I have two Datum 9390-6000 GPS receivers that show the current year as being

Other than showing the wrong year, they work fine as a frequency standard,
etc.
Please let me know if anyone can help.
Thanks,

Rich,
We have two of these units on our telescopes. One was new enough to upgrade via
a free PROM from Symmetricom; the other was too old for them to be interested in
upgrading (other than selling us a new one, of course!).
So we're researching replacement possibilities and limping along with software
that substitutes the correct year into the data string.
