SW Radiogram, July 29, 2017

Today I received this weekend's Shortwave Radiogram on 9400 kHz AM. The transmission by Radio Miami International was using the transmitters of Space Line in Bulgaria.

The digital modes transmitted in the TX audio were MFSK32 and Olivia 64/2k, and included 5 images. 

I used my Icom IC-706 with a dipole antenna tuned for 3.5 and 7.0 MHz and a MFJ-969 antenna tuner. Decoding software is FL-digi 4.0.4 under Windows XP. 

Text reception was 100% without errors and mode switching between MFSK and Olivia was done automatically. 

Iran's Simorgh rocket...

China Unicom's company logo...

Radio Prague logo...

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.
