What is the frequencies in the range of RF waves used by commercial radio broadcasting stations?

Each country has different frequency bands allocated for AM and FM radio. In the U.S. AM takes up the range from 535KHz to 1605KHz. FM radio takes 88.0MHz to 108.0MHz.
Each radio station then receives a slice of that frequency band, regulated by the FCC. Each station is typically given a frequency far from all other stations. For example, three stations would be given the frequencies 93.3MHz, 94.5MHz and 96.1MHz. In theory, the stations could be closer (ie 94.3MHz, 94.5MHz and 94.7MHz) though this is rarely done because each station would then cause more interference to its neighbors.
(The stations don't actually 'cause interference' to their neighbors. The weakness
is the ability of consumer-grade receivers to separate stations whose frequencies
are close together.)

-- Commercial AM radio stations operate with carrier frequencies spaced every 10 KHz
between 550 KHz and 1700 KHz.
-- Commercial FM radio stations operate with carrier frequencies spaced every 200 KHz
between 88.1 MHz and 107.9 MHz.

What are the SAP addresses in FM radio broadcasting?
SAP addresses are the FM frequencies, like FM 91.4.
The frequencies 88.1 - 91.9 FM are?
Generally FM radio range is from 88 MHz to 108 MHz. Frequencies are issued to commercial broadcasters by a government authority. Broadcasters need a licence to use a frequency. This description may change depending on the country.
Why dont broadcast stations transmit at audio frequencies?
1) If information was transmitted at audio frequencies, then you would actually hear the signal. This would be identical to a speaker playing a song on your stereo. 2) Audio frequencies, in the world of radio frequencies, are long wave-length, low energy signals that can't travel long distances. Again, that's why you can only hear someone's stereo from within eyesight of the system. Human ears can detect from about 3Hz up to around 20KHz (some better than others). 3) True radio frequencies start at in the 100Khz range. This is your most basic radio that uses amplitude modulation (aka AM radio). Many people today that listen to the radio listen to frequency modulated (FM) stations. The difference between AM and FM is beyond the scope of the answer to this question. Being a higher frequency, the signals have more energy and can travel farther distances than audible frequencies. 4) Audible frequencies (sounds the human ear can pick up) can only "transmit" amplitude (loudness or volume) and frequency (high or low pitch). However, higher frequencies, such as those used for radio, can carry much more information than the volume and pitch of a signal. This is a direct result of radio frequencies being harmonics (integer multiples) of audible signals. For instance, if a radio signal has a frequency 20 times higher than the audio signal it is transmitting, then that radio signal can not only carry the audio signal, it can also carry other information, such as information about the broadcast station. A radio signal can "encode" information within the signal allowing more information to be carried than just the audio signal itself.
A technical facility for broadcasting via wire?
Coded is a television and radio program facility for broadcasting via wire. These facilities are exempt from many broadcasting regulations.
What is are unlicensed radio frequencies?
Those which you can use for free, for instance a tv remote control uses such frequencies.
Which one of the following frequencies falls in the range of RF waves used by commercial radio broadcasting stations?
See page 101 of your study unit. In there you will find that radio frequencies used by commercial radio broadcasting stations range from about 550,000 Hz to 1,700,000 Hz.
Which frequencies falls in the range of RF waves used by commercial radio broadcasting stations?
In the USA ... -- Commercial AM radio stations operate with carrier frequencies spaced every 10 KHz between 550 KHz and 1700 KHz. -- Commercial FM radio stations operate with carrier frequencies spaced every 200 KHz between 88.1 MHz and 107.9 MHz.
What frequencies falls in the range of RF waves used by commercial radio broadcastings stations?
The frequency that falls in the range of RF waves used by commercial radio broadcasting stations is 3 kHz to 300 GHz. This is the frequency of radio waves and the alternating currents that carry them.
What is the frequency used by most commercial radio stations?
In the USA: All commercial AM stations are assigned frequencies in the band 550-1620 KHz, in increments of 10 KHz. All commercial FM stations are assigned frequencies in the band 88-108 MHz, in increments of 100 KHz (0.1 MHz).
What is the frequency band used by most commercial radio stations?
In the USA: All commercial AM stations are assigned frequencies in the band 550-1620 KHz, in increments of 10 KHz. All commercial FM stations are assigned frequencies in the band 88-108 MHz, in increments of 100 KHz (0.1 MHz).
What frequencies of RF waves are used by commercial radio broadcasting stations?
In the US, the AM broadcast band occupies 550 - 1,700 KHz, with assigned carrier frequencies spaced by 10 KHz. The FM broadcast band occupies 88 - 108 MHz, with assigned carrier frequencies spaced by 200 KHz (0.2 MHz) starting at 88.1 MHz.
What are the frequencies of the various radio stations in Israel?
The frequencies of the various radio stations in Israel are between 87.6 and 106.9 FM. Some of the popular stations are Kol Hamusica, Radio Jerusalem, Reka and so many more.Ê
When you listen to a radio why are you able to hear only one station at a time rather then all stations at once?
Because different radio stations broadcast at different frequencies, and the radio tuner lets you decide which frequencies to listen to. Radio station owners have to buy the rights to use a particular frequency within a particular area. When you are driving sometimes you will hear two stations overlapping as you move out of the range of one station and into the range of another that is broadcasting on the same frequency.
AM radio frequency?
An AM-modulated transmission can be operated on any radio frequency. In the USA, AM commercial broadcast stations are assigned carrier frequencies between 550 KHz and 1.7 MHz.
Which radio station broadcasts a longer wavelenght 93.9 FM or 104.3 FM?
"Longer wavelength" always means lower frequency.
Can you give the frequency for all radio stations?
Yes we can. At least for the commercial broadcast stations in the USA.AM stations:Carrier frequencies are at every 10 KHz, between 550 KHz and 1700 KHz.FM stations:Carrier frequencies are at every 0.2 MHz, between 88.1 MHz and 107.9 MHz.
What is Public broadcasting and commercial broadcasting?
Public broadcasting is TV, Radio, etc funded by an official or governments, with No paid advertisements. Commercial broadcasting on the other hand is TV funded by paid advertisements and contain advertisements during the TV or radio times.
