Folks, the KFL3-FM filter seems to be hard to get, but Chinese copies of the CW filters are available at fair prices. There is a page with the schematics of all the "narrow" Elecraft filters KFLxx-A but not for the -B FM filter. I have an schematic for an LC filter in order to listen with wide bandwidths but would like to know which changes are required on one of those -A filters, if possible at all, to get an FM filter. Most of other references I have on ladder filters are for SSB or CW/Data narrow filters.
