About estimating propagation

Radio Explorer has features for shortwave propagation prediction that can help you in choosing the most reliable frequencies for your reception.

The engine for propagation calculations is the MiniMUF algorithm. It computes the Maximum Usable Frequency (MUF) for a shortwave signal. The MiniMUF algorithm is relatively simple, but effective, and allows to quickly build MUF coverages for large map areas. Please refer to the glossary articles MUF and MiniMUF.

More information is available at the MiniMUF view page.
