Until recently, I have been scanning the local sheriff with my whistler 1040 scanner. (Jasper county, Mississippi) I'm fairly close to the tower on hwy 531. For two weeks now I've heard nothing. I see on this site that they updated something last week. I know that this scanner will only hear phase one. Now, on this database, it says phase two. Did they change that? Is that why I suddenly can't hear them?
