Multi-Track Operational Details

After the scanner finishes checking a trunked system for activity, it will conventionally scan the other frequencies in the bank (remember, only trunking frequencies are programmed in Trunk mode).

To scan a mix of trunking and conventional banks, select the banks you wish to be active, and then press SCAN. The scanner will instantly begin scanning. If you have not programmed a trunking bank with talkgroup ID’s, you will receive NO ID (----)message for that bank.

You can switch to Search mode and the scanner will search for any active ID’s on the system.

Note: To switch ID Scan or ID Search, press and hold TRUNK in the trunked system.

When more than one trunk system is active (for example two or more trunked systems or a trunked system and one or more conventional frequencies), the radio jumps between systems/frequencies as follows:

TRUNK SCAN: The scanner moves to a trunked system and looks for IDs in your Scan List(s) for up to 1 second. If it finds no activity on your programmed talkgroups, it moves on to conventional channels in the same bank or to the next active bank.

If the scanner finds that a talkgroup in one of your active Scan Lists, you will begin to hear that communication and the scanner will of course display the proper talkgroup number and any alpha tag. When the communication ends, the scanner will wait for 2 seconds for any further replies and, if none, the scanner will move to the conventional channels in the same bank or to the next bank. The scanner will not look for any other IDs within the same trunked system (as this would slow the scan process). If you press RSM while you are listening to one ID, the scanner will check to see if another ID in your Scan List is active. It will disregard the ID to which you were just monitoring.

TRUNK SEARCH: This mode works similarly to Trunk Scan. If the scanner finds any (non-locked-out) ID when it checks the control channel, you will hear it. You will then hear any replies that follow within 2 seconds. After that the scanner will move on and not continuously search the system for additional IDs (on busy systems you would never leave the system if this were the case). If you press the RSM key while monitoring one ID, the radio will check if any other IDs are active (it will disregard the ID you just left), and if none are active, it will move on.

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.
