SW Radiogram, August 5, 2017

Today at 16:00 UTC I received, once again, this weekend's Shortwave Radiogram on 9400 kHz AM. The transmission by Radio Miami International used the transmitters of Space Line in Bulgaria.

The digital modes transmitted in the TX audio were MFSK32 and MFSK16, and included 5 images. 

I used my Icom IC-706 MkII with a dipole antenna tuned for 3.5 and 7.0 MHz and a MFJ-969 antenna tuner. Decoding software is FL-digi 4.0.9.8 under Windows XP. 

Text reception was good, but not 100%, with occasional garbled charaters due to QRM. Mode switching between MFSK32/16 was done automatically.

The images were also received successfully with some deterioration due to co-channel voice interference.

I sent an email with my reception reports to radiogram@verizon.net  right after the transmission.
