I’ve noticed that the WBX can be used with a grand-daughter board. The
schematics of this board are found at

What are the specs for the bandpass filter labeled FIL1? I don’t see a
part number given.
Also, is anyone aware of a grand-daughter board that has switchable
bandpass filters that can act as programmable RF freq pre-selectors?
