How far does FM radio travel?
Reception distance 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).
What are the advantages of FM over AM?
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.
Why FM channels are so popular?
The Reach of FM Radio in India Radio remains the most inexpensive, earliest and the best portable mode of telecommunication available to all. The audience engagement is better with radio because it does not have any prerequisite qualification level to access and understand this medium.
What is the main disadvantage of FM over AM?
What is the main disadvantage of FM over AM? Explanation: The disadvantage of FM over AM is that in frequency modulation large bandwidth is required. While, in case of advantages, FM is less prone to noise interference and has lower power consumption compared to AM.
What is the main difference between AM and FM?
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.
What are the advantages and disadvantages of FM?
In Fm receivers the noise can be reduced by increasing the frequency deviation and hence Fm reception is immune to noise as compared to AM reception, 2.Fm transmitters are highly efficient than AM transmitters as in Am transmission most of the power goes waste in the transmitted carrier.
In what decade did FM radio become more popular than AM radio?
1970sBy the 1970s, FM audience size surpassed that of AM, and the gap has been growing ever since. Today over 2,000 FM stations broadcast in the United States, and FM signals are commonly used for microwave relay links and space communications.
What are the limitations of AM?
Disadvantages of Amplitude Modulation:An amplitude modulation signal is not efficient in terms of its power usage. … It is not efficient in terms of its use of bandwidth. … AM detectors are sensitive to noise hence an amplitude modulation signal is prone to high levels of noise.Reproduction is not high fidelity.
How do radio stations know you’re listening?
There are radio ratings services, like Arbritron, and Nielsen. The company polls a certain number of radio listeners in a certain region. Then by statistical analysis, the ratings firm, extrapolate the results of the survey, and determine how many people in the region are listening to each individual radio station.
Is AM radio dead?
No, AM is not dead. But if you really want to improve it, bring back a technology that already “failed” … AM stereo.
Will FM radio go away?
“It won’t go away. There will be far fewer stations, both AM and FM, but those that survive will find alternate means of survival. The horse did not become extinct, but there are far fewer horses on the earth today than one hundred years ago.”
What does DAB stand for?
Digital Audio BroadcastingDAB stands for Digital Audio Broadcasting. It is a digital radio service which is broadcast from a UK-wide network of transmitters. It uses digital technology which enables broadcasters to package together several radio stations; this is called multiplexing.
What came first AM or FM radio?
This type of transmission is called amplitude modulation (AM). It appears to have first been thought of by John Stone Stone in 1892. Many years after Armstrong’s invention of the super heterodyne, he solved radio’s last major problem, static, by inventing frequency modulation (FM), which he successfully tested in 1933.
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.
Why is AM radio not used?
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.
When did FM become popular?
March 1, 1941FM radio was assigned the 42 to 50 MHz band of the spectrum in 1940. There was interest in the new FM band by station owners. On March 1, 1941 W47NV began operations in Nashville, Tennessee, becoming the first modern commercial FM radio station.
Which is stronger AM or FM?
FM radio, always remains at constant amplitude, so signal strength does not change. FM uses a higher frequency range and a bigger bandwidth than AM. … 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.

What is the oldest radio station in the United States?
KDKAKDKA in Pittsburgh, most often cited as the first radio outlet in the United States, had begun as the amateur station 8XK in 1916, but it was forced off the air in World War I. It reappeared on November 2, 1920, as a “commercial” voice-and-music…
Why do FM stations end in odd numbers?
FM radio stations end in odd numbers to prevent interference. The reason they are odd numbers rather than even numbers is that 1 (odd number) is the first number we start counting from, not 0 (even number). FM radio stations in the U.S. transmit in bands between 88.0 megahertz (MHz) and 108.0 MHz.
