I'm with you, Skip. While I appreciate the effort Jose put into this mode, I won't be using it on HF.
The article quoted as justification of the legality of ROS was written by the Italian developer of Chip64 who is not under the jurisdiction of the FCC. The ARRL lists it only as a technical reference to the mode. Since the ARRL is NOT the regulatory agency, it really only matters what shows up in Part 97; and under Part 97, Chip64 is also illegal on HF in the US.
