Blocking a radio wave might be accomplished with any conductive metal. Aluminum foil would be better than copper because it is widely available, is far, far cheaper and is more easily formed. But it may be difficult to "block" radio interference. Completely covering one's house with foil will invite ridicule if the foil is not hidden. The best approach to an interference problem is to locate the source. And this may take some doing. When it is found, contact the individual who is there (at the source) and attempt to enlist his aid in curtailing the problem. Think this through fully, and get some technical input. The FCC can help in a limited way. They will tell most people to make a courteous call or visit to the individual who is doing whatever he is doing to create the interference and ask for help fixing the problem so they don't have to try to allocate their (few) resources directly. The FCC has jurisdiction over the noise, but they don't have fifty guys with electrical engineering degrees sitting around drinking coffee waiting for a call. Make no mistake. It is the FCC's job to police the electromagnetic (em) spectrum from DC to daylight. But you have some homework to do. Got a local shortwave or ham (amateur) radio club in the area? They're generally pretty good about helping. You need to find the source. Filter affected equipment. Maybe you prefer to experiment by just taping strips of foil up if you want to. Fold them together along their length to make an em proof seam. See what happens. Good luck. Hit the FCC web site and check for regulations on interference. A link is provided.

Because radio waves can pass freely through earths atmosphere what are useful under most weather conditions?
radio telescopes
Disadvantages of electromagnetic waves?
Gamma rays can kill good bacteria as well as bad bacteria
How does a small piece of copper wire act as an antenna?
A small piece of copper wire acts as an antenna because of the nature of the copper and the way it reacts to the radio (electromagnetic or EM) signal that it is "feeling" as it is sitting there. An EM wave is a moving electromagnetic wave, and it "sweeps" everything in its path of travel. Some things don't react well to it, and others, like our copper wire, "feel" it with ease. The moving electromagnetic field sweeps the little copper wire and induces a voltage in it that is a "just like" the signal that is making the wire react, except that the voltage is much smaller. This tiny signal can be picked up by the electronics in the "front end" of the receiver to which the wire is attached, and it can be amplified and then demodulated to discover what is "on" the signal. If you have, say, a TV with a type "F" connector in the back (for coaxial cable) and you stick a short piece of thin copper wire in the center of the connector, it will act as an antenna and you will be able to pick up local signals (though the signal quality may not be very good). It's a simple and easy way to check the operation of a TV if you don't have any other means available. Just be careful as regards what you are doing, and don't use too large a wire.
What type of wave has the longest wavelength?
Radio waves are amongst the shortest. Gamma and X rays are shorter. The long wave lengths are at the other end of the electromagnetic spectrum. These are called 'infra red,
What is the nationwide network of radio stations broadcasting continuous weather information from the national weather service called?
NOAA Weather Radio
What is world band radio?
Shortwave.
What has the author Lothar Wiesner written?
Lothar Wiesner has written: 'Telegraph and data transmission over shortwave radio links' -- subject(s): Radio, Short wave, Shortwave radio
Are shortwave radio receivers obsolete?
No, not at all. Shortwave listening is a very popular hobby. You can buy ready-made or build-it-yourself shortwave radios. However, as a lifelong shortwave listener, there is, admittedly, less to listen to on shortwave today that formerly.
When was the shortwave radio invented?
I was invented in 1896 to 1922.
What has the author Norman Fallon written?
Norman Fallon has written: 'Shortwave listener's handbook' -- subject(s): Receivers and reception, Shortwave radio
Where can I find information about portable shortwave radio?
Good places to start with would be Radio Shack, Amazon, and places like that. Read the reviews on the different types of portable shortwave radios to find the best one.
Which type of electromagnetic wave would reflect from the ionosphere?
shortwave radio band
Can Hawaii radio 105.1 be heard on a shortwave radio in California?
No - they're on entirely different wavelengths. 105.1 is VHF radio, which penetrates through the ionosphere, and creates a line-of-sight limitation. Shortwave receives Medium- and High Frequency transmissions from 1.8 to 30 MHz - well below the range of VHF radio.
How can you say interference in a sentence?
There was interference with the radio signal.
Portions of the atmosphere used to bounce shortwave radio signals around the world?
Ionosphere
Is the Super Bowl broadcast on HF radio?
Yes, on shortwave or HF radio (they are the same) the super bowl will be broad cast from multiple locations. It can be found at this link http://mt-shortwave.blogspot.com/2008/02/superbowl-xlii-by-shortwave-radio.html
Part of atmosphere used to bounce shortwave radio waves?
Radio waves bounce off of the ionosphere and return back to Earth.
