What frequency does RF waves fall in used by commercial radio broadcasting stations?

Answer 1

There are basically two radio broadcast bands as we know them. One is the AM (amplitude modulation) band, and the other is the FM (frequency modulation) band. The AM band is from 520 KHz to 1700 KHz (0.52 MHz to 1.7 MHz). The FM band is from 87.5 MHz to 108.0 MHz. Other bands are used commercially, but these two bands represent the broadcast bands used in the U.S.

Note: 1 KHz = 1,000 Hz (Hertz, cycles per second, or cps), and 1 MHz = 1,000,000 Hz

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.

Answer 2

Commercial radio broadcasting ... plain old AM and FM, not TV or "satellite" radio ... is

allocated the frequency bands of 550 KHz to 1650 KHz (AM), and 88 MHz to 108 MHz (FM),

in the USA.

Answer 3

In the U.S., the AM radio band takes up the spectrum from 520 kHz to 1610 kHz. The FM radio band takes up the spectrum from 87.5 MHz to 108 MHz. Other bands are used in different parts of the world. And there are some other definitions of commercial radio that might be used which would require us to block out more chunks of the electromagnetic (EM) spectrum. These vary a bit from area to area as well.

Answer 4

Radio frequency range, as determined by FCC in the US:

AM: 535 kHz - 1.7 MHz

SW: 5.9 MHz - 26.1 MHz

TV: 54 MHz - 220 MHz

FM: 88 MHz - 108 MHz

In addition, all wireless communications use radio waves, ranging from 40 MHz to tens of GHz.

We generate and detect radio waves for purposes of communication, cooking, and

scientific investigation, in the frequency range of roughly 30 KHz to 300 GHz,

corresponding to wavelengths between 10,000 meters and 1 millimeter.

Answer 5

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.

There have been suggestions, and even a few formal approaches to the FCC, to

change these bands, since this question started showing up on WikiAnswers. But

the idea has no serious momentum, and all of the previous repetitions of the answer

still apply.

Each frequency on the following list does:

Answer 7

Commercial AM broadcast uses frequencies between 550,000 Hz to 1,700,000 Hz.

Commercial FM broadcast uses frequencies between 88 MHz to 108 MHz. (million Hz)
