The Ninth Plenary Assembly of the CCIR

The International Radio Consultative Committee held its Ninth Plenary Assembly in Los Angeles, California, April 2 through 29, 1959. The CCIR studies the technical factors affecting international radio telecommunications and makes recommendations to administrations which are of importance in the international allocation and usage of the radio spectrum. These studies are made by fourteen Study Groups, each dealing with certain aspects of international telecommunication. At the Los Angeles meeting, the technical aspects of relatively new techniques for conservation of spectrum space were considered. Transmission and receiving standards, propagation characteristics, monitoring methods, modulation techniques including single sideband and stereo sound broadcasting, and the new international aspects of telecommunication with and between space vehicles were among the many topics considered by the Assembly.
