KNST 790 AM

Licensed to Tucson, Arizona, this commercial AM station broadcasts at 790 kHz and is owned by iHeartMedia. It airs a conservative talk format and serves the Greater Tucson region, with studios on Oracle Road north of downtown and a transmitter in West Tucson near North Silverbell Road. The 790 AM frequency in Tucson traces its history to KCEE, which signed on October 1, 1958, under ownership of Associated Broadcasters of Arizona. Initially a daytime-only operation at 250 watts, the station eventually expanded to 5,000 watts by day and 500 watts at night. In the 1970s it operated as a full-service station with middle-of-the-road music and NBC Radio News. The KNST identity originated at 940 AM, where it launched a news and talk format in July 1981 after years as a country and then soft rock station. Following a sale to Nationwide Communications, a subsidiary of Nationwide Insurance, KNST carried ABC Talk Radio Network programming before moving to the more powerful 790 AM frequency on April 4, 1993, where it has remained since. Current programming features nationally syndicated conservative talk personalities alongside local content and news coverage, positioning the station as a flagship talk outlet for the Tucson market.
