[Elecraft] K2 SSB latest crystals

[JIm Wilson]

I have just installed a set of the latest crystals and modified the circuit 
to the components that John Grebenkemper shows for a 2.2KHz passband.  The 
previous (revised) mod to flatten the cw basic filter has already been 
done. The result is a very nice response with good bandwidth and low ripple.

A question. Is there any benefit to be obtained by replacing the original 
CW filter crystals? And, are they the same as the SSB Crystals?
