This station serves southern Cochise County, Arizona and a small piece of northern Sonora, Mexico.
[3] This station went on the air using the call sign KBAZ (meaning: Bisbee AriZona) on October 12, 1979.
For several months prior to the change, billboards appeared around Cochise County featuring a flying saucer with the words "the starship is coming", leaving people to wonder what they meant.
KZMK entered into direct competition with KTAZ-FM, which was at the time the number 1 rock and roll station in the area.
KZMK was broadcasting with considerably less power than its rival KTAZ, (55 watts vs. 3,000 watts) and was called by broadcasters "the 50 watt blowtorch", however KZMK's signal covers a greater area, to include all of the populated areas in southern Cochise County as well as parts of northern Cochise County and parts of northern Sonora, Mexico because its transmitter is located on a mountain peak, at an approximate elevation of 7,000 feet above sea level.
