GPSDO On 6700 Erratic

Just recently my 6700 started having occasional problems with the GPSDO not locking up. It would stay in "holdover" mode. The number of satellites visible seemed to vary rapidly, jumping from 15 to 6 and back in just seconds. Satellites tracked stuck at 99 which is obviously not a good sign.

Running SSDR v2.3.9.

Tonight, it appears to be a permanent situation.  Repeated power downs, removal of power and restarts and executing the "uninstall" then "reinstall" commands for the GPSDO have not changed the holdover status.

Searching the community site indicates this could be a bad antenna (has always been indoors), a bad GPSDO board, or an issue with the GPSDO board connections.

I intend to open up the radio tomorrow and try removing and reinstalling the GPSDO. Just wondering if there are any other suggestions?

Maybe it is time for trouble ticket and trip back to Texas?

Thanks for any suggestions.

73, Tom

    Have you done a complete “factory” reset? That will usually nail any weird software states. If you can pick up a replacement antenna (they’re pretty generic), I would try that before comsidering shipping it to the mothership. Opening a ticket is probably a good idea, too.

    All great suggestions! Another variable is a software problem found its way into the mix at 2.3.7. Try backing up to 2.1.33 and see if symptoms change. Typically what I’ve seen is the color of the power button does not indicate the true GPSDO status, yet it’s working correctly.
