Re: re: multichannel satellites?



If they mix each of the multiple receiver's audio together then all
stations will be heard at the same time - I doubt that's the desired
effect.

Multiple FM receivers would be useful for multiplexing digital voice/data
and/or even analog voice/data into a single digital DataStream - then it
could be sent down on the TX as digital to be decoded by the intended
recipient(s).
