Interesting post on the DeOxit...... I just got a bug and was told,
"They're not as good as modern keyers, they truncate their dits". But
maybe some DeOxit and paper burnishing will change this. Thanks for
the info, 73 de Alex NS6Y

I'm one of those who has used DeOxit on some old keys - two "bugs"
from the
1950's that see regular service on my operating desk.
I was having to constantly "buff" the contacts. I used bit of
paper, drawing
it through the contacts while holding them closed several times. If
I didn't
use a particular key for several days, it'd be needing a considerable
cleaning. Even when in constant use, I'd have to do a cleaning
every week or
so. Keep in mind that the contact closure is far more critical on a
bug than
it is on paddles. If the logic sees a contact closure when using a
keyer,
it'll make a dot or dash of exactly the correct length. With a bug,
that dot
or dash length is totally dependent upon the rig seeing a good, stable
contact closure for exactly the right length of time. If the
contact is
dirty, the element will be truncated. The sending is often
described as
"scratchy" with the carrier jumping on and off perhaps several
times in the
length of one dash at 20 wpm as the keying circuit interprets the poor
contact is alternately an open or closed circuit. It really makes
for nasty
sending.
One day I was launching into yet another cleaning and saw, right
next to my
key, a little squeeze bottle of Caig DeOxit. So I put a small drop
on the
contacts. The surface tension held it in place with the contacts
open. A few
minutes later I tried the key. Perfect contact action. I did have
to remove
the excess DeOxit from the dot contacts since the liquid interfered
with the
smooth action of the pendulum that makes dots on a bug. So all that
was left
was the very thin film of DeOxit that clung to the metal. It was
more than
six months later that I noticed the contacts needing help. Before I
had to
clean them ever few days. I now keep a little squeeze bottle of
DeOxit at
the operating desk <G>.

Yes. It's fantastic for virtually all contacts and pots.

Dave-
I bought a Graciella at Dayton so am very interested in this
thread. Are
you talking about Caig Deoxit or something else?

I put the stuff on my keys a couple of years ago and haven't had any
problems since. I think it will last indefinitely. I learned about
the stuff on this reflector, so I suspect there are those with even
longer experience who may want to chime in.
best wishes,

Hi David,
How long will the Deoxit treatment last?
Thanks,

A tenth-drop of Deoxit on the contacts will produce the same effect
with no abrasion at all. best wishes,
