Some of the popular newer modes are Binary Phase Shift Keying (BPSK), Weak Signal Propagation Reporter (WSPR), and the weak signal digital modes JT65/9. Some are as simple as Morse code (CW) or Radio-teletype (RTTY), while others are more sophisticated such as AMTOR or SITOR which are similar to RTTY. In this article, I will show you how to use a low cost ($62) shortwave radio to get you started in this exciting hobby.ĭata transmissions vary in complexity and contain a wide variety of information.
If you are connected to the Internet, your radio receptions can be reported to websites like, , and others where they will be displayed on a world map such as PSK Reporter as shown in the lead photo.
As amazing as it seems, many of these data signals can be picked up and decoded at home using just a low cost shortwave receiver, your PC, and some specialized software. Digging a bit deeper, there is another world of shortwave radio that does not use conventional sounds. Listening to shortwave radio is very interesting, and filled with the voices and music of far-off lands.
