[Elecraft] K2 L25 and L26

[David Pratt]

I have just read Mychael's comments about L25 & L26.

I appear to have missed the change in the Low-Pass Filter components 
when I upgraded my Revision A PCB to Revision B.  I see from the latest 
circuit diagram that the filter is labelled "40/60m".

What is the reason for the change in the filter components, and is the 
change recommended for the Revision A K2?

Thanks de David G4DMP
