From now on i'm trying to pass 12 characters over to near Moscow, despite the failed decode of the 3 char message.
Details:

f = 5170.1000 Hz
Start time: 29.Dec.2017  15:00:00 UTC
Symbol period: 30 s
Characters: 12
CRC bits: 20
Coding 16K21A
Duration: 14:56 [hh:mm]
Antenna current: 300 mA

A challenge for Jacek also, i think.
Maybe even for Riccardo with his new setup?
