REPORT OF TELECOMMUNICATION FOR THE JAPANESE ANTARCTIC RESEARCH EXPEDITION WINTERING TEAM, 1959

Abstract

Syowa Base Radio was reopened in Feb. 1959. 1. Radio Installation at Syowa Base The installation at Syowa Base was composed of two transmitters. The first set was a 1 KW HF A1 Transmitter. This set was associated with the photo-transmitting attachment later. The second set was a 400 Watt HF A1 A3 Transmitter. This set was used for communication between stations in Antarctica. Small power portable A1 A3 Transceivers were used also by the field parties. 2. Telegraph communication between Antarctica and Japan The official telegrams were exchanged between Syowa Base and Japan, via Choshi radio station. About 340 thousands letters were transmitted and 94 thousands letters were received during 1959. 3. Radio-photograph transmitting from Syowa Base Radio-photographs were transmitted from Syowa Base in and after August 1959. For this purpose the 1 KW main transmitter was associated with the photo-transmitting equipment. 4. Telegraph communication between stations in Antarctica Syowa Base Radio established contact with Mawson, Durville, Halley Bay, King Baudouin, Davis, McMurdo, Mirny, any Norway station, and many messages were exchanged between those stations and even other stations through those stations. Two thousand messages were handled by Syowa Base Radio during 1959. Meteorological data were transmitted to Mawson twice a day, and forwarded to Meteo-Bureau in Australia. Syowa Base Radio handled also auroral, cosmic-ray, geomagnetic, and seismic data, especially seismic data which were exchanged between many stations in Antarctica.
