Joe, Its a new pager that switches frequency, just recently put up. Fortunately, we're all on good terms and yes, we're a freebie ham group. So that's why we thought about a window filter for them to get it down 30 or 40 db and we'll do the rest on our end.
The original question remains... does the pass go in front of the notch or the notch in front of the pass or does it make a difference.
