The station signed on the air in December 2007; 17 years ago (December 2007), after running test transmissions for several months. These tests were mainly to arrange the nighttime directional signal of the station, so it would not interfere with nearby KNZZ in Colorado or other stations on 1100 kHz. While testing, the station ran at half power (10,000 watts day and 1,000 watts night) to further limit the possibility of interference. 1100 AM is a United States clear-channel frequency, on which WTAM in Cleveland, Ohio, is the dominant Class A station. Upon signing on, the station began running at its authorized power.[4][5]
