This has the same problem as the ICE filter.  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?
