You mentioned Time Server..is this your only GPS or do you have other more
accurate timing requirements? Unless you are working on nanosecond type
accuracy, I don't see that mounting your antenna on the metal roof is going
to cause you any practical
Matthew,
You hit the nail on the head with item 4!
Good luck.

I am trying to find a 100 MHz VCTCXO. The term VCTCXO doesn't seem to
be universal, so what I mean is a crystal oscillator which is voltage
tunable, but which without tuning is within about 10 or 20 ppm. Rakon
has parts on their website which fit the bill, but they don't seem to
actually make

Hi to you all
Some short while ago I ask for help/info on the Odetics 325 - the main problem
was that I obtained mine without antenna - well I have received considerable
help from a number of members, and in particular from Rob - who solved the
antenna problem. My old 325 is now up and running
Hi everybody;
I just got a Motorola Oncore+ GPS receiver for use with a disciplined
Frequency standard I'm building and was wondering if anyone could tell me
if it will be useful for this purpose.
The part number is R5122U1154. I know it's a bit late to ask this
question after the purchase

Rex,
Thank you for your input.

Other people clearly have units that run on just +15V and do respond
to
serial commands to set the frequency. One person reported they were
able
to adjust the frequency on theirs with a screw
I think that I might purchase a GPS disciplined oscillator instead of
rubidium standard for a cal lab. There's no physics package in danger
of wearing out and no worries about local settings changing accuracy.
They are also low power and something like the Trimble unit is very compact.

I happen to be looking for a source myself for a 110MHz VCXO
with 150 to 200ppm pullability, I came across Mtron-PTI
who offer TCXO's, TCVCXO's, VCTCXO's and VCXO's.

Jean-Christophe,
Someone else may know better than I, but some (indeed most?) of these
units on eBay do not have a 10 MHz output, only
12 matches
