 In on-the-air references, the station drops the initial "K".Studios and offices are on East Plumb Lane, while it broadcasts from a three-tower transmitter facility off Chickadee Drive.KKOH broadcasts with 50,000 watts, the maximum power permitted by the Federal Communications Commission (FCC) for AM stations, but because 780 AM is a clear channel frequency, reserved for Class A WBBM in Chicago, KKOH must use a directional signal after sunset to avoid interfering with WBBM.
