    How Does FM Radio Work?

    Sound Waves and Frequency:

    • All sound energy is in the form of a wave. The frequency of a wave is the measurement of the number of cycles that it undergoes in a given time frame. Hertz is a measurement of frequency that depicts the number of wave cycles per second. FM signals are measured in megahertz so an FM signal of 97.5 relates to 97,500,000 waves/second

    Frequency Modulation:

    • FM actually stands for Frequency Modulation. FM signals use various frequency levels that reproduce the sound of the originating source (i.e. music). You've probably noticed that FM contains all your music channels while AM radio is limited to news and talk programming. This is because frequency modulation allows for the transmission of the greater range of frequencies (high and low sounds) contained within music.

    Transmission:

    • FM radio originates at the broadcast source (radio stations). These stations use large antennas to send out their broadcast signal. Electrical charges are pushed up and down the broadcast antenna at a rate that relates to the carrier frequency. The movement of electrical charges creates an electromagnetic field which sends out
    • electromagnetic waves. The waves are sent in all directions. Carrier waves are sent out at a frequency that can be detected by your antenna (the radio station number). They carry sound information that includes the different frequencies of the original broadcast

    Reception:

    • The electromagnetic carrier wave travels through the atmosphere until it is picked up by a receiver antenna (i.e. your car radio antenna). At this time the wave causes electrical charges to be pushed up and down your antenna and on into your receiver. The receiver decodes the modulated frequency information and then passes it to the speakers

    Processing and Hearing:

    • The speaker vibrates according to the processed frequencies and pushes air molecules that recreate the original sound waves and pass them to your ears. You hear the music or talk that was sent in the original broadcast. Since electricity works at the speed of light, this process, from broadcast to listener, is instantaneous

    Loss of Signal:

    • You've probably noticed, particularly if you listen to FM radio in the car, that eventually you will lose your signal. The simple reason for this is that the short wavelength of FM radio waves cause them to travel in straight lines. The earth, however, is curved. Therefore, as the earth curves, FM waves continue in a straight line into the atmosphere and are no longer receptible. The short waves are also affected by obstacles like mountains

    Differences Between AM and FM Receivers:

    • In an AM transmission the carrier wave is constant in frequency and varies in amplitude (strength) according to the sounds present at the microphone; in FM the carrier is constant in amplitude and varies in frequency. FM is also used in television sound systems. In both radio and television receivers, once the basic signals have been separated from the carrier wave they are fed to a loudspeaker or a display device (usually a cathode-ray tube), where they are converted into sound and visual images, respectively.

    How to Build an FM Radio?

    • A radio provides signal transmission via the use of electromagnetic waves. The frequencies a radio uses are lower than those of visible light. A German scientist by the name of Heinrich Hertz was the first to detect and product radio frequencies, in 1888. Radios are still in wide use, even in this internet age. Building a simple FM radio only requires a small amount of time and materials. Although this radio is fully functioning, it isn't very pretty

    Instructions:

    • Solder the ferrite loop to the variable capacitor. Only solder the ferrite wire that is painted black. Make sure you are soldering the ferrite loop to the center lead of the variable capacitor
    • Solder the unpainted wire of the ferrite loop to the variable capacitor's right lead
    • Solder the germanium diode to the same right lead of the variable capacitor as the unpainted wire of the ferrite loop. Only connect one end of the germanium diode
    • Solder one end of the piezoelectric wire to the other (free) end of the germanium diode
    • Solder the other end of the piezoelectric wire to the variable capacitor's center lead
    • Take note of the red-painted wire of the ferrite coil. Use an alligator clip to attach it to the antenna wire
    • Use the remaining alligator clip lead to attach the green-painted wire of the ferrite coil to a good ground. You can use a cold water pipe for the ground

    • 1 x Radio

Lovely Sound.Labels are in Chinese though.
16:38:55 12-15-2011
Sound & Feel is generally very Good

Chinese Labels needed to be deciphered and relabled to make it easier to use.

Some digital preset buttons would make this almost perfect. And the choice of a Blue or Black one.

Beautiful Machine
12:40:08 12-05-2011
Beautiful radio, superb sound and absolutely love it. Also comes with 240 direct power cord so can be use immediately with simple adaptor which Dino supplied

Unfortunately all the markings and manual is in Chinese! But it is sold in America as an Eton S350 and you can download manual in English from their site

None!

Portable radio
00:00:00 11-13-2011
I have owned this radio before. It has changed little in the past 10 years. It is well priced from Amazon, and overall a good buy. Digital tuning would help and why Sony does not do this is hard to accept. It is simple and not loaded with gizmos.

As long as you are mindful of this when turning the radio on or off, there is no problem with this radio. <br/>I would buy another one if I needed another radio.

A Great Radio
00:00:00 11-06-2011
This radio has really great reception for the station I listen to. (I haven't tested it on other stations.) The sound quality is great. The controls are very easy to operate. And the footprint is small, which is good, because it sits on my desk, and there isn't much free space on my desk.

Great little radio
00:00:00 11-04-2011
I bought this as a gift for a friend who requested it to listen to ball games. She said it comes in perfectly, and the reception has been great out on her deck. It is lightweight, but kicks out quality sound.

Nice
00:00:00 11-01-2011
When I purchased this radio, I wanted one that would have a good tuner section, with good sensitivity and selectivity on the fm side. I have not been disappointed.

If you want a solid, dependable portable radio with no digital display or other fancy yet unnecessary features, look no further, you want the Multi Band Radio. It works well.
