Several years ago I built he ZLl2CTM design and created a set of filters using the Iowa Hills Sioftware suite. The Opposite Sideband rejection was not so good, I found the original set of coefficienst from ZL2CTM and using those the Opposite Sideband has improved. No eliminated but much better. More testing to follow.
