Portfolio: HF Radio Propagation Primer   << Previous | Portfolio | Next >>
  I wrote and developed this Flash piece in 1999 to explain the properties of short-wave radio propagation. This presentation explains how radio waves can travel all over the world without a satellite. Recently I was asked for and granted permission to use this piece by a radio instructor who works for the US Navy. It is also used as part of an Amateur Radio display in the Swiss Museum of Transportation and Technology.
