Hi Markus, Joe, Domenico, LF

Extraordinary decode results, Markus. Congratulations for DX= ! Very good RX setup, Joe.
Thanks for trying to discover my signal.
I'm on air again for another attempt (with a little bit more power), sa= me parameters (2 sec, 8 char) on:

Hi Joe,
very nice results from your SpecLab files!

I easily saw my carriers and the PSK symbols in each of the files= , so there was no need to make use of the pilot. Then in 6 out of 7 files, = I decoded the *OBELIX* message, and tweaked each time offset for best SNR. = Knowing my transmit start time (0.2 s after the hour), I could then derive = that your PC clock had been 2.1 to 2.6 seconds late. Note that this would h= ave been impossible if the signal hadn't shown up the rawsyms plot, whi= ch is why we usually=C2=A0 depend on reliable timing.

Using = the time and frequency information, I calculated theoretical offsets for th= e IW4DXW. who was transmitting 4.9994 Hz below me. Unfortunately Ric's = signal wasn't quite strong enough to produce a plausible decode (perhap= s due to the snow on his antenna).
