KMZQ 670 kHz, ("AM 670 KMZQ") is a commercial AM radio station in Las Vegas, Nevada. The station airs a conservative talk radio format and is owned and operated by Kemp Broadcasting & Digital Media. It was granted by the Federal Communications Commission (FCC) with construction permit to decrease its daytime power to 25,000 watts from the original 30,000. It uses a directional antenna by day. Because AM 670 is a clear channel frequency reserved for Class A WSCR Chicago, KMZQ must drastically reduce its nighttime power to 600 watts, using a non-directional antenna. The transmitter is off U.S. Route 95 at Alamo Road in Las Vegas.
