Trunk Tracking
YourBC 235XLTis designed to track Motorola Type I,
Type II, Type IIi, Hybrid,
SMARTNET™, andPRIVACY PLUS™
analog trunking systems
*, which are extensively used in
800 MHz communication systems. When tracking these
types of systems, you may want to remember these
important points:
Your scanner defaults to monitor Type II systems;
however, you can change this if the system in your
area is different. (The types of systems are
discussed below.)
Your scanner cannot track an 800 MHz trunked...

In a Type II system, when someone uses their radio, only
the radio ID is transmitted when PTT is pressed, whereas
in a Type I system the radio ID and its current affiliation are
both transmitted when PTT is pressed.
Why the difference? Type II systems are slightly more
advanced because the central computer maintains a
database which is used to determine each radio’s
affiliation(s). Changes to a Type II system are easier than
Type I because the system manager only need update the
database instead of...

Setting the Squelch
Since Squelch is automatically adjusted in trunking mode,
it isn’t necessary to manually adjust the squelch control
while trunk tracking. However, the squelch setting you
select before you begin trunk tracking can affect how fast
your scanner acquires the data channel, and, in some
instances, the squelch setting can prevent your scanner
from acquiring the data channel at all.
Set
SQUELCHin this
position before
selecting a trunking
bank.
Note:You can
change this
recommended
setting, if...

The first step in tracking a trunked system is storing the
frequencies in one of the 10 available banks in your
scanner.

3. Use the keypad to
enter a frequency for
the trunked system.
For example, enter
856.2625, or enter a

the frequencies
quickly displaying as
your scanner looks
