Up until 1964, a 500' transmitter for CBC Radio was located in Carman, Manitoba, at which time a new centralized communications tower at Starbuck, Manitoba was constructed to house CBW-AM, CBW-FM, CBWT, and CBWFT.
It must conform its signal to protect CBC Television's Winnipeg station, CBWT, which took to the air on channel 6 a year after WDAY-TV signed on.
