HF Radio Propagation Primer by AE4RV
(requires Adobe Flash Player)


Tenth Anniversary! This is one of the first Flash movies I ever created. This is still what I do to pay the bills...

Use this Flash movie to learn how HF or "Short-wave" radio works. Learn about the Ionosphere, Solar Flares, and why radio waves skip or refract off of the different layers of the Ionosphere. Learn how space weather affects radio conditions. This presentation is useful for Ham radio operators, DX'ers and SWL's (short wave listeners), even military ops.

Solar Cycle 24 has its own website!

NEW: Download this presentation as a ZIPPED EXE file (PC).
