I do not believe that is true, and the graphs at

bear the real facts as well.
Raising the AGC Threshold allows stronger weak signals (less than -100
dBm for THR=008) NOT to activate the AGC.  

The graphs are dependent on gain level that is set in the rx.  If there's any hope of alleviating pileup mush by raising Threshold level, I believe it would be true (that stronger signals will raise audio level).

When I throttle the gain, I notice that lowering Threshold lowers audio level of stronger signals.
