 KGOL is one of only two 50,000 watt AM facilities serving the Houston area, the other being talk radio station 740 KTRH, owned by iHeartMedia, which runs 50,000 watts full-time.Because AM 1180 is a clear channel frequency reserved for Class A WHAM in Rochester, New York, KGOL must reduce power at night to 3,000 watts to avoid interference.KGOL uses a directional antenna at all times.
