Nope. As soon as the HF users reach a certain level of decline,
the FCC will auction-off the HF band for use in WI-FI local
broadband networking, telling the hams to enjoy "2 meters and down."
Count on it.



Parts of the HF spectrum will always be protected for military and emergency
communications.

The remainder isn't very much spectrum for broadband purposes, especially
considering the high noise levels and possibility of interference from just
about anywhere in the world.

Building compact, efficent antennas is a real problem at HF, and using
higher power with inefficent antennas hardly seems like a good solution for
a battery powered portable..

Indeed, Frank. I wonder if many of those people who would propose to
use HF as if was the new frontier of digital communications know exactly
what they are dealing with.

HF is an unruly beast, where sections can be entirely shut down
depending on solar activity, or a small signal can sometimes be
propagated across the world. In addition, it has nowhere near the
bandwidth capacity of the higher frequencies. And finally, the ham
sections are such a small portion of the HF spectrum, that it would not
make much difference if they went away or stayed.

Most modern "wireless" apps *need* the characteristics of GHz +
frequencies.
