This map shows real-time radio propagation from stations operating on 11 bands between 1.8 and 54 MHz in the amateur radio service. The display shows worldwide activity from the last 15 minutes and is automatically updated about every minute.
The areas noted in the forecast have the necessary atmospheric conditions to produce tropospheric bending of VHF, UHF and/or microwave radio waves. Tropospheric bending extends the range of radio & TV stations well beyond their normal limit and thus increases interference amongst stations as well.
NGØE's VHF Propagation Map displays current VHF band openings during the past hour. It uses data gathered by APRS-IS. The map is created using lat/long info, and hops from node to node that data travels. By correlating hops with the position at each end of the hop, distances can be inferred.
