What else can I help you with?
What radio operates between the frequencies of 3000 kHz and 30 MHz?
GPS Lots of things use these frequencies. There is an amateur radio bad around 1250. Cell phones are around 1800 (and even higher). Microwave ovens are around 2450. WiFi is slightly higher. Bluetooth is in there, and a lot of point-to-point microwave radio links which are used by the phone company to get signals 20 miles or more without wires. Micro Links are also used by radio and television stations to get the signals from their studios to their transmitters (STL). There could even be certain radar, radiotelescope, and satellite frequencies in that band but I am not sure of that.
What do broadcasting stations use to send their signals around the world?
Broadcasting stations use television satellites to send their signals around the world.
Do radio waves get through earth's atmosphere?
No, radio signals can come from broadcasting towers and can be received by radios, without the need for satellites; indeed, radio broadcasting originated long before the first satellite was launched.
Which radio signals past through metal metal vhf lf FM or am or phase modulation?
No radio signals pass through metal. But depending on their wavelength, they may diffract more or less efficiently around the edges and be detectable on the other side.
What is ham radio?
Ham radio operators use two-way radio stations from their homes, cars, boats and outdoors to make hundreds of friends around town and around the world. They communicate with each other using voice, computers, and Morse code. Some hams bounce their signals off the upper regions of the atmosphere, so they can talk with hams on the other side of the world. Other hams use satellites. Many use hand-held radios that fit in their pockets.
Which layer in the earth's atmosphere helps in long distance communication?
The ionosphere, a layer in the Earth's atmosphere that begins around 30 miles above the surface, aids in long-distance communication by reflecting radio waves back to Earth. This allows radio signals to be transmitted over long distances, such as for shortwave radio broadcasts or communication with satellites.
What is the difference between am and shortwave?
AM stands for amplitude modulation (the kind used in the am broadcast band and also on the shortwave bands).The shortwave bands begin just a little higher than the top of the am broadcast band and go up to 30000 KHz. The am broadcast band is from 530 to 1700 KHz and shortwave broadcast bands begin about 2000 KHz. The programming on shortwave stations is many types such as cultural,news,science,and just about anything about the country which the station is broadcasting from.Between the shortwave broadcast bands you can also hear amateur radio operators,military,utility stations,radio beacons,pirate broadcasters,radio telephone,aircraft, radio teletype,and lots more.The higher bands (above about 9000KHz) are daytime bands because the signals there propagate around the world in the daytime and the lower bands below about 9000 KHz are nighttime bands and you listen there from about sunset to sunrise.I could go on forever but that is probably about as you want to know about it unless you have ever listened, once you have experienced shortwave listening when conditions are right, you will be hooked on a great hobby.

Which sentence an example of informal English?
its hard to believe but a shortwave radio can take you around the world for a song
Why a satellite is necessary to send tv singals?
It is not necessary. TV signals can be transmitted many different ways. However, they are used to transmit over the horizon of the Earth. Standard transmissions from the surface of the Earth do not bend around, unless you are using shortwave technology which does not provide the spectrum necessary for TV.
What do broadcasting stations use to send their signals around the world?
Broadcasting stations use television satellites to send their signals around the world.
10 uses for satillites?
1. They help speed communication around the world. 2. They can get out past the atmosphere so that astronomers can get a better look at the stars, etc. 3. TV signals 4. Navigation systems.
Which outer planet has a rectrograde rotation?
Uranus... interestingly, most of Uranus's atmosphere rotates faster than the interior; the planet's fastest winds blow portions of the atmosphere around the planet in only 14 hours.Uranus.
What is a sentence using atmosphere?
The atmosphere is all around us.
Are fountains at World's Columbian Exposition still around?
No, only portions of the lagoon remain.
All of the gasses around a planet make up their?
Atmosphere.
