Do you have phase informations for each day too? It was interesting to see the daily phase variations during our stacking attempts in last winter, it was the 'TEST' message from 11th to 17th November. BTW if we manage to get a decode, then it will be the (new) lowest frequency where amateurs managed to send a message from DL to UK, i.e. an international one way contact! Yesterday i saw that it will be a good day (low QRN), today looks even better, so far. 73, Stefan Am 29.08.2017 23:34, schrieb Paul Nicholson: > > Still no decode, not even with known phase. > > Daily Eb/N0: > > 23rd -6.2 dB > 24th -16.8 dB > 25th -9.2 dB > 26th -10.3 dB > 27th -9.8 dB > 28th -15.8 dB > 29th -8.0 dB > > Combined -2.5 dB leaving out 24th and 28th. > > > If the message would be unknown, could you still fin out that > > it is better to leave the 24th out, just by checking the noise > > background relative to the other days or the days where i sent > > the carrier? > > Yes I've done that in previous tests, dropping out days with a > high background.
