David and the BB,
There is a published schedule that says that L/U is subject to interruption
for telemetry collection.
I sent out a note to the BB earlier today explaining the problem I am having
getting the satellite ready for this weekend.
The 22:30 pass only affected those in the eastern US, I don't plan on
changing L/U during the 00:00 pass that covers a larger area.
The only schedule I can give you is that I will work on the satellite until
I feel that it will give solid operation for this weekend, which I hope will
be in the next 24 hours.
