Where can you find the radio wiring diagram for a 1994 Dodge Dakota pickup?
you don't neccesarily need a wiring diagram if the stock plug is still there. when you buy a wiring kit for that specific vehicle the wires will be color coded to match up to the new radio (red to red, yellow to yellow etc). you just connect the wiring harness for your truck to the wiring harness for your deck and plug 'em in. if it's not there...you need a 12v constant, 12v switched, ground, and +/- spekaer wires for each set of speakers.

What are the differences in broadcast and hobby radio?
in tv boardcasting we can see the picture as well as video that help us to know more about any happenings while in radio only audio is displayed which can't immediately give more information ,but its also very important.
What are some natural sources of radio waves?
We generally think of radio waves (radio electromagnetic radiation) as those frequencies of electromagnetic (EM) radiation that fall within a band of frequencies below those of light. These include microwave bands, on which satellites communicate and cell phone operate, as well as the familiar microwave oven. Radar also operates in this band. Below that we find television signals, as well as some two-way radio signals. Other forms of communications radio signals (like amateur or "ham" radio) as well as broadcast radio operate below the television bands.
By considering the types of equipment mentioned above, it is possible to make a list of some sources of radio electromagnetic radiation.
Do radio waves have the shortest wavelength?
First of all, your question is not worded all that well. When we speak of a wave, in this case an electromagnetic one (as opposed to one made of water perhaps), we tend to describe them quantitatively with certain numbers. One may speak of the frequency of the wave (measured in Hertz), the energy of a wave (in joules), or, in your case, the wavelength of a wave (in metres).
The electromagnetic spectrum is usually taught to span from radio waves (waves with relatively large wavelengths and low frequencies) to gamma rays (waves with relatively small wavelenths and very high frequencies). The misunderstanding you seem to have is that the electromagnetic spectrum stops at radio waves. It does not.
In theory, the electromagnetic spectrum is infinite and continuous. That is to say, there is no limit to how large a wavelength can be nor how small one can be. The electromagnetic spectrum susually stops at radio waves (with a typical wavelength ranging from 1 to 10 metres) because waves longer than these lose their practicality. In theory, they exist, but they simply are not as important to us than their shorter cousins!!!
Just as a side note, "long waves" are said to have a wavelength of around order 10^3 metres (or just around the order of a kilometre). Theoretically, I can imagine it possible to have a wave with a wavelength as long as the universe itself! Of course, as I mentioned earlier, such waves are of little practical value to us. As a result, yes it does have the "longest" waves.
What is a device that sends out radio waves?
Intentionally: Radio Transmitters for Walkie-Talkies, TV and Radio broadcasts etc.
Inadvertantly: Alarm Systems, Florescent Lightbulbs, some motors
Natuarally: Outer space and water
(this is not nearly a complete list)
How to Remove radio from Nissan almera?
Assuming it is similar to my 1990:
A: Identify the trim surrounding the radio. It extends from the radio, above the steering column, and has buttons like hazards and rear defrost on it. This trim has a number of screws attached on its underside in little recessed screw holes.
B: Remove all the screws. Once you get all the screws to the left of the center console, there are two screws also in the little trim divider halfway down the center of the stereo.
C: You also need to open the ash tray and get the two screws from above it. You should now have all the screws removed.
D: Pull up, and outwards on the trim to remove. You will need to clear the steering column with an upwards motion. Careful not to pull too far, there are several wires attached to the back of the trim that you do not want to rip loose.
E: With the trim removed there are only four screws on the two sides of the stereo. Remove these screws and you should be able to pull the head unit assembly out of the dash. From here you will need to unplug the wiring harness and antenna cable and power cable.
Hopefully that is of some help. And hopefully you aren't the schmuck who unsucessfully tried to steal my stereo a few months ago. That would be ironic
What part of the radio vibrates?
Radio waves vibrate the impedqnce or ether of free space. The space or ether impedance is the ratio of the magnetic charge W-500 e-18 webers(volt seconds) and the electric charge C=4/3 e-18 Coulombs. z=W/C= 500x3/4=375 Ohms! The vibratioon of the ether propagates the electric wave.
Answering your question, no. As of 18:40 MTZ on the ninth day of July in the year 2013, Bruno Mars is still alive and in presumably good health. Rumors of his alleged death in a car crash were nothing more than a hoax - one more among a series of celebrity death hoaxes which have been occurring recently.
How do you remove a radio from a 2001 Honda Accord?
First disconnet your battery.Carefully pry out the clock out of the middle and there is a screw back there you need to take out ,than two more screw at the bottom of the center cover. Once u take the screws out carefully pull the console out and disconnect the two ac connectors(I had to use a flat-head to get leaverage to loosen), but once that's done there are four more screws holding the radio in the frame. And just do reverse to reinstall
Do all mp3 players have FM radio?
I have been looking on my ipod nano and i can not find how to get the radio if you know that it does not have a radio will you please reply! Thank you
iPod nanos do have radio. You can usually find it on the main menu.
You already have a car radio how do you get satellite radio?
I think it means you can buy a satellite radio receiver, and your stereo will accept it's input without modification.
Where do you find the code for the radio in your Renault megane scenic?
Radio Code you can find in the service book. Search for the symbols C.A.R and four digits near must be a code.
Guglielmo Marconi (Marchese Guglielmo Marconi), an Italian inventor, proved the feasibility of radio communication. He sent and received his first radio signal in Italy in 1895. By 1899, he flashed the first wireless signal across the English Channel, and two years later received the letter "S", telegraphed from England to Newfoundland. This was the first successful trans-Atlantic radiotelegraph. Wikipedia has a good article on this Nobel Prize winner, and a link is provided.
A piece of apparatus that makes electromagnetic waves at radio frequencies (above 30Hz to less than 300GHz). Almost always this stream of waves is made to carry information of some kind in some way, a process known as modulation. The information could be just sound, or television, or telephone conversations, and or various other things. The simplest forms of modulation vary the radio waves' amplitude or frequency is step with the information that must be carried.
Can you use your satellite radio antenna for your gps?
No, you can not use any satellite radio to connect to Sirius. The hardware for each (XM or Sirius) is designed specifically for one or the other. For Sirius, there is a code on the back of the radio that they need to activate the service. It is specific only to Sirius equipment.
How does a crystal radio work?
This contributor finds it easiest to understand the following explanation.
Fasten your seat-belt; it may be a bumpy ride:
The basic principle to keep in mind is this:
When you pass more than one frequency through any non-linear device, the frequencies
get "mixed". What comes out the other end is the original frequencies PLUS the sum-
frequency and the difference-frequency of every possible combination of the original ones.
Remember this.
A non-linear device can be anything that conducts current better in one direction
than it does in the other direction. Like a semiconductor diode. Or a sharp-pointed
wire touching some varieties of naturally-occuring minerals, which are called "crystals"
when they're used in simple hobby radio kits.
Start at the radio transmitter:
-- The transmitter generates a "carrier" wave, at the frequency where it'll show up
on your radio dial.
-- The carrier wave and the voice or music waves are passed through some non-linear
device, where the frequencies get mixed.
-- What comes out is the (carrier frequency alone), (music frequency alone), sum of the
(carrier + music) frequencies, difference of the (carrier - music) frequencies.
-- The transmitter sends out the narrow cluster of (carrier alone), (carrier + music), and
(carrier - music) frequencies. The (music frequency alone) is filtered out and discarded.
Now go to the crystal radio:
-- The wire antenna catches some of the radio waves as they fly by, and conducts them
down to the "radio" set.
-- Flowing down the wire are separate signals at different frequencies. There
are the (carrier frequency alone), the sum (carrier + music) frequency, and the
difference (carrier - music) frequency.
-- All of them are sent through the "crystal", where the frequencies mix. The original
frequencies come out, along with the sum and difference of each pair.
-- Out from the crystal come these frequencies:
The originals: (carrier alone), (carrier + music), (carrier - music)
The sums: (carrier + carrier + music), (carrier + carrier - music), (2 x carrier)
The differences:
(carrier - carrier - music) = -music
(carrier - carrier + music) = music <==== ! ! !
(carrier + music - carrier + music) = 2 x music
Almost hidden in this pile of many electrical signals is one that's a copy of the original
music signal ... exactly what came from the microphone back at the studio, and got
mixed with the carrier for transmission.
All of the other signals that come out of the crystal are filtered out and discarded,
and just the "music" signal alone goes to the headphones ... "for your listening
and dancing pleasure", as they used to say in the days when the crystal radio was
about the best that everyone had.
Why Did The Grand Ole Opry get started?
Country music has basically been the music of rural America. However, in the 1920's, through the use of radio, country music was getting a bigger audience in towns and big cities across the country as well.
The creation of the Grand Ole Opry is credited to George D. Hay, who was an inventor and promoter. He became a member of the Country Music Hall of Fame in 1966.
The radio show was created to give people all across the country the chance to hear live performances by those artists who recorded the hits that they heard on the radio. The popularity of the Grand Ole Opry spread like wild fire. Soon, the Grand Ole Opry would become known as one of the "Great Institutions of Country Music."
The Grand Ole Opry will celebrate it's 83rd birthday, in October 2010. It holds the record for the longest radio show in history, and I don't think that record is ever gonna be broken!
What kind of waves are gamma rays and radio waves?
Radio waves are electromagnetic waves and are a part of the electromagnetic spectrum. Other electromagnetic waves in the electromagnetic spectrum are microwaves, visible light, infrared, ultraviolet, x-rays, and gamma rays
Where is the fuse for the radio on Renault clio?
I have the same problem, sounds like there is one fuse for both the cigarette lighter and the radio. If this has blown, the radio will run from the battery power supply rather than the ignition, therefore only giving you 20 minutes before it automatically turns off. When I get chance im going to try changing the fuse and see if it works.

How do long wave radio signals get back to an aerial?
As long as a radio signal is shooting from one place to another through space, it's
a wave of electromagnetic fields. Once it hits an electrical conductor ... like a piece
of wire that happens to be part of an antenna (aerial) ... the electromagnetic fields
set up a small electric current in the conductor, and the signal has been "captured".
That small electric current runs directly into electronic equipment that's used to make
the current stronger, pick out the one single frequency from all the hundreds or
thousands of separate signals that have set up currents in the antenna as they
passed by, then make that one stronger again, and eventually strip the information
from it, and use the information to reconstruct the sound of a song, the voice of
a newscaster or a cellphone caller, a TV picture, the data off of the Wifi in your
house, or the data from ten different satellites for the GPS unit on your dashboard.
One of the primary goals of the art and science of antenna design is to squeeze
the maximum antenna current out of that incredibly weak electromagnetic signal
as it flies by.
