Kw-7 "Orestes" Data (Teletype Machine) encryption system developed by NSA? refer: Jerry Procs site Service 1960-1980 (check dates) saw ubiquitous service Ships, Shore, Embassies, Nato installations, Air planes, and Tactical Field conditions. Walker spy ring and security compromises Iran Embasy seizure (years?) USS Pueblo incident aboard Kennedy Air force one cite (cite airman left circuit idle) 24 hour code and setting block- NSA distribution encryption materials Limited maintenance procedures as opposed depot level component and operation. note send button orange 3rd from right backlit when pressed sends phasing signal to other Kw-7 in circuit...when orange backlight goes out indicates both machines are in "synchronization" and message traffic can be exchanged. In circumstances when Radio Propagation conditions were poor and machines would not "lock" the older but more robust KL-7 "Adonis" off line encryption system could be utilized as back up. Note rotary alarm test switch far right. Used as an initial trouble shooting procedure. As switch is rotated through all posistions various combinations of front panel lights and alarm signals are produced. Field Technicians (who were not allowed to possess Technical Manuals of any sort) working purely from memory were alerted as to which faulty internal circuit board (number of boards?) needed to be replaced. Other maintainance issues sensitive to heat in hot environments, 24 hour code block wires subject to breakage, contact surfaces, and required a good ground especially under field conditions in sandy ie. desert conditions.
