    How Does FM Radio Work?

    Satellite Radio

    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

    How to Build an FM Radio?

    Portable Digital Radi

    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

    • 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 Portable AM FM Radio

good overall radio
00:00:00 04-25-2011
Very good radio for size and price. Somewhat difficult to tune since stations are too close together in such a short dial. <br/>A little sensitive to interference, but just move it or turn it and it will sound great. <br/>Equally good in AM and FM. <br/>Good finish.

Great little radio for the money!
00:00:00 04-17-2011
All the other reviews I've read about this little radio were right on. It's very small and lightweight, looks like it wouldn't work well at all, but believe me it does! My previous radio was three times the money and yet the reception on this one is amazing. Highly recommended if you just want something small and inexpensive, yet powerful enough to be useful.

When the electricity goes out...Radio waves are going to be the most likely form of communication when these things happen..This Radio works great nice reception,long telescoping antenna,easy operating controls

Portable Radio Review
00:00:00 04-03-2011
This radio brings in distant stations, sounds good, and takes up little space. The controls are easy for me to use. These were the qualities I was looking for so I am pleased to purchase this radio.

This item was used by someone else in our department. They asked me to order it for them, but your service was great, as usual! :-)

Great little radio
00:00:00 03-06-2011
I bought this radio based on others' recommendations and I'm not disappointed. I wanted to replace an older portable I still have that was sounding bad due to getting wet. This little radio is perfect - easy to use/tune, good sound for a portable, at a great price. I recommend this radio for anyone wanting a small portable.

Radio Does the Job!
00:00:00 02-21-2011
I bought this to listen to my fav morning show when I walk in the mornings. I really like the radio, I read a few reviews and it seemed like this was the best one for the money. I am extremely happy with the speaker, it's very loud. However, the antenna is almost TOO good, to explain, if you move slightly it will pick up other stations, which is a little annoying when you are walking. Haven't had it long enough to judge battery life. Also, not sure if it's my headphones or the radio, but it is very loud on the lowest setting. Great buy for the money though, I HIGHLY RECOMMEND THIS.

Very good reception
00:00:00 02-07-2011
Needed a basic portable here on Cape Cod that would bring in signals I otherwise was having difficulty accessing; reception is much improved with this Sony radio. It is very lightweight. The only negative so far is in the design as the bottom is not flat enuf to stand the radio upright easily. I lean it on something nearby.
