Summary[edit]

Description
English: 330-PS-7755 (USN 709570): U.S. Navy’s Transistorized High-Speed Telegraph Set. The U.S. Navy’s new transistorized high-speed telegraph set provides the same functions as the present equipment and has the additional capability of handling 100 words per minute over each of the four channels simultaneously as compared to 60 to 75 words per minute over the old type sets. It is also anticipated that it will offer comparatively trouble-free maintenance with as many as 10,000 hours of maintenance-free operation being possible. The advantages of the new set have been made possible by the use of transistors throughout to replace vacuum tubes. March 14, 1956. (2/18/2015).
