Where can one purchase a personal DAB radio?
One can purchase a personal DAB radio in many different places. Some places where one can buy it are Argos, Amazon, eBay, Tesco, Pure and Harvey Norman.
What is the frequency limit which can transmit without license?
There are several narrow slices of license-free radio spectrum. The easiest way for us
to both answer and evade your question at the same time is to say that any radio
equipment you can buy and legally operate without a license will be built in such a
way as to have its operating frequency limited to the legally permitted band.
Plus ... here's a little-known fact that most owners of such equipment never suspect ...
those frequencies are clearly identified and plainly written right out in the open, in
the instruction manual that comes with the equipment !
If you're unlicensed, then it's never legal to transmit with equipment that you've built
on your own.
What causes radio and dome lights and door buzzer to stop working?
A malfunction of a group of devices like that can be the result of one or more failed
fuses, or a loose wire-harness connector, or a wire harness that got pinched so that
a few wires in it broke.
What is the advantage of AM radio?
The advantage of an AM radio is that the signal it gives off is more powerful than PM and travels further and can be used in any place in the world.
What is the energy transformation in a speaker connected to a radio?
Electrical energy is used to vibrate a diaphragm. The mechanical energy so produced vibrates the air molecules in contact with the diaphragm and these vibrations are then propagated as sound.
I recently put a CD player in my Volvo 940 myself and I'm a 50-yr-old woman so if I can do it so can you. The problem is, I'm trying to remember how I did it. I got the CD player from Crutchfield and they send along a kit and directions of how to install it, in any type of car you specify.
It seems like I had to take out the ashtray underneath the radio first and maybe I got to the screws from there. It's also possible that there were no screws but just clips and it pulled out once you disengage the clips.
I do also remember that in this model car there is some kind of speaker amp under the steering column that also had to be hooked up with the CD player.
******************************************
New ....There is a clip you can reach by removing the buttons out and slide a small screwdriver into the left side (in left button shaft) and into the right side (in right button shaft). These clips have a slot where the screwdriver can be slide in and move sideway towards the shaft. There are no screws to remove and is no need to remove anything else.
There are release clips behind the knobs of the volume and tuning. Just pull of the knobs and the clips will be toward the outside of the radio. pull them in towards the center and then the radio will slide out. The easiest way to pull the hooks is with two straightened coat hangars with little hooks on the end.
after you take out the radio you need to get an amp bypass lead take off the cover under the steering wheel look on top of the steering column and a small box this is you amp pull the lead from the amp leave the amp were it is ,now the lead you have taken off the amp push this into plug found on the long part of the amp bypass lead now you now have still two plugs on the bypass lead push this into the side were the radio is and pull the two plug out were the radio should be now connect the plugs from your new radio to the two plugs on the amp bypass lead fix it all up and enjoy , i have the Volvo 940 SE turbo.
This is amazing. "Wireless" obviously means "without wires", so cellular, broadcast,
and microwave are plainly wireless. But before jumping at an answer, I went online
and looked for a definition of "wire". Here's what I found:
- strand of metal: metal in the form of thin flexible strands, or a single strand of it
- metal strand carrying electric current: a strand of metal, usually copper, that is encased in plastic or another insulating material and is used to carry an electric current
- mesh structure: a mesh made of strands of metal, or a structure made of the mesh, e.g. a fence
Do you see what I see ? Each of those definitions mentions "metal", and that means
that if the conductor is not metal, then it's 'wireless'.
You'd have to include fiber-optic cable in that category then, because the conductor
is glass.
So none of the items on your list is 'not a wireless transmission medium'.
1992 buick leSabre radio antenna wont shut down?
The gears inside are stripped just disconnect the electrical plug on the side of the unit and leave it up.
Why doesn't the dome lights and radio work when the car is running.?
THINK YOU MAY HAVE A BLOWN FUSE. DOME LIGHT AND RADIO ARE NOT ON THE SAME CIRCUIT NORMALLY. NOT SURE WHAT YEARS YOU CAR BUT YOU CAN CHECK THE FUSEBOX ON THE DRIVER KICK PANEL TO SEE IF THERE IS A BLOWN FUSE. IT SHOULD SAY LOCATIONS ON THE COVER AND WHAT AMP IT IS. EASY WAY TO CHECK IS TO PULL IT OUT, THIS WAY YOU'LL KNOW THAT ITS GOOD OR NOT. SOME CAR MAY HAVE FUSE BOX IN THE HOOD FOR THE DOME LIGHT OR IT MAY SAY INTERIOR LAMP. IF THE FUSE ARE GOOD, YOU MAY HAVE A SWITCH PROBLEM WHERE ITS NOT GROUNDED. CHECK THE SWITCH MAKING SURE ITS NOT LOOSE. AS FOR THE RADIO, YOU MAY HAVE A BLOWN FUSE ON THE RADIO HARNESS ITSELF IF ITS AN AFTERMARKET RADIO, CHECK THAT, IF NOT, THE RADIO IS BAD. THE RADIO NEED ONLY THREE SOURCE TO COME ON. 1. CONSTANT 12 VOLTS, 2. IGN 12 VOLTS, AND 3 IS PROPER GROUNDING.
What are the requirements to get a job in radio such as on air host or dj?
There are no set requirements for DJ jobs or for on air personalities. But most of the DJs you hear on the radio have spent lots of time behind the scenes working their way up the radio station ladder. A lot of people with DJ jobs start out with internships at a radio station.
So how do you get an internship? Probably the easiest way is to attend a broadcasting school. Many broadcasting schools have two or one-year programs and internship opportunities. Radio stations want interns who are serious about the industry, so they first go to broadcasting schools first with their internship openings.
An internship is a great first step for those who dream of one day having DJ jobs.
You have another problem.
How do you get code for Acura TL radio?
Acura dealer does it for free but may charge you to get the radio code or serial number you can hold two buttons and get the code and just call the dealer or I think you can do it online too once you have the serial for the radio
Does 60Hz fall into the range of RF waves used by commercial broadcasting?
No. That would be technologically difficult, and very unwise.
-- In order to transmit efficiently, the length of a transmitting antenna must be an appreciable
fraction of a wavelength. The easiest to handle are 1/2-wavelength horizontal wire antennas,
and 1/4-wave or 5/8-wave vertical antennas, including towers. The wavelength at 60 Hz
is 5 million meters, or roughly 3,100 miles.
-- With every utility power line, extension cord, toaster, and baseboard heater in North America
radiating a small signal at 60 Hz, the interference environment for anyone trying to receive
a clear newscast on a pocket portable at 60 Hz would be quite unfavorable.
The lowest frequency used for commercial broadcasting in the Americas is the low end
of the AM dial ... 550,000 Hz, with a wavelength of 545 meters (0.34 mile).
more or less, yes
the Double Din size height at 100mm, wideth & Depth at 100mm, all of the car DVD head unit size is produced according to Din, so every car if have din size, can install the single Din or Double DIN DVD.

What kind of equipment does one need to get started as a short wave radio operator?
Amateur short-wave radio operators (often called "ham radio") must be licensed before they can begin broadcasting. Broadcasting equipment ranges in size and price from a few hundred to several thousands of dollars. Larger "sets" are generally the most expensive and most powerful. RadioShack is actually a very good plae to learn more about all of these devices, as that is why they got started. Listening to shortwave broadcasts can be done very easily and with simple and relatively inexpensive equipment.
