Although ham tradition is for RTTY at 80 kHz above the low
end, this is not legal on 6M, so 50.180 seems a reasonable
alternative.  Other digital work near 50.300 is often low-power,
with wide-bandwidth reception of many low-power low-
bandwidth signals in a 3 kHz wide receiver - it is not
compatible with high-power narrow RTTY. I would not want to
interfere with these new digital modes. Thus 50.180 seems to
be a good place for plain RTTY.

With a 170 Hz shift, RTTY causes less band usage than 3000 Hz
wide SSB, so there should be no complaints by SSB operators.
Six meters is a wide band; when the lower frequencies in the
band are full, SSB operators can easily slide over 50.180 and
find plenty of clear space above 50.200.

I have worked quite a few stations on 50.180 RTTY who said
that they just happened to hear me while tuning, and switched
to RTTY to work me, but they would never have tuned up to
50.300.
