Hi Stewart I don't have Win98 myself, but several users have run WOLF under Win98 with no trouble. Please send me the failing console output, or tell me what OS error message you are getting, and I'l
A really good signal here as might be expected at 2100 I downloaded Wolf but it would not run on any of the systems I have (DOS, Win 3.11 and Win98). So unable to progress. Regards, Peter Dodd Web <h
I have now included the programs used to produce the LF antenna impedance signature shown in Fig 6.17 of the LF Experimenters HB. Just click on to 'AEGextra' from the home page. The site is given bel
I know that many CW ops were hoping that the use of continuous beacons just below 136.0 would be stopping soon - especially with the return of CFH. The reason for transatlantic QRSS operation below
I wish to thank all those who responded, both directly and through the reflector, to my query about zipping files. Regards, Peter, G3LDO Web <http://web.ukonline.co.uk/g3ldo>
I have a group of small DOS .exe files, plus some .txt data files (associated with measuring antenna feed impedance) that I would like to put on to my web site for the benefit of LF experimenters. I
Tonight G3XDV was "O" copy here . I believe his signals are the most weakly challanged that I have received across pond. I have sent pics to Mike. Congratulations to Mike and John. You only have to
Subject thread is heading back towards my territory! Same here - showing my age! The silver EF50's were service issue valves - VR91 for the RAF, ARP12 for the army. I suppose the navy must have had
The QRSS modes easily meet 2 and 3; in order to meet 1, a dot length of about 7 seconds maximum would be required. With the best possible conditions, I guess several stations might manage transatlan
One of the reasons that have probably made it difficult to receive my transmissions is that I haven't been transmitting. I put out an e-mail message on the 18th Feb that I would be transmitting on th
Many thanks to everone who responded to my comments on pre-amps and loops.I am still not certain what to do-but at least have some more ideas. I hope that the >resulting discussion was of general int

The LF Handbook errata has been updated and an improved image of Fig 3 to the 'Earthing Resistance of Antennae' posted. Regards, Peter, G3LDO Web <http://web.ukonline.co.uk/g3ldo>
Hi Andy, The normal mode helix was covered in some detail in a 1974 (!!) edition of Radio Communication with a set of empirically determined equations for calculating resonance and winding dimensions
Dusted the cobwebs of the LF transmitter and put the LF antenna up. Will be on just below Laurie at 135.920 from 2200z with QRSS, 20 sec dots. Regards, Peter, G3LDO Web <http://web.ukonline.co.uk/g3l
But before I go rushing off to Derek to buy some more, a simple sum casts some doubt on Peter's calculations. His loop has 2 metre sides and it has 4 sides so one turn equals 8 metres, not 16m, in wh
Does anyone have a description of how the helical antenna (not the axial mode antenna), like the one built by Toni HB9ASB, works? Tony made a lot of tests and concluded that most of the radiation cam
Our experiences seem to confirm that this sort of size (i.e. of the order of a couple of metres in diameter) and particularly the use of low resistance Litz is optimum. The number of turns is 10 in
In an attempt to improve the reception on 136kHz by cutting down the Loran racket I have, over a period of time, been experimenting with LF receiving loops. I now have one that works really well. It
There has been some discussion on methods of increasing activity on the 136kHz band. The main objection to contest activity seems to be that it would degenerate into a '599 QRZ' type contacts. The Wo
