CBU is a Canadian radio station, which airs the programming of the CBC Radio One network, in Vancouver, British Columbia. The station broadcasts on 690 AM (a clear channel frequency) and on 88.1 FM. CBU's newscasts and local shows are also heard on a chain of CBC stations around British Columbia.
CBU's studios and offices are in the CBC Regional Broadcast Centre on Hamilton Street in Downtown Vancouver. The AM transmitter is in the Steveston section of Richmond, British Columbia and the FM transmitter is on Mount Seymour. CBU (AM) transmits at 50,000 watts, the highest power authorized by the Canadian Radio-television and Telecommunications Commission (CRTC), allowing it to be heard throughout Metro Vancouver and around the British Columbia Coast. But because CKGM Montreal is the dominant class A station on 690, CBU must use a directional signal to avoid causing interference.
