Control Channel Only Mode

When this function is activated, trunking is performed using control channel data only. Voice channel (also known as "working channel") frequencies do not have to be programmed into memory. When using this feature, the scanner will display "CC" and channel activity indicator bars will not operate. This feature only applies to Motorola 800 MHz and 900 MHz systems.

To turn this function on, choose Motorola Type-2 800 MHz or 900 MHz or TYPE 1 by selecting TRUNK DATA - BANK NO. - TRUNK TYPE. Then set to the desired control plan by selecting TRUNK DATA - BANK NO. - CTRL CH ONLY.

You must choose one of 4 frequency plans before you begin to Control Channel Trunk. Note that the default, Plan 1, is the most common. Read the description of the Plans below for details on which may apply for you.

PLAN 1: Use Plan 1 if the last three digits of ALL the frequencies in use end in one of the

following three digits: 125, 375, 625, or 875 (example: 856.1125, 860.7375, 859.6625, 855.8875).

PLAN 2: If the last three digits of frequencies less than 869.0000 end in one of the following three digits (125, 375, 625, or 875) AND if ANY other frequencies end in (000, 250, 500, or 750) use Plan 2.

PLAN 3: If the last three digits of ALL the frequencies in use end in one of the following three digits (000, 250, 500, or 750) use Plan 3.

PLAN 4: If the last three digits of frequencies less than 866.0000 end in one of the following three digits (000, 250, 500, or 750) AND if ANY other frequencies end in (125, 375, 625, or 875) use Plan 4.

Of course you will know the Control Channel frequency itself so that will help you determine the proper Plan. If you try one plan and you receive errors (such as the scanner jumping to channels that are obviously not part of the system), you should try an alternate Plan.

Note: You can assign a fleet map to Type 1 or Hybrid systems scanned in Control Channel only mode by going into the menu. You can also program IDs, set delays, alpha tags and all the other parameters for systems scanned in this mode. You can then either search the system to find new IDs or you can program IDs into memory and then scan them.

Note: The Control Channel Only feature is an extremely powerful tool. You can use it to determine if systems you are familiar with may have added new frequencies or you can use it to discover new systems by simply finding active control channels (using Search) and then programming them for Control Channel operation only. Remember that this feature only applies to Motorola 800 and 900 MHz systems, that you do have to set the menu for the proper system type (800 Type 1 or Type II or 900 MHz) and you do have to program the control channel frequency into memory and press and hold the TRUNK key to identify the frequency as trunked.

BC780XLT specifications

The Uniden BC780XLT is a versatile and popular scanner that has made a name for itself among scanning enthusiasts and professionals alike. Released in the early 2000s, this model is known for its extensive feature set, allowing users to monitor a wide range of frequencies and communications.

One of the primary features of the BC780XLT is its capability to scan multiple frequency bands, including VHF, UHF, and 700/800 MHz frequencies. This makes it an ideal choice for monitoring public safety communications, utility services, and various other two-way radio frequencies. The scanner operates in an impressive frequency range of 25 MHz to 1.3 GHz, allowing users to enjoy a broad spectrum of signals.

The BC780XLT features TrunkTracker technology, which enables it to follow trunked radio systems. This is crucial for monitoring communications from agencies that operate on these complex frequency systems, like police and fire departments. The scanner can decode both Motorola and EDACS trunked systems, providing extensive coverage of public safety communications.

User-friendly controls and advanced features make the BC780XLT accessible for both beginners and experienced users. The numeric keypad allows for quick entry of frequencies, while the large LCD display provides easy visibility of channel information, including frequency and mode. The 10-channel pre-programmed memory allows users to store their favorite frequencies and easily scan between them.

In addition to its scanning capabilities, the BC780XLT also supports close call technology. This feature allows the scanner to automatically detect nearby signals, instantly alerting users to any active frequencies in their vicinity. This is particularly useful for users in urban areas, where multiple frequencies may be in use simultaneously.

The BC780XLT also has a robust battery-saving feature, making it an excellent option for those who need to scan on the go. This functionality, coupled with its ability to operate on AC or DC power, adds to its versatility, ensuring uninterrupted scanning during extended use or in field operations.

In conclusion, the Uniden BC780XLT Scanner stands out for its comprehensive feature set, including TrunkTracker technology, extensive frequency coverage, and user-friendly design. Whether for hobbyists, emergency responders, or professionals needing reliable communication, the BC780XLT continues to be a valuable tool in the world of scanning. Its enduring popularity speaks to its performance and adaptability in a rapidly evolving technological landscape.
