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.
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).
Some popular Mexican radio stations are Radio Formula FM 104.1, Los 40 Principales MX, Stereo 97.7 and Alfa Radio. All radio stations are located in Mexico City.

93.5 is simply the frequency that the station transmits at. Dozens of stations can use this same frequency around the country. In the Related links section below is a resource to find radio stations near where you live. Enter your zip code, and it will display a list of nearby stations and their frequencies. Click on their callsign to bring up the station's web page.
The only way your radio has of separating one station out of the pile, and letting you listen to the one single station you want to hear, is by frequency. If two stations are on the same frequency, then your radio hears them both when it's tuned to that frequency. If there are 100 of them, you hear all 100. The result of that is . . . well, just listen to CB some time.
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.
Yes, resonance can work in tone detection. You tune the resonant circuit to the frequency you want to detect and follow it with an amplitude detector. Amplitude above your design threshold value means there is signal frequency within your passband. This is how the original crystal radio worked. The resonant frequency was the frequency of the radio station desired. All other frequencies (radio stations) were rejected by the bandpass filter.

AOL Radio offers many different radio stations. AOL Radio has over one hundred fifty stations that play all kinds of different music generas. AOL Radio started in 2001.
All radio stations must keep logs for the FCC by law...and offer Proof of Performance if needed. All public music users (radio, tv, stadiums, restaurants, clubs, etc.) have to license with royalty collection agencies like ASCAP or BMI. Terms of their agreements vary depending on size and frequency of use.
That number is the 'frequency' of the radio waves transmitted by that station ...the number of times the wave wiggles in one second. "102 megahertz" means102 million every second.Right now, in your room and in the air around you, there are thousands of radiosignals from AM and FM broadcast stations, police cars, taxis, ambulances, cellphones, airplanes calling the air-traffic controllers, TV stations on the groundand TV satellites in space, GPS satellites, and RADARs watching for rainstorms.The only way your radio is able to pick out the one you want to hear and discardall the others is to separate them according to their frequencies. If there arefour radio transmitters all close enough to you and all on the same frequency,then your radio can't separate them, and you hear them all at the same time.That's why there are never two TV stations in the same city on the same channel,or two radio stations on the same number.
There's no difference between a frequency-modulated wave and an amplitude-modulated wave. Either kind can be generated and transmitted with any wavelength you want. In the USA, however, AM broadcast stations are licensed to operate only in the band 550-1700 KHz, and FM broadcast stations are licensed to operate only in the band 88-108 MHz. So for ordinary programs that you listen to on an ordinary radio, the AM stations all have longer wavelengths than the FM stations have.
