The FCC Wants You To Know This scanner has been tested and found to comply with the limits for a scanning receiver, pursuant to Part 15 of FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This scanner generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that in

Scanning Legally Your scanner covers frequencies used by many different groups, including police and fire departments, ambulance services, government agencies, private companies, amateur radio services, military operations, pager services, and wire line (telephone and telegraph) service providers. It is legal to listen to almost every transmission your scanner can receive. However, there are some transmissions that you should never intentionally listen to. These include: • Telephone conversation

Introduction The BC796D APCO 25 Digital Trunking Scanner connects you to the exciting world of scanning. Capable of scanning conventional frequencies, analog trunking systems, and the most popular digital trunking systems, it is a great all-in-one solution to your scanning needs. Here is a brief list of some of the systems you can monitor with your BC796D: • Motorola Type I, II, IIi Hybrid, and APCO 25 Phase 1 Digital Systems (including 3600 bps and 9600 bps control channel systems) EDACS and ED

Using this Manual To get the most from this manual, review the contents to become familiar with the basic functions available. If you are new to scanning or trunktracking, be sure to read the “Understanding Scanning” section for a quick background on the technology behind the hobby. The first thing you’ll need to do is plug the AC charger into the scanner. See “Setting Up Your Scanner” if you need any help doing this. Next, you’ll want to listen to see what you can hear with your scanner. Insta

Understanding Scanning This section provides you with the 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 to get the most from your BC796D. 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) to use. Any time one of them transmits, their trans

Trunked Scanning While conventional scanning worked great while there were only a few groups wanting to use the frequencies, with the advent of smaller, lower-cost radios more and more agencies and businesses wanted to take advantage of the utility of 2-way radio. As a result, the bands that were used most became full, so new users were not able to take advantage of the technology as quickly as they wanted. Trunking solved this frequency shortage by allowing multiple groups to use the same set o

One big difference you will notice with digital versus analog transmissions, is that with analog systems, you might be able to hear weak signals interspersed with hissing. As you move further away from the system, the interference gradually increases until you are unable to make out the transmission. With digital systems, the cutoff point is much more abrupt. You might have a small area where partial decoding occurs...in which case you will hear partial and garbled audio. However, once the scann

LTR Trunking ® LTR (Logic Trunked Radio) systems are trunking systems used primarily by business or private communications service providers, such as taxicabs, delivery trucks, and repair services. These systems encode all control information as digital subaudible data that accompanies each transmission, so there is no separate control channel. Users on an LTR system are assigned to specific talkgroups, which are identified by the radio as six digit numbers. These numbers are in the form AHHUUU

Getting More Information By itself, this manual really only provides part of what you need to know to have fun scanning – how to program and use the scanner. The two supplied Conventional and Trunking frequency guides will give you a good head start on the other part of what you need to know – what frequencies have interesting content. You can also find a wealth of information on the Internet...check out scanners.uniden.com for the latest frequency information in your area. In addition, you can
