At first glance, I can not see any significant differences in the 
reception quality of both modes.
But, the possibility of a phase correction is a useful feature in the 
case of THOR22.
The pattern looks like an 18-tone MFSK method.
Perhaps there are advantages with weaker signals or with Doppler 
disturbances.
The future will show it, hopefully.


"Lesson 16"  with a new digital mode, which means:  big picture to count 
the audio tracks. ;-)
