It is silver sulfide {tarnish} which is semiconductor and will therefore
conduct electricity, but will reduce the surface conductivity. To what
extent will depend on the thickness of the tarnish. Surface tarnish
will not affect bulk conductivity unless the "bulk" thickness is very
thin.

I wonder if anyone might have a Norcal 40a Designed by Wayne Burdick

Some of these are disengaged purposely. And no, I don't live in a corrosive

The TMP connectors should never need cleaning unless they have been
contaminated (usually by body oil from handling) as they are silver plated.
Don’t handle the contact areas of the male plug, as once oil is on the plug it
will transfer to the jack on the board, potentially causing connection
Both rigs have found new homes so now my XYL can’t argue too much about a new
K4 (or two).
I’ll have fully loaded S/N 4933 for sale in December after my first K4 arrives
if anyone is interested. It is loaded essentially the same as #752 below but
obviously newer.
Thanks,

I always used a pencil eraser, worked great. On old Stromberg Carlson Switch
gear to clean the contacts I used a $100 bill. Not much grease on them. Hi

When I install TMP cables in hard-to-reach
locations I use hemostats, the ones with
the knurled teeth. Of course never clamp
down on the connector, keep it with the
loosest possible grip so as not to deform
anything.

These cables, like many cables with connectors will accrue connector
oxidation. Often the oxidation is such that it prevents a very low
level signal from passing. The solution for many instances is simply
to clean connectors.
My approach is to use a Q-Tip, apply your favorite contact
i have never had a problem with TMP cables themselves. They’ve been in and out
of my K3 many times doing upgrades, etc. I HAVE had a problem with my own
careless installation.
In some socket locations you have to be careful. You can’t just jam the plug
in the socket when you feel
I have had similar problems with the TMP cables. Was tempted to just replace
all of them, but everything seems to be working great now!

What is the part number of that carefully chosen TI chip? Various versions of
the PCM2903 are used in amateur radio equipment. Did Elecraft use something
better in the K3S?

If available at this early stage, any specs on the upcoming K4 sound card,
or likewise, its internal chip model number, would be of interest here.
Perhaps it will be the same as the carefully chosen TI chip used in the
K3-S. Thank you.
Hi Gary could you perhaps chose 2 transverters 144MHz and 145MHz and set the
levels accordingly? Fortunately all my transverters have a 28MHz IF. Another
Elecraft 'surprise'. The worst one for me is the K3S TX IMD on 6m, its really
quite awful and not good enough for me to use. So I suppose
