What is a Police Scanner?
If you want to be able to monitor radio communications between police and other emergency responders in your area, then you need a police scanner. A police scanner is a wireless device that can pick up a number of different radio bands at the same time. Police scanners are also known as “radio scanners,” “race scanners,” and “channel scanners.”
How Radio Scanners Work
If you understand how an AM/FM radio works, you basically understand how a radio scanner works. AM/FM signals are broadcast through the air on radio waves. So are the signals that go to your television, cell phone, and CB radio.
Radio scanners allow you to pick up more signals within the VHF to UHF range. This gives you a chance to listen in on conversations between emergency workers, sanitation workers, and others in your community.
What You Can Hear
While radio scanners are colloquially referred to as “police scanners,” you can pick up a lot more than just that. With your scanner, you can listen in on:
- Police, sheriff, and highway patrol
- Paramedics and rescue squads
- Security workers
- Road and street departments
- Other federal, state and county agencies
- Helicopters and airplanes
- School systems
- Malls and retail outlets
- Utilities workers
- Stadiums, race car drivers, and pit crews
- Ham radio operators
- And much more!
Why Listen to Scanners
If you have never owned a police scanner, you may wonder why you would want one. There are so many answers to that question! For one thing, you can follow up-to-the-instant information on local emergencies—everything from criminal manhunts to natural disasters. For another, you will always know the state of the roads and the weather—which is useful even when nothing is going on. When your neighbors want information, they will turn to you first!
Users and Uses
Who uses police scanners?
- Patrols and dispatch centers
- News media reporters and videographers
- Home users and radio hobbyists
- Corporate security workers
- Military and government agencies
- Public building workers
- School systems
- Neighborhood watch
Basically, anyone involved in emergency response or communications infrastructure may use radio scanners—plus anybody in the area who is simply curious.
Originally, radio was limited to fixed-frequency models. But in the 1960s and 70s, CB radio was developed, offering from four to 10 channels. In the wake of CB radio, police scanners rose into popularity. Whereas old-fashioned CB radios needed separate crystals to receive each frequency, modern radio scanners use microprocessors. This has allowed for the addition of hundreds of frequencies!
Very few listeners on police scanners run aground of the law. Generally speaking, most communications are legal and safe to listen to.
Here are communications you CANNOT legally listen to:
- Cell phones
- Encrypted communications
And here are uses that are also ILLEGAL:
- Listening while driving in states that restrict it
- Listening for information which will aid in criminal activity or financial gain
You also must not interfere at emergency sites as you could block access or otherwise slow down respondents.
Please note that none of the above information constitutes legal advice. If you have any specific questions or concerns, consult with a licensed attorney.
There are two common configurations for radio scanners:
Base and mobile scanners are both designed to operate from fixed locations. In the case of a base-only/”desktop” scanner, you hook it up to house power and leave it there. In the case of a mobile unit, you mount it in your vehicle, usually in the dash where your stereo would otherwise live. Base and mobile scanners have large antennas and offer you more power and range than handheld models.
A handheld police scanner is portable and small. You can carry it around or clip it to your belt. Some models are small enough to fit in your pocket. They operate on batteries (often rechargeable), and have a lower range than base and mobile models. You can purchase a larger aftermarket antenna to extend the range of your handheld scanner.
Different scanners cover different frequencies—and different agencies utilize different frequencies. Before you buy a radio scanner, you need to look up the frequencies used in your area by the agencies you are interested in following. RadioReference is a great site for this.
If your radio system uses a single frequency for each communication channel, it is a conventional radio system. You cannot use a conventional radio scanner to listen to a trunked conversation.
With a trunking radio system, a large number of agencies can utilize just a few radio frequencies. This allows for sharing in congested circumstances. As you might expect, trunking is common in urban areas.
Trunking systems can pick up conventional signals, but conventional systems cannot pick up trunking signals.
These are the most common, basic, and inexpensive models of radio scanners available. Analog models are more commonly used in rural communities and smaller towns. Note that an analog scanner will not work to pick up signals which are being transmitted on digital systems. Before purchasing an analog scanner, always check to make sure that that is what is commonly in use in your community.
Most larger cities have switched over from analog scanners to digital systems. These systems have better reception and sound quality. Even though digital scanners are more expensive than analog ones, you will need to shell out the extra money to purchase one if that is what is commonly in use in your area.
What features are important to look for in a police scanner? Below is an overview that will help you make the right choice when you are making your product comparisons.
How many channels you need depends on how many agencies you are interested in listening to. A basic model with just 10 to 20 channels will be sufficient if you only want to monitor one or several agencies. If you’d like to listen to a large number of agencies, aim for a model that includes a larger number of channels.
Banks & Lists
This feature allows you to organize large numbers of channels into simple categories called “banks.” Examples might include Aircraft or Fire. If your scanner includes Dynamic Memory Allocation, you may also have what is known as Scan Lists. These are very similar to Banks, except that you have control over the number of channels in each.
While you can find the frequencies for many agencies in frequency books, many others are unlicensed or simply unpublished. This feature allows you to search for these frequencies. This is a great way to follow federal government agencies or US Park Service.
Scan and Search Speed
This is a measure of how quickly your device can scan through channels. If you have a large number of channels to scan through, high speed can be important. If you are only listening to around 10 channels, look for a scanning speed of about 16 per second. If you have more channels to scan through, you might want to consider a higher search speed like 50 or 100 channels per second.
You can use this feature to search through pre-programmed frequencies. This can be a quick and easy way to locate the appropriate frequencies for police, firefighters, and so forth. You will find that it is especially handy for traveling.
If an agency that you wish to follow in your area is making use of a trunked radio system, you will need to purchase a scanner which includes a trunk tracking feature.
Many trunking scanners now include this feature for alphanumeric displays. It provides you with useful text identifying various channels and agencies.
Mode and Step Selection
Your scanner will probably include a feature which allows it to automatically select the right mode for any given frequency. This feature allows you to manually override the selection for mode and step if necessary.
This specification is measured in microvolts. The lower the number, the more sensitive the receiver is. You want a higher sensitivity, because then you will be able to listen to signals even if the transmission is weak. This is particularly useful if you are monitoring aircraft, or live in a rural environment.
If you live in an urban environment, selectivity is an important feature. With it, even if there are two stations on adjacent frequencies, you will be able to pick the one you want to listen to.
This feature gives you the option to put your radio scanner partly or completely under computer control. You may also have the option to download additional frequencies.
This feature givens you a heightened level of control over your banks. With a fixed memory scanner, all your banks are the same size. That means that if you do not fill all the slots in the bank, the remaining memory slots are wasted. With a dynamic memory system, you can customize bank sizes so that you have smaller banks when you need them. That frees up memory for additional slots in larger banks.
Radio scanner controls may vary from model to model, but most of them have the following:
- Volume. This is self-explanatory.
- Squelch. This suppresses static.
- WX button. With this button, you can do a quick check of NOAA weather channels and other pre-programmed frequencies.
- Number Keypad. You can use this to punch in frequencies.
- Search button. Use this to hunt for unknown frequencies.
- Manual button. Step through channels one by one.
- Scan button. Allow the scanner to loop through all of your banks to detect active signals. As each ends, it will move onto the next.
- Delay button. This enables a brief delay on each frequency in scan mode.
- Lockout button. This will prevent the scanner from halting on a particular frequency which you have specified.
