Hi Tom,

Thank you for the link, I searched and searched but I got nowhere.

I haven’t played with my equipment in almost 15 years.  I need to get back into it.  For instance, you mentioned the heater.  One plug which goes to the power supply on the Z3805A has two wires disconnected.  I probably did that, or it came that way, I just don’t remember.  This unit used to work but not anymore.  Everything checks OK (status) except for the EFC.  On the Z3801A (my first GPSDO) I had taken it apart and put it back on frequency, but of course, the adjustment is with the oven taken apart down to the 10811 level.  I don’t know what the limits are, and certainly did not know where the EFC was or which way it will drift when re-assembled.  Currently both units show the EFC at the rails, so I am assuming for now, that the oscillators have drifter too far and they need a push back to the center.  I would like to convert these two paperweights back into working units.

My Trimble is working fine but I don’t know how long that will last.

I am off for three weeks, so all this effort will go on hold until I get back.

Thanks for your help, 

Bob
