With little adjacent channel interference, KOMA had a tremendous reach with its 50,000 watt signal. In many areas of the plain states and the West, KOMA was the only Top 40 station serving some rural areas and small towns. At night, KOMA could be picked up in such far away locales as Denver, Salt Lake City, Albuquerque and Phoenix. Fans of rock 'n' roll and top 40 music living in North and South Dakota in the 1960s and 1970s, for example, frequently waited until evening to enjoy listening to music on KOMA from a great distance away.
