[Icom] PW-1 SO-239 discoloration

Sun, 7 Apr 2002 10:23:53 -0000

Perhaps the discolored connectors are silver plated and the others are not?
When I was a kid (a long, long time ago) it was one of my chores to polish
the silver (knives, forks, etc) because it would discolor with time.

When obtaining connectors I insist on silver plated.  That's why I don't buy
them at Radio Shack.
