And, in a related question, wouldn't more proccessing demand more power from the batteries/solar panels? I know my PC cetainly draws a lot more power when the CPO is working hard. Just curiosity questions, I support digital, FM, and Linear satellites. If it were not for FM sats, I would never have gotten interested in satelites at all. The congestion on the FM sateliltes drove me to start using linear satellites.
