How WSUI got its start


1916 antenna on the Old Capitol
The 1916 issue of The Transit, the technical journal of the University of Iowa College of Engineering, reveals that by 1916 a rather conspicuous aerial stretched from the "Hall of Physics" to the Old Capitol dome for the use of the SUI wireless station, 9YA. The transmitter was a 2 kilowatt Clapp-Eastham (spark) device operating at 400 kHz, and the receiver utilized an Audion vacuum tube similar to the one invented by Lee De Forest in 1906.
