Certainly to be considered...

Drew, would it be possible that if you are able command it back on an ad-hoc
basis it could be commanded into L/V mode for those sessions? There are
plenty of U/V opportunities up there for anyone already.

Thanks

I've mostly been posting about it on Twitter.

AO-92 has a cell that's failing, and towards the end of many eclipses it
goes into auto-safe mode at 3.6v. If the battery drops low enough the IHU
resets, and it comes back up in normal safe mode. Mark and I have been
commanding to repeater mode on the first available pass after the resets,
but it's not a long term sustainable answer. Last night Mark commanded the
transmitter completely off while we consider a plan of action.

Leaving autosafe on and the tx off, we may be able to turn the repeater on
ad-hoc for weekends or such, completely dependent on command station
availability. Turning autosafe and the IHU off like we did with AO-85 will
kill the satellite pretty quickly, so that's not a good response either. So,
we'll look at resets and battery states before this weekend and see where we
stand.

I can find no information about AO-92 going silent recently.   Was it
commanded into a silent state (as AO-85 was shortly before it went silent
permanently)?
