Airborne teletypewriter AN/AGC-1

The transmission of information by teletypewriter means has proved itself, as shown by the number of civilian and military networks now in operation. The advantage of this method over voice lies in its reduced bandwidth and the production of printed copy. The teletypewriter code also allows specialized data-transmitting techniques to be used; the printed copy eliminates operator stand-by time. It was natural that the Air Force would want to extend its teletypewriter network to include its aircraft. Kleinschmidt Laboratories was awarded the contract to develop such an airborne teletypewriter, known as the AN/AGC-1. Basically, the Air Force required a send-receive type of teletypewriter incorporating a recorder-reproducer device for information storage, and a selective call system. This paper presents the results of the developments leading to the design of such a teletypewriter.
