Due to my continuing qrn problems at the home qth, I took the opportunity to listen on the big 500 khz transmit antenna at work ( no longer in use except as a reserve receive antenna), today. Heard DF 2 PY at very good strength, sending quite fast cw. The Hagenuk receiver at work (MALIN HEAD RADIO),

does not use an S meter, the signal sounded like a 5 3 9,

very good, full copy, despite the relative high speed, which is faster than most station use with normal morse , on the band.

I would have had no problems, having a full qso with Wolf, pity I did not have a tx , to go back to him.

I'm still working on overcoming the qrn problem, now using a

phasing unit, which I knocked up recently, also building a qrn

canceller by Derek , G3GRO, thanks again to Derek for lthe

circuit diagram and info received this week, It all help.

Saturday 27/2 DF0WD (08.16: 569, 559), HB9ASB (08.56: 559, 329), G6RO (09.26: 589, 599), PA0LQ (10.24: 569, 569), EI0CF (15.43: 589, 529), G3YXM (17.45: 59+9, 59+9). Sunday 28/2 PA0LQ (08.06: 569, 569), DF0WD (08.56: 559, 559), DJ5DI (09.22: 559, 559), MM0ALM (15.14: 559, 559). I re-rigged the antenna on Thursday evening so was ready to go again Friday, despite the heavy rain. The crossband contact with G4BMO in Yeovil was interesting as he reported that I was the first signal he had ever heard on 136kHz; hence my report! I then had to resort to transmitting on 'UHF' (80m) myself to work Finbar, who was still suffering from his noise problem. The band was very busy Saturday morning with plenty of good DX signals about. DF0WD was an excellent signal when I worked him and we had a very solid QSO. Wolf was only running 20W, but said that the club station was located at a football stadium and he had a 200m antenna suspended from the masts! The contact with HB9ASB was a little bit of a struggle - Toni's signal is also very good now when it peaks at around that time, but he was having some difficulty copying me - presumably the noise you reported last week, Toni? Both contacts with PA0LQ were very easy and we chat quite freely these days - it's astonishing just how well Harry does from that apartment..... The good news of the day was that Finbar had found a way to 'cancel out' his local noise and he could copy me again; the first decent 2-way we've had on 136 for several months. Sunday morning conditions were very similar to Saturday. Wolf was a little down on the previous QSO, but we still had a comfortable chat. He asked me if I could copy DF2PY here (yes!) and commented that even he had had problems being heard by DF2PY - no wonder the rest of us get no response! When we had finished, I was called by DJ5DI and we also had a very solid contact, rather better than the first time I worked Fred. During the morning the weather here deteriorated considerably and by mid afternoon a howling gale was threatening to snap my new wire. Consequently, the contact I made with MM0ALM (nr. Aberdeen) was probably the most risky I have made to date on 136 - both the SWR and PA current meters were waving madly from one end of the scale to the other! We made it OK, but I would be interested to know just how much my signal was varying...... Including a few passing comments exchanged with GW4ALG whilst we were chasing DX, that makes 7 countries 2-way in two days of casual operating - who says normal speed CW is out moded??

While testing my transmitter and antenna on Saturday afternoon the loading coil caught fire. One of the windings on the coil had slipped and an arc over occured which caused the plastic insulation to start to burn. This coil has been in place at the base of the antenna for some 18 months now and is dual band 73/136khz so it has done good service. The coil has now been repaired and the antenna current up to 3 amps again. Put out a couple of CQs on SCW on Sunday morning. I did not see any reply and assumed that perhaps my transmitter frequency was too low. Went down to the transmitter shed to retune the transmitter. When I came back I saw a very strong IK1ODO calling me. I dashed back to the transmitter and put it back on the original frequency, came back and gave him an O report. It keeps one fit, this slow CW operating. Got a nice .BMP QSL card from Marco over the e-mail. Was called by DJ5BV (transmitting in a nice clear spot between on .701 nicely between the Loran lines) and we exchanged OO reports. This station passed quite a lot of info during this QSO. I received a cryptic R UFB1STG, which I assumed was a locator that I had not read properly and GERD, which I assume is his name. I just had time to send a R to all this before I had to go QRT. Later I decoded this to ' Received you fine business and you are my 1st G'! I had received a report from a DL on my slow CW transmissions saying that readability was not too good because that the gaps between the morse characters were too short. Andy Talbot G4JNT has kindly modified the program so that the gaps can be increased. I now have the program set up but have yet to try it out on the air. >From Andy > As requested by Peter G3LDO, I have now added a facility to CWSLOW (was > SLOWCW) to increase the inter character gap lengths slightly to improve > readability when using Gram software etc. > For anyone who wants to press an ancient 8086 macine into service - and I > know of at least two using an Amstrad 640 etc - the CWSLOW code is compiled > to the simplest (8 bit ??) form suitable for these machines. -- Regards, Peter, G3LDO From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 21989 invoked from network); 1 Mar 1999 14:49:10 -0000 Received: from magnet.plus.net.uk (HELO magnet.force9.net) (195.166.128.26) by medusa.plus.net.uk with SMTP; 1 Mar 1999 14:49:10 -0000 Received: (qmail 32449 invoked from network); 1 Mar 1999 14:50:43 -0000 Received: from post.thorcom.com (194.75.130.70) by magnet.plus.net.uk with SMTP; 1 Mar 1999 14:50:43 -0000 Received: from troy.blacksheep.org ([194.75.183.50] ident=root) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10HU1q-00085f-00; Mon, 1 Mar 1999 14:50:42 +0000 Received: (from root@localhost) by troy.blacksheep.org (8.6.12/8.6.12) id OAA07240 for rsgb_lf_group-outgoing; Mon, 1 Mar 1999 14:47:05 GMT Received: from post.thorcom.com (root@post.unica.co.uk [194.75.183.70]) by troy.blacksheep.org (8.6.12/8.6.12) with ESMTP id OAA07093 for ; Mon, 1 Mar 1999 14:30:46 GMT X-Priority: 3 X-MSMail-Priority: Normal Received: from mserv1a.u-net.net ([195.102.240.34]) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10HTlj-000733-00 for rsgb_lf_group@blacksheep.org; Mon, 1 Mar 1999 14:34:03 +0000 Received: from rsgb.u-net.com ([195.102.80.225] helo=rsgb.org.uk) by mserv1a.u-net.net with smtp (Exim 2.10 #61) id 10HTiK-0006eK-00 for rsgb_lf_group@blacksheep.org; Mon, 1 Mar 1999 14:30:33 +0000 Received: from miked.rsgbhq [192.168.2.30] by rsgb.org.uk [192.168.2.132] with SMTP (MDaemon.v2.7.SP3.R) for ; Mon, 01 Mar 1999 14:22:29 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 From: "Mike Dennison" Organization: Radio Society of Great Britain To: rsgb_lf_group@blacksheep.org Date: Mon, 1 Mar 1999 14:27:41 -0000 MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII; format=flowed Content-Transfer-Encoding: 8bit Subject: LF: w/e report 27/28 Feb Priority: normal X-Mailer: Pegasus Mail for Win32 (v3.01d) X-MDaemon-Deliver-To: rsgb_lf_group@blacksheep.org Message-ID: Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org Saturday 27 February Heard: GW4ALG (579), HB9ASB (439), G4GVC (599), G6RO (549), G3YMC (429), G3YXM (599).

My name is Des (M0AYF) and am currently a qrp H.F. operator (just a hint of qro :-) with an interest in L.F. I have only been on the mailing list for a few days since I only learned of its existence quite recently. If I may I should like to ask one very important and practical question, is it possible to make contacts effectively at 160 kHz with a proposed antenna which would only be about 25 feet high and about 50 foot long (horizontal wire or "T" resonated against ground) as this is about as much as I could ever manage within the garden of my town semi. In other words are there any operators on the list who are currently working with an antenna system with these sort of dimensions. If so I would very much like to hear from you. I would sooner find out now if my proposed antenna is totally impractical for this wavelength rather than much later on after building up the other components of an LF station. I have been reading the RSGB book "The LF Experimenters Source Book" (page 2.23) which describes a ferrite loaded 73 kHz antenna loading coil. I propose to try something similar for 160 kHz which brings me on to the main subject of this posting. The ferrite I intend to try will be salvaged from some old PC switch mode power supply's of which I have many. Too many in fact (according to the xyl :-( who insists I dispose of as many as possible. I have around 70 of these units free for collection, all are failures and have been condemned as "beyond economical repair" (mostly switching transistor failures) but failed early in their working life so most of them are very clean and dust free. The units strip down very easily and many of the components (not yet failed) are re-usable, these include 12V brushless motor fans with finger guard (good for cooling P.A. or PSU), the all important ferrite cored transformer, 2 x 330 microfarad 200 v capacitors. Fast recovery power rectifiers (low voltage) and various EMC filter components including some yellow/white toroidal cores (about 1 inch dia) which I have used up to 7 MHz as baluns. The cases also make good housings for ham projects ;-) The bottom line is that due to pressure from the xyl I have to get rid of these very, very soon, I could simply arrange for these to go for scrap but hoped that they may find better use with some of you chaps. If anyone living in the region of Gainsborough in Lincolnshire is interested in the above then please drop me a line. Only one catch, you must collect them yourself. Hi Hi :-) Sorry for the bandwidth, I promise I will not make a habit of it. Best wishes and 73's to all "lowfers". Des. Des Kostryca (M0AYF) G.Q.R.P. no. 9788 I.A.R.U. loc. IO93OJ W.A.B.

We /I am looking forward to our getting full use down there at 137 and perhaps at 160 also, from what I have seen your antenna plans will be small but should work. I saw the note on here that U need a -30 DB gain antenna before things began to work Hi. I believe that I have seen sizes like yours that will work, I would check with others on using a ferrite for a loading coil, I believe The coil needs to have as little loss as possible. I dont have the RSGB LF book but will be getting one at the York Pa. Springfest in 2 weeks. To me a loading coil needs to have as high a Q as U can provide, But I have no experience Yet and advice is cheap. 73s Bob K3DJC ___________________________________________________________________ You don't need to buy Internet access to use free Internet e-mail.

Essentially , a _lot_ of RF power will be beamed upwards (sort of a super-duper Luxembourg Effect experiment :-) Although the transmissions are not, at this point in time, directed toward Europe, you may well be able to receive a few sniffs of RF here and there (which almost a megawatt of Tx power...who knows? After all, last month at nags Head, we were hearing European broadcasting stations quite well, with the same kind of power levels). HAARP will be operating almost continuously this month from March 8th through March 27th. Many experiments are being run that concern basic ionospheric research and ELF generation techniques. (Attempts at generation of ELF will be made by pulsing the transmitters). The HAM listening test is of course a CW message sent with full power (960 kW) into the array (15 dB gain). The QSL card is a real nice photo of the array, definitely a collector's item. You may also want to check the ARRL web site for the HAARP listening test schedule.

The band here is 137kHz not 160 kHz - that is the frequency the USA Lowfers have For some months I held the UK distance records for both 73kHz and 137 kHz using a Marconi tee antenna just 7m high with a top span of three wires of 15m. (I think these are roughly equivalent to those American or olde-English 'feet' units of measure you refer to). This size of antenna, fed with 200 Watts or so is more than capable of working up and down the country unless noise levels are particularly high.

Des, Several successful LF operators use small antennas, though it can be frustrating when listening to the big boys working DX. A Marconi T antenna will work well when tuned against a good earth. If you are able to get a light weight loading coil at the top of the vertical section this will help (use a 3 litre coke bottle). You will benefit from running high power - the beauty of the limit being ERP is that you can compensate for an inefficient transmit antenna by increasing power. The BK Electronics amps are useful for instant QRO, though the G3YXM and G0MRF amps are more elegant. Although a basic T will work, there is lots of scope for ingenuity in bending an antenna to get the maximum amount of wire, carrying the maximum amount of current. Mine is triangular! Also, spend as much time on the Rx system as the Tx. The most successful stations can hear well - and there are lots of 'deaf' stations out there - and some of those with smaller antennas have succeded by being able to hear lots of possible QSO partners. You are unlikely to do well from Day One, but patience and persistence in gradually improving your station will bring great rewards. I have twice heard people describe LF contacts from small antennas as "the most exciting in years of operating" and this is my experience, too. My own antenna is bent into 60ft long by 40ft high - bigger than yours but smaller than many - and I have had more than a year of very exciting experimenting, making improvements and ultimately working several countries. Good luck and I look forward to working you. 73 Mike, G3XDV (IO91VT) http://www.dennison.demon.co.uk/activity.htm From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 12872 invoked from network); 3 Mar 1999 10:19:33 -0000 Received: from magnet.plus.net.uk (HELO magnet.force9.net) (195.166.128.26) by medusa.plus.net.uk with SMTP; 3 Mar 1999 10:19:33 -0000 Received: (qmail 27741 invoked from network); 3 Mar 1999 10:21:17 -0000 Received: from post.thorcom.com (194.75.130.70) by magnet.plus.net.uk with SMTP; 3 Mar 1999 10:21:17 -0000 Received: from troy.blacksheep.org ([194.75.183.50] ident=root) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10I8ll-0002P1-00; Wed, 3 Mar 1999 10:20:49 +0000 Received: (from root@localhost) by troy.blacksheep.org (8.6.12/8.6.12) id KAA20474 for rsgb_lf_group-outgoing; Wed, 3 Mar 1999 10:17:14 GMT Received: from post.thorcom.com (root@post.unica.co.uk [194.75.183.70]) by troy.blacksheep.org (8.6.12/8.6.12) with ESMTP id KAA20266 for ; Wed, 3 Mar 1999 10:06:30 GMT X-Priority: 3 X-MSMail-Priority: Normal Received: from mserv1a.u-net.net ([195.102.240.34]) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10I8bE-00010Y-00 for rsgb_lf_group@blacksheep.org; Wed, 3 Mar 1999 10:09:56 +0000 Received: from rsgb.u-net.com ([195.102.80.225] helo=rsgb.org.uk) by mserv1a.u-net.net with smtp (Exim 2.10 #61) id 10I8Xp-0001Vs-00 for rsgb_lf_group@blacksheep.org; Wed, 3 Mar 1999 10:06:26 +0000 Received: from miked.rsgbhq [192.168.2.30] by rsgb.org.uk [192.168.2.132] with SMTP (MDaemon.v2.7.SP3.R) for ; Wed, 03 Mar 1999 10:01:11 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 From: "Mike Dennison" Organization: Radio Society of Great Britain To: rsgb_lf_group@blacksheep.org Date: Wed, 3 Mar 1999 10:06:26 -0000 MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII; format=flowed Content-Transfer-Encoding: 8bit Subject: LF: 73kHz Priority: normal X-Mailer: Pegasus Mail for Win32 (v3.01d) X-MDaemon-Deliver-To: rsgb_lf_group@blacksheep.org Message-ID: Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org Sorry, I missed another 'first Tuesday' on 73kHz.

To Des, and others in the same situation, I say "It certainly is possible!"I too have a small back garden (50 ft x 35 ft), but have worked over 40 different LF stations in 8 countries on 136 kHz - all using normal CW and simple, HF-band-sized antennas. But I'm just one of many amateurs using 'limited space' antennas on 136 kHz. I've even worked Bill G6NB (107 km) when he was using an indoor antenna! I believe that I currently hold the UK distance record (to OH1TN, 1916 km), and also share the intra-UK distance record (703 km) with Dave GM3YXM/P. You'll get lots of encouragement and advice from members of the LF Group to do as well, - and better! It's true that, from a small garden, you won't be able to work every station you hear - but you CAN make contacts, and have a lot of fun too! And you don't need to rely on fancy computerised data links to have DX 'contacts' - just plug in the key, and work 'em!

Would you like to do some tests? Are you ready to receive in slow CW? I may transmit at about any time, but I think that in early morning, around 0600z or so would be the best time for QRN conditions. My ERP is 1W. My best DX is SM6LKM at 1600 km, plus a possible listening by Rik when he was in /EA8. I have several QSO with UK at around 1000-1200 km, and I have the Alps to cross in that direction! In you direction the situation is far better. Let me know.

Although in the first instance I was tempted to use a loop, the body of evidence seems to point to a capacitively-loaded vertical being the better choice. Trouble is, the loop seems to be much easier to get going in the first place and as my antenna experience is mostly confined to the VHF up region, I need some guidance. The antenna configuration I have decided to attempt first is a capacitively-loaded vertical mounted on the roof of the house. This is the only tree-free area on the block. The loading coil I want to place as far up as possible to maximise the current in the vertical part of the antenna. Elevated radials will cover the roof as far as possible around the base of the antenna and connect to surrounding metal roofs, sheds, chook runs and an aviary and also to ground. A picture of this can be found at: http://www.zeta.org.au/~ollaneg/images/AXSO_ant.gif The TX will be connected to the base of the antenna via 50 ohm cable. The questions I have are: 1. How do you measure the capacitance to ground to be able to calculate the inductance of the loading coil? I doubt you can just attach a capacitance meter between the base of the antenna and ground. I am guessing that you just make an estimate and find the required inductance by trial-and-error. 2. Is it possible to connect a smaller *variable* inductance (about 10% of the loading coil inductance) between the base of the antenna and the grounded elevated radials to effect a convenient tuning arrangement? 3. Given the arrangement outlined in 2. above, is it possible to tap into that smaller inductance at the base to effect matching to the 50 ohm line or don't you get the transformer effect required because the major portion of the inductance is elevated and not inductively coupled? Any answers/suggestions would be most appreciated. 73s Steve Olney (VK2ZTO - QF56IK : Lat -33 34 07, Long +150 44 40) ======================================== email: ollaneg@zeta.org.au Web Page: http://www.zeta.org.au/~ollaneg LowFer: http://www.zeta.org.au/~ollaneg/lowfer.htm LF Receiving - FRG-100, 8-turn 10sqm Loop or Ferrite Loop + K0LR Preamp ======================================== From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 8401 invoked from network); 7 Mar 1999 11:48:15 -0000 Received: from magnus.plus.net.uk (HELO magnus.force9.net) (195.166.128.27) by medusa.plus.net.uk with SMTP; 7 Mar 1999 11:48:15 -0000 Received: (qmail 1518 invoked from network); 7 Mar 1999 11:49:51 -0000 Received: from post.thorcom.com (194.75.130.70) by magnus.plus.net.uk with SMTP; 7 Mar 1999 11:49:50 -0000 Received: from troy.blacksheep.org ([194.75.183.50] ident=root) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10Jc4u-0004Nl-00; Sun, 7 Mar 1999 11:50:40 +0000 Received: (from root@localhost) by troy.blacksheep.org (8.6.12/8.6.12) id LAA19361 for rsgb_lf_group-outgoing; Sun, 7 Mar 1999 11:47:08 GMT X-Priority: 3 X-MSMail-Priority: Normal Received: from post.thorcom.com (root@post.unica.co.uk [194.75.183.70]) by troy.blacksheep.org (8.6.12/8.6.12) with ESMTP id LAA19266 for ; Sun, 7 Mar 1999 11:26:04 GMT Received: from nms.rz.uni-kiel.de ([134.245.1.2]) by post.thorcom.com with smtp (Exim 2.04 #3) id 10JbkO-0002xt-00 for rsgb_lf_group@blacksheep.org; Sun, 7 Mar 1999 11:29:28 +0000 Received: from mail.uni-kiel.d400.de (actually srv1.mail.uni-kiel.de) by nms.rz.uni-kiel.de with Local-SMTP (PP); Sun, 7 Mar 1999 12:25:32 +0100 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from nephro.uni-kiel.de by mail.uni-kiel.d400.de (SMI-8.6/SMI-SVR4) id MAA19160; Sun, 7 Mar 1999 12:25:30 +0100 Message-ID: <36E2623C.8D584AE@nephro.uni-kiel.de> Date: Sun, 07 Mar 1999 12:25:48 +0100 From: "Peter W.

Agreed! What`s about your trial with the "Monster Antenna" ? Unfortunatly the Great Circle to USA from here is running straight over the next LORAN-C transmitter. But we could try to (citation...) "read between the lines". Dec. 12th 2001 is far and Guglielmo Marchese Marconi made it with 20kw on 300kHz, but we have better RX.

The monster antenna is in fact a copy of the Goliath. 1200 ft tall, with a top capacitance rumored to be somewhere around 0.05 uFd (?). It is presently grounded for obvious reasons and, although we could unground it, we are afraid that none of the equipment we own, and could connect to that antenna, could possibly survive any kind of static charge. (in fact we could ourselves get fried quite easily...) Hence we have decided to leave that vertical stick alone, and connect ourselves instead to a couple of Marconis ("T") that were originally cut to resonate around 134 kHz. They terminate in small rooms, with electrical power available. These Marcoonis are quite impresssive, and we shall use them, among other things, to try and determine the relative gain, and noise floor, of an e-field probe versus a "T" against a known source, for instance a local Medium Wave (known here as "AM") transmitter on 1500 kHz . 73 Andre' From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 16655 invoked from network); 8 Mar 1999 08:49:26 -0000 Received: from magnus.plus.net.uk (HELO magnus.force9.net) (195.166.128.27) by medusa.plus.net.uk with SMTP; 8 Mar 1999 08:49:26 -0000 Received: (qmail 26266 invoked from network); 8 Mar 1999 08:51:06 -0000 Received: from post.thorcom.com (194.75.130.70) by magnus.plus.net.uk with SMTP; 8 Mar 1999 08:51:06 -0000 Received: from troy.blacksheep.org ([194.75.183.50] ident=root) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10Jvl9-0004bW-01; Mon, 8 Mar 1999 08:51:35 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: (from root@localhost) by troy.blacksheep.org (8.6.12/8.6.12) id IAA29415 for rsgb_lf_group-outgoing; Mon, 8 Mar 1999 08:47:42 GMT Received: from post.thorcom.com (root@post.unica.co.uk [194.75.183.70]) by troy.blacksheep.org (8.6.12/8.6.12) with ESMTP id IAA29293 for ; Mon, 8 Mar 1999 08:20:15 GMT X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from irwell.zetnet.co.uk ([194.247.47.48] ident=root) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10JvKE-0001n9-00 for rsgb_lf_group@blacksheep.org; Mon, 8 Mar 1999 08:23:46 +0000 Received: from central.zetnet.co.uk (central.zetnet.co.uk [194.247.47.20]) by irwell.zetnet.co.uk (8.9.3/8.9.3/Debian/GNU) with SMTP id IAA30745 for ; Mon, 8 Mar 1999 08:19:59 GMT X-ZSender: g3ldo@zetnet.co.uk Message-ID: <1999030808234568199@zetnet.co.uk> Date: Mon, 8 Mar 1999 08:23:45 GMT To: rsgb_lf_group@blacksheep.org From: "Peter Dodd" X-Mailer: ZIMACS Version 1.20c 10000836 Subject: LF: Re: 6/7th March Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org Content-type: text/plain; charset=windows-1252; format=flowed MIME-Version: 1.0 Content-transfer-encoding: 8bit Worked DL0YE at JO54NG on Saturday Put out a CQ on Sunday morning at around 0815UT and saw "WV K on .706 Also another station on my own frequency which I could not copy because of a Loran line Tried another CQ and back came IK1ODO with a very strong signal nicely between the Loran lines.

What weather??!!! At least everything got so absolutely soaked that the antenna tuning stayed constant....... Stations worked on 136kHz using normal speed CW: Friday 5/3 GW4ALG (20.21UT: gave me 599QRN/QSB, he was 57/89QRN), G8RW (20.38: 579QRN, 579QRN). Saturday 6/3 PA0LQ (10.22: 569, 569). Sunday 7/3 DF0WD (08.30: 559, 559), G6RO (09.40: 589, 59+9), G3YXM (10.22: 59+9, 59+9), PA0LQ (11.44: 569, 469QRN). The rain started on Friday evening and the band was very noisey indeed with static crashes, so I was pleased make my first QSO with Bob, G8RW in Bromley. He has a very good signal for a newcomer to the band. Having got up fairly early on Saturday morning, I was not pleased to find snow falling heavily, with my loading coil bin already covered and the wire double its normal thickness! By mid-morning there was a couple of cm of the stuff everywhere and the band sounded very 'strange' on receive. I managed a good QSO with Harry, but activity was extremely low all day. By Sunday the snow had turned back to rain.....and more rain......and...... The bottom of our garden was now under several cm of water and I was uneasy about loading up the wire, but everything seemed OK with no sign of any arcing. Another good QSO with DF0WD confirmed all was well. My major event of the weekend came a little later at 09.16UT when I found a signal calling on 136.9kHz, which turned out to be I5MXX, peaking RST-559. I quickly called back, but when I went over to receive, there instead was DF2PY rattling away with one of his never-ending CQ calls - argh! So that, as they say, was that........ Later I had another contact with PA0LQ, but the contact was harder than usual because he was suffering with noise from a local light dimmer, and half way through the contact..... yes, DF2PY started calling CQ on almost the same frequency! Is anyone else getting alarmed at the number of stations (in all countries) who are starting to appear on the band with good signals but mediocre or even atrocious receive systems? It's relatively easy to build (or buy, now) an effective LF transmitter, but how can we encourage people to work on their receive systems and ensure they can receive as well as they radiate? An interesting challenge in education for sure.

The lower part (7m) is a PVC irrigation pipe (11cm Diameter) the upper part a Kevlar fishing pole (8m). I've wound about 350m of Liz wire on it. Top load is a 60m long wire going up to 18m and then down to 8m, zigzag over my 30*40m property. Self resonance of the whole thing is around 170 kHz and I match it to the coax via an autotransformer (abt. 1mH), wound on a plastic waste-paper basket. For comparison I've built exactly the same antenna a few meters away but with a straight wire instead of the helical. The helical was always 3 or more dB's better, on transmit and on reception. I think the helical is good for some more dB's if you can make the diameter larger (a handling problem, hi). 73 de Toni Bob RIESE schrieb: > > Has anyone done anything with a continuously loaded vertical and top hat. > 40 Ft of large diameter plastic pipe wound with copper wire would be a > rubber duckie on LF, the only problem I see would to keep it from acting > like a Tesla Coil > > Bob K3DJC > ___________________________________________________________________ > You don't need to buy Internet access to use free Internet e-mail. > Get completely free e-mail from Juno at http://www.juno.com/getjuno.html > or call Juno at (800) 654-JUNO [654-5866] From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 2418 invoked from network); 8 Mar 1999 21:18:24 -0000 Received: from magnet.plus.net.uk (HELO magnet.force9.net) (195.166.128.26) by medusa.plus.net.uk with SMTP; 8 Mar 1999 21:18:24 -0000 Received: (qmail 22666 invoked from network); 8 Mar 1999 21:20:38 -0000 Received: from post.thorcom.com (194.75.130.70) by magnet.plus.net.uk with SMTP; 8 Mar 1999 21:20:38 -0000 Received: from troy.blacksheep.org ([194.75.183.50] ident=root) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10K7Sd-0001I4-00; Mon, 8 Mar 1999 21:21:15 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: (from root@localhost) by troy.blacksheep.org (8.6.12/8.6.12) id VAA05345 for rsgb_lf_group-outgoing; Mon, 8 Mar 1999 21:17:49 GMT Received: from post.thorcom.com (root@post.unica.co.uk [194.75.183.70]) by troy.blacksheep.org (8.6.12/8.6.12) with ESMTP id VAA05195 for ; Mon, 8 Mar 1999 21:08:51 GMT Received: from mars.cableol.net ([194.168.4.224]) by post.thorcom.com with smtp (Exim 2.04 #3) id 10K7Jc-0000Pu-00 for rsgb_lf_group@blacksheep.org; Mon, 8 Mar 1999 21:11:56 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from larissa-85.cableol.net by mars.cableol.net; (5.65v3.2/1.1.8.2/22Feb96-0403PM) id AA19169; Mon, 8 Mar 1999 21:08:16 GMT Message-ID: <36E43A22.69278378@cableol.co.uk> Date: Mon, 08 Mar 1999 20:59:14 +0000 From: "Steve Rawlings" X-Mailer: Mozilla 4.04 [en] (Win95; I) MIME-Version: 1.0 To: "LF Group" Subject: LF: Weekend Report 6-7/3/99, GW4ALG Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 8bit Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org Hi All, I got the balloons up again on Saturday morning and thus extended my 12 m vertical into a 20 m vertical for 136 kHz. At 06:42 UTC, I had a fine QSO with Harry PA0LQ (RST 559 both ways). At 07:40, club station DF0WD (768 km) answered my CQ call and we made the first DL/GW 2-way QSO on 136 kHz (I sent RST 449, received 349). DF0WD, operated by Wolf DL4YHF, was running 20 W to a 200 m wire, 17 m high ("tied to the light-masts of a football field"). In a subsequent Email, Wolf described his RX antenna as a small bundle of ferrite rods and said "I have to turn that antenna by hand to get minimum QRM (not maximum field-strength of the received signal!)." The weather got windy later on, so I took the experimental vertical down. On the loop I had a QSO with Ron G6RO (253 km, 549 both ways) and in the afternoon I worked Bob G8RW (192 km) for a new one (I sent RST 459, received 539). On Sunday, I got the balloons up again to work Harry PA0LQ at 07:08 UTC (549 both ways). With a large number of jobs to do around the house at weekends, I expect to be most active on Saturdays and Sundays between 06:30 and 08:00 (local time). This is also when the weather conditions are most likely to be favourable for using my balloon-supported vertical.

GREETINGS LF GROUP.

I HAD THE OPPORTUNITY TO OPERATE FROM A QRN FREE SITE ON FRIDAY 5TH MARCH.

MADE SEVERAL CALLS DURING THE DAY FROM 1130 UTC , HOWEVER I WORKED MY FIRST LF STATION OF THE DAY AT 1505 UTC. HERE IS THE LIST OF STATIONS WORKED.

1505 TO 1526 G3RXH HOWARD QTH SKIPTON ( HIS 2ND LF QSO) RST 439 ME 589.

1545 TO 1550 DF3LP PETER QTH KIEL RST 429 ME 349

1556 TO 1603 DL0YE PETER QTH UNKNOWN. RST 429 ME 449

1612 TO 1617 G0UPU NO INFO RST 329 ME 569

1625 TO 1634 GW3XYW STUART QTH SWANSEA RST 559 ME 549.

THIS OPERATION WAS WELL WORTH IT AS I MADE MY FIRST, AND THEN SECOND LF/LF

CW QSO WITH GERMANY.

WHAT A DIFFERENCE WORKING FROM A QRN FREE SITE MAKES.

AFTER 1645 THE BAND GOT INCREASINGLY BAD FROM STATIC CRASHES AND I

HAD TO CLOSE DOWN OPEATIONS.

MY HOME QTH NOISE PROBLEM SEEMS TO HAVE GOT WORSE, OVER THE WEEKEND, I

REDUCED THE SIZE OF MY ANTENNA, TO SEE IF I WAS GETTING MORE QRN FROM RUNS OF WIRE IN DIFFERENT DIRECTIONS.........HAD NO EFFECT. IN FACT I SPENT THE WHOLE WEEKEND MAKING A LAST DITCH EFFORT TO CURE THE PROBLEM, TO NO

EFFECT. THE FINAL RESULT WAS TO TAKE DOWN ALL THE LF ANTENNA SYSTEM.

I AM OFF THE AIR ON LF FROM MY HOME QTH, UNTIL I GET A COMPLETE CURE FOR THE NOISE, THE ONLY OPERATION I CAN MAKE NOW IS FROM THE QRN FREE SITE AT WORK,

THIS IS NOT EASY TO ARRANGE, AS YOU CAN UNDERSTAND.

JOHN /G4GVC HAS MADE A VERY GOOD POINT ABOUT STATIONS PUTTING OUT GOOD SIGNALS BUT BEING UNABLE TO HEAR VERY WELL. I CAN UNDERSTAND THIS, AS I DEVELOPED A GOOD TRANSMIT SIGNAL BUT IN RECENT TIMES HAVE BEEN UNABLE TO HEAR ANYTHING ON 136 KHZ. THERE IS NO POINT IN TRANSMITTING BLIND AND FOR LONG PERIODS IF ONE CAN NOT MONITOR THE BAND. OTHERWISE ONE IS IN DANGER OF SPOILING IT FOR OTHERS. THIS IS ONE OF THE PROBLEMS FOR SOMEONE LIKE ME

WHO HAS TRIED CROSSBAND WORKING TO 80M TO OVERCOME THE QRN ON 136KHZ.

I MAY IN THE PROCESS BE BLOTTING OUT AN LF QSO WITHOUT KNOWING IT.

THERE MAY BE A POINT IN HAVING LOW POWER BEACON TYPE TRANSMISSION'S ON THE BAND , PERHAPS AT THE LOWER BAND EDGE. CERTAINLY A STEADY SIGNAL

CAN BE A GREAT AID TO TUNING UP AND WORKING ON A RECEIVE SYSTEM.

THANKS AGAIN TO ALL MEMBERS OF THE LF GROUP FOR ALL THE HELP WITH MY

QRN PROBLEM.

IT LOOKS LIKE I WILL BE ABLE TO OPERATE FROM MY QRN FREE SITE NEXT FRIDAY

12TH MARCH , TIME APPROX 1100 UTC TO 1700 UTC, ANYBODY WHO WANTS TO ARRANGE A SKED , LET ME KNOW PLEASE.

It's relatively easy to build (or buy, now) an effective LF transmitter, but how can we encourage people to work on their receive systems and ensure they can receive as well as they radiate? An interesting challenge in education for sure. >> Yes, but I do have some sympathy as I've been there myself. In my case, my receiver was deaf as a post at 136. In fact from measurements the Icom 756 is an order of magnitude worse than other receivers. Even my first attempt with a receive converter suffered from excessive local oscillator leakage which caused de-sense. Thankfully, with help from this reflector, the problems were identified and overcome and now it's mainly local noise and antennas which limit performance. Both DF2PY and LX1PD have very strong TX signals, and like many of us in the early days, would probably be beaconing away for hours for reports if band occupancy was lower. (Actually it must seem like that for them) I guess the only solution is for local stations to disseminate information and encourage improvements in RX performance. I note that neither are on the reflector. The problems across the channel seem to be related to noise and intermod's rather than sensitivity perhaps some of the noise reduction techniques that have been developed could be added to a web site so that this information could be more widely accessed. We may also need a translation or two so that any techniques developed become pan-European At least hard copy could be posted to those not on the net! I suppose after a reasonable period of time it's going to be: pse QSY frequency in use. Oh dear, sounds like CQWW! 73 David From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 23525 invoked from network); 9 Mar 1999 08:18:14 -0000 Received: from magnus.plus.net.uk (HELO magnus.force9.net) (195.166.128.27) by medusa.plus.net.uk with SMTP; 9 Mar 1999 08:18:14 -0000 Received: (qmail 23797 invoked from network); 9 Mar 1999 08:19:59 -0000 Received: from post.thorcom.com (194.75.130.70) by magnus.plus.net.uk with SMTP; 9 Mar 1999 08:19:59 -0000 Received: from troy.blacksheep.org ([194.75.183.50] ident=root) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10KHl8-0007ZL-01; Tue, 9 Mar 1999 08:21:02 +0000 Received: (from root@localhost) by troy.blacksheep.org (8.6.12/8.6.12) id IAA10417 for rsgb_lf_group-outgoing; Tue, 9 Mar 1999 08:17:16 GMT X-Priority: 3 X-MSMail-Priority: Normal Received: from post.thorcom.com (root@post.unica.co.uk [194.75.183.70]) by troy.blacksheep.org (8.6.12/8.6.12) with ESMTP id HAA10315 for ; Tue, 9 Mar 1999 07:53:24 GMT Received: from server.italway.it ([193.70.27.5] ident=root) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10KHNn-0005Z5-00 for rsgb_lf_group@blacksheep.org; Tue, 9 Mar 1999 07:56:55 +0000 Received: from a (ppp4.italway.it [193.70.27.53]) by server.italway.it (8.9.3/8.9.3) with SMTP id IAA24519 for ; Tue, 9 Mar 1999 08:45:43 +0100 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Message-ID: <1.5.4.32.19990309080052.006dd83c@server.italway.it> X-Sender: yasmin@server.italway.it X-Mailer: Windows Eudora Light Version 1.5.4 (32) MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit Date: Tue, 09 Mar 1999 09:00:52 +0100 To: rsgb_lf_group@blacksheep.org From: "Yasmin Tour Agenzia Viaggi" Subject: Re: LF: looking for italians lf-operators e-mail Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org Ciao Rudy.

There is nothing that says that my receiver has _got_ to be located next to my transmitter, is there?
Over here, we are considering finding a qrn-free site, equipping it properly with a good receiver, taking the whole 2 kHz band and redistributing to all the members, either on a FM repeater, or on the internet.
This won't happen probably until the fall, as we are first trying to put a transmitter on the air!

LF natural noise levels (QRN) are typically well above the front end noise in good receiving gear, and there is not much that can be done to improve matters further. The QRN likely originates from lightning in the atmosphere. Use of a whip/loop phased array producing a carioid pattern can improve S/N a little if the atmospheric noise is mainly from directions well away from the signal angle of arrival (as verified by Andrew ZL2BBJ and Nat ZL3VN, who regularly use phased systems for receiving amateur LF signals) On the other hand, man made noise (QRM) can be a real pain in the rear end when trying to receive weak LF signals. Keeping as far as is practicable away from mains power seems to be the best countermeasure. A well decoupled power supply to an active whip sited down the backyard can give quite good relief from mains borne QRM at LF.

Sounds like a great idea -particularly over the internet!

Mike Staines WA1PTC has the audio from his IC735 available via his web site (at http://mike.nh.ultranet.com/htm/monitor.html).

His receiver is also remotely tuneable -which may be worth looking at if the broadband idea proves incapable of handling the necessary dynamic range without intermod problems.

I've not heard of anyone this side of the Atlantic transmitting whilst listening to Mike's RX via the Internet -but I'm sure someone will have tried it.

There are generally quite a few seconds of audio buffered to allow for Internet propagation delays -but that wouldn't be much of an issue with very slow CW!

Best of luck with the project.

Hello LF Gang,
There is nothing that says that my receiver has _got_ to be located next to my transmitter, is there?
Over here, we are considering finding a qrn-free site, equipping it properly with a good receiver, taking the whole 2 kHz band and redistributing to all the members, either on a FM repeater, or on the internet.
This won't happen probably until the fall, as we are first trying to put a transmitter on the air!

It took Wolf and me several hours to find solutions and we have made great progress in Wolf´s ability to copy weak stations now One of the main problems was receiver front end overload (FT1000) caused by LF transmitters in this area. After adding some of the major necessary mods Wolf was able to see on screen (using my PC) and also hear stations from the UK, HB9 and DL which otherwise were not audible/visible. However, one of our biggest problems in this area remains unsolved: sideband-splatter from DLF (on 153 kHz) during periods of 100 % modulation. The band around 137 kHz is covered with about 10...12 db of hash noise which of course completely covers any weak signals which might be there... I am currently trying to find an elegant way how to convince the engi- neers at the DLF transmitter site to help us.... I have several recordings available as Bitmap-files showing this problem (in case someone is interested in seeing them). Stations in the UK are living with the LORAN-C sidelines but they can hear between the lines. Stations in DL in this area (Rhein-Main-Neckar region) have to live with the hash noise. But this is everywhere and there is even more "unfriendly" stuff from the LF transmitter site at Mainflingen. I hope you all see the efforts we are making in this area to improve the reception of weak signals on LF.

I had many skeds with Toni to try and get a signal to HB9 on 73kHz but nothing ever came of it. On Monday night (8th March), at 2100UT we tried again, this time with the aid of Spectrogram and Toni e-mailed back an 'O' report. Last night (9th March) this was converted into a 2-way LF cross-band QSO with Toni on 137.68 and myself on 73.23kHz. The QSO went well in spite of my 136 receiver loop not being very efficient. To complicate matters a signal came up on Toni's frequency with '569 ASBK', which I interpreted as my 73kHz signals were being heard by Toni. This prompted me to try fast CW, which ended in nothing. Fortunately we had already exchanged 'O' reports in SCW. As I write I am just finishing a successful two-way SCW 136kHz QSO with IK5ZPF, 'O' both ways. -- Regards, Peter, G3LDO From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 18855 invoked from network); 10 Mar 1999 12:47:28 -0000 Received: from magnet.plus.net.uk (HELO magnet.force9.net) (195.166.128.26) by medusa.plus.net.uk with SMTP; 10 Mar 1999 12:47:28 -0000 Received: (qmail 17373 invoked from network); 10 Mar 1999 12:49:53 -0000 Received: from post.thorcom.com (194.75.130.70) by magnet.plus.net.uk with SMTP; 10 Mar 1999 12:49:53 -0000 Received: from troy.blacksheep.org ([194.75.183.50] ident=root) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10Kg6a-0007hc-01; Wed, 10 Mar 1999 10:20:48 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: (from root@localhost) by troy.blacksheep.org (8.6.12/8.6.12) id KAA22867 for rsgb_lf_group-outgoing; Wed, 10 Mar 1999 10:17:15 GMT Received: from post.thorcom.com (root@post.unica.co.uk [194.75.183.70]) by troy.blacksheep.org (8.6.12/8.6.12) with ESMTP id JAA22751 for ; Wed, 10 Mar 1999 09:57:50 GMT Received: from dub-img-11.compuserve.com ([149.174.206.141]) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10Kfng-0005V2-00 for rsgb_lf_group@blacksheep.org; Wed, 10 Mar 1999 10:01:16 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: (from root@localhost) by dub-img-11.compuserve.com (8.8.6/8.8.6/2.18) id EAA12056 for rsgb_lf_group@blacksheep.org; Wed, 10 Mar 1999 04:57:08 -0500 (EST) Date: Wed, 10 Mar 1999 04:54:15 -0500 From: "Howard Aspinall" <100646.144@compuserve.com> Subject: LF: Deaf receivers To: rsgb_lf_group@blacksheep.org Message-ID: <199903100456_MC2-6D6D-49D@compuserve.com> MIME-Version: 1.0 Content-Transfer-Encoding: 8bit Content-Type: text/plain; charset=us-ascii; format=flowed Content-Disposition: inline Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org Greeting all My first posting to this list though I've been receiving mesages for some months, and also listening on 136 KHz since the band came available in the UK. On the subject of receivers, for a long time I used a Trio TS430 which was very deaf indeed on 136, made worse by an indifferent aerial...a base loaded 100 ft sloper the top being 80ft agl. With a tx under construction (valve job) it seemed appropriate to look at getting a better rx, and having as another interest the collection of vintage radio gear, I turned to what I had. Some might remember the AR88LF, an old valve rx which tunes down through 136 to 73 KHz, but which has poor if skirt selectivity (by modern standars). Also the Racal RA17 which doesn't go much below 500 KHz, but which has a nice 100 Hz bandwidth crystal filter. By taking an o/p at intermediate frequency from the AR88, and feeding it into the RA17 tuned to that frequency, what seems like a very good rx system emerged. In effect the AR88 has become a tunable converter. The result is that I can hear very much more than I can work, though perhaps the 85 watts or so rf o/p from the tx is too modest. Suffice it to say that on 4 March I was receiving OH1TN calling cq at a nice 559 though he couldn't hear my puny signal and no one else was heard calling him whilst I was listening. My rx system can hardly be described as hi tech, but it does the job (though isn't exactly portable), and anyone with an old rx covering the 136KHz band might care to consider a similar arrangement, perhaps using more modern gear as an if amp/detector. When I heard OH1TN, the aerial was a 240 ft inverted vee with apex at 80 ft agl inductively loaded at the feed point. Since then it has been changed to a triangular loop with the loading coil at the far end of the inverted vee from the feed point, resonated with a series vacuum variable cap to a return wire trailing on the ground back to the feed point. Initial reception tests suggest a worthwhile (and anticipated) improvement over the original base loading arrangement. Maybe further improvements can be made with it as experience/knowlege of lf techniques is gained. Incidentally, as an aside, when listening to 136 at night, I sit in near darkness, since it soon became clear the energy efficient bulbs used in the shack were producing a nasty rf noise blanking all but the stronger signals. 73..Howard/G3RXH From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 19902 invoked from network); 10 Mar 1999 12:49:01 -0000 Received: from magnus.plus.net.uk (HELO magnus.force9.net) (195.166.128.27) by medusa.plus.net.uk with SMTP; 10 Mar 1999 12:49:01 -0000 Received: (qmail 17543 invoked from network); 10 Mar 1999 12:49:19 -0000 Received: from post.thorcom.com (194.75.130.70) by magnus.plus.net.uk with SMTP; 10 Mar 1999 12:49:19 -0000 Content-Transfer-Encoding: 8bit Received: from troy.blacksheep.org ([194.75.183.50] ident=root) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10KiRx-0004E2-01 for dave@picks.force9.co.uk; Wed, 10 Mar 1999 12:51:01 +0000 X-Priority: 3 Received: (from root@localhost) by troy.blacksheep.org (8.6.12/8.6.12) id LAA23310 for rsgb_lf_group-outgoing; Wed, 10 Mar 1999 11:20:10 GMT X-MSMail-Priority: Normal Received: from post.thorcom.com (root@post.unica.co.uk [194.75.183.70]) by troy.blacksheep.org (8.6.12/8.6.12) with ESMTP id LAA23250 for ; Wed, 10 Mar 1999 11:17:36 GMT Received: from server.italway.it ([193.70.27.5] ident=root) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10Kh2n-0004Bf-00 for rsgb_lf_group@blacksheep.org; Wed, 10 Mar 1999 11:20:58 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from a (ppp6.italway.it [193.70.27.55]) by server.italway.it (8.9.3/8.9.3) with SMTP id MAA06435 for ; Wed, 10 Mar 1999 12:09:27 +0100 Message-ID: <1.5.4.32.19990310112439.006d9224@server.italway.it> X-Sender: yasmin@server.italway.it X-Mailer: Windows Eudora Light Version 1.5.4 (32) MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii; format=flowed Date: Wed, 10 Mar 1999 12:24:39 +0100 To: rsgb_lf_group@blacksheep.org From: "Yasmin Tour Agenzia Viaggi" Subject: Re: LF: Re: ei to i Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org Dear Finbar, I would like to precise something about our cross band qso of some weeks ago. I sure copied your signals on 136, including your receiving frequency on 80 metrs and your report to me, and you copied my signals to you. But, unfortunately, I DIDN'T copy your full call, but only I0CF. I was, infact, persuaded to work a weak ( conventional cw) Italian hams in a deep sea a of qrm and qrn, until G3YXM, Dave, write me the day after about the mistake.... So, technically speaking, both signals has been received each other, but ethically speaking our qso is INVALID . I am very sorry for this missed opportunity, but ,anyway, I am sure we can replace it in short time, cross band or two way as you can find a qrn free site.

Maximum allowed transmitter output is 400 W; only CW (A1A). My station is located at Leiderdorp, a town adjacent to the university town of Leyden. The QTH is 40 km SW of Amsterdam and 12 km from the North Sea coast. Transmitter output is about 100 W, of which 45 milliwatt is radiated, as determined by measuring the field strength at 1 km distance from the station. I have worked DJ5DI, DK9DX, DJ5BV, DF0WD, G3LDO, G3GRO, G3YXM, G3KAU, G3WSC, GB4RS, G4XTZ, G4GVC, G4HYM, G3KEV, G4WMZ, G3XDV, G3OLB, GW4ALG, GM3YXM/P, ON4ZK, ON7YD, ON6ND, PA0LQ, PA0CWF, PA0MLC, PA0SSB, PA0DSW, PA0CC, PA2NJN. My urban location is a bit noisy, mainly local QRM and a bit of LORAN. But I just finished contruction of a 4-pole audio filter, centre frequency 1000 Hz and with only 35 Hz bandwidth. It is a phase linear design which means that it does not ring. Maximum CW speed that can be passed seems to be about 24 wpm; more than the operator can handle! The filter was designed by Harry Grimbergen, PA0LQ, using a combination of info from "Reference Data for Radio Engineers" and computer simulation. I hope the filer will help in copying weak signals in teh noise. The same result, or maybe an even better one, could have been achieved by an external DSP unit between receiver and headphones or software in the computer. But these solutions must be bought and I like to make it myself. I am available for skeds (hand-keyed morse only) almost any day and time. Evening hours are to be avoided because man made noise is then unreasonably strong. 73 from Dick D.W. Rollema, PA0SE V.d.

I've tried also two other antennas while Peter, G3LDO, called me. The first is a tuned loop nailed on the wall of my shack, 16 turns with about 2m diameter and oriented north-south. The second is an untuned active Loop, away from the house in a garden shelter. It has about the same diameter and orientation. The loop in the shack was useless. It picks up too many RF from my computer, but I could see Peter's signal on the loop in the garden. Not as good as on the helical, but with the advantage that I could receive on 73 during my transmission on 136khz without any disturbances - full duplex! I also have to say, that the 73khz Band is very quiet here. There is no Luxembourg - Effect as on 136. The receiver was the Harris RF590. The AF goes trough the Timewave DSP599 where I use it's noise reduction algorithm before feeding the sound card of the computer. This gives a considerable additional noise reduction! So far I've tried different receivers for the LF work, besides some brands of commercial receivers also amateur equipment. The problem with many amateur transceivers is, that they have a built in attenuation pad for the LF/MF range, so they are quite deaf down there. If you're not living in proximity of a MF/LF broadcast station you don't need this attenuator. It's easy to locate on the schematic diagram. It's often right in front of the LF/MF low pass filter and I've eliminated it in different "Yen Boxes" without any problem. 73 de Toni From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Content-Type: text/plain; charset=iso-8859-1; format=flowed Return-Path: Content-Transfer-Encoding: 8bit Received: (qmail 7346 invoked from network); 11 Mar 1999 15:20:07 -0000 Received: from magnet.plus.net.uk (HELO magnet.force9.net) (195.166.128.26) by medusa.plus.net.uk with SMTP; 11 Mar 1999 15:20:07 -0000 Received: (qmail 27907 invoked from network); 11 Mar 1999 15:22:40 -0000 Received: from post.thorcom.com (194.75.130.70) by magnet.plus.net.uk with SMTP; 11 Mar 1999 15:22:40 -0000 Received: from troy.blacksheep.org ([194.75.183.50] ident=root) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10L7Gb-0006SZ-01; Thu, 11 Mar 1999 15:20:57 +0000 X-Priority: 3 X-MSMail-Priority: Normal Received: (from root@localhost) by troy.blacksheep.org (8.6.12/8.6.12) id PAA03012 for rsgb_lf_group-outgoing; Thu, 11 Mar 1999 15:17:25 GMT Received: from post.thorcom.com (root@post.unica.co.uk [194.75.183.70]) by troy.blacksheep.org (8.6.12/8.6.12) with ESMTP id OAA02858 for ; Thu, 11 Mar 1999 14:51:11 GMT Received: from alpha1.dii.unisi.it ([193.205.7.2]) by post.thorcom.com with smtp (Exim 2.04 #3) id 10L6qx-00035X-00 for rsgb_lf_group@blacksheep.org; Thu, 11 Mar 1999 14:54:28 +0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: by alpha1.dii.unisi.it id AA20833; Thu, 11 Mar 1999 15:50:44 +0100 Received: by pcfasec.dii.unisi.it with Microsoft Mail id <01BE6BD7.7F699880@pcfasec.dii.unisi.it>; Thu, 11 Mar 1999 15:54:51 +0100 Message-ID: <01BE6BD7.7F699880@pcfasec.dii.unisi.it> From: "Valerio Gabbani" To: rsgb_lf_group@blacksheep.org Subject: LF: R: hrd i5mxx & ik5zpv Date: Thu, 11 Mar 1999 15:54:49 +0100 MIME-Version: 1.0 Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org -----Messaggio originale----- Da: Rudy Gubiolo Inviato: Wednesday, March 10, 1999 23:22 A: rsgb_lf_group@blacksheep.org Oggetto: LF: hrd i5mxx & ik5zpv around 21.00 local time hrd I5MXX & IK5ZPV with quite good signal om my 7 meter vertical. this is my first hrd on 136 for the moment. tnx Marzio fer info. 73 de Rudy I3VWK Ciao Rudy, sono IK5ZPV, valerio, grazie per la QSL telematica.

This could be > used to say 'the signal is audible and reduce the dot size if you > want to get the QSO over a bit quicker'. I vote for the four dashes in *this* meaning for three reasons: 1. Dashes are much more detectable as dots especially in cases of pulsatile and/or Lux-Effect noise circumstances. If A could hear B very well, B could detect A very bad due to local conditions. 2. It stands for nothing I guess (apart from the old fashioned german "ch"). 3. It would be a good match to the dashed style of TMO. > The main problem is that on being told that the signal is audible > there is a temptation to go for fast CW. It happened to me (twice) > but I wont go for fast CW again in the middle of a SCW QSO. A signal could be audible but nearly unreadable in "fast" Morse. Detecting a carrier is much easier than to understand a "normal speed" code (not only for neurophysiologic reasons...). "Reducing dot length" could mean in steps of 500ms. > There are two reasons: > The bandwidth settings and often the receiver tuning have to be > re-adjusted.

Adding four dashes to our source codes should be very easy.

Maybe a step between 'O' and RST is desirable. I propose to use 'T','M','O','OS' (sent only one time), or '43N'. If you receive 'OS' you should shorten the dot time. Next question: how short? I think that a step of 3 times is OK, so from 3 sec to 1 sec. 73 de IK1ODO Marco Rivalta, ITALY JN35SA (N 45 01' 25.6", E 7 31' 09.4") From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 5313 invoked from network); 11 Mar 1999 18:50:31 -0000 Received: from magnet.plus.net.uk (HELO magnet.force9.net) (195.166.128.26) by medusa.plus.net.uk with SMTP; 11 Mar 1999 18:50:31 -0000 Received: (qmail 17167 invoked from network); 11 Mar 1999 18:53:05 -0000 Received: from post.thorcom.com (194.75.130.70) by magnet.plus.net.uk with SMTP; 11 Mar 1999 18:53:05 -0000 Received: from troy.blacksheep.org ([194.75.183.50] ident=root) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10LAYE-0000LY-01; Thu, 11 Mar 1999 18:51:22 +0000 Received: (from root@localhost) by troy.blacksheep.org (8.6.12/8.6.12) id SAA04983 for rsgb_lf_group-outgoing; Thu, 11 Mar 1999 18:48:05 GMT X-Priority: 3 X-MSMail-Priority: Normal Received: from post.thorcom.com (root@post.unica.co.uk [194.75.183.70]) by troy.blacksheep.org (8.6.12/8.6.12) with ESMTP id SAA04917 for ; Thu, 11 Mar 1999 18:41:36 GMT Received: from nms.rz.uni-kiel.de ([134.245.1.2]) by post.thorcom.com with smtp (Exim 2.04 #3) id 10LARq-0008Kj-00 for rsgb_lf_group@blacksheep.org; Thu, 11 Mar 1999 18:44:46 +0000 Received: from mail.uni-kiel.d400.de (actually srv1.mail.uni-kiel.de) by nms.rz.uni-kiel.de with Local-SMTP (PP); Thu, 11 Mar 1999 19:40:29 +0100 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from nephro.uni-kiel.de by mail.uni-kiel.d400.de (SMI-8.6/SMI-SVR4) id TAA01482; Thu, 11 Mar 1999 19:40:27 +0100 Message-ID: <36E80E2B.B222616F@nephro.uni-kiel.de> Date: Thu, 11 Mar 1999 19:40:43 +0100 From: "Peter W.

Always a lot of questions remain unaswered, it seems that everyone is solving the VLF in his own manner, its similar to things hapen in the EME community from where the TMO reporting system is comming !. With my actual HM equipment and PC the QRS type communication is still far way from me. Have lately seen very incouraging info's regarding VLF antennas built on small surfaces, there was no mention about the ground systems. Was reading in a very old book about VLF antennas and the Braun's grounding praxis. To day have read a message from IK5ZPV describing his impresive ground sys. Do use myself the "ground" ofered by the urban heating network, sure its may be OK but not ideal, the RF curent measured in aerial and in the ground wire are more or less the same. Our backyard is only 12 x 8 m, good soil conductivity, will a small ground system improve the antenna eficiency over the actual "ground" ?. Would like to know, just for comparaison, what's the antenna curent for a VLF tx claimed for 25W output ? (about 75W input, class B). Thanks in advance for informations, 73 & DX, Szigy.

Hello Szigy, the ground offered by a large heating network may be not so good, if tubes are thermally (and electrically) insulated. > Would like to know, just for comparaison, what's the antenna curent for >a VLF tx claimed for 25W output ? (about 75W input, class B). If it was my system, about 0,9A (I have 5,1A with 800W, 31,5 Ohm total R including the variometer and all losses) My earth situation is very lucky, however. I had a pre-existing ground system at this site, measuring about 27 Ohm at 137 kHz. Calculation demonstrate that the ground loss is lower if the antenna has a capacitive top hat. The calculated ERP is better for a short antenna with heavy top load, comaparated with a vertical twice as long, due to inferior losses. Try the programs of G4FGQ and do some simulations. 73 de IK1ODO Marco Rivalta, ITALY JN35SA (N 45 01' 25.6", E 7 31' 09.4") From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 20047 invoked from network); 12 Mar 1999 20:48:40 -0000 Received: from magnet.plus.net.uk (HELO magnet.force9.net) (195.166.128.26) by medusa.plus.net.uk with SMTP; 12 Mar 1999 20:48:40 -0000 Received: (qmail 12618 invoked from network); 12 Mar 1999 20:51:21 -0000 Received: from post.thorcom.com (194.75.130.70) by magnet.plus.net.uk with SMTP; 12 Mar 1999 20:51:21 -0000 Received: from troy.blacksheep.org ([194.75.183.50] ident=root) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10LYtZ-00022w-00; Fri, 12 Mar 1999 20:51:01 +0000 Received: (from root@localhost) by troy.blacksheep.org (8.6.12/8.6.12) id UAA16528 for rsgb_lf_group-outgoing; Fri, 12 Mar 1999 20:47:48 GMT Received: from post.thorcom.com (root@post.unica.co.uk [194.75.183.70]) by troy.blacksheep.org (8.6.12/8.6.12) with ESMTP id UAA16457 for ; Fri, 12 Mar 1999 20:36:41 GMT Received: from mcclure.tinet.ie ([159.134.237.31]) by post.thorcom.com with esmtp (Exim 2.04 #3) id 10LYih-0000kl-00 for rsgb_lf_group@blacksheep.org; Fri, 12 Mar 1999 20:39:47 +0000 Received: from p142.lifford1.tinet.ie ([159.134.235.142] helo=beachwood.tinet.ie) by mcclure.tinet.ie with smtp (Exim 2.05 #23) id 10LYf1-0002Jp-00 for rsgb_lf_group@blacksheep.org; Fri, 12 Mar 1999 20:35:59 +0000 From: "finbar o'connor" To: rsgb_lf_group@blacksheep.org Subject: LF: Re: First EI-PA Date: Fri, 12 Mar 1999 20:38:32 -0000 Message-ID: <01be6cc8$4b8ddd40$8eeb869f@beachwood.tinet.ie> MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 4.71.1712.3 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Sender:
