1L20-3 tuner stuck?
This cavity has been constantly trying to tune itself for some time. I went in to open-loop tune it but noticed it had walked about 2.6 million steps away from where it was previously over the course of about a week. I tried walking it back all the way to that point and quite a lot further on the other side, but there's been no response from the cavity that might indicate tuner movement. Nothing on the diag screen (fig 3) seems to be amiss either. Is this tuner stuck?
Fig 1 shows that something(?) happened on 5 Feb over about an hour, where the tuner took took over a million steps.
