Just to add to this, encoding is EXACTLY what I wish to do. It may or may not include encryption as a part of the encoding, that will be configurable, such that a non-encrypting encoding stack can be built/used in Amateur Radio, while an encoding->encrypting stack can be built/used with MARS. Is this not SDR? From what Nigel said, SDR may be defining the carrier/modulation settings, is it so? Well, perhaps, whatever the software encoding solution within the realm of Radio, that's what I am interested in.

Kindly,
Robert

Be careful saying 'encrypting' in an Amateur Radio context.  Encoding is okay, encrypting not so much.
