N6RT Propagation Information

This page contains a dynamic collection of propagation information gathered from many different sources. This data is extremely useful for ham radio operators and shortwave listeners to help determine whether or not long distance radio communications are possible.

Propagation Studies Committee of the Radio Society of Great Britain

The Propagation Studies Committee of the Radio Society of Great Britain stemmed from a suggestion made in 1957 by Dr. Smith-Rose, then Director of the Radio Research Station, Slough, and later to become a President of the RSGB, that a small committee should be formed to attempt to correlate radio amateur observations with 'auroral, ionospheric or meteorological conditions'. This led to the formation of the Scientific Studies Committee, which was re-named the Propagation Studies Committee in 1976.
