The KBC Radiogram on 7375 kHz from 01:30 UTC (2:30 CET - Central 
European Time) I had recorded with the recording scheduler of HDSDR and 
just decoded with STUDIO1 + FLDIGI.
The reception here was not very good O = 2-3. It was a mixture of ground 
wave and backscatter. Thus, the decoding rate of MFSK64 was only 60%, on 
the picture was nothing to see.
I think even in North America, the reception situation is critical and 
MFSK-64 is too exaggerated.
Effective here would be a two-track transmission simultaneously with 
image / text in MFSK16 , at most in MFSK32.

The reconstructed contet of the message was:
