  • Real-time MUF Propagation Map - qsl. net
    A real-time Maximum Usable Frequency (MUF) map reveals HF propagation conditions in the last 15 minutes
  • MUF (3000km) - kc2g. com
    MUF is the highest frequency that is expected to bounce off of the ionosphere on a path 3000km long So the MUF along a path between two points shows the possibility of long-hop DX between those points on a given band If the MUF is 12MHz, then 30 meters and longer will work, but 20 meters and shorter won't For long multi-hop paths, the worst MUF anywhere on the path is what matters For
