Optimal propagation conditions of multiple round-the-world signals
Abstract
Observations of multiple round-the-world signals were made during 1970-1983 at the Khabarovsk station at operating frequencies of 11-21 MHz under conditions where the transmitter was in proximity to the receiver and large-multiplicity signals were recorded in reception time periods of signals of lesser multiplicity. It is shown that, in most cases, the optimal propagation conditions corresponded to small slopes of the ionosphere in the vicinity of the receiver in conjunction with slopes of different sign where the propagation path crossed the terminator.
