[Heathkit] Heathkit Digest, Vol 95, Issue 9
GARY HATTAWAY

Judging from the backchannel mail I've been getting, people are indeed passionate about whichever side of the Deoxit debate they are on. My intent here was only to give pause to someone who might otherwise take a can of brake cleaner to a pricey(or priceless) rig and unwittingly turn a minor issue into an impossible one. For those who are comfortable in gambling, my best wishes. I'll continue to use a product specifically designed for the task, one that has served me well for a very long time.
Cheers,
Gary

Personally, I use synthetic maiden oil whenever possible, but it's hard to
find. I find it to work the best. Now for areals, I prefer Dr. Van der
Graf Antenna Wax. As they say, "a little goes a long way" Too much left on
too long produces "antenna lock, and we all know what that can do to your
signal."

Carl -
Which is why I have always used the D100L with the needle applicator. It only takes a drop or two.
A 'heavy spray' of most ANY solvent, oil, butter, milk, etc. TRASH will screw up a LOT of things! :-)
Some people can break an anvil!

I have restored hundreds of vintage radios and other equipment over many years, and I have never had a problem with Deoxit.

I've been using it daily for almost three decades servicing all types of communications gear from broadcast to ham gear to land mobile radio to avionics and it has yet to cause me (or anyone I know) the sort of problems described in earlier posts. I've run into the same symptoms described, and heard the horror stories, but usually found a deeper issue with gear that was diagnosed as having "deoxit syndrone". Almost invariably, the switches, pots, relay contacts, etc were previously contaminated with or exposed to some other unsuitable solvent.?This is in no way meant to offend and I hope none is taken, but I know of many equipment manufacturers who specifically endorse the use of (and even supply) Caig products as service aids for their products, and none that would endorse the use of brake cleaner.

Ah, I "See the PROBLEM", Well first off my receivers are on a separate
antenna.
When I hear a station on a frequency I want to work, I turn on the
oscillator in the
transmitter, and zero beat the station I am listening to. All the
transmitters go into
a "Dummy Load" until the antenna is "tasked to it". No signals on the air,
NO
annoying whistles, or swishing, generated "On Air"!
I think that is a courtesy to the guys that are listening to the station
transmitting.
"Prior Planning" and all that. Of course I can only speak for my stations.
No
pops no squeals, just the sound of the transmitter, quieting their receiver,
when it is my turn to talk!
