[Elecraft] Can't hear the internal birdie while in CW

Completed several mods including the 14 XTAL replacement and I can no
longer hear the internal birdie while in CW. Do hear it in either LSB or
USB. Where do I start looking for the problem? CW signals seem to be
much lower in CW mode then when hearing them in USB or LSB mode.

I'd check the xtals first and see if you have any continuity between the
cases and either lead on each crystal. In the initial build, a lot of
ops ran into very low signals that were traced to flowing a bit too much
solder into a crystal lead hole. It flowed through, formed a small bump
of solder around the lead under the crystal, and touched the case,
grounding the signal circuit at that point.

It's impossible to see since the short because it is hidden under the
crystal. 

That's assuming that the problem is in your crystal replacement. Your
situation is a textbook case for taking the time to reassemble the rig
enough to check it out after EACH change.
