[Elecraft] K2 noise

[Hans Johansson]

I have a problem with my K2. When I am listening to CW-signals
at my beatnote 700 Hz everything is OK. But when I tune to higher
or lower pitch it comes noise on the signal.It is more noticeable on
strong signals than on weak ones. I wonder if anyone have had this
problem and have any suggestions of solution or is it a shortcoming
of the K2 ? (Perhaps VCO noise). I have no transformer in the 
neighborhood of the K2.
