The nice thing about the KDSP2 is that you can tailor the settings to do different things when required. I have had good luck reducing atmospheric and similar wideband noise, effectively lowering the noise floor (sometimes to the point where, in the lack of a received signal, you can hardly tell if the radio is on. I also have the KNB2, which acts on different noise types than the KDSP2.
