Is there some reason why a digital signal cannot be passed thru an
analog/linear transponder? What goes in is what comes out. It seems the lack
of transponder bandwidth limits the digital signal experimenter...
Maybe that is why commercial transponders on satellites are linear. They can
take any modulation and retransmit it : AM, FM, PM or CB
The biggest problem would be the taxi-cabs etc

Are FM repeater satellites what we all want in orbit? No. Personally,
I'd like a Mode J linear transponder in a sun synchronous circular
orbit of about 2,000km (if we can't get anything to HEO).
Getting a launch opportunity is difficult and expensive. Going digital
is not.
