WHO (1040 kHz "Newsradio 1040") is a commercial AM radio station in Des Moines, Iowa, United States. The station is owned by iHeartMedia and carries a conservative news/talk radio format, with studios on Grand Avenue in Des Moines.
WHO broadcasts with 50,000 watts, the maximum power permitted for AM stations in the United States. It uses a non-directional antenna from a transmitter site on 148th Street South in Mitchellville, Iowa.[4] WHO programming is also heard on the second HD Radio digital subchannel of co-owned KDRB (100.3 FM), and the station is Iowa's primary entry point station for the Emergency Alert System.
WHO dates back to the early days of broadcasting and is a Class A clear-channel station. The station is one of only two 50,000-watt AM radio stations in Iowa. The other is KXEL in Waterloo. However, WHO was originally a Class I-A, while KXEL was given Class I-B status, requiring a directional antenna at night, to avoid interfering with the other Class I-B station on 1540, ZNS-1 in Nassau, Bahamas. Due to WHO's high power and Iowa's flat land (with excellent soil conductivity), it has an unusually large daytime coverage area, equivalent to a full-power FM station. It provides at least secondary coverage to almost all of Iowa, as well as parts of Illinois, Missouri, Nebraska, Kansas, Wisconsin, Minnesota and South Dakota. At night, it can be heard at night across much of North America with a good radio, but is strongest in the Central United States.
