Utility Monitoring

The best way to describe Utility (Ute) monitoring is to use negative logic; it excludes CB, Amateur and 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.
