↑ Forecasting propagation tools
for radio amateurs

By Doron Tal, 4X4XM

There are several forecasting tools available for radio amateurs that can help predict propagation conditions and plan their radio operations accordingly. Here are a few options:

  1. VOACAP (Voice of America Coverage Analysis Program): VOACAP is a free and popular program that allows radio amateurs to predict radio propagation conditions between two locations for a specific time of day and frequency. It can provide information on the best times and frequencies for long-distance communication.
  2. HFTA (High Frequency Terrain Analysis): HFTA is a software tool that allows radio amateurs to model antenna performance based on terrain and other factors. It can help predict signal strength and coverage area.
  3. DX Toolbox is a software tool that provides a range of features for radio amateurs, including propagation forecasting, grayline mapping, and solar weather tracking.
  4. WSPRnet: WSPR (Weak Signal Propagation Reporter) is a tool that allows radio amateurs to report and track propagation conditions on a global map. It can be used to identify propagation paths and monitor changes in propagation conditions.
  5. Space Weather Prediction Center (SWPC) provides real-time information on solar weather and its potential impact on radio communications. This can be helpful in predicting propagation conditions and identifying the best times and frequencies for communication.
These are just a few examples of the many forecasting tools available to radio amateurs. It's important to choose a tool that meets your specific needs and preferences.
