KWSU (AM)

Research at the college in radio communication, initially with Morse code transmissions using spark-gap transmitters, reportedly began in 1908.

[3] In early 1916, the college was issued a license for a "Technical and Training School" station, with the call sign 7YI.

[4] However, in April 1917, due to the entrance of the United States into World War I, most non-government stations were ordered to cease operations.

Effective December 1, 1921, the Commerce Department, which regulated radio at this time, adopted rules formally defining "broadcasting stations".

[5] On June 21, 1922, the State College of Washington was issued a license for a new station operating on 360 meters in Pullman.

A transmitting antenna was constructed on the building roof, consisting of 6 wires strung between two 70-foot (21 meter) tall towers.

Longtime CBS newsman Edward R. Murrow began his career on KWSC, in addition to ABC sportscaster Keith Jackson and newscaster Barry Serafin.

[19] The call letters were changed to KWSU on March 1, 1969, ten years after Washington State attained university status.

KFAE facilities were located at the Mechanic Arts Building on the State College of Washington campus. The station's transmitting antenna was strung between two towers constructed atop the building. [ 6 ]
