[EMD]

Hi Don,

I think I may have found the problem.  When I installed X1 I attached  
a ground to the top of the crystal.  I used the same technique when I  
installed X2 through 5.  After rereading the installation portion of  
the manual I read that the ground should be attached no more than  
3/16" from the bottom of the crystal.  Do you think this is the problem?

Thanks

Ed
