Of cours= e Eb/N0 is invalid due to plenty symbols missed.

Hello Markus,

Such a small drift, could it be propagation? It was during the onset of the night.

I played a bit further and changed the frequency offset from 41.993 Hz to 41.9931 Hz and got a 0.8 dB better Eb/N0.

Hi Alex, LF,

Also copied R7NT here in Heidelberg. An early decode. First decode from Russia here.
There is an offset of -7 mHz. First i tried 42 Hz offset (offset to 137.5 kHz) and got no decode. It shows how critical the timing is. But it also shows how helpful Markus' 'show_rawsyms3b' feature is. =
