Your proposals make perfect sense to me Dave, did
ARRL respond ?

Busy detection is definitely feasible. Besides the SCAMP
example,
the SCS modem evidently supports busy detection, but I am aware
of
no software that exploits it. Some Winlink folks were saying last
spring that they planned to use this; if they've done so, I missed
the
announcement.
In reaction to the ARRL proposal to eliminate the
regulations that
confine semi-automatic operation to limited sub-bands, I
suggested
to my ARRL director that two forms of semi-automatic station
automation software be defined: qualified, and unqualified.
Qualified
station automation software is capable of detecting
ongoing QSOs in all
popular modes, and refuses to transmit on a busy
frequency -- just like a
good human operator. Unqualified station
automation software is incapable
of this, and is therefore a QRM
risk to ongoing
QSOs.
Semi-automatic operation with qualified station automation
software
should be permitted anywhere, subject only to the bandwidth
constraints on which the ARRL proposal is based. Semi-automatic
operation with unqualified station automation software should remain
restricted to sub-bands, which in my view should shrink every few
years. This would argue for enforcement via a band plan rather than
via FCC regulations, though the ARRL has not yet shown the ability
to
syndicate an HF band plan, as the current digital mode situation
demonstrates.
The above proposal would clearly encourage the
development of busy
detectors, to the benefit of all parties. Personally,
I would have
no problem extending it to include automatic as well as
semi-
automatic operation.
