CBEF is a Canadian radio station, broadcasting at 1550 AM in Windsor, Ontario. It airs the programming of Radio-Canada's Première network. CBEF is a Class A station broadcasting on the clear-channel frequency of 1550 kHz; in fact, the only full power station on this frequency in Canada.
The station's regional morning program is Matins sans frontières and the station airs the pan-regional afternoon program L'heure de pointe Toronto from CJBC in Toronto. The station also airs the provincewide program 15-30 Ontario weekdays. On Saturday mornings, the station airs the provincewide morning program Grands Lacs Café, Hosted and produced in Sudbury, with additional contributions from staff in Toronto. The provincewide programs airs on CBON and CJBC, as well as CBEF in Windsor. On all public holidays, the morning show Matins sans frontières airs as usual and afternoon shows L'heure de pointe Toronto from CJBC, or Ça parle au Nord from CBON-FM in Sudbury are heard provincewide (except Ottawa); 15-30 Ontario is preempted.
In the CBC's programming cuts announced on March 26, 2009, almost all of the station's local programming was slated for cancellation, meaning that the station had become effectively a rebroadcaster of Toronto's CJBC except for a skeleton staff of two anchors to present local news updates during the day and report on breaking news. A local lobby group, SOS-CBEF, organized to oppose the cutbacks, but their request for an injunction against the change was denied in July due to the presiding judge ruling that she did not have the appropriate legal jurisdiction to issue an injunction.
Matins sans frontières, a one-hour local morning program hosted by Charles Lévesque, was reinstated from 7 September 2010, and in May 2013 was expanded to two hours; as of Summer 2015, it expanded to three hours. The station continues to rebroadcast CJBC in other local programming blocks.
At the CRTC's license renewal for the CBC's services in 2013, the commission directed the network to maintain at least 15 hours per week of local programming on CBEF during the 2013-18 license term, due to the lack of other French-language radio services in Windsor.
The station also has a rebroadcast transmitter (CBEF-1-FM) in Leamington, on 103.1 FM. Due to AM reception issues in downtown Windsor, CBEF was also approved by the CRTC to operate a 620-watt rebroadcaster in Windsor at 105.5 MHz, provided that does not interfere with stations at or near this frequency, such as WQQO in Toledo or WWCK-FM in Flint. The callsign for the new rebroadcaster at 105.5 FM is CBEF-2-FM. As of April 1, 2012, 105.5 CBEF-2 is on the air.
In May 2012, the CBC filed with the CRTC seeking permission to move CBEF to CBE's previous transmitter and frequency of 1550 AM at 10,000 watts, and to establish a low-powered FM rebroadcaster (CBEF-3-FM) at 98.3 MHz in Sarnia. The change was requested due to concerns that rust may be affecting the now-obsolete facility, and that nearby hydro (electric) lines were also affecting its signal. The move, as requested, was approved by the CRTC on October 16, 2012; the station was given until October 16, 2014 to either implement the move or request an extension beyond that date. CBEF began simulcasting on, and transitioned entirely to 1550 AM in November 2012.
Despite the Class A designation and a clear-channel frequency, CBEF broadcasts on a directional signal to the northeast, to protect another Class A clear-channel, XERUV-AM Xalapa, Mexico, as well as smaller stations operating on that frequency (the closest being WLTI in New Castle, Indiana and WDLR in Delaware, Ohio).
On September 1, 2016, the CBC applied for permission to move their transmitter in Sarnia (CBEF-3-FM) from 98.3 to 101.5 MHz. The technical parameters for the move include a constant power of 1886 watts and a height of 107.4 meters EHAAT on the same tower as CKCI-FM. This would improve the station's coverage throughout Sarnia and the immediate Port Huron area, though it may be subject to co-channel interference from WWBN-FM from Flint, Michigan in the fringes of its listening area to the west of Port Huron. The station would also become short-spaced to WRVF in Toledo, Ohio also on 101.5, as well as CKNX-FM in Wingham, Ontario on 101.7 and CKOT-FM in Tillsonburg, Ontario on 101.3 MHz. The CBC's application to move CBEF-3-FM fom 98.3 MHz to 101.5 MHz was approved on February 3, 2017.
