Phase variations of 16 kc/s transmissions from Rugby as received in New Zealand

Abstract

The results of approximately one year's measurement of the diurnal phase variation, in New Zealand, of the highly stable 16 kc/s transmission from GBR are given and discussed. If it can be considered that the signal is received by the short great-circle path, the observed phase variations appear to be in accordance with propagation via the TM₀₁-mode which exists between parallel, plane metallic sheets.
