WSUI (910 AM) is a public radio station in Iowa City, Iowa, in the United States. It is operated by the University of Iowa and a member of Iowa Public Radio. Its signal serves most of eastern Iowa. WSUI is one of two National Public Radio member stations serving eastern Iowa, the other being KUNI in Cedar Falls. It is a sister station to all-classical KSUI.
WSUI began in 1919 as 9YA, a 10-watt experimental station operating out of the Physics Building. It was granted a full license on June 26, 1922 as WHAA, becoming WSUI in 1925. It is the oldest educational station west of the Mississippi River.
The studios were located for many years in the University's Engineering Building. They were relocated to a former supermarket building south of campus in the late 1990s, when expansion of the College of Engineering required WSUI-KSUI to vacate their space in the Engineering Building.
The experimental station call sign, 9YA, had been used by the State University of Iowa—now University of Iowa—since 1911 when the first Morse code transmitter was installed. Carl Menzer, who started work at the station in 1917 as a student and later went on to become station director, brought vacuum tube technology to 9YA in 1919, signaling the start of regularly scheduled voice and music broadcasts.[1][2]
The broadcast towers are located about 10 miles south of Iowa City. A single tower is used during the day, which covers almost all of eastern Iowa and part of western Illinois due to the area's flat land and near-perfect soil conductivity. Three towers are used as a directional array at night to protect WLS in Chicago at nearby 890 AM, concentrating the signal northward toward the Cedar Rapids and Iowa City areas.
