obviously test the filter to see how well it works before working hard to integrate it.? and take advantage of natural integration of the AGC board.? I am confident you would find a way somehow.? also okay to experiment to 'prove' I am wrong with my recommendation.?

Its the intermodulation of huge signals that reach the MOSFETs up front in the AGC that would concern me.? When they get a strong bias to be completely on or off they may have okay performance, but a bias voltage in between often makes it more susceptible.? yes the mosfets behave like a resistor, but there is also a transistor junction there that can operate like a mixer - not the behavior we want.? I imagine in the vast majority of cases the ubitx operator may not need a BCI filter - but in Joel's case he clearly thinks he needs it.?
Experiment on.? Results are generally 'numeric' and actual operation will tell the truth.?
