FW: [Elecraft] 4 MHz alignment

Thu Jul 18 15:56:01 2002

I am just following the procedure on page 57 of the K2 assembly manual.  Others on this reflector have mildly condemned the use of WWV since it is unrelated to the 4 
MHz frequency the VFO uses.  If WWV transmitted at 4 MHz your suggestion would work quite well.  As it is I need to adjust C22 for the best 4 MHz signal I can find.  Try 
this it works pretty well.  I am in the process of testing my results now.
