Fred,
My understanding --
The roofing filters are at baseband (audible frequencies), but are
inserted prior to the conversion to digital - that means the DSP will
not see content outside the roofing filter range and the possibility of
overload in the A to D conversion is greatly reduced.

I got a kit, partly because I did not get the roofing filters.
Without those, a kit KX3 is fully aligned at the factory.
How do roofing filters work on a direct conversion radio? That's not
a snarky question, I don't know and would like to.
