Steinar, that is absolutely true, the spectrum belongs to everybody, but
the other side of the coin is that we need to "police" ourselves, and
that usually means moving around to better accomodate other users of the
spectrum, or by their moving also. This is how we arrive at bandplan
divisions of the legal spectrum allocations.
I have been monitoring ROS all day, and in this country, Olivia stations
cause as much trouble to ROS as ROS causes to Olivia. It all depends
upon the relative signal strengths as to which one decodes. I see many
ROS QSO's stopped by Olivia 32-1000 traffic on 14106.
Since the 1 baud mode is slow and probably going to be most useful on
VHF and UHF for weak signal DX or EME where S/N is a much greater
problem than it is on HF, it might be better to suggest moving the
recommended ROS 16 baud 20m frequency to 14109 to avoid collisions with
Olivia, and avoid Olivia interference with ROS, and mainly use the 1
baud mode for VHF/UHF weak signal work where it is needed the most.
Right now, an automatic Pactor station is also disrupting ROS on 14106.
Just my personal opinion...
