 Despite its 2.5 million watt effective radiated power, it only provided a Grade B signal to Fayetteville and could not be seen at all in Rogers and points north.For most of this station's first ten years on the air, viewers in the northern part of the area had to rely on cable to watch the station.Much of the far northern part of the market got a better signal from KSNF in Joplin, Missouri (which, incidentally, switched from CBS to NBC in 1982).
