Seasons Greetings

Hello all 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. 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 -- Steve Shuff.

Welcome to time-nuts Steve. Like many gps boxes there may not be an update. But that may not matter. It depends on what your interest is. Even with the wnro many units still lock and correct the oscillator. Just the dates wrong. In that respect there is a great program that may help you. LadyHeather. Its free and seems to handle many gps receiver types.
