I was trying to figure out why the KECR History Card only goes back to the 1970s. I remember it was a Top 40 station in the 1960s. They had a KDEO Music Survey posted in a Michigan Record Store a lot of people in radio worked at. I couldn't figure out why. Was the station off the air for a long time and the License was cancelled, and another owner put it back on the air and relicensed it? It looks like it was once owned by the Bartells. I always thought it was KCBQ that was in that Group.
