[@Xavier_Everwhere]

Great Scott Sir, there is a another channel name ET DISCOVER has made a signal jammer and signal booster, so sir i kindly request🙏🏻🙏🏻 you to investigate on his video also sir.

[@edwardfletcher7790]

Thank you for exposing this idiocy !! Dave from EEVBlog exposes them too, so you're in good company 👍

[@IshaqIbrahim3]

If there is an electronic component that is common across the videos, then they might be scamming people to empty out excess of junk they have in their stores by making the videos.

[@infra-blue]

expose more of these channels that show fake and misinformative content. Thanks a lot for your work

[@greatscottlab]

Will do :-) Thanks

[@Speeder84XL]

Yes, that's great - expose them as much as you can. I acutally don't really care, if some people "steal money" from a greedy company like google (who has ruined KZbin, compared to what it once was, anyway), by getting payed for views, that would otherwise not be there (because that's what all is about. There are probably very few people who put up fake content, just for fun. At least not electronics - political content could be a different story though. It's pretty much all about geting an easy way to make money). But, it has gotten to a level where it indirectly becomes a problem foreveryone - especially beginers (who try to build shit that doesn't work and often think they do something wrong them self and because of that wastes a lot of time). Like 50% of KZbin content is fake nowadays.

Yeah, just like ElectoBoom with the so called "free energy" videos

[@adilsongoliveira]

You are doing a great service by debunking their disservice. I started with electronics when I was 14 (over 40 years ago) and though it is not my occupation I still play around with it as a hobby. What those channels are doing is beyond dishonest because they not only present BS as facts but also discourage people who want to learn. They will try and make one of those circuits work when it doesn't they won't be able to understand why which may frustrate them to the point of giving up. So, yes, keep fighting the good fight :)

[@lunalangton5776]

If people who build jammers get frustrated and give up, good. But they're welcome to learn how to build non-interfering transmitters that should be well documented.

Even the design of an antenna for this purpose is a science for its own.

[@greatscottlab]

True

[@ДимитърАндонов-ъ7е]

Some people make thesis about antenna design for these frequencies 😀 and in these videos the dude just coils wire...

[@irreverend_]

​​@@ДимитърАндонов-ъ7еI mean to be fair at those frequencies a little bit of coiled wire (of the correct length of course) would generally suffice. Receiving 1090mhz ADS-B from aeroplanes only needs about a 6.5cm dipole antenna (so about 13cm total). EDIT Which is exactly what I have attached to my window, furthest plane I've picked up so far with full location data being 381km away

[@mattsadventureswithart5764]

​@@irreverend_ That is a genuinely intriguing idea... I don't need another hobby. I don't need another hobby. I don't need another hobby... Oh, dear :(

[@BalticLab]

@@ДимитърАндонов-ъ7е That "just coils wire" is called a helical antenna and perfectly legit for GSM applications. There are dual band and even quad band designs out there. People might write a thesis about novel antenna designs, but this isn't novel. People also cover pain management in their thesis, yet you're able to simply take an Ibruprofen against headache despite lacking a medical degree. It's really not that deep 🙂

[@ANANTHASANKAR_UA]

Absolutely right!! We can’t block or boost mobile RF signal by simply these things. The mobile RF system use complex modulation technique such as OFDMA and transmission technique such as MIMO will make them more immune to external interferences. The frequency hopping spread spectrum technique will spread the signal over a wide frequency range, making it more resistant to interference and noise. Modern mobile communication systems employ sophisticated error detection and correction algorithms, such as Forward Error Correction (FEC) and Automatic Repeat request (ARQ). These techniques detect errors in the received data and correct them automatically. It also adapt to changing conditions by adjusting parameters like transmission power, modulation schemes, frequency band and data rates based on environmental conditions. From these observations it is very clear that mobile jamming / boosting is not a simple task. It requires more specialized RF IC and well-designed antenna systems along with complex signal processing algorithms.

FHSS isn't used on LTE/5G and if there only is 900 MHz GSM/LTE available, a simple single band jammer would technically be enough. However, often times you have all sorts of bands available.

[@wireless80211x]

Industry standard for boosting are Cel-Fi GO units.

[@npiper]

RF jamming is EXTREMELY simple, so simple in fact it is possible to do it accidentally, all you have to do is (metaphorically) scream louder than the nearest tower on all the frequencies you want to block. What isn't simple is SELECTIVELY jamming ONLY mobile phone signals and doing it in a way that doesn't end up with you destroying your device while a representative of the FCC (or your local equivalent) observes you.

[@DreamsOfTheMind-video]

Expose more of this crap. Some people think they can tell you anything, so it is good to expose them. And on the other side, its also educative... We all learn from those "mistakes". Thank you Scott!

[@SuperFredAZ]

I designed television front end for several TV manufaturers years ago. You are 100% correct, keep exposing the frauds.

[@AG3n3ricHuman]

While it's obvious that circuits like these can't work at radio frequencies, it should be noted that the capacitive load of a passive scope probe will affect the circuit and most common oscilloscopes can't measure such high frequencies anyway.

[@ziggfreud9820]

They in fact can with the right set up.

[@JaenEngineering]

I'm down with debunking some more of these circuits, or even the opposite, proving some of them useful. A regular series of "Two of these designs are junk, but the third actually works. Can you guess which one" could actually be a good deal of fun.

[@greatscottlab]

Lovely idea. Not sure how easy it will be to actually do. But I put it on my to do list.

[@josbouten]

It is almost impossible to prevent people from finding schematics of non working electronic devices. But what one can do is not spread schematics or link to them if one has not tested them or does not know whether it is a working design or not. In a forum about electronics I visit on a regular basis we started including comments IN the image of a schematic stating whether a design is TESTED/WORKING or UNTESTED, so that if the schematic is picked up by some search engine (typically the text normally accompanying the schematic is lost), the status of the schematic is clear to the person finding it. This will hopefully help a beginner who can not see for himself whether a circuit makes sense or not to decide whether he wants to spend time and money on it or not.

[@simontillson482]

I applaud this schematic labelling idea. Other sites should do this too.

[@StrsAmbrg]

How could KZbin missed that channel? I have seen many channels, especially related to health, were banned or at least were suspended temporary, due to KZbin accused them spread fake information.

[@simontillson482]

I guess in the case of fake circuits, the damage is limited to release of magic smoke, general annoyance, sadness and a potential to drop electronics as a hobby. Unfortunately, this doesn’t count as serious enough as far as YT is concerned. Shame.

@@StrsAmbrg My point was that while it may be fake information, an electronics video doesn’t usually present any danger to the public (unless they’re giving instructions on how to build dangerous devices, but even then I think we can mostly agree that huge lasers and kilovolt power supplies are obviously dangerous and they mostly get away with that anyway, by including suitable warnings - StyroPyro and many others wouldn’t have a channel otherwise!). The situation with fake information in health videos is way more serious and dangerous, which is why they get taken down a lot more often.

[@ejonesss]

and even if the jammer circuits work and you can jam the cell phones you have to be so close to the device you want to jam the fcc could not detect and get evidence (unless you are jamming the fcc agent's phone in witch case they would still get bars on their phone as there is no verification or authentication to the tower just to give you bars). all you need is a simple oscillator to generate the fequency and some antenna circuit to make the signal into rf. you can even make a transmitter out of a crystal oscillator from vintage computer hardware they are found inside of a square or rectangle metal can with 4 pins they are used to generate clock signals for logic. without a signal to modulate into the carrier you can still jam a radio. power a 1 mhz crystal oscillator pulled from 80s computer boards and bring it near an am radio tuned to 1000 khz and the station will go blank. the reason most jammers get caught is because they use lower frequencies witch require more power and jam other devices near the frequencies (like the weather forecasting community feared with 5g networking). however such jammers could in theory be used to force people to use the chip or swipe for their credit card by jamming the signal used by the contactless payment system and force the customer to pay with chip and swipe witch is easier to skim.
