[Milsurplus] [GreenKeys] 1953 airborne RTTY unit

[couryhouse]

Alas that one was gone but George was very kind to the museum on  the other units... did yours has the tube in it or not Robert?
I have one with no case but has shock mounts on bottom! Weird... maybe another 31 variant!  I need to photo this after I clean it up a bit.
One western union model that was contributed  by one of our deaf patrons needs a new type wedgie wheel.. seems they are bakilite?  (Correct  me if I am wrong)....

I agree with Kluge.



But AN/PGC-1 used the Kleinschmidt TT-4A, B or C/TG. The airborne set using a 28 VDC Model 31 was AN/AGA-1. The printer was TT-30/AGA-1. I sold one to George H. in 1999.

The AF also had a RTTY setup invovling either the ARC-21 or the

ARC-65 - I forget which.  Used a TTY which I think was called AN/PGC-1

which I think was the airborne version of the Model 31.  The airborne

version ran off 26VDC, used a vacuum tube in the motor speed governor

circuit to reduce RFI from the governor contacts, and as I recall

the motor was also a dynamotor generating B+ for the associated RTTY

modem.
