Don:
I had to do the exact same thing on the XG1 I built last week.  Great little
device!

It is possible for the ridge on the bottom of the crystal can to touch one
or both of the crystal pads shorting out the crystal if it happens to touch
the inside pad. I had to lift the crystal about 1/32 inch off of the board

  Hi Gang,

  Any experience with the XG1?   What a simple circuit board and it's not
  working.

  If the xtal is mounted per the picture on page 6 of the instructions and
  where the instructions say to ground the xtal case into one of the square
  holes near BT1, then this all seems not very correct.  Either that or my
  xtal has the nomenclature printed in reverse on the xtal case.

  Anyway, I solder the xtal leads into the square holes right there where it
  says X1 and ground the case via a ground plane hole near the on-off
switch.
  The green led will light up and there's 1.22 volts on C3, yet there's no
  signal into the receiver or into the MFJ frequency counter.  This is at 1
uV
  or 50 uV.   All tests confirm the correct voltages where noted.

  In the initial test section page 3:   Step 1. says set S1 to OFF and set
S2
  to 1 uV position.
  Then Step 2. says set S2 to 50 uV position.  What?

  Any ideas?

  73, Joe, aa4nn
