SW Radiogram over WRMI 7780 kHz





Tonight I managed to receive the Shortwave Radiogram digital transmission over WRMI - Radio Miami International on 7780 kHz using my Perseus SDR receiver and fldigi 4.0.17 by W1HKJ. The antenna is a trap dipole for the 40m and 80m bands.




The transmission began on July 22, 2018 at 22:30 UTC with a brief waterfall image and was followed by approximately 30 minutes of MFSK32 and MFSK64 text and images.

MFSK text reception was 100% error-free, while images were degraded by the high level of noise which affects reception at my location.
