PLAN 2: If the last three digits of frequencies are less than 869.0000 and 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 are less than 866.0000 and 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: In Chain Search mode, Control Channel Trunk is activated in the Menu mode (See page 18). You must choose one of 4 frequency plans. This plan applies only when the scanner searches the 800 MHz range. Since a default plan is automatically used when the scanner searches the 900 MHz range, a user does not need to select a 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 a delay, 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 MHz of Type 1 or Type 2 or 900 MHz) and you do have to program the Control Channel frequency into Memory.

BC250D specifications

The Uniden BC250D is a versatile and powerful handheld scanner that caters enthusiastically to the needs of both amateur radio enthusiasts and professionals alike. With its compact design and extensive feature set, the BC250D stands out in the crowded field of communication devices.

One of its significant features is the 200 channels it can store, making it suitable for various scanning tasks. Users can easily program frequencies across public service and amateur bands, including police, fire, and emergency medical services. The BC250D also supports a full range of frequencies from 24 MHz to 1300 MHz, accommodating diverse communication needs.

The scanner’s advanced trunking capabilities allow users to access trunked radio systems, which are frequently used by public safety agencies and commercial entities. It supports both Motorola and EDACS trunking protocols, making it adaptable to numerous scanning scenarios.

Another key characteristic of the BC250D is its customizable scanning options. Users can set priorities for specific channels, enabling them to focus on the most relevant communications. The scanner also features a "Close Call" technology that detects nearby signals automatically, providing real-time monitoring without pre-programmed frequency setups. This feature is particularly beneficial for catching local transmissions that might not be otherwise listed.

The interface of the BC250D is user-friendly, designed to allow easier navigation through its extensive features. The display is crisp and vibrant, presenting information clearly even in low-light conditions. Additionally, the scanner supports alpha tagging, allowing users to assign names to channels for easier identification.

Powering the Uniden BC250D is an internal rechargeable lithium-ion battery, which ensures longer use without the need for frequent battery changes. Plus, with an included belt clip, it’s easy to carry around, making it perfect for users who are always on the go.

In terms of connectivity, the BC250D's built-in computer interface allows for firmware updates and programming through a PC, enhancing its functionality over time.

Overall, the Uniden BC250D combines advanced scanning technology with user-friendly features, solidifying its position as a reliable scanner for a wide range of applications. Whether for hobbyists or professional users, this scanner delivers performance, flexibility, and ease of use.
