Also, digital radio might not have the same fading and static crashes

that
analog radio has, but I can't imagine how digital radio can be free from
dropouts and digital SW certainly can't fix the occasional dead
propagation
problem.


It can't, of course, but digital broadcasts can still sound perfect when

the
signal to noise ratio of the transmission is such that no human could make
anything whatsoever out of a standard AM or FM transmission.


Then, for SW digital broadcast radio to be successful, the listeners will
still have to accept the unreliability of SW.

Reliable communications have never been cheaper, and they will get much
cheaper yet. I think the day will soon come when SW radio won't be the
first choice for any business or government worldwide communication.

The SW spectrum will only be useful for emergency communications and radio
hobbyists. Ideally, SW would be administrated by an agency something like
the National Park Service. Benign neglect would also be OK.



The same could be said for direct broadcast satellites. Such satellites
would provide highly reliable, clear sounding radio (or TV!}.


Good point. I suppose some of the push for DRM is so that the terrestrial
broadcasters can actually compete with satellite radio, just as cable TV

in
the US has been forced to upgrade its services given the competition from
the DBS services.

I'm not convinced the average radio listener cares much about fidelity.
Neither AM nor FM stations normally approach their fidelity limits, but
those stations seem to be attracting listeners just fine. Satellite's
appeal seems to be it's wide range of programming. Digital radio might
support a larger number of channels for the terrestrial broadcasters. I
think Clear Channel might be thinking that all those IBOC channels they plan
to install can be used as a sort of super-SCA scheme, if IBOC radio falls
flat.
