I have been on 6 meter RTTY since 1964. See QST,
February 1965, p.77, for Sam Harris's report on early
6 meter RTTY meteor scatter work.
Ham tradition is for RTTY at 80 kHz above the
low end. This is not legal on 6M, so 50.180
seems reasonable. PSK operation near 50.260
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 is a good
place for plain RTTY; it uses 170 Hz
shift and causes much less band usage than
3000 Hz wide SSB. RTTY at this location will
cause no serious interference to SSB operations.
In case of sizable activity, the segment
RTTY 50.180 to 50.190
is the reasonable choice.
