I purchased an SDS 100 recently. I put in my zip code and downloaded frequencies from my area successfully and listened to what was going on police/fire wise. I then did a firmware and database update. When I now put in my zip code I only receive one system to monitor, not like I received prior to the update. The same service types are turned on prior to and after the update. The Sentinal software update is on the computer as I can make favorites list from it. It just does not scan my area when I put in the zip code. Any thoughts or ideas?
