↑ What is HF Radio Propagation Prediction?

By Doron Tal, 4X4XM

HF radio propagation prediction is the process of using computer models to predict the behavior of High-Frequency (HF) radio waves as they travel through the Earth's ionosphere. High-frequency radio waves can be used for long-distance communication, but their propagation is heavily influenced by ionospheric electron density and geomagnetic disturbances caused by space weather conditions caused by solar activity.

HF radio propagation prediction models consider a number of factors, including Maximum Usable Frequency (MUF), receiver and transmitter location. These predictions can help radio operators and other HF radio users plan their communication activities more effectively.

Real-time MUF measurements from ionosondes provide critical information for HF radio propagation prediction models, allowing them to more precisely estimate the frequency range over which a radio signal is likely to be effective.
