WHO

A t-shirt from "Newsradio 1040" WHO in Des Moines, Iowa.  Their 50,000-watt signal covers most of Iowa during the day and much of the central United States at night.  They've been on the air since April 1924 when stations in Iowa were still assigned call letters beginning with the letter W.  Ronald Reagan worked at WHO as a sportscaster from 1932 until 1937.
