Who is voice is being used in the Kaiser Permante radio ad?
According to http://www.voiceoverresourceguide.com/la/vorgspeak/article_celebanswers.html, the voice is Allison Janney, of West Wing fame.
November 2, 1920 was the first time the radio went to the public.
----------------------
Difficult to answer...it happened in small stages.
Marconi in very late 19th century achieved the first transmission and reception. I believe he used a spark-gap transmitter and a coherer receiver.
Then Lee DeForest invented the triode tube (1920), and the superhet became possible.
Then directly heated tubes appeared, and portable radios became possible. (about 1950)
Then the transistor was invented, also in several stages, becoming practical about 1965.
What is the most listened to radio morning show?
A STATE OF TRANCE. Its a radio show hosted by the number 1 DJ in the world - Armin Van Buuren with 30 million listeners every week tuning in across the globe!
What is the music used in BBC radio 4 'this sceptred isle'?
Prelude to the Suite for Strings by Frank Bridge.
Because it's not licensed to transmit on the frequency it uses, or to radiate radio
signal to the population centers where it does that. Other than that, it's a fine and
noble service to society.
How do you enter the code on a radio of a 1982 Mercedes 300 SD turbo desil?
There is no code. Take it by the dealer they have a tool to reset the radio.
How do you remove a Toyota Sequoia radio?
Easy job on the 2002. Turn the two center air vents down and look inside above them. You will see a screw in each. Remove the screws and the face plate will come off. The radio is then bolted into the dash and can easily be removes. I hope no car radio theives are reading this!
Why does your radio go to static when you turn the ceiling light on?
The small spark created by the contact of the switch created radio frequency waves that happen to included the frequency of your radio.
What is the code for the radio in a mercedez Benz C 220?
How to get the 1995 c 220 Mercedes radio code? i just open the Battery and my radio code reset, i don't know the code
How long in meters is a typical radio wave with a frequency of 88 megahertz?
The length of a wave is denoted by its wavelength, which is found by dividing the speed of light, or c, (3 x 108 m/s) by the frequency (88 x 106 Hz). The answer is 3.4 meters.
I need Radio code for my ford fairmont au2 2000?
You will need to get the code from your nearest Ford dealer - for that, you need the Vehicle Identification Number (VIN) and the engine number! Go to the parts department desk at your dealer and ask for the radio code - the salesman will ask for the VIN - supply that and they will look it up on the computer and write it down for you!
What are the lyrics to White Flag?
White Flag lyrics I know you think that I shouldn't still love you Or tell you that But if I didn't say it, well I'd still have felt it Where's the sense in that? I promise I'm not trying to make your life harder Or return to where we were But I will go down with this ship And I won't put my hands up and surrender There will be no white flag above my door I'm in love and always will be I know I left too much mess and destruction To come back again And I caused nothing but trouble I understand if you can't talk to me again And if you live by the rules of it's over Then I'm sure that that makes sense But I will go down with this ship And I won't put my hands up and surrender There will be no white flag above my door I'm in love and always will be And when we meet, which I'm sure we will All that was there will be there still I'll let it pass and hold my tongue And you will think that I've moved on I will go down with this ship And I won't put my hands up and surrender There will be no white flag above my door I'm in love and always will be I will go down with this ship And I won't put my hands up and surrender There will be no white flag above my door I'm in love and always will be I will go down with this ship And I won't put my hands up and surrender There will be no white flag above my door I'm in love and always will be
Who is the largest radio station owner in the US?
Except for 'public' stations, every radio station is owned by an individual or a business
group. The purpose of owning and operating a radio station is to make money, by selling
a product to a customer.
The seller is the owner of the station. The customer is the advertiser whose commercial
announcements are aired on the radio. You, or at least your ears, are the product sold.
The music, news, sports, traffic, weather, and chatter are the bait that keeps your ears
there to hear the commercials.
There's nothing wrong with this. It's the American way. But you should be aware of it
and keep it in mind.
Check for a little white sticker on the left side of the Glove Box it should be a 4 digit code. The two other spots are under the fuse box and under the passenger seat. If you have no luck you'll have to pull out the stereo and get the serial number off the unit and give it to a Acura Service guy he can look it up and tell you. Good Luck.
Are you related to anyone famous?
The only way to know if you are related to someone famous is:
- be told that by a parent or other relative, and have reason to believe they are correct, or
- see it in an existing Family Tree, and have reason to think it is correct, or
- research your own family history with care and, using valid records, show that you are related to someone famous.
Role of radio in disaster management?
Many disasters involve the crippling or destruction of normal communications methods:
- Telephone (especially cellphone) networks may be overloaded.
- Electrical power may be unavailable (especially at a disaster site).
Radios and radio systems that are portable and battery (or generator) powered can avoid the above problems.
On the radio what is wild 94.9 number?
As of the middle of July 2011, there are 71 FM stations licensed to operate
on 94.9 in the US.
Since you didn't mention where you're located, we have no way of knowing
which one you're listening to,
How do you get the radio card?
you get the radio card in the radio tower in goldenrod city,talk to the third lady on the first floor and she ask for you some answers and at the end of the questionaire the lady gives you the radio card.
A radio controlled car or R/C car is a powered (electric or gas) model car driven by a radio control system. Inputs from joysticks (or a wheel and a trigger) on a transmitter are sent to the car's onboard receiver. Radio controlled cars can range from simple "stop and go" cars to competitive racing models, which feature all the complexity and adjustability of a full sized racing vehicle.
How do AM FM radio antennas work?
In order to understand antennas it is helpful to understand electricity and it's effect on metals, so for a comprehensive understanding you should first educate yourself on that subject. However, if you are just curious and would like to have a basic knowledge then consider the following analogy. When you throw a beach ball into a calm swimming pool, you will see waves go out in all directions from the beach ball. The waves will proceed across the pool until they encounter the interference of the edges of the pool. The height of the waves depends both on the size of the beach ball you throw and how much power you put into that throw. Antennas work in the same way. When electricity is "thrown" into the metal of an antenna, the metal reacts to the electricity at an atomic level in the form of a wave. This wave, just like the beach ball wave in the swimming pool, radiates outward from the point where the electricity enters the antenna. Now, because antennas are working with radio waves and not water waves, the waves in the metal of the antenna actually produce waves in the air touching the antenna. The waves also continue outward through the air until they encounter interference which is why you will have difficulty receiving a radio signal deep inside a building. The structure of the building is stopping the radio waves in the air from getting to you, just like the edge of the pool prevents the water waves from getting to you as you sit in your pool side lounger.
How do you install a radio for a 1993 Nissan nx?
Here is a great website to guide you through your 1994 Nissan Stereo installation it even has step-by-step pictures: http://www.installdr.com/InstallDocs/Nissan/PDF/647033.pdf Remember you probably have to get a diversity antenna. I didn't realize that until I had everything installed and tried to turn the stereo on and nothing happened. Even though I had the power hooked up nothing came on. I had to make a quick drive to the Car Stereo Store and get the diversity antenna, then everything worked fine.
What are diffrence between AM radio waves and FM radio waves?
AM stands for "Amplitude Modulation". The sound signal you hear is transmitted by modifying the amplitude of the carrier frequency.
FM stands for "Frequency Modulation". The sound signal you hear is transmitted by modifying the carrier frequency itself.
AM uses a 5Khz bandwidth with additional space to allow for signal separation avoiding interference between stations.
FM requires a wider bandwidth.
AM has lower sound quality and is subject to static from weather conditions and adjacent frequency radio transmissions.
FM has wider bandwidth per channel, due to the better ability to separate noise in the FM bandwidth.
AM has a longer range than FM and with the correct conditions can bounce a signal off the ionosphere allowing for longer range possibly causing interference with far away radio stations on the same frequency.
FM signals line of site only and will drop of after about 50 miles from the station as the earth curves away. To compensate for this, broadcasting stations use high transmission antennas.
How do electromagnets work in radio?
For a given load, the higher the supply voltage, the lower the load current. So, in order to avoid enormous voltage drops along the lines, high energy losses, and the need for conductors with large cross-sectional areas, transmission voltages must be very high. This is achieved using transformers. At the consumer end of the transmission/distribution system, transformers are needed to reduce the transmission/distribution voltages to safe levels required at homes and commercial/industrial loads.

Correct, but the question was "how", not "why".
An ordinary transformer consists of two separate coils of wire, the 'Primary' and 'Secondary' windings, on a 'Core' consisting of a stack of soft iron sheets lacquered to insulate them electrically from each other, to minimise internal losses.
As the input alternating current passes through the primary winding, it induces an alternating magnetic field in the core. In turn, that induces an alternating current in the secondary winding.
The number of turns in the coils matters: the ratio between input and output voltages, hence between their currents for the same power, is that of the turns; and the Volts and Amps ratios are inverted with respect to each other.
Hence 230V at 1A in a primary winding of 1000 turns will theoretically produce an output voltage & current of 23V at 10A in a 100 turns secondary - assuming the transformer is designed for that 230 Watts (which = Volts X Amps) power rating.
There are no direct electrical connections between the windings and the core. The link is entirely magnetic, but the induction will only work with alternating current. Having said that, there IS a type of transformer whose windings are connected electrically, but the principles are similar.
How can radio sustain culture?
IN THIS ASSIGNMENT I AM GOING TO EXPLAIN HOW RADIO CAN SUSTAIN CULTURE.FIRST AM GOING TO DEFINE WHAT IS CULTURE AND RADIO.culture is
- a particular society at a particular time and place; "early Mayan civilization"
- the tastes in art and manners that are favored by a social group
- acculturation: all the knowledge and values shared by a society
- (biology) the growing of microorganisms in a nutrient medium (such as gelatin or agar); "the culture of cells in a Petri dish"
- polish: a highly developed state of perfection; having a flawless or impeccable quality; "they performed with great polish"; "I admired the exquisite refinement of his prose"; "almost an inspiration which gives to all work that finish which is almost art"--Joseph Conrad
- the attitudes and behavior that are characteristic of a particular social group or organization; "the developing drug culture"; "the reason that the agency is doomed to inaction has something to do with the FBI culture"
- grow in a special preparation; "the biologist grows microorganisms"
- the raising of plants or animals; "the culture of oysters" THEN RADIO IS
- medium for communication
- radio receiver: an electronic receiver that detects and demodulates and amplifies transmitted signals
- transmit messages via radio waves; "he radioed for help"
- a communication system based on broadcasting electromagnetic waves
- indicating radiation or radioactivity; "radiochemistry" THE REST YOU CAN EXPLAIN IN YOUR OWN KNOWLEDGE. from university of limpopo(turfloop campus)MDST 102.
