What are Highway Patrol Alerts?

Most highway patrol vehicles on the road today are equipped with a secondary radio system known as a “mobile extender” or “vehicular repeater.” Whenever the dispatcher transmits to any vehicle in the district, “mobile extender” in every car within the district is activated.

Using a constant PRIORITY check of specific frequencies in each state, the BCT8 recognizes and alerts you to transmissions from “mobile extender” radios as well as from car-to-car, aircraft-to-car and other special-purpose frequencies. You receive an audible (beep tone) and visual (flashing Alert light) alert whenever you are within an approximate three-mile radius of Highway Patrol/ State Police units using a mobile extender unit.

What is Scanning?

Unlike standard AM or FM radio stations, most two-way communications do not transmit continuously. The BCT8 scans the Frequencies you have programmed into the Scanner’s channels until it finds an active frequency.

Scanning stops on an active frequency and remains on that channel as long as the transmission continues. When the transmission ends, the scanning cycle resumes until another transmission is received.

What is Searching?

The BCT8 can search each of its 13 bands to find active frequencies. This is different from scanning because you are searching for frequencies that have not been programmed into your Scanner’s channels. The scanner automatically chooses between two speeds while searching. During search mode the scanner will search 100 frequencies per second for band with 12.5 kHz steps and during Turbo SEARCH mode the scanner can achieve up to 300 frequencies per second for bands with 5 kHz steps.

What is Trunk Tracking?

Conventional scanning is a simple concept. You enter a radio frequency in your scanner’s memory which is used by someone you want to monitor. For example, the police in your area may broadcast on 460.500 MHz, the fire department on 154.445 MHz, the highway department on 37.900 MHz, etc. So when your scanner stops on a frequency, you usually know who it is, and more importantly, you can stop on a channel and listen to an entire conversation. This type of scanning is easy and fun.

As the demand for public communications has increased, many public radio users don't have enough frequencies to meet their needs, and this has created a serious problem. Trunking radio systems have been implemented to solve this problem.

BCT-8 specifications

The Uniden BCT-8 is a portable scanner that has made a significant impact in the world of communications monitoring. Designed for both amateur enthusiasts and professional users, this device provides a robust set of features, making it an essential tool for anyone interested in receiving and decoding a wide range of radio frequencies.

One of the standout features of the BCT-8 is its ability to scan both conventional and trunked radio systems. This versatility allows users to listen to everything from local police and fire department communications to amateur radio operations and even aviation channels. The scanner operates between 25 MHz and 1300 MHz, covering a wide array of frequencies that cater to diverse listening interests.

The BCT-8 is equipped with a user-friendly interface, featuring an LCD screen that displays clearly readable information such as channel frequencies and descriptions. Additionally, it utilizes a programmable scan feature, enabling users to store frequencies in memory for quick access. This functionality is particularly useful for those who regularly monitor specific channels, saving time and simplifying the scanning process.

Another notable technology in the BCT-8 is its capability to decode CTCSS and DCS tones, allowing users to filter out unwanted signals and focus on the conversations that matter most to them. This feature is particularly beneficial for monitoring crowded frequencies, ensuring that listeners can hone in on their desired transmissions without interference.
