[Elecraft] K2 L25 and L26

[Don Brown]

Hi

The change was made to allow for 60 meters. If you add the K60XV you will need to change the filter.

  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
