K Rock 95.5 (call sign: 3CAT; stylised as K rock 95.5) is a commercial FM radio station based in Geelong, Australia. K Rock operates a mainstream Top 40 playlist and also airs Australian Football League matches involving the Geelong Football Club.
K Rock shares transmitter facilities with sister station 93.9 Bay FM (along with 94.7 The Pulse and 96.3 Rhema FM), broadcasting from a transmitter on top of Murradoc Hill on the Bellarine Peninsula. The license area covers the Greater Geelong area, Werribee and Western Melbourne, The Golden Plains, and the Surf Coast. K Rock also streams online via their website.
The station was originally known as 3GL and broadcast on the AM band, most famously 1341 AM from 1978 onwards. In 1990, it was transferred to 95.5 on the FM band and changed its name to K-Rock. In 2023, 3GL was revived on 1341 AM and now broadcasts as its own station independent of K-Rock.
History
3GL original run (1930 - 1990)
From 1930 to 1990, K Rock was known as 3GL on the AM band, broadcasting first on 1400 kHz, then 1350 kHz and later 1341 kHz. Although based in Geelong, it was notable for being received over most of the Melbourne metropolitan area.
3GL gave Happy Hammond his start in broadcasting in 1948 as a breakfast announcer. While at 3GL, Hammond also made his first TV appearance in 1948, long before the Tarax Show, as part of an exhibition using closed-circuit TV equipment for trial purposes. Towards the end of its time as an AM station, 3GL used the "3GL on the West Coast" slogan and associated jingles, many sung by Mike Brady.
For many years, 3GL was based in James Street, Geelong, but relocated after being granted the right to convert to the FM band in 1990.
3GL was offered an FM conversion upon the entry to the Geelong market of competitor BAY FM in December 1989. It continues to broadcast in its new form as a separate station from K-Rock.
