Hey Sau818. Don't know where you're at with your situation or if you've given up or what. But in looking for things to rectify an issue I['m having and to help my reception be the best it can be, I ran across this little bugger. Maybe it is just what you need? For $12.99, it might not hurt to try it?

And without going back and re-reading everything, it's easier to just do it this way. Anyhow, with that said, I can't remember if you said/were the one who's thread/post I read that stated you also had FM? If so, maybe you need or can then also try this/one of these. Or another type of filter maybe?

Just offering suggestions.
