Agreed - I would say that innovation is proceeding faster than at any time
during the 35 years since I was first licenced to create QRM on 160m.

For those USA hams that are using ROS on HF, I assume that by using
it...they feel it is not spread spectrum and thus should be legal. Is there
any movement towards petitioning the FCC to reconsider the unofficial
comments by them and obtaining statements that it is legal ? Or has

Andy,
I have been told by a FCC engineer, part of the evaluation group at the
FCC, whom I will not name, that ROS 16 baud and 1 baud has been
evaluated in the lab and is spread-spectrum and therefore illegal on
HF, not only because the author first said it was spread spectrum and
then
No, the problem is that the spread spectrum variants are mixed in with
the others, all inside the ROS program, so any overall approval of ROS,
which undiniably includes the non spread-spectrum modes, would
accidentally approve the spread-spectrum modes also. I'm sure that the
FCC is not that

Both these QSO's were on JT. On 18 April we had a long test with

some use on 144 EME. We saw one good decode from Rex in ROS.

Thanks. I get it.
Not all those US calls are fake though.

I'm all for itI've been anti-ROS since I read the Spread Spectrum
description in the original documentation.
My point, and Siegfried's as well, is that you can't say that a whole

think that is fairly supportive of all

It was not my idea. The author wanted the FCC to say it was not spread

Unless there is spread spectrum in ROS you cannot use it. Of course, you
can use the part that is not spread spectrum, but the FCC is not going
to issue a blanket approval for ROS if any part of it is spread

anyway. They just
Spread spectrum is where, functionally equivalent to the to the randomizer, a
