Problems of Transition to Single-Sideband Operation

Single-sideband operation, in its most advanced forms, is not compatible with transmitting and receiving equipment presently in use for voice circuits throughout the world. Changing to a new system of modulation presents problems during the transition period. These problems include questions of technical standards, frequency allocation, compromise modulation systems to permit compatible communication with unconverted stations, and in changes in operating customs and procedures that may become desirable as a result of the other modifications. Some of these problems are outlined and discussed in this paper.
