[ARC5] RAT-1

[WA5CAB at cs.com]

RAT and RAT-1 weren't prototypes.  They were production models, albeit 
built in very small quantities.  RAT-1 receivers are the same, except for 
nameplates, as two of the RAV receivers.  AN/ARC-5 started as ARA-1 and ATA-1 but 
got caught in the nomenclature system change.  One could argue that ARC-5 
was actually built as AN/APR-4Y.  :-)  

GR P-540 built as GR P-540
ARC-1 built as        ARC-1
ARC-2 built as        AN/APR-1
ARC-3 built as        AN/APR-4
ARC-4 built as        AN/APR-4X
ARC-5 built as        AN/APR-4Y

FWIW, if then current nomenclature rules had been followed, AN/APR-4 should 
have been AN/APR-1A.  And there were both mechanical and electrical changes 
from ARA/ATA to AN/ARC-5.
