I used one if these when I was assigned permanent duty in Frankfurt Germany. Was a well worn unit in 1973. Shortly after w=was replaced with an/grc 122 or 123 units can’t remember which. Was way better.
In 1962 I was in the 2ndBG/12th Infantry, !st ID. We used this with the KW-7 cypher machine. We could encrypt/decrypt teletype in line. We sent using the Tape reader. When you typed a message a perforated tape was made. You put the tape in the reader, pushed a button and it would encrypt and send it faster than you could type.
I was in the Army 81-86. I was using either a AN/GRC-142 mounted on a Gamma Goat.or a AN/VSC-3 (housed in a M577 command post carrier). The transceiver was a AN/GRC-106. Affectionally(?) called an "Angry 106. The teletypes were like you see here. A TT-98, and a TT-76 punch tape machine. The Crypto was the KW-7 (wire type). In the latter years the TT-98 was replaced with a AN/UGC-72. Around 1985, news came down that the KW-7 and it's keylist had been compromised. It had been going on for nearly 20 years. Look up the "Walker Spy Case". INT ZBK INT ZBZ K
I used one of these things during my 6 years in the USAR. Never sent a message. Did some rag chewing on 40 and 75, CW on 40 and rtty on 40. Leadership was impressed that we could communicate with anybody. Radio hut was way too small for any long use. I am 6'6" and the other ops were above 6'. The commo section booze was secured in the crypto safe.

That is a great, concise explanation of how it worked. Thanks.
I used one while in Germany 1st/94th FA 1971-1973. It also had a Crypto Box which was the state-of-the-art transmitting and receiving coder/decoder.

When I was in Germany 84-86, they switched over to GMC/Chevy pickups. The only people who still had gamma goats were wire and radio people.
Angry 46. In the 80's our RTTY trucks were GMC/Chevy pickups.
Thanks for uploading this fine historical resource! 73 de N8UX
