According to Wikipedia — KDNR (whose call letters supposedly stood for “Dance and Romance”) launched sometime in the Spring of 1995, possibly with an all Dance or very Dance-heavy format. As demonstrated on this aircheck, by early 1997, the station had become rather unfocused as it attempted to broaden its music mix. I’m not sure if the station always used the very odd “Rhythm-Driven 106-3” name – any additional details would be much appreciated. Special thanks to Dave Dart – who at the time was program director of Rhythmic AC competitor KZRQ “Star 105 FM” – for recording this aircheck and meeting me for lunch when he was visiting Phoenix. The station now offers a CHR format known as “Z106.3”.
