I would be surprised if any of the transponders on the geo stationary satellites can work on amateur frequencies althought some of the C band transponders might be fairly close.
Does any one know if the comercial transponders have any degree of frequency agility ?

There have been cases in the past, where Old commercial satellites have been assigned other light duties.
Example, a marginally functional satellite was assigned free telephone status for the remote island Pitcairn.
so it may be possible to find some other satellites that still have working transponders which are not good enough for profit but could still be used by hams. Example, if the sat was designed as a Geo sat and it's Fuel runs out, it will drift out of its parking space. The transponders still work but it can not be used since its Moving and its not in its assigned parking space.
we should not only check out the Geo Sats, but also Tumbling Iridium sats too.
Any one have contacts are Huges or one of the other satellite companies?
