Observations of the multiple frequency omega transmissions

F. Kenneth Steele; A. H. Diede

Abstract: Observations of 9.2, 11. 2, 12.2, 13.6, 15.2, and 17.2 kHz Omega signals radiated from Forestport, New York, and from Haiku, Hawaii, as received at Boulder, Colo., and at Anchorage, Alaska, are presented. Phase and amplitude data collected at these frequencies are discussed briefly in connection with diurnal and sunrise variations. Comparisons are made between theoretical and experimentally deduced differences in wavelengths, attenuation rates, and transmission losses.
