Sure, Duncan.

Socket 1 (I presume that this is the LH one):

A  microphone audio
B  External 24v supply or battery charging supply
C  PTT
D  Earth return
E  Key
F  Phone audio output
G  Low power select

Socket 2 is the same, except that G is "fixed level audio"

The sockets are  Amphenol 62GB-5016-10-7S

I've been thinking of making an external adaptor box myself to try
to standardise between "military" and "ham radio" accessories. If
I get around to it, it'll probably be to CAIRO standard.


Now, while we've got all your attention and thinking 931s, does anyone
in the UK have a haversack (and/or carrying frame) for sale, or even to 
borrow to have a replica made?
