Unfortunately the hardware on board isn't programmable. The shared antenna's are connected to very frequency specific bandpass filters that form the multiplexer, the frequency translators are fixed and if the HPA is a TWTA it is also very frequency dependent. By the time the commercial operators are done squeezing every last penny out of them, there isn't much left over to use anyway :)

I have also "wondered" if any of the older commercial surplus satellites can be "reprogrammed" for our use. I realized that idea is no doubt an over simplification. Today's speculation can be tomorrows reality.

I vote for Intelsat G-11 at 304.5 deg E. This is a Ku band only bird, however, the semi-retired Intelsat 805, which is co-located with this sat has a global C band beam with a downlink that extends into the amateur 9cm satellite band (3400-3410 MHz). I often wondered if Intelsat would consider "donating" a few Khz to AMSAT. We could then tie a single, commercially licensed uplink station via echolink and hear it on the 9cm downlink. At least it would be a reason for people to use the 9cm band before it's taken away for the latest mobile broadband gizmo.
