IMPORTANT!
This scanning radio has been manufactured so that it will not tune to the radio frequencies assigned by the FCC for cellular telephone usage. The Electronic Communications Privacy Act of 1986, as amended, makes it a federal crime to intentionally intercept cellular or cordless telephone transmissions or to market this radio when altered to receive them. The installation, possession, or use of this scanning radio in a motor vehicle may be prohibited, regulated, or require a permit in certain states, cities, and/or local jurisdictions. Your local law enforcement officials should be able to provide you with information regarding the laws in your community.
Changes or modifications to this product not expressly approved by Uniden, or operation of this product in any way other than as detailed by this Operating Guide, could void your authority to operate this product.
EARPHONE WARNING!
Be sure to use only a monaural earphone with this scanner. You can also use an optional 32 Ω stereo 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 Ω). 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.

The FCC Wants You to Know

This scanner has been tested and found to comply with
The FCC Wants You to Know
the limits for a scanning receiver, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This scanner generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this scanner does cause harmful interference to radio or television reception, which can be determined by turning the scanner on and off, you are encouraged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna
• Increase the separation between the scanner and the receiver
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
1) This device may not cause harmful interference, and
2) this device must accept any interference received, including interference that may cause undesired operation.

Scanning Legally

Your scanner covers frequencies used by many different groups, including police and fire departments, ambulance services, government agencies, private companies, amateur radio services, military operations, pager services, and wireline (telephone and telegraph) service providers. It is legal to listen to almost every transmission your scanner can receive. However, there are some transmissions that you should never intentionally listen to. These include:
• Telephone conversations (cellular, cordless, or other private means of telephone signal transmission)
• Pager transmissions
• Any scrambled or encrypted transmissions
The FCC Wants You to Know
8
According to the Electronic Communications Privacy Act (ECPA), you are subject to fines and possible imprisonment for intentionally listening to, using, or divulging the contents of such a conversation unless you have the consent of a party to the conversation (unless such activity is otherwise illegal). This scanner has been designed to prevent the reception of cellular telephone transmissions and the decoding of scrambled transmissions. This is done to comply with the legal requirement that scanners be manufactured so they are not easy to modify to pick up these transmissions. Do not open your scanner’s case to make any modifications that could allow it to pick up transmissions that are illegal to monitor. Modifying or tampering with your scanner’s internal components or using it in a way other than as described in this manual could invalidate your warranty and void your FCC authorization to operate it.
In some areas, mobile use of this scanner is unlawful or requires a permit. Check the laws in your area. It is also illegal in many areas (and a bad idea everywhere) to interfere with the duties of public safety officials by traveling to the scene of an incident without authorization.

Understanding Scanning

This section provides you with background on how
Understanding Scanning
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 BC246T.

Understanding the Scanner’s Memory

Your scanner’s memory is organized in an architecture called Dynamic Allocated Channel 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.
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 70 or so 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 sys tems into multiple banks in order to monitor and track all the ID’s.
-

What is Scanning?

Unlike standard AM or FM radio stations, most two-way communications do not transmit continuously. Your BC246T 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
Understanding Scanning
18
cycle resumes until the scanner receives another trans­mission.

What is Searching?

The BC246T can search each of its 21 bands 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 trade marked 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.
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
Understanding Scanning
19
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.
CTCSS Frequencies (Hz)

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
• FRS/GMRS 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.

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 GMRS/FRS radios. The range is typically 1-8 miles, depending upon the terrain and many other factors.
Understanding Scanning
21

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 repeater­based 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 25-mile radius from the repeater location.

What is Trunk Tracking?

Your BC246T is designed to track the following types of 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
When tracking these types of systems, you might want to remember these important points:
• 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
Understanding Scanning
22
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 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 Trunktracking scanner.
Not only does your BC246T 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.
Understanding Scanning
23
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 53, “Program­ming EDACS Systems” on Page 57, or “Programming LTR Systems” on Page 59 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), 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. 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 You can also find fleet map resources on the web.
“Preset Fleet Maps” on Page 103.
Understanding Scanning
24
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 the data as a Type I system with each transmission. Type II systems do not use Fleet-subfleet 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.

/3

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 Agency­Fleet-Subfleet (AFS) hierarchy. Also, there is one variation of EDACS called SCAT that your BC246T 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 ambulance service, 03 by the fire department, and so on. Each agency is then subdivided up to 16 times to provide
Understanding Scanning
25
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 AFS system, your BC246T lets you assign wildcard ID’s that let you, for example, use only one ID memory to identify all units in either an agency or a fleet.
EDACS SCAT – EDACS SCAT (Single Channel Autonomous Trunking) systems operate on a single channel and alternate control data with analog voice traffic. While your BC246T 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)
Understanding Scanning
26
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 BC246T can receive I-call transmissions. See “Setting I-Call (Motorola and EDACS Systems Only)” on Page 68 for more information about monitoring I-call transmissions.

Scanning Systems

To begin scanning programmed systems, press Scan. The BC246T scans all unlocked systems in all activated quick-key groups.
Notes:
• If no systems are programmed, or all systems are locked out, an error message appears. Program a system or select a system to scan.
• When scanning multiple systems, the BC246T scans systems according to the assigned quick key. Systems assigned to quick key 1 are scanned first, then 2, 3, 4, etc. Systems not assigned to a quick key are scanned last. Within a quick key, systems are scanned in the order they were assigned.
• Within a system, channels are scanned according to the assigned channel group, with the same priority as described above for systems.
• The BC246T scans a system for the duration you set using the System Hold Time option (see System Hold Time” on Page 63). For trunked sys­tems, the scanner moves to the next system after the hold time expires, the current transmission ends, and the channel delay expires. Conventional systems

Preprogrammed System Tips

All systems preprogrammed into the scanner are assigned to quick key 9. To turn the preprogrammed systems on or off, simply press 9 while scanning.
Notes:
• The systems preprogrammed into the scanner are located primarily in major metropolitan areas. You might not be able to receive one or more of these preprogrammed systems.
• You might hear transmissions on frequencies assigned to very distant stations. This will happen if a local sys tem also uses the same frequency.
You can scan preprogrammed systems more efficiently by preventing the BC246T from scanning systems that are not in your area. There are three ways to do this:
• Lock out the faraway systems (see “Locking/Unlock­ing Systems” on Page 42).
• Reassign your local systems to another quick key (see
“Editing the System Quick Key” on Page 62).
• Delete the faraway systems (see “Deleting Systems” on Page 70).

Cloning the Scanner

To clone (copy) data from one BC246T scanner to another BC246T scanner, you must first connect the scanners to each other using the included connection cables and a DB9 null modem adapter and DB9 gender changer (neither included), available at most computer stores. Then you must set one scanner as the master (source) and the other as the slave (destination).
Plug the smaller end of each of the included connection cables into Remote on the right side of each scanner. Then connect the other end of the cables together using the null modem connector and gender changer.
Then set up both scanners.

Programming Radio Systems

Your BC246T comes preprogrammed with the major
Programming Radio Systems
analog systems used in the 25 most populous counties in the US. However, to get the most enjoyment from your scanner (especially if you do not live near one of these counties), you must customize the programming for your area.
To edit an existing system, use the menu to navigate to the system setting you want to change. This section assumes you are programming a new system.
Programming radio systems is completed in two major steps. Don't skip either step!

1. Plan the system.

2. Program the system into your scanner according to the plan you prepared in Step 1.

To make planning easier, planning worksheets are included in the back of this manual for each system type. Copy the worksheets (or download this manual from the Uniden America Corporation website and print extra sheets), then use them to plan out how you will program the scanner
Important! Before you start programming your scanner, make sure the batteries are fresh or fully charged. If the scanner loses power while you program it, its memory might be corrupted which will require you to reinitialize it (see “Initializing the Scanner’s Memory” on Page 48). All information prorammed in the scanner, including preprogrammed systems, might be lost.
General Notes
• You can store up to 200 systems.
• Trunking systems can have up to 200 channels each. The number of conventional system channels you can have is limited only by the amount of scanner memory remaining.
• You can store up to 20 channel groups per system.
• Total channels are limited to about 2500.
• Channels that have text tags use more memory than those that do not. If you use a text tag for every channel, total channels are reduced from 2500 (1600 is typical).

scanner so it detects, displays the frequency of, and lets you hear a nearby strong radio transmission. You can set the scanner so the Close Call feature works "in the background" while you are scanning other frequencies, turn off normal scanning while the Close Call feature is working, or turn off the Close Call feature and use the scanner normally.

To turn Close Call detection on or off, press then
. When the feature is on, appears on the display and normal operation is briefly interrupted about every 2 seconds.
Notes:
• The Close Call feature works well for locating the source of strong local transmissions such as mobile and handheld two-way radios in areas with no other strong transmission sources. Several factors affect Close Call performance, however. Performance is increased with higher transmit power, receive antenna tuned to the target band, and a low background RF level. Other than the antenna, you have no control over these factors, but they explain why performance might vary by both location and time.
• The Close Call feature cannot detect satellite dishes or any transmitter with a frequency above or below the frequency ranges listed under Options” on Page 87.
• The Close Call feature works better with some types of transmissions than others. It might not correctly display frequency information for transmitters using a highly directional antenna (such as an amateur radio beam antenna) or if there are many transmitters operating at the same time in the same area.

Note: NOAA broadcasts are continuous broadcasts.
You will only lose reception if you move out of a coverage area. If the signal is lost, the scanner resumes searching for a weather transmission.

Turning Weather Alert On/Off

In weather alert mode, your scanner functions as a severe weather warning radio. This is especially useful when your area is expecting severe weather conditions late at night. When you set the scanner to weather alert mode, it holds on the weather channel, but does not play the channel’s audio. If it detects a weather alert, it sounds a tone, displays information about the weather alert, and turns on the audio so you can hear the weather broadcast.

This setting determines which types of signals will trigger an alert. Select your setting, then press E.
Alert Only - the scanner alerts when it detects the 1050
Hz tone that accompanies all weather alerts.
ALL FIPS - the scanner alerts and displays information about the weather alert when it receives any FIPS code (see
“Programming a SAME Group” on Page 95).
SAME 1-5 - the scanner alerts and displays information about the weather alert when it receives a weather alert signal that includes any FIPS code you have programmed into the specified SAME group.

Programming a SAME Group

You can edit any of the 5 SAME groups in your scanner. Each group can have up to 8 FIPS codes.
SAME (Specific Area Messaging System) is a system developed by the National Weather Service to reduce the number of alerts received by consumers by allowing them to hear alerts only for the county(ies) they are interested in. Each alert contains information about the type and severity of the alert, as well as the specific geographic locations affected by the alert.
The geographic locations are designated using FIPS codes. Each county or parish in the US and its territories are assigned a FIPS code. In addition, certain special regions and wildcard settings can be assigned.
FIPS codes are in the format nSSCCC:
n: A special subcounty designator. For an entire county, use 0.
SS: The state code.
CCC: The county code.

For example, Tarrant County in Texas is assigned to FIPS code 048439.
0 indicates the entire county
48 indicates the state of Texas
439 indicates Tarrant County
To get the FIPS code for your county, visit the National Weather Service web site at http://www.nws.noaa.gov and search for “FIPS Listing”.

Care and Maintenance

Care and Maintenance

General Use

• Turn the scanner off before disconnecting the power.
• Always write down the programmed frequencies in the event of memory loss.
• If memory is lost, simply reprogram each channel.
• Always press each button firmly until you hear the entry tone for that key entry.

Location

• Do not use the scanner in high-moisture environments such as the kitchen or bathroom.
• Avoid placing the unit in direct sunlight or near heating elements or vents.
• If the scanner receives strong interference or electrical noise, move it or its antenna away from the source of the noise. If possible, a higher elevation might provide better reception.
• Also try changing the height or angle of the antenna.

Cleaning

• Disconnect the power to the unit before cleaning.
• Clean the outside of the scanner with a mild detergent.
• To prevent scratches, do not use abrasive cleaners or solvents. Be careful not to rub the LCD window.
• Do not use excessive amounts of water.

Repairs

Do not attempt any repair. The scanner contains no user serviceable parts. Contact the Uniden Customer Service Center or take it to a qualified repair technician.

Birdies

All radios can receive “birdies” (undesired signals). If your scanner stops during Scan mode and no sound is heard, it might be receiving a birdie. Birdies are internally gener ated signals inherent in the electronics of the scanner.
Press L/O to lock out the channel.
