[Elecraft] K2 alignment after removing X2 (Logic Check?)

[John Buck]

I have not checked this out yet but I wonder if the change is necessary 
or desirable if the original crystals have the narrower swing capability 
stated below.  Perhaps this setup is more stable than the "updated" 
crystals with more swing capability.

Aloha,
