Shown here, on the cover of the October 1921 issue of Wireless Age, is H.O. Peterson of the University of Nebraska, Lincoln, at the controls of station 9YY, which he had designed. The station was part of the laboratory equipment of the Department of Electrical Engineering.

The station used four 50-watt type 203 tubes, and an additional two five watt audio tubes.

The station transmitted musical concerts twice daily at noon and 7:30 PM, and had been picked up in Nebraska, South Dakota, Iowa, Minnesota, Missouri, and Kansas. During daylight hours, the station had been pulled in 340 miles away in Aberdeen, South Dakota.

One summer concert had been carried live from the American Legion Band at a local amusement park. It was picked up by three microphones at the park, carried by Lincoln Telephone Company lines to the station, and transmitted to listeners in the neighboring states.

The station was under the general supervision of Dean O.J. Ferguson of the University’s Engineering College.
