THE present War has been accompanied by great advances in the application of radio technique to communications and other purposes, and much thought is already being given to the conversion of the results of this work to peace-time conditions. Among the major problems of a post-war world will be the allocation of different portions of the radio-frequency spectrum among the various interests involved, and the consideration of the trend of broadcasting with both amplitude and frequency modulation, and of television. In the United States of America, the body responsible for frequency allocation and for controlling the standards used in the systems developed for the various radio services is the Federal Communications Commission; and in November 1942 the chairman of the Commission, Mr. J. L. Fly, suggested that an organization representative of the radio industry and of the personnel involved therein might be set up to consider the technical requirements of the future in the field of radio. Accordingly, a Radio Technical Planning Board (R.T.P.B.) was set up during 1943; and an account of the organization and work of this body to date has been given by its chairman, Dr. W. R. G. Baker, in the June issue of the General Electric Review (U.S.A.).
