Pushing the XFIL button will allow one to toggle through the filters. Is the toggle sequence tied to the physical position of the filters mounted on the receiver board?
Yes. For this reason, we suggest putting the widest filter at FL1, etc. However, when rotating the DSP controls, the optimal crystal filter is selected strictly based on the bandwidths you’ve entered for each filter in the menu, so you can place them out of order if desired. You can also specify which filters are available in each mode.
