Dear Graham, LF Group, Still getting patchy copy with both Olivia and Domino EX11. The power levels seem to have dropped abruptly and then returned at least twice during the course of your test. Ther
Dear Johan, Graham, LF Group, If the shorter frame length is due to a sample rate error, there should also be a corresponding upward shift in the audio output frequencies. If we take M0LMH's figure o
Dear Mike, LF Group, Worked F4DTL this morning in DFCW - also copied, but missed F6BWO. No sign of OE5EEP here either, though I did see a very weak trace around 137.7 of something that might have bee
Dear Dave, Paul-Henrik, It could well be due to the increasing level of sidebands from Lakihegy, and associated Luxembourg effect noises. The attachment shows OH1LSQ mostly received on a N-S oriented
Dear Mal, LF Group, MOBMU now 192800 9 -13 0.2 -182 0 m0bmu 1091 30 Jim is this what u expect mal/g3kev Well, nearly - if the -182 is in the "DF" column, it would seem your RX is set 182Hz too high.
Dear Paul - Henrik, On the spectrogram I am seeing what could be very weak CW near to 136.400kHz, but there are several Loran lines close to this frequency, so it is a bit hard to tell. The spectrum
Dear LF Group, The beacon is now up & running. I see there are 4 spots already on the WSPR database. That was quick! There is noticeably more QRN tonight, so it will be interesting to see what happen
Dear All, M0BMU is now QRV overnight on WSPR 136.0kHz dial, 137.504kHz RF out. I shifted my TX frequency up by 4Hz to see if that is an improvement w.r.t. Loran. Any reports very welcome. Cheers, Jim
Dear Andy, Dennis, LF Group, Thanks for the PSK31 QSO and reports; it was nice to have signals that weren't down in the noise for once! I heard Andy testing and thought I would give it a try. I did s
Dear Nicolas, LF Group, Unfortunately not much chance of copying you here, due to very large "rustly bolt" (oh no not that again...) intermods from the local AM broacast stations at my QTH. Cheers, J
Dear LF Group, Am now running the WSPR beacon again on 136.0kHz "dial frequency", 137.500kHz RF out, 33% TX. I have temporarily raised the centre of the span of my antenna up to 15m (return of the ch
Dear LF Group, The M0BMU WSPR beacon is now running on 503.5kHz again, hopefully continuing overnight. Any reports would be very welcome. Cheers, Jim Moritz 73 de M0BMU
Dear Rik, Lee, LF Group, There are 2 database pages; the "old" and "new" format. You can get to the "old" from the link at the bottom of the "new" database. The Old database displays distance in mile
Dear John, Just put the TX back on for a few mins... Cheers, Jim Moritz 73 de M0BMU Just need some WSPR transmissions to decode, to prove the theory. The grabber image, updated every 5 minutes, is he
Dear John, Can do, if you like... will need to wait until about 2000utc while I sort out some other things. Is that OK? Cheers, Jim Moritz 73 de M0BMU Jim, LF, Are you, or any others, going to run WS
Dear LF Group The M0BMU WSPR Beacon went QRT at about 1000utc - thanks for all the reports. Best DX of the night was of course from WD2XSH/17 at 5245km, according to my software - thanks, Dave. Also
Dear Paul-Henrik, LF Group, It would appear you have QSY'd to 136.35kHz at around 1914utc... Still "O" copy in QRSS3 terms. Cheers, Jim Moritz 73 de M0BMU
Dear Jay, Vernon, LF Group, Jay - Thanks for looking - I can see that could be the problem! The WSPR signal has a bandwidth of around 6Hz, so the problem is finding that much of a gap between lines.
full acknowledgement each way so at least 96 bits need to be exchanged. If no further overhead is used, the QSO could therefore be completed in four days. ...But all this has been done before Andy, a
Dear LF Group, I have re-started the WSPR beacon on 503.5kHz (502kHz "dial frequency"). All reports will be very welcome. G4JNT is still QRV - solid copy here of course, with SNR plus a few dB. Cheer
