Abstract
AT the inaugural meeting on October 10 of the Radio Section of the Institution of Electrical Engineers, the chairman for the present session, Mr. A. H. Mumford, gave an address in which he reviewed some of the more general communication developments carried out by the Post Office Engineering Department during the past few years. These developments covered three main fields: first, the extension and improvement of the facilities for world-wide telegraphic communication on a low frequency ; secondly, the study and improvement of long-distance high-frequency telephone and telegraph circuits ; and thirdly, the extension of very-high frequency radio links for multi-channel communication over short distances.
