Dick, If only! So far as I am aware, nobody has ever come up with a service manual for any of the HP/Agilent/Symmetricom GPSGOs. I'd be very pleased to be proved wrong!
I have here an HP Z3801A, Symmetricom Z3815A, Chongho GPSR-A and Samsung GCRU-D, and nary a manual between them! As you are probably aware, the USER manual for the Z3801A and the Symmetricom 58503B are available on the web. 73, Murray ZL1BPU _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
