KNCO signed on the air on October 1, 1978; 46 years ago (October 1, 1978).[4] It broadcast a mix of middle of the road (MOR) music with news, talk and sports shows. In September 1982, it added an FM station.[5]KNCO-FM 94.1 was programmed with a separate adult contemporary music format.
KNCO was originally on 1250 kHz and was a 500 watt daytimer, required to be off the air from sunset to sunrise. But by the 1980s, the Federal Communications Commission was relaxing rules for clear channel frequencies. That gave KNCO the opportunity to move to the frequency of a clear channel station that would not have been permitted in earlier years.
In 1986, KNCO relocated to 830 kHz, increasing its power to 5,000 watts and was allowed to broadcast at night using a directional antenna. In the 1990s, it eliminated music from its programming, switching to an all-talk format with news and sports.
