Oops! Just found a link that has some info on my question...

Wonder how this is done electrically (modulation, transponder frequencies, space diversity...)?

Some of those numbers are pretty impressive.

"Does anyone know what kind of downstream bandwidth one of these GTH Ku band satellites discussed here and elsewhere will provide?... How many transponders are there, and what kind of bandwidth, modulation and useful bitrate on each one?"

I don't know, off hand. But the ultimate answer to your question could also have to do with how many --and how narrow-- the spot beams are that they are capable of delivering. This would then tell you how many times the same frequency was reusable, thus providing you with a multiplier that you could factor against any individual coverage spot, or footprint. I'm assuming, of course, that GTH uses such a scheme. Although, they may have been allocated different frequencies for different geographic areas, but that wouldn't detract from their overall potential. Don't mind me. I'm just mindblasting now.
