No matter
how advanced the mode; If you have no-one to connect with, you're not going
to move much data.

Once we get the FCC to write restrictive rules, it's very hard to remove them.
The only unattended mode allowed is packet using 2FSK, and if you can't run
unattended, why bother. Thus the stagnation and apathy in digital radio relay.
Meanwhile psk31 and others are very popular as the attended mode.

Until we get rules that allow experimentation, ham radio will always be about the
white man with the most money and power, rather than any other feature/future.
