roots, and world. Historic music archive CKUA's music library boasts one of the largest and most diverse music collections in Canada, with more than 250,000 CDs and LPs, including 10,000 78 rpm records, as well as a few aluminium transcription discs, 45s, and other various media formats. Broadcast locations CKUA was headquartered in the Alberta Block building on Jasper Avenue in Edmonton starting in 1955. In October, 2012, CKUA moved into its current location in the Alberta Hotel building, with its first broadcast from the new location on October 15, 2012. Broadcasting issues The station's original transmitter was located at 580 kHz in Edmonton. It operated at 10,000 watts. Due to its location near the bottom of the AM dial, as well as its transmitter power, it was powerful enough to cover nearly all of Alberta's densely populated area. It added an FM simulcast in 1947. Starting in the 1970s, CKUA built a network of 16 FM repeaters across Alberta. CKUA also broadcasts in western Canada on select cable and satellite providers (such as SaskTel, who carries CKUA across Saskatchewan as a Lloydminster station). As of February 29, 1996, CKUA became the first radio station in Canada to stream their broadcast online, and now has upgraded the service to carry an unlimited number of streams. The station currently has more than 250,000 weekly listeners. Because of CKUA's extensive coverage, the station was one of only a handful of broadcasters (another being CTV Two Alberta, formerly Access) to carry the Alberta Emergency Public Warning System. The provincial government-funded programme provided the station with 12% of its annual income until the contract was lost to an Ottawa firm, Black Coral Inc., in January 2010. CKUA announced plans to shut down its legacy 580 AM signal, the longest continuously-used AM frequency in Canada, in the spring of 2013. It would have needed to invest as much as $5 million to upgrade the transmitter site to modern standards, an amount it could not afford. However, CKUA did not receive formal approval from the CRTC until September 12, 2013. AM 580 went off the air on November 21, 2013, the station's 86th anniversary.
