[GreenKeys] AN/MRC-32 RATT

[WA5CAB at cs.com]

Well, yes.  That's exactly what TM 11-487A says.  All of the hard data 
(either the manual on the set, or reference manuals) I have indicates that a 
specific vehicle is included in the list of components.  This is not the case 
with ARC, GRC or VRC.  Further, most (but not quite all) radio sets included 
in AN/MRC- sets were built for something else originally.  For example, 
AN/MRC-20 consists of an M38A1 carrying a large chest containing AN/ARC-3, 
AN/ARC-8 and AN/ARC-27, plus antennas and some interconnection (retransmission) 
boxes.

Definition distinguishing between "M"RC and "V"RC is that in the first case 
the vehicle has no other purpose but to carry the radio equipment and in 
the second, but in the second case, the radio is intended or designed for 
installation in vehicles but the primary purpose of the vehicles is other than 
hauling the radio.  Now, it's a fine point as to what else you could do with 
the deuce-and-a-half hauling an SCR-399 or an AN/GRC-26.  But in a few hours 
you could dismount the shelter and go off and do something else with the 
truck.  Which was on the Unit TO&E as a one of several trucks, not as a radio 
station.

One other comment, the JAN system first began to appear in late 1942.  I 
have a wall chart dated June 1943.
