Its actually at 19200 bps, and its a data modem with proprietary
synchronization protocols (it is an off the shelf data modem, the company
wouldn't even let us know what all those settings were). To our knowledge
a unit of similar type is needed for decoding.
If you can receive the beacon (a 5 second burst that initiates on a 1/20Hz
repetition cycle) we would love to hear about it. It appears Bevo and
AggieSat are stuck together right now. We are looking for aliveness
confirmation until we can get the units in a stable state.
We have had one contact ourselves, and a few from amateurs reported that
show it is alive, but maybe weak. If you can give similar confirmation with
times it would be great to help aid us to get the satellites in a stable
configuration.
