Maintenance of Broadcast Operations in Wartime

This paper deals with the technical measures which have been taken in Canada by the Canadian Broadcasting Corporation to meet the daily increasing difficulties of maintenance of broadcast operations in war time. After a brief description of the facilities involved in these plans the paper outlines the steps that have been taken in the physical protection and guarding of broadcast plants. The problem of conservation of equipment in the face of acute shortages is then discussed with the measures that have been applied to prolong the life of tubes, microphones, and other equipment. In treating the final aspect of the problem, that is, the maintenance or resumption of essential operations after destruction of regular facilities, the paper describes the setting up of emergency and stand-by facilities such as secondary control centers, stand-by transmitters, frequency-modulation links, and other equipment designed to insure continuity of service.
