As of Feb 28, 2021, CBX is the 3rd-most-listened-to radio station in the Edmonton market according to a PPM data report released by Numeris.[1]
CBX started broadcasting September 8, 1948 on a frequency of 1010 kHz.[2] It was the third of three 50,000-watt Trans-Canada Network AM radio stations to sign on in the Prairie Provinces (the others being CBK in Saskatchewan and CBW in Manitoba). Prior to CBX's launch, Trans-Canada Network programming aired on commercial radio stations in Edmonton, namely CJCA, which continued to air CBC programming on a secondary basis after CBX signed on.[3]
Although CBX's initial studios were located inside the Hotel Macdonald in Edmonton, the station's transmitter was located near Lacombe,[4] roughly halfway between Edmonton and Calgary, in an attempt to serve the southern two-thirds of Alberta from a single transmitter.[5]
From the start, the CBX signal did not adequately cover either Edmonton or Calgary. To rectify this problem within Edmonton, a 250-watt rebroadcaster operating on 740 kHz was launched in the city in 1953. This rebroadcaster had the call sign CBXA.
Meanwhile, reception continued to be poor in Calgary.[6] In order to provide a long-term solution to the station's reception issues, in 1964, the CBC launched separate radio stations for Calgary and Edmonton while also decommissioning the original CBX transmitter.[7] Under the new setup, CBX was reoriented to be Edmonton's CBC station and took over CBXA's frequency of 740 kHz from a newly-constructed 50,000-watt transmitting site near Beaumont. At the same time, CBR signed on as Calgary's CBC outlet, using CBX's old frequency of 1010 kHz.[8]
In 2004, CBC Edmonton operations moved into a new digital broadcast facility downtown, bringing all operations of Radio and TV under one roof. The old TV facility on 75th Street had 70,000 square feet (6,500 m2), while the Radio building on 51st Ave. had 48,000 square feet (4,500 m2). The new combined facility has 38,700 total square feet. It is located at the Edmonton City Centre, on Winston Churchill Square.
On March 16, 2006, the Canadian Radio-television and Telecommunications Commission approved the station's application to add a nested FM transmitter at 93.9 MHz in Edmonton to simulcast the AM programming.[9] This relay, CBX-2-FM, officially began April 20, 2007.
Local programs produced by CBX include Edmonton AM, and Radio Active. CBX also produces half-hourly news bulletins between 5:30 AM and 6:00 PM each weekday. Provincial or national news bulletins air on CBX outside of those hours.
CBX also produces two music shows for the entire CBC radio networks: Saturday Night Blues and Canada Live air nationally on CBC Radio One/Sirius 137 and CBC Music, respectively.
The last few BBM radio ratings measurements have shown CBX steadily climbing in audience share in Edmonton. As of the spring 2009 BBM measurement, CBX is the second-most listened to radio-station in Edmonton, behind news-talk radio station CHED. Edmonton AM also ranks second in the morning, while Radio Active ranks fourth amongst the afternoon radio drive-time shows.[10]
