東京-昭和基地間の短波伝ぱん特性
Measurements of the field intensity of 6055 KHz (NSB, Nippon Short Wave Broadcasting), 9595 KHz (NSB) and 15300 KHz (NHK, Radio Japan) were made at Syowa Station in Antarctica, from April 1966 to January 1967. Results were compared with the calculated values by the two methods developed by K. MIYA a...
