Content preview: Thanks Paul, Oh oh oh it is not easy at all! The stacking works with limited improvement over that path. Wonder if 8270 Hz would work better... The next transmission is already running.. One could correct the phase and stack then. But this would not be legitimately because the message is unknown to the receiving station, so it can't know the phase before the decode happens.

I'm missing the really low frequencies :-) 73, Stefan Am 15.12.2017 19:32, schrieb Paul Nicholson: > > Still not there yet. > > 2017-12-10/11 Eb/N0 = -13.1 dB (very noisy night) > 2017-12-11/12 Eb/N0 = -6.3 dB, phase 125.3 > 2017-12-12/13 Eb/N0 = -6.8 dB, phase 143.2 > 2017-12-13/14 Eb/N0 = -19.6 dB > 2017-12-14/15 Eb/N0 = -6.0 dB, phase 68.8 > > Stacking > > 11/12 + 12/13 gives Eb/N0 = -3.6 dB. > 11/12 + 12/13 + 14/15 gives Eb/N0 = -3.0 dB. > > Good signal last night but the phase was a bit > different. > > -- > Paul Nicholson > -- >
