There is no evidence that radio waves can harm you.
However, there are waves inside a mobile phone than canharm you such as microwaves and infrared. This is done by a process called ionisation where cells are split in two or doubled. This causes cancer. Therefore microwaves can be lethal.
But only a small dose is used in mobile phones so there is almost no risk. Also, infrared is well compacked and under control.
What are the disadvantages of two way radios?
There really aren't many advantages, except that once you buy a two way radio, you don't have to pay a monthly bill to be able to communicate. However, the range is so small that you will hardly be able to use it at all like a cell phone.
Big debate over this one. It was either a fella named Marconi, or another fella named Teslsa (not the sucky band named Tesla). Before you can answer "How", you have to decide "who", because the 2 camps believe very different things. Nikkoli Telsa was a genius, with several unique inventions to his name, some of which have been tied to military use (rainmaking). Marconi, on the other hand, was slow to get to the patents office with his invention, which consisted of a device had only a two-circuit system, which some said could not transmit "across a pond." Later Marconi set up long-distance demonstrations, using a Tesla oscillator to transmit the signals across the English Channel. Tesla was embroiled in other problems when Marconi won the Nobel Prize in 1911, Tesla was furious. He sued the Marconi Company for infringement in 1915, but was in no financial condition to litigate a case against a major corporation. It wasn't until 1943
How signal is transmitted to the satellite radio and receive back to earth?
A satellite is like a mirror in the sky. Only instead of reflecting light, it "reflects" radio and television signals. There are receivers and transmitters in the satellite, so what it receives on one frequency (or channel) can be then re-transmitted back to earth on another frequency. Its like sending out signals from a tower that is many miles high to reach out to a bigger area. Only without the tower!

iTunes only provide a link to the PodCast. The PodCasts are hosted on your own site. You then provide the RSS feed URL from your site to Apple for inclusion in the iTunes PodCast directory. (See links below)
Who are the radio announcers for the New York Yankees?
The Yankees use several different television announcers during the season.
Michael Kay, Ken Singleton, Bob Lorenz, David Cone, Paul O'Neill, John Flaherty, Al Leiter and Lou Piniella.
Who are the radio announcers for the Baltimore Orioles?
MASN usually broadcasts the games... they are Bob Carpenter and F.P. Santangelo. F.P. is a former mlb baseball player.
Who are the radio announcers for the Cleveland Browns?
Jim Paschke is the play-by-play announcer and Jon McGlocklin is the analyst.
McGlocklin is also known as "Johnny Mac" from his playing days. He was a member of the inaugural Milwaukee Bucks roster in 1968. His "rainbow jumpers" as described by then-radio announcer Eddie Doucette helped lead the Bucks to the 1971 NBA Championship in just their third yeay.
Where is the old radio in i spy spooky night?
its in the left corner of the windowsill. SIKE! that's the wrong number OH MY GOD????? That's not the right answer.
I'm pretty sure that they travel in parabolas, although honestly I'm tyring to find the same out for myself. The waves themselves are sin/cosine (I always forget) curves.
ADDED.
No, like light, they travel in straight lines, though can be imagined as an infinite number of thin rays fanning out from their source. They are described for analysis as sine curves so their 0-level points start at 0 s. in time, but the cosine curve is the same shape as its companion sine curve, simply displaced by 90º forwards. (Sin 0º = 1, Sin 90º = 1; but Cos 0º = 1, Cos 90º = 0)
What is the frequency used by most commercial radio stations?
In the USA: All commercial AM stations are assigned frequencies in the band 550-1620 KHz, in increments of 10 KHz. All commercial FM stations are assigned frequencies in the band 88-108 MHz, in increments of 100 KHz (0.1 MHz).
With this parameter you define the maximum value of the radio link counter expressed in SACCH blocks. RANGE: 4..64, with step size of 4. A method for preventing a call of a Mobile Station (MS) from being dropped in a mobile communication system

What is difference between modulated wave and carrier wave?
Carrier Wave:
A carrier wave is a high-frequency electromagnetic wave that is used as the "carrier" or the base signal in a modulation process.
It is typically a pure sine wave with a constant frequency and amplitude.
The carrier wave by itself does not carry any information; it serves as a vehicle to carry the information from one location to another.
In AM and FM radio broadcasting, the carrier wave is the primary signal transmitted by the radio station.
Modulated Wave:
A modulated wave is the result of combining the carrier wave with an information signal, such as an audio signal or data.
Modulation is the process of varying the characteristics of the carrier wave (either its amplitude or frequency) in accordance with the information signal.
There are two common types of modulation: Amplitude Modulation (AM) and Frequency Modulation (FM).
In AM, the amplitude of the carrier wave is varied in proportion to the amplitude of the information signal. This variation encodes the information onto the carrier wave.
In FM, the frequency of the carrier wave is varied in proportion to the amplitude of the information signal. This variation encodes the information onto the carrier wave.
The modulated wave contains the information that needs to be transmitted, and it can be demodulated at the receiving end to retrieve the original information.
Why do radio stations repeat the news so often throughout the day?
For more than five decades, radio has played certain songs over and over because those were the songs people requested the most. Radio stations with a "top 40" format (the 40 top selling hits in the country) were designed to be almost like a jukebox, except they have personalities called disc jockeys who talk to you and also play the songs. Stations repeat the most popular songs in what is called a "heavy rotation"-- that is, the #1 song may repeat every hour and ten minutes, because that song is the one the most people are requesting and buying. To you and me, the repetition might seem boring, but people tune in at different times, and when they do, they want to hear their favorite song.
Stations are always trying to get the most listeners, because the size of the audience determines how much money the station can charge advertisers for commercials. (Like them or not, commercials pay for the operation of most stations.) The good news is that not every station plays the same songs over and over-- there are a number of different radio formats, and each has its own version of rotation-- for example, in album rock and classic rock, stations will repeat an important song every two or three days; other songs might be repeated once a week, or even once a month. How often songs get repeated is determined by the station's format, and how many songs are on their official playlist. Top-40 and hit music stations tend to have smaller playlists, while jazz and classical and album rock tend to have larger playlists.

1999 neon new starter just clicks?
If you have already replaced the battery, then you have a few other things to look at.
I would start with the wires, making sure you have a good connection and then work your way to the starter. The clicking is usually a result of the starter not getting enough current to crank the engine.
