This page displays live HF propagation conditions for the FM18 and FM19 grid squares (DC Metro / NASA Goddard area), updated every 6 minutes using data from the WSPR network.

WSPR (Weak Signal Propagation Reporter) is an automated beacon system where low-power transmitters send a short digital signal and receiving stations around the world log what they hear. The spots listed here are filtered to show only paths with strong enough signal levels that a real SSB conversation would be possible using 100W and a dipole — marginal and weak paths are excluded.

Use the band tabs to see which HF bands are open right now. The Transmitting section shows local stations being heard by the world. The Receiving section shows stations that local receivers are hearing from around the globe.

Data is sourced from wspr.live and refreshed every 6 minutes. Only spots from the last 2 hours are shown.
