I live in central Utah ( non-encrypted scanner paradise ) and I just got a new Uniden SDS200 scanner about a month ago. One problem I have with listening to local stuff is the 'listener fatigue" I get from weaker signals that pop in and out of background static all the time. The incessant KKKK-kkkk-KKKK static noise can be annoying to listen to when you get a police unit that comes in weaker than the dispatch ( just an example ). All of that makes it a bit stressful and difficult to listen for long. I realize that if Uniden built in a DSP chip to help process that out it would make their scanners more expensive and possibly even bigger. My thinking is I could try a dedicated DSP speaker to feed my audio into from the back of the radio and maybe that would take some of that scratchy static out?? Ham radio operators use them for both CW and regular talk on HF. But I don't know if that would help a scanner like a Uniden that has less than stellar signal to noise ratios at VHF and UHF frequencies. Is digital signal processing of my audio output the answer to my ills? All I know is all the crackling is louder than heck compared to a good quiet signal at normal volume levels. Very irritating.
