I had the exact same problem as yours.  I discoverd that my 106B had a
6-channel board in it vs. the 8-channel that is supposed to be in there.
I put a 8-channel board in and the fault and GPS lights went out.

Over the weekend I left the XO unit running for 38 hours, with it
installed
in its "house"  (No probing).  The GPS receiver was tracking satellites at
the start and also at the end of the run as verified by monitoring J5-2
w/VisualGPS.  The Fault & No GPS LEDs never went out.  I'm about to
conclude
that I have a defective unit and will order another unless anyone has any
further suggestions (PLEASE)?

I see at least John A., Jim M., & Phil S. have working XO units.  I have
just reviewed all the emails on the RFTG units and believe I have tried
all
the previous suggestions.  Any additional secrets to share???

Bob Martinson, N1VQR

Briefly:
Leave it running for at least 24hrs.
The 15MHz will slowly get on freq.
Countup is available on 1pps socket.
more when I have time

Those who maintain that its OK to use 75 ohm GPS antenna cable should read:
