Hello David,
I'm a complete beginner in this field, but after a lot of reading and
following these threads, I finally bought a Tbolt from China via
e-bay. Arrived in just under a week by post, plugged it in to power
and antenna and got 10 MHz output.
I eventually connected a lap-top PC via a USB-serial adaptor cable,
ran Tboltmon (downloadable from the Trimble site) (took longer to
find which COM port the thing was using) and got a nice display. The
unit was still showing its previous location as reference, so I just
used Tboltmon to reset to my location using the position data shown
by the Tbolt. Couldn't have been easier. I got mine from seller nhbbobb.
Regards.

I am not very much interested in how it is achieved, but wonder if a
10MHz oscillator locked to GPS is now available as "plug&play" rather
than needing a lot of time/effort/building.
I note the Thunderbolt units available from the Far East on ebay
for~?80gbp. Are these really P&P - that is, just connect PSU and
aerial and out comes 10MHz locked to GPS? Is it necessary to connect to
a computer via the RS232 link, or is that just there if you want to
fiddle and be clever?
If so, then this may be preferrable to running my rubidium source
continuously.
What I am interested in is stability, not ultiamte accuracy.
As always, sorry for the naivety of the question.
Thanks
David, G4YTL
