Ryszard,
Check with W2VJN at INRAD (www.inrad.net). George has filter
switching and cascading boards that will allow you to add
1.8KHz and 250 Hz filters to the FT-920. With the added boards,
you can maintain your existing bandwidth and add the narrower
filters when needed which provides 16 poles of filtering in
the narrow mode.
73,
... Joe, W4TV
