CKOF-FM (104.7 MHz) is a French-language commercial radio station in Gatineau, Quebec, serving the National Capital Region including Ottawa. Owned and operated by Cogeco, it broadcasts a talk radio format, calling itself "104,7 FM". Some programming is shared with sister station CKOI-FM Montreal. The radio studios and offices are in the Chemin des Terres neighbourhood of Gatineau. CKOF-FM has an effective radiated power (ERP) of 31,000 watts, with a maximum of 100,000 watts. The transmitter is located in Camp Fortune, near Gatineau Park. History The station originally began broadcasting in 1968 on the AM band. It was CJRC, on 1150 kHz with a daytime power of 50,000 watts and a nighttime power of 5,000 watts as a class B station. It used a directional antenna with slightly different daytime and nighttime directional patterns in order to protect various other stations on that frequency – particularly CKOC in Hamilton, Ontario. The station was signed on the air on June 3, 1968 by Raymond Crepeau, Marcel Joyal, Robert Campeau and Gerard Moreau with the presence of Pierre Elliott Trudeau, the then-prime minister of Canada (and father of future prime minister Justin Trudeau) as part of the Radiomutuel network. Originally its headquarters were at the Sparks Street Mall in Ottawa but were later moved in the old city of Gatineau in the 1980s after a stay on Belfast Road in Ottawa. It became part of the Radiomédia network (later known as Corus Québec) on September 30, 1994, after Radiomutuel merged with Télémédia (that network's Gatineau station, CKCH, was closed down). On November 24, 2006, the CRTC authorized the station to switch to the FM band. The change of frequency forced CHMY's transmitter in Arnprior, formerly on 104.7, to move to 107.7 FM. On April 16, 2007, at 7:00 a.m. EDT, CJRC made the move to the FM band on 104.7 MHz as CJRC-FM Le FM parlé de l'Outaouais. On June 12, 2008, CJRC-FM received approval to increase power from 2,900 to 36,000 watts. In March 2009, Corus announced plans to drop the talk radio format on CJRC, CHLT-FM in Sherbrooke, CHLN-FM in Trois-Rivières and CKRS-FM in Saguenay, in favour of a classic hits-oldies format branded as "Souvenirs Garantis", effective on March 28, 2009. Since the implementation of the new CJRC-FM on 104.7 in 2007, the old 1150 AM has been simulcasting the programming of CJRC-FM which was originally to be shut down on
