CBU is a Canadian radio station, which broadcasts the programming of the CBC Radio One network in Vancouver, British Columbia. The station broadcasts from Steveston on 690 AM (a clear-channel frequency) and from Mount Seymour on 88.1 FM. The station broadcasts from the CBC Regional Broadcast Centre on Hamilton Street in Downtown Vancouver. == History == The station was launched in 1925 as CNRV "The Voice of the Pacific" on AM 1100, owned by the Canadian National Railway radio network.〔(Historical information on CNRV ) at Canadian Communications Foundation〕 CNRV was acquired by the Canadian Radio Broadcasting Commission in 1933, becoming CRCV. In 1936, the CBC was created, taking over the CRBC's operations, and CRCV became CBR. The station moved to AM 1130 in 1941 (see Canadian allocations changes under NARBA), and to 690 in 1952 when the call sign was changed to its current CBU. Power was increased from 10,000 watts to its present 50,000 watts in 1967 with a transmitter site move to the Steveston shoreline. In 1947, an FM simulcast was launched on CBU-FM. Distinct programming on the FM station was aired for the first time in 1964. In early 2008, the Canadian Radio-television and Telecommunications Commission approved CBU's application for a simulcast of its programming on the FM band.〔(Broadcasting Decision CRTC 2008-252 )〕 On October 10, 2008, CBU began testing its FM simulcast on 88.1 FM as CBU-2-FM with an ERP of 19.5 kW and officially signed on soon after. Around the same time, the CBC also applied to broadcast on separate transmitters into Nanaimo, as well as the Sunshine Coast, with the intent to shut down the AM transmitter on 690 kHz if approved. The CRTC denied these other two transmitters due to the lack of available frequencies in the region. It is also the CBC Radio One station on the AM dial to serve the largest area of population ever since CBM-AM in Montreal became CBME-FM 88.5 in 1998, followed by CBL-AM Toronto's move to the FM dial back in 1999 as CBLA-FM on 99.1 FM. In 2011, CBC applied to the CRTC to increase the coverage area of CBU's 88.1 FM transmitter. CBC has proposed to increase the height of the antenna and to increase the ERP to 97.6 kW. The ability of increasing the signal coverage area is made possible by the fact that CHEK-DT moved from channel 6 to channel 49, as part of the over-the-air digital television transition. This CBC transmitter application was approved September 13, 2012.〔(Broadcasting Decision CRTC 2012-494 )〕 It is not known when these changes will be implemented. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「CBU (AM)」の詳細全文を読む スポンサード リンク
