CBU-FM (105.7 MHz) is a non-commercial public radio station in Vancouver, British Columbia. It is owned by the Canadian Broadcasting Corporation and it carries its CBC Music network. The studios and offices are in the CBC Regional Broadcast Centre at 700 Hamilton Street in Downtown Vancouver.
CBU-FM is a Class C station and the oldest FM station in British Columbia. It has an effective radiated power (ERP) of 31,7222 watts average (95,800 watts peak). The transmitter tower is atop Mount Seymour in the District of North Vancouver. Broadcast relay stations carry CBU-FM programming around British Columbia, as well as Dawson City, Whitehorse and Yellowknife.
The station signed on the air on December 12, 1947. At first it was an FM simulcast of Vancouver's original CBC AM station, which had the call sign CBR. It was rebranded as CBU-FM in 1952 when the Vancouver AM station was renamed. Because it was so far west, it was not part of the CBC's original FM network in 1960. But by the 1964 relaunch of the CBC FM network, CBU-FM was part of the chain.
As with most CBC Music stations, there is no Vancouver-specific programming on the station apart from short weather updates. However, Saturday Afternoon at the Opera and In Concert, both hosted by Bill Richardson, currently originate from Vancouver for the entire network.
CBU-FM-8 Whitehorse was originally known as CFWH-FM until 2009. CBNY-FM was known as CFYK-FM until June 3, 2013.
