[Elecraft] Noisy RF gain pot?

[Don Wilhelm]

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.
