CHQR is a radio station owned by Corus Entertainment operating in Calgary, Alberta. Broadcasting at AM770, it airs talk radio programming. With the exception of one show, all of CHQR's weekday programming is produced in-house. CHQR is also the exclusive radio voice of the Calgary Stampeders. CHQR is also the last AM station in the Calgary market to broadcast in C-QUAM AM Stereo. CHQR is a Class B station on the clear-channel frequency of 770 kHz.
CHQR's studios are located on 17th Avenue Southwest in downtown Calgary, while its transmitters are located just south of the Calgary city limits near De Winton.
As of spring 2013, CHQR is the third-most-listened-to radio station, the second most listened-to AM station, in the Calgary market according to a PPM data report released by BBM Canada.
The station originally began broadcasting at 810 AM in 1964 and received approval to move to its current frequency in 1985.
On November 9, 2011, Corus Entertainment Inc., on behalf of its wholly owned subsidiary CKIK-FM Limited applied to the CRTC to add an FM transmitter to serve Calgary on the frequency 106.9 MHz to rebroadcast the programming of CHQR 770. This application was denied on May 24, 2012.
