I'm trying another 8 character message, just to get a clear decode from Alex. 
Of course all reports are welcome, as usual :-)
The message has started to late again but not as late as the last one, so maybe 
there will be a clear decode. On the other side there
is more QRN now. Some day we will need a tool for stacking/ combining multiple 
wav files under windows! It would make things easy on
that path.


f = 8270.100000 Hz
Start time: Tuesday 07.Mar.2017   22:20:00.3
Symbol period: 30 s
Characters: 8
CRC bits: 16
Coding 16K21A
Duration: 11h, 12m, 0s
Antenna current: 700 mA

Based on the last carrier S/N of Alex' last decode this could be the result:
But some hours will fall into daylight, so it will be quite close to the limit 
again! :-)

73, Stefan
