Concur; the plug-in filters at the bottom right of the signal
conditioner photo I sent earlier are homebrew BPFs based on W3NQN design
criteria. Ed published a two (2) part article in May / June 1998 QST
that discusses the design background (available in ARRL QST archives).
The ones I built are on smaller cores than those cited in the article
and likely those Jay sells, so windings were modified accordingly using
W3NQN's design guidelines (and some correspondence). Nonetheless, they
work excellent.

The W3NQN-designed filters that Jay sells are excellent.
