Though we may not pay much attention to what it is, we’ve all listened to AM radio at some point in our lives. Whether it be to catch up on the latest news in our area, listen to music, or listening to an AM talk show, we’ve all heard AM radio without really taking a moment to truly understand what it is, how it works, and everything in between.

What is AM Radio?

AM radio, Amplitude Modulation, is a broadcasting radio signal that transmits information through the form of multiple electromagnetic waves. The carrier frequencies are within a range of frequency that reaches between 535 to 1605 kHz and assigned to a 10 kHz interval. To make it sound easier, this is the another option when you are not listening to an FM.

When compared to FM radio, AM radio has a lesser deal when it comes to overall sound quality, but the transmissions can go a lot further and are a cheaper aspect to radio. The bandwidth is also a lot lower, but this is actually a good thing because more radio stations become available through any range of frequency.

How Does AM Radio Work?

AM radio works through the Heterodyne principle, which is a method that transfers a single broadcast signal from the carrier to a local, fixed intermediate frequency through the receiver. This is done so that the majority of the receiver will not have to come back once the channel is changed.

The interference of two waves produces what is known as a beat frequency for the purpose of tuning the radio in order to apply a force that will further produce a beat frequency, one that is specifically an intermediate frequency, or an IF. Heterodyne principles are used within a receiver for AM radio and play a large part in ensuring it’s practical for a mass communication wave.

An electromagnetic carrier wave carries the signal through frequency modulation or amplitude modulation and transfers the signal itself to the carrier through multiple frequencies as a result from heterodyning. This is accomplished through mixing a sine wave and a modulated carrier. This, in turn, produces a beat frequency that is equal to the frequency’s differences and constitutes an additional carrier for modulating the original signal.

When it comes to radio transmission, this is crucial for the development of the heterodyning schemes, which actually led to the mass communication that was brought on by AM and FM radio. Fixing the beat frequency through the local and incoming carriers to an IF has helped to construct the majority of radio receivers in order to use incoming signals.

Once the input amplifier has been properly tuned for the purpose of a station’s carrier frequency, a local oscillator is in turn tuned as well to produce the proper beat frequency that is equal to an IF.

If the Heterodyne principle did not exist, we would not have as much access as we do through AM radio. Whether you realize it or not, we all take advantage of the fact that one single radio receiver is able to be tuned for the purpose of connecting and broadcasting from a local radio station. Without this principle and concept, we would not have the AM radio that we do today, which can also be said for FM radio as well, but with a slightly different operation process. The more we understand what AM radio is, how it works, and what the advantages are, especially in today’s society where radio is not used as often, the more we can really understand why it’s so important.

The Advantages of Using AM Radio

There are multiple advantages that come with using AM radio when compared to FM, which should be remembered today when we think about why AM is still around when most would argue that it’s not needed anymore.

For one, the coverage on an AM receiver’s area is much wider when compared to FM. This is because the atmospheric propagation can stretch a lot farther and wider than the coverage of an FM station or wave. The propagation of AM is the definite choice for long distance ranges without static or too much interference from various towers that are broadcasting FM or another AM station.

The circuit of AM is less complex and a lot cheaper when compared to FM, which has an unlimited bandwidth, while AM has a more limited bandwidth.

To go further in depth for the biggest advantage of AM radio, the signals are further reflected straight back to the ionosphere layer of the earth, which means that the signals are able to reach thousands of miles from the initial source. Therefore, the coverage of AM compared to FM is drastically better and wider.

Selecting the Best AM Radio

Finding an AM radio that will suit your needs and bring the best quality to the table can be difficult, mostly because they are not mass produced anymore and are typically being phased out by radios that offer FM radio capabilities a lot more, but they are still around!

Any quality radio must have shortwave capabilities that bring both AM and FM stations to light but move toward one that is better known for AM instead of FM. That way you will get more bang for your buck in terms of what you’re looking for. An older radio may have the durability you need, but newer versions ensure that you’ll have more channels, so try not to go for one that is too old or too new.

Antennas are a must for AM radio because they help to clear up interference and bring more stations in, even though it probably already has more than enough. Even if you have a cheap radio that is poor quality, an antenna is a big game changer and will turn it into a better quality machine.

AM Radio is Still Relevant

It’s not just your grandparents and parents listening to AM radio anymore, even though it’s been somewhat phased out by FM. AM is still vastly popular for the many talk shows, local advertisements, and even older, classic music stations that AM radio incorporates.
