I bought a 500Hz Collins Mechanical Filter on an INRAD board for the 455KHz IF of my FT-817 from W6OA. It definitely works for PSK31 and I'm using it now to monitor N5DEN talking to KC0CWI on 3580, and AB7BS in Florida talking to K4XY in Virginia on 7070. When I bring the filter in the received audio frequency goes up by 250Hz. Hmmm.
