What are the applications of AM and FM?
Nevertheless many people are moving to high quality forms of transmission like frequency modulation, FM or digital transmissions. Air band radio: VHF transmissions for many airborne applications still use AM.. It is used for ground to air radio communications as well as two way radio links for ground staff as well.
Is there an app for AM FM radio?
Because our app is fast and can run on all your Android devices, if you have a cell phone or a tablet you can listen to radios from all over the world live! Download Radio FM AM Free – Radio World online + Radio App and enjoy your favorite radio stations right on your fingers!
What is AM radio mostly used for?
AM broadcasting is radio broadcasting using amplitude modulation (AM) transmissions. It was the first method developed for making audio radio transmissions, and is still used worldwide, primarily for medium wave (also known as “AM band”) transmissions, but also on the longwave and shortwave radio bands.
How can I listen to AM radio on my phone?
As long as you have a smartphone, you can download FM radio apps to access thousands of live and local radio stations from your phone. One of the most popular is called iHeartRadio. It’s completely free to download¹ and listen and offers thousands of live FM and AM radio stations that you can tune into at any time.
Why FM is used in broadcasting but not PM?
Like FM, PM minimizes various types of interference to broadcast reception at frequencies below 30 MHz. The two techniques are commonly used together. FM cannot be applied during the amplification of a sound signal in broadcasting, and so PM is used instead.
What are the advantages of FM?
The main advantages of FM over AM are:
- Improved signal to noise ratio (about 25dB) w.r.t. to man made interference.
- Smaller geographical interference between neighboring stations.
- Less radiated power.
- Well defined service areas for given transmitter power.

You may not know this, but many, if not most, local AM and FM radio stations stream their broadcasts over the Internet. These services/apps, such as iHeartRadio or TuneIn, let you listen to practically any radio station in the United States, and many more globally.
Why don’t we use AM radio?
The decline in AM audio was due more to regulation than to method of modulation. One aspect of radio not understood by most listeners is the concept of occupied bandwidth, or the amount of spectrum that a station uses to transmit its signal. It displays signals within a specified range of frequencies.
Why is AM radio so bad?
AM stands for Amplitude Modulation and has poorer sound quality compared with FM, but it is cheaper to transmit and can be sent over long distances — especially at night. The lower frequencies of the band we use for AM signals creates a wavelength that is extremely large.
Is AM or FM Better?
With FM, the frequency (the number of times each second that the current changes direction) of the carrier signal is varied. FM signals have a great advantage over AM signals. Both signals are susceptible to slight changes in amplitude. With an AM broadcast, these changes result in static.
Can my phone pick up FM radio?
If your phone has a built-in FM radio tuner, but didn’t come with a stock app that lets you access it, then NextRadio is your best bet. The set-up process is simple—just install the app, then if your device is supported, you’ll be able to tune in on live FM broadcasts.
How can I listen to radio without using data?
To listen to FM radio without data, you need a phone with a built-in FM radio chip, an FM radio app, and earbuds or headphones. NextRadio is a good Android app that lets you listen without data (if the phone has an FM chip) and includes a basic tuner.
Do Android phones have FM radio?
There are no hardware changes, as FM receivers are already present in most smartphones, but not all smartphone makers activate them. NextRadio is a broadcaster-backed app that works with smartphones containing active FM chips (including devices from HTC, Motorola, and LG), letting users listen to local radio stations.
