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
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.

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

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.

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

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.

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.

Setting Up Your Scanner
These guidelines will help you install and set up your new scanner:
• If your scanner receives interference or electrical
noise, move the scanner or its antenna away from the source.
• To improve the scanner’s reception, use an
optional external antenna designed for multi-band coverage. (You can purchase this type of antenna at a local electronics store). If the optional antenna
has no cable, use 50-75 coaxial cable for lead-in. A mating plug might be necessary for the optional antennas.
• Use an optional mono earphone or mono headset
with proper impedance (32 ) for private listening. Read the precautions on the inside front cover of this Owners Manual.
• Do not use the scanner in high-moisture
environments such as the kitchen or bathroom.
• Avoid placing the scanner in direct sunlight or near
heating elements or vents.
