HF Propagation Prediction

HF (High Frequency) propagation prediction is the process of forecasting the behavior of radio waves in the ionosphere, which can affect long-distance communication on the HF bands.

The ionosphere is a region of the Earth's atmosphere that refracts radio waves back to the ground, allowing them to travel great distances. However, the ionosphere is dynamic and can be influenced by various factors, such as solar activity and weather conditions.

Accurate HF propagation prediction is essential for radio operators. Several tools and techniques are used for HF propagation predictions, including computer models, empirical algorithms, and real-time monitoring of ionospheric conditions.

The project "Understanding HF Propagation" focuses on near-real-time indicators and explains what they mean.
