Propagation : MUF Indicators
  • Near-Real-Time F2-Layer Critical Frequency Map - This map can be used to determine the frequencies that will always be returned to the Earth. Transmitted frequencies higher than the indicated contours (which are given in MHz) may penetrate the ionosphere, resulting in lost power to space. The map shows the radio auroral zones as green bands near the northern and southern poles.
