Thanks to all for the tips. Don, kd4ndb, suggested the xtal case is touching a ground pad. And so it is!! Also, Bob, n6cm, sent a photo of his XG1 showing lettering on the xtal being upside down as in the figure in the manual on page 6. His xtal is a BOMAR whereas mine is a KOREA where the lettering is right side up. Thanks for all the help. 73, Joe, aa4nn
