[GreenKeys] AN/MRC-32 RATT

[Duncan Brown]

Dave,

Thanks, but I don't think it was an AN/MSC-29.  This shelter was much 
simpler, possibly an earlier version of the MSC-29?

There were just four TT-4s mounted in racks (not shelves as in the 
MSC-29).  There were just four TH-5s; I think they were mounted at about 
eye level, on your left as your came in the door.  There were NO TT-76s. 
There was no SB-22 switchboard or intercom.  There were spaces in the 
racks for at least four KW-7s (maybe more, as we sometimes ran full 
duplex circuit to our BN HQ.)

It was just a small, company level, comm center.  There was one main 
circuit to BN HQ and two circuits to our two out-stations supporting the 
1st ID brigades.  The outstations used GRC-46s with TH-5s.  So this 
small "comm center" served our needs.

Duncan
