While it is certainly possible to make QSOs using RTTY on
160 meters, it is far from optimum given the constant
multipath conditions and poor SNR that exists on the band.
It would certainly be possible to make QSOs on 160 using
spark but nobody would do that.
Trying to "force" QSOs - even a contest - using poorly chosen
mode is neither "good amateur practice" or "gentlemanly."
If you want to use digital modes on 160 meters, find a
mode that works well in low SNR, multipath conditions and
in a restricted bandwidth.

What is pioneering or inquisitive in trying to force QSOs
using a mode not suited to the frequencies in use? Everyone
would be better served to use that pioneering inquisitiveness
to develop and promote a mode suited to medium wave conditions.
given that the primary propagation issue on 160 is multipath,
one could even postulate that 22 baud 22 Hz shift FSK would
provide an order of magnitude improvement over 45.45 baud
170Hz shift with about 20% of the bandwidth.
