Abstract:

Plots of data are presented that enable prediction of maximum hf communication coverage between ships in the areas of the Philippine Islands, Gibralter, and Iceland-U. K. The data show the manner in which the signal-to-noise ratio varies with time for extremes of sunspot number and season. Short-term effects and propagation via mixed modes are not considered. Author
