Tropospheric Propagation Forecast Beyond the Horizon

WebBig red blotches are usually good signs of Tropo openings. If you're on the edge of a blob, you should be able to hear VHF DX towards the center of the blob. Alternatively, DxMaps shows realtime spotted QSOs, but it's not nearly as active or indicative of sudden openings. 4.

Extended "tropo ducting" represents a super refraction in which the height and dielectric characteristics of the layer are so important at large scale that it offers true airways to VHF waves. These openings occur more often on 2 m than on 6 m and generally signals tend to be ... pokecenter in minecraft
