Hello Jeff and BB,
You are correct that it would be good to have a specific time for the change over. That being said, I (and the other commnad stations) do the change over generally during the eastern US passes and close to the new UTC day. Things come up for me (and the other volunteer command stations) and I can't always do the mode changes when I plan to a week before. Most often the changeover occurs during one or both of the evening eastern US passes on the UTC date given in the schedule.

When AO-51 changes modes, what time is the change generally done? For example, the schedule says that AO-51 will start broadcasting 9600 baud telemetry on 3/10 (today).
Is this done in the morning on the east coast, is it preprogrammed to happen at some specific UTC time, or what? When are these changes actually made? It would be nice if the schedule announcement had some additional precision, something like: on orbit-xyz during the pass over the abc groundstation, the mode switch is planned.
thanks, jeff AD6EO
