PHASE STABILITY MEASUREMENTS OF 18.6-KC RADIO TRANSMISSIONS.

Abstract

Measurements were made of the arrival time of 18.6 kc signals over a north-to-south propagation path by means of phase comparison. The variability of the transmission time during both daytime and nighttime was measured, as well as the diurnal changes. The results were consistent with those reported by other investigators. The diurnal rate of change of transmission time appears to be related to the solar illumination of the total propagation path. (Author)
