I have seen some books abt Power Lines Carrier of the power companies in ex USSR. I also had conversation with the specialists in this area of communication. I can inform some details... 1.Range of used frequencies 36... 620 kHz. 2.The two-channel duplex system(number of channels - 12 with 4kHz wide), for example 36-84 kHz(bottom) and 92-143 kHz(top) pairs of frequencies is used. It is interesting, that at such variant the control frequencies 96 or 136 kHz(!!) are used. The narrow-band electromechanical filters are applied for this purpose (for controls frequencies). 3.On channels the telephone conversations and (or) telecontrol can be transferred. 4.Modulation - SSB or FM. Output power 20...100w. 5.Possible distances - up to 100km. 6.The specialists speak, that they have no QRM from Russian Loran, RSDN or LF/MF broadcasting stations on such channels of communication !(?) They do not know what this such (can be they the bad specialists? ;-) But they confirm that this communication via Power Lines "dies" in Russia and other exUSSR - the equipment is not made any more. 7.The basic QRM of such communication - electrical handicapes in high-voltage wires ("Crown"), damaged isolators, crude weather and thunder-storms. But the communication via Power Lines sometimes creates QRM to other telecommunications! 8.I listened to frequencies of the nearest power companies, but accepted very poorly (on headphones). My questions: - About such communication and QRM from HAMs speaks FCC? - The similar communication in USA, Canada and Europe is used? 73!

Still its going to be very interesting (when/if) how much current flows in the tower....the tower and vertical 8mm2 are separated by 5 metres at the moment. Id like it to be further but the forest precludes this. The ground is clay/sand and is the result of alluvial deposits from the last ice age. Mike W2AG (thanks Mike) has pointed out that my part 5 137Khz pending application has been assigned "WD2XDW" - but this doesnt indicate any form of approval and is a normal part of the process. Ill do some tests when I get to see what and if I actually do get some changes with the ends/middle of the top cap when opened/shorted.. I completely agree with your max new ground covering thoughts - as you can see (or not see) from the web site photos Im covering a fair bit and will extend another wire back behind the tower too. Im getting close to having a very small coil.... Its moose calvung season so Im playing canny out there at the moment.

Have put out a couple of tests and one CQ on 137.7 just in case anyone was watching. Haven't finished all the tests yet but so far results are encouraging -except for "The Mystery", which appears to be still there. In short; coil was 'relieved' of as much redundant ply as possible, grew a lot more taps and has now got luxurious quarters of its own clad with uPVC soffit. Feed now by 5sq mm flat twin ('oxygen free' as sold to gullible motorists at vast expense if paid for - mine wasn't,) giving a feeder with a total C of about 35pF. Interestingly enough the antenna current on 73KHz now pins the needle hard against the stop so there has been a further useful increase there. Revision of the meter multipliers necessary! On 137 not so noticeable but some definite improvement. Will be around this weekend but start gallivanting at the end of next week and will be 'LF-less' until 24 June, in time for final obsequies and the obligatory wake on 73.

However there are one or two points that I should like to make which may prove helpfull. I agree that shorting the ends will not make any difference to the performance of the ant. but it might reduce possible corona ! I also agree that the vert wire should be a single wire but it ought to be as vertical as possible to keep its capacity to earth at a minimum. I notice that the tower is quite close(although you have moved the vert wire further away ) I think that the tower should be grounded to the very effectively to the bottom of the loading coil ie any capacitive current should be returned through a low loss connection to the Tx. If this is done there will be no losses associated with the tower(or not too many ). Finally I don't know much about your ground there but my experience is that on poor ground like mine you should get as much wire in the air as possible " This wire does'nt need to be in a straight line mine zig zags between trees but I always try to cover "new" ground and recently discovered that it should be clear ground ie no bushes etc. Hope this all helps and look foreward to seeing a signal from KL. 73 Laurie.

Analysis of Solar Active Regions and Activity from 28/2100Z to 29/2100Z: Solar activity was at high levels. Region 365 (S07W45) once again produced a major flare early in the period. An X1.1/2b event occurred at 29/0105Z that had an associated Tenflare, Type IV and Type II (estimated shock velocity of 1170 km/s.) radio sweeps. SOHO/LASCO imagery depicts a very symmetric full halo CME resulting from the event. This region remains extremely complex (a beta-gamma-delta structure) although the penumbral coverage has shown little growth during the period. Region 368 (S32W15) also managed to produce two notable flares today, an M2.7/1n event at 29/1937Z and an M1.5/1f event at 29/0217Z. This region did show some magnetic growth during the period. No new regions were numbered today. IB. Solar Activity Forecast: Solar activity is expected to be at moderate to high levels. Region 365 continues to show the potential to produce major flare activity. IIA. Geophysical Activity Summary 28/2100Z to 29/2100Z: The geomagnetic field was at unsettled to severe storm levels. A recurrent coronal hole was responsible for the initial elevated conditions. At approximately 29/1155Z the first of two transients associated with the first two X-class flares from late on the 27th and early on the 28th passed the NASA/ACE space craft. The second occurred at approximately 29/1830Z and was responsible for the severe storm conditions seen late in the period. The greater than 10 MeV proton fluxes at geosynchronous orbit achieved event levels at 28/2335Z and reached a maximum of 121 pfu at 29/1530Z. The greater than 2 MeV electron fluxes at geosynchronous orbit reached high levels today. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at predominantly active to major storm levels with severe storm condition anticipated. Another transient passage is expected between 30/0600 and 1200Z on day one of the period. The greater than 10 MeV proton fluxes should remain above threshold levels through day one of the interval.

Subject: LF: Rugby GBR

I have been made aware of the possibility of visiting the BT facility at the recently QRT GBR Rugby transmitter.
Two colleagues had a tour of the site a couple of days ago and were kind enough to pass on the contact name of the organiser.

Should it be possible (and it is only a possibility at this time) for me to organise a similar visit, would anyone on the reflector be interested in coming along?

The site and equipment is slowly being dismantled, so this is probably a one off opportunity. However, personally I can't resist the temptation of seeing a loading coil the size of a house!

Replies direct please.

Your results mirror mine for daytime flare activity. As the "active ingredient" is EM radiation the effect is only felt in the daylight hemisphere. We were in darkness over the T/A path to CFH so nothing shows on that. Last night the path to CFH opened a lot later for just about 2 hours, but levels were better. I expect that propagation conditions will be knocked back in about 3 days time when the CME from that flare arrives. Depending on the direction of its magnetic field it could be good for a major storm (Kp= 7 or higher). If so that will really depress conditions again for some time.

despite overwhelming statics, last night's spectrogram turned out quite interesting: CFH reasonably strong with significant multipath fading, and what must be Brian's slow DFCW on an unusual QRG 137209.7Hz. Luxembourg IM features a remarkable horizontal banding structure, corresponding to the frequencies of common musical notes. Also note the similarity of fading patterns on three of the blue lines, probably emanating from a common antenna in the Frankfurt area, but different from DCF49's 136547.5 spurious.

I have done some crude experiments and have found little difference. However, I have found that the more you join together, the less there is to fall down if a single support rope fails. My three top wires are each supported by their own insulators and polyprop rope, but are shorted at the ends. If any two ropes break, the third will still support the antenna via the shorting wires (the top section will be bent but will work, at slightly reduced efficiency).

As amateur top loaded antennas are generally a lot smaller than the commercial ones (There are some exceptions!) they don't need these considerations. A large two wire flat top for example, typically has stabilising halyards from each end of the spacers down to a comon anchor point at both ends of the flat top and in the middle-. The ones in the middle do double duty as the vertical element as well but will usually be commoned some distance above the top of the loading coil structure so a single wire forms the lower portion of the vertical element. Conversely, the end halyards are usually tied down to an anchor point on the support masts individually, so they can be adjusted individually as required.

  In looking at my LF Inverted L, and specifically the 3 wire top loading
wires - I've a couple of questions...

1. I see a recommendation that the vertical part of the Inv L aerial
wire(s) should be a single wire (ZL recommendation), or if not then three
or how many wires should converge to a single point at the bottom. Why is a
single wire recommended over  a multiple? Em thinking losses into nearby
objects? Wouldn't a multiple vertical wire feed increase  "good non lossy"
C and increase Ra?

The antenna current returns to ground via the capacitance to ground of the vertical and of the top load .
Because we want the current in the vertical part to stay as large as possible over its whole length it is best when  as little current as possible flows from the vertical part to ground. So the capacitance of the vertical part should  be small as compared to the capacitance of the top load.Therefore a single wire is to be preferred.

2. Ive seen a large amount of schematics both for commercial and ham top
loading.of T and L's ...Say for a three wire top loading spaced 1m apart -
should the wires at the far/near end all be shorted together or left open?
Does this affect the total cap either way, or is it just for electrical
"circuit" stability?? Does it make any difference if they are shorted at
any point along the top?? Is there a recommendation which proves open
versus short is better ?

Because the voltage on parallel wires of the top load is the same at neighboring positions a connection between those points will carry no current and therefore has no use. 

Im trying to rationalize that the end of the loading wires are at Zero
Current (no different circulating/local currents between the wires?).. and
it may not be an impedance thing but may help reduce high voltages as the
surface area at the end is now a lot larger...and may reduce corona.

The corona argument is certainly valid.

I have a load of elm sapling at the end of my garden that suffer similarly. I think it is worth putting the reply on the reflector as it may trigger some violent disagreements (I hope ?) or some other ideas, and findings from different sites. Vertical leads for the L. I think the reason for the suggestion of a single wire it to reduce the capacity of the vertical to ground and to surrounding "environment" (probably more improtant for amateur aerials). Nevertheless several amateurs use multiple wire verticals with satisfactory results. Brian had 4 wires originally as an open wire feeder to his 80m cage top. Mal uses three inverted Ls in parallel I believe with the verticals connected at the feed point. Finbar ran four lengths of vertical insulated wires together, through a ring attached to his halyard, and then he fanned them out to form his capacity load. It is advantageous to keep the vertical as far from grounded items like trees, masts, and buildings. Even a couple of metres will make a difference. There are ways of feeding a wire attached to a grounded tower (see Rik Stobbe's tutorial on LF aerials 10 or 11, I think) www.qsl.net/on7yd Top-load wires These need to be separated by at least 70cms to give increased capacitive loading, a metre is probably better, more doesn't gain anything....put another wire in !! The NEC "simulators" will tell you that increasing the top load beyond a length equal to about the height of the antenna will not gain you anything more. It is true that the extra length will not increase the effective height or the radiation resistance (you will probably not find received signals any stronger ) but the increase in capacity is accompanied by an similar decrease in ground loss. Provided they are not strung over lossy bushes, as Laurie has just discovered. I have used 1inch diam plastic water pipe a spreaders its light and seems strong enough. Connection or top load Mike G3XDV discussed this with the group some while back and it does not seem to matter whether the top-wires are in parallel or are zig-zagged backwards and forwards The effect is the same. (I have some in parallel and some "folded back") If you are going to run significant power, then you will need to watch out for areas where there are sharp bends, and also at the ends of the wire. Jim has made some successful corona rings for the ends of his wire. I think they are 3in diameter rings of thick copper wire, supported on the insulators and soldered to the end of the aerial wire. Ralph has done similarly with his SMG beacon (166.3kHz), and has quite a few pics on his web site.. I hope that helps a bit, but you will probably get plenty more ideas to distil into a "program".

Spruce trees are dying/have died in large numbers in S central alaska. Beetle carrying virus. In looking at my LF Inverted L, and specifically the 3 wire top loading wires - I've a couple of questions... 1. I see a recommendation that the vertical part of the Inv L aerial wire(s) should be a single wire (ZL recommendation), or if not then three or how many wires should converge to a single point at the bottom. Why is a single wire recommended over a multiple? Em thinking losses into nearby objects? Wouldn't a multiple vertical wire feed increase "good non lossy" C and increase Ra? 2. Ive seen a large amount of schematics both for commercial and ham top loading.of T and L's ...Say for a three wire top loading spaced 1m apart - should the wires at the far/near end all be shorted together or left open? Does this affect the total cap either way, or is it just for electrical "circuit" stability?? Does it make any difference if they are shorted at any point along the top?? Is there a recommendation which proves open versus short is better ? Mine are open all the way and Im using a converging 3 wire vertical wire feed... I see shorted at the ends, shorted half way, open ended solutions from my peers here... Im trying to rationalize that the end of the loading wires are at Zero Current (no different circulating/local currents between the wires?).. and it may not be an impedance thing but may help reduce high voltages as the surface area at the end is now a lot larger...and may reduce corona. Most commercial T's for NDB short out at the far ends..and I do see single and multiple wire converging vertical wires, so I guess they are all right But a lot of the drawings ref materials show them open!

My favorite on Argo is the "circle" where a seemingly phase stable signal from Loran decides to split into 2, some millihertz apart low and high of the mean freq, and produces a near perfect circle as it migrates away and then recombines into a single freq again over a minute or so. The other are "blobs" - As Ive raised the aerial upto over 100ft the man made stuff is reducing and Im seeing more real radio (perhaps!)...I wonder how much of the blobs and weird other indeterminates are natural radio? Ive added Mitch OT and VO1NA to my Argo screen captures on the web site making a total of 4 now.

The X-ray level from Geos is very low (B3-Class). I found in the past that events like that normally coincide with, at least, an M-Class flare. C-class can cause small enhancements on more local paths. The last C-Class was on the 22nd (a C5 just around 0700z). There was a minor geomag storm which drove the Kp up to 5 between 0900 and 1200z, but that doesnt normally give that kind of effect, and no increase in the proton flux. MMMMMmmmm fascinating !!

I did a stint of 160m operation from 9L1 in 1964. The best time was in January and the worst July to September. I don't know if 9G1 is the same. I will be going into hospital tomorrow, to get the plumbing sorted out, and expect to be back in about 10 days - in time for the 16th to the 24th.

well it would be great to see an American LF signal after all, despite the sad and hard-to-understand fact of the FCC's denial of a 136kHz ham band.

Receiving is always a little more difficult here in Central Europe 'cause we got "both ends burning"... lots of DCF39 Luxembourg IM at the top, while on the bottom DCF42/49 TX-intermodulation bursts come in, and SXV from Greece becomes quite strong at night.

Their current FSK spectrum (main peaks at 135683 and 783) has several sidebands, with a spectral density roughly 10dB over background noise near 135922. However there is a pronounced minimum now between 135890 and 135900Hz which could be useful. The problem is that as their frequency is drifting, the position of the clear gap may vary from week to week (see pic).

Kind regards
Markus, DF6NM

I also favour the low end of the band as Luxembourg effect QRM is bad at the
HF end in the evenings.

Hi all,
 
that's what I believe also. Has anybody thought how we could have a "grand farewell bash"? I have re-arranged my holiday dates to get home on 24th so as not to miss any fun at the party.
 
Been off air for several weeks due to (among other things) building works on a palatial new coil housing in uPVC, family matters, and the arrival last week of the new "made-to-measure" computator complete with TFT display.
Lovely, except that the SMPSU in said display puts a wonderfully wavy line on 137.700 plus or minus wanderings. Direct pickup by coil/antenna seems to be the problem.Ye olde Bacofoil dodge reduces it to manageable proportions at the cost of the aesthetics of the workstation, and with any luck the flitting of the coil to its new home will improve things even more.
Hope to have the works completed before June 1st  -  just in case, so advance apologies for any strange noises on the bands during the next few days.

I also favour the low end of the band as Luxembourg effect QRM is bad at the HF end in the evenings. But if we use that frequency for receive, is the high end (eg 137.770kHz) OK for receiving Eu in the USA?

So I am pleased to hear that Lawrence may be beaconing some time in the future. Its a long time since I did any listening/looking T/A.and welcome the opportunity . I think it would be best to keep clear of top end of the band which might be in use for local QRSS contacts,and also when looking for VA3LK I had strong Loran interference on 137.7446.

I believe Andre' is referring to Part 5 of the FCC Rules and Regulations, under which the FCC issues licenses for experimental work. Part 15 covers low power, license-free operation and incidental-radiation devices. It contains the provisions under which existing US LowFERs work. He is correct that Part 5 licensees can only communicate among stations covered by the same license. (And then, only if communication techniques are part of the authorized experimental program. A station that is authorized specifically for antenna testing, for instance, might only be allowed one-way transmission.) We do not have anything nearly as progressive as NoV under US ham rules. The closest we have under Part 97 is Special Temporary Authorization (STA), which allows for experimentation with non-standard modes or emission characteristics, but only within an existing recognized ham band. 73 John From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 11644 invoked from network); 19 May 2003 21:17:58 -0000 Received: from murphys.services.quay.plus.net (212.159.14.225) by mailstore with SMTP; 19 May 2003 21:17:58 -0000 Received: (qmail 24337 invoked from network); 19 May 2003 21:17:40 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from post.thorcom.com (193.82.116.70) by murphys.services.quay.plus.net with SMTP; 19 May 2003 21:17:40 -0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 X-SQ: A Received: from majordom by post.thorcom.com with local (Exim 4.14) id 19Hs0I-0004zC-6K for rsgb_lf_group-outgoing@blacksheep.org; Mon, 19 May 2003 22:17:06 +0100 Received: from [212.125.75.12] (helo=mail4.messagelabs.com) by post.thorcom.com with smtp (Exim 4.14) id 19Hs0C-0004z3-Fk for rsgb_lf_group@blacksheep.org; Mon, 19 May 2003 22:17:00 +0100 X-VirusChecked: Checked X-Env-Sender: William.Ashlock@bocedwards.com X-Msg-Ref: server-8.tower-4.messagelabs.com!1053379005!52217 Received: (qmail 25764 invoked from network); 19 May 2003 21:16:45 -0000 Received: from ukfw1.ge.boc.com (193.131.2.157) by server-8.tower-4.messagelabs.com with SMTP; 19 May 2003 21:16:45 -0000 Received: from exc_wil04.edwards.boc.com ([162.118.144.226]) by exc_cra03.edwards.boc.com with SMTP (Microsoft Exchange Internet Mail Service Version 5.5.2653.13) id LB21AP0S; Mon, 19 May 2003 22:21:54 +0100 Received: by EXC_WIL04 with Internet Mail Service (5.5.2653.19) id ; Mon, 19 May 2003 17:17:24 -0400 Message-ID: From: "Ashlock,William" To: rsgb_lf_group@blacksheep.org Date: Mon, 19 May 2003 17:17:21 -0400 MIME-Version: 1.0 X-Mailer: Internet Mail Service (5.5.2653.19) Subject: RE: LF: No LF Band in US Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 8bit X-Spam-Status: No, hits=-12.8 required=5.0tests=EMAIL_ATTRIBUTION,ORIGINAL_MESSAGE,QUOTED_EMAIL_TEXTversion=2.53 X-Spam-Checker-Version: SpamAssassin 2.53 (1.174.2.15-2003-03-30-exp) X-SA-Exim-Scanned: Yes Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group X-SA-Exim-Rcpt-To: rsgb_lf_group-outgoing@blacksheep.org X-SA-Exim-Scanned: No; SAEximRunCond expanded to false Andre, Did you mean to say "Part 5" licenses below?

In fact AMRAD has held such a license to transmit on 136 kHz for several years, and we have --off and on-- run a beacon (WA2XTF) on that frequency for at least three years. It was heard regularly in London (the Ontario, Canada variety). The problem is that, although we are all licenses amateurs, when we do operate under a Part 15 license, we are forbidden from communicating with other amateurs. Hence we can beacon, but not exchange messages with other hams.

In fact AMRAD has held such a license to transmit on 136 kHz for several years, and we have --off and on-- run a beacon (WA2XTF) on that frequency for at least three years. It was heard regularly in London (the Ontario, Canada variety). The problem is that, although we are all licenses amateurs, when we do operate under a Part 15 license, we are forbidden from communicating with other amateurs. Hence we can beacon, but not exchange messages with other hams.

Alan is correct when he says things have shown a sign of improvement but they have a long way to go before they are anything like normal. My frustration has always been that when I look at the propogation forecasts (I use a combination of DK0WCY and the site at http://www.hfradio.org/propagation.html). Inevitably when I check when I know conditions are lousy (and often not even hearing DK0WCY on 10144) it says conditions are 'Normal' when I know they are far from so! There seems to be a variance between the theoretical forecasts put out on these sites and how they relate to amateur experience. It was interesting to read some of the comments on the Elecraft reflector yesterday. They had arranged an 'Elecraft Net' on 18112 which turned out not to be very successful. At the time involved (2000z) propagation between USA and Europe was probably past it (I wasn't even bothering to listen). While some of the mid US stations commented that conditions were 'great' others on the East Coast and West Coast found them very poor - clearly propogation paths differ enormously between different areas, and those further south always fair far better than us in the UK. There is clearly a strong link between HF and LF propogation, as shown by Alan's very weak detection of CFH last week when the HF bands were to all intents and purposes dead. However I am not convinced that we should religiously believe the theoretical figures and there may also be openings when the theory indicates otherwise. This coming weekend I am hoping for a good bash at WPX CW so hoping things improve an awful lot before then! 73 Dave G3YMC dsergeant@btinternet.com http://www.dsergeant.btinternet.co.uk From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 15817 invoked from network); 19 May 2003 16:54:44 -0000 Content-Transfer-Encoding: 8bit Received: from netmail02.services.quay.plus.net (212.159.14.221) by mailstore with SMTP; 19 May 2003 16:54:44 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: (qmail 8269 invoked by uid 10001); 19 May 2003 16:54:44 -0000 Received: from post.thorcom.com (193.82.116.70) by netmail02.services.quay.plus.net with SMTP; 19 May 2003 16:54:44 -0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 X-SQ: A Received: from majordom by post.thorcom.com with local (Exim 4.14) id 19Hntl-0002rW-HG for rsgb_lf_group-outgoing@blacksheep.org; Mon, 19 May 2003 17:54:05 +0100 Received: from [147.197.200.9] (helo=hestia.herts.ac.uk) by post.thorcom.com with esmtp (Exim 4.14) id 19Hnth-0002rN-0g for rsgb_lf_group@blacksheep.org; Mon, 19 May 2003 17:54:01 +0100 Received: from gemini ([147.197.200.44] helo=gemini.herts.ac.uk) by hestia.herts.ac.uk with esmtp (Exim 3.22 #1) id 19Hnta-0004hk-00 for rsgb_lf_group@blacksheep.org; Mon, 19 May 2003 17:53:54 +0100 Received: from [147.197.232.252] (helo=rsch-15.herts.ac.uk) by gemini.herts.ac.uk with esmtp (Exim 3.33 #1) id 19HntY-0003BF-00 for rsgb_lf_group@blacksheep.org; Mon, 19 May 2003 17:53:52 +0100 Message-ID: <5.1.0.14.0.20030519161314.00acb0d8@gemini.herts.ac.uk> X-Sender: mj9ar@gemini.herts.ac.uk X-Mailer: QUALCOMM Windows Eudora Version 5.1 Date: Mon, 19 May 2003 17:53:52 +0100 To: rsgb_lf_group@blacksheep.org From: "James Moritz" MIME-Version: 1.0 X-MailScanner: No Virus detected Subject: LF: Earth experiments Content-Type: text/plain; charset=us-ascii; format=flowed X-Spam-Status: No, hits=0.0 required=5.0tests=noneversion=2.53 X-Spam-Checker-Version: SpamAssassin 2.53 (1.174.2.15-2003-03-30-exp) X-SA-Exim-Scanned: Yes Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group X-SA-Exim-Rcpt-To: rsgb_lf_group-outgoing@blacksheep.org X-SA-Exim-Scanned: No; SAEximRunCond expanded to false Dear LF Group, In the discussion over transmission lines, G3LDO said: >Just a thought. Where should you connect the system to ground if the >two components are some distance apart? Conventional wisdom suggests >it should be under the loading coil. It seems to me the earth connection should be where the return current flowing through the earth has the shortest, lowest resistance path, ie. directly under the antenna where the field is greatest. In an effort to test this, I did some experiments over the weekend. The antenna arrangement here has an inverted L antenna, with a loading coil and matching transformer about 10m from the shack, fed through about 15m of 50ohm coax. The ground consists of 6 x 1m copper pipe ground rods, distributed within about 3m radius of the loading coil. The shack end of the coax was also grounded through various ground rods around the house, plus the mains earth and gas and water pipes. With this arrangement, the total loss resistance of the antenna/earth combination was 36ohms. Disconnecting the antenna ground, so that all the ground current had to flow via the shack ground resulted in 37 ohms loss resistance. Isolating the shack ground using a common-mode choke in the coax feeder, so all the current flowed in the antenna ground, resulted in 37 ohms loss resistance too. With both grounds connected, an RF ammeter showed that about 90% of the ground current flowed through the antenna ground rather than via the coax braid. The shack and antenna grounds are both at one end of the 40m long wire antenna, so most of the current has to flow through the ground for some distance before reaching either earth connection. But if more ground rods are added under the length of the antenna further from the feed point, very little RF current flows in them. I think this is because the distributed inductance of the wire connecting the more distant ground rods to the common grounding point has a reactance that is large compared to the resistance of the ground connection. So I tried a "star" ground system consisting of 11 ground rods distributed around the centre of the antenna span with a radius of roughly 13m. Each rod was connected using 13m of wire to a central point insulated from ground, which was then connected back to the low-potential end of the matching transformer with a bus wire. In this way, all the ground current had to flow through an equal impedance, whichever ground rod it passed through, and checks with an RF ammeter confirmed the current in each ground rod was indeed roughly equal. With the shack ground isolated as before, the loss resistance was now 33 ohms, so a modest 11% improvement in antenna efficiency had been achieved. The loading coil inductance also had to be reduced slightly due to the added inductance in the ground connection. I then tried disconnecting some of the rods, to see how many were actually needed - the results were: 11 rods - 33R 8 rods - 34R 5 rods - 36R 3 rods - 41R 2 rods - 44R 1 rod - 55R So the resistance associated with a single rod is about 20 - 25 ohms; there is not much to be gained by having more than 5 rods. The best that was achieved was only about 2dB better than using a single ground rod. The ground at my QTH is a thick layer of clay, which seems to be waterlogged most of the time, so I imagine the ground conductivity is quite high. I expect grounding arrangements would have more effect where the ground conductivity was lower, and the loss resistance was higher to start with, or the antenna was very large and had a lower loss resistance - does anyone have any experience of this? If you have similar ground to mine, the moral of the story would seem to be that the location of the ground system is not very critical provided it is reasonably close to the antenna, and that there is little to be gained by having more than about 5 ground rods, unless the loss resistance of the antenna is very low to begin with.

The NOAA SEC is predicting and possible unsettled period today 19th due to another coronal hole, but so far conditions seem to be improving over the longer distances. Brian's plot of DCF39 is showing some peaks over the average in the overnight period, and my plot of CFH last night shows some reasonable levels. Steve's plot od DCF39 is still disappointing. His noise is fairly high, and the received levels are some 20 dB below the best seen (mid January this year) These conditions are confirmed by the fact that I received a complete call-sign string from Joe VO1NA on the pre-dawn morning of the 18th. Joe was transmitting what he refers to as QRSS80 (it is a hardware keyer timed with a 555 timer chip) he has now 115 watts from a single ended Class-E (see my web site) stage driven by a Siemens PS. Joe's aerial is an L which is only about 12m high at present (winds have precluded him climbing right up the 25m tower to fix the halyards higher) with about 150m or top-load wire. This path is obviously easier than to the States or than to Mitch, as Newfoundland is probably at least 1000kms nearer, and mostly over water. Joe has reported receiving Brian almost every night Brian has transmit.

The normal procedure used for analogue pointing does not seem to > work for digital. IMHO, if you have a good analog picture, there is an adequate signal to get a reliable lock. Your problem is probably other than dish alignment. Is your analog receiver a separate unit? If so, are both receivers connected? Which one is controlling polarity and band? Is this 22 kHz band switching, or are you using DiSEqC or other fancy control? First, make sure that the analog program you are receiving is from the right satellite. If one is available, try to receive an analog program from a transponder on the same polarity and band as the digital signal you are seeking. If not, at least check that your analog program goes away when you change polarity and/or band. Try to receive a digital package other than the one you really want to watch. Make sure you entered the right SR. Try transponder frequencies +/- 1, 3, and 5 MHz from the correct value. A signal with a high SR, e.g. 27500, will be easier to lock than a narrow one. Choose an unencrypted signal. If you're trying to receive something exotic, aim your dish at e.g. Astra or Hotbird for initial testing. Be aware that if your dish is smaller than 1 m, an alignment meter can give misleading results, because you start to see signal from an adjacent satellite, before the signal from the desired bird falls off very much. If you still have trouble, let me know your setup: dish size, LNB type, receiver model(s). 73, Stewart From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 7946 invoked from network); 18 May 2003 10:39:25 -0000 Received: from netmail01.services.quay.plus.net (212.159.14.219) by mailstore with SMTP; 18 May 2003 10:39:25 -0000 X-Priority: 3 Received: (qmail 16695 invoked by uid 10001); 18 May 2003 10:39:25 -0000 X-MSMail-Priority: Normal Received: from post.thorcom.com (193.82.116.70) by netmail01.services.quay.plus.net with SMTP; 18 May 2003 10:39:25 -0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 X-SQ: A Received: from majordom by post.thorcom.com with local (Exim 4.14) id 19HLWx-0006HS-3W for rsgb_lf_group-outgoing@blacksheep.org; Sun, 18 May 2003 11:36:39 +0100 Received: from [165.212.11.110] (helo=cmsrelay01.mx.net) by post.thorcom.com with smtp (Exim 4.14) id 19HLWs-0006HJ-A5 for rsgb_lf_group@blacksheep.org; Sun, 18 May 2003 11:36:34 +0100 Received: from cmsapps01.cms.usa.net (165.212.11.136) by cmsoutbound.mx.net with SMTP; 18 May 2003 10:35:52 -0000 Received: from usa.net [81.211.141.186] by cmsapps01.cms.usa.net (ASMTP/dibene@usa.net) via mtad (C8.MAIN.3.05) with ESMTP id 655HeRkjx0361M36; Sun, 18 May 2003 10:35:49 GMT Message-ID: <3EC7623B.9070200@usa.net> Date: Sun, 18 May 2003 12:36:43 +0200 From: "Alberto di Bene" User-Agent: Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.0.2) Gecko/20030208 Netscape/7.02 X-Accept-Language: en-us, en MIME-Version: 1.0 To: rsgb_lf_group@blacksheep.org References: <000c01c31c61$8b4d24c0$82e4fc3e@l8p8y6> <002201c31c75$8b709b30$0700000a@parissn2> <001201c31d0e$14f42c80$46d0fc3e@l8p8y6> Subject: LF: Re: SAT Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 8bit X-Spam-Status: No, hits=-18.9 required=5.0tests=EMAIL_ATTRIBUTION,REFERENCES,USER_AGENT_MOZILLA_UAversion=2.53 X-Spam-Checker-Version: SpamAssassin 2.53 (1.174.2.15-2003-03-30-exp) X-SA-Exim-Scanned: Yes Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group X-SA-Exim-Rcpt-To: rsgb_lf_group-outgoing@blacksheep.org X-SA-Exim-Scanned: No; SAEximRunCond expanded to false hamilton mal wrote: >I need some sort of device to accurately point the dish towards the >satellite.

It has a needle meter, and a buzzer with a sensitivity control. You first aim the dish with a couple of degrees of accuracy, then do a fine positioning either looking at the needle or listening to the buzzing tone. It has a very sharp maximum when the disk alignment is optimal, i.e. the signal strength is peaking.

Most digital receivers have an LED or onscreen indicator for sync. If this is off, make sure your transponder frequency and sample rate are entered correctly. Make sure you are using the correct polarity, and LNB band if applicable. If the LO in your LNB is off frequency, you may be able to get a lock by entering a transponder frequency 2 or 3 MHz above or below the actual. If the sync indicator is on, and you still can't get the program, it may be encrypted with a system for which you have no CAM. Check lyngsat, satcodx, or a recent satellite TV magazine. Some signals don't have an accurate directory - you may need to enter the PIDs manually. If your receiver doesn't permit this, you are out of luck. 73, Stewart ----- Original Message ----- From: "hamilton mal" To: Sent: Saturday, May 17, 2003 12:45 PM Subject: LF: SAT Very little acty this weekend so far on LF so I am fiddling about trying to RX digital Sat TV with little success so far.

Pond. I saw an FSK signal appear weakly last night at about 2230z, but later
when I decided to switch on the logger, I realised it seemed to have gone
off. Then I saw that there was a wide hump of noise centred on 137 and
assume they switched to GMSK. This has a wider band width than FSK and was
showing at + / - 150Hz even over here. From my previous measurements it
seems to give similar reading but one does need to get is all in the RX
bandwidth.

This ridiculous over-concern with 1w ERP could be turned around... As a concerned US citizen, why not take the following scenario to the Dept of Homeland Security:- If you were deliberately setting out to cause trouble, then rather than using a normal radio antenna, more efficient coupling of LF power to overhead transmission lines could be achieved with a horizontal loop of wire directly underneath the overhead wires. Marry this with an LF power source capable of putting several hundred watts into the coupling loop (several tried and tested designs exist...), and interference currents will be generated far larger than anything feasible from proposed amateur operations. Furthermore, such equipment can easily be made portable so that it could be positioned anywhere along hundreds of miles of transmission lines, and could be easily concealed to the point where even an intensive search of the area probably wouldn't find it. Very little radiated signal would be produced in the far field, so D/F techniques would be little use in locating the equipment either. Thus, a small number of terrorists with a budget of a few hundred dollars each to spend on perfectly mundane, locally available, electronic components could shut down the US grid at will and at very little personal risk, effectively holding the entire nation to ransom. Of course, if anyone actually tried it, it probably wouldn't have the slightest effect 99.99% of the time - but if the utilities were to claim that, they would be directly contradicting their position over 136kHz. If they stated that their systems had somehow been upgraded to be immune to this type of attack, then they would also be protected against amateur radio transmissions, and their objections to the 136kHz allocation would again evaporate. There is a power line not far from my QTH which continuously radiates a 136.65kHz carrier - I'm almost tempted to go and try it; after all, it would be perfectly legal here. So if you hear I was dragged away by tall gentlemen in dark suits with short haircuts, you will know what happened... :-) Cheers, Jim Moritz 73 de M0BMU From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 18220 invoked from network); 15 May 2003 16:42:57 -0000 Received: from warrior.services.quay.plus.net (212.159.14.227) by mailstore with SMTP; 15 May 2003 16:42:57 -0000 Content-Transfer-Encoding: 8bit Received: (qmail 14376 invoked from network); 15 May 2003 16:43:01 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: from post.thorcom.com (193.82.116.70) by warrior.services.quay.plus.net with SMTP; 15 May 2003 16:43:00 -0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 X-SQ: A Received: from majordom by post.thorcom.com with local (Exim 4.14) id 19GLnL-0005Z5-VQ for rsgb_lf_group-outgoing@blacksheep.org; Thu, 15 May 2003 17:41:27 +0100 Received: from [212.125.75.12] (helo=mail4.messagelabs.com) by post.thorcom.com with smtp (Exim 4.14) id 19GLn7-0005Yw-K6 for rsgb_lf_group@blacksheep.org; Thu, 15 May 2003 17:41:13 +0100 X-VirusChecked: Checked X-Env-Sender: William.Ashlock@bocedwards.com X-Msg-Ref: server-8.tower-4.messagelabs.com!1053016867!5639 Received: (qmail 1843 invoked from network); 15 May 2003 16:41:07 -0000 Received: from ukfw1.ge.boc.com (193.131.2.157) by server-8.tower-4.messagelabs.com with SMTP; 15 May 2003 16:41:07 -0000 Received: from exc_wil04.edwards.boc.com ([162.118.144.226]) by exc_cra03.edwards.boc.com with SMTP (Microsoft Exchange Internet Mail Service Version 5.5.2653.13) id J31X3PV1; Thu, 15 May 2003 17:46:14 +0100 Received: by EXC_WIL04 with Internet Mail Service (5.5.2653.19) id ; Thu, 15 May 2003 12:41:44 -0400 Message-ID: From: "Ashlock,William" To: rsgb_lf_group@blacksheep.org Date: Thu, 15 May 2003 12:41:44 -0400 MIME-Version: 1.0 X-Mailer: Internet Mail Service (5.5.2653.19) Subject: RE: LF: No US Ham Band Content-Type: text/plain; charset=iso-8859-1; format=flowed X-Spam-Status: No, hits=0.0 required=5.0tests=noneversion=2.53 X-Spam-Checker-Version: SpamAssassin 2.53 (1.174.2.15-2003-03-30-exp) X-SA-Exim-Scanned: Yes Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group X-SA-Exim-Rcpt-To: rsgb_lf_group-outgoing@blacksheep.org X-SA-Exim-Scanned: No; SAEximRunCond expanded to false >Despite assurance from ARRL that an amateur would have to be within a >few 100 yards of the line for there to be any problem, at which >distance the power line QRM would be horrendous, FCC have gone along >with the power companies in rejecting the proposals.

What if one of the major TV networks were put on a typical 2 min 'newsy item' where one of us, in an interview, would state that the power grid is vulnerable (by the power companies own admission) to a level of power that could easily be generated from an automobile parked under a high tension line with nothing more showing that a typica AM antenna? A statement could be added that translates the 1w ERP max at ~300ft to the power needed at, say, 50ft from the line to cause a problem (Is that ~30mw?). You know the analogy that the public understands: "Less than the power to operate a flashlight". Add a few juicy doomsday tourist scenarios and the general public (politicians?) would be up in arms! I'm sure the power companies would quickly counter with a statement indicating that they have designed their system to be safe from any mobile RF power source short of, say, 1KW?. Then we'd have them!!

Also, in a compromise with government users, the Commission decided to give amateurs five discrete 2.8-kHz-wide channels in the vicinity of 5 MHz instead of the 150-kHz band ARRL had requested. In its Notice of Proposed Rule Making a year ago, the FCC appeared inclined to go along with both ARRL requests. The FCC did agree in a Report and Order released May 14 to elevate the Amateur Service, but not the Amateur-Satellite Service, to primary status at 2400 to 2402 MHz. The changes to Part 97 go into effect 30 days after publication in The Federal Register, which has not yet happened. ''We are disappointed that the FCC could not see its way clear to providing even a narrow LF allocation to the amateur service, given earlier encouraging signs and the general trend in other countries,'' ARRL Chief Executive Officer David Sumner, K1ZZ, said of the FCC's decision. The FCC, however, found itself more persuaded by arguments from electrical utilities and other commenters that amateur operation at 136 kHz might interfere with power line communications (PLC) used by electrical utilities to control the power grid. The FCC said a new amateur LF allocation is not justified ''when balanced against the greater public interest of an interference-free power grid.'' The FCC said amateurs wishing to experiment with LF could apply for experimental licenses or operate under existing Part 15 rules on that part of the spectrum. ''We will not jeopardize the reliability of electrical service to the public,'' the FCC concluded. The granting of just five spot frequencies--5332, 5348, 5368, 5373, and 5405 kHz--at 60 meters was less of a surprise given opposition expressed last fall by the National Telecommunications and Information Administration (NTIA). The NTIA had cited a possible need for the requested band by federal government users and proposed the five specific frequencies for amateur use on a secondary basis. The FCC has granted operation on USB (2K8J3E emission) only, with a maximum effective radiated power limit of 50 W relative to a 0 dB gain antenna--a half-wave dipole. The channels--each with a maximum permissible bandwidth of 2.8 kHz--will be available to General and higher class licensees. ''While the new amateur privileges at 5 MHz are not as flexible as we had hoped, we recognize that much has changed since the ARRL petition for rulemaking was submitted to the FCC in the summer of 2001,'' Sumner said. ''Federal agencies with homeland security responsibilities have renewed interest in HF radiocommunication.'' Sumner said the ARRL was pleased to see 2400-2402 MHz upgraded to primary. ''The upgrade of the 2400-2402 MHz amateur allocation to primary provides a seamless primary allocation from 2390 to 2417 MHz, in addition to the secondary allocations of 2300-2310 and 2417-2450 MHz,'' he said.

I downloaded and read the full FCC report (linked from the ARRL site) which explains their decisions in more detail. The problem is possible interference by amateur signals to the PLC system used by the power line companies to control power line switching - note that this is nothing to do with PLT, or broadband, but a FSK system they use. Despite assurance from ARRL that an amateur would have to be within a few 100 yards of the line for there to be any problem, at which distance the power line QRM would be horrendous, FCC have gone along with the power companies in rejecting the proposals. The fear is of switching relays being incorrectly turned off by amateur interference and causing power blackouts. Of course a system (in itself an unlicenced user of the band) which does not fail safe in these situations is badly designed anyway. The document is worth reading, but somewhat depressing. Both in the 136 case and in the 5MHz one they have gone 100% with the objectors and the amateur case has been totally ignored. If you download it note that it is a very bloated Word document at 1.3Mb. In pdf it comes down to 275k, and saved in Open Office format (zipped XML) it is a mere 49k!! 73 Dave G3YMC dsergeant@btinternet.com http://www.dsergeant.btinternet.co.uk From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 5500 invoked from network); 15 May 2003 12:19:26 -0000 Received: from netmail01.services.quay.plus.net (212.159.14.219) by mailstore with SMTP; 15 May 2003 12:19:26 -0000 X-Priority: 3 X-MSMail-Priority: Normal Received: (qmail 11204 invoked by uid 10001); 15 May 2003 12:19:26 -0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Received: from post.thorcom.com (193.82.116.70) by netmail01.services.quay.plus.net with SMTP; 15 May 2003 12:19:26 -0000 X-SQ: A Received: from majordom by post.thorcom.com with local (Exim 4.14) id 19GHgy-0002pa-KT for rsgb_lf_group-outgoing@blacksheep.org; Thu, 15 May 2003 13:18:36 +0100 Received: from [149.174.40.2] (helo=siaab1ab.compuserve.com) by post.thorcom.com with esmtp (Exim 4.14) id 19GHgs-0002ow-Mk for rsgb_lf_group@blacksheep.org; Thu, 15 May 2003 13:18:30 +0100 Received: (from mailgate@localhost) by siaab1ab.compuserve.com (8.12.9/8.12.7/SUN-2.7) id h4FCHsHB004404 for rsgb_lf_group@blacksheep.org; Thu, 15 May 2003 08:17:54 -0400 (EDT) Date: Thu, 15 May 2003 08:17:30 -0400 From: "Holger 'Geri' Kinzel, DK8KW" To: rsgb_lf_group@blacksheep.org Message-ID: <200305150817_MC3-1-38E7-4E0D@compuserve.com> MIME-Version: 1.0 Content-Disposition: inline Subject: Re: LF: No US Ham Band Content-Transfer-Encoding: 8bit Content-Type: text/plain; charset=ISO-8859-1; format=flowed X-Spam-Status: No, hits=0.0 required=5.0tests=noneversion=2.53 X-Spam-Checker-Version: SpamAssassin 2.53 (1.174.2.15-2003-03-30-exp) X-SA-Exim-Scanned: Yes Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group X-SA-Exim-Rcpt-To: rsgb_lf_group-outgoing@blacksheep.org X-SA-Exim-Scanned: No; SAEximRunCond expanded to false Dear LF-Folks, I am very disappointed about this FCC-decision.

Here's a 1 kHz-wide shot of how it looks this morning. http://webpages.charter.net/w1tag/files/cfh.jpg It does take up some room, and even though the static crashes were a lot fewer last night, I could not see my usual Loran lines around 137.774. I have no way to know if that was due to the 137.0 signal, or not. In any case, it was hardly the biggest disappointment of the day.

I saw an FSK signal appear weakly last night at about 2230z, but later when I decided to switch on the logger, I realised it seemed to have gone off. Then I saw that there was a wide hump of noise centred on 137 and assume they switched to GMSK. This has a wider band width than FSK and was showing at + / - 150Hz even over here. From my previous measurements it seems to give similar reading but one does need to get is all in the RX bandwidth. I hope the noise is not too wide on that side, and am sorry to see the FCC refusal after all this time.

Its nice to know that I do not have to go out looking for a break in my aerial :-)) Markus, yes the "filtering" to avoid logging the crashes, requires a little thought. I use a slightly easier algorithm. I take six samples at 10 sec intervals and throw all away but the lowest value. I also have a long time constant on the detector (about 3 secs). I am not sure that that is the best way to do it but is gives a smooth line. I did post my plot to my Propagation Report web page.

To cope with the current high level of QRN, I have now implemented a special averaging strategy: Each column in the final spectrogram is a 15-second weighted power-average of about 500 10.8Hz-resolution FFT's. The weight factor applied to a single spectrum is taken proportional to the inverse square of its total power. In effect, this type of averaging strongly prefers the quiet periods, and practically clears out the crashes. 73 de Markus, DF6NM Alan Melia wrote: Hi all despite a definite "switch-off" at about 2400z on the 12th, I was sure I saw a weak FSK trace on ARGO at about 2320z last night (13th) My logger was started but the plot is wery weak. The line definitely seems to be above the noise, but at such low levels I cannot be sure that I was not measuring something else. Can any of the N.American stations confirm activity of CFH last night?? If this is confirmed, this is by far the lowest signal level received, and there is no history of them ever running a QRP mode.

If anyone on this group used an earlier version of it:
There is an update of the 'complex-calculating text editor' at
  http://www.qsl.net/dl4yhf/calc_ed.html


What's that ?
A small notepad-like text editor, which can calculate complex numeric expressions, like:
1/(2*pi*sqrt(1.4nF*1mH))  =: 134510
1kOhm||2kOhm||3kOhm  =: 545.455
 [ ||  is the 'parallel' operator,   A||B = (A*B)/(A+B)  ]
The result from one calculation line can be re-used in the next, and when finishing, you can save the whole thing in a plain text file.

What's new ?
CalcEd can now plot functions in a graphic output window. Good for analysing AC networks, due to the possibility of complex numbers.
To make this at least a bit "on-topic" : I used this program to check the frequency responce of a bandpass for 136kHz ;-).

Yes, it's true.  Yours truly, K7CCC, will be moderating an "Intro to
Hellschreiber" forum at the Dayton Hamvention this year.  While by
no means an expert (just a ham who likes the mode), I'll be in Room
1 (forum no. 111) from 8:15 to 9a.m. or so on Friday, with handouts,
a computer and simulated QSOs.

I'm hoping to interest more folks in a very fun and interesting
mode, and show them that it's easy to get started (I'll leave the
*very* technical stuff to guys like Murray, Peter, et al!) and that
it works fine business!

If you're going to be in Dayton this weekend, please stop by the
forum, or barring that, you might find me taking a turn in the ARRL
booth occasionally. Maybe in the flea market hunting for sweep tubes
and 6GK6s (gotta feed the Swan radios....)

Anyway, thanks and very 73 to all,
Dave Hassler, K7CCC

On my PC it did not manifest... but anyway I have been able to reproduce and fix it. I am not releasing the correction yet, as first I want to find the cause of a small anomaly that shows only with Windows XP. Nothing serious, but I would like to understand what is causing it before releasing the amended version of Argo. Please leave me another day. 73 Alberto I2PHD ------------------------ Yahoo!

The PA is in my shack followed by a small coil 0,268mH with taps, then a 6m long insulated wire feeds the 2,7mH rubbish-bin coil, located outside under a roof of glass. The vertical wire follows. Additionally to the taps I can make a fine tuning by moving a bundle of four "steam radio" ferrite rods in the small coil. All this by comfortably sitting in an armchair, no remote control required. Hi Walter. This would not work for me because my antenna and loading coil are 50 metres away from the shack. My vertical system has the loading coil and matching coil all located beneath the vertical drop under the antenna. Once set up it does not need a lot of attention except I need to change frequeny. It seems very stable and does not change much with wx variations. Frequency changes are not often necessary for such a small band only 2 khz wide approx and I always search the band after a CQ for others on a different frequency, and I am sure others do the same. 73 de Mal/G3KEV 73 Walter DJ2LF -----Ursprüngliche Nachricht----- Von: James Moritz An: rsgb_lf_group@blacksheep.org Datum: Freitag, 9.

The PA is in my shack followed by a small coil 0,268mH with taps, then a 6m long insulated wire feeds the 2,7mH rubbish-bin coil, located outside under a roof of glass. The vertical wire follows. Additionally to the taps I can make a fine tuning by moving a bundle of four "steam radio" ferrite rods in the small coil. All this by comfortably sitting in an armchair, no remote control required. 73 Walter DJ2LF -----Ursprüngliche Nachricht----- Von: James Moritz An: rsgb_lf_group@blacksheep.org Datum: Freitag, 9.

I have always used this system and find that it works very well. I didn't have a name for it and just referred to them as the matching and tuning circuit and the loading coil. In my installation the two are displaced by around 2m with the "bit of wire hanging in the air" just over 2m high. I had never thought of it as a transmission line. With the arrangement used at Amberley museum the two components were displaced by around 8m. Just a thought. Where should you connect the system to ground if the two components are some distance apart? Conventional wisdom suggests it should be under the loading coil.

The idea is to have a loading coil at the feed point of the antenna as normal, but with about 90 - 95% of the inductance required to achieve resonance. This is then connected back to the shack by a single wire, where the other 5 - 10% of the inductance is located, which is made variable so that tuning can be performed in the shack. The feeder can be 10-20m or more, and a couple of metres or so off the ground without having much effect on antenna behaviour. The impedance that the feeder is operating at is some hundreds of ohms, comparable with the Zo of the wire feeder, so loss in the feeder is minimal - analogous to feeding an HF doublet antenna with open-wire balanced line. Another way of viewing it is as the same as having an elevated loading coil, but with the loading coil displaced horizontally instead of vertically. The advantage is that the single-wire transmission line only carries a few hundred volts, so normal HF wire antenna type insulation where the feeder comes into the shack is adequate. This allows you to locate the loading coil in the best possible position, and greatly reduces the insulation problems, losses, noise pick-up and fire hazard compared with having the loading coil inside the shack, while keeping the convenience of being able to tune the antenna from the operating position without needing a remote control. Since the feed point is located close to the transmitter, impedance matching to the TX output can be done in any way you choose without worrying about matching to an intermediate transmission line. I used this method successfully for some time witth my first LF antenna a few years ago. Also, we used this arrangement for the TX antenna on the Porthcurno expedition recently, with good results.

Looking for a few more mW on 73.Based on the theory that more wire in the air=less ground loss resistance,I increased the length of one of my top load legs by 20m.This involved another rope over a 60 foot oak tree, lots of bow and arrow work BUT instead of the modest increase in current that I expected it actually dropped by 0.25A. Experiance indicates that the new wire should be over "new" ground ie not too close to existing wires,unfortunately the new wire was rather close (about 10m at the far end) however what was more significant was that the new wire passed directly over a dense area of Rhodedendron bushes about 10-12 feet high, so it looks like the increase in"tree loss resistance" exceeded any reduction in ground loss due to the extra wire. Needless to say I am back to square one ! but watch that greenery its lethal to RF. 73 Laurie.

Series, "Radar System Engineering" published in 1947, the selection of 50 ohms was based on a practical compromise between the 77 ohm value giving minimum attenuation and the 30 ohm value giving maximum power transmission (based on maximum voltage gradient). Fairly obviously, insertion of a suitable dielectric was part of the way forward in the evolution of a practical flexible general purpose coaxial transmission line and the then newly developed polyethelene, when used as a dielectric, gave a characteristic impedance of somewhat more than 51 ohms. This evolved fairly quickly, especially in the USA, to the now standard 50 ohm figure. You can find a good summary of the derivation of the 'minimum loss' impedance etc at the following URL- http://e-insite.net/ednmag/contents/images/47191.pdf and in a little more detail at- http://my.ece.ucsb.edu/bobsclass/134/Handouts/why50ohm.pdf My own primary reference on this is Chapter 1 of King, Mimno and Wing, "Transmission Lines, Antennas and Waveguides", McGraw-Hill, 1945. 73 Dave, ZL3FJ From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 17088 invoked from network); 9 May 2003 11:33:41 -0000 Received: from marstons.services.quay.plus.net (212.159.14.223) by mailstore with SMTP; 9 May 2003 11:33:41 -0000 Received: (qmail 4532 invoked by uid 10001); 9 May 2003 11:33:40 -0000 Received: from post.thorcom.com (193.82.116.70) by marstons.services.quay.plus.net with SMTP; 9 May 2003 11:33:40 -0000 X-SQ: A Received: from majordom by post.thorcom.com with local (Exim 4.14) id 19E67a-0000Uw-VE for rsgb_lf_group-outgoing@blacksheep.org; Fri, 09 May 2003 12:33:02 +0100 Received: from [62.253.162.46] (helo=mta06-svc.ntlworld.com) by post.thorcom.com with esmtp (Exim 4.14) id 19E67W-0000Un-Cp for rsgb_lf_group@blacksheep.org; Fri, 09 May 2003 12:32:58 +0100 Received: from mike1 ([80.4.107.45]) by mta06-svc.ntlworld.com (InterMail vM.4.01.03.37 201-229-121-137-20020806) with SMTP id <20030509113257.GNYU12018.mta06-svc.ntlworld.com@mike1> for ; Fri, 9 May 2003 12:32:57 +0100 Message-ID: <000501c3161f$04f26ea0$2602a8c0@WorkGroup> From: "Mike Dennison" To: rsgb_lf_group@blacksheep.org References: <3EBB9DF3.31816.1561410@localhost> Date: Fri, 9 May 2003 12:34:56 +0100 MIME-Version: 1.0 X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.50.4133.2400 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Subject: LF: Re: Activity?

Wil - pa0bwl -----Original Message----- From: Alan Melia [mailto:Alan.Melia@btinternet.com] Sent: Friday, May 09, 2003 1:33 AM To: LF-Group Subject: LF: Cantat submerged cable system Hi Johan and Jim, as Johan will well remember (I have bored him with personal e-mails before) I was involved peripherally in Cantat and in the later transistor cable systems. I can conform the cable was a nominal 50 ohms. What you have to remember is that a whole load of this was under many thousands of feet of water, which presumably has some effect on the dimensions !! I must ask one of my old buddies if 54 ohm coax cable becomes 50 ohms if you squeeze it hard !! I can also confirm the + / - 7kV power feed to the ends. One of the jobs I had was advising on protecting the transistor amps in the later cables from the eventuallity of a disgruntled fisherman taking his axe to a trawl-snagged cable. You can imagine what happens when 7000m of 50ohm coax (300pF per metre) charged up to 7kV is suddenly shorted by the axe blade. I understand from oft repeated anecdotes that the result was quite spectacular, and there was not a lot of a "lumberjack style" long-handle axe blade left afterwards. Also the axeman had somwhat of a headache and tingling feeling, after he picked himself up. We must have been reasonable successful as I dont believe we lost a single repeater to that cause. Geomag storms were a problem.....it is quite some antenna when you get a signal of about 4kV at the terminals !! I think it operated like a center-tapped single turn loop...more like a simple generator. It was usual to lose an hour or so of traffic time I believe when conditions were bad. I only think I am glad it was not me manning the power-feed shed on some lonely beach under those conditions. In Cantat the amps consisted of 3 valves in cascade (sons of the SP41 !!) sat in the middle of a bridge of directional filters so that it amplified sigs going both ways. The DC was stripped off by a LPF and the HT was developed across zener I believe. I have a sample of the later transistor-amp power-zeners. Yes the path loss may have been more than the Satellite link, but it didnt cost as much to lay and commission. I have not checked but I believe the cable is still usable over 40 years after it was commissioned, but I suspect a lot of the terminal gear has been stripped out. I bet there is not a lot of life in Telstar !! Back to topic ....would the fact that TV cable is normally semi air spaced account for the use of 72 ohms for our (in UK anyway) TV feeder??

I have an ITT technical journal, "Electrical Communication" from 1974 that contains some detailed articles about the Cantat-2 cable, 36 pages in all. Very interesting reading. One of the articles says that the cable Z was 54 ohms, so you were close. The cable had 473 repeaters and it was fed with +7kV at one end and -5.4 kV (adjustable -3.8..-7kV for compensation during magnetic storms) at the other end. The current was 490 mA. > I imagine they must have been designed with low loss in mind; Probably :-) According to the ITT publication, the total loss at the highest frequency (14MHz) was over 18360 dB (yes, read it again!). In comparison, an EME path will look like a short piece of copper wire... 73 Johan Bodin SM6LKM From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 4426 invoked from network); 8 May 2003 16:22:31 -0000 Content-Transfer-Encoding: 8bit Received: from murphys.services.quay.plus.net (212.159.14.225) by mailstore with SMTP; 8 May 2003 16:22:31 -0000 X-Priority: 3 Received: (qmail 13121 invoked from network); 8 May 2003 16:22:15 -0000 X-MSMail-Priority: Normal Received: from post.thorcom.com (193.82.116.70) by murphys.services.quay.plus.net with SMTP; 8 May 2003 16:22:15 -0000 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 X-SQ: A Received: from majordom by post.thorcom.com with local (Exim 4.14) id 19Do82-0002HC-4o for rsgb_lf_group-outgoing@blacksheep.org; Thu, 08 May 2003 17:20:18 +0100 Received: from [147.197.200.9] (helo=hestia.herts.ac.uk) by post.thorcom.com with esmtp (Exim 4.14) id 19Do7w-0002Gb-RM for rsgb_lf_group@blacksheep.org; Thu, 08 May 2003 17:20:12 +0100 Received: from gemini ([147.197.200.44] helo=gemini.herts.ac.uk) by hestia.herts.ac.uk with esmtp (Exim 3.22 #1) id 19DnMP-000420-00 for rsgb_lf_group@blacksheep.org; Thu, 08 May 2003 16:31:05 +0100 Received: from [147.197.232.252] (helo=rsch-15.herts.ac.uk) by gemini.herts.ac.uk with esmtp (Exim 3.33 #1) id 19DnME-0000oc-00 for rsgb_lf_group@blacksheep.org; Thu, 08 May 2003 16:30:54 +0100 Message-ID: <5.1.0.14.0.20030508141801.00b0dfb8@gemini.herts.ac.uk> X-Sender: mj9ar@gemini.herts.ac.uk X-Mailer: QUALCOMM Windows Eudora Version 5.1 Date: Thu, 08 May 2003 16:30:52 +0100 To: rsgb_lf_group@blacksheep.org From: "James Moritz" In-reply-to: <000601c3123c$8e7b7860$68c428c3@erica> References: <5.1.0.14.0.20030430120518.00ade070@gemini.herts.ac.uk> <001501c31001$6a079780$bee5fc3e@l8p8y6> <5.1.0.14.0.20030502115241.025564e8@gemini.herts.ac.uk> MIME-Version: 1.0 X-MailScanner: No Virus detected Subject: Re: LF: Mains Cable and other transmission lines Content-Type: text/plain; charset=us-ascii; format=flowed X-Spam-Status: No, hits=-22.9 required=5.0tests=EMAIL_ATTRIBUTION,IN_REP_TO,REFERENCES,REPLY_WITH_QUOTESversion=2.53 X-Spam-Checker-Version: SpamAssassin 2.53 (1.174.2.15-2003-03-30-exp) X-SA-Exim-Scanned: Yes Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group X-SA-Exim-Rcpt-To: rsgb_lf_group-outgoing@blacksheep.org X-SA-Exim-Scanned: No; SAEximRunCond expanded to false At 13:55 04/05/2003 +0100, you wrote: >After reading Jim's e-mail I searched through all my radio books >(Terman, Kraus et al) for enlightenment and the reason for 50ohms as a >standard is not discussed at all. >Any references Jim? Dear Peter, LF Group, I can't remember where I originally heard this - it gets a vague mention in several reference books, but the only discussion in any detail I could find was in a small book called "High Frequency Transmission Lines" by Willis Jackson, published in about 1945. The Zo for minimum loss is dependent mainly on the materials used for the conductors in the coax - for copper inner and outer it is 77ohms, but with copper inner and lead outer (I guess lead sheathed cables were popular then), it comes out to 93ohms. However, loss does not vary greatly with Zo. But this applies to an air dielectric; with a polythene dielectric, the optimum ratio of conductor sizes stays the same, but the presence of the polythene reduces the impedance. This would appear to make a Zo of 51ohms optimum for solid polythene insulated coax. I have some samples of old trans-atlantic telephone coax cable - according to the labels, they are from the TAT-1, TAT-II and CANTAT-2 cables. Measuring the dimensions of these, they work out to Zo of 57, 45, and 55 ohms respectively. I imagine they must have been designed with low loss in mind; which would tend to support the 51ohm figure. The calculation for max power handling is not straightforward - it depends on what the limiting factor is. In an air-dielectric cable limited by voltage breakdown , the optimum is 30ohms. But if the cable has solid dielectric, the breakdown voltage is higher, and other factors such as heat dissipation may be more important, favouring a higher Zo like 50ohms. The fact that Zo is proportional to the log of the ratio of diameters of outer and inner conductors severely limits the practical range - eg. if you wanted 600 ohm coax, then with a 1mm inner conductor, the outer would have to be about 4km in diameter! Low Zo is a bit more practical; a 4ohm cable would have the outer only about 10% greater in diameter than the inner, requiring a very thick inner conductor. I suppose this is why most coax is between 25 and 100 ohms.

There is a 2 to 3 day gap at LF before any radio effects of a geomag storm are felt, plenty time to be lazy and consult NOAA (like I do). I do have a load of measurements from Andy who built up one from a sensor (and probably a PIC) but we never raised much enthusiasm for it, or the output. The "centre of gravity" of the LF community is probably below the viewing zone as well......you will have to chase all those Scottish microwave men.

there must be lots of dusty cobwebs up there :-(  CFH was active all night and received here between about 23:00 and 5:00 UT. This colour spectrogram was taken with two orthogonal loops and no E-field-probe on the dual-channel RX, with trace-hue encoding the apparent angle of arrival with an 180° ambiguity. Note the variations over time due to ionospheric "ray-bending" or rotation of polarization.

John and Alan have confirmed that the rtty was CFH. 73 Joe VO1NA From rsgb_lf_group@blacksheep.org Sun Jan 01 00:00:00 1970 Return-Path: Received: (qmail 32238 invoked from network); 6 May 2003 10:01:02 -0000 Received: from warrior.services.quay.plus.net (212.159.14.227) by mailstore with SMTP; 6 May 2003 10:01:02 -0000 Received: (qmail 9410 invoked from network); 6 May 2003 10:01:06 -0000 Received: from post.thorcom.com (193.82.116.70) by warrior.services.quay.plus.net with SMTP; 6 May 2003 10:01:06 -0000 X-SQ: A Received: from majordom by post.thorcom.com with local (Exim 4.14) id 19CzEE-0008DO-OI for rsgb_lf_group-outgoing@blacksheep.org; Tue, 06 May 2003 10:59:18 +0100 Received: from [194.73.73.93] (helo=rhenium.btinternet.com) by post.thorcom.com with esmtp (Exim 4.14) id 19CzE9-0008DF-RA for rsgb_lf_group@blacksheep.org; Tue, 06 May 2003 10:59:13 +0100 Received: from host213-122-107-85.in-addr.btopenworld.com ([213.122.107.85] helo=Main) by rhenium.btinternet.com with smtp (Exim 3.22 #23) id 19CzE8-0004me-00 for rsgb_lf_group@blacksheep.org; Tue, 06 May 2003 10:59:13 +0100 Message-ID: <000e01c313b6$1d25d4a0$6507a8c0@Main> From: "Alan Melia" To: "LF-Group" Date: Tue, 6 May 2003 10:58:16 +0100 MIME-Version: 1.0 X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.50.4522.1200 X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106 Subject: LF: re 73k Content-Type: text/plain; charset=iso-8859-1; format=flowed Content-Transfer-Encoding: 8bit X-Spam-Status: No, hits=0.0 required=5.0tests=noneversion=2.53 X-Spam-Checker-Version: SpamAssassin 2.53 (1.174.2.15-2003-03-30-exp) X-SA-Exim-Scanned: Yes Sender: Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group X-SA-Exim-Rcpt-To: rsgb_lf_group-outgoing@blacksheep.org X-SA-Exim-Scanned: No; SAEximRunCond expanded to false Hi John, I will run my waterfall capture to the web site this morning now. It is available direct as http://www.alan.melia.btinternet.co.uk/periodic.htm (start up as soon as I posted this message) The scale is in Hz so add a "7" in front and you have the frequency. It is "right to left" as I use LSB to drop any Rugby signal over the edge of the filter. It seems fairly quiet this morning so far.

yes, I can confirm having seen CFH on 136.962/137.038 kHz from about 23:10 till QRT at 23:59 UT. When it is active, it must be much more of a problem than DCF39 is for us: DCF is a clean carrier more than a kHz above our band, except for FSK bursts once in every 10s. At my location 350 km south of it, the only real difficulty is strong nighttime Luxembourg effect impressed on it predominantly by 1323 kHz and 549 kHz BC transmitters. It is visible as blue patches in the background of the image.

I think it will have gone off again now. There is no sign of it here even on 3 sec ARGO. In the past two years it has been fired up occasionally for about a couple of hours. It did run about this time last year for about two days before going off again. It sounds like the old 82Hz shift FSK from what you describe. This is an indication of what the German stations have to contend with over here from DCF39 (which is 3dB stronger) Brian has a monitoring slot on his real time display which is devoted to CFH.

While observing the captures from my work site, I noticed that the receiver went very deaf around 1400 UTC. On arriving home, I was greeted with an awful racket, and on tuning around, found a very loud FSK station below Mitch's frequency. By the signal strength, it can only be CFH, and the frequencies on my Argo screen are 137.038 and 136.961 kHz. This is NOT good news if we're going to get a ham band down here! I'll be out this evening, but I wonder if any of you on this side of the pond could DF the station and confirm my observations. If Joe, VO1NA, is around, his receiver should be melting down.

I just worked RN6BN on Normal CW at 2139 utc he was 579 and gave me 539. A good solid QSO in spite of some QRN.
I think this is possibly the first hand sent normal speed CW qso between the UK and Russia on 137 khz. 
The rig this end was my home brew FET amp and the  4 x Inv L array for both TX and RX.
Not so much activity noticed this weekend although there were a few active from around EU.
Tnx Sam for the QSO and hope to do it agn soon.

Subject: LF: RN6BN

Good morning, dear friends,
    yesterday at abt 2100utc I saw YU7AR and RN6BN , both with strong signals and also audible. I did not call RN6BN because I suspected he was in QSO. Minutes later he gave cq with very strong signal (Argo -26dB). I called him and got ooo, he was also ooo here in JN59NO. But then both signals decreased rapidly and at least RN6BN disappeared.
 
I noticed the same thing a couple of nights ago and Alan, who keeps an eye on propogation make a comment about it.
It seems unusual for such a rapid disappearance.
 
 
 
 F6BWO called him, but no response. I have never before seen such an extreme change of propagation on LF.

Sorry for this being a bit off-topic.. but may be related to bat listening.

Does anyone here use the new Soundblaster Extigy audio device (for USB port), and has successfully convinced it to read "true" 96000 samples per second ?

The windoze driver seems to accept a sampling rate of 96kHz, but the spectrum above 24kHz is very weak. Signals above 24kHz produce weak aliasing effects, and signals above 26 completely disappear. I suspect, though the spec says "ADC with 96kHz sampling rate", this is only an internal value of the DSP, but not for practical applications. The windoze driver just seems to duplicate the samples, like it does for any 'old' soundcard. Sh**  !

Hope to return to LF soon; at the moment it's a waste of time trying to make 'real communication' here, no matter which mode...

Now come back from summer hose to my work. Yesterday we are was very near for succes. From 18.00 UTC we start to copy RN6BN in QRSS3. I job like computer. :-) I manually writed "dots" and "dashes" to paper and read this. :-) Signal was strong and clear 569 audiable copied. We are start call him at QRSS3 mode. But all evening only QRZ's from his side... :-(. It means, I think, very beeg enviroupment loses around my transmitting antenna. At 19.00 UTC signal RN6BN rising up 579-589 (same S\N result on my vertical and 1 metre diametr magnetic loop) - very strong. At 19.30 /utc we start to copy YU7AR in QRSS3 mode by ear, also strong and clear signal 559-569. But same QRG with RN6BN gave a QRM. DCF39 was not so strong like before day. Was only 50-55 db over noise in 100 Hz. I think Kp index rising. At 20.20UTC I started my QRSS20 beacon 137750 and 22.00 go to sleep. Today evening will make an antenna revision. I plain TX in beacon mode same QRG, like last nigt. Vlad.

What I have done is to analyse the geomagnetic activity over the last 10 years and plot out the number of sequenctial "quite" days where the Kp Index was less than 5. The period early in January suggested that this might lead to good conditions for paths of over 3000kms. The plots show that there are more long quiet spells as we drop down the solar cycle to the minimum, but there is still that amount of activity to give the conditions a kick in our favour. As the financial watchdogs say "past performance is no guarantee of future results", but it is a lot better than nothing. At the present I feel like an early weather forecasters when if you said "the weather tomorrow will be the same as today", you would be right about 52 % of the time....which is quite good going, but slightly dumb forecasting!! If you want to look at my ideas and plots they are now on my web site, go direct to the forecast page with http://www.alan.melia.btinternet.co.uk/forecast.htm Any thoughts, data, conflicting references etc, gratefully received. I hope it provides an incentive to keep working towards longer paths, and helps maybe understand how to pick the times to try for them.

I have been playing with a nominal "8 ohm" amplifier (actually two "4 >ohm" amps in bridging configuration), and using a 1:2 transformer that >presents 12.5 ohms to the PA when terminated in 50 ohms. As noted in the LF >Handbook, the output impedance of these amps can rise with frequency, and >there is plenty of power available with the 100 watt restriction. I tend to be in agreement with Mr. Mal on this subject. (Mark this date) Most amplifiers designed for audio use are slew rate limited when it comes to a full bore 137K sine wave because of the output devices. These amps usually check out OK on the bench with dummy loads but under 'real life' conditions there's little margin for transients - where the transient power (current times voltage) seen by the output devices can unknowingly be many times the maximum ratings.

He has been suggesting the use of a remote bat receiver with an 11m. transponder to my 850 for this purpose. He is not on e-mail and is presently off gallivanting somewhere in GM land but will be back next week and it will make a pleasant change for me to ring him up with an unusual query!

I have been playing with a nominal "8 ohm" amplifier (actually two "4 ohm" amps in bridging configuration), and using a 1:2 transformer that presents 12.5 ohms to the PA when terminated in 50 ohms. As noted in the LF Handbook, the output impedance of these amps can rise with frequency, and there is plenty of power available with the 100 watt restriction.

The choice is not entirely arbitrary - as I recall, 50ohm coax gives the best power handling capability for a given size of cable, while 75ohm gives the lowest loss. This is probably academic in amateur practice because the cost is usually a more significant consideration than the size! It is true that there is no particular need to design an LF system to use 50ohm impedances throughout. Provided the transmitter is provided with the load impedance for which it is designed, and you have some way of verifying that the load actually is properly matched to the TX, there is no problem. Standardisation is not an insignificant advantage however - designing everything to match to 50ohms means any transmitter, antenna tuner, power meter, tuning aid, low-pass filter, dummy load etc., etc., can be interconnected with predictable results, rather than having to devise suitable matching for each piece of equipment, or conversion factors for measurements. I take the view that you have to do some sort of impedance matching whether you want to or not, so designing the system to be 50 ohm throughout is rather like designing everything to run from 230V, 50Hz - it saves a lot of headaches! 50ohms is also a very practical value - manageable voltage and current, reasonable number of turns on a transformer, sensible values of L and C and so on. For example, 1200W from a Decca PA is 245V, 4.9A into 50ohms, which is quite manageable with ordinary coax (or mains...) cable and fittings, and other components. At 4 ohms, the current would be 17A, while at 600 ohms the voltage would be 850V, either of which would be more awkward. If the connection between TX and antenna is very short, the characteristic impedance of the transmission line connecting them is of little consequence. But the transmission line does not need to be wavelengths long before it starts to make a difference - 100m of RG58 has only about 0.5dB loss at 136kHz when in a matched system. while it should, for example, be possible to produce a 4ohms impedance at the TX end of the cable with a suitable matching network at the antenna end, the losses would be much higher - more like 10dB, mostly because of I^2R loss. But the losses would be only be slightly increased if the load at the TX had to be 75 ohms.

That is exactly the reason for using either 50 or 75 ohm transmission line, so that existing station test equipment can be used to test and monitor what is going on, otherwise its guesswork, like tuning for max smoke, which leads to buckets of exploded FETS. For those using the old audio amps, the preferred method is to couple the 4ohm audio output via a 10 mfd (non electrolitic) capacitor to a transformer designed for 4/50ohms then 50 ohm coax to the antenna loading coil, which is resonated at the appropriate frequency and impedence matched to the 50 ohm feed cable. This way is it easy to monitor what is going on with with the normal shack test equipment like Dummy load, SWR meter etc and is very economical with FETS , you should not really damage any because you can see danger coming and avoid it.

I have put a microphone on my SLM and have been receiving bats. I used a tiny electret condenser mic capsule on the input of the D2006, with the usual 1.5V cell and blocking cap to power the capsule. I was able to pick up bat sounds up to 55kHz. There were some clicks down at 22.5kHz, and some twitters around 45kHz. I think they are just the common or garden Pipistrelle bats. The bats are attracted to our big halogen security lamp, because of the insects that fly round it.

A proper LF RF amp is the only way forward. In the past reading from here, there were bucket fulls of explode FETS, in spite of some sophisticated mods they seemed to be unreliable, and using mains electric cable to the antenna loading inductor did not help.I could fill another COMIC with the stories that I have heard.

I have always designed my TX/RX system to use 50 ohms, that way I > know exactly how to measure the performance and it reflects on signals > radiated and received from this QTH. As far as I am aware I am the only one who has confessed to using electrical mains cable as transmission line so I guess the above is aimed at me. The distance from my LF transmitter to the primary loading and tuning coil is about two metres. This makes the length of my "transmission line" about .0009 wavelengths. To put that into perspective that is about 20mm on 14MHz. The impedance of the transmission system is unimportant, although there are certain considerations. For example, the distance from the Decca transmitter site to the antenna loading/tuning building was often a couple of km so a higher impedance system is chosen to reduce I^2 R losses. Early amateur home brew transmitters (and some commercial) using pye tanks were often designed with a nominal 75ohms output due to the availability of cheap television coax. 50ohm systems were chosen by equipment, test gear, coax cable and antenna manufacturers in the interests of standardisation - there is nothing 'magic' about 50ohms systems. There is no point in having an interim 50ohms section between a transmitter (that is other than 50ohms) and the antenna matching/loading system unless you wish to use it with a piece of existing or proposed 50ohm test equipment.

This looks like a nice tuning aid and judging by your signal it must be working, the only other signal from the South that moves my S meter is G3YXM, the others could certainly benefit from your meter. I wonder how it works with mains electric cable instead of coax to the antenna. Someone recently mentioned using this cable, and it seems popular on the South Coast.

I looked up what I did to the Maplin audio amp to increase the slew rate as described yesterday - The mods should also be applicable to the BK amp modules, judging by the circuit diagram on p4.23 of the "LF experimenter's source book" entitled "BK Electronics OMP MF300 Module". The major difference between the circuits is the BK amp has pairs of output devices in parallel (to drive a load of 4ohm instead of 8 ohm I guess), while the Maplin amp has single devices, and the input stage of the BK amp is biased by an active current source, while the Maplin amp has a simple resistor. There are a few other minor differences in component values mainly. See the attachment on the basis that a picture is worth 1000 words! In theory, to get an output voltage of 28V RMS into 4 ohms, giving 200W, a minimum slew rate of 2.82.pi.f.Vrms = 34V/us is required at 137kHz. My Maplin amp had a slew rate of 22V/us before the mods, and about 60V/us afterwards. The small-signal bandwidth was more or less the same at about 1.5MHz. Full output could then be obtained on 136k. Reducing the value of the 27p compensating capacitors will also increase the slew rate, but will inevitably also reduce the phase margin, and therefore increase the possiblity of the amp becoming unstable. It may or may not work OK, depending on the individual amplifier, and the effect of the frequency-dependent load impedance. It seems these audio amps are not as popular for LF these days, presumably because people are looking for higher power with better efficiency. But if the US LF allocation arrives with a 100W power limit attached, MOSFET audio amps could be a useful form of linear for the band.
