[Elecraft] K2 RF gain control triggers sloooow agc action ?

[Darwin, Keith]

Is it a noisy pot?  If you spin the RF gain knob back & forth a bunch of
times, then try your experiment again, does it give the same results?

Hi Folks,

Recently I have noticed that my K2 has developed a strange effect.

If I move (even very slightly) the rf gain control the audio silences
and the S meter shows full deflection. After about three seconds or so
the receiver recovers and the s meter returns to normal.  This happens
wherever teh rf gain control is positioned about it's axis.

My K2 is no 1926 and currently has the original af gain circuit. I do
have the Elecraft mod to cure the "noise" problem but it is not yet
fitted.

Any suggestions ?
