K3 filter gain

N8CEP
A filter question for the group if I may. I have the following filters in my K3:
2.8/8 pole - 1.8/8 pole - .400/8 pole. My question is how much gain did you
add in the K3 utility for your filters and how did you determine the necessary gain?

Thanks for all who responded! I got my answer from an older post by N6KR.

My K3 S/N 00018 filter settings are those shown in the K3 Utility Help
screen shots for the Crystal Filter configuration.

There's a table in the K3 Utility page help text that describes the
recommended ranges of gain settings. This table is derived from the owner's
manual recommendation. At one time I had higher settings in an attempt to
keep a centered signal at the same volume as the bandwidth decreased, but
Wayne helped me to understand that this wasn't a good idea.

The owners' manual recommends 1-2 dB for 400-500 Hz filters, 3-4 dB for
200-250 Hz filters, and 0 dB for filters wider than 500 Hz.
