↑ Radio Propagation Forecast

This page is part of the project "Understanding HF Propagation"
by Doron Tal, 4X4XM

Radio propagation forecasts enable radio operators to optimize communication by selecting the best frequencies and times for making contacts. Researchers assess propagation conditions globally and regionally:

  1. Global propagation conditions refer to the overall state of the ionosphere and its impact on radio wave transmission across our planet. These conditions are influenced by solar activity, geomagnetic storms, and other large-scale phenomena.
  2. Regional propagation conditions, on the other hand, focus on specific geographic areas.

Examples for global and regional radio propagation forecasts:

  2. The MUF 3000 Km Map by Andrew, KC2G illustrates the current regional propagation conditions:

Additionally, knowledge of the solar indices and the space weather indices may provide radio operators with a broader understanding of the state of the HF bands. See dynamic collection of propagation information gathered from many different sources by Doug Brandon, N6RT.
