Alan,
If the RF gain pot is worn it will behave that way.
If this is a fairly new K2 I would say SN above 4000, the pot should
not be worn out yet unless the operator used it excessively - so in that
case, look for an unsoldered connection between the RF gain control and
the path to the K2 Control Board.

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.
Any suggestions ?

It was suggested the RF Gain pot might be noisy but the OP never
followed up. Is this most likely root cause? If so, can someone point
me towards a replacement 5K LIN pot that will fit, ideally sourced
from Newark (Farnell in the UK)?
Thanks a lot,
