In 1922, CHCQ Calgary became CFAC, having changed call letters from CQCA a few months earlier, on May 9th. The CFAC call letters remain with the station today. To date, they represent the longest use of call letters in Alberta. CFCN had their call letters earlier, but has since changed call letters. CJCA Edmonton also had their call letters earlier, but was off the air for several months in the 1990s after the owner shut down the station and later sold it.

In 1925, Ted Rogers Sr. manufactured the world's first commercial AC (alternating current) tube at the newly established factory of Standard Radio Manufacturing Corporation Limited on Chestnut Street in Toronto. A few days later, Rogers displayed a Rogers Batteryless radio receiver using that very tube, at the Canadian National Exhibition (CNE) in Toronto. In 18 months, he had world's first AC radio station, as CFRB (Canada's First Rogers Batteryless) signed on February 10, 1927. CFRB's transmitter ran directly off utility-provided AC power; other stations ran on low-voltage batteries and DC (Direct Current) generators mechanically coupled to electric AC motors.

In 1931, Ted Sr. (pictured below) was granted Canada's first television license, and foresaw the coming of colour television. He later started Canada's first FM station, simulcasting CFRB-AM on the original 42 MHz FM band with 50 watts. And he did significant work on Radar before his death just before World War II.


In 1991, CILW Wainwright (Alberta) had its license renewed. And was authorized to change the source of 61 hours of its weekly programming from CHLW St. Paul to CFOK Westlock. Owner Nor-Net claimed it "would better respond to the needs of CILW's listeners." Hard to believe, given that Westlock is more than twice as far away from Wainwright as St. Paul.
