Abstract :
In this paper, the author summarizes the growth in the number of complaints of radio interference, and outlines typical causes in the various fields of utilization of electricity with the aim of indicating the relative part chargeable to power companies. The radio industry itself, moveable or extraneous sources, signal lines and equipment, power lines themselves, connected power company equipment, connected commercial loads, household circuits and appliances, are dismissed and location methods described, with mitigation measures which have been found effective. In its preparation, the writer has had at hand reports of member companies of the Pacific Coast Electrical Association (the Pacific Coast Section of the N. E. L. A.) as chairman of the Inductive Coordination Committee, and the results of tests conducted by the General Electric Company on various pieces of equipment. He has also had the benefit of committee discussion, both local and national, and correspondence and conferences with other men engaged in the common problem from coast to coast.
