WSPR implements a protocol designed for probing potential propagation paths with low-power transmissions. Normal transmissions carry a station’s callsign, Maidenhead grid locator, and transmitter power in dBm. The program can decode signals with S/N as low as -28 dB in a 2500 Hz bandwidth. Stations with internet access can automatically upload their reception reports to a central database called WSPRnet, which includes a mapping facility. To see a live version of the map, click here.
