[ARC5] Contract 74912 - June 29th, 1940

[WA5CAB at cs.com]

I have a record entry in my database for a CBY-46181 with the following:

Navy Type #              46181
DESCRIPTION          RCVR, 0.52-1.5 MC,  14 VDC
SERIAL #                 992
CONTRACT #           NOs-74912
CONTRACT DATE    1/43
A,R,C, #                   9201
SET                         ARA-2

There is no indication that I ever actually had the set (which there would 
have been had I entered it from something on hand.  The record isn't dated 
or attributed, which I've been routinely doing for at least 20 years.  So I 
don't know when or from whom I got the entry.  It could have been from as far 
back as the early to mid 1980's because although in its more or less 
current form it dates from 1994.  But some of the information in it dates back to 
the C-64 days.

In any case, I probably got the information from someone who had the 
receiver.  I had heard rumors over the years that the AN/ARC-5 project began as 
ARA-2.  But I never heard anything about its starting out as a 14 VDC set.  So 
I don't know whether that was reported because the receiver had be hacked 
or because it was built that way.  The Navy Type # for the ARA BCB receiver 
is 46145, so the number fits as being later.  But the A.R.C. part number for 
the R-24/ARC-5 is 9603, not 9201.  So this wouldn't be an R-24 with an early 
nameplate.

9201 isn't in AN 16-30ARC5-2 (the final number of the LF, MF and HF 
AN/ARC-5 Maintenance Manual).  But 9202 is.  And turns out to be the 14 VDC single 
receiver rack made in very small quantities for the R-148/ARC-5X.  

So it does appear that A.R.C. made some equipment in 1943 and invoiced the 
Navy under the old 1940 Contract.
