RadeoEngineer said:FMeXtra gives you the choice of digitizing your analog audio in one of the subcarrier channels, plus an additional full bandwidth channel of programming you choose, or you can split the entire subcarrier region into as many as nine narrower channels.
So what? Look at it from the audience point of view: They have to buy new radios. The same issue as with IBOC. As long as consumers are required to buy new radios, this will continue to be a non-starter for the majority of people in this country, regardless of the system, regardless of the content, and regardless of it being digital.

The FCC has absolutely no interest in granting any more bandwidth to existing broadcasters. None. At least not for free.
