Hello friends,

This is a long shot, but I figure I'd ask. I've been in search of a data
cable for my AN/UGC-74B, but it's proven extremely difficult and rare to
find the past year or so.

If anyone happens to have a spare one lying around, I'd be very interested
in obtaining it from you for a reasonable cost. Also, if you know of
surplus stores that may have these in stock, especially ones that are hard
to find via Google, please refer them to me. I've reached out to various
companies online with no luck.

The part number is SM-D-915889. A diagram of the cable may be found here
<http://radionerds.com/images/6/62/TM_11-5815-602-24-1.pdf> on pages 3-94
and 3-95 (144-145).

I would also be interested in a loopback plug: SM-B-916000.

Yes, I've considered constructing my own, but the manual's diagram of the
pins has differed slightly from the data port on my machine, which may be a
misprint. I know I'll eventually resort to experimenting with my own if I
can't source an original.

Surplus shops wanted $150 for the power cable. That was enough to get me to
construct my own for less than $20 including the hard to find Amphenol
connector.

Thanks much.
