Trunking
how trunking works
The scanner tracks transmissions that use the Motorola Type I and Type II (such as Smartnet and
Privacy Plus) and hybrid analog trunking systems, plus GE/ Ericsson (EDACS) and EF Johnson
(LTR) type systems extensively used in many communication systems.
Trunking systems allocate a few frequencies to many different users. When the mobile unit
transmits a signal, one frequency is chosen from among the allocated frequencies in that trunking
system. The user's ID talk group is sent with the signal.
