Wireless Hill Radio Station
Headed by meteorologist George Ainsworth, the radio station was established as part of the 1911-1914 Australasian Antarctic Expedition led by Douglas Mawson in order to provide a radio link between the expedition’s main Antarctic base at Cape Denison, Commonwealth Bay, and Hobart, Tasmania. It comprised a radio shack, an engine room and transmission masts erected at the top of the hill. The equipment used was German-made Telefunken 1.5 kW spark transmitters, with power for radio transmission coming from a De Dion-Bouton engine.
The expedition telegraphists on Macquarie Island, Arthur Sawyer and Charles Sandell, used morse code operated on high frequency. The first transmission of the station was made to another receiver on the island on 17 January 1912. The first communication between the island and the outside world took place on 13 February 1912, with Sydney radio and with shipping. The station subsequently sent daily weather reports to Wellington, New Zealand. Communication with Commonwealth Bay was finally established in April 1913. In 1913 control of the station was handed over to the Australian Meteorological Service, which continued to operate it until 1915 when meteorological observations were discontinued. The site and the equipment were then abandoned until 1948 when the Australian National Antarctic Research Expeditions established a permanent presence on the island.

certain, certain way he lived his own, private life,
but nevertheless, they shut off his gas; nevertheless,
the bank foreclosed; nevertheless, the landlord called;
nevertheless, the radio broke,
And twelve o’clock arrived just once too often,”
—Kenneth Fearing (1902–1961)
