200 kHz is too narrow?

I operate regularly in the ARRL-recommended 1800-1810 segment. I have heard a
non-digital signal there only once in a non-contest period. If there was a
dedicated 160 meter RTTY contest, I doubt if the 'regulars' would even notice.

Granted, you probably won't be working the other side of the earth on 160 RTTY,
but hams love a challenge, don't they? I have 25 states worked on 160 RTTY and
would love to get 'em all. To the best of my knowledge, no one has WAS on 160
RTTY yet. Who will be first?

Antennas are easily re-tuned for 160 meters, either with a loading coil or by
clipping on a couple feet of wire. And SWR losses are lowest on 160 of all bands
anyway.
