[Elecraft] Picked up used K2

[Mike Bellow]

I just picked up a used K2 and have been checking it out.I think I found 
2 issues with the radio,Receive on 15m,12m,10m is fine sounds good seems 
to be right on.On 17m and 20m the receive audio is very sharp not like 
the other higher bands,My question is where do I start to get these two 
bands back inline correctly?This is my first Elecraft and am very 
impressed with it's operation,I actually like the rec better than my new 
Ft-950.

tnx Mike W2TI
