[Elecraft] PLL Reference Oscillator out of spec

[John, KI6WX]

Mike;
That is way out of spec.  Make sure you all of the components installed in 
the correct location.  Double check that you go the varactor diodes in the 
right location; this circuit uses two different types.  Also check the DC 
voltage on the varactor diodes to make sure it varies from 0 to 8 volts.  If 
everything checks out okay, ask Gary to send you a new crystal and check 
that one out.
