If ROS is Multi FSK now, than WHY and WHAT was the intent to call it (SS)
Spread Spectrum?, even as the FCC inplyed that the owner (Jose Albert
Nieto)called it (SS). As much as I would like to use it and knowing that the
FCC will not show up at my door, but they might send me a letter and ask me why
and to show cause why.
How that ROS has been labeled as SS, and all the others that might have use ROS
is standing back just not knowing what to do it best just to now do anything
yet.

In fact, ROS is a Multi FSK, like many other modes.

Asunto: AW: [digitalradio] The FCC's definition of Spread Spectrum
Bw lower as 3kc and fsk … like many other modes
That is what i think
So legal where 3kc wide/digital is legal so out of cw portion but in the
digiarea
Dg9bfc
Sigi
At a given time if you make a snapshot there is only one tone so bw at a given
short time in lower as 500hz
So it is narrow in a short period of time ;-) should be legal anywhere
My thoughts is all modes should be legal in any band cause hamradio is
experimental!

Betreff: [digitalradio] The FCC's definition of Spread Spectrum
Part 97.3 "Definitions" defines: "SS. Spread-spectrum emissions using
bandwidth-expansion modulation emissions having designators with A, C, D, F, G,
H, J or R as the first symbol; X as the second symbol; X as the third symbol. "
Title 47 Sec. 2.201 is the relevant section formally defining these symbols. It
can be found on the ARRL website.
For a signal to be officially considered Spread Spectrum by the FCC, it would
have to meet a very specific description, or maybe I should say it should not
meet the other specific definitions of emissions.
After my reading of 2.201, I don't think that ROS or Chip64 could be
"officially" defined as Spread Spectrum.
And, the response from the FCC doesn't provide any FCC position or
interpretation of ROS, and further says "The Commission does not determine if a
particular mode "truly" represents spread spectrum as it is defined in the
rules."
Just my thoughts,
