I just checked the database for Marshall county and I don't see any recent changes. Could the channel accidentally been locked out of the scan menu. The DB shows Marshall county is still using Digital VHF, if you have the wrong NAC code you might miss the traffic. I pasted this data from the DB might make sure these are programmed into the Uniden Home patrol scanner.
