What You Need To Know About Different Types of Radios


One of the first things you do when you get into your car is what? The radio is a popular way to find something to listen to if you’re like 244 million other Americans.

Although radio is widespread, many people are unaware of its capabilities. As we look back over the last century, what developments have been made in radios? In what ways do these tools facilitate communication and information sharing? You can learn how radios work by reading our guide. For more information, visit

The workings of radios

To understand how radio works, you must first have a basic understanding of how they work.

Transmitting and receiving electromagnetic waves at the speed of light is accomplished by radios. Although invisible to the human eye, these can carry speech and music information. A radio comes with a coded form, which varies depending on the model.

Radio types

The radio has evolved into many different forms since it was discovered in the late 19th century, each serving a different purpose. Listed below are six types of radios that are most important.

AM Radio

Known as AM radio, this is a form of wireless broadcasting that is one of the oldest. In AM radio, radio waves are altered by audio signals. Modulation is the term used to describe this process. After this modulation is received by your car or house radio, the AM radio decodes this sound into a discernible signal.

FM Radio

The majority of people who listen to FM radio in their cars listen to the station. FM radios were developed in the 1930s, and today they are a popular form of entertainment.

In FM radios, the modulation process alters radio waves, which is what makes them different from other radios. Contrary to AM, which relies instead on signal strength, this type of broadcast depends on the quality of the signal.

Due to all of these factors, FM offers better sound quality and less electrical interference in most cases.

Shortwave Radio

At around 1.7 to 30 MHz, shortwave radio has a frequency between 550 and 1720 kHz, while AM radio has a frequency between 550 and 1720 kHz.

An interaction between shortwave radio frequencies and the ionosphere takes place. There is no issue with shortwave radio broadcasts traveling hundreds or thousands of miles because of this. It is possible in some cases for people to listen to a broadcast from anywhere on Earth in some cases.

Shortwave radio is used by a wide range of users, including commercial stations and government agencies. A station like WWV, which broadcasts out of Fort Collins, Colorado, is an example of a station that is operated by the U.S. government. Listeners can receive time signals on 2.5, 5, 10, 15, and 20 MHz, and it broadcasts them in real time.

Satellite Radio

Radio broadcasting by satellite is a newer medium. A subscription is required, and it relies on satellites for power. By doing so, satellite radio is able to cover a large area without compromising the quality of the audio.

Radio stations on satellite are encrypted, which means you need a special receiver to listen to them. Listening to it is not enough just because you have the receiver. The receiver will not be able to access satellite radio channels unless you pay for the subscription plan.

Ham Radio

The Federal Communication Commission defines a set of frequencies for amateur radio, also known as ham radio. There are special equipment, licenses, and training requirements for using a ham radio.

The transmission range of ham radio is thousands of miles, just like shortwave radio. Many people find it to be a fun hobby because they can interact with people across the globe while improving their broadcasting skills simultaneously.
