My oh my,,,, what a bunch of guessin', whatifin', supposin' and dreamin' going on!
So SES3 has been held up in FCC approval for a year and a half primarily by DirecTV KA license claims and now your suggesting that it will be used by DirecTV in the US?
All I read is that SES3 is licensed to operate C/KU and station keeping. Industry Canada will decide if and/or what they will go with the KA band.
Dan, Satellite signals are analog carriers. These carriers can contain transport streams of digital data that can be any type of parameter created by the encoders and modulators.
