[Milsurplus] Data call for RU/GF junction box photos

[Mike Hanz]

I've had some discussions recently about connectors for the RU/GF series 
of command sets, and one of the frequent things that comes up is the 
serious confusion over which connectors go with which sets.

In the wisdom of those who made decisions back then (Aircraft Radio 
Corporation, apparently), the connectors are not marked with a five 
digit Navy number, but with a two or three digit number, like 37 or 
133.  Obviously, one could go through each of the manuals from the 
original RU to RU-19 and ferret out all the numbers, but it occurred to 
me that a quicker way might be to solicit photos of each one from folks 
out there who might have one of the junction boxes.  A phone or Ipad 
picture might even be good enough, as long as it is reasonably clear and 
I can crop it and still read the numbers.  Note that those boxes that 
have the resistor doghouse need to be taken from 15 feet or so because 
of parallax to see the connector numbers beside the doghouse.  To get 
this started, I've set up a web page to catalog these photos as they 
come in - http://aafradio.org/docs/RU-GF_junction_boxes.html

If there is any interest, I'll do the same for the SCR-183/283 sets, 
though some of those never had an official junction box as a part of the 
set.

It is probably too much to hope for to get photos of junction boxes for 
RU sets down in the low single digits, but you never know. Please send 
the photos to this address, along with whether you would like 
attribution or not: aaf-radio-1 at aafradio.org

Many thanks for the help,
