Ground Wave Propagation Ground Wave Propagation
HF radio propagation primer 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
Ionospheric propagation explained
Propagation of waves propagation, radio is all about the transmission of radio waves from place-to-place without wires. Signals travel from the transmitting antenna to the receiving antenna in different ways depending on the frequency used. Some frequencies use the ionosphere to bounce signals around the world while other frequencies can only be used for line-of-sight operations
