Does Radio Shack fix iPods?

Depending on the Radio Shack we can check to see if the Ipod can be sent out for repair. Its a 20 dollar deposit then the cost to repair once it is sent back.

A better idea is to contact the manufacturer, Apple, since they would stock any parts in need of replacement, and would also honor the warranty, if your iPod was purchased within the past year. The Apple website contains a service FAQ to answer any questions (see link, below).

How do you reenter the radio code in your 1994 Saab?

To acquire the code you will have to contact a BMW dealership and provide them with your vin# and the numbers off the sticker on the back of your radio. To enter the code use the number buttons.

How do you remove golf 5 radio?

You need a special tool set. In a pinch you could make one if you had a template for one. Assuming you have the single din deck, you insert the two tools into the thin vertical slots on each side. Its a thin slot about 8mm high and about 2mm wide. Remove the storage bin above then slide in the tool and when it locks, pull gently and it should slide out. I once cut a peice of sheet metal the right size and inserted it, then gently pulled outward with my fingers in the tape deck opening. Do it gently or you can break the faceplate.

What are the advantages of using optical fiber instead of radio waves to carry signals?

see www.soe.ucsc.edu/classes/cmpe150/Fall05/lecture6.ppt for the answer

AnswerThe biggest is less attenuation (degradation) of signal, so that a message can travel significantly further over an optical fibre than over a copper (twisted pair of coax) cable before it becomes too garbled to understand. In addition, fibre optic cables are generally immune to electromagnetic interference (such as strong electrical or magnetic fields) nearby, while copper cables can have such interference reduce or completely destroy their ability to carry signals. Finally, it is much easier to transmit on multiple channels (frequencies) over fibre than over copper, so a fibre optic cable can handle many more simultaneous message streams than twisted pair or coax.

In short: fibre allows hugely greater distances between endpoints, is practically immune to outside interference, and can handle hundreds or thousands of times more signal channels than twisted pair or coaxial cable.

What is the best way to fix scratched Lp records?

As a kid, in the 60's and 70's, I would fix everyones scratched 45's by gently pressing and holding the needle or stylus in the spot on the record where the scratch occurs. I would go over the same scratched spot of the record, and repress the groove until the skips or scratch clears. I know this sounds crazy, but it always worked. You must have a gentle touch when you repress the groove.

What are the FM radio frequencies?

Depends on the radio, it can be just about anything.

How do you make a radio show interesting?

What came first the telegraph or radio?

I am assuming that you are referencing X-rays as the actual X-Ray Machine, in which case the Radio. There have been X-Ray like devices but more like using light and a reflector, and radios can be simple metal coils that act as receivers.

What are Electromagnetic wave transmitted by a radio station called?

Radio stations that broadcast in the AM to FM range transmit EM waves known justly as radio waves (EM waves with frequencies from 30 KHz to 300 MHz, or wavelengths from 10 km to 1 m).

What radio station is my chemical romance on in Florida?

How is radio waves use in your everyday life?

Here are eight examples:

-- You wake up to the local weather report from the little box on your nightstand.

-- The transducer stuck to your windshield pays your toll automatically as you drive to work.

-- The GPS thing on the dash knows where you are, and tells you when to turn.

-- When you get home, you push the button over the visor to open the garage door.

-- The high-power microwave radio source in the kitchen heats the meat-loaf for dinner

in 30 seconds.

-- After dinner, you clean up your e-mail and send a few tweets, using your wireless internet.

-- Then you settle down to watch the game and a movie on TV.

-- Your cell-phone rings during the game. You take it out of your pocket and look at it

while it rings. You see who's calling, and you don't answer it.

the factory radio should be realy easy to move mine is a 89 f150 lariat so it should be the same now i dident have the part to remove it the best i can say is do what i do rip it out and pray for the best but if you have the extra cash go to kragen auto parts and ask for a CD player removel kit hope this helped you keep trucking

How do you remove the radio on a 1997 Isuzu Trooper?

You have to remove the screws holding the dash faceplate. Once you have removed the faceplate, the radio should have four screws holding it in place.You have to pull the ashtray out and there should be two screws behind it also they are there on the 94 and 95. The switches ( hazzard,wipers headlight etc.)can be pulled off no tools needed for those. As far as the dash faceplate you will need a Phillips and a flat screwdriver. Be gentle!!

WHAT IS CB Radio?

A CB radio is a wireless transceiver that operates on the frequency band called Citizen Band, CB. This band has been reserved for the public. In some countries license is required and in some countries no license is required to operate CB radio. The maximum power limit is 5 Watts. There are 40 channels around 27 MHz in this band.

What are the advantages and disadvantages in using television and radio?

Televised, printed, and radio news have strong benefits in modern society. It allows the general public to stay informed and understanding of current issues in government, culture, and weather patterns. It is also a major method through which people learn of political occurrences that affect their daily life.

Why do radio waves not follow a straight line?

radio waves are affected by a number of environmental conditions which cause the following:

  • refraction
  • reflection
  • absorption
  • diffraction
  • scattering

Radio waves at UHF and above frequencies can be refracted around sharp edge grounded objects such as walls. The effect gets more apparent as the frequency increases.

Reflection of radio occurs if an obstruction is sufficiently dense to deflect radio waves such as aluminium and other metals.

In the case of absorption and material of high density will either block a signal or absorb it if grounded or of sufficient mass. The level of absorption is dependent of the radio frequency emitted or the density of the obstruction.

Earths atmosphere can become ionised be Solar radiation and cause radio waves of LF to HF to be reflected back to Earth. This propagation is known as "Skip". VHF UHF and Microwaves are significantly less likely to be affected by the ionisation layers.

VHF radio can have a non linear path if subjected to charged plasma such as caused by cosmic radiation such as the Northern or southern aurora borealis.

UHF and microwaves can be subject to "Ducting" where the radio signal will bounce between charged cloud layers.

All radio waves can be scattered by an object which reflects. An example of this is meteor scatter or moon bounce (Also known as EME earth moon earth).

These exotic modes of radio propogation use objects to scatter the radio signal. In this case either meteor showers lilke the Persids which occurs every year or the surface of the moon. These modes are generally only used by Amatuer radio enthusiasts.
