Try turning the volume knob up!
Or move it closer to your ear.
Increase the volume.

Could be broke, or might just be a Hyundai radio. Check antenna, and cable from antenna to radio.
Your car radio might not turn on after replacing the fuse because the fuse has blown again or because there is exposed wiring. When wires are worn or exposed, they will often cause a fuse to blow out. You might also need to reset the vehicle's computer by unplugging the battery cables for several minutes.
Could be a wire crossing in the speakers, the radio itself might be bad. Does it do it all the time? Speakers might be blown. Or, your antenna lead is not plugged into the rear of the radio. Is it radio static, or does it have static on cd/tape as well?
1) The fact that you turned the volume up.2) A change in the signal emitted by the radio station. 3) The conditions for listening improved; for some reason, there is less interference.
Increase the volume.
Sure. Radio waves, of the right wavelength(microwaves) and intensity will register as heat on the skin, and will eventually cause burns and hurt.
u might have blowed the transmitter

The increase in current (assuming resistance is the same and increase in voltage will lead to an increase in current) will fry your portable radio.
Intensity of sound is dealt as volume in case of radio sets. Intensity is directly proportional to the square of amplitude. So as volume is turned down, intensity is reduced and so the amplitude is decreased.
Radio waves do not cause lightning. Lightning is a natural electrostatic discharge caused by the buildup of electric charge in the atmosphere. While radio waves can interact with lightning strikes and create static interference, they do not directly cause the phenomenon.
The antenna wouldn't cause it to short out, that just helps it receive the signals to play music on the radio... How old is the radio... if it is factory from 91 then it might of been its time to go... i have a radio from a 90 Dodge Caravan, same as whats in your Dodge Spirit cause they carry the same radio and it short out on its own where the numbers and stuff wont light up but will still play music... I took the radio out of my 92 Dodge Spirit and put it in the van (since the trans went out in the 92 Spirit) and it works great... it might of just went out because it was ready to go.
Radio controlled. If you were to use infrared, the orientation of the helicopter might cause a loss of connectivity, resulting in a loss of control.

The question is too vague for an answer. It depends on the intensity of the radio wave source.
