Trunking Operation
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, which
are extensively used in many communication systems.
Trunking systems allocate a few frequencies to many dif-
ferent users. When the mobile unit transmits a signal,
one frequency is chosen from among the allocated fre-
quencies in that trunking system. The user’s ID talk
group is sent with the signal.
To receive trunking signals, you must store all the trunk-
ing group frequencies in one bank (see “Storing Known
Frequencies into Channels” on Page 30) and input ID
