I think you're well aware of the answer. Not every FM station will be
able to use 400 Khz. Some can have only one sideband at maximum power. A
small percentage can't use either sideband. Life is rough when you're
trying to maximize spectral efficiency.

In fact a very small percentage will be able to use 400 KHz at their
assigned frequencies. We had this discussion once before, since the
Ibiquity spec posted he

That's why the industry is pushing for asymmetric sidebands. 200 KHz is
a compromise when 400 KHz isn't feasible.

It's absolutely vital to the future of terrestrial radio to move to
digital broadcasting. It's the only way to remain a relevant choice.
We're not talking about radio enthusiasts, we're talking about the mass
market which matters to broadcasters.
