↑ Tools for Forecasting and Predicting
HF Propagation Conditions for Radio Amateurs
This page is part of the project "Understanding HF Propagation"
by Doron Tal, 4X4XM

Here are several tools available to help radio amateurs plan their radio operations effectively.
The terms forecasting and prediction differ primarily in their time frames and methodologies.

  • Forecasting: Short-term estimations based on real-time data (e.g., "Conditions will improve in the next hour").
  • Prediction: Long-term projections using historical trends (e.g., "Better 40-meter conditions expected next month").

    Forecasting Tools

  1. PSKReporter: A tool that allows radio amateurs to track and report propagation conditions, providing a global map of signal paths.
  2.  
  3. WSPRnet—Weak Signal Propagation Reporter: A tool for reporting and tracking propagation conditions globally, useful for identifying propagation paths and monitoring changes.
  4.  
  5. Real-time data that can be used to estimate the current propagation conditions:

    1. Current Ham Activity
      DXview
    2. Recent HF Bands Conditions
      Animated 3000km
    3. Predicted HF Bands Conditions

    Prediction Tools

  1. VOACAP (Voice of America Coverage Analysis Program): A free and popular program that predicts radio propagation conditions between two locations for a specific time of day and frequency, providing information on the best times and frequencies for long-distance communication.
  2.  
  3. HFTA (High Frequency Terrain Analysis): A software tool that models antenna performance based on terrain and other factors, helping to predict signal strength and coverage area.
  4.  
  5. DX Toolbox A software tool offering features like propagation predictions, grayline mapping, and solar weather tracking.
