The plugs/jacks are meant to be connected
all the time, so it is better to just leave
them connected. I believe the usual culprit
is a break in the little wires inside the
cable, and not usually the spring clips that
comprise the jack. They usually break close to
where the strain relieve ends. One can usually
repair them by cutting the jack off the cable
(NO pun intended... I assure you) ;-)
and installing an inexpensive replacement for
around $1. The same goes for the plugs on the
headphones, although the little cables on the
headphones are typically much smaller gauge than
that of the extension cable inner conductors, so
they are much harder to fix than extension cables.
I have no argument with the suggested de-oxit
treatment, but in my experience, the jack is
not the usual suspect (although sometimes the
jack contacts do break occasionally) and the
usual problem is a break down the line just
after beyond the strain relief, so close to
the jack we suspect it, instead of the cable.
Shoot, these little extension cables cost
about $2 or less at www.allelectronics.com
so it behooves one to have several extras
on hand and just toss them when they go flaky.
I cannibalize them for the good ends and use
them for other things when building projects.
I took extra cables, an extra headset, and
some odd connectors to my first time at the
big contest station along with my radio and
favorite headset - just in case I encountered
any problems with my gear... and that enabled
me to provide instant replacement of a
flaky cable and headset on the most important
40 meter station, saving them from having to
effect time-consuming repairs. I felt pretty
stud because I was prepared and was able to
solve the problem in a flash.
So, buy extra cables and just swap them out
whenever they go bad, tossing the good ends
into your "wish box" for use in future building
projects.
Just MY take, anyway.
