[Elecraft] K3 - Audio/IF filtering definitions

[Rick Bates]

The filter sets the rough bandwidth limits.  Then you can shape the
resulting audio with the equalizer to your particular need.

You can also narrow the gross bandwidth with the width control and/or
re-center the bandpass with the shift control and/or narrow one edge of the
bandpass (at a time) with the high/low cut.  

Think of the high/low cut as a gross equalizer, similar to the treble/bass
controls on an old stereo.  They CUT above (for high cut) and below (for low
cut) at the threshold that you set.

This leaves you with several methods at your disposal to shape, enhance or
eliminate portions of the audio band so you have the best chance of getting
what you need from the signal.

And then on top of that, you also have a very effective notch filter.
