Understanding Scanning and the UBCD996T

This section provides you with additional background on how scanning works and

how your scanner provides that feature. You don’t really need to know all of this to

use your scanner, but some further background knowledge will help you get the

most from your UBCD996T.

Your scanner’s memory is organized in an architecture called

memory. This type of memory is organized differently and more efficiently

than the bank/channel architecture used by traditional scanners. Dynamic Allocated

design matches how radio systems actually work much more closely, making it

easier to program and use your scanner and determine how much memory you

have used and how much you have left.

Instead of being organized into separate banks and channels, your scanner’s

memory is contained in a . You simply use as much memory as you need in the

pool to store as many frequencies, and talk group ID’s as desired. No memory space

is wasted, and you can tell at a glance how much memory you have used and how

much remains.

With a traditional scanner, when you program it to track a trunked system, you must

first program the frequencies. Since you can only program one trunking system per

bank in a traditional scanner, if there were (for example) 30 frequencies, the

remaining channels in the bank are not used and therefore wasted. Also, since some

trunked systems might have hundreds of talk groups, you would have had to enter

those types of systems into multiple banks in order to monitor and track all the ID’s.

Traditional “Banked” scanners let you select and deselect banks by pressing a single

digit on the keypad. The UBCD996T uses a similar method to turn on and off

scanning sites and systems. When you program a system or site, you assign a quick

key (System/Site Quick Key, or SQK) from 0 to 99. You can use the same quick key

for multiple systems, so that the systems are turned on and off together. To turn a

system/site on or off, just press the digit corresponding to the assigned SQK. For

two-digit SQK’s, first press , then enter the two-digit SQK.

The UBCD996T lets you assign another quick key to a group of channels within a

system. This group quick key (GQK) can be from 0-9. To turn on and off channel

groups, you press while the scanner is scanning the system containing the

channels, then press the GQK within 2 seconds. Systems can have up to 20

channel groups, and multiple channel groups can be assigned to the same GQK.
