about 88 to 108 MHz.
Example: FM Radio The frequency band for FM radio is about 88 to 108 MHz. The information signal is music and voice which falls in the audio spectrum. The full audio spectrum ranges form 20 to 20,000 Hz, but FM radio limits the upper modulating frequency to 15 kHz (cf.
How far can FM radio reach?
VHF radio waves usually do not travel far beyond the visual horizon, so reception distances for FM stations are typically limited to 3040 miles (5060 km).
What is the frequency range of FM radio in India?
1.2 At present, analog terrestrial radio broadcast in India is carried out in Medium Wave (MW) (5261606 KHz), Short Wave (SW) (622 MHz), and VHF-II (88108 MHz) spectrum bands. VHF-II band is popularly known as FM band due to deployment of Frequency Modulation (FM) technology in this band.
Which is better AM or FM?
FM has better sound quality due to higher bandwidth. AM radio ranges from 535 to 1705 KHz (OR) Up to 1200 bits per second. FM radio ranges in a higher spectrum from 88 to 108 MHz.In AM radio broadcasting, the modulating signal has bandwidth of 15kHz, and hence the bandwidth of an amplitude-modulated signal is 30kHz.

What is private FM?
Last fortnight, the government allowed private FM channels to broadcast English and Hindi news bulletins from state-owned radio network All India Radio (AIR).While private FM stations are allowed to carry AIR news bulletins simultaneously, they also have the option of deferring them by 30 minutes.
Why does radio travel further than FM?
AM broadcasts use longer wavelength radio waves than FM broadcasts. Because of their longer wavelengths, AM waves reflect off a layer of the upper atmosphere called the ionosphere.
Why FM is used?
FM is commonly used at VHF radio frequencies for high-fidelity broadcasts of music and speech. Analog TV sound is also broadcast using FM. Narrowband FM is used for voice communications in commercial and amateur radio settings. In broadcast services, where audio fidelity is important, wideband FM is generally used.
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.
How far can a 10w radio transmit?
Thus the typical ranges with around 400 MHz frequency range with 1 W transmitter power are up to ~30 kilometers and up to ~80 kilometers with 10 W transmitter power. See sample picture of a RF link functional factors at the end of this document. The links can be extended by using repeater radio stations.
How far can a 5000 watt radio station reach?
Line of Sight is everything. Let’s see, if it’s 1 watt = 1 mile, my, that means that a nice FM broadcaster, with 5000 watts, can get 5000 miles…
How far can a 4 watt radio transmit?
Transmitter power is limited to 4 watts in the US and the EU. CB radios have a range of about 3 miles (4.8 km) to 20 miles (32 km) depending on terrain, for line of sight communication; however, various radio propagation conditions may intermittently allow communication over much greater distances.
Who invented FM radio?
Edwin Howard ArmstrongArmstrong, in full Edwin Howard Armstrong, (born December 18, 1890, New York, New York, U.S.died January 31/February 1, 1954, New York City), American inventor who laid the foundation for much of modern radio and electronic circuitry, including the regenerative and superheterodyne circuits and the frequency modulation

What is the 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 is the range of shortwave radio?
Shortwave radio is radio transmission using shortwave (SW) radio frequencies. There is no official definition of the band, but the range always includes all of the high frequency band (HF), which extends from 3 to 30 MHz (100 to 10 metres); above the medium frequency band (MF), to the bottom of the VHF band.
Is FM transmitter legal in India?
