Novice question on the Crystal Filter boards

James Lawrie


I have a question(s) about the Crystal Filter boards that I need some professional advice/information from the group.

1.  Is it possible to use standard crystals and achieve a 50khz/25khz/10khz bandwidth for AM/FM reception?
2.  Any links to a windows based filter design software available?

I lost my old software when my disk crashed and my old saved links are hitting dead ends, I not keen on the online calculators that I’ve seen out there now.
