Too late for 20:00, nil of 21:30, but then a good one at 21:00, +1.3 dB, 1.2s offset.

Andy your spectrogram nicely shows the 0.5 Hz wide "noise hump" from the modulated transmission, so the signal is still relatively strong for you.

All info on the decodes will be in the xxx-log.txt file.

 

BTW Under Windows 8 or 10, the show_rawsyms3a utility sometimes froze on exit. Fixed with version 3b in http://df6nm.bplaced.net/VLF/fec_tests/df6nm_ebnaut_utilities.zip

 

Good luck and have fun,

Best decode here is at T offset +0.8 

Eb/N0=5.4 phase 150  150  180  180 

 

I run 10 copies of the decoder in steps of 0.2 seconds 

and grep the log files.
