↑ HF Propagation Prediction Online

By Doron Tal, 4X4XM

There are various methods to predict HF propagation conditions. For example:

  1. Simulation:
    Online applications employing propagation models can predict propagation conditions, signal quality along specified paths, and offer additional valuable information.
    Software packages predict HF propagation conditions using propagation models, and real-time regional inonospheric conditions.
    See reviews of such packages.
  2. Space weather services provide real-time information on Solar-Space-Terrestrial data, which influence HF propagation conditions. Operators can make informed predictions about global and regional propagation conditions by monitoring these services.
  3. DX Clusters: Data collected from QSO reports is used to display real-time band activity in various parts of the world at certain HF band.

Overall, online HF propagation evalutaions can be made using a combination of the above methods to get the most accurate and up-to-date information.

If you need a short term prediction it is recommended to use MUF 3000 Km Propagation Map.
