CBW is the call sign of the CBC Radio One station in Winnipeg, Manitoba. The station broadcasts at 990 kHz. CBW is a non-commercial Class A Clear-channel station reserved for Canada under the North American Regional Broadcasting Agreement (NARBA) allocations.
CBW's studios are located on Portage Avenue (Winnipeg Route 85) in Downtown Winnipeg, while its transmitters are located near Beaudry Provincial Park in Springstein.
Due to the station's transmitter power and Manitoba's mostly flat land (with near-perfect ground conductivity), CBW 990 reaches almost all of southern Manitoba during the day and much of the middle portion of North America at night. The station is simulcast on CBW-1-FM at 89.3 MHz. The FM transmitter is atop Bell MTS Place Main, in downtown Winnipeg.
