Only problems with a BP filter (aside from its gradual skirts,
unless it has 5 poles or more) is you will have to disconnect
it to listen to other freqs and its attenuation on the likely
culprit, FM broadcast, will be minimal.

The scanners are dedicated to airband (providing feeds to LiveATC.net)
so removing the filter isn't an issue. I installed an AOR ABF-125
filter tonight, and the overload problem seems to have been solved. I'm
still not overwhelmed with the quality compared to what I get from my
airband transceiver, but that's $300 vs. $100, I guess. I might try the
FM notch filter, too, and see if that makes things any better, but for
now, at least I'm up an running. Thanks to everyone for their help /
suggestions...

Also try one of the real cheap FM notch filters from Radio Shack. For me,
it worked better than the expensive PAR one with an FM broadcaster a mile
away.

I installed the PAR FM notch filter tonight, and it made a huge
difference over the bandpass filters I'd previously tried. I'm very
happy with the quality now, and I can avoid having to upgrade the
scanners to real aviation recievers. Thanks again for all the input...
