Some wide coverage systems use multiple system sites that are linked together to provide extended area coverage. Each site operates on its own set of frequencies, but share talk group channels with all other sites in the system.

Normally, a site will only carry traffic for talk groups that have at least one subscriber unit (mobile radio) affiliated with it.
 
 
 
With the initial implementation of dynamic memory, each site needed to be entered as its own system, and all talk group channels had to be duplicated. This resulted in more complexity in programming as well as more memory usage.
 
 
 
Multi-Site Trunking is available for Motorola and EDACS system. With this method, you define a system, one or more sites for the system, and then the channels for the system. All channels are shared among all sites.

  • Non-Radio Location-Based Features – the scanner can include location alerts (that sound alert tones when the unit approaches a defined latitude/longitude) and speed-trap alerts (that sound alert tones if the unit is traveling at > than a set speed limit while it is within a grid area).
  • GPS Display Mode – displays location and travel information based on the GPS input.

GPS Features

The scanner will not include a GPS Receiver, an add-on GPS receiver will be required. Users will be able to define a LAT/LONG centerpoint for any system (conventional or trunked) and a range (in miles) that specifies the radius of a circle that specifies where to turn the system on/off.

With the release of the scanner, the radioreference.com database (RRDB) will have the ability to store the Lat/Long/Range settings for conventional subcategories and trunked system sites.

Advanced (and much requested) Features

Multi-Site Trunking

See Uniden Multi-Site Trunking.

Temporary Lockout

Pressing L/O one time while on a channel temporarily locks out that channel. Pressing F+L/O one time while on a system temporarily locks out that system.

Pressing L/O or F+L/O two times results in a permanent lockout. Pressing L/O for more than 3 seconds unlocks all channels in the current system (or all search lockouts if in a search). F+L/O for more than 3 seconds unlocks all systems.

Temporary lockouts are removed when power is cycled.

Startup Configuration

Pressing a number button while powering on the scanner automatically unlocks all systems assigned to that startup key and automatically locks all systems assigned to a different startup key (unassigned systems are not affected).

Location-Based Scanning (GPS)

(also see Population Area Centerpoint)

If you connect a GPS unit to the scanner, it can automatically enable/disable systems based on the geographic information you provide:

  • Latitude (center of the range)
  • Longitude (center of the range)
  • Range (radius of a circle around the Latitude/Longitude) which can be selected from .5/1/3/5/10/20/30/50 miles

Rather than center the lat/lon on the antenna site for the system and set the range to the receivable range for the system, it makes more sense to center these settings on the geopolitical center of the system, and bound the range to encircle that entity. That is, while I can technically hear the Arlington TRS from west Fort Worth, I don’t really want to. Instead, I’d set the lat/lon/range values to approximate a circle around the Arlington city limits so that I would not hear Arlington until I approached/entered Arlington.

Also, not all geopolitical areas are perfect circles. You can modify the shape of the system by entering multiple sites for the system (even though the system might have only one site) and use different location settings for each site. For example, stack two circles to make a tall, narrow scan area for the system.

Non-Radio Location-Based Features (GPS)

There are non-radio type systems that hold other location based information:

(also see DRD DXG POI)

  • Dangerous Xing (DXG): Stores location, range, direction of travel. If you are within range, traveling in the specified direction, you receive an alert.
  • Dangerous Road (DRD): Stores location, range, speed. If you are traveling at a speed greater than the one specified, and are within the range of the specified location, you receive an alert.
  • Points of Interest (POI): Stores location and range. If you approach the specified location, you receive an alert.

In general, a location alert can have:

  • Latitude
  • Longitude
  • Speed (optional)
  • Alpha (optional)
  • Alert Type and Level (optional)
  • Vector (optional)
  • Heading

Alerts are based on:

  • Speed setting > 0 and no vector entered, non-directional speed alert
  • Speed setting > 0 and a vector is entered, directional speed alert
  • Speed = 0 and vector is entered, dangerous intersection alert
  • Speed = 0 and no vector entered, point-of-interest alert

The user can quickly save a location by pressing GPS. Scanner prompts for the type of location to store (Speed, Intersection, or POI).

Close Call Do-Not-Disturb

When set in this mode, the scanner will periodically make Close Call checks whenever the scanner is not receiving audio in another mode. This eliminates the annoying breaks in conversation while still allowing for the Close Call functionality.

“Soft Search Keys

Let you program the keypad’s secondary functions to turn on/off specified search ranges.

Three-Level Backlighting

Lets you set the display/keypad backlight to any of three levels (or off).

Single-Handed Function Operation

Tap Function to access F+ key presses. 5 seconds after your last key press, the scanner reverts to non F+ entry (or press Function again to revert sooner).

Close Call Temporary Store

When this option is turned on, when the scanner gets a Close Call “hit", it temporarily saves the hit and includes that frequency when scanning. The scanner keeps the last 10 hits (older hits are erased by newer ones). Hits are lost when power is cycled. You can store a hit into memory by pressing “E" when on that frequency.

Alert +

Sets the scanner for "wife and girlfriend" mode. Silences all channels and audio except for those channels and events that have an assigned alert.

GPS Display Mode

Lets you display extended GPS information like:

  • Distance to POI
  • Heading to POI
  • Time to POI
  • Speed
  • Position
  • And so on

Dual Serial Ports

Front-set serial port using the same connector as BC246T/BCD396T/BR330T/SC230. Rear DB9 Male connector (for convenient direct plug-in of GPS Serial cable).

Either port can be configured to be PC interface or GPS interface.
