How to interfere AM/FM radio waves?

Question

I want to interfere AM/FM radio waves in my house. My sister is listening to friggin disney channel radio and I want to get rid of this stupid music. Where I could find a transmitter that could do that?

Answer 1

You could buy an FM transmitter but that could be expensive.

On the other hand, I have heard of people doing the following to jam FM stations but have never done it myself. I have to tell you that it is illegal to jam radio transmissions. You need to find a 100 MHz oscillator chip. You can probably find one on-line but it will cost some money, not a whole lot, but something. A cheaper way would be to pull one out of an old FM radio. They are usually metallic and have four leads coming out of them. If you can carefully remove it (de-solder or carefully cut with snips) and hook a battery up to the power leads and a long wire up to the oscillator output, you could generate enough RF noise to swamp her radio.

This might work better with a cheaper older part than a newer one.

I suppose something similar could work for AM; you'll need to find an oscillator in the AM band (1 MHz). Of course, AM is susceptible to all kinds of noise. Turning on the washing machine could have the desired effect. So would a blow dryer, but then you would have to listen to the sound of that instead of the radio.

Again, jamming radio transmissions is ILLEGAL.

Answer 2

Expensive prank. You need an AM/FM transmitter a 1-2 watt will do. google for best price. its going to cost about $500. then you simply broadcast on the same frequency with something else, your transmitter will overpower the Disney signal for a few hundred yard radius

actually, water and moisture unquestionably can intervene with RF alerts. I artwork in the RFID and RF fields and there are subjects each and all the time in this regard. Radio alerts, exceptionally in the Gigahertz and above variety may well be stricken by using water, moisture or maybe the water content cloth in a human physique. the undertaking is that those alerts tend to be absorbed by using water. take be conscious in case you have a satellite tv for pc television receiver. in case you dont have an extremely stable satellite tv for pc restoration, you are able to word a sign help and interference for the period of a rain or snow hurricane. it is via the greater desirable moisture in the ambience. You reported cellular telephones. The frequency of cellular telephones is someplace between 800Mhz and 1000Mhz. those frequenceies may well be stricken by using water in the comparable way. The UHF RFID frequencies used in the US are in the community of 900MHz. I even have examined and reported subjects examining them by using or close to human beings or packing containers of drinks. this may well be a real and measurable result on the RF overall performance ranges. The impact of water is greater approximately issues of the RF passing by using it, not a lot merely by using being close to it. maximum RF structures, which includes GPS this is above 1Ghz, works nicely close to water, yet not by using water. Thats why GPS won't artwork under water, yet works super on the floor. Its additionally why submarines would desire to the two communicate making use of extremely low frequencies under water, or deliver an antenna to the floor to apply radio. i think of the end results of being close to the lake at some cases would have greater todo on the subject of the shortcoming of cellular towers or different subjects, and doubtless a severe humidity point, that with the end results of the water in the lake itself.

You probably shouldn't do this, since it is illegal as there are FCC rules that prevent you from transmitting without a license. It might also interfere with your neighbors reception.

It is a lot cheaper to buy your sister some earbuds.
