KH,
ROS 1 baud, is just the less interference produces to others modes. Before quit
1 baud, i would quit 16 bauds.
So, has no sense what you proposse.

Asunto: Re: [digitalradio] Spectrum is for ALL users
I agree that is easier. The problem is that 14109 has been designated as 1 baud
exclusive, so that is not suggested as available to go to. Even though is an
advantage to being about to work at -35 dB S/N, the advantage is much greater
at VHF and UHF, where atmospheric noise is a greater problem than on HF. So, if
14109 is not suggested as exclusive to 1 baud, there will be more space for HF
users of ROS to go to avoid QRM or ROS interference - practically, on 20m,
twice as much space.
