The studios were on the top floor of the Liberty Building in downtown Des Moines. 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.) Through most of its early years, WHO was a network affiliate of the NBC Red Network, broadcasting comedies, dramas, game shows, soap operas, sports and big bands.
