Mike,
Looking at the response of the 402/402x filter, I really wonder if it
works as good as it looks. The response appears to be flat down to about
1.7MHz, then it turns the corner and falls off a cliff. I suspect the
corner is in actuality much more rounded, and you will lose several dB
towards the bottom end of top band.
Maybe it's worth homebrewing a filter to notch out the offending BC
station(s).
