The narrowest filter settings (50 Hz and 100 Hz) are actually steeper than this, and the IIR filters (menu selection) are different, too.

Of course, I admit to bias... 73, Lyle KK7P On Mon, Nov 16, 2015 at 8:38 PM, Dave Hachadorian <k6ll.d...@gmail.com> wrote: > Is the reference to the DSP filter system or the roofing filter >> system? >> > > It is all about the DSP system.
