WSPR (usually pronounced "whisper") is a software application that uses the transmission mode MEPT-JT (Manned Experimental Propagation Transmitter - Joe Taylor).
In MEPT transmissions, the radio becomes a beacon that transmits for just under 2 minutes, transmitting callsign, locator and power information. Modulation is by narrow band FSK.
