Beginners Guide to Buying Radio Scanners

Radio scanning is a hobby that has been around since the 1970s. The first radio scanners were not as nice as the ones found on the market today, but they did allow citizens to find out what was going on in the community.

During this time, CB radios were a popular way to communicate, so anyone who owned a radio scanner could tune the radio channel to the same frequency to hear the conversations that the truckers were having. Listening in could be a great way to get information about accidents and road conditions ahead on the highway.

These devices used to only have a few channels to tune into. The reception was bad and the audio was sluggish, but it was a way to be informed. Today, radio scanners are designed with much more advanced technology, so the device is much higher quality overall.

What Are They?

A radio scanner is a device that is designed to surf the radio frequencies in the air to find ones that have activity on them. Once the activity is located, it is easy to listen in on the conversations being held by others. It is a way of eavesdropping that does not have the consequences, as long as it is used according to the rules and regulations of the state that it is being used in.

There are two different types of radio scanners popular on the market today. The first is the handheld variation that is designed for portable use. Typically, this type of scanner is designed to be on the person of the individual using the device, which means that they run on battery power.

There are also scanners that are designed with a base that secures the device in a specific location. In most situations, these types of radio scanners are placed in a vehicle, but some individuals prefer to keep them inside their home.

Scanner models will also have a method that they use to transmit the signal. Almost all of the older models transmit the traditional AM and FM radio signal, but some of the newer radio scanners no longer have this function. The most common method used today is still analog, but digital transmitting is making a footprint in the sand as well, but that technology is not advanced enough yet.

Who Are They For?

There are many uses for a radio scanner. They can be used for professional means or they can simply be a hobby that an individual takes an interest in. Radio scanners are used by those who are interested in law enforcement. Some people enjoy listening to conversations that the investigators are having about an ongoing investigation. Emergency warnings will also often be broadcasted over radio scanners.

Anyone who is interested in the military activity occurring in a specific area of the world will be able to hear the communication between the commanding officers and their company. It can actually be a pretty exciting experience to hear some of the Intel of a military operation.

Any writer who likes to keep up with all of the current events will also find that having a radio scanner can be useful for getting the story first. It will help a reporter know when and where news is occurring, which will help them get the scoop and the headlines.

Weather watchers will also want to have this device. It will help them know exactly where bad weather is going to hit so that they can get a great image of the perfect storm. Most weather watchers like to capture tornadoes, hurricanes, flash floods, or blizzards. If it is a dangerous situation to be in, then they will want to know about it before it occurs, and the best way to locate these storms is to hear the details straight from the meteorologist.

What to Look for in a Good Radio Scanner?

As with any new purchase, there are a few features to consider when purchasing a radio scanner. Each one is important to get the best performance out of the device, but they may not all be needed, depending what the device will be used for. Here are some of the considerations that are the most important for a purchase:

  • Frequency – This is the most important feature of a radio scanner. The frequency will be the key factor in determining the radio signals that the device will pick up. Having a large range frequency is always best so that more signals can be heard. Typically, a range from 25 MHZ, which will broadcast CB radio signals, to a frequency of 800 MHz, which is used for aircraft transmissions.
  • Memory – As with anything, the more memory a radio scanner has, the more useful it can be. Memory allows the frequencies to be stored for quick access; meaning that all of the most listened to frequencies can be accessed without much effort.
  • Power Requirements – All portable scanners require batteries to run, but the question is which type of battery power does each one use? Some of the older models utilize a large battery pack that can be costly to replace, while others simply use AA or AAA batteries to function. These batteries can often be recharged, so it will cost less money in the long run.
  • Functionality – How easy is the device to control? Are there a lot of buttons that can be confusing to navigate or is it a simple interface that is easy to use? Make sure that the display is easy to read in any lighting as well. The antenna is also an important aspect of any scanner because the better the antenna, the better the reception of the frequencies will be.

Are They Worth the Money?

A radio scanner has a lot of uses, but purchasing one can also be a costly experience. The radio scanners featured on this list range in price from around $100 to nearly $500, and some of the scanners on the market can even be more expensive than that.

So, is it worth the money? Well, most hobbyists would say that it is a valuable investment to make. Most scanners have a durable construction that will ensure that they can be used for years.

If a portable radio scanner is purchased, it can be a companion while driving down the road. Even scanners that have a designated base can be installed in a vehicle to be listened to on long road trips. Knowing that there is an accident ahead that will cost hours of valuable time is well worth the cost. With that information alone, the accident can be avoided, and the travel destination can still be reached in time.

Wrapping Up

Having a police scanner can provide you with a sense of safety that many other pieces of technology cannot. These products pick up the occurrences of fire and police emergencies in the immediate area and can even provide information like the weather and the racecar driver chatter.

The best radio scanners for each user will vary by preference, but the products that have been covered in this guide can all provide excellent functionality for any degree of police scanner enthusiast.
