group, while others have access to many talk groups. The
talk group (s) each radio can access is called the radio’s
affiliation (s).
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...

EDACS®Tracking
TrunkTracker II now allows tracking of EDACS trunked
systems. Until now these widely used systems have been
almost impossible to monitor with a conventional scanner.
With your TrunkTracker II listening to EDACS is
remarkably easy, and perhaps even easier than
conventional scanning.
EDACS
®systems use “Transmission Trunking”, which
means that each transmission is assigned a new
frequency. As the conversation moves through the
system’s frequencies, your TrunkTracker II automatically
follows...

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.

trunking bank.

The first step in tracking a trunked system is storing the
frequencies in one of the 10 available banks in
your scanner.
1. Press for 1.5
second.
You will hear two
beeps, andBANKand

flash in the display.
2. Select the Bank you
want to store the
frequency, by
pressing 1 through 0.
3. Choose the system
you want to track.

4. Use the keypad to
enter a frequency for
the trunked system.
For example, enter

enter a frequency of
the system you’re
going to track.
Note:To clear a mistake while entering a
frequency, press twice, and start over.
Then press .
If the frequency is out
of the range of the
system chosen in this
step, an error

Searching a Trunked Bank
If programming a Type I system, you cannot Scan the
trunking bank you just programmed unless you enter talk
groups into memory. See ahead for details. With the
search function, you’ll be able to find all the active talk
groups within the trunked system.
Once the data
channel is acquired,
the scanner begins
trunk tracking. Talk
group ID’s, which
represent different
service groups, begin
to display.
While searching, you won’t know exactly who the ID’s are
assigned to unless you...

a talk group ID is active
and the display will flash
the frequency on which that
talk group is transmitting.
nPress and hold for
two seconds and the display
will automatically flash the ID
and the frequency alternately
until you set the condition by
pressing the key again.
Direct Entry ID Hold Mode
During Search mode, you can hold on an ID without
entering it into memory.
1. When a talk group is
active, press
to stop the
search mode.
2. Use the keypad to
enter the ID...

ID Lockout
Like conventional scanning, it’s possible to lockout
unwanted traffic. This is particularly important in trunked
systems because in many areas, water meters, door
alarms, traffic signals, and other mechanical devices are
assigned IDs just like other users. Also some departments
scramble or encrypt their communications, and you may
want to lock out these unintelligible broadcasts.
To lockout an ID,
press when the
ID displays.
The ID is locked out,
and the next active ID
displays. You can...

Restore all IDs
To unlock all locked out IDs at once, follow these steps:
1. Press and hold
until you hear two
short beeps.
2. Press to unlock all
the IDs at once.
Note:If you unlock all the IDs, then the Scan List
Memory mode displays. Press to scan the IDs
stored in your Scan Lists or press to return to
the Search mode. For information about Scan Lists
see page 48.
3. Press to return to
the Search mode.
