Radio Wave Propagation Resources

Radio propagation explains the behavior of electromagnetic waves when transmitted, or propagated from one point on to another through a non-conductive medium like air or space.

Amateur Radio Propagation Studies

This site primarily addresses phenomena in the radio world above 50 MHz including long-distance forward scattering by sporadic E layers in the ionosphere, backscatter of radiowaves aligned to the Earth magnetic field (radio Aurora and its mid-latitude companion, i.e. FAI), tropospheric beyond-the-horizon radio propagation, meteor scatter communication, intercontinental VHF/UHF/SHF communication by using the scattering properties of the lunar surface, transequatorial VHF propagation and many other fascinating aspects of radiowave propagation on very high frequencies, by Volker Grassmann.
