Hi Paul and Markus,
Great results! Thanks for the reception and decode.
Well, let's try something for the record list again:
f = 8270.100000 Hz
Start time: 24.May.2017 20:00:00 UTC
Symbol period: 10 s
Characters: 160 ( 1 SMS length :-) )
CRC bits: 10
Coding 8K21A
Duration: 22h
Antenna current: 700 mA
It is a challenge for the DL0AO cardioidal antenna looking towards
the west :-)
73, Stefan
