Maybe a general "band plan" for all the SATs will be a solution......
I think this is an excellent idea, given the proliferation of modes which are now available.
Guidelines such as these should take into account the benefit of forward error correction (FEC) coding on required uplink signal power _at the satellite_.
This is to say that less received power (transmitter power + antenna gain - path loss) can be used by stations employing FEC-coded protocols. This will reduce the overall load on the transponder.
In essence, a bit more power burned by your 20-core PC on the ground to encode/decode results in better power usage for everyone at the satellite!
