RSN Racing & Sport, formerly 'Radio Sport National' is a Melbourne based radio network dedicated to covering horse and greyhound racing. While much of the station is dedicated to Gallops, Harness and greyhound racing, it also covers other sports.
Unlike the other Australian racing networks, RSN is owned by a state's racing industry, and not by a betting agency.
RSN Racing & Sport was first founded by electrical engineer Oliver John Nilsen CBE, who was later to become a Lord Mayor of Melbourne. Known as "O.J.", Nilsen had created an electrical business, Oliver J. Nilsen & Co. (later Oliver J. Nilsen (Australia) Ltd) in 1916, manufacturing electric jugs, kettles, toasters, crystal sets and radios.
On 6 February 1925 Nilsen was granted a broadcasting licence and in March 3UZ commenced operations as "The Voice of Victoria" from 45 Bourke Street. Keith Cooke was engaged as chief announcer, and first night artists included Leslie Dobson, George Cowley, Dulcie Cherry, and Gertrude Hutton. After the launch, Listener-In magazine remarked that the station :
"... has received many favourable comments from Tasmania, South Australia and New South Wales, and many remote country districts in Victoria on its transmission."
3UZ had Victoria's first "B-class" licence, permitting it to broadcast paid advertisements. At the time, other stations were dependent on subscriptions. In 1929, 3UZ along with 3DB participated in experimental television broadcasts using the Radiovision system.
Originally on a frequency of 930 kHz, 3UZ later moved to 927 kHz in 1978 with the implementation of 9 kHz spacing on the AM band.
For the next sixty years the station achieved consistent top ratings as "The Greater 3UZ", with stars including Stan "The Man" Rofe, ], John McMahon, Cliff "Nicky" Whitta, Graham Kennedy, Happy Hammond, Allan Lappan, Don Lunn, Ken Sparkes, John Vertigan, Neil Thompson, Don Lane and Bert Newton.
In 1985 the Nilsen family sold 3UZ for $9.2 million to Launceston (Tasmania) media company ENT Ltd., associated with the controversial figure Edmund Rouse. In 1986 the Victorian thoroughbred, harness and greyhound racing codes purchased the station and racing was re-introduced in 1988.
It become known as "Radio Sport 927" in the 1990s. The station also gained a number of retransmitters in country Victoria, and later Tasmania (branded as TOTE Sport Radio) and the ACT (branded as ACTTAB Radio). Despite the differing radio frequencies (and interstate branding), they all used the "Radio Sport 927" name on air, before briefly becoming "Radio Sport National" in the late 2000s[when?].
In January 2012, the network was renamed "RSN Racing & Sport". This coincided with the pending sale of Tote Tasmania to Tatts Group, which would see RSN replaced on its Tasmanian frequencies with TattsBet's Radio TAB effective 27 March 2012.
