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's news network. 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 got its start prior to the era of broadcast radio, operating a "wireless telegraph" transmitter under the experimental radio call sign 9YA in 1911.[2] It began airing regular voice broadcasts in 1919. 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.[3][4] It was one of several AM stations opened by Midwestern universities in the early days of radio.

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 and KSUI to vacate their space in the Engineering Building.

WSUI's original three self-supporting broadcast towers were located just west of Mormon Trek Boulevard on the far west side of the campus. On June 29, 1998, a fierce line of thunderstorms packing winds of nearly 100 miles-per-hour toppled two of the towers. For months afterwards, WSUI's nighttime power output from the single remaining tower was limited to 1250 watts non-directional. Today, the towers are located about 10 miles south of Iowa City. A single tower is used during the day. Due to the transmitter's power and height, as well as Iowa's flat land (with near-perfect soil conductivity), its daytime signal covers almost all of eastern Iowa and part of western Illinois.

The early years

The assigned station call sign, 9YA (the "Y" in the call sign indicating operation under a Technical and Training School license) had been in use by the State University of Iowanow the University of Iowasince 1915, sometime after the installation of the university's first Morse code transmitter in 1913.[5] As of 1916 university electrical engineering students were operating a 2 kilowatt spark gap transmitter at a 750-meter wavelength that could be heard 1000 miles away, with two-way communications taking place within a 500-mile radius,[6] and were transmitting 300-word lessons on a regular schedule that dealt with wireless communication.[7] Carl Menzer, whose interest in wireless began at his high school in Lone Tree, entered the State University of Iowa as a freshman in 1917, and was later to become station director for WHAA/WSUI, a position he held until his retirement in 1968. After the WWI wartime moratorium on radio transmission was lifted in 1919, Menzer brought vacuum tube technology to 9YA, signaling the start of regularly scheduled voice and music broadcasts.[8]

The first “radio telephone” station, built using two donated experimental vacuum tubes, required use of two microphones for voice and for pickup of a windup phonograph, the microphones needing to be swapped frequently when the one in use became too hot to touch due to high current. In spite of audio quality and technical issues the station gained a following among a collection of crystal sets enthusiasts,[9] and within two years had inspired sufficient interest to cause State University of Iowa President Walter A. Jessup and other university educators to envision feasibility of advanced study in broadcasting, leading to application for a university broadcast license. On June 26, 1922 the call letters WHAA were assigned, by the end of September test transmissions were complete, and on October 17, 1922, the now official broadcast station was dedicated in a gala on-air commemoration that included talk by President Jessup.[10]

WSUI was a charter member of NPR in 1971, and was one of the 90 stations to carry the inaugural broadcast of All Things Considered.

Notable alumni

WSUI alumni include Harry Kalas, who served as Sports Director for the campus radio station WSUI and did play-by-play for all types of sports. Kalas received baseball broadcasting's highest honor—the Ford Frick Award from the Baseball Hall of Fame.

Early television

Iowa is a pioneer in educational broadcasting; it is home to two of the oldest educational broadcast stations in the world, the University of Iowa's WSUI and Iowa State's WOI. In 1933, The University of Iowa experimental TV station W9XK, later W9XUI provided twice a week video programming, with WSUI providing the audio channel.

By 1941, the FCC allocated TV channels 1 and 12 for the W9XUI television station.[11] This early attempt at educational broadcasting ended with US entrance into World War II.[12][13] The concept of pure educational television, which Dr. E.B. Kurtz and his Iowa colleagues pioneered, was buried by the commercial television system which dominated development of the electronic media in Iowa after World War II.[14] In 1970, WSUI-TV became KIIN, to create statewide Iowa Public Television network.
