Unidentified Digital Radio Systems in our area

  • Please also post in the Mystery Frequency Forum as well
  • This list is a working list of unidentified digital scanner frequencies, that we need help in narrowing down who, what and where.
  • Once Identified the record will be moved to the appropriate section of the main wiki
  • All digital formats are welcome here. (DMR, NXDN, TETRA, etc...)
  • This table covers all of New England and the 25 adjacent counties in New York State.
  • Nothing here is assumed confirmed until it is.
  • No covert, undercover, or surveillance type traffic allowed, both public and private. (Please read our Terms of service)
  • When removing an entry, please ID who the user was in the edit summary, so we all can go back on the answer!
