G.R.Kilgore, research engineer of Westinghouse Company, East Pittsburgh, broadcasting on radio waves only a little over 3 inches in length.

In the microphone the voice is turned into electric impulses which are sent into space at the focus of the mirror.

The mirror sends out the signal as a parallel beam. A similar[sic] mirro[sic] receiver several miles away picks up the message.
