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 com-
munication 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
control
frequencies for Motorola systems or all the
trunking
group
frequencies for EDACS in one bank (see
“Storing Known Frequencies into Channels” on Page 25)
and input ID codes in the ID memory (see “Storing Talk
Group IDs” on Page 58).
Your PRO-93 automatically calculates Motorola voice
channel frequencies when it decodes the control chan-
nel. This eliminates the need to enter all the Motorola
group frequencies.
The control channels are subject to change depending
on the day. Therefore enter all the control frequencies in
the same bank. If you do not know which is the control
channel, it is better to enter all the system frequencies
into the same bank. (Refer to the supplied
Trunking
Guide
.)
When the scanner decodes the Motorola control channel
and finds the voice channel, the scanner displays the
control channel memory location on the top line, the re-
ceived frequency with VC (voice channel) on the second
line, the bank and control channel memory location num-
ber on the third line and the Motorola ID number on the
bottom line.
