Scanner Radios - Peak Listening

Scanner radio listening is one of the most intriguing and engaging aspects of the communications hobby and an extremely powerful tool for the prepper. Whether you're an enthusiast or a beginner, having the right police scanner can open up a whole new world of real-time information and entertainment. In this post, we'll explore everything you need to know about police scanners, from their functionality to selecting the best one for your needs.

What Are Scanners?

A scanner is a radio receiver that monitors ("scans") multiple channels quickly, allowing you to listen to two-way radio calls. These radios, used by police, fire departments, and other services, transmit short bursts of information on thousands of channels. Scanners make it possible to keep track of these transmissions, offering a window into the activities of local authorities and emergency services.

Types of Scanners

Handheld Scanners

Handheld scanners are portable devices that allow you to monitor frequencies on the go. They're ideal for those who want the flexibility to listen from different locations. Popular models often come with rechargeable batteries, built-in antennas, and user-friendly interfaces.

Base/Mobile Scanners

Base or mobile scanners are larger units designed for use in a fixed location or mounted in a vehicle. They typically offer greater range and more features compared to handheld models. These scanners are perfect for enthusiasts who want a robust setup at home or in their car.

Digital Scanners

Digital scanners are capable of decoding digital signals, which are becoming increasingly common in public safety communications. These devices are essential if you want to listen to agencies that use digital encryption.

Trunking Scanners

Trunking scanners are designed to follow conversations across multiple frequencies, which is essential for listening to modern, complex radio systems used by many public safety agencies. This technology ensures you don’t miss any part of a conversation.

Why Use a Police Scanner?

Stay Informed

One of the primary benefits of a police scanner is staying informed about what's happening in your community. Whether it's a major accident, a natural disaster, or a public safety alert, you can get real-time updates directly from the source.

Enhance Your Hobby

For radio enthusiasts, police scanners add a new dimension to the hobby. The thrill of hearing live communications and understanding the nuances of radio technology can be incredibly rewarding.

Emergency Preparedness

In emergencies, having a police scanner can be invaluable. It provides immediate access to information that can help you make informed decisions and stay safe.

How to Choose the Right Scanner

Determine Your Needs

The first step in choosing a scanner is determining what you want to listen to. Are you interested in local police and fire departments, or do you want to explore a broader range of frequencies? Knowing your interests will help narrow down your options.

Consider Your Location

Your location plays a crucial role in selecting a scanner. Urban areas often have more complex radio systems, which may require a trunking or digital scanner. In contrast, rural areas might be adequately covered by a basic analog model.

Set a Budget

Scanners come in a wide range of prices, from affordable basic models to advanced units with numerous features. Setting a budget helps you focus on options that meet your financial constraints without compromising essential functionalities.

Consult Experts

When in doubt, consult the experts at Scanner Master. Their knowledgeable staff can guide you through the selection process, ensuring you find the perfect scanner for your needs.

Getting Started with Your Scanner

Basic Setup

Once you have your scanner, the first step is to set it up. Most scanners come with a detailed user manual that guides you through the initial setup process. Start by entering the frequencies for your local agencies.


Programming your scanner involves entering the frequencies of the channels you want to monitor. Many scanners allow you to program multiple channels, creating a comprehensive listening experience.

Using Preloaded Databases

Some advanced scanners come with preloaded databases, making it easier to find and program frequencies. These databases are regularly updated, ensuring you always have access to the latest information.

Advanced Features to Explore

Signal Stalker/Close Call

This feature allows your scanner to detect nearby transmissions automatically. It's particularly useful for discovering new frequencies in your area.

Trunk Tracking

As mentioned earlier, trunk tracking is essential for following conversations on trunked radio systems. This feature ensures you don't miss any part of a communication stream.

Digital Decoding

If you have a digital scanner, explore its digital decoding capabilities. This enables you to listen to modern digital trunking communications used by many public safety agencies.

Tips for Optimal Listening

Use an External Antenna

An external antenna can significantly improve your scanner's reception, especially if you're in an area with weak signals. Investing in a quality antenna can make a noticeable difference in your listening experience.

Stay Updated

Radio frequencies and systems can change over time. Regularly updating your scanner's programming ensures you always have access to the latest channels.

Join a Community

Joining a community of scanner enthusiasts can enhance your experience. Online forums and local Ham Radio clubs offer a wealth of knowledge and can help you stay informed about the latest developments in the hobby.

Legal Considerations

Know the Laws

It's important to be aware of the legal considerations surrounding scanner use. Laws vary by location, so make sure you understand the regulations in your area.

Responsible Use

Always use your scanner responsibly. Avoid interfering with emergency communications and respect the privacy of others.

Troubleshooting Common Issues

Poor Reception

If you're experiencing poor reception, check your antenna connection and consider upgrading to an external antenna. Location matters, so try different spots in your home or vehicle.

Difficulty Programming

If you find programming your scanner challenging, refer to the user manual or seek help from online resources and forums. Many scanners also offer customer support for troubleshooting.


Interference can be caused by various factors, including electronic devices and other radio signals. Identifying the source of interference can help you mitigate its effects.


Police scanners are a fascinating and valuable tool for staying informed, enhancing your radio hobby, and preparing for emergencies.
