IMHO it is going to be really difficult to draw a line here for digi
modes. What is the definition of single channel? What passband is narrow
enough? What about SO2R or 3R or even more R? Can one use several different
decoders within one passband just because different algorithms behave
differently under different propagation conditions? Will that be counted as
assistance?
I think that the definition of unassisted should continue to be linked to
the number of operators involved. If single person uses all the hardware and
does not get assistance from other humans in "locating and identifying" -
that is unassisted.
