CBW is the call sign of the CBC Radio One station in Winnipeg, Manitoba. The station broadcasts at 990 kHz on AM. CBW is a Class A clear channel station reserved for Canada under the North American Radio Broadcasting Agreement allocations.
Due to the station's transmitter power and Manitoba's mostly flat land (with near-perfect ground conductivity), it reaches almost all of southern Manitoba during the day and much of the middle portion of North America at night. In addition, the station is simulcast on a low-power FM station at 89.3 MHz.
