LASD - Pursuit of Armed Suspect - (12:18)
Los Angeles County Sheriff's deputies pursue an armed with a sawed-off rifle shotgun with a
hostage down rural dirt roads when the pursuit turns into a hostage situation while "Sam"
(Sargent) units respond "Code-3" (lights & siren) with AR-15 Assault Rifles.

A scanner is a radio receiver that can automatically tune, or scan, two or more discrete frequencies, stopping when it finds a sig A scanner is a radio receiver that can automatically tune, or scan, two or more discrete frequencies, stopping when it finds a signal on one of them and then continuing scanning when that frequency goes silent. Many scanners cover the non-broadcast radio bands between 30 and 951 MHz using FM, although there are models that cover more of the radio spectrum and use other modulation types. Early scanners were slow, bulky, and expensive. Today, modern microprocessors have enabled scanners to store thousands of channels and monitor hundreds of channels per second. Recent models can follow trunked radio systems and decode APCO-P25 digital transmissions. Both hand held and desktop models are available. Scanners are often used to monitor police, fire and emergency medical services.

Scanners developed from earlier tunable and fixed-frequency radios that received one frequency at a time. Non-broadcast radio systems, such as those used by public safety agencies, do not transmit continuously. With a radio fixed on a single frequency, much time could pass between transmissions, while other frequencies might be active. A scanning radio will sequentially monitor multiple programmed channels, or search between user defined frequency limits. The scanner will stop on an active frequency strong enough to break the radio's squelch setting and resume scanning other frequencies when that activity ceases.

Scanners are used by hobbyists, railfans, off duty emergency services personnel, reporters and corporate spies.

Scanners first became popular and widely available during CB Radio's heyday in the 1970s. The first scanners often had between four and ten channels and required a separate crystal for each frequency received. Modern programmable scanners allow hundreds or thousands of frequencies to be entered via a keypad and stored in various 'memory banks' and can scan at a rapid rate due to modern microprocessors.


A hand-held wide band communications receiver.Many recent models will allow scanning of the specific DCS or CTCSS code used on a specific frequency should it have multiple users. One memory bank can be assigned to air traffic control, another can be for local marine communications, and yet another for local police frequencies. These can be switched on and off depending on the user's preference. Most scanners have a weather radio band, allowing the listener to tune into weather radio broadcasts from a NOAA transmitter.

Some scanners are equipped with Fire-Tone out. Fire tone out decodes Quik call II tones and acts as a pager when the correct sequence of tones is detected.

Active frequencies can be found by searching the internet and frequency reference books or can be discovered through a radio's search function. An external antenna for a desktop scanner or an extendable antenna for a hand held unit is a good idea for optimum performance

@username2153 here is their link look up trunking that's what i use if it is out of your price range i will see what i can do as far as if i still have any that i can mail out to you. but what ever works for you.

[teentech101]

@username2153 possession of a controlled substance or paraphernalia (drugs)

@Rocket11213 i agree with you, however i think that radio shack sells them for use at an office or at home but i have bought ones with mobile capability such as car boat helicopter ect. so i would check state laws and then take it up with radio shack or sue them if you get pulled over with one of their scanners in your car just saying.

@username2153 well me personally i would go with a hand held digital scanner from Uniden i have one and it works great. the reason i say that is they have great volume and service and the good part is you can easily hide them. i wouldnt worry to much about the legal part unless you have poss. of con subb. paraphernalia. I highly doubt that they would be doing random searches. but check with the state laws idk about mobile but its not illegal in a office or at home so.

[teentech101]

@username2153 idk where you heard that but i have one in mine try radio shack if not i can help you from there
