Putting RTTY activity of any kind - much less contest activity -
in that heavily used CW spectrum in North America will start a
range war and certainly renew calls for the ARRL to ask the FCC
for mode limits on 160 Meters.
Due to the severe multi-path effects on 160 meters (refer to
Chen's information), RTTY is inefficient at best. Add the
QRM from a contest and QRN and any RTTY contest will do nothing
more than make RTTY operators and contesters less popular with
the average amateur than they already are.
If you MUST have a digital mode contest on 160 meters at least
use a mode that is designed to combat the multi-path conditions
that are the rule at medium frequencies and conduct it away from
the areas of heavy CW/SSB activity.
The military has long understood the problems with multi-path
and RTTY at MF and LF. They use wide shifts and very slow data
rates to circumvent the problems.
