take the RF frequency minus 1000 Hz and set that as your dial reading.
This avoids the confusion when two stations are using different tone
frequencies (or sidebands) and therefore have different dial readings.
Everybody calculates their own personal dial setting depending upon
how they are operating their equipment.

providing a community high-speed Internet access by amateur
radio could be considered public service and justification for
spectrum.

despite the corporate PR, in many communities there is no Internet
access other than via modem.  This is particularly true in rural and
2nd/third tier cities.

developing, applying, and running higher-speed wireless Internet
services in the community would be welcome by significant portion of
the population. It could advance technical knowledge in the hobby.  It
would be good PR.  It would attract technical people into the
hobby. It would go a long way to changing the image of amateur radio
from a bunch of overweight, aging, white men with ugly towers in the
backyard playing with low-tech radios to something a little more
modern.

unfortunately, we can't do this now because we are limited by the
content prohibitions in our regulations.  those restrictions are
important because they do provide barriers against commercial use of
amateur frequencies.  However, I do believe it is possible to rework
those regulations such that we would be allowed to carry Internet
traffic but not as a commercial entity.

I'm a little confused how this might work. I assume by "high-speed"
you mean faster than modem access, i.e. cable or xDSL speeds?

How would the ham radio system access the internet, other than
via modem?

So you suggest higher speeds than are available via modem?
How would the hams get this higher speed access to the internet,
so they could share it in the community?

Try a simple example. 100 users in the community, online via
high speed ham radio links. Let's assume 256kbps for the ham radio
links, so they are at least a little faster than the modem dialups.
That's 25.6 Mbps total bandwidth required of the ham radio links.
However the ham radio system connects into the internet must
supply this bandwidth. How could that be done? Who would pay?
