Bob G6CKK / VE3IDZ is using two Zaktech WSPR transmitters to watch live propagation on 40m and 20m.
The page shows recent WSPR reports on a live map, with line colour showing signal strength and endpoint colour showing the band.
The system updates automatically every 4 to 5 minutes.
This is intended as a simple live guide for activators and radio operators, not a guaranteed propagation forecast.
