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 UBC92XLT.

What is Scanning?

Unlike standard AM or FM radio stations, most two- way communications do not transmit continuously. Your UBC92XLT 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 UBC92XLT can search for active frequencies. This is different from scanning because you are searching for frequencies that have not been programmed into the scanner. When you select frequency bands to search, the scanner searches for any active frequency within the lower and upper limits you specify. When the scanner finds an active frequency, it stops on that frequency as long as the transmission lasts. If you think the frequency is interesting, you can program it into one of the banks. If not, you can continue to search.

Conventional Scanning

Conventional scanning is a relatively simple concept. Each group of users in a conventional system is assigned a single frequency (for simplex systems) or two frequencies (for repeater systems). Any time one of them transmits, their transmission always goes out on the same frequency. Up until the late 1980’s

UBC92XLT specifications

The Uniden UBC92XLT is a powerful and versatile handheld scanner designed for both novice users and seasoned enthusiasts who want to monitor a wide array of frequencies. This model stands out with its blend of advanced features, user-friendly interface, and exceptional performance in the field of communications monitoring.

One of the standout characteristics of the UBC92XLT is its frequency coverage. It encompasses a vast range of frequencies from 25 MHz to 1.3 GHz, making it capable of receiving a broad spectrum of signals. Users can listen to civilian aviation, marine communications, amateur radio, and public safety channels. This extensive coverage is accompanied by 100 pre-programmed channels, allowing users to quickly find and listen to popular frequencies without any hassle.

The scanner features a large LCD display, which shows frequency information and other relevant data in an easy-to-read format. This display enhances the user experience by simplifying navigation through channels and settings. Additionally, the UBC92XLT includes a backlight, making it convenient to use in low-light conditions.

Another technological highlight of the UBC92XLT is its use of the Close Call feature. This innovative technology allows the scanner to detect and tune into nearby transmissions automatically. It is an excellent tool for discovering active frequencies, particularly when users are in unfamiliar locations or want to monitor local communications quickly.

The scanner is equipped with a built-in comprehensive memory system, enabling users to store up to 500 frequencies in its memory banks. This feature allows for easy organization and quick access to frequently used channels. The user-friendly programming system also supports convenient scanning, with the ability to select specific banks or skip unused frequencies depending on the user’s preference.

The UBC92XLT also supports CTCSS and DCS decode, which enhances its capability to filter out unwanted signals and focus on relevant communications. This characteristic is particularly useful in crowded frequency bands where multiple transmissions can occur simultaneously.

Furthermore, the Uniden UBC92XLT boasts a robust, portable design, making it ideal for on-the-go use. With its ergonomic grip and lightweight structure, users can easily carry it for outdoor adventures, road trips, or local events.

In conclusion, the Uniden UBC92XLT is a standout handheld scanner that offers excellent frequency coverage, user-friendly features, and advanced technologies. Whether you're a hobbyist or a professional, the UBC92XLT is a reliable tool for monitoring communications with ease and efficiency.
