Quite hard to do as nobody's situation will be the same. It might be a pain but it is what it is. If you don't want to mess with them then you are missing out. Taking the approach of not messing with them might just as well sell the unit and move on.I'm not a HAM and I have no idea what any of the filters do. (I'm also not messing with them) It would have been nice if Uniden had added a page or two listing the filters and describing the purpose and function of the various filters.
The SDS scanners are not "plug and play" devices. You set them up and begin down a the road of experimentation. If you are in a large metro area with high RF levels like I am, that road is a long road. At the end of that road, in an environment like mine, perfection is unlikely, but you should achieve acceptable results overall. The smaller your community, and the lower the ambient RF level, the shorter that road will be. There are no "rules of thumb" for the filter settings....usage will vary based on circumstances and your goals. Only you will find the correct answers, and only by experimenting.Quite hard to do as nobody's situation will be the same. It might be a pain but it is what it is.

You may not need the filters at all then. The SDS filters primarily help compensate for a receiver that is prone to being de-sensitized by strong radio signals. These signals can be on nearby frequencies or even “out of band” frequencies. If you don’t live anywhere near radio towers, including near cell towers, then you may find “Off” to be a good choice for your Global filter setting.<snip>
