Reports of special committees

Abstract

Time‐Signal Service (H. E. McComb, Chairman)—The Committee reported that a large number of users of United States Navy Department time‐signals in the fields of applied geophysics, geodesy, and seismology have supplied information relative to the extent of the use of these signals. The general character and number of these communications prove that the time‐signals are used in a wide variety of scientific investigations. The Committee will supply detailed information on specific signals in its final report to the Union. Several users have reported serious difficulties in the reception of the 9425‐kilocycle signal due to interference from foreign stations. Others have suggested the desirability of having additional signals on some of the standard frequencies now on the schedule.
