By using a radio scanner you can stay updated on the latest events which include daily news that could directly affect you such as the weather forecast or the traffic condition. These tools allow you to monitor a broad range of channels some of which can be used within a specified area and during a disaster in order to reach out for help or even answer a call for aid.
These scanners, commonly referred to as Police Scanners, come in both analogue and digital form however, the latter will offer an improved reception and it’ll give you access to more channels. Nowadays, everyone goes for the digital scanner but it’s important to understand how this piece of equipment works so you could choose the right one for you and benefit from it in every way possible.
What is a Radio Scanner?
In simple terms, the radio/police scanner gives you the ability to tap in on back and forth conversations that could be taking place between police officers, firefighters, or any emergency agencies that are geographically close to your location. As long as they’re using an unencrypted P25 you can listen to single channels and trunk systems.
That’s not all, they offer a better audio quality than the usual walkie talkie sets in addition to larger area coverage. As previously mentioned, most users are now preferring a digital scanner over the analogue but the second option cannot be scrambled whereas you can add an encryption to the first one.
By using the digital police scanner, you will be assigned a specific ID but this means that some governmental organizations can identify you and later on remotely disable your access if proven to be unauthorized.
Different types of Digital Police Scanners
Since this is the more commonly used form of radio scanners in today’s world, you should take the time to learn all about it before moving on to placing a purchase.
You can start by differentiating between the two common types but you should also consider the reason behind your purchase since it can help you know which one you actually need.
Mobile/Base scanner
This type can be fixed at home or in a car. You can definitely change its place but you won’t be able to use it while doing so.
Handheld scanner
No matter where you go, you can take this one with you since it’s portable. It’s quite similar to a walkie talkie in terms of shape and size but offers better features.
Are Police Scanners legal?
This question is pretty common because some people tend to believe that a “Police” scanner can only be used by specialized services or agencies but this is absolutely not the case. You can own and use one in a perfectly legal way inside the USA since all airwaves belong to the public.
However, it’s important to note that you should not in any way interfere with emergency responders by blocking a certain channel, especially during a crisis or a natural disaster. Keep in mind that you should consult a licensed attorney in case you want to learn more about the legality of usage of this equipment.
With that being said, here are some useful tips on how to avoid legal issues while using these products:
- Do not eavesdrop on private cell phone or encrypted communications.
- Do not listen to communications involving any criminal activity.
- Do not tap in to police scanners while driving. (This is only applicable in some states in the USA)
Difference between phase 1 and phase 2 Radio Scanners
It goes without saying that analogue scanners came first and they use channels that are 25 KHz wide but in order to cope with the ever-increasing demand, the new digital radio scanners were presented in three different variations.
The first one, known as Digital Phase 1, used channels that are 12.5 KHz wide which increased the available channels by doubling them but it doesn’t stop there since more people means that additional channels are required. This lead to the introduction of Digital Phase 2 and Trunked scanners. The latter allows its users to access certain frequencies simultaneously thus creating a talkgroup allowing several individuals to communicate on a single channel.
Digital Phase 2 and Time Division Multiple Access (TDMA)
The point of the Digital Phase 2 was not to double the channels like its predecessor but it used to same 12.5 KHz bandwidth and added a technology known as TDMA which allowed users to have two different conversations on the same channel by literally sharing it.
Should I buy a Digital phase 1 or 2?
Most locations around the world today started using the Digital Phase 2. Even if you find out that the other option is more popular in your area, purchasing the Phase 2 is definitely the right choice since it’s the future of Radio Scanners unlike the outdated Phase 1.
Moreover, several other functionalities make the Phase 2 more sought after than its predecessor:
- You’ll still be able to contact people who are using a Digital Phase 1.
- The previously mentioned TDMA technology gives these scanners additional battery life.
- Most users report that the phase 2 is easier to operate than the older versions.
- You can access almost all of the channels, some of which used by governmental agencies like the police, aviation, and even NOAA.
- Soon enough everyone will be transferring to phase 2 which means that if you still have the phase 1 you will slowly lose contact and not just with agencies but with other individuals in your area.
The most important features in a Digital Police Scanner
Just like every other product, an efficient radio scanner should include certain necessary functionalities.
Search and scan
As you know, you will be browsing through different channels which means that the search and scan speed is important in order to check out the highest number of frequencies in the fastest time. You can start with a scanning speed of 16/second but if you’ll be listening to more than 10 channels then you’ll require something faster.
You can also look for a feature called Search mode which allows you to tap in to frequencies that can’t be found in the usual databases. Moreover, the Service search functionality can be very useful when you’re trying to find frequencies that belong to emergency services.
Selectivity and sensitivity
High selectivity is really useful when you’re locating a specific frequency in an urban area. It might be difficult to find it because of the congestion but if you have the high selectivity option, you’ll be able to choose that station even if it has different channels surrounding it.
As for sensitivity, the lower the number the better! This will allow you to catch all kinds of transmissions, even the weakest ones. This can be very helpful if you’re far from civilization. In other words, when you’re packing your survival gear for a rural expedition, make sure you have a scanner with this feature.
Battery life
There’s no specific range for a battery life since it can hugely differ based on the quality of the batteries themselves. You should be able to use your scanner for a period of 6 to 8 hours. AA batteries are the usual choice but you can also go for something with a higher power.
Channels
If you want to tap in on a couple of agencies then a basic police scanner is enough since it offers 15 channels on average. If that’s not what you want then rest assured that other scanners offer a larger number of channels.
Range
The range you find written on the box is the best you can get since obstructions like buildings or trees can affect the signal. Don’t worry though, you can easily improve the built-in range by purchasing an antenna.
Lists and banks
Some scanners give you the opportunity to distribute and save your channels in order to access them in an easier way. For example, you can add all the channels reserved to emergency services in a single list.
Preloaded frequencies
While shopping, you might notice that certain radio scanners are already equipped with frequencies of a specific country or area. Make sure you buy the one you need since it makes everything a lot easier.
Storage capacity
If you’re looking to record the conversations then you’ll definitely need a scanner with a slot for an SD card. Audio files are generally small in size which is why you can go for the 2 GB card.
Software
The best way to learn about the software of a police scanner is to read online reviews when researching the product. You can find out which models are more user-friendly than others. In addition, you can learn which ones can be programmed through a computer. It’s important to note that no models are compatible with a Mac.
GPS compatibility
Most scanners include this feature but it’s more abundant in those with the Phase 2 criteria. This feature can help you identify available frequencies when you venture into a new zone.
Warranty
This is not specific for Radio scanners but it’s advised that you buy every product with a warranty. Usually, a scanner is covered for a 1-year period but some companies offer an extended warranty.
Additional useful features for a police scanner
Now that the necessary features have been discussed, you can still find other functionalities that can make the scanner more appealing and user-friendly.
Color and touch screen options
This is not a crucial feature but it can surely make your experience better and faster. The touch screen in particular can be very helpful but the products that include this option are usually more expensive that those that don’t.
Trunk tracking
You will only need this feature if the individual (or organization) you want to listen to uses a trunked radio system. Without it, you won’t be able to tap in to that frequency.
Computer control
With this option, you can link your scanner to the computer in order to customize it.
Automatic mode and step selection
Your scanner will automatically choose the best mode and step for the frequency you’re trying to set so you don’t do this manually every time.
Alpha tags
You can benefit from this feature since it displays the identifiers related to the channels you’re searching for.
Dynamic memory
This system gives you the ability to edit the size of the banks or lists on your scanner so they wouldn’t take up additional memory space.
Doomsday Preppers and Radio scanners
If you watched the hit reality television series Doomsday Preppers (We know you did!) then you probably noticed that almost everyone has invested in a radio scanner. It goes without saying that this piece of equipment is really useful on a normal day but it becomes mandatory in the case of a large-scale disaster.
