If you simply raise AGC Threshold, you will have to lower AF Gain or risk overly loud audio from stronger signals.  So what you would effectively be doing is translating upwards the K3's dynamic range into higher rf levels.  This is NOT good practice - you want to keep the dynamic range operating at lower rf levels (thus all the talk of gain throttling).

This is true, but seems to be a VERY hard point to get across. Running
excess gain in RF/IF strip is at the root of some number of
complaints.
