Hi Paul and Markus,

Great results! Thanks for the reception and decode.

Well, let's try something for the record list again:

f =3D 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
