Hi
At that time (and today) a 3801 is a “well over $300” sort of box at auction.
The REF-0 box hovers between $25 and $40 depending on
the direction the wind is blowing. Cost does matter …. What makes sense on a
$800 gizmo probably does not make sense on a $80 stitch
up project.
Yes you cou
Only the first oscillator in your list is voltage controllable (VC). If you
want to steer it with a GPS as we have been discussing, it needs to be
voltage controllable.
You will also want to consider the mounting and whether you are able to
solder surface mount devices like the second one in your
Hi John:
It seems like the indoor improvement over GPS is based on the much stronger
signal level of the Iridium signal.
Note the two signals are both in the 1.6 Ghz area.
Page 15 of this document says the BOM cost is under $20 for this service (no
mention about the monthly subscription).

Synergy GPS makes an SSR-6Tr board that speaks Motorola binary and would
probably work in the KS-24361. It's on an M12+ sized board, so you'd also need
their adapter board to fit it in. Their SSR-M8T board would probably do the
same thing but using an LEA-M8T receiver. I believe they're selli
I’m working on a project that needs a good clocking source deep inside
of noisy environments (data centers and the like.) This can’t be
network-based - it needs to be independent of the systems surrounding
it, and GPS/GPS-like systems will often be unreachable. I’ve read up
a bit on Iridium
I went back to the Time-Nuts archives, and noted that a modern GPS receiver to
replace the Motorola Oncore UT+ (8-channel, timing) in the HP Z3801A was
discussed 3 years ago (Sept, 2012).

a quote from goledge.com and their prices are around 180GBP per unit, and I
dont want to pay that much given you can buy a rubidium standard for
comparable prices.
I looked on ebay and found those candidates:
