Any new committee, commission, council, authority, or agency that was handed the
job of creating a system and procedure, in place of the FCC, for allocating frequencies
to all the radio services that need and want them, would begin in total chaos. After
years spent inventing some sort of device that could function acceptably as a wheel,
adjusting, modifying, revising, litigating, defending, streamlining, and tweaking its
system, it would eventually arrive at a system identical to the one that's in place today.
That's my opinion. I could be wrong.

That's the frequency band that international telecommunications meetings and the FCC decided to allocate to FM broadcast. As a result of that decision, all FM broadcast stations in the US have carrier frequencies in that range. If they applied for a license to broadcast on a frequency outside of that range, it wasn't granted, and they soon got the idea. The manufacturers of radios, being a pretty smart bunch, realized right away that if all of the FM broadcast stations were on frequencies in that range, then they'd be smart to build their products with the ability to receive FM broadcast in that range. If you play around with a receiver that can receive frequencies outside that range, you'll hear TV channel 6 between 82-88 MHz, and aircraft navigation and communication above 110 MHz.
That would be hard to answer, especially without a definition of "typical".We presently generate and detect radio signals, for communication and variousother applications, over a range of frequencies of perhaps 50 KHz to 300 GHz,corresponding to wavelengths between 1 millimeter and 6 kilometers.
yes umm you have too hook the antenna to the hole ane wrap the copper wire around it-------------------------------------------------------- It would work OK for FM radio frequencies (88-108 Mhz) in metropolitan areas, but poorly for AM radio which is 535-1600 Khz

A superheterodyne receiver is a Radio Frequency receiver method that multiplies the received signal frequency with a local oscillator frequency to get frequencies that are the sum and difference of the 2 frequencies. For example, if the received signal is 5MHz and the local oscillator frequency is 4MHz, they are multiplied together. 1MHz and 9MHz frequencies would be gotten. Usually the 1MHz is the Intermediate Frequency (IF). It will be admitted (through a band pass filter) later passed through the required electronic circuits for proper processing. There is also the method of the Variable Tuned Filter.
Typical questions would be about the range and the components used, as well as what frequencies it is designed to receive.
RF refers to 'radio frequency'. A selector switch would select a different range of radio frequencies at each of its positions. RF selector switches would be found on short wave receivers and transmitters.
Frequencies around 2.4 GHz and 5 GHz are commonly used for Wi-Fi, Bluetooth, and other wireless communication technologies in English-speaking countries. AM and FM radio frequencies are also widely available for listening to English language broadcasts.
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.
In radio transmission, you could theoretically transmit radio signals at audio frequencies. However, because the wavelength of electromagnetism at audio-like frequencies is Huge and the frequency of a radio transmitter dictates the size of the antenna and the power requirement, you would need A Very Big Antenna and a Very Big Power Supply to do this. So, we've learned to transmit at higher "carrier" frequencies, modulating either the amplitude or frequency of the carrier signal with our audio and subtracting the carrier at the receiver end.
microwaves are more penetrative than gamma rays, UV radiation and visible light, but less so than radio waves.
It's possible that the radio frequencies used for mobile phones - were already in use in Cuba. The delay in introducing any service would be dependent on how quickly they could move other users to alternative frequencies.
In Java we need not allocate memory manually. The JVM would take care of allocating as much memory that your objects would require automatically.
Infrared is directly below, next is x-ray, next is radio.
No, that is completely unrelated.
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 weaknessis the ability of consumer-grade receivers to separate stations whose frequenciesare close together.)
Libertarians are for ultimate personal freedom with the least amount of government control. Therefore a libertarian government would not interfere in someones choice in having an abortion unless the embryo was deemed capable of living outside the womb and therefore would be considered as being a living being.
