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.
