An impressive looking measured curve, but no guaranteed specs. Having built many filters, I can tell you that repeatability is a huge issue in the case of a 160 BCB filter, now that you have to reject 1700 (I have a local station there :-(. You can always tweak one by hand tuning to look very good. How do I know the one I purchase is going to look so good?
