CKDO is Oshawa's classic hits and oldies station, owned by Durham Radio and heard on 1580 AM and its FM rebroadcaster at 107.7. The station first signed on October 5, 1946, making it one of Durham Region's oldest broadcasters, and it moved to the clear-channel 1580 frequency in 2006. Serving the eastern Greater Toronto Area, it pairs oldies with a strong commitment to local Oshawa and Durham news.
