[Milsurplus] Re: [ARC5] New addition

[Mike Hanz]

Finally returned from a month away with no e-mail and am slogging
through the 1400 messages as I have time.  Below is some info I have on 
the C-131 not in the manual.  The November 1945 ARMN writeup is actually 
more interesting than the manual, since it describes some of the plans 
and application for the receiver.  Somewhere I have notes that suggest 
it was used only in the Pacific theater - and that after the war was 
over - but I can't put a finger on it now.

The ARR-15 came in at the tail end of the war.  The R-105(non-A) I have 
here in the rig is the only one I've ever seen.  The contract appears to 
be circa about June of 1945, judging from the contract numbers on either 
side of it.  As Mike mentioned, it does not have an MF capability, but 
by then many of the aircraft using the ART-13 were also using Bendix nav 
receivers to cover those frequencies anyway.
