Dear LF group, I notice a few people have been having problems with insulators melting/cracking lately. I had problems with my insulators until I fitted some corona rings. What seems to happen when y
Dear LF Group, Congrats to G3LDO, VE1ZZ and VE1ZJ on their QSO - if nothing else, it proves that the SNR in both directions across the pond can be good enough to support 2 way communications in a rea
Dear LF Group, Re - the discussion of GPS derrived timing, DDS frequency sources, etc. It seems to me that increasing layers of complexity being proposed could do with some review before rushing head
Dear LF Group, Beacon signals for the last 2 nights were: Thurs/Fri 2010 - 0620, 30s dots, 2:1 dash/dot ratio, with 6wpm ID Fri/Sat 2110 - 0640, 30s dots, 3:1 dot/dash ratio, with 6wpm ID Both nights
Dear LF group, I transmitted beacon signals last night from 2010 until 0320 last night, on 135.9230kHz - using the same 1/2 hour per callsign format as before. I hope to be on again tonight. Thanks t
Dear Martin and Group, Most of the Loran noise seems to come from Lessay on the French coast, which is much nearer SE England than Wales, so one would expect the Loran noise to be relatively weak at
Dear LF Group, Transmitted beacon signals again on 135.923kHz last night, approx. 40s dashes, from 2000 until 0310. Before that, I heard a long series of CQ calls from DL3FDO on about 136.8. The gaps
Dear LF Group, In case anybody is trying to identify beacon signals, this is when I have been transmitting over the last few days, all on 135.9230kHz: 2047 on 3/2/2001 until 0350 on 4/2 - "M0BMU" at
<?color><?param0100,0100,0100>Dear LF Group,<br><br>I Think my E-mail account has started working again - about 80 E- mails turned up this morning. Glad to see some more signals have made it across t
Dear LF Group, Transmitted beacon signals from 2315 until 0420 last night; I QSY'd slightly to 135.9233 because my usual frequency was already in use when I started. Due to popular demand, some time
Dear LF Group, Sorry if I have not responded to any E-mails in the last day or so - the University E-mail servers have been doing something mysterious with incoming mail, and I have not been receivin
Dear LF group, Transmitted the usual beacon signal on 135.923kHz from 2000 until 0305 last night, apart from a period from 2205 - 2220 when I was making an adjustment to the antenna. For the record,
Dear LF group, I don't think it is possible for any one piece of software to be all things to all people - for the person who is trying to copy a QRSS signal, Argo is very well "tuned", but the trade
Dear Rick, LF group, Suppose the PLL is phase locked to the input signal, and suddenly a 180degrees phase transition occurs at the input. There would then be an error signal in the loop, which would
Dear Alberto, LF group, Adding an amplitude measurement capability to Argo/Spectran sounds like an excellent idea - it would enable a meaningful measurement of relative signal strengths to be made. D
Dear LF Group and Lowfers, Unfortunately, I was not able to transmit beacon signals last night due to a local power cut. However, I hope to be on tonight, between 0000 and 0200, on 137.500kHz again.
Dear Rik, LF Group, Another way of looking at this modulation method is that the high Q tuned circuit acts as a narrow filter which removes the unwanted sidebands of your "rude" BPSK - the signal wil
Dear Lowfers/LF Group, I operated the Wolf BPSK beacon on 137.500kHz last night from 0000 until 0400. Due to other commitments, I will not be QRV tonight, but the beacon will be operating again on Su
Dear LF Group, Will be running the WOLF beacon again tonight from 0000utc onwards, on 137.500kHz. If anyone would like to try some tests over the weekend, please let me know. Cheers, Jim Moritz 73 de
Dear LF group, ON7YD's comment that BPSK "gives away" 3dB is only true for the limiting case of phase-keying data input consisting of alternating 1s and 0s, and therefore a phase transition for every
