Adding to that...AGC SLP has a profound effect on the AGC compression ratio. 
Higher settings make all signals sound relatively the same.  A few posts 
back, I recall seeing comments about how signals on a Yaesu transceiver 
seemed to "pop out."  For that to noticeably happen on the K3, AGC SLP will 
need to be set for lower menu values.  From the K3 manual:

AGC SLP - (Advanced.) Higher values result in 'flatter' AGC (making signals 
at all amplitudes closer in AF output level)."  My AGC SLP setting is on the 
lower end of the range as I actually prefer audio dynamic range rather than 
homogenizing everything on the band.

Aggressive AGC SLP and AGC THR add to a perceived increase in background 
noise and signals that do not "pop out."
