Kind of makes you wonder what would happen if there was a geo stationary amateur satellite that was easy to use.?? If pirates will hack military satellites then I doubt they would have any qualms about using an amateur satellite.??
Mark's original point is still a valid one and has not been addressed yet in this discussion. An amateur-built bent pipe transponder in geosynchronous orbit will be vulnerable to the same sort of unlicensed abuse that FLTSATCOM is experiencing, and we amateurs will not have the same ability to prosecute the offenders that the US military has. If we build such a system, how exactly do we protect it from this sort of abuse?

our amateur radio satellites have already been hijacked and there was nothing we could do. those cber's with modified radios, the over powered portable phones, and the taxis south of the border.

IMHO the issues you are referring to are probably not cases of deliberate hacking of the satellites, rather cases of illegal operations inadvertently interfering with amateur satellites. The FLTSATCOM case seems to involve pirates deliberately communicating via the satellites. In my view having pirates routinely communicating via amateur satellites would be a real problem for us. If the amateur community is ever in the position to launch a satellite that provides similar performance to one of the transponders on the FLTSATCOM birds then we should think about how access might be restricted to amateurs, or how the system could be designed in a way to make it un attractive for pirates. The FLTSATCOM case is probably a worst case (ie. a GEO sat that seems to use FM, supports the use of simple antennas, and works in frequency bands that are easy to acquire or modify equipment for.)
