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.

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.

Two local hosts have talk shows on weekdays, Jeff Angelo in late mornings and Simon Conway in afternoon drive time.

The rest of the schedule is made up of nationally syndicated programs, mostly from co-owned Premiere Networks: The Clay Travis and Buck Sexton Show, The Sean Hannity Show, Our American Stories with Lee Habeeb, Coast to Coast AM with George Noory and America in the Morning with John Trout.

[10] After the FRC's General Order 40 reallocated frequencies in 1928, WHO was assigned to 1000 kHz on a time-sharing basis with WOC in Davenport.

This company purchased both WOC and WHO, which were then synchronized to simultaneously broadcast identical programs on their shared frequency, each using a 5 kilowatt transmitter.

The FM station has changed formats and call letters several times since then and now broadcasts as KDRB, "100.3 The Bus".

WHO and the other Clear Channel radio stations in Des Moines (KDRB, KKDM, KLYF, and KXNO) continued to share a building with WHO-TV until moving into a new facility in 2005.

[15] Around 1935, Reagan became a host on a WHO news show featuring commentary by H. R. Gross, who would later be elected to the United States House of Representatives for Iowa's 3rd congressional district in 1948.
