HF propagation map
Real-time HF propagation, drawn from WSPR reception spots via wspr.live. Every line is a confirmed radio path between two grid squares in the last few minutes — an empirical view of which amateur bands are open, where, right now. Filter by band and switch between flat map and 3D globe.
Active paths — last 10 minutes
