Radio WHO-AM (News1040)

WHO is a clear channel radio station broadcasting 50,000 watts on 1040 AM with a news/talk format. The station is owned by Clear Channel Communications and is located in Des Moines, Iowa. The station can be heard over most of the continental United States during nighttime hours. During daytime hours, its transmitter power and Iowa's flat land allows it to be heard in all of Iowa, as well as parts of Minnesota, Illinois, Missouri, Nebraska, Kansas, South Dakota, and Wisconsin.

WHO first began broadcasting on April 11, 1924, from the top floor of the Liberty Building in downtown Des Moines. The callsign came from the fact that during the 1920s people searching for stations on the radio dial would ask, "Who is it?" The station was originally owned by Bankers Life, which is now the Principal Financial Group. After the FRC's General Order 40 reallocated frequencies in 1928, WHO ended up sharing time on the same frequency with WOC in Davenport. In 1930, B. J. Palmer, owner of WOC, bought WHO, and the two stations operated together as WOC-WHO until a new 50,000-watt transmitter near Mitchellville began operating on November 11, 1933. (WOC ceased broadcasting that day but returned on another frequency a year later.) Palmer later changed the call letter slogan to represent 'With Hands Only', which he had adopted as a slogan of Chiropractic. WHO moved from 1000 AM to the current 1040 AM on March 29, 1941, as a result of the North American Radio Broadcasting Agreement. Today WHO is one of only two 50,000-watt AM radio stations in Iowa (KXEL in Waterloo is the other), though WHO's signal is non-directional and KXEL's is directional .

In 1948, WHO-FM 100.3 signed on the air; WHO-FM has changed formats and call letters several times since then and now broadcasts as KDRB, "100.3 The Bus." In 1954, WHO-TV began broadcasting on channel 13.

WHO was owned by the Palmer family until Jacor Broadcasting purchased the station in 1997; Jacor merged with Clear Channel Communications a year later. WHO and the other Clear Channel radio stations in Des Moines (KDRB, KPTL, KKDM, and KXNO) continued to share a building with WHO-TV until they moved into a new facility in 2005.

For many years, WHO has used an owl as its mascot--an apparent play on its call letters.
