Stereo 974 commenced broadcasting as 3WRB, initially covering a broader area; encompassing the Werribee and Melton areas now served by WYN FM and 979fm respectively. Previous committee members include the then-Member for Lalor, Barry JonesMP, who served as chairman between 1980 and 1982. In December 1990, the Australian Broadcasting Tribunal held a hearing to determine whether additional conditions should be placed on the 3WRB licence, or to suspend the station's licence entirely. Consequently, Western Radio Broadcasters was restructured from a corporation structure to a membership committee, and in 1992 the Tribunal ruled 3WRB would retain its licence, albeit with extra conditions including amendments to the licencee's constitution. In 1994, Southern Cross Broadcasting, owners of commercial radio stations 3AW and 3MP, sought a Federal Court injunction against 3WRB and 3INR from broadcasting the 1994 AFL season. 3WRB had intended to broadcast games featuring Footscray, as it did in the 1993 season. The injunction was granted, however the Australian Broadcasting Authority later ruled that both stations were not in breach of the Broadcasting Services Act 1992. In both cases, the broadcast of Australian Football League matches did not constitute a profit-making enterprise, and thus "do not change the nature of the service from community to commercial." Western Radio Broadcasters was also found to have breached the Broadcasting Services Act and the Community Broadcasting Association of AustraliaCode of Practice on several occasions. In February 1999, the ABA found the station had breached clauses 6.3 and 6.4 of the CBAA code for its handling of a dispute between a presenter and the committee of management. The station was also found in breach of its community radio licence for broadcasting advertisements during episodes of its Vietnamese language program in April and May 2000 and July 2001. In 1991, following the Coode Island fire, the station established an emergency warning system. In 2010, the station signed a memorandum of understanding and was certified as an official emergency broadcaster in its Melbourne West license area.
Closure
On 16 January 2020 the station ceased broadcasting. Management declined to comment to the Star Weekly; the newspaper speculated that a lack of funding may have made the station financially nonviable.
Stereo 974 had won several awards from the Southern Community Media Association, which incorporates community broadcasters from regional and suburban Australia. ! scope="row" rowspan="4" | 2009 ! scope="row" rowspan="7" | 2013 ! scope="row" | 2015
