WSPR Analytics

WSPR (“whisper”) is a beacon mode where stations send tiny, low-power signals and thousands of receivers around the world automatically report what they hear. Every report goes into one giant public database. Type a callsign below to see where that station’s signal has been heard, how far it reached on each band, and the best times of day to be on the air.

About the data: spots come from WSPRnet through the free wspr.live database, usually within a few minutes. Up to 5,000 of the most recent spots are shown. Times are Eastern. Want to start? WSPR runs in the free WSJT-X program on almost any HF radio, and many hams use tiny stand-alone beacons like the QRP Labs U3S or a Raspberry Pi.
