KNUV (1190 kHz) is a commercial AM radio station licensed to Tolleson, Arizona, and serving the Phoenix metropolitan area. It is owned by Denver-based Amigo Multimedia, Inc. The station has a Spanish-language radio format using brokered programming where hosts pay for their time on the station. Most programs are talk-based, with some music shows. By day, KNUV broadcasts at 5,000 watts. But 1190 AM is a clear channel frequency. So KNUV must reduce power at night to 250 watts to avoid interfering with other stations. It uses a directional antenna with a three-tower array at all times. The transmitter is on South 95th Avenue at West Jefferson Street in Tolleson. Programming is also heard on 250 watt FM translator K298CK at 107.5 MHz in Phoenix. History The station signed on the air on . It was originally owned by E. O. Smith and used the call sign KZON.
