If that were true then it follows that the modulation currently used with Codec2 Digital Voice is not practical for HEO either.
Quite true. The new HEO proposal warned that their scheme is not a replacement for AO-13. When most of hear "HEO" we visualize each QSO with its own discrete frequency on a VFO. The new satellite guys visualize many error corrected digital signals up and down; perhaps a multiplexed method. The satellite will need some processing power for error correction up there as well.
Hams learning how to interface a codec with their rig is merely a stepping off place.
Sooner or later they'll write up their proposal. I hope to run it in the AMSAT Journal. Give them time to work on it.
