VK7OTC is on the site of coast radio station, VIH, which
opened in 1912 in time to communicate with Mawson's
expedition to Macquarie Island and Antarctica. VIH closed
in 1992. The original 5 KW spark transmitter was replaced
by a 2 KW valve in 1926. VIH was operated by the PMG,
RAN, AWA and finally the Overseas Telecommunications
Commission, hence our call sign VK7OTC.
