You're using a radio designed to receive the US commercial FM broadcast band.
Radio stations intended for public broadcast and carrying the type of programing
that they do, are licensed to operate in that frequency range. If you were working
with some other type of radio service ... amateur, public safety, common carrier ...
then that service would operate in a different frequency band, and you would use
a different type of receiver ... one that works in the band where you need to be able
to hear what's going on.
What else can I help you with?
What is the wave frequency of an FM radio wave?
FM radio is transmitted anywhere in the spectrum of 88Mhz to 108Mhz
Will amplitude modulated waves go more distance or frequency modulated waves?
The method of modulation has very little to do with the distance traveled, this is more dependent upon the frequency of the carrier. As the frequency gets higher the wave takes on more and more the characteristics of light. For example microwaves need to have the receiving dishes (antennae) in line of site with the transmitter.In practical circumstances it appears the AM travels further but that is only because AM broadcasts at lower frequencies (typically 526KHz to 1625KHz) (MF) and FM at higher frequencies (typically 88MHz to 108MHz)(VHF)
What is the wavelength range for the FM radio band (88MHz-108MHz)?
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.
Which atmosphere layer contains electrically charged particles that radio waves?
The ionosphere. To clarify, only the low-frequency radio waves incorrectly called "high-frequency" or "HF" of about 50MHz and below are reflected. "Very High Frequency" VHF signals are not reflected, but go straight off into space. For example, in the "AM" commercial broadcast spectrum, the transmission is reflected back to the Earth and is receivable for great distances, a phenomenon that used to be called "skip". AM signals are in the band of 550KHZ to 1.6 MHz. "FM" stations in the band from 88MHz to 108MHz are only received by "Line of sight" transmissions.
What layer is hit by the sun's ultraviolet rays and cause the air particles to become electrically charged?
The ionosphere. To clarify, only the low-frequency radio waves incorrectly called "high-frequency" or "HF" of about 50MHz and below are reflected. "Very High Frequency" VHF signals are not reflected, but go straight off into space. For example, in the "AM" commercial broadcast spectrum, the transmission is reflected back to the Earth and is receivable for great distances, a phenomenon that used to be called "skip". AM signals are in the band of 550KHZ to 1.6 MHz. "FM" stations in the band from 88MHz to 108MHz are only received by "Line of sight" transmissions.
How far can 4 meter 5 watt vhf 66mhz to 88mhz transmit up to?
The transmission range of a 4-meter, 5-watt VHF radio operating between 66 MHz and 88 MHz can vary based on several factors, including antenna type, terrain, and atmospheric conditions. Generally, under optimal conditions, such a radio might achieve a range of 10 to 30 kilometers (6 to 18 miles) in flat terrain with minimal obstructions. However, in urban areas or with significant obstacles, the effective range could decrease substantially. Always consider local regulations regarding transmission power and frequency use.
Lowest number on FM radio?
The lowest number marked on the dial is most likely 88 .The lowest carrier frequency assigned to FM stations in the US is 87.9 .
