 A one-week broadcasting licence was going begging after an event planned for Healesville's contribution to Victoria's 150th Anniversary celebrations was abandoned.A hastily assembled crew stepped in, clutching armfuls of records, to take to the airwaves on equally hastily assembled home equipment - and Healesville Co-operative Broadcasters was born.Its studios, from which numerous "test transmissions" were broadcast, were located in several temporary venues, including the ladies toilet of the old Healesville railway station, an office, a concrete shed and a mobile van in a cow paddock.
