RSN Racing &amp; SportRSN Racing &amp; Sport RSN Racing & Sport RSN Racing & Sport (ACMA callsign: 3UZ) is an Australian radio station in Australia. Owned and operated by thoroughbred, harness and greyhound racing bodies of Victoria, it broadcasts a sports radio format to Melbourne, and to much of Victoria through various repeater stations. First broadcast as 3UZ on 8 March 1925, it was in 1986 sold to the state's racing bodies. Today, the majority of the station's programming is dedicated to coverage of thoroughbred, harness and greyhound racing. History. As 3UZ. 3UZ was 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"". Initially, the station broadcast on 930 kHz AM from studios in 45 Bourke Street, under Victoria's first "B-class" licence, permitting it to broadcast paid advertisements. At the time, other stations were dependent on subscriptions. 3UZ's first lineup saw Keith Cooke engaged  as chief announcer, with Leslie Dobson, George Cowley, Dulcie Cherry and Gertrude Hutton included as the first "night artists". In 1929, 3UZ, along with rival Melbourne station 3DB, participated in experimental television broadcasts using the "Radiovision" system. In 1978, with the implementation of 9 kHz spacing on the AM band, the station moved to 927 kHz. Over the sixty years between 1925 and 1985, the station achieved consistent top ratings as "The Greater 3UZ", with stars including Stan "The Man" Rofe, John McMahon, Nicky Whitta, Graham Kennedy, Happy Hammond, Allan Lappan, Don Lunn, Ken Sparkes, John Vertigan, Neil Thompson, Martha  Gardener, Stephanie Deste, Don Lane and Bert Newton. In 1985, the Nilsen family sold 3UZ for $9.2 million to Launceston-based ENT Ltd., associated with the controversial figure Edmund Rouse. Programmes. A handful of programme titles from 3UZ's history: As Sport 927. However, just one year later, 3UZ was onsold to the Victorian thoroughbred, harness and greyhound racing bodies. In 1988, the station re-introduced horse racing coverage, leading the station to rebrand as Sport 927 in 1996. Throughout the late 1990s and 2000s, the station would acquire various AM and FM open narrowcast radio stations, as well  as Shepparton-based 3SR, extending coverage across Victoria. It also established 3BT as a Ballarat-based rebroadcaster as 3BA transferred to the FM band, and affiliated with ACTTAB Radio and TOTE Sport Radio. In 2004, the station participated in DAB digital radio trials in Melbourne, alongside 3RRR, ABC Classic FM, ABC DiG, Radio 2 and SBS Radio. In May, the station took Nielsen Media Research to court, citing "hundreds of thousands of dollars" in lost advertising revenue due to ratings reporting policies. The case returned in April, and reached a settlement in September. As RSN Racing and Sport. Briefly, in  2011, the station rebranded as Radio Sport National. However, coinciding with the pending sale of Tote Tasmania to Tatts Group, the station rebranded as RSN Racing & Sport. Following this sale, RSN was replaced on its Tasmanian frequencies by Brisbane-based RadioTAB. ACTTAB Radio eventually dropped RSN coverage, in favour of that from Sydney-based network Sky Sports Radio. Digital radio. In Melbourne, RSN Racing & Sport is simulcast on DAB+ digital radio. The station operates two separate stations – RSN Carnival and RSN Carnival 2,TAB Live. All four stations stream online. RSN Racing & Sport RSN Racing & Sport (ACMA callsign: 3UZ) is an
