I agree with Bert.

I remember an issue with another OCXO where the output coupling capacitor connection failed and outputs were low.  Opening the OCXO and resoldering the connection returned the output to normal.  Morion I think.

I've never heard of this issue with the Trimble but not to say it couldn't happen.

Found a link.

Good luck.

Do not toss, first check output of OCXO if good keep if you do not fiend the problem. If no output replace. If L H shows that it works bring OCXO output directly.Bert Kehren

all the Alarms are Green and it shows Tracking 3 or 4 Satellites (small Hockey Puck Antenna).


Without a schematic I am lost as to where to look.


Anyone have any suggestions ? I had to toss an otherwise working T-Bolt.


Thanks for any assistance,


Dick, W1KSZ
