[Elecraft] Help - K2 Higher Noise Level with X1 Selected

[VK1OO]

Hi,

Another interesting problem with the K2.  I've noticed that when 
switching between the KSB2 filters, X1-X4, that there seems to be more 
background noise on X1. And there is a similar increase in S meter bars. 
On a quiet frequency with X1 selected, the S meter shows S8; X2-X4 show S2.
I'd certainly appreciate any suggestions about where to start 
troubleshooting this one.
