I suspect it probably stops during eclipses. It's lost about seven days
in 63. That's probably around the total eclipse times.  At the present
time it's very stable at 81.36403 days slow.

In the past UO-11 also used to send stored ASCII bulletins
as well, but I think that capability of the satellite ended
when the spacecraft computer turned off. Anyone know
for sure?

AFAIK, the computer was used to control the diary schedule, which
enabled the satellite to capture and transmit many types of data,
including a text bulletin.  Before the computer switched off, it became
difficult to command the satellite to upload the bulletins.
