Good decode of your 20170222 transmission in Warsaw (the decoded message sent off-list so i don't spoil anyone's fun).

found rank 0 ber 2.5223e-01 Eb/N0 8.2 M -1.913291931e+01 [XXXXXXXX] ps [  0    
0    0    0    0]
carrier phase: 0.7
carrier Eb/N0: 9.0
carrier S/N: 25.57 dB in 24.8 uHz
elapsed 41

Eb/N0 is 8.2 (compared to 5.5 for the 2-character message with similar transmission length some time ago), i hope this due to the antenna work i've done.

...delayed by 30 minutes :-(
Start time: 22.Feb.2017   18:30:00 UTC

11h 12min is about the night time between Heidelberg and Moscow now. The delay 
and the later end of
the transmission may already fall into the daytime in Moscow, which may cost 
the dcode? It's always
critical, hence exciting :-)
