Can A Scanner Pick Up Walkie Talkie Conversations

Uniden BCD436HP Police Scanner | 1st Power On & Set Up

Yes, some models can. These scanners will allow you to listen in on amateur radio frequencies, which can even include baby monitors, cell phones, and of course, walkie talkies. To learn more, read my guide on walkie talkie code, where youll also get some great information on the safest and best walkie talkies.

How To View Your Frequencies

There are some good frequencies to help program your UV-5R, which includes 146.520, and 446.000. These are simplex calling frequencies, which means they are monitored by local radio operators for simplex operation.

One conversation that starts on a simplex frequency is moved up and down to another through the frequency band when others call it. You will need a license to help transmit those frequencies. But in our tests, we found that simplex frequencies can receive and transmit better than MURS and FRS bands.

Hint: You will have to change your settings on your Baofeng to make 5K increments once youre programming frequencies. First press the menu button then find the item 1STEP. Then you can adjust it back to 5K.

These devices let you stay on top of local events and ahead of the curve in several potentially dangerous situations. You can also use a police scanner to stay abreast of local news before it’s reported on television, you can get weather alerts and find out about an impending natural disaster, or you can tune into amateur radio channels. The best police scanners can also serve as an alternative to a standalone CB radio or radar detector, so read on to see your options.

  • Hybrid CB radio and trunk-tracking scanner

  • Has GPS

  • Expensive

Although its one of the pricier options on this list, the Uniden Beartracker 885 is a full-featured CB radio and digital trunk tracking police scanner. It has GPS included, so it can automatically select nearby channels from its database . You dont have to do any sort of complex programming while you drive, as the scanner does the work for you. It provides weather alerts, PA functionality, and more, and you can easily read the LCD.

Getting Started With Your Scanner

Frequency lists are easy to obtain, often via the Internet. You can find a free frequency list for your area at this Web site.

If you buy a portable scanner, park near an airport sometime and search the VHF AM aviation-band range, from approximately 118 MHz to 135.975 MHz, to hear all the activity that is going on. In some areas, programming 123.45 MHz into your scanner will let you hear some pilot-to-pilot communications.

Many desktop models work on a 12-volt power supply, so a cigarette-lighter adapter will allow you to take one on a trip.

How Do You Listen To Encrypted Police Channels

How To

As we have covered above, that in order to have access to encrypted police channels, you will need to have a radio thats programmed with the encryption key.

The encryption key is necessary to decrypt the transmission and allow you to listen in.

If you are one of those radio enthusiasts this can be a bummer. With all that said, you can still listen into to the fire service, Utility departments, air crafts and towers which can be interesting as well

So you cant listen to police encrypted radio unless your radio can de-encrypt it.

Police Scanner Frequency Basics

Police scanners allow you to pick up radio frequencies & listen to communication on those frequencies much like an FM radio allows you to listen to different channels by changing the dial from 93.7FM to 102.5FM. By changing the channel, your radio is picking up one signal & blocking out another. Scanners operate the same way, however, the frequency you listen to & the scanner needed to use to pick up that frequency vary greatly based on where you live and what you want to listen to .

Radio frequencies in the US are defined & regulated by the FCC. Below is a visual representation of entire radio spectrum in the USA:

Overwhelming, right? Dont worry, you only need to know what ‘format’ is required in your area.

How To Use A Police Scanner

A police scanner or radio frequency scanner is a device that allows people to communicate in a specific area. The device can track waves in a given locality, just like a radio.

Radio scanners are commonly used for emergency services, although people now often use them just for fun or for in their car.

Using a police scanner is not complicated. The only somewhat difficult part is programming the device. This guide will tell you how to use a police scanner.

There are two main types of scanners the base model and its handheld alternative. Heres two examples of popular options of each type:

How To Find Your Local Frequencies

Your area has a unique set of numbers and you need to find what they are so you can put them in your scanner and hear them.

Think of frequencies this like an AM/FM radio:

  • Classic rock is on 98.1 FM
  • Sports talk is on 830 AM
  • Big difference.

    Scanners are the same, but there are innumerably more frequencies.

    Radio Reference. Your new scanning buddy!

    Radio Reference is the largest and free-est radio frequency database.

    It’s not perfect, but it’s a great tool for programming. We’ll show how this works.

    1. Navigate to Radio Reference

    2. Click this text field.

    3. Type in your zip code

    4. Click “Retrieve”

    5. Click on the link below your county name

    6. Simulcast distorted counties will have “Simulcast” in the name of the tower

    7. “DE” signifies encryption

    8. Upgrades will be indicated by name under “Mode” on the right-hand side

    Whats The Best Scanner Equipped With The Zip Code Scan Feature

    Uniden SDS100 Police Scanner Start-Up Guide | Tips & Tricks

    I recommend the Uniden Home Patrol- Simple Program Digital Scanner, which allows you to simply enter in your zip code and the device will automatically scan for local frequencies. This is a very beginner-friendly model that offers excellent range and clarity, easy setup, and plenty of other features that will help to keep you up to date with local events as they happen.

    Why Are Police Scanners Open To The Public

    As a Boston police manhunt took shape early this morning, Twitter feeds and Reddit threads were full of reporters and civilians tracking the events. Many people were using police scanners and apps that made Bostons police frequencies accessible on the web. For those who knew where to tune in, these frequencies provided incredible drama. A shootout took place in real time. Those listening to the scanners were able to hear it all unfold.

    Thats why scanners have been used for years by journalists and curious eavesdroppers: they put police actions in public. They allow any mildly savvy, curious person to listen in on the process of law enforcement as it happens. A 1997 article from the Society of Professional Journalists called police scanners about as necessary in a newsroom as is the pen and notebook.

    A police scanner can be “about as necessary in a newsroom as is the pen and notebook”

    But as police closed in on a second suspected terrorist on the run this morning, local police frequencies fell silent. The online feeds stopped. And a unified message went out: Boston area law enforcement feeds are temporarily offline to protect law enforcement resources and their efforts during the manhunt underway in the Boston Metro area.

    You may have wondered, as many on The Verges staff did: why are police scanners public in the first place? Why arent they encrypted to keep any Joe Blow on the web from listening in?

    According to John Banzhaf, theres no legal reason why.

    How Often Should I Change Channels

    Some cities and counties will always use the same channels and have for several years. As an example many police departments will use the same radio channels theyve been using for the past 20 to 30 years. In other places the frequencies change several times throughout the year.

    If you have a model thats equipped with the zip code scanning feature, I recommend updating its database at least once a month. On average channels are changed by emergency services twice a year.

    If you dont have a scanner with the zip code feature, then staying up-to-date with local frequencies can be incredibly difficult. Most models that dont come equipped with this feature will require you to manually search for local frequencies.

    Find Some Frequencies To Program

    There are many places where you can get frequencies for your radio scanner. Some of the frequencies may fail to get programmed into the scanner. These are likely to be frequencies of cell phones. Otherwise, they should be able to work with your scanner perfectly.

    Shops that sell police scanners usually have a list of frequencies available. For hobbyists groups, you can usually find the frequencies on the internet. You just need to google the hobbyist group name or find them on Facebook.

    You can also find frequencies on If you are on the website you can go to the frequency database at the top bar of the page. Under this, you should click on the frequency database, at which point you will get a map of the United States.

    Find your state on the map and click it. It will be magnified, and then you can find your county. At the bottom of the screen will be a list of the various frequencies in the state, alongside their category. It is also wise to see if it is legal to use a police scanner in your state before you begin.

    The website mainly lists official and important frequencies, so you shouldnt expect to find frequencies of local hobbyist groups.

    If you are using a handheld device, you can scan the locality for available frequencies. This is done by pressing the scan button.

    Programming A Base Police Scanner

    Step 1: Find the frequencies you want.

    Police scanners are all about frequencies, so the first thing you needto do is find which ones you want to listen to. There are lots of sourcesonline that can provide you with a database of frequencies in your area.Whether you want to listen to nationwide, statewide, or county systems, you can select a wider or a more specific coverage.

    Mind you, this is the manual way of doing it. Its great if you want tolisten to specific channels only and you dont want a lot of clutter in yourmemory. So, collect the frequency reference numbers you want and be prepared to input them in your base model.

    Step 2: Power Up the Police Scanner

    With frequency list in hand, turn on your police scanner to start. Ofcourse, once the scanner is on, you wont hear anything yet because nothings programmed.

    Step 3: Press the programming button.

    Its usually on the face of the base model along with the other buttons. It can display Prog or PGM depending on the police scanner model. Press it to activate programming mode. Watch out for the CH letters on the screen, indicating youre ready to input a channel and frequency.

    Step 4: Input the channel number.

    This is where you store your frequencies. There are all sorts of ways you can organize them into channels, but the most common way is to assign one channel for fire, another for emergency services, another for police, and so on.

    Step 5: Input the frequency number.

    Step 6: Press enter.

    To Encrypt Or Not To Encrypt Is The Question

    Before encryption, media companies used to listen in on the radio for situations that may arise and which may need their attention.

    Media companies used to assign a person to listen in and if a good situation arises, they can cover it.

    Radio enthusiasts also listen in on the channels, some enthusiast even helped the cops solve crimes by providing infos to them, but all these came to an end when encryption came.

    Note : I Just Installed A Fresh Version Of Op25 On A Raspberry Pi 4 And There Was No Cmake Error Gnuplot Is Built In Too Now It Looks Like

    GMC SUV Police Scanner Installation by Monney Redwood City ...

    git clone

    It will make a folder called op25

    cd op25

    Wait a bit for it to install. It should take care of everything.

    Now it is installed but there are three obstacles to overcome.

    • How to launch the program with what command to use
    • How to set up the file trunk.tsv
    • How to set up the file yourcity.tsv

    Thats basically it. Now my assumption here is that you are using a generic RTL-SDR device. Im using a V3.

    These will set you back about $30 or so. But you only need one of these to track a trunked radio system.

    So plug in your RTL-SDR device and lets get ready to do this thing.

    Im going to demonstrate using my home town of New Bern NC. Lets find the trunked system to follow.

    Go to this page to list the frequencies.

    This page will not always be spot on. The actual control channel at the moment is 857.2625.

    To find the control channel if you dont know which one it is just open a program like GQRX and look and listen for the control channel. It will sound like digital noise. And the signal will be a constant spike. As you can see I found my Control Channel at 857.2625 as stated above.

    Now go back to your system and get in the correct directory. Check your path for accuracy.

    cd /home/john/op25/op25/gr-op25_repeater/apps
