Abstract : In the period from September to December 1967, the newest of the very-low-frequency (VLF) transmitting stations operated by the Navy, NWC, at North West Cape, Australia, had scheduled transmissions on six different frequencies in the VLF band. In order to obtain information on propagation paths not previously investigated, the Naval Research Laboratory installed instrumentation to collect data at selected sites in Japan, Madagascar, and Bahrain Island. Transmissions were recorded continuously for a three-month period. Examination of the data allows determination of the optimum frequency for each path investigated. (Author)
