I got a good laugh when he says "We don't know what's going on at 121.5 MHz" well it just so happens that 121.5 MHz is the frequency used by the ELT or Emergency Locate Transmitter that is triggered when a plane crashes. That's one frequency you really want to stay away from unless you want the feds kicking in your door.
in what country? Because a quick google search tells me that at least in the Netherlands the freq isn't being used for that anymore since 1 feb 2009.

Lol, it's like a medication warning. "Here's what this thing does! Amazing! Also, may cause severe prison time, the government destroying your life, and possible domestic terrorism charges".
I really love your videos Null Byte, maybe consider putting videos also on Bit.Tube (Blockchain / IPFS). Payouts in general are better (once bots are gone, devs working on it rn). Much better than udemy imo. You can transfer all videos from youtube to their platform in one click, would be awesome if you did it! Thanks, please keep these videos coming, i love them!
I'd definitely pay for your courses, Null Byte! I just signed up for 3 courses on Udemy: Ethical Hacking, MS Office Specialist, and Beginner C Programming. After I finish those three, I plan on taking a more in-depth white hat courses, a Linux course, and HTML/CSS. If you do decide to build a course, let us all know so we can support you!
I can see the Pi being used to transmit a signal to block a frequency but I am really surprised you can transmit considering Pi only outputs a digital signal Initially I thought you were transmitting through the SDR but only models like HackRF one can do this. I will give this a try
As an amateur radio operator and electronics technician of 30+ years I found this video pretty amusing, but also highly misleading. The amount of output power that you can generate with a Rasberry Pi is so small that "blocking" another broadcaster would be nearly impossible unless you are within perhaps 3 feet of the receiver. Under perfect conditions on an UNOCCUPIED frequency you might get a range of perhaps 100 feet, tops. You would have to have a decent sized antenna to accomplish that though. The output power that the Raspberry Pi can put out is something on the order of .005 Watts. Broadcast FM radio broadcasters typically put out 100,000+ WATTS. So, "jamming" a signal several hundred thousand times stronger is highly unlikely. In addition, the bleedover or "splatter" as hams call it, transmitting on the frequency you found is in the commercial aviation band in most of the world. So, you could be interfering with airplane communications and beacons used for airplane navigation purposes. It's not very likely with such a puny signal, but it's stupid to even attempt. If you want to transmit on the FM band it is much easier and cheaper to just get one of those $12 adapters that plays music into your car stereo from your phone or other audio device. They have more output power, a cleaner signal with less interference and greater range with a properly tuned antenna already built in. Going through all of the trouble in this video for inferior results is just a ridiculous waste of time.
If you boosted this signal to a very very very very high degree or were right next to the receiver, that might be true, but even with an optimal length cable, this has a range of about a block at maximum.
not always true. a weak signal can be radiated very well. if you take a transmitter that sends a 100mW signal into a horrible radiator and said system is at ground level it may only have a range of 100ft to 300ft maybe up to a 1/4 mile. take that same set up only have the radiator sitting up at 1,500 ft above ground level you could see a range of 15 miles or more. if you have a good radiator (1/4 wave vertical or a dipole (1/2 wave radiator)) the tiny 100mW signal will do much better in range. Several years ago I got to talk to a airline pilot on 2 meter ham band (146.52MHz actually) he was on a handheld radio with about 4 watts RF power and I was using a hand held radio as well with about 100mW of rf power (hand held radios tend to have crap antennas) he was at about 30,000 feet and about 100 miles away and had no issue talking to him for the moments he was in line of sight. So while at ground level it may not seem to have much range it could be in theory being picked up by aircraft cruising around at 30,000ft 50-150miles away
@@-thefalcon- don't matter what mode it is, if you put a signal out where it shouldn't be it is a violation. and the FAA tends to get real heavy handed with people putting signals onto the air band where they do not belong.
It's another awesome video. Can you show us please how to make Radio scanner, a police scanner or digital scanner from a Raspberry Pi. This type of scanner is expensive. Thanks again for this video.
I enjoyed the video. Thanks. How can someone add a sound coming through to your mp3 player while your song is playing? How is it that the volume is being controlled as well? Thanks for replying!!!!!!
Yeah you would want to super careful with that square wave pulse you had going there! 121MHz is in the range of frequencies used for air traffic control air/ground communications . You could endanger hundreds of lives doing that. I would definitely use a filter on this to stop spurious emission up into that band. I know this setup would be fairly short range but still could be dangerous
The raspberry PI foundation, knowing the hardware function this is based on was used for an illegal use made sure to change enough of it so that in newer chips PIFM would no longer work, to protect naive users who did not realise that emitting a FM modulated square wave would also emit on its higher harmonics frequencies in the military and avionics bands, and not only on the FM band, and thus made the user vulnerable for arrest. So no, PIFM as is, will no longer work on later models of the PI !
I am shutting down my FM station anyway and moving to HF radio. I could use my transmitter to jam pretty much anything in a 5 mile area of course i am not gona do that.
I've just spent two weeks in the cellar after my parents used this to convince me there was a zombie holocaust. They just wanted to holiday in the Maldives without me.
Hey, I'm stuck at the part where he puts the password he says its "toor", but when I put it in it doesn't work? I also tried my WiFi password if it would make a difference and it said password denied every time
Try github.com/markondej/fm_transmitter and use arecord. arecord -D hw:1,0 -c1 -d 0 -r 22050 -f S16_LE | sudo ./fm_transmitter -f 100.50 - This requires a USB Microphone, try a USB Webcam, they mostly have microphones in.
U can also attach one of those radio broadcasters u use for wireless CD player to your car. Solder on to raspi with a signal booster and that's how I messed with my neighbor which was about 40 yards away.. couldn't get any further though...
Car's FM radio started swearing after reporting a family member for committing fraud/theft using my personal information in 2018.... It's still happening almost crashed once.
We can also trap and record the radio waves emitted by a car remote when it unlocks the car and then it can me broadcasted using this tutorial ☠️☠️☠️ Awsome we will hack cars too!!
@ꀯ I install garage doors genie , Westing and liftmaster all use static codes older models have mini switches inside next to batteries like 20 tiny red switch to change your signal and you won't open your neighbor garage .yes still old tech but works . I've seen people saw into doors before they hacks
But we can also use the roll jam attack. User presses key, we capture and jam, so the car has not rolled to the next code, now we have an unspent token, user presses key again because 1st attempt did not work for them, we also capture and jam, now we have 2 unspent keys, immediately after jamming we replay the 1st key to unlock the car for the user, they are non the wiser. Now we have 1 unspent key.
Hi iam trying to do my own radio station as to play with my neighbors a little bit but I want to speak through the radio station not record and run can you help me do it on pi zero
say someone was in my backseat on their phone and this EXACT thing happened. static then familiar voices afterwards. would the person with me be the culprit?
Hey, you probs noticed it. But i love your vids. But i have a question about this one. How do i make the signal of pin 4 stronger? A long wire isn't working for me. I'm using breaboard wires.
My mother has a crazy neighbor who plays loud fm radio in his old car hours a day, on revenge on he neighbors, because someone blew the whistle on him for his ill skin-and-bone horse. It’s maybe 10-15 meters from mother’s house to said parked car. I have access to a position overlooking the car. Could I jam his car radio frequency and have it play birds chirping instead of the lousy local radio station he tunes in?
1:53 for my raspberry pi3 model b its the 3d to last pin on the right side (closest to the cpu), can anyone explain why this happens? And the first time i installed PiFmRds it failed to find the command ./pi_fm_rfs so i had to delete the entire directory ///root/PiFmRds and re clome it
i just want to put a giant damn fart like 85 taco bell meals type fart on bob fm then let the music just play again or just say “Wake Up. Wake Up. This is a Dream. Your in a Dream. Wake Up. There is something Outside.”
