The pcb 05245-60033 was part of the mod kit for upgrading 5245L and
5248L counters to put a 10811-60105 in place of the original 5243A-69A
1 MHz oscillator. Hence the times 10 divider on the pcb.
The mod kit itself was part numbered 05245-60038. I have the details
and can scan them if necessar

Hi Tom,
how many M12M iLotus samples did you test to find the one with 30ns

How did the other ones perform?

Hi folks.
Anyone have the specs for HP 10811-60105 OCXO?It is not listed in the
Mejia-Norton document. It was supposedly removed from a 5245.
I'm also looking for a schematic for the aux board/assembly p/n 05245-60033,
also supposedly from a 5245. It has a rectifier, video amp and de
Thanks Rob, I did find a picture under their Cellular stuff that looked
exactly like one of the RFG units, so I sent an email. If I hear back I'll
let everyone know.
In the mean time I came across some pictures that appears to be a RFTG-XO
that has been taken apart.

Hi Bruce,
I forgot to say that I'm fairly certain that the interface is NOT NMEA.
It's fairly easy to monitor on the main PCB.
If I remember correctly I had to do a cold start or reset before it
would acquire any satellites. I'd have to look through the menu options
to be sure.

Hi, Robert,
Thanks much! This is good information. I feel fortunate to have gotten
one with the Magellan module.
What I'm planning on doing (Since Zyfer doesn't seem to even care about
these grand old beasties any more) is reading all the EPROMs, and any PALs that
are in the un
Hi Bruce and Doug,
I have three SatSync 325 receivers. Two have the original Odetics rx,
one has the retrofit Magellen OEM rx. Two have OCXO's and one an Rb
oscillator. The one with the Rb has all the interfaces fitted including
HaveQuick timing, unfortunately it has the Odetics rx. The Odetics rx
All,
The paper has not been written yet. It will be up as soon as it is.
The smaller PDF version of the presentation slides is now up on the site.
Just go to www.gpstime.com and get what you want from there.

Since the question was:

one should mention that it is NOT cold Rb that is excited. Instead, the
whole of the resonator is heated up to give the lamp housing a
temperature of 113+/-2 degree centigrade (FRK-L maintainance manual).

Efratom bought by Ball and then sold to Datum. Datum bought by Symmetricom.
All units from the same pedigree. AFIK Gerhard Hubner one of the
co-designers of the first units still running things for Symmetricom in his
office south of Munich.
