Radio-Cité (1977-1990)

CITE-FM signed on the air on May 7, 1977 as a sister station to 730 CKAC, owned by Telemedia.^[1] While it was still being approved and built, the station was called CKAC-FM, though it would instead go on the air as CITE-FM. The previous year, a co-owned FM station in Sherbrooke at 102.7 began using the call letters CITE-FM. With the sign-on of 107.3 in Montreal, the Sherbrooke station became CITE-FM-1, a designation that usually indicates a full-time rebroadcaster of the non-numbered station, though CITE-FM-1 continued to have its own local personalities and advertising with a similar playlist. CITE-FM-1 is also easily heard in the southeastern portion of the Montreal market, and Telemedia likely used the similar calls for overall ratings purposes involving both stations. Currently, CITE-FM-1 continues to simulcast some programming from Montreal but retains its own local advertising and some local personalities.

Telemedia originally planned CITE-FM to be on 93.5 MHz, but the Canadian Radio-television and Telecommunications Commission instead arranged for CBM-FM to shift from 100.7 MHz to 93.5  MHz to accommodate CBF-FM. Telemedia then took the 107.3 allocation instead.

CITE-FM aired a beautiful music format as Radio-Cité. It played instrumental cover versions of popular songs, along with some French and English middle of the road (MOR) vocals. Over time, to attract younger listeners, the number of vocals increased while the instrumental music was scaled back.

Rock-Détente (1990-2011)

In 1990, CITE-FM completed its move from instrumental to vocal music, switching to a soft adult contemporary format. "Radio-Cité" was renamed Cité Rock-Détente. Telemedia's radio stations in Quebec and the Maritimes were purchased in 2002 by Astral Media.^[2] CITE-FM became the sister station of Astral's CKMF-FM. Because of federal competition laws, Astral Media was not permitted to keep 730 CKAC. Following the transaction, CITE-FM left the CKAC building that was on the corner of Sainte-Catherine Street and Peel Street, relocating to CKMF's building at the corner of René Lévesque Boulevard and Papineau Avenue.

In 2004, Astral revamped the Rock Détente network with a new logo. This resulted in Cité Rock-Détente being renamed as simply "107,3 RockDétente." The station no longer uses its call letters on the air, except when required by CRTC regulations.

Rouge FM (2011-present)

On August 18, 2011, at 4:00 p.m. EDT, the station ended its 21-year run with the "RockDétente" branding. All "RockDétente" stations, including CITE, were rebranded as Rouge FM.

The last song under "RockDétente" was "Pour que tu m'aimes encore" by Celine Dion, followed by a tribute to RockDétente's 23-year history. The first song under "Rouge" was "I Gotta Feeling" by Black Eyed Peas.
