FBS Dynamic Filters
This tab contains the fifteen dynamic filters, with a scroll bar to display filters hidden due to
dialog box size.
Dynamic filters are notch filters that are cut only, providing attenuation up to 30 dB at the
specified Q. The default Q is set in the menu, but can be changed on
Tools>Options
the settings tab prior to engaging the FBS dynamic filters. Changing the Q setting after
dynamic filters have been generated clears all dynamic filters.

is closed, lock mode is automatically disengaged.

button to write the designated filter settings to the first available filter in the
Move to Fixed

NOTE: When a dynamic filter setting is moved to the fixed filter, it automatically
clears that frequency from the dynamic filter.
