Well I was told by an unreliable source that the military had to have their
Amphenol's manufactured in the USA but were sent to Mexico for packaging.
Whether that's true or not I cannot confirm. All I know is the ones I buy
are stamped in black lettering saying "Amphenol 83-1sp and below that is
74868 PL259 49190" and they can run around 4 bucks apiece depending on when
and where I get them.

If this is happening, I'd suspect 1) the connectors have gotten wet or
2) the are JUNK connectors. If they aren't labeled "Amphenol," they're JUNK.
