[time-nuts] DATUM 9390 Info wanted

I have several (I think 8 or 10) of the 9390 series receivers. They all work
off of 5 volt antennas, and I use an HP antenna with mine through a
splitter. Some use a Rubidium, some an OCXO and some a TCXO. Most of mine
have Rubidiums in them. Interestingly, you can typically purchase the whole
receiver for a lot less than just the Rubidium on ebay. Just about every one
of mine locked right on, after a short while, and displayed the proper time.
However, most of them displayed the wrong date of the year. So, for timing
and frequency purposes they work just fine. I believe only two of the lot
also displays the correct date. I bought them all from ebay, and, so, they
came from all over the country. I have no history on any of them. Regards -

I was curious if anyone could tell me a little bit more about the DATUM 9390
clocks. Primarly whether it uses a propatary antenna & whether it is
indeed gps based or loran or ?? Also if anyone has a manual available
that'd be cool.
