I was happily scanning away on my SDS200 Memphis area already loaded with local departments until I got the bright idea to use Parallels, Windows, and Sentinel. I won't bore you with the details but the bottom line is that my brand new SDS200 is now a brick. Is there anyone in the Memphis area who can help me resolve this. I have used RR Forum and also Uniden Group on FaceBook, and have called the vendor, Scanner Master which I thought would be the ideal source but all failed. I think this is going to need hands on help. If you are in the Memphis area, or know someone here, or have another idea, please let me know.
