Thanks Skip,
Unfortunately, this really does not get to the crux of my question(s). I
understand how an SSB transmitter works, but that is not really what I am after.
What I am driving at is if like this. If I use DM780 to run some version of
digital mode via an SSB transceiver, it uses a tone
It will be spread spectrum if the tone frequencies are controlled by a
code as explained in the ROS documentation:
A system is defined to be a spread-spectrum system if it fulfills the
following requirements:
1. The signal occupies a bandwidth much in excess of the minimum
bandwidth necessary

The only entity competent to answer the question is the FCC, and the
accepted procedure when one is not sure is to ask for a clarification.
Unfortunately, it is everyone's legal responsibility to understand the
law and obey it. Since most of use cannot do that, we have to turn to
lawyers to do

Gentlemen,
I have spent way too much time with my limited knowledge trying to make
some sense of this issue and answer questions. I am going to use ROS on
UHF only anyway, and it is legal there no matter if it is FHSS or not,
so I'll leave it to the rest of you to discuss the issue.
Thanks

No, the shift on RTTY and other soundcard modes is not determined by a
pseudo random code but always known and predictable. Instead, the tones
on ROS are driven by a code signal. To quote from the ROS documentation,

I think you make the same point as I am seeking
Just because the author of the program calls his great work spread spectrum
does not necessarily make it so. Sorry Jose
Here is partially why I ask for better clarification
