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 pictured at
