MUF Propagation Map

The maximum usable frequency (MUF) is the highest frequency reflected from the ionosphere, effectively predicting propagation conditions between specific locations at a given time. This map visualizes the current ionospheric conditions that affect global HF radio propagation, aiding radio operators in assessing optimal frequencies and communication paths.
