The waterfall/broad as a barn door issue is *not* applicable when the
RTTY contesters come down below x.080 and land directly on top of the
JT65/JT9 signals - or go all the way down to xx.071 and wipe out two
or three PSK31 signals at the same time.

It's not the low power signals ... I've seen it on S9 signals ... the
RTTY ops think they have an inalienable right to QRM any other digital
mode in spite of having nearly > 70 KHz above 14.080 and/or 21.080 with
which to play.
There is no lack of knowledge that there are other digital modes
between xx.070 and xx.080 *on a regular basis*. Unfortunately, since
the common software (MMTTY, 2-Tone, fldigi, MixW, MMVARI, etc.) does
not decode JT65/JT9, the RTTY contesters don't care and choose *not*
to listen.
It is a simple choice - either listen for a two minute TX/RX cycle to
confirm that the frequency is not in use or don't transmit there. The
JT65/JT9 operators are not coming above xx.080 to QRM the RTTY guys
but I've heard even the weekend/holiday DXpeditioners set up shop just
below xx.080 (18.103, 24.920, etc.) without regard for *existing*
JT65/JT9 activity and listen up 2-5.

So? No contest allows operation there - perhaps RTTY contest sponsors
should take a hint and put xx.080 and below "out of bounds" just as
they have put the WARC bands and the NCDXF beacon frequencies out of
bounds. After all, RTTY contesters don't transmit on 14.100/21.100
even if they can't hear a signal there. Take a hint.

Really? Where does it say that in Part 97?
The non-RTTY digital boys have two self-created problems which only
they can fix:
1. They love their waterfall displays with ridiculously wide
bandwidths. When your receiver is broad as a barn door, what to you
think is going to happen?
and
2. Partly because of #1, they insist on running power which is hardly
more than a night light.
So when their night light gets stepped on by a perfectly legal RTTY
contester WHO CAN NOT HEAR THEM, they cry foul. Well, duh!
Contesters have been very good about not using the WARC bands, ever.
Take a hint.
