If that's true, I think it already would have happened. The US is one of=

only a
very few countries which has mandated "mode sub-bands".

The US is also one of the few countries with a large and relatively
affluent amateur radio population licensed to use relatively high
powered transmitters.

Canada, IIRC, has less than 1/10th the number of hams as the USA,
spread out across a larger area. Of course Canada also has a
proportionately smaller population. Yet the Canadian HF ham bands are
virtually the same as the US ones. Perhaps Leo can give us a more
precise comparison, and the Canadian amateur power limit.

The problems of repeater coordination on 2 meters (a band wider than
all amateur HF/MF bands put together!) show the difficulties of
depending solely on informal agreements. And repeaters are relatively
local!

It seems to me that it's more spectrum-efficient to have like modes
together, rather than mixed.

There's also the robot station situation to consider.

IMHO, narrow and wide modes do not coexist well. That alone is a good
reason to have subbands-by-mode, or at least subbands-by-bandwidth, on
the ham bands.

btw, Hans, when are you going to submit your restructuring proposal to
FCC?
