Does Best Buy sell police scanners?
Best Buy does sell police scanners with many brands available like Uniden, Whistler, Midland, Cobra, and the in-house and affordable Insignia brand. You can find options ranging from handheld to bigger base and truck-mounted scanners.

What is the best handheld police scanner?
For a handheld scanner, we're partial to the Uniden Bearcat BC75XLT. It's a handheld scanner that can connect to public safety, military aircraft, and racing scanner channels. It's an analog scanner that can quickly identify police, fire, marine, air, weather, and more. The scanner can handle 300 channels in its memory, or 30 channels in 10 separate banks. It only requires two AA batteries to work, making it a good portable option to take with you on the go.

What is the best digital police scanner?
Our top pick for digital police scanners is the Uniden BCD996P2. It comes from a well-known brand with support for both analog scanning and digital transmissions. It can also do location-based scanning and detect nearby transmissions. The scanner supports continuous band coverage from 25MHz to 1.3GHz, with 25,000 dynamically allocated channels. If you want to cover all your bases, it's a great option.

What to Look For in a Police Scanner


Police scanners are available as handheld units, as mobile scanners you install in a vehicle, or as desktop scanners that aren’t portable at all. If you only want to use your police scanner in one location, a desktop scanner or mobile scanner will suit you fine. If you want to have more options, go for a handheld police scanner. 

Analog vs. Digital

Your ability to listen in on transmissions from your local police and other agencies hinges on compatibility between their transmitters and your scanner. Digital scanners tend to have the best compatibility, but you’ll get by fine with a less expensive analog police scanner if your local agencies haven’t made the jump to digital yet.

"Using analog or digital would depend on the area you live in. Some provinces and countries are switching to digital, so you would need that depending on where you live." — Whitney Joy Smith, President of Smith Investigation Agency

The other feature that can impact your ability to receive transmissions on a police scanner is trunking. Scanners that don’t support trunking cannot tune in to trunked systems, so this feature is a must-have if your local agencies use trunk lines. is an excellent resource for finding out if you can receive analog signals in your area.

Additional Features

Do you want a basic scanner or a police scanner with extra bells and whistles? Some scanners may have extra features like an alarm clock, GPS, Wi-Fi, or CB radio functionality. 

"The newer police scanners have a built-in GPS to automatically change to different channels as you travel from area to area. This is important as users can filter through channels to get signals nearby or in a specific location elsewhere." Whitney Joy Smith, President of Smith Investigation Agency



Uniden Bearcat Police Scanners have been considered the BEST scanner brand in the world! 

Scanners are an excellent way to stay informed of local activities and are utilized for both personal and professional use. They scan or check many channels/frequencies of various two-way radio communications, including police, fire, and others. 

  • Police
  • Fire
  • Air Traffic
  • Railroad
  • EMS/Rescue
  • And much more!

Selecting a Scanner

Here are some important considerations to have when selecting a scanner:

  • Do you want a desktop scanner, handheld/portable scanner, or a scanner that you can use in your vehicle?
  • Do you need an analog scanner or a digital scanner?
  • What features are you wanting for your scanner?

Analog Versus Digital

When shopping for a police scanner, it is important to know if your local police/fire and other emergency providers are still on analog or if they have switched to digital communications.  This is very important!  If they have switched to digital, an analog scanner will not pick up those communications.  A digital scanner will pick up both analog and digital communications.  

On, you will find a great selection of Uniden/Bearcat analog police scanners, digital police scanners, & handheld and base station police scanners.  If you have any questions or need help with product selection, please contact us!

APCO Project 25

APCO Project 25 (P25) Trunked Radio Systems (TRSs) because they follow the open APCO's Project 25 Standard for Public Safety TRSs. Multiple vendors make and sell Project 25 systems and compliant radios. Audio on these systems is exclusively digital using the APCO-25 Common Air Interface (P25 CAI) standard.

There are several "Subsystem" features defined as part of the Project 25 Standard to enhance interconnectivity & interoperability and allow equipment from various manufacturers to work together.

These standards include
  • P25 Common Air Interface (P25 CAI)
    • Over-the-air modulation (digital audio)
  • P25 Inter-RF Subsystem Interface (ISSI)
    • The Inter-RF Subsystem Interface (ISSI) standard allows P25 systems from different manufacturers to be directly interconnected at the controller level, allowing seamless cross-system intercommunication, and system-to-system roaming for same-band systems.
  • P25 Console Subsystem Interface (CSSI)
    • The Console Subsystem Interface (CSSI) allows dispatch consoles from different manufacturers to be connected to the controller/core of other manufacturers' systems. For example, a Zetron console could be connected to a Motorola system, or a Harris console could be connected to a Tait system.

Project 25 uses either IMBE vocoder. IMBE stands for Improved Multi-Band Excitation or AMBE Advanced Multi-Band Excitation, and both were developed & licences by DVSI Inc. Numerous vendors have produced Project 25 capable subscriber equipment, including EF Johnson, Motorola, M/A COM, Racal, Uniden, and others. There are Conventional and or Digital Trunk solutions, both available to use P25 Digital Voice via compatible transmitter, transceiver and/or receivers.

  • Currently, Motorola's implementation of P25 digital data & voice is marketed as "ASTRO-25", for both older Motorola Type II and Phase I systems for two of their types of trunking solution, they utilize the P25 IMBE vocoder, with their newer AMBE or AMBE2 radios are backwards compatible with systems that use the IMBE packaging.


This is a P25 non-compliant Motorola digital solution, and is also called the "ASTRO Digital CAI (Common Air Interface) Option".This is a proprietary trunking solution that uses the Project-25 vocoder as its digital voice solution on top of a standard Motorola Type II Smartnet/Smartzone system.

Project 25 Digital Trunking

This is the Project 25 (P25) Digital voice & data trunking solution, is one that is vendor independent and designed around the Project 25 Digital Trunking standards. Phase I(PI) is 4800 symbols per second - where each symbol encodes two bits of data for a raw bit rate of 9600 bps. Phase II(PII) is 6000 symbols per second where each symbol encodes two bits of data for a raw bit rate of 12000 bps and utilizes the AMBE vocoder.

Project 25 Phases

Project 25 Phase I "FDMA"

Phase I FDMA consists of C4FM modulated signal or a CQPSK modulated signal. Both fit in a 12.5 kHz channel. Subscriber equipment transmit in C4FM. Site equipment may transmit in C4FM or CQPSK. Simulcast uses CQPSK modulation, however older Motorola ASTRO equipment used C4FM simulcast in a special mode called "WIDE pulse" which is not P25 compliant. P25 CQPSK Linear Simulcast Modulation is P25 compliant and is referred to as LSM. LSM is defined in the P25 standards.

Motorola "X2-TDMA"

Prior to the final Phase II standard being approved, Motorola developed and implemented their own TDMA protocol known as "X2-TDMA" uses the same modulation as Phase 1. X2-TDMA was implemented on the following systems which may have been upgraded to Phase II since the standard was finalized in late 2013. Search the database for others:

Project 25 Phase II "TDMA"

The Phase II standard is a 2-slot TDMA signal that fits inside a 12.5 kHz wide channel, providing a two 6.25 kHz-equivalent channels. Fixed site output modulation is H-DQPSK with subscriber units using H-CPM on the input. This allows existing 12.5 kHz wide license holders to double call capacity by upgrading their infrastructure to Phase II. The Phase II standard was Finalized and Approved in November 2010 [1], and Motorola has began shipping Phase II systems as of August 2011 [2][3].

Motorola ASTRO-25 Phase II systems can also have an optional feature known as Dynamic-Dual-Mode (DDM), which will seamlessly revert a whole talkgroup (TGRP) to FDMA operating mode if a Phase I-only radio affiliates with a Phase II TDMA TGRP, and only go back to TDMA once all Phase I-only are unaffiliated with said TGRP.

Scanner Support FDMA and TDMA

Scanner Support for FDMA

The following scanners can only decode P25 Phase I, but not Phase II


1 Does not cover or will not properly track the 700 MHz band.

Scanner Support for TDMA

The following scanners can decode P25 Phase I, Phase II, and Motorola X2-TDMA systems.


2 Requires latest firmware update.
3 Requires Whistler Official Upgrade (WOU).

Project 25 Receivers

Software Based Decoders

See our Trunked Radio Decoders page for a listing of applications. Packages like Digital Speech Decoder, DSDPlus, can handle Phase 1 signals. SDRTrunk can handle Phase 1, Phase 2, and DMR, and DSDPlus also handles X2. In addition there are various decoding applications such as UniTrunker and Pro96Com.

Some like DSDPlus may also be used by Software Defined Radio (SDR) such as the RTL-SDR.

Using a PC running Linux' Ubuntu, it is possible to compile/build and run the software package OP25 to monitor Conventional and/or Trunked P25 Phase I & II systems. OP25 only requires one SDR device, whether it be an RTL-based or something more capable like a HackRF or Airspy. At the current time (Jan 18) OP25 only builds out and works properly using Ubuntu 14.04.x LTS; the current version is 14.04.5 and it is a Long Term Support (LTS) version, so there will be updates through at least April 2019.

In November 2019, OP25 was successfully built and run on a Raspberry Pi 3 under Raspbian Buster. Therefore, there is now an alternative to Intel based architecture under Ubuntu.

A cross-platform application called SDRTrunk written in Java can handle P25 Phase I, II and DMR with the latest build. It supports tuners such as Airspy, Funcube Dongle Pro, Funcube Dongle Plus, HackRF, RTL-2832 with Elonics E400, RTL-2832 with Rafael R820T or R820T2, and sound card(s) connected to scanner audio output.

Desktop Receiver Support

NOTE: No trunking support with these radio. Phase I only.

Project 25 Trivia

Conventional P25 systems don't support CTCSS tone or DCS code for access. Instead they use what is called a NAC. This is a 12 bit code that prefixes every packet of data sent (including voice packets).

For trunking, the control channel delivers an average of 40 trunking commands per second. These commands may carry caller or callee identifying information such as a radio id or talkgroup. Talkgroups are 16 bits - allowing over 65000 talkgroups. Radio ids are 24 bits - allowing over 16 million unique radios. To support roaming, radios are associated with two additional IDs - a system ID and a WACN. The system ID is 12 bits while the WACN is 20 bits - allowing for over 4 billion unique systems. Voice channels are identified in trunking commands by a 16 bit number. These 16 bits can be broken down into two pieces - a four bit identifier and a 12 bit channel number. The 4 bit identifier selects the appropriate bandplan. A bandplan is a simple algebraic formula for computing a frequency from a channel number.

Some P25 trunked systems, including many military 380 MHz systems, have WACNs that decode into a hint as to the system's name. The encoding of WACNs in these cases follows the "Guidelines to Assign Wide Area Communication Network and System Identities" document approved by the APCO Project 25 Steering Committee on April 6, 2001. For example, WACN 580A0 decodes to "NCR" (National Capital Region). A conversion application is available to decode WACNs and System IDs. The real intent of this encoding scheme is to generate unique WACNs and System IDs from a trunked system's license callsign.

Ways To Listen

I have gotten the police scanner bug again.  There are a lot of reasons to have a radio scanner (the proper term for police scanner) with the best reason being informed during emergencies.  Other reasons could include being aware of your surroundings, listening to news as it happens directly from the source, having knowledge of criminal activity in your area, or just plain old being a radio geek who likes to listen to stuff.

There are a few ways to listen.

  • Having a dedicated hardware radio scanner
  • Streaming from the internet on systems such as Broadcastify.  While these are handy and free you are going to hear one system at a time. In my case if I listen to my city system, I will completely miss the statewide system, the sheriff’s system, and all analog broadcasts.  You can listen to just one thing at a time.
  • Streaming from smartphone apps (which mostly tie into Broadcastify). You should note that the internet streaming and apps generally are about 30 seconds to a minute or two behind real time.  Bad boys, bad boys could be busting down your door before you hear it on the iPhone app.
  • Creating a software radio using an RTL-SDR USB radio device and software designed for digital trunking radio.

Also we should know what is available in the area that we live in prior to selecting a method of listening.    There are a lot of things to listen to and not every scanner is created equal.  There are two principal types of signals:

  1. Analog – generally parked on one frequency.  Think two walkie talkies set to the same channel.   Also think CB radio.  Everybody on channel 19 could talk to everyone else on channel 19 provided they were within range.
  2. Digital –  Digital systems are much more complex and can be Trunked systems which use multiple frequencies and use a control channel which permits the simultaneous use of those assigned frequencies.  MOST CITIES THESE DAYS HAVE DIGITAL TRUNKED RADIO SYSTEMS although in many small towns they may still use analog systems.

To complicate the digital thing a bit more there are different systems which are common for cities or municipalities to use. The most common are DMR, P25 Phase 1, P25 Phase 2, Motorola EDACS, and NXDN.  Some scanners are ONLY ANALOG, and some scanners may be digital but only capable of P25 Phase 1.  If your city uses P25 Phase 2……….THAT SCANNER WON’T WORK.

Some cities may use encrypted digital transmissions.  If that is the case you may as well not even buy a scanner because you can’t listen.

Many areas will have a combination of both analog and digital trunking systems.  Wow!  This is getting ridiculous, huh?

The first things you want to know is “what is available in my area?” and “what am I interesting in hearing and equally as important what am I interested in NOT hearing?”  Let me explain what I mean by “NOT” hearing certain things.   Some higher end scanners seemingly do it all. Analog, digital, and with all the digital systems as well.  Also to make it easier on you when you boot the device it asks you for your zip code and it dips into its (user updatable) database and PULLS IN EVERYTHING AVAILABLE IN YOUR AREA.   That is mega-cool, it really is but I bet your area has HUNDREDS UPON HUNDREDS of channels, with several digital systems.

You may want to listen to just the police but you’ll find yourself listening to the desk clerk at the hotel near you calling the maintenance man to check on a leaky faucet.   When I stay at hotels many times they are near the airport and I hear the baggage handlers, the shuttle bus drivers, the restaurant employees, the mall security folks………….you get the idea.  While your scanner is scanning all this stuff you are missing the calls that you may want to hear.  And of course some scanners have Priority Modes where you can set your favorite things to high priorities.   All very cool and all very complicated.  If you aren’t a super geek ready to dive in deep it could be VERY FRUSTRATING.

So, lets see what is out there.  There are a couple good resources to let you know what is available.  First is  Go to the Database tab at the top of the page and select your listening area by clicking on “Frequency Database”.

Radio Database tab

Click on your state and then your county and it will list analog channels and digital systems.   Here is just a partial snip of what is available where I live.   Note that the ones that show the first field of “Frequencies” are Analog and under the Trunked Systems on the right of each system it shows what kind of system it is.

RadioReference database results

If I wanted to listen to EVERYTHING here I would need a scanner that does Analog, Digital P25 Phase 1 and 2, DMR, and Motorola Type II.   Now let’s get realistic for a moment.  I could give a crap about Progress Energy.  Also the Marine Bases probably use encrypted radios.  The DMR stuff is ham radio repeater things and I have a DMR ham radio system already.  Realistically, all I  care about here is North Carolina VIPER and New Bern Public Safety which are both P25 Phase 1 systems.

That narrows things down quite a bit.  If that is all I care about I can get a scanner that does P25 Phase 1 and call it a day.  You can save quite a few dollars by narrowing it down somewhat like this.

BUT WAIT!  There’s more!  Radio Reference doesn’t capture it all. Try this web page; Digital Frequency Search.  For example let me pull down an NXDN system example where I live.   There are 59 NXDN channels which include Fairfield Harbour (not where I live), Norfolk Southern Railroad, and Craven County Schools.

NXDN Search Results

None of those things interest me at all, however I guess if there were a rail accident/incident it might be interesting to listen to.  I could create a Favorites list and just not enable it and turn it on when I thought it might be interesting.

Your mileage could vary here.  Your NXDN system could be your police or something that really interests you.  In that case you need a scanner that does NXDN.  Some scanners make you PAY EXTRA to turn on NXDN support.  Yikes!

So in my case I’m still back to where I was a minute ago.  I have two P25 Phase 1 systems which interest me.  The cheapest route for me to go is by making a software defined radio.  In this case I need a Raspberry Pi (or laptop with Linux on it) and an RTL-SDR device which costs maybe $25 or so.  I have captured the process for making a software scanner on this web page.  This is BY FAR THE CHEAPEST WAY TO LISTEN TO P25 PHASE 1 AND 2.

Okay, what are the limitations here?  Digital only.  No analog.   There are some interesting analog channels around me and very small towns and townships that use analog still.  The city I live in has quite a bit of analog stuff.

Here’s another consideration.  Are you on the move?  Do you run up and down the road?  Some Scanners will allow you to attach a GPS module which will adjust as you travel from location to location.   Those modules are usually pretty expensive.  I have a website that shows you how to DIY one for much less money. 

As I mentioned before I travel a lot and when I’m in the hotel I always enjoyed having a scanner on for background noise.  I’ve heard plenty of interesting stuff.

What I haven’t mentioned yet are specific scanners and I guess it is time to get into that. First and foremost is that a digital scanner that does P25 Phase 1 is going to be upwards of $250, maybe even used.  Anything that does P25 Phase II is going to cost more than that.  Seems like the decent offerings are in the high $300 range.  Top of the line digital scanners are going to cost upwards of $600.  In a scenario where you only wanted to listen to one digital trunked system, you might want to look into making your own scanner with a Raspberry Pi and RTL-SDR as I discussed earlier.   You can do it for a FRACTION OF THE COST.  It all depends on what you want to listen to.

Here is my opinion of the best scanner in the land, bar none.


Uniden SDS100   – It ain’t cheap though, let me tell you.  Right now it runs about $650 and DMR and NXDN capability costs extra.  Yikes.  You’re talking real dough here.  But it does it all. And with some 3rd party software like ProScan it adds capabilities that Uniden itself doesn’t give you, like the ability to stream your scanner feed to a webpage and to record.   You can program it by zip code and you can easily make a favorites list and turn on and turn off systems you don’t want to hear.   Arguably, this is the best scanner in the world.  The other exception to that might be its brother, the Uniden SDS200 which is the same scanner essentially in a desktop version.


Whistler Scanners – I’m not a fan of Whistler scanners. I have a TRX-1  and it struggles with the New Bern Public Safety P25 system.  Remember when I talked about P25 Phase 1 and Phase 2?  Well guess what?  In P25 Phase 1 there are two types of simulcast modulation.  C4FM and LSM.  The TRX-1 is NOT GOOD AT LSM.  It is a well known limitation.  Guess what New Bern Public Safety is?  Yep.  It drops, has lots of digital hash and crap and just isn’t reliable.  Don’t get me wrong though.  The TRX-1 is an INCREDIBLE SCANNER…….just not on LSM systems.  If you live in an area that doesn’t have P25 Phase 1 LSM……….by golly a TRX-1 is your Huckleberry.   Also it is cheaper than a Uniden SDS 100 and NXDN and DMR modes are FREEEEEEEEEEEEEE.  Free Baby, yeah!

Uniden Homepatrol 2 – This might be a close runner up to the SDS 100.  This has a touch screen interface, is probably a lot more user friendly than either of the two listed above, and it can be used as a desktop scanner or as a handheld.   It is ridiculously feature rich but in a very easy and more intuitive fashion than the other mentioned scanners.   Basically the “2” stands for P25 Phase 2.  If you don’t have a Phase 2 system you can get the Homepatrol 1 for considerably cheaper.  The “1”, you guessed it, is for P25 Phase 1.  Uniden doesn’t show them as being for sale anymore but you can still find them on eBay.   Neither the 1 or the 2 does DMR or NXDN so again, you gotta know what you want to listen to.  The downside here is that it doesn’t come with an AC adapter.  #YOUGOTTABEKIDDINGME.  But you can add a GPS module to it which is really cool.

Uniden Homepatrol 2 radio scanner

Uniden Bearcat BC355N – This could be a tempting choice because it only costs $100.  The downside here is that it is ANALOG ONLY.  Don’t get fooled by the low price tag.  If you live in a town that is analog only this would work just fine.  Also you could buy one of these as a secondary device to only scan analog channels and free up the expensive device to only listen to Trunked Radio which of course would speed up the scan time.   You’d have to be kind of ate up to have two scanners running all the time.   Also you can do the same thing with an RTL-SDR device and free software such as SDR#.  In short, beware the low price unless you know exactly what you are getting and it fits your needs.

There is an old ham radio adage that roughly states:  “For every dollar you spend on a radio, spend 2 on the antenna”.  Your overall experience will be better with a good outdoor antenna.  I took an old phone booster antenna that is tuned to 800-1000MHz (approximately) and attached it outside.  Even though some police VHF analog transmissions are around 150MHz and technically out of the frequency range of the antenna my analog reception has improved wildly. Heck, anything is better than the rubber duck and having 15′ of coax connected probably acts like a VHF antenna anyway somewhat.

Everything I have mentioned (except making your own scanner) is relatively expensive.  There are some cheaper trunking scanners out there but I recommend this…………Don’t just buy one off of the internet.  Search out scanner users in your area or ask questions on the Forums at about limitations.  Just because someone says it is great on the internet doesn’t mean it is what you need WHERE YOU PLAN TO USE IT.  On paper it may say it works such as my Whistler TRX-1 and then $500 later when you get it home…………….Crap.  It doesn’t work on the system where you live as per my example of the TRX-1 not working on P25 Phase 1 LSM modulation.

In regards to purchasing a scanner……………..there is some homework involved.  Now more than ever in the times of COVID and rampant bad news such as impromptu riots and demonstrations it may never be more important to listen to your local police, fire, and EMS transmissions than it is right now.

Last point:  A scanner that works great where you live might be nearly useless 40 miles away in a city that uses a different system.  DO YOUR HOMEWORK.
