Exploring WSPR Weak Signal Propagation Reporter (WSPR - pronounced 'whisper') is a super efficient digital mode that allows milliwatt radio signals to span paths on frequencies you wouldn't think possible. It achieves this by being both narrow band and ultra-slow. In fact it's so slow it takes two minutes to send a few characters and it's a beaconing rather than a conversation mode. These videos demonstrate various aspects of WSPR: transmitting, receiving, construction, portable and more.
