well regarding the sideband issue, my understanding is that
it was done that way because of the technical limitation of
the mixer or sideband filtering method of the rigs back then would no
allow the lower frequencies to
maintain the mark high for RTTY. i don't think there be any
modern rig today that has this problem. so now it is only because
of tradition that this is still done. it could be changed.
as to the channels, with modern rigs 100hz is routinely done,
and all the stations i worked these past few days on wsjt
have all been well within this tolerance. it seems that at
least trying would be better than taking up unnecessary
space by trying to qso with a very wide df.
just trying to help.

same you should say for USB too.

standards. They make life easier. That is their purpose I believe.
