Abstract
The possible limitation in the number of long distance radio stations simultaneously in operation is considered. It is shown how high-speed transmission, improved directional selectivity, and better frequency selectivity would greatly increase the number of feasible co-existent stations, The utilization of a wave length band as a result of high-speed transmission is discussed in connection with frequency selectivity. The 200-kilowatt alternator station at New Brunswick is described, special mention being made of the constant speed regulation system for the induction motor drive, the functioning of the magnetic amplifier, and the operation of the multiple antenna. In this latter connection, the possibilities of effective directional radiation are considered.
