Hi,
I purchased a pair of L105A & L106A units from you (via Ebay) a month or so
ago. I understand you also have the mounting frame (or chassis) for them,
are these listed on Ebay?? If the price is right, I might be infested in
buying one frame with the interconnecting cables, please specify if t
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.

While I provided the quote from the Thunderbolt manual that said, according
to Trimble, that 75Z coax is fine, I have Times LMR-4
Hi All;
I'll give my experiences with my RFTG unit. I bought it ($$$) last fall from an
ebay seller who moves a lot of time and frequency related items, it won't take
much imagination to figure out who I'm speaking of. I believe he is an honest
seller, and I've bought from him several times and

Perhaps they can, perhaps they can't, but why not prove them in their
intended configuration before attempting to use a non-
Thanks for the quick responses, Jim & Phil!
No, I was running the XO unit all by itself. My guess is that the XO should
be able to run all by itself??? I have previously run with the XO & the RB
interconnected (J5 & 10 MHz Ref). Not for 24 hours, but at least over
night, but No GPS stayed ON o

Did you have the RB connected via the crossover cable and 10 MHz
cable as described in previous emails?

For those who would like to improve the phase noise of the output of a
digital divider or who would like a good reason to using DDS instead see:

This is very interesting, indeed, and a very nice practical, follow-on work
from the theory paper by Audoin et al.
It wasn't clear to me how muc
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

You can potentially drop the Allan deviation of a rubidium package by a
factor of ten using the modification detailed in the paper.
