KIIS 101.1 (official callsign 3TTT) is a commercial FM radio station in Melbourne, Australia and is owned by the Australian Radio Network (ARN). The station was formerly known as 3DB and 3TT, broadcasting on 1026 kHz AM, before converting to FM in 1990.
The KIIS 101.1 playlist is primarily targeted at the 15–40 age group, the group most valued by advertisers. The station is part of the KIIS Network with sister stations in other major Australian cities – KIIS 106.5 Sydney, 97.3 FM Brisbane, Mix 102.3 Adelaide, 96fm Perth and Mix 106.3 Canberra.
3DB was awarded its broadcast licence in 1925 but did not make its debut on-air until 27 February 1927 in a fairly low key manner. The station was originally owned by Druleigh Business College, hence the callsign "DB". The original studios were located in Capital House, Swanston Street, Melbourne.
From 1929 until 1987 3DB was owned and operated by The Herald and Weekly Times Ltd, owners of The Herald and The Sun News-Pictorial newspapers. (Note: the modern Herald Sun was two separate papers at the time.)
3DB was one of the first Melbourne radio stations to initiate talkback programs in the late 1960s. In 1975, 3DB relaunched as a hit music station with the slogan DB Music. In August 1980, they rebranded as 100 3DB with a disco jingle that was also produced as a full length song, including an extended version. For a few weeks, 3DB played 100 3DB the song on a regular basis. The song was even played on at least one country station without removing or changing 100 3DB.
ln 1981, 3DB changed to a classic hits format while retaining the 100 3DB slogan and jingle. Coverage of horse racing had been shared in Melbourne between 3DB (Eric Welch), 3AW (Fred Tupper), 3XY (Harry Solomons), 3UZ (Bert Bryant) and The ABC (Jim Carrol and later Joe Brown). However, in 1983, 3UZ revamped its program lineup and cancelled all horse racing coverage, leaving 3DB as the sole outlet for racing on Melbourne radio. 3DB adopted the slogan Racing Radio and devoted much of its programming to horse racing.
In mid 1986, 3DB relaunched as a talkback station, while retaining its horse racing coverage. By 1987, the Victorian Racing industry had purchased 3UZ and hence took back exclusive rights to horse racing coverage effective from February 1988.
The Albert Family purchased 3DB in 1988 and changed the call letters to 3TT. (The letters TT referred to its broadcast frequency of Ten Twenty-six kHz.) The 3TT station name and a classic hits format were launched at 5am on April 2.
On 24 June 1990 at 12:00 am, the station converted to FM and became 101.1 TT-FM (with official callsign 3TTT). 3DB/3TT's old AM frequency of 1026 AM was returned to the government, and from 1991, it was used by the ABC for 3PB, which broadcast intermittently with live coverage of federal parliament (later to become full-time news/parliament station ABC NewsRadio). In 1993, TTFM relaunched as an adult contemporary music station.
In November 2014, Australian Radio Network announced that Mix 101.1 would be rebranded as KIIS 101.1 on January 19, 2015 with a new breakfast and drive show. The breakfast show, Matt & Jane will be hosted by Matt Tilley and Jane Hall. Additionally, the new drive show will be Hughesy & Kate hosted by Dave Hughes and Kate Langbroek.
In December 1988, 3TT moved from the old 3DB premises in the basement of the Herald and Weekly Times building at 44–74 Flinders Street, to new state-of-the-art studios in Queensbridge Street, South Melbourne. The station is now located in the inner suburb of Richmond in the Pelaco Sign building, sharing facilities with sister station Gold 104.3.
