The locals probably don't like gold plating very well, because cheap
gold plate has less than half gold with other stuff to keep it hard but
that oxidizes. Pure gold plate is often only a few molecules thick
(measured in millionths of an inch) and is very soft which makes it wear
badly in a connector. The gold PL-259 I've seen were just gold on the
center pin. That's never been a hard solder job, its soldering the braid
to the outer that is the pain.

My local engineering team tells me the gold are easy to solder to, but
that gold is not the best conductor for connectors. These are retired
aerospace radio engineers who developed radar and radio controlled
drones for the air force, and numerous cockpit instruments for space and

I thought the inherent value of gold was that it does not "oxidize" or
"rust," per se... so I figured gold would be a great connector plating
material. The audio industry sells us on that notion... But the local
guys disagree.
Just MY take, anyway...

Any benefit going to the "Gold Plated" 259's? I think it would be an
excellent surface to solder too.
