That's exactly how I set mine up. Lower the AGC-T to where the band noise and 
weak/moderately weak signals aren't hitting the threshold. So maybe S4-5+ 
signals do hit the threshold. I'm able to still hear the "at noise floor" 
signals without pain in the ears from strong signals. They're loud, but 
manageable. 

tnx
