[Elecraft] K3 XFIL Button

[Ed G]

Seems like the K3 XFIL button essentially does the same thing as the DSP width knob. That is, depending on how the user has set up the filter configuration, both DSP and filter selected are pretty much automatic and linked together. Adjusting the width knob will result in a particular crystal filter being selected, and similarly, using the XFIL button to select a filter will automatically adjust the DSP setting.

On occasion, I would like to be able to use a wider DSP setting with a narrower crystal filter, or a narrower DSP setting with a wider crystal filter.  Some 160 meter CW operation with diversity receive would be an example.   It would be nice to have a quick way to do this without having to make filter configuration changes.  So since the XFIL button and the width knob are somewhat redundant, could the XFIL button be divorced from automatically changing the DSP setting, so one could easily and quickly select a crystal filter other than what is set up in the configuration?  I don’t know if it’s possible to offer that with a firmware change. If so, a Normal vs. Independent XFIL button firmware option would give users the choice of how the XFIL button worked.
