What is WSPR mode?
WSPR (pronounced “whisper”) stands for “Weak Signal Propagation Reporter”. It is a protocol, implemented in a computer program, used for weak-signal radio communication between amateur radio operators. The program can decode signals with a signal-to-noise ratio as low as −28 dB in a 2500 Hz bandwidth.
