When you define a frequency, are you defining only that particular frequency (433) or a band that is centered on that frequency (say 400-460ish)? If it does define a band, how do you tune within the band? If it does not define a band, is there a module that you would recommend with that kind of tuning capability?
The CC1101 is a low-cost sub- 1 GHz transceiver designed for very low-power wireless applications. The circuit is mainly intended for the ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency bands at 315, 433, 868, and 915 MHz, but can easily be programmed for operation at otherfrequencies in the 300-348 MHz, 387-464 MHz and 779-928 MHz bands. Features input voltage :3.3V maximum operating speed: 500kbps, support 2-FSK, GFSK and MSK modulation can be modify the baud rate, power, frequency and other related parameters by software high sensitivity (
How is this a jammer? All you're doing is transmitting hello world. There is 1000s of devices running on 433MHz all in vicinity of one another. This will not "jam" your car fob and prevent it from working. What you've built here is not illegal to build at all. There's kids electronics projects that build these.
What do you think a jammer does? I have a few other videos showing them working and explaining the concepts, as far as 1000s of devices transmitting on 443MHz in the same area and not interfering with each other I would ask you this. Why can we not see them on the spectrum analyser?
Are you using a 3v Arduino ? Everything I’m reading about the cc1101 says it won’t take 5v from input/output pins. Also what sort of range have you tested this to ?
Great video! I have been wondering how someone could make an LRAD (Long Range Accoustic Device). Could creating "sound lazers" be easily done? It would be neat to be able to transmit a lightly spoken word or even a whisper to an individual across a large field; no one else would be able to hear it.
Can you make RF SA using magical module Si4463 or 32 With wide band sweeping capability and Also a rf signal source using arduino, esp, pi?and gui tft display?
I wonder if an Arduino program that scan's then jams signals it receives.. or 2 Arduinos.. one scanning and the other jamming... Oh that wouldn't work will it.. No.. But could something like that be used to jam frequency hoping signal's.. Military technology is dodgy to discuss. 😅
Hi i need your help to build laser jammer high distance for p0l1cE radar. I need to dedect the signal send to my car pamper from p0l1ce laser radar. Need to dedect the signal from 750nm-1000nm ligth but with mhz signal from 10mhz- 3000mhz. The minimum distance must to be 1000km. Am wondering if this what am asking can be real. I don't care if is legal or not. I am from Cyprus everything is legal and everything is not😂
Hi! It's a nice idea, just I'm looking for bluetooth jammer, as I see this device is not in range bluetooth, or I'm wrong? Probaply you coud advice some solution - my neighbor use bluetooth loudspecker at night..
Vitalii M bluetooth is wifi so you can find the frequency and set it in the program. Set an interval so it jams on and off so they think thier shit broken 😂
Why do you need a jammer device, for what? Why to support making illegal electronics to make people life miserable? Use your time to do something good.
Hi there. Re drones and security. Boundary security is important at my farm .Can you kindly help with a raspberry pi or similar land F band radar unit please? Diy boundary radar theses days is important . Adding a 360 degree rotating co linear panel antenna with a linear 10w Rf output including code for size of object differential algorithm (bird, drone,man or car ) at 700m would be awesome. Im happy to buy a radar kit on your web site ( F band ) pre programed would be fantastic. I can also be keen buy the Gerber file for printing the 18 inch x 18 inch co linear array PCB and have your filter plus a tuned circuit design fitted to pcb aerial. Have potchers on farm problems. Thanks mate for your videos From Andrew
Does it jam the Downlike for GSM Which is the 960 Mhz ? Cuz i saw the data sheet for cc1101 it says the max frequency is 915Mhz which is the uplink for GSM Please I Need help as soon as possible for graduation project
It could. Although if you are just wanting to interrupt 2G GSM phones and have access to good SDRs you can set up a fake base station and DOS the phones that way
Hi. I’m a newbie and would like a ready made drone jammer to stop it prying in the house and garden . Is there any pre programmed modules to buy and or build. Thanks for any help.
You have to see how the drone communicates with the pilot. If its wifi, which is common, you can try using a esp wifi deauther (lots of tutorials on youtube, cost 2-5€).
Someone has an asshole neighbor. The best legal solution is an 8 AM retaliation after their late night with something obnoxious. Anything on the Gitmo playlist at 11 equally loud.
Greetings from Florida! I wanted to ask, so I have everything set up correctly and working (as well as an SDR to monitor transmissions) how exactly do you change the frequency? I've been searching for hours on how to and it only seems like I can do it off of some TI software through the registry. I've tried just simply changing the code radio.setCarrierFreq(CFREQ_868) to whatever I want but it doesn't seem to verify correctly because it doesn't recognize the new frequency, any ideas on what I'm doing wrong?
I dont have the code in front of me but I would double check the documentation to make sure you are using the correct commands. I will have a look when I get a chance :)
@@Brains933 So I actually just figured it out, the way I managed to do it was by first downloading the SmartRF software by TI, finding the CC1101 on the screen, clicking it and choosing "open RF device in offline mode" and then from there it should show you a screen and to the right (you'll need to enable RF Parameters and Register View in the View setting at the top) you'll be able to choose FREQ0, FREQ1, and FREQ2. You'll need the value hex code later. You then simply change the base frequency on the screen to whatever you want, go into the CC1101.h file in the library and then choose one of the frequencies you don't mind getting rid of and simply changing their values in the file. (Just leave it the same name or you may have problems whenever you choose it using the CFREQ_ command). After that simply edit it in the main arduino coding to the frequency in which you edited. Now I may have done this entirely wrong since I'm not the best at understanding script but I did manage to get it done if anyone else has this issue. It would be great if someone could make a library with a bunch of channels together for easy changing. Anyways, cheers!
Hi grant just doing this on my laptop now is there a way to send the (hello word) faster ? I set the send delay to 0 but that’s not affected the send speed ? Any ideas pal
Hello mate! Another great video! (hats off) Thank you so much! My supervisor gave me this project but I couldn't find any useful tuitorials on the web! But can you please make another video and elaborate this one? I really hoped you would be doing this project on a bread board, because that would have been really helpful for students like me. If you have the time to spare please make another video.( I would be really greatful! As my final year project depends on it!) And if not can you atleast tell the connections between the pins? Thanks for your support and help!

Wi-Fi and Bluetooth both operate on the 2.54ghz spectrum, although some Wi-Fi also works on the 5ghz spectrum. So if you jam the 2.4ghz Wi-Fi you'll also jam Bluetooth.
Yeah I am going to do a Breadboard video soon but if you look at the code from Github it has the wiring and pin numbers at the top. I have also put them in the description
Correct. I believe I mentioned that in the video. I also have a video talking about why they are illegal and as you pointed out that they are easy to find.
You never get jail time for this in the US... I'm very familiar with us laws/justice system. At most, you'll recieve a fine. That is unless it's used in the commission of another crime.... You guys kill me- constantly crying "THATS ILLEGAL!" I live my life and base my actions on what I feel is right or wrong! Its pathetic how the sheep do as they're told... No chains needed... They know you won't dare escape or even think about breaking masters rules.

That's usually what people use to steal cars. The program he was running showed what frequency his key fob was. This is strictly a 433mhz chip so you'd need a chip that can change frequencies if you want to clone.
