For those who want to stay informed on current events, weather, and traffic conditions within a community, a digital police scanner is an essential piece of equipment. Police scanners actually come in both analogue and digital varieties, but these days digital models have largely overtaken the market. With a digital police scanner, you can experience crystal clear reception, and you will be able to monitor a broader spectrum of channels. This ensures that you will never miss out on an important update. It also means you are less likely to miss out on the chance to help out in a crisis.

What is a Digital Police Scanner?
A police scanner, also known as a “radio scanner,” is a device which allows you to listen in on conversations between police, firefighters, and other emergency responders and agencies near your location. With it, you can monitor trunk systems or single channels so long as they are transmitting in unencrypted P25.
As mentioned previously, there are both digital and analogue police scanners. Most cities are now switching over from analogue to digital, largely to digital phase 2 (more on that later). This allows for better coverage and reliability along with superior voice quality.
Analogue transmissions also cannot be scrambled, whereas digital transmissions can be encrypted. Through digital systems, everyone is also assigned an ID, so it is possible for agencies to identify and remotely disable unauthorized radios. With a digital police scanner, you can listen to digital, analogue and trunked transmissions.
There are two basic types of digital police scanners: handheld and base/mobile.
- Base/mobile: This is a fixed unit which is meant to be mounted in a single location, for example at home or in a vehicle.
- Handheld: This type of digital police scanner is more like a walkie-talkie. You can carry it around with you.
Think about how and where you plan to use your police scanner to choose the right type for your needs.
It is very unlikely for you to run afoul of the law by owning and operating a police scanner. Doing so is completely legal since US airwaves are considered to be the property of the public.
There are however a few legal restrictions on how you use your digital police scanner:
- You may not listen in on cell phone communications.
- You are not permitted to eavesdrop on encrypted communications.
- You cannot listen in on information which might further a crime or lead to financial profit.
- In certain states, you are forbidden from listening to your police scanner while you are driving.
Also note that while you may sometimes be able to help out during a crisis, you should never interfere with emergency workers or block access to a site.
Be aware that the above information is just basic guidelines. It does not constitute legal advice. For that, you must speak to a licensed attorney.
Questions About Digital Police Scanners
What is phase 1 vs. phase 2?
As you now know, there are both digital and analogue police scanners. Digital police scanners were developed after analogue scanners, and come in three varieties: Digital phase 1, digital phase 2, and trunked. This may leave you wondering what the difference is between digital phase 1 and digital phase 2.
Digital phase 1 was created to address the matter of congested analogue channels. Whereas analogue channels were 25 kilohertz wide, digital phase 1 channels were 12.5 kilohertz wide. This doubled the number of available channels. More channels were still required, though, so digital phase 2 was rolled out.
What is digital phase 2?
Digital phase 2 was developed to once again double the number of available channels, offering two within the same 12.5 kilohertz bandwidth. This is accomplished through the use of technology referred to as “Time Division Multiple Access,” or “TDMA.” Technically, there is only one actual channel in use per 12.5 kilohertz, but two conversations may take place on it simultaneously. So it is shared.
Why buy a digital phase 2?
There are a number of different reasons to buy a digital phase 2 police scanner:
- Phase 2 digital scanners have longer battery life, thanks to TDMA technology.
- A digital phase 2 police scanner is backwards compatible with digital phase 1, so you can still communicate with those who are using phase 1 systems.
- With a digital phase 2 scanner, you can hear all agencies, including NOAA, police, rail, aviation, and so on. Why cut yourself out of accessing these channels?
- Digital phase 2 is considered by most to be more user-friendly than phase 1.
- Digital phase 2 really is the future for police scanner technology. More and more agencies and individuals are switching to phase 2. Indeed, in many areas, you cannot hear anything without it.
If you still are on the fence about phase 1 vs. phase 2, you should check this database to see what format of police scanners are being used in your area. In some locations you can still get away with phase 1, but in many, phase 2 is an absolute requirement.
Remember, phase 1 is the past, and phase 2 is the future. So even if phase 1 is still in use in your area, it makes sense to purchase a phase 2 scanner. The phase 1 scanner you buy today may be outmoded in a few years, but the phase 2 scanner you purchase will still be an ideal solution.
What is the warranty?
As with any item of consumer technology, the warranty is another important consideration when shopping for a digital police scanner. The most common warranty is for a year. Some models however may offer an extended warranty which covers more time.
Recommended Features For Digital Police Scanner
Most basic digital police scanners include around 10-20 channels. This is adequate if you will only be listening to a few agencies. If however you will be monitoring many, consider getting a scanner with more channels.
Banks and lists
With these features, you can sort your channels into helpful categories. One example might be “Fire,” while another might be “Police.”
If you are purchasing a digital police scanner with an SD card, you can record conversations. In most cases, you probably will not need more than 2 GB. If however you plan to record hundreds of hours worth of audio, you might need more.
Color screen and touch screen technology
Some digital police scanners have color screens while others do not. The same is true for touch screens. So you will need to decide whether color is important and whether you prefer a touch screen or buttons to control your device.
Both phase 1 and phase 2 scanners may include GPS compatibility (this is more common among phase 2 scanners). With GPS linked up to your digital scanner, the scanner can tell if you have moved to a new area. This allows on-the-fly updating of available frequencies.
This is down to ease-of-use. Some digital police scanner software suites are more user-friendly than others. Reading reviews can help you figure out what is best to buy. Also note that your scanner may be programmable via a PC, but there are currently no Mac-compatible models.
Charging while scanning
While many digital police scanners do not include the capability to charge while scanning, some do.
Before purchasing a digital police scanner, check and see which frequencies are already loaded in (for example USA and Canadian).
The range you see listed for a digital police scanner model is what you can expect at best in clear, unobstructed conditions. Line-of-sight is required for police scanners to send and receive transmissions, so if you are in an area which is forested or mountainous, you will have a hard time getting the full range. The same is true for urban areas. An aftermarket antenna is an option for boosting your effective range.
AA batteries are the standard for use in digital police scanners. Battery life can range, but 8 hours is typical. Using high power batteries may help to extend battery life.
Check the scan and search speed for the model you are thinking of buying. A scanning speed of roughly 16 per second is fine if you only have around 10 channels to scan through, but you should look for a higher speed if you are listening to a lot of channels.
You can also look for a cool feature called “search mode.” This allows you to locate frequencies which are not listed in frequency books and databases (federal agencies sometimes use these). Another search feature to shop for is “service search.” This one makes it easy to search pre-programmed frequencies to find firefighters, police and other services in an area.
Sensitivity and selectivity
Police scanner sensitivity is described in microvolts. High sensitivity helps with listening to weak transmissions. Look for a lower number. This indicates a higher sensitivity. You need higher sensitivity if you are operating in a rural environment.
If on the other hand you are in an urban location, you should look for a scanner with higher selectivity. This makes it possible to pick a specific station even if there is one right next to it on a neighboring frequency. Otherwise, you might not have enough control.
Other useful features
There are quite a few other features which may vary from one police scanner model to the next. Here is a quick rundown of a few of them:
- Trunk tracking: A scanner with a trunk tracking feature is necessary if one of the agencies you want to listen in on is using a trunked radio system in your location.
- Alpha tags: This alphanumeric display system shows you text identifiers for agencies and channels.
- Automatic mode and step selection: Don’t want to manually select the optimum mode and step for every frequency? This feature will do it for you.
- Computer control: Put your scanner under computer control.
- Dynamic memory: A dynamic memory system allows you to customize the sizes of your banks. That way you can shrink some of the bank sizes in order to free up memory.
