Mark I tend to agree with you on Bob. But that said the 10811 crystal is a bit odd. Its actually a copper cylinder with a screw on top. I believe to insure correct even heat distribution. There are pix's of it on one of the sights. Maybe the crystal comes out of the copper. The 10811 used in the Z3801 is a bit different from standard 10811 in the tuning sensitivity and I may believe that stability of the steps. But thats a guess. Some of the sites mention this. My goal was to simply confirm the rest of the 3801 boards were good and it is. So I have a spare for my operating 3801. Though it seems to be doing a fair job as compared to a TBolt I am using as a reference.
I have messed with the bad 10811 checking caps, resitors, and temperature and its still 50 Hz low. May dive back into that though I have exhausted pretty much anything thats possible. Need to clean things up by a lot. Then go searching for the com ports stalls that sort of started this journey.
