CKSB-10-FM is a Canadian FM radio station, broadcasting at 88.1 MHz serving the Winnipeg Capital Region in Manitoba. It is owned by the Société Radio-Canada (CBC) and airs the Ici Radio-Canada Première network. It had been licensed to St. Boniface, which was a separate city until it was annexed by Winnipeg in 1971. Studios are located on Rue Langevin in St. Boniface.
CKSB-AM signed-on at 6 p.m. on May 27, 1946 as a French-language commercial station, broadcasting from 607 College St. in St. Boniface. The building site was originally part of the St. Boniface College that burned down in 1922. It originally broadcast on a frequency of 1250 kHz with a power of 1,000 watts. The antenna was originally located three miles from the studio, at Dawson Rd. It was the first francophone station west of Ontario. It also aired programming in Ukrainian, Polish, German, Portuguese, Hebrew and Italian.
Two AM rebroadcast transmitters were added in the late 1960s — CBXF (Ste. Rose du Lac, now CKSB-1-FM at 92.9 FM) on February 1, 1968 and CBKB (St. Lazare, now CKSB-2) on March 12, 1969. Both stations operated on the 860 kHz frequency. Ste. Rose du Lac has now moved to 92.9 MHz. In 1958, the station moved to 1050 AM and boosted its power to 10,000 watts at all times. During the day, the station broadcast with a relatively omnidirectional pattern, but at night, it used a directional antenna,sending its signal toward the north, in order to protect Mexican Class A station XEG near Monterrey.
CKSB was independently owned and operated until 1973, when the CBC/Radio-Canada network purchased the station to expand its French network service.
On March 16, 2006, the Canadian Radio-television and Telecommunications Commission (CRTC) approved an application by the station to implement a "nested" city-grade 2.8 kW FM rebroadcaster at 90.5 MHz in Winnipeg, "CKSB-10-FM", to simulcast the AM programming heard on 1050 kHz. This FM signal was set up due to address reception problems in parts of Winnipeg.
In September 2012, the CBC applied to replace both CKSB's AM transmitter (1050) and its nested FM repeater (90.5) with a new 100 kW FM signal on 88.1 MHz. This application was approved by the CRTC on March 18, 2013. The station began simulcasting in October 2013, then ceased operation on AM 1050 and 90.5 FM on January 3, 2014.
The station uses the call sign of its now-former Winnipeg translator, CKSB-10-FM, because the call letters "CKSB-FM" are already used for Radio-Canada's Ici Musique outlet at 89.9 MHz.
The station's current local programs are Le 6 à 9, in the mornings from 6:00 a.m. to 9 a.m., Midi Plus Manitoba from 12:30 p.m. to 1 p.m. and L'Actuel in the afternoons, 4 p.m. to 6 p.m.
CKSB-10-FM also produces the Saturday morning program for Western Canada, Les samedis du monde, broadcast from 7:00 a.m. to 11 a.m. local time. Broadcast live in Manitoba, this program is tape delayed in Alberta and in British Columbia; in Saskatchewan, it simulcasts CKSB-10-FM from November to March, while it is tape delayed from March to November. CKSB-10-FM also produces holiday programs for western Canada - Les matins de l'Ouest, Les midis de l'Ouest and Le monde chez nous - replacing regional programming on Première outlets in western Canada.
