[Elecraft] XG1 Crystal mounting

[Don Brown]

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
