In the USA, if you're listening to a commercial AM station, then its assigned carrier
frequency is a multiple of 10 KHz between 550 and 1,700 KHz. If it's a commercial or
educational FM station, then the carrier frequency is between 87.9 and 107.9 MHz,
always with a single odd digit after the decimal point.
It doesn't matter where the radio is located ... in the car, in the house, in your pocket, etc.
If you're listening to one of the subscription 'satellite' radio services, then these numbers
don't apply.
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.
Any radio signal, regardless of its frequency, can be amplitude-modulated in order to add information to it. In the US, commercial broadcast AM radio stations operate on carrier frequencies between 540 KHz and 1.7 MHz.
Explain the need for carrier frequency stability in radio transmitters?
That's not exactly true. Any frequency you choose has several radio stations on it,but just not in the same city.Frequency is what your radio uses to separate the individual stations. If two stationsin the same city transmitted on the same frequency, your radio couldn't separate them.When you tuned to that frequency, you'd hear both of them at the same time, and youcouldn't understand either one.Listen to the 27 MHz 'Citizen's Band' some time.

FM radio stations transmit on VHF band, short for "Very High Frequency", ranging from about 87 to 108 MHz.
Frequency Modulation must have a carrier whereby the frequency can be modulated by the signal
carrier wave
There are dozens of radio stations working on different radio frequency. FM frequency is liked and listened to by most of Pakistanis.
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.
The digital radio does not hold the stations because the frequencies of the stations keep changing from one frequency to another.
Your radio separates the stations according to their frequency (wavelength).
