VHF APRS Propagation Map

VHF – Based on realtime APRS reports. This map shows real-time radio propagation from stations operated near 144 MHz. It uses data gathered by Automatic Packet Reporting System-Internet Service (APRS-IS) from packet stations in the amateur radio service.

The map shows activity from the past hour. Paths are smoothed to create a color-coded footprint indicating the distance VHF signals are likely to be traveling.
