I think it is a Geschenk for both of us. We are a good team i find. I guess that's the longest message (by amateurs) on VLF so far. When starting on 46 km in summer, i didn't expect that we will manage such good results there, so i'm quite satisfied. There is still some confusion about unstable colours (-> phase) on my local monitors, although things should works fine. There is no frequency offset or drift, so the SpecLabs sample rate correction must work. However the colours looks like a nice rainbow :-) On the other side i can decode my EbNaut messages with 0 errors. Strange. That was the reason why i stopped the DEC.24th transmission. But maybe this has not been necessary. Anyway, now we are here :-) It is now time for me to leave the 46 km band (again) and i will move to the 58 km band. I will start a new thread... This thread has started on May, 3th, 2016 :-) 73, Stefan Am 25.12.2016 17:35, schrieb Paul Nicholson: > > Ich habe ein kleines Weihnachtsgeschenk für Stefan! > > The 75 character message received at 6470 Hz: > > "HABE DEN MUT DICH DEINES EIGENEN VERSTANDES ZU BEDIENEN > - IMMANUEL KANT -" > > by coherent summing of 7 daily transmissions. > > Eb/N0 = -0.2 dB, BER 32.44%, constant reference phase. > > List decoding rank: 1987053. > > S/N: 26.14 dB in 36.9 uHz, -52.2dB in 2.5kHz. > > Day Phase Eb/N0 > 2016-12-18 41.2 -5.5 > 2016-12-19 47.2 -10.1 > 2016-12-20 38.0 -8.2 > 2016-12-21 40.5 -10.1 > 2016-12-22 48.0 -11.0 > 2016-12-23 50.9 -8.8 > 2016-12-24 42.9 -12.2 (not used, skipped) > 2016-12-25 46.6 -7.1 > > -- > Paul Nicholson > -- >
