These are the two that I have changed from the default.

I decreased the value of SLP so that there would be a greater perceived 
difference between weak and strong signals.  I might increase it in a 
contest to protect my ears and reduce knob twisting.

I reduced THR because I do not want *any* AGC action on the weakest signals.

Your preferences may definitely vary and Lyle's advice to try these 
parameters to see what happens is good. You can always find out what the 
default was by pressing DISP, so you don't need to worry about getting lost.
