Paul,
I don't know if this will be of any help for your particular
situation, but several years ago I had a problem where my Spectracom
8170 would not lock. I checked and found that I had good, clean
signal at the input spigot and the voltage going to the antenna was
clean and correct. After being patient with him for plenty of time,
I finally broke down and called Spectracom and reached someone in
service. What he said to me was: "There's a board with 4
electrolytics on it. Change the electrolytics and he'll be
fine." (This is not the receiver board) I did and my 8170 started
working again. In fact, he was locking up and staying locked better
than he had in all his previous life with me. A few years later, and
for some reason that escapes me now, I shot-gunned the entire
receiver with new, high quality electrolytics. I do not use him as a
frequency standard, only for a fancy-shmancy clock.
As far as how well he keeps time these days; he agrees with my two
DATUM 9390-52054 receivers as best as my eyes jumping between the
three of them can see. By the way, speaking of my two 9390's, since
I replaced the Caritronics switching power supply module inside with
an external Cisco ADP-30RB, both are working fine and seem happy
around 1E-12 and a DAC of about 29000.

I don't know what to say at all but the bpsk signal does a number to my
8170. So all I can do is scratch my head. Lucky you.
Regards
Paul.
