K3 VFO converter/Knob

[Claude Du Berger]

Hello group
Is it normal while turning the Main VFO Knob I hear
some noise like friction?  no there is not too much friction.
I dont hear such noise on my old IC-746

Yes.

The K3 uses a fiber disk to provide the friction.  The result is a
slight bit of noise as the knob rotates along the disk.  I've read
suggestions to use various other materials including felt.  When the
AF is up I don't even notice it.

One advantage of assembling the K3 from a kit is that you learn how it is built mechanically, which is often useful.  Assembly is really easy, though I recommend buying a nice, new number 0 Phillips screwdriver.

I got the same issue and mine is a factory build. Doesn't seem to be hurting anything, however.

What "fiber"?  Mine was a kit and the material was definitely felt washers (2 in the kit).

I could never get the feel I wanted and didn't like the sound either. I replaced the washers with a single, larger homemade felt washer that just fits the recess in the knob and is glued in, so there is only one sliding surface. Just a tiny swish now and acceptable feel, hopefully without too much loading on the bearing(s) in the shaft encoder.

Well, I removed the knob and the felt washer... and just turning
the shaft with my fingers I can hear the friction noise. Of course that
is with the RX muted, computer off in a quiet shack. Maybe I have
a bad encoder...
