Conventional radio systems Trunked radio systems Trunked system basics How a trunked system works A real life example Conventional radio systems In a conventional radio system, each group of users is assigned one for simplex systems or two frequencies for repeater systems.
For example, the police in your area might operate on A user selects the channel they want to communicate on and presses the PTT button on the side of their radio. This sends a channel request message to the controller that the user wants to start a transmission on the Talk Group ID the channel that they selected. Their radio is programmed up at the radio shop. In the RadioReference database, you can generally determine the radio system type by looking at the line labeled System Type at the top of the screen inside the red square in the screenshot.
If the System Type line says anything else, then it is not a P25 system even though it might have some P25 channels. Page 50 RadioReference is the ability to tag channels directly on the site and print out a nicely-formatted hardcopy of each system. It makes this task much, much easier. This frees you from having to manually enable and disable systems or channel groups as you change location. To use the geopolitical approach, find the geographical center of the scanning target's territory whether city, county, district, precinct, or other agency jurisdiction , and set these coordinates as your center point location.
Both sites list the latitude, longitude, and height of the antenna, and both sites can map the exact location for you. Combining for Efficiency Because many trunked systems have both multiple antenna sites and multiple agencies with differing geographic boundaries, you may want to combine the approaches: 1.
Use the antenna centric approach at the site level: set the geographic coordinates of the antenna as the central location for each site. It is legal to listen to almost every transmission your scanner can receive.

Privacy Overview. LTR systems typically do not have a dedicated control channel. This type of system encodes all trunking information as digital subaudible data that accompanies each transmission. The frequencies also have to be in LCN Logical Channel Number order or the correct 'slot' for the system to trunktrack properly. Each repeater has its own controller, and all of these controllers are synchronized together.
Even though each controller monitors its own channel, one of the channel controllers is assigned to be a master that all controllers report to.
Each of these controllers sends out a data burst approximately every 10 seconds so that the subscriber units know that the system is there. This data burst is not sent at the same time by all the channels, but happens randomly throughout all the system channels. If you listen to the frequencies of an LTR system in manual mode not trunking , on every channel in the system you will hear this data burst that will sound like a short blip of static like someone keyed up and unkeyed a radio within about msec.
LTR systems are limited to 20 frequencies per system. Close Call Auto Store. See Preset Fleetmaps. See Size Codes. Repeat for each block as needed and you will return to the ' Edit Sys Option ' menu. Note: If you select size code 12, 13, or 14, these restrictions apply:. Since these size codes require multiple blocks, you will be prompted for the next available block. For example, if you assign Block 0 as 12, the scanner prompts you for block 2, the next block available, instead of block 1.
If you assign Block 0 as 14, you would not see another prompt because 14 uses all available blocks. Hold Mode in Function Mode Screen. Band Scope mode is assigned to this search key 3 by default. Search Mode ' SRCH ' shows in the display and the scanner searches and displays the signals of the frequency range in real time. The frequency range is shown in 32 bars determined by the center frequency and span.
While searching, the center frequency icon and the bar which shows the current frequency blink. The scanner starts from the lowest frequency of the frequency range and searches to the highest frequency of the frequency range. If the scanner finds a transmission, the scanner displays the strongest and most current signal level in the bar for each frequency in the range. Max Hold Search Mode ' MAX ' shows in the display and will freeze the signal strength bars at their strongest signals.

Using Startup Keys. Here we go again. Uniden has put out this fabulous scanner that will do a multitude of scanning achievement and you are here to find out how. This scanner is exceptionally harder to program for many even seasoned programmers because there is no printed manual and the CD manual is too cluttered. This manual is a culmination of the Wiki, the CD manual, pages!?
There are quite a few improved and new features the XT has that the T didn't have. Fire Tone-Out will now search and find your tones to program.
You don't have to press and hold the Function button anymore; just press and it will stay in Function mode for 3 seconds like the base models takes a little getting used to if you had the older hand-helds. You can edit the default receive bands of the scanner to better and quicker suit your scanning preferences. For the 'techs', you can now enter your Motorola IDs in hexadecimal format.
Now the annoying stuff. Number tags should be viewed with the rest of the channel info so you can just scroll to them. With Key-Safe Mode you are stuck with just the last mode the scanner was in when you turned off the radio i.
Close Call, Scan, etc. Maybe they should've called it Mode-Safe Mode? Startup Configuration can't be canceled once you start using it; the scanner remembers the last use configuration unless you use another, still scans multiple trunking systems relatively slow even with the hold time set to 0 especially if you have a lot of IDs programmed.
You have to hold on a channel first, to attenuate it. There is no 'per channel' delay; you must set the delay for the whole system all sites, all groups, all channels. Updating the firmware after trying to get it from Uniden's website is still very complicated. And, the biggest complaint was no printed manual.
An overview of the features can also be viewed at my Trunking Radio Comparison Chart page. I have included links to other information in the Wiki not relevant to the operation of the scanner so you can still find the rest of the info such as specs, weather event codes, deciphering trunked systems, etc.
There are better antennas out there to use than the one that comes with the scanner. The stock rubber duck isn't fabulous. You may be able to find others on the web but RS is convenient so you can buy it and take it back in the same day if you don't like it. Read the reviews for each at the site. Dynamically Allocated Channel Memory - organized into 'Systems', 'Sites', within trunking systems , 'Groups' within systems , and channels within groups. Up to systems, 1, total sites max per system , 20 groups per system, and 25, channels max IDs or 1, frequencies per system.
Multi-Site Trunking - lets you program the scanner to share trunked system IDs across multiple sites without duplicating IDs, and turn each site on and off independently so that you can select the best site to scan for your area.
Control Channel Only Scanning - allows you to enter just the control channels to trunktrack a Motorola system and the scanner will find the voice channels. You can assign number tags to systems, channels, service searches, and custom search ranges.
Band Scope Mode - Band Scope mode is a special type of search mode where the scanner displays the strength of any signal it finds. Preemptive Priority - a feature that works on Motorola systems. If the Motorola system has priority channels, and you assign one of those talkgroups as priority in the scanner, then when one of those channels becomes active, the scanner will jump to it even if it is on a different system voice channel i.
Individual Channel Volume Offset - allows you to adjust the volume offset for each channel. Control Channel Data Output - allows the analysis of control channel data without the need to perform invasive modifications to the scanner.
Private Systems - lets you flag a system so that it cannot be read out of the scanner or modified only with optional software. Key Safe Mode - lets you hand the scanner to a novice user and prevent programming from being modified. Location-Based Scanning - using an optional GPS unit you can scan your systems based on a set range from your current location. GPS Location-Based Alerts - notifies you when you are near an area you have programmed as a dangerous road, dangerous intersection, or a general point of interest.
Analog and Digital AGC - helps automatically balance the volume level between different radio systems. Preprogrammed Systems - your scanner is preprogrammed with several conventional and digital agencies covering police, fire, and ambulance. Close Call RF Capture Technology - lets you set the scanner so it detects and provides information about nearby radio transmissions.
Close Call 'Do-not-Disturb' checks for Close Call activity in between channel reception so active channels are not interrupted. You can set up to 10 settings transmit frequency, tone frequencies then select one for standby monitoring. The scanner will also search and display unknown tones. For each alert in the scanner, you can select from 9 different tone patterns, 15 volume settings, 7 colors, and 2 color patterns. Repeater Reverse - allows the scanner to try to switch to the repeater if an input frequency is found.
Broadcast Screen - allows the scanner to ignore hits on known broadcast frequencies including pager frequencies in search and Close Call modes. You can also program up to 10 custom frequency ranges that the scanner will ignore. Text Tagging - you can name each system, site, group, channel, talk group ID, custom search range, location, Tone-Out, and SAME group, using up to 16 characters per name. The scanner also displays the alert type. Multi-Level Display and Keypad light - makes the display and keypad easy to see in dim light using 7 color options and three light levels.
Signal Strength Meter - shows the signal strength for the more powerful transmissions. Quick Search - lets you search from the currently-tuned frequency or channel or enter a frequency and start searching. Automatic Channel Setup - accepts frequencies on any valid channel step, even if it does not fall within the band plan's default steps. Configurable Band Defaults - allows you to set the step 5, 6.
Attenuator - you can set the scanner's attenuator to reduce the input strength of strong signals by about 20 dB per channel, search band, close call band, or trunked system.
Duplicate Frequency Alert - alerts you if you try to enter a duplicate name or frequency already stored in the scanner. Search Lockouts - you can lock out up to frequencies temporary, permanent in search or close call search.
Built-in Battery Charger - allows you to charge the batteries in the scanner with a timer to set up to 16 hours. Channel- a programmed frequency or talk group ID location. Scanning- the process of stepping through conventional channels in groups, which are in programmed 'systems'. Searching- the process of searching for active frequencies in quick search, service, custom search, Close Call search, Search and Store, or Close Call Auto Store.
Function Mode- the mode the radio is in when it's waiting for another key press or scroll. Hold Mode- used for monitoring a single system, site, channel, frequency, or Close Call Hit.
Band Scope Mode- the mode the radio is in while doing a Band Scope search. Tone-Out Mode- the mode the radio is in when it's monitoring paging tones. The scanner's memory is organized in an architecture called Dynamic Allocated Channel memory. Dynamic Allocated design matches how radio systems actually work much more closely and make it easier to determine how much memory you have used and how much you have left. No memory space is wasted.
Since you can only program one trunking system per bank in a traditional scanner, and let's say you only have 10 banks, you can only store 10 trunking systems. Also, since some trunked systems might have hundreds of talk groups you wish to monitor, you might have to enter those systems into multiple banks in order to monitor all the ID's.
Instead of being organized into separate banks and channels, the scanner's memory is contained in a pool. You build the systems and groups then use as much memory as you need in the pool to store frequencies, talk group ID's, and alpha tags. With all previous scanners, you selected banks to scan that had channels stored in them. With this scanner, you select conventional 'Systems' or trunking 'Sites' to scan that have channel 'Groups' stored within the 'Systems'. Conventional systems have frequency groups and trunking systems have ID groups.
For trunking systems, you have to create at least 1 'Site' Motorola and EDACS only or multiple sites first that hold the trunking frequencies for each site. The ID channel 'Groups' stored within the trunking systems can be used with all the sites. You can have total channels per conventional system and up to 'Sites' if you have enough memory.
You can have a maximum of Systems, Sites, and 25, Channels. 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.
The range is typically miles, depending upon the terrain and many other factors. 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 mile radius from the repeater location. Your scanner can receive transmissions that use these codes or more commonly referred to as tone codes.
Some Motorola and EDACS systems covering a very large geographic area use multiple antenna sites that each operate on different frequencies and use the same talkgroup IDs for traffic.
Each site will have its own set of trunking frequencies and is monitored like a single system. Each site can have its own quick key, so you can turn each individual site on or off while you scan. Program your talkgroups into channel groups within that system and all talkgroups in the system are available to every site so they don't have to be reprogrammed for each site.
Since all sites share all the talkgroups within the system, multi-site trunking is much more efficient than programming each site as a separate system. Radio Reference. IDs are what you see instead of frequencies when you monitor a trunking system.
Each format displays and uses talk group IDs in slightly different ways. Type I systems are usually organized with different IDs assigned to different fleets. To properly trunk a Type I system, you have to program the fleet map for the system. Type II IDs are identified by a 5-digit number. Decimal IDs are shown as a decimal number from 0 to I-call IDs are usually 6-digit IDs ex: Note: To view unit IDs you have to turn the option on in the ' Settings ' menu. Note: this applies to a fresh scanner right out of the box or one that has been reset.
Press and hold for about 2 seconds to turn on the scanner. The scanner should start scanning one of the preprogrammed systems after the welcome screen disappears. If the screen is too dark, press to turn on the backlight. Press Hold. Press the scroll control to display the volume level. Turn the scroll control within 10 seconds to adjust the volume. Press the scroll control again to close the volume level or let it disappear after 10 seconds. Press Func then press the scroll control to display the squelch level.
Turn the scroll control counter-clockwise all the way then clockwise until the noise stops, then one notch more. Press the scroll control to close the squelch level. Right away you may want to check these settings in the ' Settings ' menu.
The only things you will be able to scan right out of the box are the preprogrammed systems in the scanner. You will also be able to do a service search , custom search , weather scan , search and store , close call search , or close call auto store.
The scanner's menu lets you select options that let you set up and use the scanner using the Menu key. With Close Call RF capture technology, this scanner will automatically tune to the signals nearest you, so you can keep track of what's going on in your area.
Quick-Key System Access Keys The key system allows you to quickly access the systems you use most often. Simply set up the key to the systems you want to hear. Press them to enable or disable the system. Location-Based Scanning Connect this scanner to a compatible GPS receiver, and it will automatically select programmed systems based on your exact location.
