Trunked Systems
Your BC780XLT is designed to track three major types of trunked radio systems. These
systems are described here.
vMOTOROLA - Including Type I, Type II, Hybrid, SMARTNET, and Privacy Plus.
Motorola systems are widely used by public safety and business users. Most are on
the 800 MHz band, and recent systems are appearing on other bands.
vEDACS - Including "Wideband" 9600 baud, and "Narrowband" 4800 baud systems.
"Wideband" systems are mostly on the 800 MHz band, and are used by public safety,
utilities, and business users. Some systems are used on the VHF and UHF bands.
"Narrowband" systems are used in the 935-940 MHz band, many by utilities.
(See page 49)
vLTR - These systems are mostly for business users, and found on the UHF,
800 and 900 MHz bands. (See page 52)
For details on the operation and programming for all of these systems, see pages 36-58.
When tracking these types of systems, remember these important points:
• Your scanner defaults to monitor Motorola Type II systems; however, you can change this
if the system in your area is different. (The types of systems are discussed below.)
• The frequencies for many of the trunked public safety systems are listed in the
TrunkTracker National Public Safety Trunked System Frequency Guide included with your
BC780XLT scanner. Frequencies sometimes change, check with www.trunktracker.com.
• If you have internet access, you can visit www.bc780xlt.com, www.trunktracker.com or
www.bearcat1.com/free.htm for current news and frequency information about Trunk
Tracking Scanning.

Programming and Receiving
Trunked Systems
Programming Trunking Frequencies
The first step in tracking a trunked system is storing the frequencies in one of the 10
available banks in your scanner. Remember that you can only store one trunking system in
each bank.
Important:
If you are programming an EDACS or LTR trunked system, you must enter the
frequencies in a specific order. Check the frequency guide included with the
scanner for the frequencies in your area. For additional frequencies, check the
websites listed on page 5.
1. Press MENU.
2. Press s or t to select TRUNK DATA and then
press E.
3. Press s or t to select the bank no. and then press E.
4. Press s or t to select the TRUNK TYPE and then
press E.
Remember! You can also use the VFO control for scrolling. Also instead of pressing
E, you can press the VFO/SELECT control or press the SELECT/MUTE key.
5. Choose the system you want to track using the
keypad, s or t and then press E.

A tone sounds, and E, M, or L icon appears on the
display according to the system selected.
Note: • To clear a mistake while entering the frequency,
press
(decimal key) repeatedly until the
display is cleared.
• If you enter a frequency which is out of the
system’s trunking range, a distinctive beep
sounds and ERROR appears on the display.
Selecting Trunking Programming Menu Mode
To change the system type which your scanner monitors, you must be in the Trunking
Programming menu mode.
To select this mode, follow these steps:
1. Press MENU.
2. Press s or t to select TRUNK DATA and then
press E.

Setting the Squelch
For trunked reception, a good setting for the SQUELCH control is in the center of the range
with the red marker pointing up. See the illustration.
If set too high (CCW) in some cases it could prevent your scanner from
locking to the control channel reliably. If set too low (CW) it will slightly
delay finding the control channel. The best setting is the same as for
conventional reception, and is not critical.
Receiving Trunked Systems
When you have properly programmed all the frequencies for a trunked system, you can
receive the system several different ways. You will find that Search, Hold, Lockout, Scan and
Manual are all similar to conventional scanning.
TRUNKED SEARCH lets you hear all system talkgroup activity (unit-to-unit I-Calls
may be received as well). This is the best way to get started.
ID HOLD works with Search mode to let you quickly freeze reception on an
interesting transmission. Or you can manually specify a talkgroup with DIRECT
ENTRY ID HOLD.
ID LOCKOUT works with Search to exclude talkgroups that you don't want to hear.
ID SCAN lets you receive only those talkgroups that you store in Scan Lists.
MANUAL lets to selectively listen to a talkgroup in your Scan Lists
When receiving EDACS systems, remember that Uniden's AFS talkgroups give you powerful
flexibility. In a few keystrokes, you can specify a single talkgroup, a fleet, or an entire agency
in all the above modes. Read the section "EDACS Reception" to understand how this works.
Trunked Search
Once you have programmed all the frequencies for a trunked system, SEARCH will let you
immediately start hearing transmissions. It is suggested you try SEARCH mode first.
1. Press SCAN, and select the bank(s) you wish to receive, just as you select banks in
conventional scanning.
2. Press TRUNK to enable trunked reception. The radio will seek and acquire the trunked
system control channel. The scanner will now be in MONITOR mode. You will hear the
control channel and see active talkgroups on the screen. You will not hear the voice
transmissions in MONITOR mode.
+ Hint: MONITOR mode is an excellent way to observe system activity and determine
which talkgroups are most active. Locked-out IDs display during MONITOR mode.
3. Press SRCH to begin searching and receiving. You will hear talkgroups and see them on
the screen.
39
BC780XLT1.qxd
10/08/2000
5:02 PM
Page 40
Talkgroups display differently in Motorola, EDACS and LTR systems. You should read the
appropriate parts of this guide to understand the formats.
The bottom line of the display indicates the Bank and the type of trunked system you are
monitoring. You can change this to display a bank tag by using the System Menu.
Regardless of the system, you won't know exactly who you are receiving until you listen for
awhile, or refer to frequency guides or internet sites such as www.trunktracker.com. Of
course, figuring out who each ID represents is half the fun of TrunkTracking.
Later, when you learn more about a system, you will want to store lists of talkgroups.
Then you can scan specific agencies and users, and use the many other features your
radio provides.
ID Hold and Direct Entry ID Hold Mode
Just like in conventional Search, HOLD lets you pause ID Search on an interesting
transmission without storing the talkgroup into memory.
If you hear an interesting ID during SEARCH mode, and want to continue listening to it -• Press HOLD/s to stop the search. HOLD appears in the display.
If you want to listen to a specific ID, while in HOLD -• Use the keypad to enter the ID you want and press
HOLD/s. HOLD appears in the display.
If you want to stop holding -• Press SRCH to return to Search Mode.
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 L/O when the ID displays.
The ID is locked out. You can lockout up to 200 IDs.
Note: If you lockout an ID in Search mode, it is also locked out in Scan List mode.
Conversely, if you lockout an ID while in Scan List mode, it is locked out in Search
mode. For information about Scan Lists see page 42.
EDACS BLOCKOUT is a powerful form of ID LOCKOUT that can be used only with AFS
and EDACS systems. This feature lets you lock out entire Agencies or Fleets, not just
individual talkgroups. Using ID BLOCKOUT you can, for example, prevent Search from
stopping on any of hundreds of talkgroups in the Utilities agency. You can do this with just a
few keystrokes. To use ID BLOCKOUT just enter the Agency- part, or the Agency-Fleet part,
of the talkgroup code and press L/O. For example, to Blockout Agency 4 in Trunk Search,
press HOLD/s, 04,
(decimal key), and then L/O. For other ways to use partial AFS entry,
be sure to read the section "EDACS Reception".

Restoring Locked-out IDs
To unlock a single ID, follow these steps:
1. Press MENU.
2. Select TRUNK DATA - BANK NO. - L/O ID REVIEW
using s, t or VFO and pressing E, SELECT or VFO.
3. Select the locked out ID you want to unlock using s or t.
4. Press L/O. The ID is unlocked and the next locked ID displays.
To unlock all locked out IDs in a bank at once:
1. Press E instead of L/O in step 4 above.
2. To exit from this mode, press MENU repeatedly.
Channel Activity Indicators
The BC780XLT has 30 Channel Activity Indicators to visually display a trunked systems
activity. You’ll always know which frequencies are in use and how much communication traffic
is occurring.
Each frequency you program in a trunking bank corresponds to an activity indicator at the
top of your scanners display. The way in which the Activity Indicators display provide you with
information about the system you’re tracking.
• The indicator which remains on, even if when there is
no traffic, represents the frequency being used as the
data channel.
• If an indicator turns on and you don't hear a
conversation, then the channel may be used as a
telephone interconnect call (some systems) or a
talkgroup that has been locked out.
• The indicator which flashes when an ID displays
represents the frequency being used by the talkgroup.
• If you're holding on an ID which isn't active, the
activity indicators will turn on and off as other groups
use the system.

Scan Lists
Each bank of your BC780XLT can be a trunk tracking bank and it can be a conventional
scanning bank. When you designate a bank as a trunking bank, your scanner sets up 10
Scan Lists, which are simply lists used to store your favorite IDs. Each list can contain up to
10 IDs, so you can store a total of 100 IDs for each trunk tracking bank. (1000 if you use all
banks as trunking banks!)
Scan Lists help you organize the trunking system users into categories.
For example, you might use List#1 for police IDs, List#2 for fire department IDs, List#3 for
emergency medical service IDs, etc. Once IDs are stored in lists, you can scan them like you
scan conventional frequencies and you can lock out any one (and up to 9) of the 10 scan
lists by pressing the corresponding numeric key. When an ID is active, the scan list number
icon into which it is programmed will flash in the display (when the LIST icon is also active –
see below). You can program your scan lists either manually or during trunking search mode.
SELECT Key
Use the SELECT key while trunking to toggle between viewing the active Banks and the
active Scan Lists. To see which is currently active, check the display for either the BANK or
the LIST icon.
Check the web site www.trunktracker.com or www.bearcat1.com/free.htm for a complete
list of talkgroups for your area that you can program into your Scan Lists.
Programming ID Scan Lists Manually
1. Press MAN, the lowest available ID list number appears on the display.
2. Use HOLD/s and LIMIT/t to select the Scan List
location you want to program.
For example, select the third memory location in the
fifth scan list.
Note: You can also use the keypad to input directly.

Setting Priority in Trunking Mode
You can set priority in your trunking lists, just as you do in your conventional ones. You can
set the priority by pressing and holding PRI for 2 seconds. After you’ve set up your Scan
List, press PRI to activate it.
It’s very similar to conventional priority although there is no “interrupt” during the
transmissions. Priorities are checked in between transmissions.
With Priority on, you can hold on an ID in your Scan List, such as Scan List 6, memory
position 7, and the scanner will check all the priorities in all the active Scan Lists every few
seconds and in between any transmissions on the ID on which you’re holding. The lowest
numbered priority will be checked first. For example, the priority ID in List 1 will be checked
before the priority in List 2, etc.
Note: This function does not work in LTR tracking.
Programming Scan Lists During Search
To select a Scan List location and store an ID during Search mode, follow these steps:
1. When your scanner stops on an ID you want to store,

I-Call (Motorola/EDACS)
I-Calls are direct unit-to-unit transmissions that are not heard by other system users. Your
BC780XLT can receive these transmissions. How you receive I-Calls depends on whether
you are in Search or Scan mode.
During I-Call reception the display will show the Unit ID number of either the transmitting or
receiving mobile unit, not a talkgroup. Unit IDs will display differently according to the type of
trunked system, and will replace the 'n's shown here.
EDACS and MOTOROLA TYPE 1
innnnn
MOTOROLA TYPE 2
7nnnnnn
Hint -- There are thousands of Unit IDs in typical systems, but relatively few I-Calls at a
given moment, so it is normally best to let the scanner to receive any I-Call without trying to
specify particular units.
I-CALLS IN SEARCH MODE
In SEARCH mode, the scanner default is that I-Call reception is OFF. This means that
I-Calls will not be received until you program them to be ON. You have three choices for
controlling I-Call reception. Through the Menu system, go to TRUNK DATA / BANK NO /
I-CALL , and make your selection. The menu choices are:
1 OFF
2 ON
I-CALLs
TALKGROUPS
Not received Received normally
YES
Received normally
3 ONLY YES
NOT RECEIVED
This is the BC780XLT default
Use this choice to receive I-Calls
together with normal
talkgroup traffic.
Use this setting to listen to
I-Calls, and block all talkgroup
reception. For quick access to
this mode, press
then SRCH.
In I-Call ONLY mode, the display will show I-CALL, to warn that only I-Calls will
be received.
You can HOLD any I-Call ID. Because you can only hold on one ID, and there are two IDs
involved in any I-Call communication (the transmitting and the receiving units), you might not
hear the full conversation, but you probably will.
In SEARCH mode, when you hear an interesting I-Call, you can enter the instant
shortcut
then SRCH to enter I-Call ONLY mode. This blocks all talkgroup traffic
and lets you hear just the I-Call. To return to normal reception, you must use the
Menu system to select the ON or OFF option.
Note: When storing I-Call IDs, remember that the ID will be for only one of the units -- either
the transmitting or receiving unit. Unless you specifically want to receive a certain ID,
it might be better to use the special code in the HINT below.

Page 47
I-CALLS IN SCAN AND MANUAL MODE
You can store I-Call IDs in scanlists, just like talkgroup IDs, for use by ID Scan and Manual
modes. To program a specific I-Call Unit ID into a scanlist:
EDACS or Motorola Type 1
Enter
followed by the Unit ID digits, then E.
Motorola Type 2
Enter 7 followed by the Unit ID digits, then E.
HINT - There is a special code to let you receive all I-Call IDs with a single scanlist entry.
Simply enter
, 0, E. This will store the special code i0 in an EDACS scanlist, or
700000 in a Motorola scanlist. Then, whenever you SCAN this entry, or select it in
MANUAL, the scanner will receive any active I-Calls, regardless of the Unit IDs.
Note: Motorola I-CALL tracking performance may vary between systems.
Multi-Track
The BC780XLT allows you to track more than one system at a time. Here are some
highlights of this feature:
You can actually track up to 10 trunking systems at one time.
You can trunk scan or search and scan conventional frequencies at the same time.
You can program conventional frequencies in the same bank as trunking systems.
After the scanner finishes checking a trunked system for activity, it will conventionally
scan the other frequencies in the bank (remember, only trunking frequencies are
programmed in TRUNK mode).
To scan a mix of trunking and conventional banks, select the banks you wish to be active
with trunking off, then press TRUNK. The scanner will instantly begin scanning. If you have
not programmed a trunking bank with talkgroup ID’s, you will receive NO ID (----)
message for that bank. You can switch to SEARCH mode and the scanner will search for any
active ID’s on the system.
Multi-Track Operational Details
When more than one trunk system is active (for example two or more trunked systems or a
trunked system and one or more conventional frequencies), the radio jumps between
systems/frequencies as follows:
TRUNK SCAN: The scanner moves to a trunked system and looks for IDs in your Scan
List(s) for up to one second. If it finds no activity on your programmed talkgroups, it moves
on to conventional channels in the same bank or to the next active bank.
If the scanner finds that a talkgroup in one of your active Scan Lists is on the air, you will
begin to hear that communication and the scanner will of course display the proper
talkgroup number and any alpha tag. When the communication ends, the scanner will wait
for any delay period (such as a default of two seconds) for any further replies and, if none,
the scanner will move to the conventional channels in the same bank or to the next bank.
The scanner will not look for any other IDs within the same trunked system (as this would
slow the scan process). Note that if you press SCAN while you are listening to one ID, the
scanner will check to see if another ID in your Scan List is active. It will disregard the ID to
which you were just monitoring.

TRUNK SEARCH: This mode works similarly to TRUNK SCAN. If the scanner finds any
(non-locked-out) ID when it checks the control channel, you will hear it. You will then hear
any replies that follow within two seconds (or whatever delay you may have set). After that
the scanner will move on and not continuously search the system for additional IDs (on
busy systems you would never leave the system if this were the case). Note that if you
press the SRCH key while monitoring one ID, the radio will check if any other IDs are
active (it will disregard the ID you just left), and if none are active, it will move on.
LIMIT/ t KEY: If you wish to exit a trunked system without waiting for the currently active
talkgroup to finish its communication, press the LIMIT/t key. This is particularly helpful on
very busy systems where many talkgroups are active and activity is frequent and longlasting. Pressing this key will move the scanner on to the conventional frequencies in the
same bank or the next bank.
SCAN & SEARCH Icons
For the first time on a Uniden scanner, you will see both the SCAN and the SEARCH
icons active at the same time. This indicates that the radio is scanning conventional banks
and Trunk searching trunking banks. When the radio is trunking, only the SEARCH icon
will be lit. Note that to start a conventional search, you must place the radio into
conventional manual mode and then press the SEARCH key.
