Please accept my apologies as this post is not strictly EW.
I have been lucky enough to have been given a few "GPS800 Satellite Synchronised Time & Frequency Standard" units complete with aerials, and all in working order. Manufactured by Timecode Clocks.
These units suffer from the WNRO issue and I am wondering if a firmware upgrade is available to combat this issue.
I have trawled the www for information on these units but to no avail.
Would anyone on this mailing list have any information, service manuals etc on these units please.
Thanks and
Seasons Greetings
