bypassed choke feeding the DC into the centre tap of the transformer primary. However, these measures will reduce but not entirely eliminate the ringing, and the peak drain voltage in my amplifier is about 3 - 3.5 times the supply voltage. So 48V supply should be OK with 200V devices, provided suitable attention is paid to the ringing. Certainly, there are several TXs around operating at similar levels. If there is excessive ringing, the MOSFETS behave as big zener diodes, clipping the waveform and dissipating a lot of heat in the process. The TO220 devices in the pictures on your web site will not be able to dissipate much more power than they are already at 300W output, so this is certainly something to look for.
 
The class E design seems to give cleaner waveforms, but results in higher peak voltage in the first place - the component values are probably more critical too. Also, as Alan points out, you have to think about what can happen when the antenna goes off-tune and gives a highly reactive load. I reckon the push-pull design has the virtue of simlicity for supply voltages less than about 50V. Another possibility suitable for higher supply voltages is the 'Decca' bridge configuration (or the "half-bridge" as used by G4JNT in his off-line design). This circuit topology is inherently self-limiting, a feature that effectively limits the peak MOSFET voltage to a little over the DC supply voltage.
 
Cheers, Jim Moritz

Any thoughts on if a matching transformer should 'click' when the key is released... Obviously it is likely an inductive reaction to the rapid change in current supplied...

Sunday morning before last there was the usual hive of activity on 136, not a signal to be heard, so I put my auto keyer on with the Tx running at the 800 watt level while I went and got on with the gardening. Part way thro a long, long CQ, the far end 200 ft fell off my 1100 ft antenna, thus presenting a considerable mis-match to the transmitter. When I returned to the shack, I observed that the antenna current had dropped from the normal 4 amps to less than an amp. The PA appears to have survived without damage. The point about this is that the only protection my Tx has is an over current limit, which had not tripped. There is no SWR protection. The PA is a 'chinese' copy of the Decca 4 FET bridge circuit, but with a 'YXM/MRF' output circuit with LPF and tapped transformer instead of the Decca series tuned circuit. I would recommend anyone to use this arrangement because it seems to be bomb proof and I have yet to lose a FET. I cannot say the same about the 2 X FET 'YXM/MRF' PA configuration used previously. I still have the pile of dead FETs! 73, Tom G3OLB p.s I still didn't get an answer to my CQ!

Andy G4JNT. AD9852 Direct Digital Synthesiser Module This DDS unit is capable of being clocked at up to 300M Samples./ second, so can be used to generate a signal from DC up to approximately 100MHz with a resolution of micro-Hertz. The module, when completed, contains a clock source, the DDS chip, power supply regulators and a PIC microcontroller to allow a simple interface for programming over a serial link to a PC. Once frequencies are programmed, the settings can be saved in non volatile memory for automatic start up next time power is applied. As well as generation of CW signals, the chip is capable of generating automatic Frequency Shift Keying between two arbitrary frequencies, amplitude control and automatic ramping and chirp generation. All these features can be accessed over the serial link. An external clock input can be used, and the on-chip PLL multiplier allows this to be multiplied between 4 to 20 times, meaning that a 10 MHz reference signal from a high stability oscillator can be used to directly give a clock of 200MHz which in turn will allow any frequency up to approximately 70MHz to be generated. Power output is approximately 4dBm and pads on the PCB allow the components for a 5th order elliptic low-pass filter to be installed. The unit is built on a double sided PCB with plated through holes, board dimensions are 93 x 58mm. A 3.3 Volt voltage regulator needs to be mounted on a separate heatsink, but apart from that components are SMT types fitted on the top side of the PCB. The module will run from a power supply voltage between 6.5 to 15 Volts. Current consumption depends on the clock frequency in use but is typically about 500mA for a 240MHz, reducing to around 200mA for 30MHz clock. G4JNT Part Kit. The part kit contains the PCB, AD9852ASQ chip and a programmed 16F84 PIC for the controller. The rest of the components need to be supplied by the user, and these consist of chip resistors and capacitors, two voltage regulators, crystal oscillator module (or other frequency source) and a small ferrite transformer for matching the output. This last item can be omitted and replaced by two resistors if 6dB lower power output is acceptable. Assembly and use instructions are supplied, but to gain full advantage of the device's capabilities, these need to be read in conjunction with the data sheet for the AD9852 available from www.analog.com. The only other item needed will be a PC running Hypertrm serial driver software, or any other serial terminal capable of plain ASCII text at 19200 baud. Software Support A virtually limitless set of control functions can be programmed into the PIC controller, and at some point a rotary encoder / LCD display system will be written to allow a complete single box DC to VHF synthesiser to be constructed. The PIC is configured for on board programming, or alternatively can be mounted in a socket. Purchasers of the kit will have free software support if the PIC can be self programmed, (this may be possible at some microwave and LF roundtables) alternatively PIC upgrades will be available from myself at prices to be announced.

Dear Scott, LF Group,
 
To save long-winded explanations, I have drawn a circuit diagram of my modified version of the G0MRF PA output circuit, with some details of the output transformer. It is too big to send via the reflector, but if anyone wants it, let me know and I will e-mail it direct.
 
My unit gives 400W out with 37V supply - for 300W out with a 48V supply, I reckon the primary windings of the output transformer should be changed from 4 to 6 turns. The value of the choke in the DC supply is not critical - the iron dust cores can often be found in old PC SMPSUs. The most significant change to the original circuit was to remove the decoupling capacitor from the centre tap of the transformer primary, and increase the inductance of the choke, converting the circuit into a "current feed" class D configuration. This means the DC supply has a high impedance at 137kHz, which prevents high transient currents into the low pass filter capacitors when the MOSFETs switch. The ideal drain voltage waveform would be a half sine wave, allthough in practice there is still considerable ringing at the switching transitions, allthough much reduced. The value of the damping resistors and capacitors is a compromise; reducing R and increasing C reduces the amount of HF ringing, but increases dissipation in the resistors.
 
Cheers, Jim Moritz

I have been using a YXM modified design PA for years and todate no FETs zapped. I use 4 fets and run up to 800W out and have been higher but my PSU is the limiting factor. I use around 18 volts key down, solid PSU transformer. The current is heavy but not a problem, no ringing, buzzing etc.
I also have 2 Decca Jeeps (5501) they also run cool but I prefer to use my home built system. I have used old TV line cores to see what difference it makes and they work just as well as the 3c80 cores.
I prefer normal CW but have used QRS 60 by request for transatlantic,  the FET'S  and the LPF components run cool, barely warm.  I do use a fan on the PA and another on the LPF.
Cannot understand why so many are having problems.
I do make a point of having the antenna properly resonant and matched on the required frequency. My antenna base loading inductor is around 0.3 mH for the Vertical.
There is a trick about how to wind the PA transformer, it seems I am the only one that knows about it, although having tried the  conventional way it worked fine.

For those that do not know. Research around Europe has shown that VERTICALS are the only antennas suitable for Transmitting on LF. Loops are fine for Receiving, little or large but the bigger the better. Who has ever heard of a LF broadcasting station using loops for TX.

Subject: LF: Re: TX output circuit

Dear Scott, LF Group,
 
To save long-winded explanations, I have drawn a circuit diagram of my modified version of the G0MRF PA output circuit, with some details of the output transformer. It is too big to send via the reflector, but if anyone wants it, let me know and I will e-mail it direct.
 
My unit gives 400W out with 37V supply - for 300W out with a 48V supply, I reckon the primary windings of the output transformer should be changed from 4 to 6 turns. The value of the choke in the DC supply is not critical - the iron dust cores can often be found in old PC SMPSUs. The most significant change to the original circuit was to remove the decoupling capacitor from the centre tap of the transformer primary, and increase the inductance of the choke, converting the circuit into a "current feed" class D configuration. This means the DC supply has a high impedance at 137kHz, which prevents high transient currents into the low pass filter capacitors when the MOSFETs switch. The ideal drain voltage waveform would be a half sine wave, allthough in practice there is still considerable ringing at the switching transitions, allthough much reduced. The value of the damping resistors and capacitors is a compromise; reducing R and increasing C reduces the amount of HF ringing, but increases dissipation in the resistors.
 
Cheers, Jim Moritz

Hmmmm
 
broadcasters want omni coverage so a loop
really wouldnt work in this application
 
however for Amateur work they would appear to work
quite well,, The proof is in the pudding where a TX at
1 watt input provides good coverage,,,  if it weren't for TX loops
folk with small lots and shade trees ,,,LF activity would certainly suffer
 
But verticals do work after a fashion

For those that do not know. Research around Europe has shown that VERTICALS are the only antennas suitable for Transmitting on LF. Loops are fine for Receiving, little or large but the bigger the better. Who has ever heard of a LF broadcasting station using loops for TX.

"Dear Scott, LF Group,
 
To save long-winded explanations, I have drawn a circuit diagram of my modified version of the G0MRF PA output circuit, with some details of the output transformer. It is too big to send via the reflector, but if anyone wants it, let me know and I will e-mail it direct."

Subject: LF: Re: TX output circuit

Dear Scott, LF Group,
 
To save long-winded explanations, I have drawn a circuit diagram of my modified version of the G0MRF PA output circuit, with some details of the output transformer. It is too big to send via the reflector, but if anyone wants it, let me know and I will e-mail it direct.
 
My unit gives 400W out with 37V supply - for 300W out with a 48V supply, I reckon the primary windings of the output transformer should be changed from 4 to 6 turns. The value of the choke in the DC supply is not critical - the iron dust cores can often be found in old PC SMPSUs. The most significant change to the original circuit was to remove the decoupling capacitor from the centre tap of the transformer primary, and increase the inductance of the choke, converting the circuit into a "current feed" class D configuration. This means the DC supply has a high impedance at 137kHz, which prevents high transient currents into the low pass filter capacitors when the MOSFETs switch. The ideal drain voltage waveform would be a half sine wave, allthough in practice there is still considerable ringing at the switching transitions, allthough much reduced. The value of the damping resistors and capacitors is a compromise; reducing R and increasing C reduces the amount of HF ringing, but increases dissipation in the resistors.
 
Cheers, Jim Moritz

VE7TIL is presently beaconing in QRSS30 on ~137572.7Hz. The transmitter has been 'precisely' matched :) with the new scopematch (thanks Jim, M0MBU!)
 
This is the prototype TX with IRF640 finals running from a 24V supply with ~ 9A input current... A new matching xfmr was wound for this setup... Looks good so far and has survived 100% duty cycle tests on the bench for 48+ hours...
 
Presently running ~200W input...

A useful criterion might be the same amount of copper (include loading coil) in the antenna system, or a given amount of ground area. Every parameter has to be taken into account so its far from trivial, but must be calculatable. It would certainly make a suitable task for a PhD thesis (Mike U.. are you there?) Any deep analysis was way beyond me, but in the early days of 73kHz when we had a proper LF band rather than this high frequency stuff above 100kHz, I did some some simplistic spreadsheets that did suggest that for VERY LARGE loops (many tens or 100s of metres in effective diameter) there was an advantage over electric antennas of similar size, but for anything that would fit in a typical garden E field won every time. If the loop could be made metres in diameter for example, or of Litz conductors to this diameter, then it copuld be made smaller for a given efficiency, but the total of amount copper actually increased. Then there comes a point where the loop is of the same dimensions as the vertical, so what mode is then radiating (Mike U, are you still there ?) etc etc. This was borne out by G2AKV in Canterbury who used a huge loop of bog standard mains cable, quite low down and draped thorough trees. He was the strongest signal on the band for a long time (unreceivable because of his chirp, but that's another story). Just making uninformed or sarky comments isn't going to solve anything.

So there is no reason to use loop in this case in my opinion. 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 2996 invoked from network); 21 Jul 2004 12:46:21 -0000 Received: from unknown (HELO ptb-spamcore01.plus.net) (192.168.71.1) by ptb-mailstore01.plus.net with SMTP; 21 Jul 2004 12:46:21 -0000 Received: from [192.168.67.3] (helo=ptb-mxcore03.plus.net) by ptb-spamcore01.plus.net with esmtp (Exim 4.32; FreeBSD) id 1BnGUa-0007oH-Cc for dave@picks.force9.co.uk; Wed, 21 Jul 2004 13:46:40 +0100 Received: from post.thorcom.com ([193.82.116.20]) by ptb-mxcore03.plus.net with esmtp (Exim) id 1BnGUF-000EMG-0D for dave@picks.force9.co.uk; Wed, 21 Jul 2004 13:46:19 +0100 Received: from majordom by post.thorcom.com with local (Exim 4.14) id 1BnGTb-0000zZ-9o for rs_out_1@blacksheep.org; Wed, 21 Jul 2004 13:45:39 +0100 Received: from [193.82.116.30] (helo=relay.thorcom.net) by post.thorcom.com with esmtp (Exim 4.14) id 1BnGTa-0000zQ-TL for rsgb_lf_group@blacksheep.org; Wed, 21 Jul 2004 13:45:38 +0100 Received: from cas-mta3-fe.casema.nl ([83.80.1.28] helo=mta.casema.nl) by relay.thorcom.net with esmtp (Exim 4.34) id 1BnGTS-0006Mr-Ov for rsgb_lf_group@blacksheep.org; Wed, 21 Jul 2004 13:45:38 +0100 Received: from pcprive (535582D3.cable.casema.nl [83.85.130.211]) by cas-mta3.mgmt.casema.nl (iPlanet Messaging Server 5.2 HotFix 1.21 (built Sep 8 2003)) with SMTP id <0I1700M6SCROH8@cas-mta3.mgmt.casema.nl> for rsgb_lf_group@blacksheep.org; Wed, 21 Jul 2004 14:45:24 +0200 (CEST) Date: Wed, 21 Jul 2004 14:45:24 +0200 From: haagrimbergen To: rsgb_lf_group@blacksheep.org Message-id: <001601c46f20$9801ade0$d3825553@pcprive> MIME-version: 1.0 X-MIMEOLE: Produced By Microsoft MimeOLE V5.00.2615.200 X-Mailer: Microsoft Outlook Express 5.00.2615.200 X-Priority: 3 X-MSMail-priority: Normal X-Spam-Score: 0.8 (/) X-Spam-Report: autolearn=no,HTML_30_40=0.809,HTML_MESSAGE=0.001 Subject: LF: Another kind of LF-PA?

Dear OM's
 
I was pondering over using the horizontal TV-deflection system as a PA for LF. By stretching the flyback time to 50 percent of the period, using a push-pull stage with two identical circuits and then subtracting both outputs from each other should give a nearly perfect sine-output.
 So I breadboarded a test circuit with two IRF730 FET's and after ample experiments it resulted in over 50 W RF on 136 kHz in a 50 ohm dummyload with 70 V dc input. Efficiency proved to be over 90 percent. Vdrain was abt 260 V peak and Isource of each FET was abt 2.2 A peak, both well within spec.
 Measured with a spectrum-analyser: even harmonics were more than 40 dB and 3rd harmonic was 23 dB below fundamental.
 
 Is this contraption already known yet as an LF-PA ??
 If so, then:
                 1) What class of operation is it ?
                 2) I re-invented the wheel.
 
   Thanks in advance for your comments

I'm not sure where you have gotten the impression that anyone is claiming that a well constructed vertical antenna in a clear area is inferior to a loop for transmitting at LF. The vertical is certainly the best option for people with the resources to do it right. In reading your messages over the years, you have consistently discouraged radio activities in which one could not be the biggest, the best and the first. My only fear is that fellows new to the craft would take this seriously, and feel too limited by equipment, money and real estate to even try participating in LF work.

I think it is probably time to thank everyone who has contributed(?) to this topic and move on to the less emotional pursuit of scientific knowledge with a little less of the "biggest/best/first" argument 'cos I doubt that a Nobel prize lies in that direction!

We US of A operators don't have any LF Amateur Radio bands so we can't drive our loops with the same level of power you run. I don't know why Bill Ashlock hasn't jumped in here, but in my opinion, the only fair way to compare the TX loop to your vertical would be to fly Bill over to your house and have him install one of his designed and tuned TX loops and drive it with the exact power level and mode of operation as you are using on your vertical. Now you would have a damn good comparison test of the Loop verses Mal's vertical.

Everyone doesn't have the knowledge or resources as the other guy has, so I believe all operators should be treated with respect for what they use and operate. At least they are on the band whether someone hears them or not. They enjoy what they do and I hope you enjoy what you do. We US LF operators respect each other whether we hate the other guy or not. We never post bullshit about others ideas. We don't pick fights on the US LF reflector. We don't piss and moan about the other guys equipment, antennas or their pissy ass attitude, let alone what he or she thinks would be a good station. It is all called respect for another human being and the understanding that they too have ideas, just like you do.

I invite you to come to my house and build whatever wire vertical you can on my lot. I have the Ashlock TX loop in the air already. We can operate under my Part-5 license with high power if you like. We'll let the US LF group decide which antenna works best in my backyard. Enjoy your vertical Mal. I hope it continues to work well for many years. I'll enjoy my antennas also. Have a good day.

73's es later dude,
Mike

For those that do not know. Research around Europe has shown that
      
VERTICALS
  
are the only antennas suitable for Transmitting on LF. Loops are fine for
Receiving, little or large but the bigger the better. Who has ever heard
    
of
  
a LF broadcasting station using loops for TX. <

Mal,

Perhaps because no LF broadcasting stations operate from small garden back
yards with trees and no open space.

I certainly have no quarrel with research done in Europe. Please encourage
those doing it to use this forum to discuss it. Thus far, I have only seen
your discouraging comments versus positive results from U.S.
    
experimenters.

Who in the U.S. has worked the distance on a loop that I have covered on
normal CW using a vertical
  
Scarborought to Russia, you must have read about it. If you need more info
    
let me know.

This is exactly the crux of the matter. Mathematically, for a given height of electrically short vertical antenna, a loop having the same diameter (or else the same length and height) will be the inferior performer IF both are in the clear--and, it is directional, which may be disadvantageous. If they are not in the clear, environmental factors degrade the vertical's field strength faster than the loop's. This is a dreadfully old and pointless debate. Mathematically and empirically, the results have long been established. Huge verticals=wonderful at LF if you have the wherewithal. Short verticals=acceptable if you have adequate clear space and ground conductivity. Loops of comparable dimensions to small vertical=compromised performance, but far from useless! If one is not among the chosen few with half-vast tracts of land for an antenna farm, he must sometimes make compromises to accomplish anything at all.

Many thanks to all who have contributed their thoughts to me regarding my battles with my transmitter.
 
Please see my 2200m TX page by following the link to see '2200m TX -part2- innocent pawns'... 
 
 
This photo essay is a summary of the TX work todate...  I hope to have things sorted out by the time Steve, VE7SL returns so we can begin 'production' of a couple of medium power TXs to get some useful signals out.
 
Another interesting aside.  James Dean, VE3IQ, Radio Amateurs of Canada rep to Industry Canada has advised that the 'authorities' in Canada are very interested to see what a 2200m amateur radio station will look like; hence, my documention activities.  We want to convince the navy that we will be good neighbours!
 
As always constructive comments are welcome!

Hi All
At least this topic has injected some interest into the LF scene. LF activity around Europe has virtually died, in fact at present it is a dead duck.
 My comparison between loops and verticals is based on an open clear site and qualifies the merit of the antennas and NOT the environment that that you live in.
I do not know anything about a vertical that leans up against a pine tree or a loop hooked over trees and bushes. I think anyone in that environment would be at a big disadvantage engineering a LF antenna system.
When I visited Long Beach California some years ago and met W6AM and his friends they all had acres of land covered in rhombics and naturally I thought all USA amateurs were in a similar situation, it appears that I am wrong and things are tough on the East Coast USA when it comes to space for LF antennas.
I suppose in some cases some sort of antenna, even a loop is better than nothing.
Did I read somewhere a while back that using a small loop the antenna current would be 76 amps for 1W of RF erp output, If this is the case the atu components and wire would MELT, so it would not be practical. Using a modest vertical around 100 feet to get the same output the antenna current would only be several amps.
I was intrigued reading the opinions of those interested in this discussion, and what a response.

Hmmmm
 
broadcasters want omni coverage so a loop
really wouldnt work in this application
 
Not true. Broadcast stns located in coastal areas do not waste energy beaming out to sea. Likewise the old marine coastal stations working ships at sea tried to direct the RF seawards and not inland.
I never did see any LOOP antennas at these installations.
Loops do have the disadvantage of being bi-directional and not what a radio amateur wants. On LF we want coverage in all directions.

however for Amateur work they would appear to work
quite well,, The proof is in the pudding where a TX at
1 watt input provides good coverage,,,  if it weren't for TX loops
folk with small lots and shade trees ,,,LF activity would certainly suffer
 
But verticals do work after a fashion

Actually, Mal, 76 Amps (if that is the true figure) may be accomodated with good materials and equally good engineering practice. However, the argument then becomes a debate about economics and returns on investment. I think what we should be talking about here is how to encourage more to get involved and to experiment and try ideas. Once upon a time the authorities thought that by confining "amateurs" to "wavelengths below 200 metres" there would be few if any who would be heard outside their own backyards! The history of science and technology is littered with the corpses of debunkers and quack doctors but equally decorated with the laurels of those who had the balls and temerity to "fly outside the envelope". "Is there anyone out there?" only requires that a coherent signal is presented to a random noise Universe. It doesn't even need a callsign identifier.Most of us in the amateur radio world are attempting to either ask that question on a band of interest or maybe just to demonstrate our presence. If folks are led to believe that only the achievement of "biggest/best/loudest/first!" is good enough then what encouragement is left for the guy who wants to try something different? Where is the incentive if his efforts when published are to be ridiculed or condescended on? I have always believed our hobby (and scientific interest) was bigger than this and much bigger than the people who transiently (and we are all transients) participate.
 
And if you think this a boring diatribe, just start me off after a good dinner and a decent claret !

Not a boring diatribe; it is well said.
 
If a person is truly interested he will persevere  [ when I was 16, the thought that little me ,in the attic of my fathers house in  S.Wales, could at the press of a key alter the potential between two ends of a housewife's wet washing line in far away Texas was so absorbing that I have been making things to do just that ever since]
 
"Encouragement" can be vastly overdone. The current policy of a well known UK organisation to positively cajole  people into a hobby that is of only passing interest, by making entry almost a form filling exercise has meant that "most of us"  are not attempting any such thing but using radio  as an oral version of internet chat-rooms . That would be fine if it were not on the amateur bands  but we have reached a situation where in fact only a tiny minority "in the amateur radio world are attempting to ask [any] question or demonstrate [ anything ] ......but that does not apply to anyone on this list, which has cheered me no end since I subscribed.

Yes, well Brian, The "most of us" I should have identified, I agree, are those who have a soldering iron almost as close (closer?) than a microphone or key! However we mustn't be that politically correct for the greater numbers of those who require acres of spectrum in which to play provide the strength in numbers the rest of us need in which to develop the technical criteria of their toys.

That may not always be the case. If experimentation disagrees with theory you need to check that everything is accounted for, before assuming the theory is wrong and reworking it. It is too easy to overlook some seemingly trivial little thing or ignore the seemingly obvious. Like baluns on antenna measurements - just as an example. I've often found that theory based on back of envelope calculations, made from first principles, has this annoying habit of often being surprisingly accurate.

But the point is that the EH-antenna priests have a different point of view. They claim that their toy is a breakthrough in the electromagnetic theories. According to them the classical theory (Maxwell's) cannot explain the PVS (Poynting Vector Synthesis), which, still according to them, is the reason why the EH-antenna works. So they claim for a revision of the classical theory. Now this claim is founded on the experimental evidence that, somehow, the EH-antenna seems to radiate. Hence, from the fact that experiment apparently is not in complete accord with theory, they want to change the theory. What they fail to understand (in good faith or for more venal reasons...) is that the error is in the experiment, as what radiates in their tests is the feeder line, as shown by other tests performed by open-minded persons, not adepts of the EH religion. 73 Alberto I2PHD From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 69312 invoked from network); 23 Jul 2004 14:54:43 -0000 Received: from unknown (HELO ptb-spamcore02.plus.net) (192.168.71.3) by ptb-mailstore02.plus.net with SMTP; 23 Jul 2004 14:54:43 -0000 Received: from mailnull by ptb-spamcore02.plus.net with spamcore-l-b (Exim 4.32; FreeBSD) id 1Bo1SG-000FOy-SC for dave@picks.force9.co.uk; Fri, 23 Jul 2004 15:55:25 +0100 Received: from [192.168.67.3] (helo=ptb-mxcore03.plus.net) by ptb-spamcore02.plus.net with esmtp (Exim 4.32; FreeBSD) id 1Bo1SG-000FOb-P0 for dave@picks.force9.co.uk; Fri, 23 Jul 2004 15:55:24 +0100 Received: from post.thorcom.com ([193.82.116.20]) by ptb-mxcore03.plus.net with esmtp (Exim) id 1Bo1RY-0002B2-FU for dave@picks.force9.co.uk; Fri, 23 Jul 2004 15:54:40 +0100 Received: from majordom by post.thorcom.com with local (Exim 4.14) id 1Bo1R7-0005bF-DD for rs_out_1@blacksheep.org; Fri, 23 Jul 2004 15:54:13 +0100 Received: from [193.82.116.30] (helo=relay.thorcom.net) by post.thorcom.com with esmtp (Exim 4.14) id 1Bo1R7-0005b6-0M for rsgb_lf_group@blacksheep.org; Fri, 23 Jul 2004 15:54:13 +0100 Received: from sj-iport-2-in.cisco.com ([171.71.176.71] helo=sj-iport-2.cisco.com) by relay.thorcom.net with esmtp (Exim 4.34) id 1Bo1R3-0006zp-5J for rsgb_lf_group@blacksheep.org; Fri, 23 Jul 2004 15:54:12 +0100 Received: from sj-core-2.cisco.com (171.71.177.254) by sj-iport-2.cisco.com with ESMTP; 23 Jul 2004 07:56:12 -0700 Received: from cisco.com (mrwint.cisco.com [64.103.71.48]) by sj-core-2.cisco.com (8.12.10/8.12.6) with ESMTP id i6NErxIV025877 for ; Fri, 23 Jul 2004 07:54:00 -0700 (PDT) Received: from g3ysx.org.uk (ams-clip-vpn-dhcp369.cisco.com [10.61.65.113]) by cisco.com (8.8.8-Cisco List Logging/8.8.8) with ESMTP id PAA00220 for ; Fri, 23 Jul 2004 15:53:57 +0100 (BST) Message-ID: <41012684.5030501@g3ysx.org.uk> Date: Fri, 23 Jul 2004 15:53:56 +0100 From: Stewart Bryant User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4) Gecko/20030624 Netscape/7.1 (ax) X-Accept-Language: en-us, en MIME-Version: 1.0 To: rsgb_lf_group@blacksheep.org References: <01C470B0.228BAA70.actalbot@southsurf.com> In-Reply-To: <01C470B0.228BAA70.actalbot@southsurf.com> X-Spam-Score: 0.1 (/) X-Spam-Report: autolearn=no,RATWR10_MESSID=0.111 Subject: Re: LF: Re: Loops v Verticals Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 8bit X-Spam-Checker-Version: SpamAssassin 2.63 (2004-01-11) on post.thorcom.com X-Spam-Status: No, hits=0.0 required=5.0 tests=none autolearn=no version=2.63 X-SA-Exim-Scanned: Yes Sender: owner-rsgb_lf_group@blacksheep.org Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group X-SA-Exim-Rcpt-To: rs_out_1@blacksheep.org X-SA-Exim-Scanned: No; SAEximRunCond expanded to false X-Spam-Filtered: by PlusNet SpamCORE (v3.00) Andy wrote: >Well... >That may not always be the case. > >If experimentation disagrees with theory you need to check that everything is >accounted for, before assuming the theory is wrong and reworking it. > >It is too easy to overlook some seemingly trivial little thing or ignore the >seemingly obvious. > >Like baluns on antenna measurements - just as an example. > Andy You are correct to point out that the experiment must be conducted competently and be reproducable before modifying the theory. However anomolous results can also be of interest. For example, it is not uncommon for researchers to sweep minor, irritating, results under the table. I recall as an undergraduate being taught quantum mechanics by Jocelyn Bell, and I remember it being impressed on us how easily she might have dismissed the anomalous LGM traces as being EMC from a passing police car - certainly that would have been a view readily accepted by the rest of here department. As you probably know she noticed that the "police car" got 4 mins earler each day* and persued the results to discover Pulsars. * A cynic might say that since the probability of police being early is absurd, one could conclude that it was Little Green Men without further investigation :) >I've often found that theory based on back of envelope calculations, made from >first principles, has this annoying habit of often being surprisingly accurate. > > None the less it is always wise to challenge and probe conventional wisdom, and although the instances of it being wrong are rare, I have personal experience (in computer networking) where ignoring such wisdom yeilded important results. 73 Stewart G3YSX >Andy 'JNT > > >-----Original Message----- >From: Stewart Bryant [SMTP:stewart@g3ysx.org.uk] >Sent: 2004/07/23 09:12 >To: rsgb_lf_group@blacksheep.org >Subject: Re: LF: Re: Loops v Verticals > > > >Quite right.

In the past, it was always coherent with other accurate LF-sources. The shift is about .74 Hz +/- .01 Hz downward. It was verified by Markus Vester, DF6NM. Although it could be intentional, I suspect a fault at the transmitting site, with possible consequences to the system 's accuracy. It looks pesistent since yesterday, 22-7. I have tried contacting the site through internet, without success up to now. Does anybody know more, or how to address the site?

Story
I was a technical advisor with the IRAQI airforce during 1957 at RAF Habbaniya and my call was YI2DX. My equipment was a SX28 rx and a modified Collins TCS 6 tx with suitable antennas for all bands. There was a RAF club station YI2AM that I also used, it had a RCA 4336 tx and a SX28 rx plus a few accessories and a lot of big antennas for all bands. There were a couple of other radio amateurs, and we were all kept busy by those chasing YI for DXCC and other awards, especially W6AM and W6HX that wanted a QSO on every HF band.
The California boys were always in hot persuit plus other W stns and others throughout the world.
I also operated mobile around Iraq and apart from Baghdad that I knew very well I operated from Falluagh, Ramadi, Babylon and other places that are now household names with the recent activities that are taking place out there.
The lowest QRG in those days was 160 metres, its a pity we did not have 136 khz !!
When visiting the villages the only way to get food was to get invited into a local house, and the food would be lamb cooked in a variety of ways, with chappati bread. 
I still have a lot of photographs taken in those days, the base at Habbaniya, villages, desert, antennas, operators and the ham shacks.
In the light of recent events perhaps I ought to write a book about bygone days.
de Mal/G3KEV/YI2DX 
PS I still have some QSL cards for those that need one !!!

Actually, that is not strictly true. If an experiment does not agree with theory then both the experiment and the theory need to be re-evaluated and both require validation and revue by a peer group.

Well said Bryan!
 
From my early days in radio I was led to believe an old adage: "Cover the sky with wire!"
 
In what is now almost 50 years of involvement, it still seems to apply and stand me in good stead almost no matter what the wavelength! (And when it comes to antennas [antennae] I still believe in "lens" theory which implies aperture, focii, depth of field and refractive index etc.) A "wave" travelling at the speed of light is presumably subject to the same (or remarkably, similar) physical rules notwithstanding "interpretations" of Maxwell's equations.
At the moment I am struggling to come to terms with the maths of the latest offerings of Penrose and Hawking but as Alan G3Nyk often points out "a good big one usually beats the hell out of even a good small one" in the battle of antennas.
I hope to hell I am not alone in accepting the principle of wave theory, otherwise 50 years of trying to understand radio has just gone up in smoke!

Story
I was a technical advisor with the IRAQI airforce during 1957 at RAF Habbaniya and my call was YI2DX. My equipment was a SX28 rx and a modified Collins TCS 6 tx with suitable antennas for all bands. There was a RAF club station YI2AM that I also used, it had a RCA 4336 tx and a SX28 rx plus a few accessories and a lot of big antennas for all bands. There were a couple of other radio amateurs, and we were all kept busy by those chasing YI for DXCC and other awards, especially W6AM and W6HX that wanted a QSO on every HF band.
The California boys were always in hot persuit plus other W stns and others throughout the world.
I also operated mobile around Iraq and apart from Baghdad that I knew very well I operated from Falluagh, Ramadi, Babylon and other places that are now household names with the recent activities that are taking place out there.
The lowest QRG in those days was 160 metres, its a pity we did not have 136 khz !!
When visiting the villages the only way to get food was to get invited into a local house, and the food would be lamb cooked in a variety of ways, with chappati bread. 
I still have a lot of photographs taken in those days, the base at Habbaniya, villages, desert, antennas, operators and the ham shacks.
In the light of recent events perhaps I ought to write a book about bygone days.
de Mal/G3KEV/YI2DX 
PS I still have some QSL cards for those that need one !!!

Hallo Bryan, Alberto and All,
      let me tell my own experience with an E/H-antenna.
This year on the FRIEDRICHSHAFEN exhibition WIMO offered such antennas. The
advertising text was "like dipole" or "similar to dipole". Whatever that
means.
Coming back I built my own antenna. A rainfall-pipe 16cms Diameter, 70cms
long. The coil on it 23 turns of insulated wire, close together. Another
coil of 2 turns for coupling. At both ends of the pipe a stripe of copper,
1m long, 15cms wide. The stripes are connected to the ends of the coil. This
antenna was put 6meter over ground in free surroundings and fed by RG58. I
could compare it with a dipole by a switch-"click". Frequency is 3,7MHz.
L=107uH (measured), C=17,3pF (calculated).
Results, receiving: The signals are in general 2 to 3 S-stages lower than
from the dipole. That`s normally not so bad, because the noise is also
lower. Signals, that are already very weak with the dipole are not
detectable with the E/H-antenna.
Transmitting: The same, reports are clearly lower than with the dipole. It
is not difficult to make QSO` in CW, but more in SSB.
(Our QRP-friends show every day, how to make QSO`s with 1 to 5w on a dipole,
it`comparable)
I think, this antenna is the opposite of the loop. And its gain can be
compared with the gain of a loop of similar size.
AMA (produces loops) published a diagram. It shows, that the 0.8m-loop on
3,7MHZ has a gain of -18db. Let us assume, that this is realistic. Then
theory matches with the experience.
     Although we all would like to have the very small antenna with 99%
efficiency - the wonder-antenna is not yet at the horizon.
Sorry, the laws of nature are still valid.

Walter,

  thanks for sharing your tests. Your results are in remarkable 
agreement with those
performed by other independent hams, who report abt 18 - 20 dB of loss 
wrt a full
size dipole.
Yes, you are right, the wonder-antenna is not yet at the horizon...

Thanks Alan for the report - nice to know someone's listening! Pretty
poor show as regards activity these days on 136. Afraid I don't have the
time or inclination to spend hours calling CQ to myself, so spend most
of my air time on HF CW.

73, Tom G3OLB

Hello group,

I just read this on Amateur Radio Newsline, the 3rd paragraph is
most interesting: Frequency-Allocations from 0..9 kHz, 70..90 kHz
and 130..190 kHz on LF and also 495..526 kHz. With 3 kW!  

Anyone for a DXpedition? ;-)

73, Fabian, DJ1YFK

THAT FINAL ITEM: SOMALIA GIVES HAM RADIO INCREASED POWER LIMITS

And finally this week, the ARRL Board Meeting was not the only place where 
things were ham radio changes were happening last week.  Another was the 
nation of Somalia which has acted to grant its ham radio population a power 
increase to 3 kilowatts.  Thats right.  We said 3000 Watts and thats 3000 
P-E-P for SSB and 3000 watts average for other modes.  Somalia is also 
letting hams use of the 88 to 108 Mhz band for F-M and permitting Amateur 
Television broadcasts to be conducted on any unoccupied standard VHF or UHF 
television channel.  WIA newscaster Graham Kemp, VK4BB, has more:

--  

Yes the Ministry of Information, Telecommunication and Culture in Somalia 
has made these changes and more as part of action to implement the W-R-C 
2003 accords.

And the Ministry has also made additional frequency allocations for amateur 
radio experimenters in Somalia.  Radio Amateurs in that nation can operate 
on additional bands including Zero to 9 Kilohertz,  from 70  to 90 
Kilohertz and 130  to 190 Kilohertz.  On Medium Wave frequencies include 
495 to 526 Kilohertz, while on the High Frequencies the hams of Somalia get 
5.060 to 5.450 MHz and 26.100  to 29.700 MHz excluding 27.995 the sliver 
band from to 27.999.

This Ministry is promoting Somalia as the best holiday and research 
destination for visiting radio amateurs.  This, as a way of attracting 
skilled people to help the local Somali people become ham radio operators.  
Abdikariim Ali Sulatn in Puntand State Somalia confirmed again that Aussie 
Amateur Sam Voron, 6OA, will continue to conduct ham radio license 
qualifying courses and issue amateur radio licenses free of charge "in the 
name of this Ministry" until a national Somali Amateur Radio Society is 
formed.  

And, oh yes.  If you are planning to go there, a Somali Visitors Amateur 
Radio License is now issued to any class of overseas amateur radio license 
holder as a courtesy.  It is free of charge and issued for life unless 
canceled by the Somali Government.  Talk about an inducement to visit a far 
off land.  

Reporting for the Amateur Radio Newsline, I'm Graham Kemp, VK4BB, for the 
WIA News, in Brisbane, Australia.

--

According to a Somali spokesman, as of now, no other country provides radio 
amateurs with more frequencies or a higher transmitter power output.  He 
added that Somalia welcomes visiting radio amateurs from throughout the 
world.  (WIA News)

I have asked a few questions recently on the reflector and 
have received some good responses. Thank you.

The reason is I am writing a book to be called LF Today, a 
guide to the 136kHz band. It is nearly finished, but I need 
some good pictures for the cover. I am interested in fairly 
high-definition pictures (better than the 72DPI pics that are 
on the web) of LF shacks, interesting spectrograms, loading 
coils and equipment such as transmitters, converters and 
test gear.

Ideally, please send me a low res image as an e-mail 
attachment to: mike.dennison@ntlworld,com, with an 
indication of the file size of the hi-res image. If the picture 
will be used, I will ask for a high resolution image or 
photograph.

Alternatively, send a real photograph to me at:

Thank you.

Hey Mal,
Could you post some of those pics on a server for all of us 
  to see? That would be nice to see some old ham radio pics.

  
Hi Mike

  
I do not have a web page, also picture upload is a very time consuming

You will have to wait for the story book!!

Hi, if this is made by the government of Puntland, that would be a "problem"
as Puntland is a self declared "independent", split-away "country". That
splitted away from Somalia-Mogashishu in the 90s, same as the Republic of
Somaliland (Hargheiza). Both are not recognized by the international community,
which are not valid for the DXCC (except the licences are issued by
the "official" government of "Somalia-Mogadishu"), see Baldur's activity some
years ago (sadly, as the Hargheiza "part" is more or less the only stable and
"secure" region, with the (more or less) only "real" functioning
"administration" inside the territory of the former Somalia.
But in any case, a nice idea indeed. Even when not DXCC relevant it would be a
nice experience ...hi  And any possible QSL would be a nice time historical
dokument ;-)

Greetings,

Um, which Somalia?

http://www.cia.gov/cia/publications/factbook/geos/so.html

I mentioned this to a very dear, worldly and fearless friend, who has been to 
many hair-raising places on missionary and sometimes hambone expeditions, 
including various flavours of Sudan, for example.

He gave a long thoughtful pause, then  -  "I don't think so".

        Cheers,

                Steve

I asked a few weeks ago if anyone knew of a source of 
earthing rods in the UK.

I have now found a source - an electrical supplier with a 
web shop who will deliver. TLC is at
http://www.tlc-direct.co.uk
Screw ended 4ft copper rods are about £10 with double 
ended connectors at £2.60 (both plus VAT). They are a 
trade wholesaler but they appear to sell to anyone over the 
web. There did not appear to be a minimum order.

I suppose these might be easier to drive into some soils but I bought a 3m
length of 20mm copper water pipe from Focus (DIY) for about a fiver last
year...that is a lot more contact area with the soil....but it may be more
difficult to get into the ground if you have layers of flints like I have.
I post augered a hole about 3 foot deep and then created a "guide" hole by
belting in a length of steel conduit. When the pipe was in, the hole was
filled with water to wash the soil ( er sand !!) back around it. I have not
tried to measure yet though.

I am told that an SDS drill is the way to put in earth rods.

Is it undisputed that 3 mtrs 20 mm cu straight down into your flinty stuff
is significantly better than same buried horizontally under the lawn ? [says

Hi Alan & LF Group,

I have almost 6 mtrs of 15 mm straigh down into the soil for one of my earth
points & the way to do it is to connect a hose pipe to the top end & use the
mains water supply to bore down using the water pressure from the pipe to do
the boring, when the firs 3 mtrs is almost at ground level I soldered
another 3 mtr length using a yorkshire pipe coupling & continued in the same
way, it really does work.

Regards

Gary - G4WGT

I suppose these might be easier to drive into some soils but I bought a 3m
length of 20mm copper water pipe from Focus (DIY) for about a fiver last
year...that is a lot more contact area with the soil....but it may be more
difficult to get into the ground if you have layers of flints like I have.
I post augered a hole about 3 foot deep and then created a "guide" hole by
belting in a length of steel conduit. When the pipe was in, the hole was
filled with water to wash the soil ( er sand !!) back around it. I have not
tried to measure yet though.

I asked a few weeks ago if anyone knew of a source of
earthing rods in the UK.

I have now found a source - an electrical supplier with a
web shop who will deliver. TLC is at
http://www.tlc-direct.co.uk
Screw ended 4ft copper rods are about £10 with double
ended connectors at £2.60 (both plus VAT). They are a
trade wholesaler but they appear to sell to anyone over the
web. There did not appear to be a minimum order.

Is an earth mat of radials around the base of a vertical the same as a
single earth rod going to a similar depth?

Hi Brian, Nothing, but Nothing, is undisputed unless you measure it at your
location at 136kHz !! Just coz it might work in my location doesnt mean it
will definitely give the same effects for you. Make a little simple Bridge
to measure R & C in series  
measure an untuned wire. It doesnt have to be the final wire layout, but
something close slung up with "rope insulators" .....they may not stand any
power but the will do to measure. You can then see what kind of developments
you need to get the resistance down. Lay the "radials on the lawn before you
bury them, and if it makes little difference, save the effort, unless of
course you want to work 160m, 80m and 40m, in which case the effort will
most probably pay off up there. You can connect one stake at a time and then
the lawn wires, the mains earth...see what makes the loss-resistance drop
most. When you can't get any more with copper in the ground start puttingit
in the sky as top-load.  I have found you can't get by with guessing on this
topic.

The water trick dont work when you have three strata of flints each about
4inches thick to drive through....its fine on the sandy bits bit but the
pipe is then a bit "loose" and needs to have soil washed round it to bed in.
On a hole dug through the flints (abt 5 foot down) you dont even need water
here, just lean on the pipe and it goes straight in down to 3m...in pure
yellow "building" sand. I am not sure that the stake has much effect in the
sand layer.....but as I said this one has not been measured yet.

Cheers de Alan G3NYK

Thanks for that.
I am well aware that resistance at RF is different from that at DC BUT can
we assume (oops.... justifiably guess) that changes which reduce DC
resistance  to ground also reduce RF resistance to ground, ? I exclude
inductances obviously.

Hi again Bryan, I am not really sure of that one as I have not tried to
correlate the two measurements yet. Genuine DC measurements are fairly
meaningless due to polarisation effects, but some sensible values can be
achieved using low (audio) frequencies, even 50Hz. I suspect that one is
mainly measuring the contact resistance of the system to ground whereas what
is important at LF is the lossy capacitor. There will be some similarity but
I would suggest that reductions seen in the 50Hz value would necessarily be
seen at 136kHz. It all depends on how you measure it. For instance a wire,
insulated from ground, under the top-wire may well reduce the 136kHz loss
without affecting the "DC" value. Connecting to a steel water pipe running
in the opposite direction to the aerial may well reduce the "DC" resistance
without affecting the loss at 136kHz much.

The RF bridge is a useful gadget as it can help you tune and match the
aerial later. A 555 can be used as a drive source, RX as detector. Lloyd
Butler has a full description of a suitable unit at
http://www4.tpgi.com.au/users/ldbutler/LFBridge.htm  His bridge is designed
for the Oz segment at 160 to 180kHz but a slight change in the 555
components will allow to to tune 136kHz. Calibration, always a problem, is
simple with this design, just measure the reference components with the C or
R range on a digital multimeter.
He uses an op-amp to drive the bridge with what is effectivly a floating or
balanced drive. This avoids the effects of stray reactance between the
primary and secondary windings, which affect my simple design if driven
single-ended. You could try using an EMC common-mode choke as a balun. Many
of the EMC ferrite components which are very cheap are usable at LF as
chokes and tranformers, and can often be a cheap way of buying toroids (CPC
or Rapid). One low current common-mode choke I found has a winding
inductance of 50mH and enough window space to wind on a "secondary" which
makes a cheap and adequate (not optimum, as it is beginning to role off at a
few kHz) audio isolation transformer between PC and radio, for less than £1.
It also works well as a low power 600 to 50 ohm transformer at 136khz.

Now's the time to get the aerials sorted for lots of activity in the autumn
(I hope !!)

Cheers de Alan G3NYK

Hello LFers,
some selective levelmeters are without demodulation but with IF-Output, like
the ex GDR MV62 and others. The MC 1496 will do the job. Have not jet built
the productdetector but thought I let you know and comment.

Best regards, Peter, dj9dw.

I was saddened to read the following news on the AMSAT reflector 
today.


Ian was an true LF enthusiast with a presence on both 136 and 
73kHz.  I'm sure we will miss his unique humour and contributions to this 
reflector and his signals from the LF bands.

From RSGB News
Ground-breaking RSGB President, Ian 
Kyle, Silent  Key
Ian Kyle, GI8AYZ and MI0AYZ, the RSGB President in 
1997 and 1998, died  
peacefully at home on Friday the 23rd of July 
after a long illness. Ian was a  
long-serving RSGB volunteer. Joining 
the Society in 1967, he served as a  regional 
representative, Zonal 
Council member, Chairman of the Membership  Liaison 
Committee and 
long-standing GB2RS newsreader and manager. In total Ian  served 
for a 
period of 10 years on the Council. 

A quiet, but persuasive, man, Ian 
will be remembered as the President  who 
during his term in office 
presided over the RSGB change of policy not to  
support compulsory 
Morse testing and for starting the negotiations with the RA -  
now 
Ofcom - which led to the introduction of the Foundation licence. Ian was a  

great supporter and friend of amateur radio in his native Northern Ireland 
and 
across the UK, and was well respected around the world. He will be sadly 

missed  by all those who worked with him and operated with him on the 
bands.

very sad to hear that Ian is no longer with us. Despite his illness he
graciously made the time to show me his great LF setup last year. That top
loading was a work of art, modelled on WWVB I think.

If the IF output is in the audio range, like in some W&G models, another 
option is to feed that IF
to the PC sound card and use my program SDRadio, found at

David,


 


Thanks for conveying the sad news, Ian 
(using GI8AYZ) & I (using G8BQO) had many qso's on 432 Mhz (70 cms) in 
the early 1970's during his many portable outings using 
AM & later years using SSB etc.


 


He will be missed.


 


Gary - G4WGT

  SK.


  
I was saddened to read the following news on the AMSAT reflector 
  today.

  
Ian was an true LF enthusiast with a presence on both 136 and 
  73kHz.  I'm sure we will miss his unique humour and contributions to this 
  reflector and his signals from the LF bands.

From RSGB News
Ground-breaking RSGB President, Ian 
  Kyle, Silent  Key
Ian Kyle, GI8AYZ and MI0AYZ, the RSGB President in 
  1997 and 1998, died  
peacefully at home on Friday the 23rd of July 
  after a long illness. Ian was a  
long-serving RSGB volunteer. Joining 
  the Society in 1967, he served as a  regional 
representative, Zonal 
  Council member, Chairman of the Membership  Liaison 
Committee and 
  long-standing GB2RS newsreader and manager. In total Ian  served 
for 
  a period of 10 years on the Council. 

A quiet, but persuasive, man, Ian 
  will be remembered as the President  who 
during his term in office 
  presided over the RSGB change of policy not to  
support compulsory 
  Morse testing and for starting the negotiations with the RA -  
now 
  Ofcom - which led to the introduction of the Foundation licence. Ian was 
  a  
great supporter and friend of amateur radio in his native Northern 
  Ireland and 
across the UK, and was well respected around the world. He 
  will be sadly 
missed  by all those who worked with him and operated 
  with him on the bands.

Having struggled to find a source of earthing rods, I saw 
some in B&Q today! There are two sorts: about 50mm dia 
and about 25mm dia. Both are copper clad steel, 1.22m 
long with a screw connector included.

I think you can get these from the mail order firm "Screw-fix" as well, the
plated steel dont bend as much as the solid copper, if you have stones (or
flints) in your soil !!

Hi All


I knew Ian for some years and its sad to hear the 
news. He did very well on LF considering his small garden, but he used it to its 
full potential and only used QRP from a modified BK amp. He had been 
in poor health for some time, but in spite of this managed to engineer a 
good signal out on both 73 khz and 136 khz.

The only activity seen this past couple of weeks 
has been F6BWO. Active this morning on 137.7 khz solid O copy also seen last 
week about the same time calling CQ without any response.


It seems LF activity has virtually ground to a 
halt, certainly not worth all the effort to engineer and set up a station these 
days.


The novelty of LF as gone away apart from a few 
stragglers, activity is unlikely to reach the peak of a few years ago when 
the 137 khz band was released to amateurs. 


I listen periodically daytime and early evenings 
and if anyone wants a report I will work xband 7025 khz approx avoiding 
QRM.


mode CW.

don't despair, some of us newbies are looking 
speculatively at the sky and the lawn and working out how to fill each with wire 
and remembering how nice valves are on ye olde LF rx's and studying a tx kindly 
donated by a pundit guru who lives not that far from this bit of Sussex.

Mal 
& LF,


 


If we 
all had that attitude no one would make the effort.


 


I am 
still working on getting the best from my small back garden antenna 
system.


 


I am 
also working on my confidence of returning to CW QSO's after 20 years of 
SSB only.


Also I don't want to be reliant on the personal 
computer for my QSO's although 
in some conditions it is an advantage.


I believe the band is worth the effort, I 
will overcome my key shyness.


 


Regards to Mal & 
All


 


Gary - G4WGT
