It appears that most of your county is on conventional frequencies (not trunked) that you should be able to receive on your WS1040. However, I do see that one of the Dispatch channel listings for the Sheriff's Department is using DMR. That's not a type of transmission that your WS1040 can receive, but everything else should work.
