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: <STX> WINTER SWL FEST The forums for the Winter SWL Fest, 14-15 March near Philadelphia, have been scheduled. Topics include... Internet radio Radio's future Scanners Archiving shortwave broadcasts Ionosounders North Korean media Ham radio tools for SWLs Digital radio Loop antennas Remote receivers I will be there to demonstrate VOA Radiogram and the decoding of text and images via shortwave broadcast.
