I have no argument with your concern of QRM, but whether the unknown
station actually heard something is speculation and not a scientific
evaluation. If the person heard him he is wrong. If he truly heard
nothing then he is legally permitted to be there and the other digital
users must realize that also. Closing the spectrum to special groups is
not the answer. I gave several other arguments that are the same case
in point and their perceived ownership of the spectrum.
It is kind of funny after every RTTY contest there is some sort of
dilemma usually it is the improper programming of macros. At least we
have a new topic.
BTW I do not care what your macros look like, just call me I need all
the points I can get.

Neither JT65, JT9, PSK31, PSK63, nor PSK125 sound like "random noise".
All have a distinctive "sound" and are clearly identifiable on a
waterfall or spectrum display. It should even be possible to make an
informed guess as to the mode just based on the frequency - the
"center of activity" for each digital mode is published just about
everywhere except in the contest rules.

"QRL? in their mode"
In other words, given that all digital modes are permitted within the
spectrum allocated to digital modes, and someone may be listening to a
transmission I can't hear, and if I can't hear it I don't know their
mode,
you basically suggested that in order for me to begin transmitting a
digital signal, by good operating practice I should toss out a QRL?
in all
possible modes first - presumably including modes that require
proprietary
modems costing thousands of dollars. That's kind of a hoot.
To bring it back, if we all took the position and "if it sounds like
more
than random noise it is a signal" then if I send out a RTTY QRL? and you
make a noise in JT-something (guessing I sent a QRL? because what else
would I do?), I should be able to take that as a "yes" and move on. Good
manners.
