Shortwave Radiograms are digital transmissions that can be decoded all over the world using an SDR receiver and Digimode software. Shortwave Radiogram transmits digital text and images on an analogue shortwave broadcast transmitter. The program is produced and presented by Dr. Kim Andrew Elliott.
Anyone interested on this kind of technology can experiment and receive the radiograms on your computer…
Just check the website for all the info…!
