CBC Radio One

CBK is a Canadian clear-channel station, broadcasting the CBC Radio One network at 540 AM to most of southern Saskatchewan. Its studios are located at the CBC's broadcast centre at 2440 Broad Street in Regina, with an additional bureau in Saskatoon. The Regina facility also houses CBK-FM and CBKT.

The transmitter site is located in Watrous, the city of license. Watrous was chosen because of its excellent location to provide the best possible AM broadcast signal. The station operates as a 50,000-watt clear-channel station. Due to its location near the bottom of the AM dial, transmitter power and Saskatchewan's flat land (with superb soil conductivity), CBK's daytime signal reaches most of the southern two-thirds of the province, including Regina, Saskatoon, Yorkton, Swift Current, Lloydminster, Moose Jaw and Prince Albert. It also provides grade B coverage as far west as Calgary and as far east as Winnipeg, and reaches across the border into North Dakota and Montana. At night, it can be heard across much of the western half of North America. However, it is strongest in western and central Canada, North Dakota, Montana, Washington, Idaho and Minnesota.
