Not "whining." It's a technical barrier to reach "high speed"
approaching T1 rates on small slices of bandwidth. ALL radio
services face that same problem.

If at least 1 MHz of the 10m band could be used - at the
expense of ALL users of that portion of EM spectra, there
would be a chance for at least NVIS propagation at high
rates. That is NOT likely to happen for a minority of High
Speed fans to go against the overwhelming majority.

Mere resistance to the establishment is NOT a "just cause."
One MUST justify that resistance in order to begin changing
things. That justification is what the Students Wildly
Indignant about Nearly Everything (SWINE) usually overlook.

For "high speed" (really medium-low speed), the commercial
side of communications has developed the 56 KBPS modem
that works on a 3 KHz bandwidth. That is starting to bump
up against Shannon's Law, an extremely real technical
barrier. [it doesn't exceed it but it is close enough to almost
reach out and touch it...]

All electronics and radio works by the same Laws of Physics.
Those Laws are immune to the feelings, emotions, and
general imprecations of mankind. One MUST learn those
Laws and work WITH them in order to get them to work FOR
you.
