    Hello

    Does anyone know how to disturb the radio receiver (e.g. the 88-108FM frequency "playing" behind the wall). Sometimes it happens that the radio connected to one socket with the drill is "disturbed" when the drill is operating (apart from the fact that it is effectively jammed).
    Is it possible to permanently disturb the radio with something, e.g. through a 230V socket, similarly to a drill?

    Regards

    Why do you want to disable the receiver? And if the radio is connected to the same socket as the radio, interference from sparking brushes in the engine is possible.

    The problem is not in the goal, but in the method ;) Please give me more specific instructions.

    You can jam the radio with another transmitter. It may be an RF generator operating in this frequency range with a piece of wire (antenna) connected to the output. It can be a simple generator with one transistor, the same as for radio tapping, but it needs to be tuned to the frequency of the received station. Interference may be difficult if the station being received is very strong or if the receiver has an external (roof) antenna.
    But it should be added that such actions are illegal.

    The construction and use of transmitters up to 20mW is reportedly legal and does not require any permits.

    Hi!!! 30 springs will probably be when I made my first tests with generators. Then I made a generator using a Soviet G 807 tube and imagine that the Jubilat radio receiver did not receive stations on all bands when the generator was operating - it was probably simply clogged.

    The issue of radio interference is almost as old as radio itself! Generally speaking, it can be done selectively (disturbing only one frequency) or broadband. In both cases, you can jam or dampen. Jamming involves strong modulation with a signal that is heard on the radio much stronger than the signal of a radio station. Attenuation involves the creation of an unmodulated frequency with a very high intensity, which mutes the useful signal. This usually happens because ARW reduces the gain and the broadcast is muted. Detailed descriptions cannot be included because it would be complicity in a crime. Jamming and disturbing radio reception is PROHIBITED.

    Or maybe build a low-power transmitter with an operating frequency of 10.7 MHz? Taking into account that most receivers are made "economically" (no IF trap at the input), it would be possible to disturb the reception of FM radio without having to constantly tune in to the program currently being received by the neighbor.

    Only then you and He won`t listen to anything!!!
    And what`s done? Did Father Director get under your skin that much?

    Turn on the computer close to the wall
    it interferes so much that you can`t hear anything on long and medium-length

    I don`t have a computer in my room. I find it hard to believe what you wrote ;)

    Apparently a CB or other radio with a poorly tuned antenna is good... :D

    I have a radio on my computer and it doesn`t matter to me
    strong interference
    only strong stations on FM

    Hello. The only question is whether when you manage to mute your neighbor`s radio, he won`t play the music from the CD?

    NO. The problem is that a person does not have a "sleep" timer on the radio, he sleeps and the radio plays all night long.

    For a mohair radio listener, all you need is a mini-bug-eavesdropper tuned to the red-tailed radio frequency. You can buy a kit for self-assembly for the equivalent of several Keleris and, if properly assembled and tuned, you will have a lot of fun. This is theoretically because: Of course, it is immoral, reprehensible and you are also committing a mortal sin, so think about it 666 times.

    :] I recently saw a cool thing at the mp3 transmitter market. such a tiny device powered by a AAA battery with one cable that you connect to your disk drive or mp3 player. You set the frequency in the radio, the frequency in this device and you can hear it in the radio speakers.
    Range approx. 30m Intended for a car ;)

    In such a case, only a transmitter with frequency adjustment is available, and this costs over PLN 50 :(

    I am thinking about building such a transmitter https://www.elektroda.pl/rtvforum/topic197583.html but I am afraid that it will not be possible to tune it to a specific frequency. Please correct me if I`m wrong ;)

    I don`t want to start a new topic because it is a similar problem. Can you disturb a neighbor who plays a CD player or tape recorder at full volume at night? Some sound crackling from the speakers might discourage him. I don`t know if it`s possible, because there is no radio reception here. But, for example, a cell phone is sometimes audible in amplifiers. Maybe something along those lines?

    Regards

    If he has decent equipment, nothing can disturb the amplifier. Well, unless it`s a 1 kW transmitter with an antenna as close as possible to the wires to the speakers, and even then that`s not very certain, and besides, it`s absolutely illegal and reprehensible. Not to mention the costs of building the power supply for such a transmitter. A much more effective solution is to turn off the electricity.

    Thanks for the answer. I thought it wouldn`t be easy. But, by the way, it is also illegal and reprehensible to play at full volume at night (especially during high school leaving exams or university entrance exams).

    Of course, disturbing the peace at night is reprehensible. And that`s what the police are for.

    make yourself a simple transmitter with frequency control and connect a simple generator to the MCZ input, e.g. 1khz, and you need to know what radio your neighbor is receiving and all you need to do is tune in and that`s it

    Or maybe you can annoy him with a cell phone, put him in the GPS with the GG switched on and place him against the wall, close to the amp.
    Probably once a minute the cell phone in GG has gone through data packets - it depends on the phone, but if someone listens to it very loudly, it may irritate them.

    The Tesla coil also interferes... When I connected mine, the TV was going crazy in the other room, I didn`t check it on the radio, but I think it should work...

Topic summary

The discussion revolves around methods to intentionally disturb radio receiver operation, particularly in the FM frequency range (88-108 MHz). Users suggest various techniques, including using RF generators or low-power transmitters to create interference. It is noted that interference can be achieved through strong modulation or unmodulated signals, but such actions are illegal. Some users mention practical experiences with devices like Tesla coils and mini transmitters, while others discuss the legality and morality of creating disturbances. The conversation highlights the challenges of jamming strong signals and the potential for unintended consequences, such as affecting other devices.
