Band/Frequency Colour Key:
The map above was generated using G7RAU’s Live MUF application. The map uses Great Circle projection centred on the UK. It’s automatically refreshed approximately once per minute.
Radio propagation is reported by amateur radio operators via the DX Cluster network. The Live MUF* application plots the path on the map with the colour indicating the frequency of transmission according tho the colour key.
The normal pattern is for the higher frequencies (above 7 MHz) to be active during daylight, and lower frequencies to be active during the night. Weekends tend to be a lot more active, expecially contest weekends where thousands of amateur operators chase contacts across the globe. The last 100 contacts reported on the DX Cluster can be seen here.
Contact paths remain visible on the map for 15 minutes before being erased.
