[GreenKeys] Teletype Corp M31- AN/AGA-1

[WA5CAB at cs.com]

Don, Duncan, et al,

AN/GRC-106 is a Vietnam War vintage set, at least a generation newer than the 
Korean War vintage AN/AGA-1.  And is anyway a ground set, not aircraft.  I 
have a TT-30 manual somewhere but just spent an hour looking for it without 
success.  However, it's unlikely it gives any application information.  

At a guess, most likely radio associated would be something like Collins 
18S-4 but I couldn't guess at the related transmitting and receiving converters 
(TU is a civilian term).  Aircraft maybe P2V.
