The owner is probably concentrating on getting their two FMs moved. It wasn't worth their time and effort, compared to collecting a monthly LMA. I would think the "Christian" market in the area is pretty well saturated. Anyone considering putting Christian programming on 620, and I have no idea if anyone was considering that, would be wise to reconsider.
I wouldn't mind if the 'new upgraded' KCRZ did the "classic country" that the KJUG-AM had.
