Absolute nonsense. Anyone who has spent much time actually operating 160 meter
RTTY knows it works just fine. This is one canard that should die a quick and
merciful death.
On all the HF bands, 10 kHz is enough for nearly all non-contest operating,
including DX chasing. When there is a contest more space is taken up, but on 160
meters this would not likely be the case because of much shorter propagation and
fewer participants anyway. 160 is never open world wide like many HF bands are
and comparing the bands in that respect is ridiculous.
