Before you use this scanner, please read and observe
the following.
EARPHONE WARNING!
Be sure to use only a monaural earphone with this
scanner. You can also use an optional 32stereo
headset. Use of an incorrect earphone or stereo
headset might be potentially hazardous to your
hearing. The output of the phone jack is monaural, but
you will hear it in both headphones of a stereo
headset.
Set the volume to a comfortable audio level coming
from the speaker before plugging in the monaural
earphone or a stereo headset of the proper
impedance (32). Otherwise, you might experience
some discomfort or possible hearing damage if the
volume suddenly becomes too loud because of the
volume control or squelch control setting. This might
be particularly true of the type of earphone that is
placed in the ear canal.

Feature Highlights
Understanding Scanning
Understanding Scanning This section provides you
with background on how scanning works. You don’t
really need to know all of this to use your scanner, but
some background knowledge will help you get the
most from your UBCD396T.
Understanding the Scanner’s Memory
Your scanner’s memory is organized in an
architecture called
memory. This type of memory is organized differently
and more efficiently than the bank/channel
architecture used by traditional scanners. Dynamic
Allocated design matches how radio systems actually
work much more closely, making it easier to program
and use your scanner and determine how much
memory you have used and how much you have left.
Instead of being organized into separate banks and
channels, your scanner’s memory is contained in a
pool. You simply use as much memory as you need in
the pool to store as many frequencies, talk group ID’s,
and alpha tags as you need. No memory space is
wasted, and you can tell at a glance how much
memory you have used and how much remains.
Dynamic Allocated Channel
With a traditional scanner, when you program it to
track a trunked system, you must first program the
frequencies. Since you can only program one trunking
system per bank in a traditional scanner, if there were
(for example) 30 frequencies, the remaining channels
in the bank are not used and therefore wasted. Also,
since some trunked systems might have hundreds of
talk groups, you would have had to enter those types
of systems into multiple banks in order to monitor and
track all the ID’s.
What is Scanning?
Unlike standard AM or FM radio stations, most twoway communications do not transmit continuously.
Your UBCD396T scans programmed channels until it
finds an active frequency, then stops on that
frequency and remains on that channel as long as the
transmission continues. When the transmission ends,
the scanning cycle resumes until the scanner receives
another transmission.
Understanding Scanning
16
What is Searching?
The UBCD396T can search 9 service search ranges
and up to 10 bands together to find active
frequencies. This is different from scanning because
you are searching for frequencies that have not been
programmed into the scanner. When you select
frequency bands to search, the scanner searches for
any active frequency within the lower and upper limits
you specify. When the scanner finds an active
frequency, it stops on that frequency as long as the
transmission lasts. If you think the frequency is
interesting, you can program it into the scanner’s
memory. If not, you can continue to search.
What is CTCSS/DCS?
Your scanner can monitor systems using a
Continuous Tone Coded Squelch System (CTCSS)
and Digital Coded Squelch (DCS) system, which allow
squelch to open only when the tone you have
programmed with a specific frequency is received
along with a transmission.
CTCSS and DCS are subaudible tone signaling
systems sometimes referred to as PL or DPL
(Motorola’s trademarked terms for Private Line and
Digital Private Line respectively). CTCSS and DCS
are used only for FM signals and are usually
associated with both amateur and commercial
two-way frequencies. These systems make use of a
special subaudible tone that accompanies a
transmitted signal.
CTCSS and DCS are used for many purposes. In
many cases, CTCSS and DCS are used to restrict
access to a commercial repeater, so that only those
units which transmit the correct tone along with their
signal can “talk” to the repeater.
17
Understanding Scanning
CTCSS and DCS are also used in areas that receive
interference where there are several stations with
output frequencies close to each other. When this
occurs, you might hear multiple communications on
the same frequency. The stations might even interfere
with each other to the point where it is impossible to
clearly receive any of the stations. A scanner
equipped with CTCSS and DCS (like your scanner)
can code each received frequency with a specific
CTCSS or DCS frequency. Then, when you receive
multiple signals, you only hear the transmission with
the CTCSS or DCS tone you programmed. If you do
not receive the correct tone with a signal, the
scanner’s squelch remains closed and you hear
nothing.
You can search for the following CTCSS frequencies
and DCS codes.
Conventional scanning is a relatively simple concept.
Each group of users in a conventional system is
assigned a single frequency (for simplex systems) or
two frequencies (for repeater systems). Any time one
of them transmits, their transmission always goes out
on the same frequency. Up until the late 1980s, this
was the primary way that radio systems operated.
Even today, there are many 2-way radio users who
operate using a conventional system:
•Aircraft
•Amateur radio
•UHF/PRS users
•Broadcast AM/FM/TV stations
•Many business radio users
When you want to store a conventional system, all
you need to know is the frequencies they operate on.
When you are scanning a conventional system, the
scanner stops very briefly on each channel to see if
there is activity. If there isn’t, the scanner quickly
moves to the next channel. If there is, then the
scanner pauses on the transmission until it is over.
19
Understanding Scanning
Simplex Operation
Simplex systems use a single frequency for both
transmit and receive. Most radios using this type of
operation are limited to line-of-sight operation. This
type of radio is frequently used at construction job
sites, and with inexpensive consumer radios such as
UHF/PRS radios. The range is typically 1-12 km,
depending upon the terrain and many other factors.
Repeater Operation
Repeater systems use two frequencies: one transmits
from the radio to a central repeater; the other
transmits from the repeater to other radios in the
system. With a repeater-based system, the repeater is
located on top of a tall building or on a radio tower that
provides great visibility to the area of operation. When
a user transmits (on an input frequency), the signal is
picked up by the repeater and retransmitted (on an
output frequency). The user’s radios always listen for
activity on the output frequency and transmit on the
input frequency. Since the repeater is located very
high, there is a very large line of sight.
Typical repeater systems provide coverage out to
about a 40-km radius from the repeater location.
What is Trunk Tracking?
Your UBCD396T is designed to track the following
types of trunking systems.
•Motorola Astro (APCO 25) trunking systems.
•Motorola Type I, Type II, Type IIi hybrid,
SMARTNET, and PRIVACYPLUS analog trunking
systems, which are extensively used in 800 MHz
communication systems.
•LTR trunking systems
•EDACS SCAT trunking systems
•EDACS trunking systems
Understanding Scanning
20
When tracking these types of systems, you might
want to remember that your scanner can track more
than one trunking system at a time and scan
conventional and trunked systems at the same time.
Conventional scanning is a simple concept. You enter
a frequency used by someone you want to monitor
into your scanner’s memory. For example, the police
in your area might transmit on 460.500 MHz, the fire
department on 154.445 MHz, the highway department
on 37.900 MHz, etc. So when your scanner stops on a
frequency, you usually know who it is, and more
importantly, you can stop on a channel and listen to
an entire conversation. This type of scanning is easy
and fun.
However, as the demand for public communications
has increased, many public radio users do not have
enough frequencies to meet their needs, creating a
serious problem. Trunking radio systems help solve
this problem.
Trunked Scanning
While conventional scanning worked great while there
were only a few groups wanting to use the
frequencies, with the advent of smaller, lower-cost
radios more and more agencies and businesses
wanted to take advantage of the utility of 2-way radio.
As a result, the bands that were used most became
full, so new users were not able to take advantage of
the technology as quickly as they wanted.
Trunking solved this frequency shortage by allowing
multiple groups to use the same set of frequencies in
a very efficient way. While each type of trunking
system operates a little differently (see the next few
sections), they all work on the same basic premise:
even in a system with a lot of users, only a few users
are ever transmitting at any one time.
Instead of being assigned a frequency, as with
conventional systems, each group is assigned a talk
group ID. A central computer controls the frequency
21
Understanding Scanning
each group operates on...and this frequency selection
is made each time a user transmits. So, while on a
conventional system queries, replies, and follow-ups
are all on a single frequency, they could each be on
completely different frequencies on a trunked system.
This semi-random frequency assignment made
monitoring such a system impossible prior to Uniden’s
invention of the TrunkTracker scanner.
Not only does your UBCD396T scan channels like a
conventional scanner, it actually follows the users of a
trunked radio system. Once you know a talk group’s
ID, you won’t miss any of the action.
If you are a new scanner enthusiast, you might want
to read the first part of this manual and use your
scanner in conventional mode before you begin trunk
tracking. Understanding scanning fundamentals and
terminology will make trunk tracking much easier. If
you are already an experienced scanner operator, you
might want to go to “Programming Motorola Systems”
on Page 59, “Programming EDACS Systems” on
Page 63, or “Programming LTR Systems” on Page 66
now.
Types of Trunking Systems
Trunking systems divide a few frequencies among
many different users, but the way that each system
does this is slightly different. This section describes
some of the technical data behind Motorola, EDACS,
and LTR trunked radio systems.
Motorola Trunking
While there are different types of Motorola trunking
systems, they all use the same basic trunking method.
The system consists of one control channel (or as
many as 4 per system but only one is active at any
one time), plus one or more voice channels (typically
10, 20, or 28 total channels). When a user presses
Push To Talk (PTT) to transmit, their radio first sends
their talk group information to the control channel.
Understanding Scanning
22
The computer then assigns that talk group to a
specific voice channel and transmits that data over the
control channel. All radios in that talk group switch
over to the assigned voice channel and the user can
begin speaking.
This all typically takes place in about a second...
the person transmitting hears a beep from their
radio when the channel is assigned and then it is OK
to start talking.
The systems in use are:
Motorola Type I –
the radios send the radio ID, the
fleet and subfleet talk group ID to the control channel
each time they transmit. To program a Type I system,
you need to know the system’s fleet map. The most
common fleet maps are included in “Preset Fleet
Maps” on Page 123. You can also find fleet map
resources on the web.
Motorola Type II –
the radios only send the radio ID
and radio channel code to the control channel. The
central computer keeps a database of radio ID’s and
which talk group is assigned to which channel code
for each radio, so with this system the user’s radio
sends only about 1 /3 the data as a Type I system with
each transmission. Type II systems do not use Fleetsubfleet talk groups; instead they use a 5-digit ID for
each talk group.
Type IIi Hybrid —
these systems support a mix of
both Type I and Type II users. Like Type I systems,
you must know the system’s fleet map to ensure
proper tracking.
Motorola ASTRO 25 (APCO 25) –
these radios are
similar to Type II systems, but send only the radio ID
and radio channel code to the control channel, transmitting voice in digital form.
23
Understanding Scanning
EDACS Trunking
EDACS trunking works in much the same way as
Motorola trunking with a couple of major differences.
In an EDACS system, each frequency used by the
system is assigned a Logical Channel Number (LCN)
so that less data needs to be transmitted by the
control channel. Also, talk groups are assigned in an
Agency-Fleet-Subfleet (AFS) hierarchy. Also, there is
one variation of EDACS called SCAT that your
UBCD396T can monitor.
Logical Channel Numbers –
each frequency used by
the system is assigned an LCN. This information is
programmed into each user radio. When a user
presses PTT, their radio sends their AFS information
to the control channel. The computer then assigns
that talk group to a channel and sends the LCN so
that all other radios in that talk group will switch to the
correct channel. To program an EDACS system in
your scanner, you will need to know both the
frequencies used by the system and the LCN for each
frequency.
Agency-Fleet-Subfleet –
talk group ID’s for EDACS
systems are assigned in a way that makes it easy to
see at a glance the affiliation of the user. Each radio is
assigned a 2-digit agency identifier from 00 – 15.
For example, 01 might be used by the police, 02 by
the ambulance service, 03 by the fire department, and
so on. Each agency is then subdivided up to 16 times
to provide fleet identification, and then 8 more times to
identify subfleets.
For example, the complete AFS for the Police
Department West District’s dispatch channel might be
01-062. 01 identifies the agency as the police
department, 06 identifies the fleet as the West district,
and 2 identifies the subfleet as the dispatch channel.
While these assignments are somewhat arbitrary and
vary from system to system, there are many
resources on the web for finding the assignments for
most systems. Because of the logical hierarchy of the
system, your UBCD396T lets you assign
AFS
wildcard ID’s that let you, for example, use only one
ID memory to identify all units in either an agency or a
Understanding Scanning
24
EDACS SCAT – EDACS SCAT (Single Channel
Autonomous Trunking) systems operate on a single
channel and alternate control data with analog voice
traffic. While your UBCD396T cannot track ID’s in this
system, it can eliminate the control data so that all you
hear is the voice transmissions when you monitor this
type of system.
LTR Trunking
LTR (Logic Trunked Radio) systems are trunking
systems used primarily by business or private
communications service providers, such as taxicabs,
delivery trucks, and repair services. These systems
encode all control information as digital subaudible
data that accompanies each transmission, so there is
no separate control channel. Users on an LTR system
are assigned to specific talk groups, which are
identified by the radio as six digit numbers.
These numbers are in the form AHHUUU, where:
A = Area code (0 or 1)
H = Home repeater (01 through 20)
U = User ID (000 through 254)
When the scanner receives a transmission on a
channel set to the LTR mode, it first decodes the LTR
data included with the transmission. In the ID search
mode, the scanner stops on the transmission and
displays the talk group ID on the display. In the ID
scan mode, the scanner only stops on the
transmission if the LTR data matches a talk group ID
that you have stored in the talk group ID list and have
not locked out.
LTR systems are frequently programmed so that each
radio has a unique user ID.
25
Understanding Scanning
I-Call (Motorola/EDACS)
I-calls are direct unit-to-unit transmissions that are not
heard by other system users. Your UBCD396T can
receive I-call transmissions. See “Setting I-Call
(Motorola and EDACS Systems Only)” on Page 77 for
more information about monitoring I-call
transmissions.
