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.

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? ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
