My just built K3 also makes the same noise. It's the felt washer rubbing
against the back of the knob. I was tempted to push the washer down around
the nut against the front panel but, the manual isn't exactly clear as the
whether it should be applied this way. I laid the felt washer on top
My wife provided me with some smoother felt which I cut into washers.
It is a lot quieter than the horse hair felt washers supplied.

When I got my K3 kit sn 3840 new just about two years ago, I noticed the same
noise. I cannot hear that noise now, and the friction point is perfect for me,
with about .5 to .75 extra rotation on a firm spin. I wouldn't suggest putting
anything on that felt washer, it will break in. Jim WN8A
This would validate the fact that the gentleman I purchased it from said he
barely utilized the rig. Now an even bigger smile is on my face.

If there is not a felt washer between the VFO knob and the
panel, then that is your problem. I have never experienced
the noise that you describe after operating about 6
different K3s.

That's something entirely new, Natan, and not normal for a K3. The pad
between the knob and the front panel should be nothing but a soft felt
washer, virtually noiseless as the knob turns.
Is there anything else there?
If not, recommend that you drop an e-mail to K3support (at) Elecraft (dot)
My newly acquired K3 makes this VFO noise as well for the VFO A knob. It is
only annoying when I have the headphones off.

Recently, my VFOA knob got a little wobbly, and then it started dragging
heavily, only when turned clockwise. I took the knob off and discovered
that the top one of the two control nuts had worked loose entirely, and
the bottom one was loose. Tightened them back up and readjusted the
drag,
Hello Natan,
I can hear the same thing here. Decent high frequency hearing and a
reasonably quiet shack are prerequisites to hearing it though. It's a
'sh' sound that occurs as a result of the surface of the knob
dragging against the felt as the VFO knob is spun. I've considered
applying
Dale,
That describes the noise I hear as well.
Let me know if the oil treatment works.

You might try wrapping the felt, torroid-like, with Teflon pipe thread tape.
