Radio Communication and Magnetic Disturbances

Abstract

LOOKING through the wireless data of Sir Douglas Mawson's Australasian Antarctic Expedition which has come into my hands through the untimely death of Dr. Chree, I have found a copy of the Australian Monthly Weather Report, vol. 4, No. 9. This contains Mr. F. J. Henderson's analysis of the working of the Macquarie Island station during 1914 and 1915 in the form of a statement of the dates on which the receipt of wireless signals was difficult or impossible, apparently excluding the days on which atmospherics were serious enough to cause the trouble. The stations with which Macquarie Island was generally in communication were Hobart, Wellington, and The Bluff.
