There are at least 50 different possible sources of perceived interference to an FM radio.
Most likely is electrical noise from a nearby motor, fluorescent light fixture, or light dimmer.
That's my opinion; I could be wrong.
It could be to filter out outside interference from getting out or in. Radio equipment needs good filtering in the supply.
In magnetic circuits, such as occur in transformers and motors, the flux density is inversely proportional to the frequency, so a drop in frequency could cause overheating through excessive flux density.
AM stands for Amplitude Modulation. In theory, amplitude modulation could be applied to a radio signal on any frequency but the AM band on most domestic radios stretches from 530 to 1700KHz.
It is not as well known as it should be, but some outlets where one can purchase a frequency generator would include internet sites, hardware stores, or local specialty stores.
It depends on the type of interference, but most shielded cables are used in a copper cable setup. You could also use fiber optic cable if concerned about electrical devices but it might prove too expensive.

High frequency sound waves can shatter glass if powerful enough. This happens because the glass vibrates at the same frequency as the sound waves on the outer surface of the glass, but at lower frequencies inside the glass. This causes interference in the waveforms moving through the glass, which stress the glass, causing it to break. This is a different effect than when a single sharp sound, such as an explosion, pushes the glass beyond its breaking point.
Could be interference. Wireless G routers use 2.4 Ghz, some wireless phones also use that frequency. Could be interference with another router, too. Could be weak signal, or if there's metal in close proximity, especially a chain link fence.
Intentional interference with a broadcast. It could be another transmitter on the same frequency or a device that generates other electrical pulses that cause bad reception in the vicinity.
it is basically when you intentionally causing a party to breach a contract. For example, if someone had a contract to sell 1000 books to someone and you burned the books, that is malicious interference. This is just an example, you probably wouldn't be charged with malicious interference because it would be a criminal act as well. However, if the interference was only a civil offense you could be sued and taken to civil court.
yes you can. the plugin is on top
Radio frequency interference (rfi) is simply either man-made or natural sources that interact with radio waves. A natural source - is the crackle you hear from your radio when there's a lightning storm between you and the transmitter. A man-made source - could be something like hearing a taxi-cab radio over a 'normal' radio program.
Yes, if the sound waves were generated with a frequency that matched the natural frequency of the ice, resonance would occur. If the amplitude i.e. the sound was loud enough, and the frequencies were matched, the ice could vibrate with enough force causing it to shatter.
All electronic devices emit stray interference signals, and some emit powerful interference. Aircraft use complex electronic systems, and if 200 passengers are using electronic devices, the interference is very powerful and covers a very wide frequency range. Not only that, but all the frequencies emitted mix with each other to produce new frequencies. This could make the plane do strange things like diving into the ground. That could spoil your whole day.
i would say vissed.board if you could but you need a download plugin
With either a digital frequency meter or an oscilloscope.
Loosening the string will LOWER the frequency, tightening it will RAISE the frequency.
