Hi Paul, How well your idea performs in practice would, I suggest, depend on the strength of the wanted and unwanted signals of course, but also on the *in passband* and skirt region IMD behaviour of the roofer(s), and all 'stages' that follow vs.applied AGC. Any IMD 'weakness' in this area would result in a compromise.
