As far as I'm concerned, the main objective would be to limit AGC action.
Depending on the radio, this might mean turning down RF Gain/turning up AF
Gain, increasing AGC Threshold, or turning off AGC. But for this to work,
you need a wide audio dynamic range so that you have a high ceiling above
the faintest signals you can discern - otherwise the static crashes will
blow your eardrums out with the high AGC threshold. K3NA has written
extensively on the subject - Google will list his articles.
If you don't have a wide audio dynamic range, you'll have to resort to
other methods but you'll always be hamstrung in battling with the AGC.
