Radio
A radio refers to an electronic device that works by receiving radio wave (an electromagnetic wave) that has the capacity to broadcast news, speech, music and other audio through the air.

Purpose for inventing the radio?
The German Physicist Heinrich Hertz was the first to generate electromagnetic
radiation (radio waves) and detect them on the other side of the laboratory.
He did that in 1888, when Benjamin Franklin had been dead for 98 years.
What radio stations carries Michael Savage Radio Show in Arizona?
One of them is KFNX 1100 AM from 7-9pm (they only play 2 hours of his 3 hour show though).
What are function of radio waves?
To transmit. (I couldn't help it. Really.)
A great number of electronic circuits need to send information to a distant place. "Distant" isn't really a hard-and-fast term; it could be an inch away over a piece of hook-up wire, to the next room via your Wi-fi connection, to the next town over FM radio waves, a country on the other side of the ocean via a submarine cable, or to another planet with a dish pumping out megawatts of microwave energy. The system that structures the information in such a way that it can be sent and increases its amplitude to ensure it will get where you need it to go, is the transmitter.
Who wrote the song Stanky leg?
"Stanky Legg" (aka Do Da Stanky Leg) is by the GS Boyz (G-Spot Boyz), a rap group from Arlington, TX.
How do you stop cb radio from over modulation?
Over-modulation is usually the result of setting the transmit-audio level too high,
so the first thing to try is either to turn down the mic-gain or else stop shouting
into the microphone.
The question is a good illustration of why the FCC doesn't allow home-made CB equipment
to be used by unlicensed operators.
What happened to Larry Elder on KABC?
He and KABC agreed to part ways. It sounds like KABC had to make budget cuts and Larry didn't accept the pay cut so he decided to quit.
When was the telegraph system invented?
In 1809, a crude telegraph was invented in Bavaria by Samuel Soemmering. He used 35 wires with gold electrodes in water and at the receiving end 2000 feet the message was read by the amount of gas caused by electrolysis. In 1828, the first telegraph in the USA. was invented by Harrison Dyar who sent electrical sparks through chemically treated paper tape to burn dots and dashes.
How do you take the radio out of a 2000 civic?
I just changed mine, you have to take the screws out of the pieces below the radio so you can get to some more screws which are located on a bracket beneath the radio! The radio will slide out with the bracket attached! Not a 5 minute job!
What is selectivity of a radio receiver?
These are the 3 criteria in choosing a good receiver. Sensitivity refers to the ability of the receiver to receive very weak signal. Selectivity to select the desired frequency and reject the others. lastly, Fidelity to produce good quality of signal without distortion.
Who replaced Phil hartman on the final season of newsradio?
Max Louis (Jon Lovitz) is Bill McNeal's replacement in season five .
Yes, like all electromagnetic radiation can be polarized.
The A. T. & T. Long Lines Microwave tower system doubled its long distance call capacity by using cross polarized microwaves. This system operated from the late 1940s to the early 1990s (when fibre optics superceded it, but many of the towers and horns remain, see the image above showing a transmitting/receiving pair of horns).
Where does radio wave fit into the electromagnetic spectrum?
Here are the ways you use the radio portion of the electromagnetic spectrum
just while you're in your car :
-- listen to the traffic and weather reports
-- listen to music and news
-- use your GPS to find an address
-- get a call on your cellphone
-- talk on your CB
-- open the garage door without getting out of the car in the rain
How do you set the radio clock on a 2004 Hyundai Elantra?
Turn your car on, so that the radio can be turned on and off. Then turn your radio off. After is it off, push the clock button and while holding clock, use seek to change the hour and tune to change the minutes.
Why does a single radio telescope have poorer angular resolution than a large optical telescope?
They are forming a picture based on sound waves arriving from a target in space, not an actual visual picture. They work better for determining what types of radiation is being emitted by the extraterrestrial object and conclusions can be made about it's makeup based on past data collected Check out the link provided for more information. Answer
Resolution on a telescope is determined by the wavelength of the light they use. The smaller the wavelength the better the resolution. The wavelength of radio waves can vary from a couple of metres to several kilometers long, so they do not give a clear image. Also they are forming a picture based on radio waves coming from a target many lightyears away, so there is often a big margin of error.
How come the proffeser on Gulligans Island can make a coconut radio but cant fix a hole in a boat?
Good question! There were plenty of palm trees on the island. The Professor was a bright guy. I guess, the writers wanted to keep the cast on the island for as long as they could! duhh!!bunch of idiots
obviously they werent able 2 build a boat on gilligans island because it would end the series..AND OBVIOUSLY THE CHICKEN CAME B4 THE EGG
Is national public radio left leaning?
NPR tends to have a larger amount of liberal listeners. There have been accusations of a liberal bias against NPR.
What happened to Monique and radio one?
From what I understand, her radio show has been cancelled, and least in the Philadelphia area. I am not sure about other locations. She has also been cancelled in Houston.
I live in Houston and she's still on.
From how far can radios receive a signal?
It depends on six factors:
1. Transmitter power,
2. Transmitting antenna,
3. Receiving antenna,
4. Receiver sensitivity,
5. Frequency and type of operation,
6. Any land or obstacles between the two radios.
The deep space probe that passed by jupiter, neptune and the outer planets was still sending from billions of kilometres away.
A small iPod FM transmitter, such as the ones used to broadcast fro an iPod to a car radio have a range of less than ten metres.
2.4 GHz Wi-Wi can have a range as small as one room (depending on building construction) or hundreds of kilometres with large antennas sited on mountain tops.
Generally? Don't believe sales hype - ask somebody who uses similar equipment, or ask to test the gear yourself under the conditions you expect to use it in.

Another contributor provided a benchmark:
As of December 2010, the Voyager I spacecraft, launched by NASA in September 1977,
is still operating, and communicating with earth by radio, from its position on the 'edge'
of interstellar space, presently about 10.6 billion miles from us.
Can radio waves reflect from surfaces?
Yes, radio wave can reflect off of surfaces. Dish antennas use this property to focus the radio waves to a single point and produce very high directivity.
How do you set the Radio Stations on a Sendai CD789?
Take the radio out. On the back is a red cable and a yellow cable. About 2 inches down are the connectors. undo them and swap them over so that red connects to yellow and yellow connects to red.
YET THE GOVERNMENT HAS NOT FLOATED THE BID FOR JAMNAGAR, POLITICAL PEOPLE ONLY WORK WHEN THEY GET SOMETHING ! KIM JAMNAGAR
What is the longest running radio show?
Music and the Spoken Word the oldest continuous nationwide broadcast in the world, which began July 15, 1929 & continues today.
