It airs an oldies radio format with some news, talk and sports programs.

By day, KOFI is powered at 50,000 watts non-directional, the maximum for commercial AM stations.

But 1180 AM is a clear channel frequency reserved for Class A station WHAM Rochester, New York.

To prevent interference, at night KOFI reduces power to 10,000 watts and uses a directional antenna.

Ostrom retired from KOFI in 2008, though later returned to the airwaves at Kalispell station KGEZ from 2011 to 2017.
