I have tried adjusting the AGC (labeled "noise gate" on my set) with no success.
Unfortunately the setup I have doesn't allow me to use a different modulator. I have comcast's basic package with the little (POS) "digital adapters" that only have an RF out and outside of plugging it into a demodulator to composite and then back into a modulator there's not much I can do on that end. I do, however, have tons of alignment equipment and even a spectrum analyzer if it comes to it so I'm happy to attempt to modify the TV's IF if a quasi-universal fix could be developed.... I'll certainly post my findings here if I do, but I still need more info on SAW filters before I can proceed
