So not to be repetitive here or off-topic... Your filter choices are normal which is default and applied to every object per Global filters. Unless you go in to a site or sites of a system or Department options that cover a conventional object and change it from Global to a specific filter, otherwise normal will be applied to every object. That's for a reason. You do not want to monitor Auto filters as Budd indicated, they sample all filters on every frequency and slow scanning way down and you never know what filter did the trick anyway so you really have the choices of... Normal, wide normal, invert or wide invert. Of course you can always choose no filter at all but... No RF interference in your area? You would have to live in the county of Nye. LOL.
There are very good posts in Threads in Uniden Tech forum. I've made several post on the detailed adjustment of filters and the best way to do it. Take a look there, kind of topic here.
