Hi Joe,

I can report a couple of decodes from your 3:45 and 4:00 UT sequences last night (Aug 18). Timing and frequency were good, and the signal was well visible on the grabber and in the phase plots. But still the decodes came out with no more than 0 and 2.4 dB Eb/N0, so maybe something in my RX setup is still not optimal.

All the best,
Markus (DF6NM)

Hi Stefan,

Perhaps I should QSY back to 137.477 again! On 777 tonight and will
try 477 tomorrow if that's OK. How big are the text files?

I use your grabber to check my sigs. Thanks for this service!
