Hi David and all.

Peter G3LDO has leant me his Decca for a few weeks and

I have re-modified it for 73KHz.This mod. uses additional coils which slide into the existing ones so enabling fine adjustment and are of course easily removable so that the transmitter can be put back to 136 in a few minutes.

On 73KHz I am getting 4A into my aerial (this requires 950W from the Decca),but it runs very cool.

The vert section of my Ant. is 14.5M high and Eznec gives me a Rres. of 0.018 on 73Khz. So at 4A I have 288mW Rad.Pwr. Field strength tests on 136 ( I hav'nt done any on 73 yet) indicate a

3db loss. Assuming the same on 73 we have 144mW. However I am a bit confused here after reading Dicks comments on your

marathon tests,in which he mentions 2.62db gain for a monopole. If this is correct then the loss due to the environment is 5.62db not 3db. For the moment I am staying with 144mW which is a little under half of the power I was radiating earlier in the year on 136.,with reasonably good conditions I recon it should get across.

I hope the frequency is clear ,John did not seem to have any problems when he heard me earlier and Jon also recons its OK.

I will beacon again tonight although things appear very disturbed at the moment.

I will also be at Windsor on the Saturday and possibly the Sunday.

73s Laurie.

Hello Laurie / Group.

Do you have the Decca running on 73 now Laurie? If so, what is the estimated ERP on that band and do we know what frequencies are clear on the East Coast.

Also have ticket for the Sat night at Windsor.

Many thanks to everyone interested in more tests this winter,

Jon W1HJ and John W1TAG have expressed an intrest.

I propose to kick off with a bit of 73KHz beaconing before Alans predicted disturbance occurs so I will run tonight and Saturday night at least. I will announce further tests depending on conditions.

Frequency will be 71,921.5KHz DFCW. shift 0.1Hz up for dashes. Use 60sec dot ARGO. Starting time 2300UTC

for about 6 hours.

This is without any doubt the signal to look for. This signal has a very unique characteristic even when the signal is extremely weak visually, just a sliver wide trace of a line on the display you can see even at this level a "bloom" as the signal goes into an FSK burst of transmission. By a "bloom" I mean a very short broadening of the signal spectrum, it is absolutely unique. Non of the Loran C or Power Company carrier and spurious noise signals from the Power Company signals have this single characteristic. I have been able to see DCF39 all day long, even in July and August this year and positively ID the signal by these tiny randomly spaced "blooms" on the signal line. This signal also has a very impressive frequency stability, I am able to hold the signal in a single DFT line for hours on end. I also observe here that if you see the DFT line move (about 9 out of 10 times), down one DFT line, there will be an announcement of a solar flare from IPS in Australia a short time later. I now have secondary processing ability here to go look at the DFT data I am collecting during receive sessions. For daytime reception of DCF39 I regularly use ARGO at the longest bit setting possible and also I am now using the DSP56K Box I have here. Have you started or have ready a transmitting antenna yet Steve? Good Luck, you will hear this signal over the winter I am sure of that.

Which signals (commercial broadcast) would stand the best chance of >being heard? < Steve, you might want to try to listen to the commercial transmitter DCF39 in Magdeburg on 138.830 kHz (see http://www.qru.de/dcf39-beacon.html for details). That transmitter has about 40 kW ERP, so that a good amateur signal from Europe is between approximately 45 to 50 dB weaker than that station. It has been heard at the East coasts of Canada and the US, and a VK station has been able to detect the carrier by taking a long-term averaging software. DCF39 transmitts a steady carrier on 138.830 kHz, interrupted approximately every 10 seconds by a 200 bd FSK signal with the space frequency on 139.170 kHz. Good luck, best 73 Geri, DK8KW (W1KW) LF-Homepage: http://www.qru.de ... currently not QRV but preparing to be ready to transmit again throughout the winter season with about 200 mW ERP, I am located 120 km West of DCF39 ...

Being 'on the fringe' I'm reluctant to have anyone burn electricity at my behest, but I will make an effort to have a rig driving Argo if anyone declares they're going to be on. It's still somewhat stormy and staticky as a rule, quiet nights an exception, but things should steadily improve in that regard. It's been surprising how good conditions have been (judging by the long-wave broadcasters) over the summer when there's been no racket. Been trying to improve on listening antennas to better the topband vertical and, surprisingly, finding it tough; too foresty for e-probes to work well and thus far - with one promising exception - loops are worse for hearing electrical burps and fizzies. With a bit of effort may be better placed than last year. 73 Steve W3EEE From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 21513 invoked from network); 27 Sep 2001 23:16:21 -0000 Received: from unknown (HELO warrior-inbound.services.quay.plus.net) (212.159.14.227) by excalibur-qfe1-smtp-plusnet.harl.plus.net with SMTP; 27 Sep 2001 23:16:21 -0000 Received: (qmail 3152 invoked from network); 27 Sep 2001 23:16:06 -0000 Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by warrior with SMTP; 27 Sep 2001 23:16:06 -0000 Received: from majordom by post.thorcom.com with local (Exim 3.16 #2) id 15mkIR-0004VK-00 for rsgb_lf_group-outgoing@blacksheep.org; Fri, 28 Sep 2001 00:10:23 +0100 Received: from rhenium.btinternet.com ([194.73.73.93] helo=rhenium) by post.thorcom.com with esmtp (Exim 3.16 #2) id 15mkIQ-0004VF-00 for rsgb_lf_group@blacksheep.org; Fri, 28 Sep 2001 00:10:22 +0100 Received: from [62.7.118.129] (helo=default) by rhenium with smtp (Exim 3.22 #6) id 15mkHj-0002w5-00 for rsgb_lf_group@blacksheep.org; Fri, 28 Sep 2001 00:09:39 +0100 Message-ID: <000101c147a8$fddbc1c0$8176073e@default> From: "Alan Melia" To: "LF-Group" Subject: LF: another big flare possible Date: Fri, 28 Sep 2001 00:05:14 +0100 MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 4.72.3110.5 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group Sender: Hi all, NOAA SEC predict the "fair chance" of an isolated major flare in the next three days. If this occurs in daytime over Europe that could mean up to or over 10dB enhancement to most daytime paths, but only for the period the flare is active. If you have unmetered access you could watch the real-time graph from the NOAA site www.sec.noaa.gov/today.html gives the general solar forecast www.sec.noaa.gov/rt_plots/xray_1m.html this gives the 1 minute updated real-time plot URL ...I think you can arrange it to alarm on the computer speaker as well. Otherwise I suppose you could listen for 80m skywave disappearing in the blackout phase.

I would like to improve on my 73KHz sighting my John and thanks to Peter G3LDO have a Decca TX ready to go !
There is also still much to do on136 including a hand keyed crossing !
I am ready to beacon on 73 or 136 whenever anyone is ready to

I'm ready and willing to look for signals. Last season was so sucessful on 136 I hope it can repeated on 73KHz. Just let me know when the beacons will be on.

Also my new FT-100D is more sensitive on 136 kHz with **IPO** on ( I think that mean preamp off but manual does not specify what they mean with IPO on, on the HF bands IPO on = premp off). May be that a coupling transformer at he output of the preamp does the bad job. I writed an e-mail to the italian YAESU rapreentative, they replied that YAESU need a lot of compliants before to make some improvement. Actally YAESU responce was that 136 kHz is an unused band. Please write to YAESU. I have a 20 dB preamp with band pass filter before the rig.

I have a late mk1 model and it works fb and I use it as a generator source to drive my 73/136 pa. I use it on 7.3/13.6 mhz low power and divide by 100 for the appropriate lf bands. It is very stable on tx and works well also on RX 136 but I have a large antenna. I did say earlier that on a small antenna it is not sensitive enough. I compared it with other rigs like the ts50 for example on a short antenna in the early days and it was not very good. When I put the big antenna up then it was more than adequate with the pre amp on. The ts50 was too sensitive on the big antenna and needed external attenuation. I have other receivers available as mentioned in previous messages and all are very good but it depends a lot on the antenna in use as regards sensitivity. What would suit one persons needs would not suit another. Using the 706 with my present antenna, the rf gain has to be backed off slightly to obtain max signal over noise but has more than adequate sensitivity. The antenna will determine what rx suits your needs best. 73 de Mal/G3KEV/SCARBOROUGH From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 20407 invoked from network); 26 Sep 2001 18:27:44 -0000 Received: from unknown (HELO murphys-inbound.services.quay.plus.net) (212.159.14.225) by excalibur.plus.net with SMTP; 26 Sep 2001 18:27:44 -0000 X-Priority: 3 Received: (qmail 17289 invoked from network); 26 Sep 2001 18:27:24 -0000 X-MSMail-Priority: Normal Received: from unknown (HELO post.thorcom.com) (212.172.148.70) by murphys with SMTP; 26 Sep 2001 18:27:24 -0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from majordom by post.thorcom.com with local (Exim 3.16 #2) id 15mJIV-0004oi-00 for rsgb_lf_group-outgoing@blacksheep.org; Wed, 26 Sep 2001 19:20:39 +0100 Received: from mailhost.netscapeonline.co.uk ([194.201.52.152]) by post.thorcom.com with esmtp (Exim 3.16 #2) id 15mJIU-0004od-00 for rsgb_lf_group@blacksheep.org; Wed, 26 Sep 2001 19:20:38 +0100 Received: from ldsas10-74-125-223.cw-visp.com ([212.137.125.223] helo=netscapeonline.co.uk) by mailhost.netscapeonline.co.uk with esmtp (Exim 3.02 #1) id 15mJ9C-0005ZI-00 for rsgb_lf_group@blacksheep.org; Wed, 26 Sep 2001 18:11:03 +0000 Message-ID: <3BB20E4E.9CA8230A@netscapeonline.co.uk> Date: Wed, 26 Sep 2001 18:20:14 +0100 From: "gii3kev" Organization: Netscape Online member X-Mailer: Mozilla 4.6 [en-gb]C-CCK-MCD NetscapeOnline.co.uk (Win95; I) X-Accept-Language: en-GB,en MIME-Version: 1.0 To: "rsgb rsgb" Subject: LF: deaf!!

I can now confirm that some Russian ALPHA transmitters are back on air (someone must have paid the electricity bill - guess why ? )
A signal can be clearly seen and heard (with the software-VLF-radio) on 11.905 kHz as short pulses (blip-blip-blip..).

A list of VLF frequencies can be found at
http://www.vlf.it/itulist/itulist.htm.

Good luck hunting !

To All from PA0SE

Jim, M0BMU, deserves great praise for his fine job of measuring field strength at a large number of locations and I certainly would like to receive the graphs he made. Thanks Jim in advance.

I could not resist the temptation to model Jim's aerial using K6STI's computer program AO.

This yielded a radiation resistance of 0.017 ohms. At an aerial current of 2A radiated power becomes 0.017 * 2 * 2 = 68mW. This is EMRP, Effective Monopole Radiated Power. A short vertical monopole has a gain of 1.829 (2.62dB) over a half wave dipole in free space. As ERP is related to such a dipole calculated ERP at M0BMU is 1.829 * 68 = 124mW. Jim mentions 150mW ERP but he also says the aerial is slightly over 8m average height. I used 8m for the simulation and this may explain the difference between 124W and 150mW.

AO also permits to compute what is called the "near field" but in reality is the total field (near field plus far field) up to a distance of 2km. I did this for Jim's aerial in steps of 200m. Both the electric component E of the field in V/m and the magnetic component A in A/m are computed.

In the far field E/H = 120 * pi = 377 ohms.

In the following table E/H is shown for Jim's aerial and for my own one.

At M0BMU At PA0SE

Distance (m) E/H (ohms) Distance (m) E/H (ohms)

200 493 200 536

400 256 400 262

600 286 600 288

800 317 800 318

1000 336 1000 336

1200 347 1200 348

1400 354 1400 356

1600 359 1600 361

1800 364 1800 364

2000 366 2000 365

Very near the aerial the magnitude of E/H depends also on the configuration of the aerial, as shown in the table for the aerials of M0BMU and PA0SE. But the difference is already negligible at 400m distance. (My aerial is a T with the top of the vertical leg at 18m height).

The tables show that even at 2km E/H is different from 377 ohms, which means the influence of the near field has not yet disappeared.

In the far field both E and H decrease in a linear way with distance (at least in the region where field strength measurements are being made, say up to 10 km from the transmitter).

So going from 1km to 2km both E and H should decrease by a factor of 2.

The computer shows that at M0BMU that factor is 1.92 for E and 2.09 for H. This also shows some contribution of the near field to the total field. But for FS measurements the discrepancy is probably small enough to be neglected; also taking into account that other factors can cause variations in FS of several decibels.

In dry weather aerial current at PA0SE is 1.95A. Radiation resistance is calculated at 0.043 ohms. So radiated power is 1.95 * 1.95 * 0.043 = 164mW EMRP = 300mW ERP.

At 5.83km distance, well into the far field zone, field strength showed ERP to be 95mW.

A difference of 5dB.

But the measurement was made at one location only, though selected carefully for the absence of disturbing metal objects. One never knows what is below the surface of course but the FS did not fluctuate when moving around a bit so it seemed a good location.

But Jim has shown us that for serious work a single measurement is certainly not good enough.

Onderwerp: LF: <TECH> Results of antenna tests

Dear LF group,

I have now made a total of 155 field strength measurements on 135.923kHz, all using the same antenna with 2A antenna current. I suspect this is the most detailed FS measurements yet done on an amateur 136k antenna, and some of the results are quite interesting.

The antenna is an inverted L, with slightly over 8m average height, and a single top wire 40m long running east (the feed end) to west. The antenna current was measured at the bottom of the downlead, where it joins the loading coil. I made measurements at distances between 148m and 8.1km, with a wide range of different directions between TX and RX. The equipment used was my homebrew, car- mounted, ferrite rod antenna and preamp, with an SPM-3 selective level meter. This combination was calibrated using a Helmholz coil arrangement. Distance and bearing between TX and RX was measured using a GPS receiver.

I worked out the ERP in dBW for each measurement, and plotted these results against the distances and bearings at which the measurements were taken, using a spreadsheet. The graph of ERP vs. distance shows that at ranges below about 600m, the calculated ERP increases rapidly, suggesting this distance is the minimum that could be considered "far field". There are also several points where the ERP was 10- 15dB higher than average; plotting ERP against bearing revealed that these occur in a sharp peak around a bearing of 270 degrees, up to a distance of 1km or so. It turned out that all these points were measured on Bulls Lane, a road going due west from my QTH. Closer inspection showed that there are overhead phone lines on poles along this road, one of which connects to my QTH. The overhead lines run parallel to my antenna within 10m in places, so I expect the unusually high FSs were due to signals being coupled into, and propagating along, the phone wires. The wires go into buried cables after about 1.2km, and the field strength returns to normal.

The area in which I live is a mixture of urban and countryside; in urban areas there are many buildings, while in the rural areas there are overhead phone or power lines by the sides of most roads. This makes "ideal" locations for field strength measurements hard to find, so most measurements were made at less than perfect locations. In spite of this, the ERP figures for most points are within 2 or 3dB of the average, showing quite consistent measurements can be made under these conditions. I tried returning to the same location on subsequent days; the measurements were within a 1dB range. Also G3NYK supplied some plots of the test signal received at his QTH; these remained stable within 1dB or so as well. So one can be reasonably confident that the observed variations are due to the location, and not drift in TX output or RX sensitivity.

I looked at potential causes of changing ERP results - apart from the phone lines and short distances, I found that in at least one case, measuring on top of a motorway bridge enhanced the signal level by a few dB. Once I had excluded these deviant measurement points, the average ERP was -11.2dBW, equivalent to a (geometric) mean of 75mW, compared to a calculated value of 150mW. There was little evidence of directional behaviour of the antenna, although there is perhaps a slight "bump" of 1 or 2 dB around 120degrees bearing. Interestingly. this is roughly the direction the aerial masts at Brookmans Park transmitting station are in, so they might be having a slight parasitic effect. However, there are only a few points in this direction, and they were all taken on one road, the Ridgeway, which as one would expect is elevated above the surrounding ground.

The conclusions so far - it is possible to make reasonably consistent field strength measurements on amateur LF antennas, provided sufficiently detailed measurements are available to identify disturbing factors, which can cause errors of 10dB or more. In the mixed urban and rural environment in which these measurements were done, one can expect variation of about +/- 3dB between measurements - repeating a measurement at the same location gives results within 1dB. The "far field", where field strength is inversely proportional to distance, starts at about 600m distance in the case of this antenna. At shorter distances, the field strength decreases more rapidly with distance. The measured ERP is 3dB down on the calculated value in this case, roughly in line with previous measurements. As would be expected, there is little or no directional behaviour in a 40m long, 8m high inverted L at 136kHz.

If anyone would like to play around with the figures I have so far, I have all the data in an Excel spreadsheet, which I could e-mail to them. I originally tried to post a couple of the graphs to the reflector, but it was having none of it, so if anyone would like to see the results let me know, and I'll send them individually.

I plan to do similar tests using different antennas, and also on 73kHz, in the near future.

Cheers, Jim Moritz

I will not attend the Convention. The UK is becoming a bit too expensive for a retired Dutchman.

Will there be a station on 136kHz?

Hello Rik.

Thank you for that URL.

I did run a search on the web site but could not find a result to match the model number of the analyser that I have bought.

If all else fails, I will call the company and try to find a supportive engineer!

Hope to talk to you over the weekend of the HF Convention at Windsor.
G3GRO and the Crawley club have received permission to operate a LF 'repeater' on either 28 / 50 / or 144MHz. With 135 - 138 relayed from a quiet location we should be able to hear a few stations this year.

The rate of recombination of the E (?) layer causing the height to change at dusk / dawn will move at this sort of rate.

I did see Doppler shifts, although not perhaps quite as great as this, on the signals from Larry at least once. This is one of the mechanisms limiting the data rates we can go down to when using very low signalling rates.

A couple of years ago I made some tests receiving DCF, the German time signal, comparing its phase against a locally generated Caesium reference. The interference patterns at dusk / dawn showed fading consistent with interference between the two skywave & groundwave signals, one of which was changing at a rate consistent with this order of magnitude of velocity.

Subject: LF: Doppler effect.

Dear all.

I have the Argo screen-shots of ZL6QH recorded in Papua New Guinea, a path of about 4,700km. This is not very different from out trans-Atlantic tests but Ricks traces show a Doppler effect around midnight which spreads the signal over about 0.1Hz, I have never seen this on a 136k trans-Atlantic trace.

Have a look at the shots on http://www.wireless.org.uk/newspic63.htm and see what you think.

Rick has calculated that the reflecting medium would have to have a velocity of around 100m/sec, assuming a double hop, to cause this kind of shift.

Any propagation brains care to speculate on the cause of this, and is there a reason why we haven't seen it on 136?

73.

Dave.

Hi all,

My announcement omitted the call sign of Kevin ZL4MD as a participant in the TransPac tests. The following is a corrected first sentence. Would anyone publishing the material please add the call sign.

On Saturday 22 September ZL6QH, ZL3PN, ZL3JE, ZL4OL, ZL4MD and AX2TAR (VK7ZAL) transmitted test signals in the 165 - 190 kHz band, for so-called trans-Pacific tests.

Thanks,

Bob ZL2CA

Hi all,

Following is the text of an announcement to the amateur radio media. I will email the Argo file to personal addresses, on request.

73, Bob ZL2CA

A SECOND CLAIM OF ZL TO VE AMATEUR LF DX 26 September 2001

On Saturday 22 September ZL6QH, ZL3PN, ZL3JE, ZL4OL and AX2TAR (VK7ZAL) transmitted test signals in the 165 - 190 kHz band, for so-called trans-Pacific tests. Various DX listeners had prior knowledge of the schedule of individual test frequency and coding used by each station.

As occurred in the 30 June trans-Pacific tests, Steve VE7SL managed to receive signals from ZL6QH before VE7 dawn. This time VE7SL obtained an Argo capture of both frequencies of the DFCW transmission. The path length is estimated to be 11,709 km.

Refer to the associated Argo graphic. The ZL6QH signal is in the lower half of the screen. The transmitted signal used dual frequency keying, with 0.4 Hz frequency shift. The uniquely coded transmission consisted of repetitive sending of QQQQQ… sent as 184.4001, 184.4001, 184.3997, 184.4001 kHz and then a gap, with all elements being of 120 seconds (2 minutes) duration. This means sending a single Q took ten minutes.

The Argo graphic of the VE7SL reception shows inverted audio FSK , but otherwise agrees with the dot length, sequence and frequency shift of the ZL6QH transmission. The explanation for the inversion is that the Icom IC-R75 receiver used by VE7SL happens to give inverted FSK in the audio output when used in the normal CW mode. VE7SL used an RF signal generator to subsequently verify that an Argo trace (showing receiver audio output) went lower in frequency when the RF frequency went higher. Note that the parallel vertical red lines in the centre of the Argo graphic are a software option for selecting either short or long "ticks" and once selected, a tick stays on the screen. The left side of the long tick is close to 40 minutes before the 1401 UTC sunrise at VE7SL. The signal faded rapidly about 3 minutes after sunrise. It was still dark in New Zealand at VE7 sunrise.

The ZL6QH LF signal was generated using a modified TS-850SAT, in SSB mode, fed with audio from a lap top PC, using soundcard software developed by Steve VK2ZTO. TS-850 frequency control was by means of a high performance TCXO master oscillator. The low level LF signal from the TS-850 transverter port was fed to an external LF power amplifier, and the output power was around 500 watts. The radiated power is estimated to be 5 watts. The antenna was a long wire at the Quartz Hill club station, which is run by the Wellington Amateur Radio Club. The ZL6QH operators were Andrew ZL2BBJ and Bob ZL2CA.

ZL6QH is seeking permission to transmit in the 136 kHz band, which could widen the scope of testing beyond "trans-Pacific", and give European listeners a better chance at receiving amateur LF DX from down-under.

I just received the Info from a VLF experimenter (not a radio amateur) that the ALPHA system seems to be back on. He observed signals on 11.905kHz and 12.649kHz. I have not verified this yet (because my neighbours dimmers and TV still running) but I will as soon as possible.

Other topic:
Another coronal mass eruption is on its way, it will hit the earth later this night (Sat 25). No Aurora signals audible on 144 MHz from SK4MPI yet (at 20:00 UTC), but very good signals can be expected later (if you are also active on this band). The Northern Lights may be so strong that -with a little luck- they can be seen even in the mediterranean area.
Maybe also interesting to monitor LF beacons tonight, as Alan told earlier. Think I'll get up at 02:00 UTC in the morning to see what's going on on LF and VHF.

Good night,
Wolf DL4YHF.

Dear all.

I have the Argo screen-shots of ZL6QH recorded in Papua New Guinea, a path of about 4,700km. This is not very different from out trans-Atlantic tests but Ricks traces show a Doppler effect around midnight which spreads the signal over about 0.1Hz, I have never seen this on a 136k trans-Atlantic trace.

Have a look at the shots on http://www.wireless.org.uk/newspic63.htm and see what you think.

Rick has calculated that the reflecting medium would have to have a velocity of around 100m/sec, assuming a double hop, to cause this kind of shift.

Any propagation brains care to speculate on the cause of this, and is there a reason why we haven't seen it on 136?

73.

Dave.

I have now made a total of 155 field strength measurements on 135.923kHz, all using the same antenna with 2A antenna current. I suspect this is the most detailed FS measurements yet done on an amateur 136k antenna, and some of the results are quite interesting.

The antenna is an inverted L, with slightly over 8m average height, and a single top wire 40m long running east (the feed end) to west. The antenna current was measured at the bottom of the downlead, where it joins the loading coil. I made measurements at distances between 148m and 8.1km, with a wide range of different directions between TX and RX. The equipment used was my homebrew, car- mounted, ferrite rod antenna and preamp, with an SPM-3 selective level meter. This combination was calibrated using a Helmholz coil arrangement. Distance and bearing between TX and RX was measured using a GPS receiver.

I worked out the ERP in dBW for each measurement, an d plotted these results against the distances and bearings at which the measurements were taken, using a spreadsheet. The graph of ERP vs. distance shows that at ranges below about 600m, the calculated ERP increases rapidly, suggesting this distance is the minimum that could be considered "far field". There are also several points where the ERP was 10- 15dB higher than average; plotting ERP against bearing revealed that these occur in a sharp peak around a bearing of 270 degrees, up to a distance of 1km or so. It turned out that all these points were measured on Bulls Lane, a road going due west from my QTH. Closer inspection showed that there are overhead phone lines on poles along this road, one of which connects to my QTH. The overhead lines run parallel to my antenna within 10m in places, so I expect the unusually high FSs were due to signals being coupled into, and propagating along, the phone wires. The wires go into buried cables after ab out 1.2km, and the field strength returns to normal.

The area in which I live is a mixture of urban and countryside; in urban areas there are many buildings, while in the rural areas there are overhead phone or power lines by the sides of most roads. This makes "ideal" locations for field strength measurements hard to find, so most measurements were made at less than perfect locations. In spite of this, the ERP figures for most points are within 2 or 3dB of the average, showing quite consistent measurements can be made under these conditions. I tried returning to the same location on subsequent days; the measurements were within a 1dB range. Also G3NYK supplied some plots of the test signal received at his QTH; these remained stable within 1dB or so as well. So one can be reasonably confident that the observed variations are due to the location, and not drift in TX output or RX sensitivity.

I looked at potential causes of changing E RP results - apart from the phone lines and short distances, I found that in at least one case, measuring on top of a motorway bridge enhanced the signal level by a few dB. Once I had excluded these deviant measurement points, the average ERP was -11.2dBW, equivalent to a (geometric) mean of 75mW, compared to a calculated value of 150mW. There was little evidence of directional behaviour of the antenna, although there is perhaps a slight "bump" of 1 or 2 dB around 120degrees bearing. Interestingly. this is roughly the direction the aerial masts at Brookmans Park transmitting station are in, so they might be having a slight parasitic effect. However, there are only a few points in this direction, and they were all taken on one road, the Ridgeway, which as one would expect is elevated above the surrounding ground.

The conclusions so far - it is possible to make reasonably consistent field strength measurements on amateur LF antennas, provid ed sufficiently detailed measurements are available to identify disturbing factors, which can cause errors of 10dB or more. In the mixed urban and rural environment in which these measurements were done, one can expect variation of about +/- 3dB between measurements - repeating a measurement at the same location gives results within 1dB. The "far field", where field strength is inversely proportional to distance, starts at about 600m distance in the case of this antenna. At shorter distances, the field strength decreases more rapidly with distance. The measured ERP is 3dB down on the calculated value in this case, roughly in line with previous measurements. As would be expected, there is little or no directional behaviour in a 40m long, 8m high inverted L at 136kHz.

If anyone would like to play around with the figures I have so far, I have all the data in an Excel spreadsheet, which I could e-mail to them. I originally tried to post a coupl e of the graphs to the reflector, but it was having none of it, so if anyone would like to see the results let me know, and I'll send them individually.

I plan to do similar tests using different antennas, and also on 73kHz, in the near future.

Cheers, Jim Moritz

The DDS filter is a customised Chebyshev design passing just the wanted band and, together with the DDS overclocking, means there are no spurious products at frequencies that could cause problems with the frequency upconversion plan. The image in the MF broadcast band (910 - 1060kHz) my main real design problem, and that was overcome with a high order LPF on the input giving over 100dB rejection in this region. When used with a resonant antenna for LF, this rejection level proved sufficient to make image signals inaudible. I can bring this Rx along to the HF Convention. One use for a DDS I intend to look at shortly, is using the image response for multiplying up to microwaves. By clocking an AD9851 at 150MHz, and set for 42MHz output, but instead of the normal Low Pass FIlter, use a bandpass filter at the first image response of Fclock - Fout, ie 108MHz in this case. Then by multiplying by 96 in a conventional multiplier stage that will give a signal at 10368MHz, with a very low phase noise determined only by that of the clock oscillator multiplied up. A good quality VHF Butler oscillator as used on uWaves is more than adequate for that.

I now have the data from Brian's (CT1DRP) plot of DCF39 ( a path length of 1987 kms) for that period. This shows that there was about a 15dB peak enhancement to the average conditions at that time of day on the path from DCF39 to Porto. This would not be so evident where the ground wave signals are stronger than those produced by the ionospheric 'reflection', but it should have been evident at path distances in excess of about 700kms, for amateur signal strengths. The interesting thing is that the enhancement, over average daytime levels for the last two weeks, exceeded 10dB over a period of about 60 minutes, in other words a very usable 'lift' for inter EU contacts There are forecasts of the possibility of more flares in the M and X class from the same region, so if there are any OH, OM, S52, HA stations around It could pay to keep an eye on the NOAA site. This will give a real-time display of the the GOES satellite X-ray detectors, any levels over M1.0 can give useful enhancements. This is a daylight only effect and the enhancements seem best between about 09000z and about 1600z at this time of year. Thanks to Brian for a great bit of continuous data logging.

Alan Melia sent me a message today asking wether anyone

intended any T/A activity this year. We are already past the time

when last year the first crossings were made.

I would like to improve on my 73KHz sighting my John and thanks to Peter G3LDO have a Decca TX ready to go !

There is also still much to do on136 including a hand keyed crossing !

I am ready to beacon on 73 or 136 whenever anyone is ready to

DDS LOs are extremally quiet - there is no added phase noise due to the synthesizer process and the phase noise you do get is that of the clock divided by the frequency synthesis ratio. There can be spurious frequency products at well defined levels, but they can usually be dealt with by filtering and proper frequency planning.

I agree that it's worth putting on. So far the agenda for this session includes: a) G4JNT outlining his QRO TX b) Crawley Club report on MB7LF - G3YSX to arrange c) 2 papers from "Crawley Round Table" - G3YSX to arrange I will enquire whether we can use the 2pm slot, though that may upset the plans to keep it clear for Martti's keynote presentation. Short of that we could run the session at 1800 on Saturday. Watch this space.... ---- As a separate issue I am preparing the agenda for the LF Forum. So far it looks like: a) Presentation of RSGB LF Experimenter's Award, The Nevada Cup for 2001 b) Presentation of DARC, AMRAD, RSGB Transatlantic Challenge Awards and Certificates c) 136kHz - report on RSGB and IARU Region 1 activities(G3WKL) d) 500kHz - report on RSGB proposal(G3WKL) Grateful for suggestions for additions to this list 73 John Gould G3WKL -----Original Message----- From: majordom@post.thorcom.com [mailto:majordom@post.thorcom.com]On Behalf Of G0MRF@aol.com Sent: Monday, September 10, 2001 17:48 To: rsgb_lf_group@blacksheep.org Subject: Re: LF: Re: October IOTA/HF Conference ?

My results sound similar to yours....I reckoned it would need between 20 and 40 dB of pre-amp at 136 to give the 100nV sensitivity I get on the AOR 7030. I did not bother with 73k at the time. If you have a very big aerial like Mal's I suppose you get such a lot of signal (and noise!) that you couldn't use much more gain. For us lesser mortals it is barely adequate. I was also quite taken aback by the "chunder" that could be heard with no signal at 136k, this is probably the PLL reference. It is something I do not hear on the 7030 (even at the 10nV level) despite DDS LOs not being famed for their quietness. Stick with it, we look forward to hearing another station from your region (particularly on 73!!) Finbar is keeping the flag flying on 136k at the moment. He is consistantly heard here on the East Coast (Nr Woodbridge, Suffolk) at about 579 these days, and is now working into Germany.

I made an unexpected purchase at the Leicester rally last weekend.
I wonder if anyone has any idea where I could find either an operators or service manual for an Anritsu MS62B Specrum Analyser?

It works OK, but I would like to try and build a tracking generator for it and need to know a little about the signals it provides on the back panel.

Thanks

Wolf seems to be unlucky with his IC-706. I have a Mk1 which is a little deaf on 136kHz, but adding a one-transistor pre-amp makes it a very good receiver. I experience no interface noise when using the outside antenna, though a few years ago when I did a lot of 73kHz portable work, I noticed that the front panel display radiated LF for a few centimetres. The synthesiser on the 706 is excellent and during last winter's transatlantic tests it stayed within 0.1Hz for hours at a time, and once it was calibrated with Argo and BBC 198kHz it could be re-set reliably day after day.
