It all depends on your residential or listening location, as the Uniden SDS line is designed to sort out the competing simulcast issues. If you are between competing towers, or in your case close to competing counties who share towers, you will have simulcast bleed over or missing transmission issues. Do some research on where your P25 towers are, and if that will be an issue for you. For others that may not be an issue if they are sitting next to a tower or within a few miles of one tower and far enough away from the other as to not cause simulcast issues. As always with monitoring, no two situations are alike and YMMV.
