[time-nuts] Holdover Perf POOR

[Pluess, Tobias]

Dear colleagues

I have Lady Heather running with a Oscilloquartz STAR4+ GPSDO.
It runs since a couple months and was always fine, however since a
couple days I notice that it reads "holdover perf POOR".
I don't understand why, because I have multiple GPSDOs running at the
same spot; even though each has its own antenna, they are all more or
less (with a couple centimeters distance) at the same place on the
roof top with the same amount of free sky view (almost the entire
sky).
I see that it currently seems like it lost some satellites, but even
last week, when it hat 6+ satellites with >40dB SNR, it showed
"holdover perf POOR".
Is there some sort of diagnostic possibility to see why my GPSDO has
these problems?

Has anybody ever experienced similar problems, is my GPSDO simply
broken? for how long do these Oscilloquartz STAR4+ normally last?

best
Tobias
