[Elecraft] DeoxIt and/or ProGold useage

[Ron D'Eau Claire]

Good question Ruchan and I, too, was watching for answers.

I understand some fabricators do use it as a "preventative", but I don't
know why: are they using a substandard connector material that needs the
help or is there some other reason? 

I did not use DeOxit on my K3 or any other rig. I haven't used as a
preventative in the thousands of electronic devices I've serviced over the
years including a great many in very nasty environments (salt water on large
ships, etc.). 

One thing anyone who still uses a mechanical CW key has learned is that
modern logic, using the tiniest of signaling currents, demands
low-resistance contacts to work reliably. That's why I do use DeOxit on the
brass contacts of my Bug. Otherwise, the rig doesn't reliably recognize the
contact closure with even a small buildup of oxidation on the contacts. 

In theory, properly-mated electrical connectors exclude air, and so oxygen,
from the mating surfaces: they pins and sockets are in intimate contact
forming an air-tight shield over at least a significant part of their
surfaces for as long as they are in that position. They have essentially as
good a contact as if the connectors were soldered. 

That's exactly what the contacts on my Bug do *not* have. They spend most of
the time exposed to oxidizing air. Mated connectors do not. Also, the Bug
contacts bump only gently. There's no significant wiping action to remove
oxidation from them. Connectors literally scrape the contact surfaces clean
when they are assembled. 

So I keep my DeOxit handy for my manual keys and other contacts that manage
to acquire a layer of oxidation that impairs their action, and I leave it
out of new equipment.

Hi,

I would like to know if it is really necessary to use DeoxIt or ProGold 
product during the K3 (or any Elecraft products) assembling procedure or 
not?

Any answer from Elecraft crew would be apreciated.
