There was "detection".. The automatic areas were set up for "packet" and that's always had carrier sense or even audio presence detection. It was the same automatic vs manual station issue then. The whole idea was if you swim with the sharks (operate within the automatic stations segment) then don't whine when you get a toe bit off. This would still be a good solution. 1/3 the band for narrow museum modes. 1/3 for voice modes and 1/3 for modern progressive modes with no rules or bandwidth limits and let technology rule. 73 Bill - WA7NWP
