What is an AM FM radio receiver?
A portable battery-powered AM/FM broadcast receiver, used to listen to audio broadcast by local radio stations. A modern communications receiver, used in two-way radio communication stations to talk with remote locations by shortwave radio.
What is the difference between AM and FM receiver?
In AM, a radio wave is known as the ” carrier” or “carrier wave” is modulated in amplitude by the signal that is to be transmitted. In FM, a radio wave is known as the “carrier” or “carrier wave” is modulated in frequency by the signal that is to be transmitted.

What is the difference between AM radio and FM radio?
The difference is in how the carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of the signal is varied to incorporate the sound information. With FM, the frequency (the number of times each second that the current changes direction) of the carrier signal is varied.
How long will FM radio be around?
Radio stations will be allowed to continue broadcasting via analogue for another decade, the government has said, after several FM and AM commercial radio licences were set to expire from early 2022.
How far does FM radio travel?
VHF radio waves usually do not travel far beyond the visual horizon, so reception distances for FM stations are typically limited to 30–40 miles (50–60 km). They can also be blocked by hills and to a lesser extent by buildings.
Does AM or FM travel further?
FM radio waves also travel horizontally and skyward. However, due to the higher frequency of the carrier waves, the waves that go skyward are not reflected. They pass through the atmosphere and into space. Although AM waves can be received at greater distances than FM waves, FM.
What are the advantages of AM over 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.
Why is FM more popular than AM?
FM uses a higher frequency range and a bigger bandwidth than AM. Each FM station is allocated 150 kHz of bandwidth, which is 15 times that of an AM station. This means that an FM station can transmit 15 times as much information as an AM station and explains why music sounds so much better on FM.
Which brand of radio is the best?
The best radio brands in the world

Are Sangean radios any good?
They’ve all been very good radios. Sangean is equal in quality to Panasonic and Sony. I definitely recommend this radio over the Tivoli Model One.
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.
What does AM and FM stand for on the radio?
AM and FM modulated signals for radio. AM (Amplitude Modulation) and FM (Frequency Modulation) are types of modulation (coding). The electrical signal from program material, usually coming from a studio, is mixed with a carrier wave of a specific frequency, then broadcast.
Is AM radio dead?
Traditional AM/FM radio is still around, but with a dwindling audience. The graph below, from online statistic site Statista, shows the average daily media use in the US over the past four years. Radio usage, represented by the green trend line, has been steadily declining.
