KZMK (100.9 FM) is a radio station broadcasting a contemporary hit radio format. Licensed to Sierra Vista, Arizona, United States, it serves Southwestern Cochise County Arizona. The station is currently owned by CCR-Sierra Vista IV, LLC. (Cherry Creek Media)


This station first went on the air on September 9, 1973 using the call letters KTAN-FM and was the sister station of KTAN AM. It was the first FM station in southern Cochise County AZ. The station was owned by Ken Ferguson (Huachuca Broadcasting). KTAN's listening area is restricted by mountains on both the east and west sides. However, it does cover Sierra Vista, the largest city in Cochise County. This station changed its call letters to KTAZ-FM in 1978 when it began using Z-Rock as its music service. In 1989 the call letters were changed to KFFN. The current call letters of KZMK were adopted in 1995 after the owners purchased a rival FM station that was using the call letters KZMK. The rival station changed its call letters to KWCD.[1]
