| − | == Utility Monitoring ==
| |
| − | The best way to describe Utility (Ute) monitoring is to use negative logic; it excludes everything defined above. Not CB, Amateur nor Short Wave Broadcast. This includes, but is not limited to, aeronautical stations, digital signals (outside of the specified amateur bands), military, maritime, federal and other users. See our [[Utility Monitoring]] page for more information and links.
