Summary

[edit]
Description
English: Western Electric VT-1 Triode Receiver

During World War I, the US. made considerable advances in vacuum tubes for radio transmission and reception. The VT-1, developed in 1917, modulated the complex radio waves of voice transmission back into audio. Though radio voice communications were an important wartime advance, it saw almost no combat use. Picture taken at the National Air and Space Museum's Steven F. Udvar-Hazy Center in Chantilly, Virginia, USA.
