[amsat-bb] Digital Satellites Question

[Douglas Phelps]

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.
