- [ENABLE CAPTIONS!] I am giving you the universal RF jammer that operates within sub 1GHz RF range. It is constructed of Arduino Pro Micro ( 3.3V , 8MHz ) and CC1101 board. Total cost is below 10 USD, the output power is 10mW.
All of the project details are available here : github.com/mcore1976/cc1101-j...
The jammer can succesfully jam car keys, wireless doorbells, drones and other devices that operate within 300-348 MHz, 387-464 MHz and 779-928 MHz. The output radio power is 10mW but it can be easily extende by adding cheap RF output amplifiers. This device can also protect your car from being stolen by jamming hackers RF device that are sending keycodes on particular car's freqency... In the video I am using great SDR++ tool for graphical RF output.
Remember that RF jamming may be illegal in your country !
This video is only for educational purposes showing how to integrate CC1101 board with Arduino boards.

Damn Buddy, Bustin out the AVR Assembly on us!!! Sweet!!!!
u answer every question, i like it
Me too!
Great work 👍👍
Thanks its working great for me
Hey ill pay u too show how to do it
great job!!
big like and subscribed as well ! great coding , very nice video
look for V2 version of this jammer on my github page, it is even simpler and more configurable
Thank you so much nice tuto
Все получилось, скачал последнюю версию IDE 1.8.19. -Помоему. Спосибо вам огромное за проект!!!!!. Надо делать усилок
you are welcome !
Nice bro
mając arduino 16mhz i 5v można zastować modulik zmiany zasilania z 5 na 3,3V (jak widzę na stronie sklepów są dostepne takie rozwiązania jak ktoś już posiada wersję 5v i nie chce zmieniać płytki arduino)
Great and very detailed explanation, thank you for this.
I really dont know nothing about the frequencys but i would like to jamm one particular thing that operates on 433.92mhz... what frequency do i need to write in the code?
This frequency is used by my neighbors for some kind of motor, the problem is that this motor is really loud and i would like to jamm this thing so hopefully thei change it soon 🤣.
Please help me 😁
there is already such line in the code with the value 432900000 you just need to uncomment it
Hi many thanks for your video ! what are you suggesting to use as component to amplify the power of cc1101 ? maybe around 3 Watts
there is a lot of RF power amplifiers on Aliexpress. I did not test them but if I would like to buy I one would be searching for something tuned to single frequency like 315MHz or 433MHz
Thank you for the video and the prompt content. Have you ever tested Samy Kamkar's Rolljam device?
not yet but I am planning to make my own.
It would be very interesting to share this project with us.
Hello.Interested in the question.The entire compilation takes place.But in the middle there is a red-WARNING-"F_CPU" redefined and in this spirit 16 lines.something is missing. How are you?
which source file have you used ?
Сделал усилок, но женить его с CC1101 плохо получается. Поэтому решил с si4432 он вроде по мощней. Или дайте совет, какой усь ставить
I have Arduino Pro Micro but unfortunately 5V / 16MHz version. To connect it to C1101 I use bi-directional logic level converters for all signals. Additionally I use step down converter to get 3,3V for power supply. For rev.1 of your code - I changed FCPU value from 8 to 16Mhz. Do I need modify something more to get it work?
I think you should also check delay functions because they may be tuned to 8MHz clock
First of all great job sir
Sir I am a student of
Electronics 2nd year I am working on a similar project to jam radio transmitter named fsi6 used for drone controlling, but it work on Frequency ranges between 2 GHz to 2.7 GHz
So please tell me what necessary changes I can do to jam in between this frequency
Warm regards
(Note , I am aware of the fact that CC 1101 module deal with maximum frequency of 982 mhz)
use board module with CC2500 chip. According to this description it may work with my code for cc1101-tool

Nice video dude, like always. I sent an email with a question related to a rf module with potential to be used as a jammer, but I cant make it work. Hope you find time to give it a read. Thanks.
yes I have seen this mail. I have 2 of these modules but the are using FSK modulation and are not suitable even though they have bigger RF power. For best jamming we need something that supports OOK on off keying techniques
But cc1101 isn't that versetile for continuing frequency sweeping so how any frequency instead of decreat??
As mentioned in data sheet
".. frequency bands at 315, 433, 868, and 915 MHz, but can easily be programmed for operation at other frequencies in the 300-348 MHz, 387-464 MHz and 779-928 MHz bands."
There is some gap in frequency like between 348-387 and 464-779 Mhz?
yes there is a gap in frequencies
Hello and thank you for the video, will it jam a stereo integrated amplifier/mixer/microphone/speakers/hifi and stuff like that?
Hi, this is for radio frequency jamming like wireless keys or remote controls. If you want to jam microphones there is separated video here th-cam.com/video/8RgoYlrgW4s/w-d-xo.html For speakers and audio amplifiers I do not have solution.. yet
Hi, thank you for your tutorial. How many meters can it disrupt radio waves?
normally 50-100m but you may always attach some RF amplifier. There is a lot of them in chineese shops
I would like to thank you for your great posts in you tube and ask a small question ,hope you consider .
I just made the rf jammer with cc1101 and pro mini and every thing is perfect but the noise signals stop after a while about 30 minuites for axample , and i have to reset the circuit . do you have any idea why is it so !??
Hi, I think it may be somehow related to the battery power. Maybe it disconnects after sometime (some powerbanks like to do it).
@@justanengineer5599but i use dc adaptor ….
Hi. This was very informative video, thanks for sharing. Is there any areangement where we can use 315 and 433 mhz simultaneously without changing frequencies through software.
As far as I know NO. You would have to build 2 of such units to achieve this effect or relay on fast frequency hoppng of CC1101 chip. But hopping means less effectiveness of jamming
You could use an ESP8266 or ESP32, both programmable using Arduino, and 2 RF boards.
The ESPs are much faster than a mini or micro Arduino
Hi do you know a way to filter the Nosie the jammer is making in order to capture a clean signal from a car key.
you need to shift a bit the frequency of the jammer in comparision to the original signal of the key (100-300 khz). Then you will be able to record original signal with rtlsdr device
I really like it I would like to know how far you can jam with this device what is the radius please if you can give me some info
50-100m depending on what you are trying to jam

even with this board you can use oled screen and buttons. Unfortunatelly I do not have free time to extend the source code for this features
Well done bro . need 500khz/2mhz jammer, this circuit work?
According to CC1101 specification it will work only between 300MHz - 928 MHz. So the answer is no, it should not. I admit I havent tried configure it to work on such low frequencies. However
You may try to put 2MHz value to the code to see if it can work... Please use revision v2 of the code : raw.githubusercontent.com/mcore1976/cc1101-jammer/main/arduino-pro-MINI-cc1101-jammer-v2.ino.

hello Im new to electronics but once its all put together and wired up and has the right modules when you plug it in to a Mac should the windows the control the modules pop up and what frequency do you use to black a radio signal the same as the brain thnx!.
the brain can only be controlled by social media as tiktok, facebook, twitter, instagram. Thats the only way and moreover the most effective!
hey mate. lov all you vidoes.. and I want to build this.. but is there a way I can use only 1 pro micro. and then connect to 3 or 4 pcs of cc1101. so I have one for 315. one for 433/434 and one for 868 or maybe 4 with the last for 915 . and can you make a code for that. I will pay you for your service if you can.. and by the way, keep op the good work. this is so nice to watch and lean form you. thanks from Denmark,
as far as I know you can connect multiple CC1101 to the same SPI lines (MOSI, MISO,SCLK) but different CS/SS pins. Normally even SmartRC library supports I think 2 CC1101 boards at a time. The only problem is that you need to keep some settings of each CC1101 board in the microcontroller memory which may pose some problems
What source would you use to power this up on the go? Would a powerbank with 5.1V output be the right choice ? Does the unit have a transformer? (Newbie to electronics)
regular usb 5V powerbank would be just fine. It draws less than 50mA

Świetny film ! to jest dopiero powód do dumy z bycia Polakiem haha. Mam pytanie bo podczas kompilacji kodu Arduino IDE nie rozpoznaje "#include " i wyskakuje błąd : avr/boot.h: No such file or directory a doczytałem się, że kod autora "Panagiotis Karagiannis", na którym bazowany był twój kod działał jedynie na urzadzeniach z linuxem - czy dlatego to nie dziala u mnie? Jeśli nie to może wiesz jaki może być inny powód? Też warto chyba dodać, że używam ESP8266-12E. Ta płytka też działa na 3.3V i z resztą widziałem filmik, na którym ktoś używał tego konkretnego modułu z nią, więc jestem pewny że są kompatybilne. Może w kodzie to coś zmienia i to robi jakiś problem (?) Próbowałem także zainstalować tą biblioteke PANSTAMP o której mowa w komentarzach na początku skryptu ale znalazłem tylko jakieś archiwalne strony na których albo linki wygasły albo prowadziły do bibliotek arduino które nie działały. napewno jest jakiś prostszy sposób żeby uporać się z tym problemem ale nie wiem jak...

Hi. I repeated your example. I used only an arduino nano (5V / 16MHZ + level shifter) - the result is the same as in the video (I also used an RTL SDR receiver). The result is good only if we do not jump through the channels, but at the same time the frequency of the alarm keychain may stand aside from the configured frequency. And if you start jumping through channels, then the signal level is naturally less - this is logical, but at the same time there is a big chance to miss the moment when the victim uses the signal source. what makes jummer not effective! If you are the author of the code, then how can I correct the code so that the program routinely iterates through channels, say, starting with frequency 433 and ending with frequency 435 and at the same time get a solid spectrum of noise?
Hi. The CC1101 can only send data at one channel at a time. It can do fast hopping between channels, but it is still limited. You can play with such settings like : modulation (ELECHOUSE_cc1101.setModulation) , channel spacing ( ELECHOUSE_cc1101.setChsp) in a file : "arduino-pro-micro-cc1101-jammer-v2.ino" that uses SmartRC library. However the best would be to build several jammers each tuned to different baseband and switch them on simultaneously.
See my latest video that will be published today, that may help you a bit with jamming stuff, I am also showing this function there.
@@justanengineer5599 Cool😁. I did some experiments, a results you cane find on my channel 👍🤝
Hello sir, can I use nrf24 instead of cc1101? Thank you for this nice explanation. I wish you success.
no, this source code is compatible only with cc1101. I am currently working on NRF24L01 version
@@justanengineer5599 Thank you sir for the reply cc1101 is not available in my city only rnf24 is available so I asked you if I could replace this part
you can buy everything directly from china. Try on www.aliexpress.com
I have a m1101d here and it’s connected to my arduino nano. I am trying to program it to where it can be 315 MHz as it has a cc1101 chip and is able to do this according to seller. How would I do this?
there is a field in the code that selects the base frequency. Watch the video carefully
Does those kind of frequencies jam the cell phone 4G as well? By the way it is very great video and concept. I hope next video will be about small base Telecommunication stations instead of those huge ones that we see in the ground since you could make everything simple and much way smaller in size 💯💯💯
the CC1101 board can use frequency within 300-348 MHz, 387-464 MHz and 779-928 MHz ranges. If your cellular network uses some of them then yes, it can jamm cell phone when nearby.
Will RF Jammers like this one jam both FM and AM radios 📻 ?
yes.
You can change the code with potentiometer to choice the 433 or 980 ...
good idea but you would need some display as well to indicate what is set
hi sir . ı want to ask can we use to jam with same code with CC2500 2.4ghz if we add library ?
no, this is completely different chip.You would have to use different library like this one here github.com/yasiralijaved/Arduino-CC2500-Library I will probably prepare the 2.4GHz jammer for this board in the future
can it be connected directly to a usb of the 5v power bank?
yes of course. The Arduino pro micro converts 5V to 3.3V to power CC1101 board
Скажите на si4432 возможно сделать? Если возможно, то дайте дельный совет.
I want to use Ebyte E07-433M20S (20 dBm) instead of C1101 (10dBm). How can I use the same code to get 20dBm output?
if you meant this module www.ebyte.com/en/downpdf.aspx?id=457
then no changes are needed in the code
can i use a 5v to 3.3v voltage divider circuit with resistors to make the cc1101 run from a 5v pro micro. It technically should work right? Also can I make it work with 16mhz?
Yes, resistor divider would work but you have to ensure enough current like up to 50mA. If you want to use 16MHz based Arduino please upload V2 version of the source code : raw.githubusercontent.com/mcore1976/cc1101-jammer/main/arduino-pro-micro-cc1101-jammer-v2.ino but you need to upload also CC1101 library

Someone asked (about the Same question ) --- However, I'm interested in jamming a band (range) of frequencies. ( ie, 600-650 mhz ) how can I do that?
The source code allows to use this frequency but I do not think the chip can handle this. You would have to build an ordinary old LC based generator for this
👍
does this only work with arduino pro micro? I wanna try it with Esp32 or maybe wemos d1 mini
no this one not, but try my cc1101-tool which supports Wemos D1 mini and has built in jamming capability. I am showing it in my newer videos
Can you explain how to jam low frequency (0.5Mhz - 100Mhz) signal within 10meters range?
for this you need to build analog LC generator with MOSFET transistor like this en.m.wikipedia.org/wiki/Armstrong_oscillator

100m
can it be use to jam bluetooth device?
no. bluetooth operates on 2.4GHz while this device jams
can i use Attiny85 Digispark ?
unfortunately not. ATTINY 85 does not have full SPI bus. I have tried to make Digispark work with CC1101 module but I failed
HOW CAN I CONTACT YOU I HAVE A QUESTION I WOULD LIKE TO ASK YOU...
THANKS
GEORGE
my email address is in the channel description
can i replace arduino micro pro with nodemcu esp8266 or digispark ? without change code
if you use version 2 of my code here : raw.githubusercontent.com/mcore1976/cc1101-jammer/main/arduino-pro-MINI-cc1101-jammer-v2.ino and following library from Little S@tan then it may work github.com/LSatan/SmartRC-CC1101-Driver-Lib
@@justanengineer5599 thank you . i will try and share result here .
I was gonna ask the same , I have a esp8266 , but would it work without the rf module ? I mean esp8266 is already emitting some kind of signal
yes it should work. CC1101 operates on differeny
t radio band than ESP.
how would i make a device using the cc1101 to clone car keys and garage doors?
it would be a variation of my project for CC1101 based radio communicator. You would need Arduino Pro Micro 3.3V/8MHz and CC1101 board. The code would have to be modified to listen radio sequence and then replaying it (th-cam.com/video/aRe3WXXtzLU/w-d-xo.html ). However first you need Universal Radio Hacker software and RTLSDR dongle to find out information about the keys you want to clone - modulation type, frequency, what preamble is used and so on ( th-cam.com/video/jziWQA8Wvp4/w-d-xo.html )
To conclude - in general it is not easy for novice
check my latest project on github : github.com/mcore1976/cc1101-tool
This is the tool you asked for. It is easy to do ultra cheap Yardstick One equivalent
with this Is it possible to generate 1800-2300 MHz ?? Or how to achieve that ?
different chip from CC series is needed
Go ahead and start asking questions on how to turn an "ANTI DIRECTED ENERGY WEAPON" into the exact same we/you/us/US/U.S./U.S.A. users use as an attack signal.. I was *PERSONALLY taught by the f.c.c. and e.p.a. themselves that 1 gigahetz(1,000 000,000Htz) is the beginning of the end 2 g was a punch in the face 3g was *JUST ENOUGH" 4G was sharpening the *SPEAR.. and 5g was a kill shot.. and 10g means their coming back for more.. T.D.m.atch a.k.a. Anti DIRECTED ENERGY WEAPON AGENCY
have you found the solution for 1800-2300 mhz if yes please can you share
Can we use this for lora frequency?
yes
Do u know of a device that is not diy and plugin or battery operated that i can buy for microphone jammer?
there are some devices called microphone jammer for usd 500+ you can find them on www.aliexpress.com
@@justanengineer5599 expensive!
How to increase the power and then distance ?
use CC1101 module with built in LNB
Can be worked in vhf frequency?
uhf only
What if you tune this to the cellular frequency like 3G and 4G would it jam it??
yes but short range
@@justanengineer5599 Can it be under 50 meters or if there's a way to lower the range to about 20 meters?
up to 1m I guess
@@justanengineer5599 that's better
It's possible to increase the 10mw power tx?
yes you need to attach RF amplifier board from chineese shops
@@justanengineer5599 Thanks 👍
Will this work between 500mhz to 700mhz? And will this work for tv channels too?
the working range is 300-348 MHz, 387-464 MHz and 779-928 MHz
@@justanengineer5599 any way for the above frequency? Thanks for the reply
No. It has this limitation built in.
@@justanengineer5599 maybe harmonics in the 600-700 MHz range. But you‘d probably need a amplifier.
@ can you please explain this a more how to do it. because i am newbie with these things

w opisie kanału masz mojego maila
Szukalem patrzylem i nie znalazlem…
Jak chcesz zrobić taki projekt jak głupiego emaila nie potrafisz odnaleźć? Nawet w tym filmie jest on widoczny jak przeglądam kod programu.. Muszę wiedzieć czy rozmawiam z człowiekiem czy z jakimś chatGPT :-) Ale masz jeszcze jedną szansę - zajrzyj na mój github (masz link w opisie filmu) i przejrzyj choć trochę mojego source code w języku C z dowolnego projektu. W kilku pierwszych linijkach kodu zrodlowego jest mój email. Jak przejdziesz tą próbę to może będziesz w stanie się odpytać o więcej

Work for Bluetooth?
works below 1GHz and Bluetooth is 2.4GHz. So it does not work for Bluetooth
Hi is there anything to jam the stupid wireless speaker ?
it is not easy because bluetooth technology is using frequency hopping thus it is less susceptible for jamming. I am working on NRF24L01 based wifi jammer now
This may helps th-cam.com/video/N8jsyNExt9E/w-d-xo.html
Can it run at 2000MHz even with an LNA 5M-6000MHz subwoofer or not ???
this one works up to 1GHz = 1000MHz
@@justanengineer5599 And if you add a 5 mhz-6 ghz subwoofer to it, it will stop at 1 ghz and will not exceed it???
yes
Does nrf24 work instead of cc1101 please reply
no. there has to be different source code. I am working on it
@@justanengineer5599 Please help me I want to run nrf24 like cc1101 can you help me 😢
nrf24l01 is completely different chip than cc101 and works only on one frequency 2400 Mhz
Can I use Arduino Nano or Arduino Uno?
Arduino Nano or any different if provides 3.3V output and 8MHz clock. Look for v2 version of my code : raw.githubusercontent.com/mcore1976/cc1101-jammer/main/arduino-pro-micro-cc1101-jammer-v2.ino
@@justanengineer5599 i ordered a pro micro with 16mhz clock will it work ?
it will not work unless you provide 3.3v vcc to CC1101 board. Also you have to use this file for upload : raw.githubusercontent.com/mcore1976/cc1101-jammer/main/arduino-pro-micro-cc1101-jammer-v2.ino and attach SmartRC zip library to your sketch
can this setup be used for a replay attack?
yes of course. But you need to know the sequence to send. It can be recorded by Universal Radio Hacker first
@@justanengineer5599 I have the sequence, what else do I need to do?
Hello sir, I want to make a jammer with frequency 800MHz to 3000MHz which will jam cell phone communications within 10 meters. Can you help me... Please reply
It is not possible with CC1101 module. Jamming cell towers requires huge power
@@justanengineer5599 can you help me with my university project
my project is jamming 4g cellular signal with in 2 meter range
i want to jam one just phone
thank you for your answer.
jamming cell phones is illegal do not tell me that it is university project. what if you jamm someones phone who is doing an emergency call? you may go to jail for such activities
Also jamming gsm locators of stolen cars is probably also aplication of such jammers...
@@justanengineer5599 any clue where to find sources for 5ghz jammers? I mean they're being produced but I can't find anything even if I seach for teardowns. Really strange tbh

really? PD (port D) are pins 0-7. PB (port B) are pins 8-13 :-) look here : www.circuito.io/blog/arduino-uno-pinout/
@@justanengineer5599 Thank you. I didn't know Arduino well, so I thought Arduino Uno didn't have pins I'll make it after watching the video😁
I want to use this circuit to disrupt the TV signal passing through the coaxial cable. Will this circuit work for me? or how can I update it?
coaxial cable is shielded and that prevents from such kind of signal disruption
