2JJ broadcasting at 11:00 am, Sunday 19 January 1975, at 1540 kHz (which switched to 1539kHz in 1978) on the AM band. The new Australian Broadcasting Corporation (ABC) station was given the official call-sign 2JJ, but soon became commonly known as Double J. The station was restricted largely to the greater Sydney region, and its local reception was hampered by inadequate transmitter facilities. However, its frequency was a clear channel nationally, so it was easily heard at night throughout south-eastern Australia. Its first broadcast demonstrated a determination to distinguish itself from other Australian radio stations. The first on-air presenter, DJ Holger Brockmann, notably used his own name (a deliberate reference to his former work for top-rated Sydney pop station 2SM). Owing to 2SM’s restrictive policies at the time, Brockmann, whose real name was considered “too foreign-sounding”, had been forced to work using the pseudonym “Bill Drake” in prior positions. After an introductory audio collage that featured sounds from the countdown and launch of Apollo 11, Brockmann launched the station’s first-ever broadcast with the words, “Wow, and we’re away!”, and then cued The Skyhooks’ You Just Like Me ‘Cos I’m Good in Bed.
