Understanding Scanning

This section provides you with background on how scanning works. You don’t really need to know all of this to use your scanner, but some background knowledge will help you get the most from your UBC3500XLT.

Understanding the Scanner’s Memory

Your scanner’s memory is organized in an architecture called Dynamic Allocated Channel 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 pool. You simply use as much memory as you need in the pool to store as many frequencies and alpha tags as you need. No memory space is wasted, and you can tell at a glance how much

memory you have used and how much remains.

What is Scanning?

Unlike standard AM or FM radio stations, most two- way communications do not transmit continuously. Your UBC3500XLT scans programmed channels until it finds an active frequency, then stops on that frequency and remains on that channel as long as the transmission continues. When the transmission ends, the scanning cycle resumes until the scanner receives another transmission.

What is Searching?

The UBC3500XLT can search each of its bands and up to 10 bands together to find active frequencies.
