Hi all,
those are the right arguments and it's desirable to adhere to this de
facto standard, as Joe wrote.
It's not a de jure or a technical standard as who is operating
"whistling modes" there had chosen to channelize there "almost
improperly". Channelized was then a must, now is too often a problem.
But that isn't my main concern. :-)
I strongly hope that also who operate in any DX expedition could take
care of those facts, one for each band.
Often, if not every time, there is a DX expedition operator that choose
one of those now de facto wrong QRGs, i.e 10.140 - 14.080. Then whoever
him is at that time he get QRM, weak to high QSA and more than one
signal usually, from any sort of whistled digital modes.
One of those two things is wrong:
the de facto use and land owning by the whistlers there;
the appropriate usage of those frequency for DX expeditions when they
are in RTTY.
I am not against whistlers, of any tone, and I am not against DX
expeditions RTTY operators. But the latter must become aware of the de
facto land owning act imposed by the growing of the firsts.
Somebody have to tell this "whistling act" to DX expeditioneers, those
great expenses, those great efforts to pursue contacts also with the us
poor RTTYers and that unknown knowledge of what is getting more and more
low the QSOs rate quite anywhere. (WARC bands are the worst!) It's
unbelievable.
This could be the wrong perspective since I am nailed just here, why not.
:-)

Since RTTY frequencies are generally the frequency of the*MARK*
signal which is the*higher* of the two tones, I would recommend
avoiding frequencies below xx.080.5 to keep the entire RTTY signal
outside of the JT65 and JT9 areas.
It gets very annoying to hear high power RTTY contest signals in the
relatively narrow segments for JT65 (xx.076 USB carrier) and JT9
(xx.078 USB carrier) during even the "fringe" RTTY contests.
