A friend of mine has two Motorola GPSDO's that I have little  experience
with.
I was checking one of the units using TAC32 and I discovered that it
would lock the 5 MHz
to GPS ( as compared with my Z3801) when the PC software was running
When I stopped
the TAC32 it would lose lock.

Anyone have a clue what this thing needs to stay locked..

The circuit board has a date of 1992 and it has a label that has
TRN7793818  LA081WN.
On the back it has connectors for;
48 Volt power
Redundancy Control
Remote GPS (10 pin)
RS232 DCE
1 PPS out
5 MHz out.
And an On Line LED

Amy place I can get more information?
