AN ANALYSIS OF THE MARITIME HIGH-FREQUENCY SINGLE-SIDEBAND VOICE COMMUNICATION SYSTEM FOR THE NORTH ATLANTIC AND THE SOUTH PACIFIC. VOLUME I

The report is a frequency trade-off study for both the North Atlantic region and the South Pacific region for the world-wide HF voice communication system. A complement of five shore stations for the Atlantic region, six for the Pacific region, and six frequencies (4, 6, 8, 12, 16, and 22 MHz) are considered. Maps of circuit reliabilities and tables of areas of coverage are produced for two each of seasonal, diurnal, and solar activity conditions. Based on these analyses, the 'best' groups of two, three, and four frequencies are identified. The Atlantic region and the Pacific region are considered independently.
