Your point was "QRM is inevitable -- live with it".
My point is "QRM from unattended stations is preventable; stop making
excuses and fix it".

As Walt states, there is a need of a pool of reserved frequencies for
automatic or semiautomatic operation, in order to
avoid clashing with others.
I have been a packet sysop since 1992, and it was the way it operated.
Noone who is not a member of the forwarding net is welcome, even in
packet,
I am gearing up for sending images via MFSK upon 12/15/06. What pixel
sizes are recommended for MFSK images? Been so many years since I did
it I no longer remember.

The scenario where neither A or B can hear C or D, but that C or D
are QRM'd by transmissions from A or B is indeed possible, but is
relatively infrequent. No one expects A or B -- whether they are
attended or unattended --

Walt,
If neither A nor B can hear either C or D, then generally speaking that
also means that C and D cannot hear A or B and there would be no
interference problem. There may be rare cases of one way skip, but
nothing can do anything about that.

You are correct, Andyit happens every "scheduled" night. Have
never-ever seen W1AW move or not transmit despite the frequency being
in use...Does it violate FCC statues; sure; is anyone going to do
anything about it? No, as ARRL/W1AW seems to be aloof and un-caring
unless it involves vested
Unfortunately, semi-automatic operation is problematic. The
initiating operator can know that the frequency is clear at his or
her end of the QSO, but can't know whether the frequency is clear at
the automatic station.
For example, I might connect with an automatic station in Nashville

You could host the last automatic digital QSO on 80m. If you ensure
that the frequency is clear at both ends beforehand, then the QSO will
be unique on two counts.
