I think this is a lot easier. If you see a channel is occupied by Olivia, go to
another channel. And if you see that a channel is occuped by ROS and want to
transmit with OLIVIA, do the same.
What i cannot say is "The 20-meters band is only mine".

Asunto: Re: [digitalradio] Spectrum is for ALL users
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...
