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

I suppose so, although I think it's safe to do that, in many areas, the
reliability is a very slowly changing function (i.e., dependent much more on
something like the sunspot cycle rather than local atmospheric conditions).

The bottom line is that digital broadcasting can make SW more reliable than
it is now. True, it will never approach the 'realiability' of a local
broadcaster, but presumably the typical use of SW (excluding hobbyists for a
moment) is when the local broadcasts are either unavailable or considered to
be too heavily influenced by the local government.

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.

Yes.

The SW spectrum will only be useful for emergency communications and radio
hobbyists.

I'd wager that the users of the HF spectrum for free e-mail services such as
Winlink 2000 won't go away any time soon either. :-)

I'm not convinced the average radio listener cares much about fidelity.

I think they care a lot about fidelity, but not how you'd typically measure
it. To the average person, static or fading is far more annoying than heavy
compression artifacts (that abount on XM and Sirius) or even short dropouts.

Satellite's
appeal seems to be it's wide range of programming.

True.
