Let me address this by asking one simple question. What would happen if an entire satellite does go out?
Where would they put the stations that were carried on that bird? Hopefully they have extra transponders on another bird they can use...
As I said a backup satellite will be needed to take its place, and light up the TPs on the backup satellite that occupy the same frequencies the lost bird used. Once a bird is gone, the frequencies used by it are no longer used by it, and are taking over by the backup bird, again no need to have any unused frequencies to fill the void or as temporary go between.
There are and always have been unused spare TP's on D10, yet when there were a lot of games being shown on their sports packages they would remove programming from a PPV channel or two because of the extra bandwidth need. I think it was more logical to conclude that there was no more bandwidth as opposed to no more stations to add???
Hemi's question is I think, why leave unused frequencies that D* already have license to use? He just asked it in a wrong way.
The only reason is there are no more stations to add. Another reason could be there were only so many working TPs left on the bird, if so the backup bird would cetainly kick in to use the unused frequencies. But that is hardly the case here.
