AO-27 Operation Behavior Question
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.

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.

Hi Bruce,
No, the telemetry dump at the end is the end of its scheduled transmit time. This also happens at the beginning too. Check out www.ao27.org for more info on the schedule.
