Reduction of Interference in Broadcast Reception

The factors in station interference with broadcast reception, namely, signal field strength, receiver selectivity, and psychological reactions of the listeners, are analyzed. Statistical data correlating these factors with interference complaints from listeners in the vicinity of the 50-kilowatt broadcasting transmitter at Bound Brook, New Jersey (WJZ), are then presented, these data being the results of a survey by a special interference reduction service. The clearing-up of the complaints by this service, using simple methods which are described, indicates the feasibility of high-power broadcasting stations, as well as the necessity for them because of the requirement of reliable broadcasting service over large areas.
