Thank you, Steinar, but there have been serious attempts to dominate the
HF bands with wideband modes for what is basically a private system use,
and the FCC acted to protect the bands from that abuse, so while it is
sad for us right now, what the FCC has done in the past has protected
all hams worldwide from such abuses, even if you do not realize it. I do
think ROS should be allowed, but until fully reviewed by the FCC, their
are correct in not allowing ROS to be used except on an experimental
basis. Believe me, there are much more dangerous fish in the sea!

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.

Thank you for your opinion, but need to be told to "calm down" as I am not
excited! The FCC rules are plain and the description of ROS by the author is
frequency hopping, whether within a phone signal bandwidth or not, so that
identifies it as spread spectrum. I am sure the FCC rules were intended to
prevent overly wide signals on HF using spread spectrum and therefore they
only permit spread spectrum above 222 Mhz, where there is plenty of room.
ROS is a really nice mode, but I will be using it only on 432 Mhz, in
accordance with our FCC regulations. Others under FCC jurisdiction are
welcome to use it at their own risk on HF.
The current FCC rules are also probably intended to allow FCC monitoring
which is not possible with conventional spread spectrum, so I hope the rules
can be changed for spread spectrum modes like ROS which can be copied by
third parties, but until that happens, rules are rules, and we are legally
obligated to abide by them.

Ok calm down, que no panda el cunico como decia el chapulin, this mode is legal.
Read this and you will know why is an article of the ARRL
