The station first signed on to 1080KHz at 8:00 p.m. on March 3, 1954 (1954-03-03), from studios on the corner of 107 Street and 100 Avenue in Downtown Edmonton. On May 14, 1963 (1963-05-14), at 6:30 a.m., CHED switched to its current frequency of 630KHz.
For a significant portion of its history, CHED was Edmonton's (and North America's) most successful Top 40 station having a staggering 40% share of the local listening audience, but with the arrival of FM radio, it lost its listenership and moved to an all-talk format. Other news personalities on the network include Bob Layton, Bryan Hall and Ed Mason.
CHED is currently the most listened to radio station in Edmonton according to the Fall 2011 PPM data report released by BBM Canada.
