AO-27's schedule basically works as follows: when it turns on it transmits roughly 30 seconds of data, activates the repeater for 7 or so minutes, then another 90 seconds of data before shutting off. If it appears to be dead afterwords (ie you can't hear yourself on the bird with a 2nd radio or in full duplex) then you caught it on the tail end of the schedule. Goto AO27.org for the current schedule or download the Scheduler at http://sites.google.com/site/ao27satellitescheduler/ and generate your own schedule predictions.

Is there some sort of IDLE / switch over / recovery time after AO-27 does it's telemetry dump before you can get back into the FM repeater?
I have strong signals S9+30+ going into the telemetry dump -- and then it appears to be dead after it finishes.
