Wouxun KG-UV3D Plug Plate

Based on those measurements that suggest spacing the plugs at 11.5 mm on center, I tweaked that parameter in the source code there and printed another one, just like the other one. Actually, I printed four of the fool things this time:

With the plugs in the gluing fixture and the fixture in the vise, a ring of epoxy around the threaded sides holds them in place:

A trial fit in the Wouxun KG-UV3D shows that the jacks prefer the 11.2 mm spacing I measured on the Wouxun headset, but they’ll accept plugs on 11.5 mm centers. I don’t know if that’s a real specification difference, a manufacturing tolerance, or what.

FWIW, I’ve been using snippets of that cable forever, because it’s perfect for this application: two unshielded conductors and three more inside a braid, supple as a snake. It’s surplus, of course, with a gorgeous push-lock plug (and the jack!) on one end that must have cost a fortune… and which I’ll never to use for anything. Got two of them, just in case.

Mushing an epoxy putty turd on the top anchors everything in place and protects the wires:

In point of fact, the cable insulation isn’t anchored inside the blob and a minor tug could pull it loose. There will be a bit of slack at the case to allow for unlatching it from the radio, but the lashup will spend its entire life inside a snug pouch, so it shouldn’t come to any harm. We shall see.

    the cable is surplus, do you recall where you obtained it? thanks

      Haven’t a clue, as it’s been in the pile for, quite literally, decades: gorgeous wire that I’ve never seen the likes of again. If I did, I’d buy a case of the stuff.

      I knew it’d come in handy for something!
