Hmmm I thought that was already part of the
rules. If you dont listen, and transmit and intefere, that IS against the
rules.

The
response from Tom K1KI, ARRL New England Division Director, was
"I'm guessing the FCC wouldn't want to get
into legislating listen-before-transmitting protocols - that's probably
something the ham radio community should be encouraged to work on. I've
already started some discussion within our Technology Task Force group."
Since we've been suffering this problem for years
with no sign of leadership from the ARRL in its resolution, trusting
anything short of (admittedly inflexible) FCC regulations is
difficult..

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.
