hello harry.... 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. david/wd4kpd
