Maximum usable frequency (MUF) is the highest radio frequency that supports communication between two points on Earth by reflection from the ionosphere (skywave or skip) at a specified time, independent of transmitter power. The following map visualizes the current ionospheric conditions that affect global HF radio propagation, aiding radio operators in assessing optimal frequencies and communication paths.
