WDEO is a radio station broadcasting on 990 kilohertz in Ypsilanti, Michigan. Broadcasting Catholic programming, WDEO is operated by Ave Maria Radio. WDEO began operations in 1962 as WYNZ, a 250-watt daytimer on 1520 AM with a country format, which changed to Top 40 later in the 1960s and later religious programming. In 1974, the station changed its calls to WYFC with the format remaining Christian-based. Former Domino's Pizza owner Tom Monaghan purchased WWCM in 1999 and changed it to WDEO, using the same calls and Catholic format formerly heard on AM 1290 in Saline (now WLBY). The station's studios were also moved from their longtime location on Cross Street in Ypsilanti into the Domino's Farms complex near Ann Arbor.
