Beware...
Initially I installed just one felt washer. After a short time I
noticed the tuning knob was binding against the plastic panel.
This can cause scratching of the surface.
I put the other washer in place and that gave sufficient spacing,
however when the knob was turned it made a rubbing

The K3 Assembly manual has called for only ONE washer to be installed

each VFO knob since at least last October (Rev

Errata sheet C-3, November 26, 2007
So, whats the deal now, my Rev C (Nov 15, 2007) manual said one felt washer
under the main knob.
The errata sheet that came with it, Rev C-3 Nov 26, 2007 item 5 had me
change that to Two felt washers.
Please advise

It's entirely a matter of personal preference, David. It all depends upon
the feel you like. I had two originally, but now have one. Perhaps I'm not
as critical (and I have not had any tendency for the knob to rub on the
bezel). Then again, I still have at best maybe five or six hours of
operating
I don't know Barry. I have no problem adjust the drag while keeping a
smooth and even rotation.

I also found the K3 to be a great performer in the tough condx this

I must quibble a bit about the tuning knob however. I find it just about
impossible to adjust it for slight damping without feeling asymmetric drag
against the felt washer. I can't get it
Regarding the Main VFO knob, when I finished my unit I
found I had a felt
washer left over. Re-read the instructions and found
I only installed one
washer...oops! However, my knob action is silky
smooth, spins freely and

it stops. That's
I'm glad I stirred the pot just a little because I forgot about that extra
mysterious felt washer that was left over from the kit build. For the heck

now. So, free spinners might prefer one felt washer, but dampers

I don't know whether this was deliberate. I sent an e-mail to Wayne
