Ok i see, it makes no sense that way. The last > 100 transmit hours did not lead to a success... Does the message decode when correcting the phase? I think not. BTW, instead of doubling my antenna current, Mike could build up a 3 axis RX :-) This would give us an average gain of at least 6 dB i think. And we need to learn to predict/estimate the phase, if possible. Where are the propagation experts?! :-) 73, Stefan Am 22.12.2017 17:16, schrieb Paul Nicholson: > > Stefan wrote: > > > f = 17470.1000 Hz > > Start time: 18.Dec.2017 21:30:00 UTC > > Symbol period: 45 s > > Characters: 2 > > CRC bits: 14 > > Coding 16K21A > > > Can you give me a feedback from the last night? > > Now with 4 nights: > > 18/19th Eb/N0 = -4.9 dB, S/N -39.6 dB in 1Hz, phase 110.4 > 19/20th Eb/N0 = -6.5 dB, S/N -41.1 dB in 1Hz, phase 125.6 > 20/21st Eb/N0 = -7.8 dB, S/N -42.4 dB in 1Hz, phase -22.5 > 21/22nd Eb/N0 = -9.4 dB, S/N -44.0 dB in 1Hz, phase 55.6 > > No improvement on the earlier stacking: best is still > 18/19 + 19/20 to give Eb/N0 = -2.7 dB > > This isn't going to work without a repeatable night phase. > > -- > Paul Nicholson > -- >
