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) 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.
To receive trunking signals, you
must store all the trunking control
frequencies for Motorola systems
or all the trunking group
frequencies for EDACS in one
bank (see “Storing Known
Frequencies into Channels” on
Page 26) and input ID codes in the
ID memory (see “Storing Talk
Group IDs” on Page 62).
Your PRO-95 automatically
calculates Motorola voice channel
frequencies when it decodes the
control channel. This eliminates
