[Elecraft] noisy VFO's

[Joe K2UF]

I have only had my K3 since January but no noise.  I have mine set pretty
loose.  I wonder if you could turn the pad over.  If that stops the noise
maybe just replacing the pad would work.

Dale,

That describes the noise I hear as well.

Let me know if the oil treatment works.
