...the message was running on the 20th, 22th and 23th.
Today i made a mistake in the SpecLab settings which unfortunetely
affectet the transmission.
I watched the alternating colours (due to the PSK) and saw that it
doesn't switch the phase as expected. Then i quickly restartet SpecLab,
it was bit chaotic but now it should work again. Since the symbol
length is 3 minutes it was easy to delete the first 11 symbols and
start this special file at 16:33:00 UTC. All in all just the first 8
symbols are affected. 2 of them were transmitted correctly
(productive), 2 of them have opposite phase (destructive) and 4 were
not transmitted (not really neutral but not so dramatic).
Fortunately the transmission takes 12 hours, so 24 minutes is just 3.3
% or -0.15 dB.
The transmimission should now continue as expected.
Just a note for those who follow it...
