Typically 100 pages, it includes a mixture of news, theory, construction and technical articles of interest to the amateur radio community.

In July 1925, it was decided by members of the Society's Transmitting and Receiving (T & R) Section to produce its own monthly publication "written by and for the radio amateur".

The remaining pages are devoted to a number of regular columns covering topics such as low frequency, amateur television, VHF/UHF, electromagnetic compatibility, radio propagation, contesting, and many other subjects.

There are two or three in-depth technical articles per month, plus reviews of new equipment and other features which relate to amateur radio as a whole.

The early history of RadCom and the Radio Society of Great Britain is described in World At Their Fingertips by John Clarricoats, G6CL, ISBN 0-900612-09-6
