Abstract : Some of the problems associated with transequatorial radio communication between Antarctica and the Northern Hemisphere at 22.6 MHz are discussed. The information is based on experience with US equipment at Byrd station. The field intensity of a 22.6 MHz radio signal received from Pearl Harbor at the Byrd station in the Antarctica on the 25th and 26 of March, 1961 is plotted as a function of time. The height of the earth's shadow is also plotted for 30-minute intervals over the radio line connecting Byrd and Pearl Harbor. The author concludes that when one is located in the Antarctica it is possible to select a series of 24-hour radio stations situated above the equator to study the propagation of short waves throughout the tropical region. Of particular interest would be the investigation of short wave radio propagation during total eclipse. If such transmission were possible it would indicate that a High F sub 2 ionosphere layer is present in the tropics and that it would therefore, be possible to have short wave communication between the Northern Hemisphere and Antarctica.
