History
Vancouver's CBC station was initially assigned the CBU (AM), CBR callsign from 1936 to 1952. The Calgary station was launched 12 years later in 1964. Before then, Calgary had been one of the last major markets in Canada without an owned-and-operated CBC radio station. Originally, Calgary's CBC outlet had been private affiliate CFAC. From 1948 to 1964, CBX (AM), CBX in Edmonton doubled as Calgary's CBC station as well, serving the southern two-thirds of the province from its transmitter at Lacombe, Alberta, Lacombe (halfway between the two cities). The new station took over CBX's old frequency at 1010 AM and its clear-channel designation, while CBX was reoriented to be Edmonton's CBC station. On March 16, 2006, the Canadian Radio-television and Telecommunications Commission (CRTC) approved an application by the station to implement a new, nested FM broadcasting, FM transmitter in Calgary itself to simulcast the AM programming, due to the AM signal's poor reception in some parts of the city. This new FM signal, CBR-1-FM 99.1 was launched on November 28, 2006. In recent years, the CBC has branded 99.1 as the main transmitter, even though 1010 is technically the main station. Various other AM and FM rebroadcasters have been installed throughout southern Alberta. On December 19, 2008, the licensee proposes to use a Subsidiary communications authority (SCA) channel to broadcast multi-cultural programs. On July 7, 2011, the CRTC approved an application by the CBC to relocate CBR's transmitter. All other technical parameters will remain unchanged.Local programming
CBR's CBC Radio One local programming, local programs are ''Calgary Eyeopener'' in the morning, and ''The Homestretch'' in the afternoon.Transmitters
In 1993, the CRTC approved the CBC's application to operate new FM transmitters at Medicine Hat 98.3 MHz and Etzikom 92.1 MHz. The new FM transmitter at Medicine Hat would replace CJMH the existing AM transmitter 1460 kHz owned by Monarch Broadcasting Ltd. Monarch would surrender the license of CJMH once the new transmitters were in operation. On April 30, 2015, the CBC submitted an application to add a new FM transmitter in Lake Louise, Alberta, Lake Louise with the call sign CBRQ-FM. If approved, the new transmitter would operate at 103.9 MHz to rebroadcast CBR. A transmitter currently listed at 103.9 MHz in Lake Louise. The transmitter was owned by the Lake Louise Community Association. The CRTC approved the CBC's application to operate a CBC Radio One transmitter at Lake Louise on July 14, 2015.References
