. Jacor immediately re-branded KLYF as "Mix 100.3," but left the format unchanged for the most part. On June 17, 1998, the call letters changed to KMXD to represent Mix and Des Moines. Over time the station saw its ratings decline. Several steps were taken to try to counteract this, such as rebranding the station as "Mix 100" and trying an "80s and more" format. When these steps failed, the format was changed again to mainstream adult contemporary and the station was renamed "My 100." In 1999, Clear Channel Communications (the forerunner to current owner

The Bus

On May 25, 2006, the AC format came to an end, as KMXD was rebranded as "The Bus," simulcasting the adult hits format on 106.3, which at the time carried the KDRB call sign. This was a short lived, transitional arrangement to get listeners of 106.3 to move to 100.3. The adult hits format had performed better than expected, and the decision was made to move "The Bus" to the 100,000 watt signal at 100.3. On June 12, 2006, KMXD became KDRB "The Bus" on 100.3 FM. The 106.3 frequency switched to
