Launched on 15 December 1974, it is Australia's first fully licensed FM radio station and it has since reached over 630,000 listeners.

[3] The station broadcasts from studios located at Chandos Street, St Leonards, to the greater Sydney region at a frequency of 102.5 MHz from a 50 kilowatt (ERP) transmitter located in the northern suburb of Artarmon.

Operational funding is principally derived from corporate sponsorship, arts partnerships, philanthropic donations, listener subscriptions, and the secondhand Book and CD Fairs held around the Sydney area.

Its regular presenter Mrs. Ann Ramsay died at the age of 91 on 1 April 2006.

Popular non-classical programmes broadcast by the station include the blues show Stormy Monday, which has aired on Monday evenings for three decades, and for many years was rebroadcast nationally by the Community Broadcasting Association of Australia (CBAA) satellite service.
