== Limitations ==Not a digital trunked radio system receiver, will not receive the latest police and emergency communications.  he object of trunking is to allow many users to share a relatively few frequencies. A trunking system is controlled by a computer. Information (data) is exchanged between the system radios and the computer on a control channel, sometimes called a data channel.  A group of police or fire department mobile units may be assigned special talk groups, up to 100, each making up to 28 frequencies, 4 of which may be used as control channels.  When the officer presses PTT data is sent to a computer that uses software to manage and select an unused frequency.  The computer, via the transceiver circuit, sends that data to all the radios in the talk group of the officer.  This is, in all practicality, an instantaneous process that happens each time a communication is sent.  To receivers such as the AR8600 the tracking data will simply sound as static or buzzing.  The communication cannot be followed.  Furthermore, the communication bands are typically half that of analog narrow-band.
