Man! This brings back memories! I actually spear-headed a project about 20 years ago that started with someone causing malicious interference on the US 2m 144 MHz Amateur band. It'd gotten pretty bad. The breaking point was when they started causing interference on the Public Safety bands. I'd built a Doppler RDF device and we actually used a set of 4 high speed RF switching diodes to do the antenna rotations for us. I can't recall off the top of my head, the actual wavelength spacing of the array, and I dunno why I'm thinking it was either 3/4 or a 1/2 wavelength spacing. Don't quote me on that though. But, it was really neat to turn the car around and the LEDs would change position to point us in the right direction of the signal. Good to see that young people are still into these fascinating hobbies! 73 de AK4FM
THIS is how you do an SDR presentation. Explain what it is, give interesting examples and show how to do it. Unlike other videos where people just stand there with their SDR and tell you about all the cool stuff you can do with them. I'm going to check if this guy has written any books on the subject. I wish I could sit down with him for a couple of hours and learn from him. SDR's aren't exactly plug-and-play. I've been into SDR for a while now and the learning curve is steep, even though I am an EE with a lot of RF experience.
If you still find SDR interesting, consider reaching out to the guy. The world is smaller than you think, and paying a consultation fee makes it even smaller
I love how completely happy he is talking about letting his PHD slide, and its because he has a passion for what hes doing now lol. Most people would be tripping about the phd thing I think
12:00 - Every once in a while, I get something right because I actually know about it and it makes me so happy. The moment he played that noise, I said out loud, "That's a digital pager transmission." When he confirmed it, I said, "Awww yeah."
The trouble with SDR is that there's just so much you do, that it's akin to drinking out of a fire hose. That said, it's a lot of fun and a great learning experience. This presentation is fantastic!
I don't wish to give nefarious hackers any ideas, but he mentioned that to damage a TWTA you need some pretty serious gear, but what if you were to override the feedback signal? You wouldn't need a very strong transmitter to do that, and you'd be saying to the official transmitter "MORE POWER!". Looking forward to getting a duplex SDR once this new project comes out. At the moment I'm just learning with my R820T.
***** i guess you could put the incoming data into gnu radio software and make a little program that spits out the data to a screen and you would see the hex data in text format then its up to you to decrypt it haha
My gawd man, whenever do you have time for pron? I just woke up and crawled out from under a rock, and only familiar with the acronym and my vivid imagination's interpretation of SDR + now I'm an hour in, got you at 1.5 speed absolutely fascinated by your passionate presentation, congrats that you found your calling, THANK YOU for Sharing!

Fellow radio enthusiast here....overall, great stuff. Could have not flashed slides at us though, so as to save on having to hit pause...which of course wasn't an option for attendees. Thanks for posting---cheers.
That DF antenna array looks a lot like the _"LoJack"_ stolen car finder that many police agencies (at least here in Southern California) use. If I remember correctly, there is one antenna in the center and four at 90 degrees around a circle.
It cracks me up when a room full of hackers cannot get simple stuff to work. It proves they are human like the rest of us. I just ordered SDR from eBay for the incredible sum of just over £5.

The fast track could cost someone a lot of money if you just keep transmitting their ID all day long. Or get them speeding tickets if you know when they get on the toll road and submit their ID at an exit a few minutes later. At least the PA toll road going to Allentown used to send out tickets to cars reaching the exit too fast. Maybe even get truckers for driving too many hours? The options are endless.These radios can also be used to get unlock codes for cars. Jam the signal while intersepting the lock code sent to the car and when the person presses the button again you repeat the first lock code and hold on to the second one use to unlock the car once they walk away. for newer cars where they are time stamped proximity based ones you boost the signal to wherever the person is back to their car a few blocks away to unlock it.

There are so much software and hardware available if you wanna mess with SDR, and in so much price ranges. I read that the HackRF One from great Scott's gadgets is good for beginners. It covers a large frequency range (1Mhz to 6Ghz if I'm correct), and it's affordable, compared to other RF transceivers (about $200 for the official one, but since it's open source, I'm sure you can find unofficial copies even cheaper). Plus, it's compatible with GNU Radio and most radio softwares. I'm planning on buying a HackRF as soon as I have some money c:
What if we could combine the 3 types of modulation into a single one, with no interference. Then theoretically we could transmit a shitload of data really fast.
@@kornbread5359 - First: clever choice of name. Second: You are on the right track - I recall reading an article describing a similar technique being used in a somewhat novel RF transciever. I'll summarize briefly, as I can't find the article (maybe you'll have better luck?). A major constraint on bandwidth is frequency space - if one guy is talking on a channel, others can't be, so it becomes a competition. RF antennas, as conventionally designed, are receiving (interacting with/modulating in accordance to) the electric charge component of the transmitted signal. However, electromagnetic signals are electromagnetic - they have both an oscillation in electrical and in magnetic field. The magnetic portion of the signal reflects information content of the electric, however it is out of phase with the electric portion by some offset, determined by the transmitting antennas design. What was realized is that an antenna circuit could be designed to capture both the electric and magnetic state simultaneously, allowing that offset to be measured in real time. Simultaneously, they designed an antenna where the offset could be tuned. This means that (potentially in combination with techniques such as mimo) multiple devices could be transmitting on the same frequency at the same time, without use of time division, and the individual signals could be isolated. Potentially thousands of signals (or more) could be overlapped on the same carrier. ... I really wish I could remember the insititute name, because I'd love to know how that's progressing.

Hey buddy. Quick question… There’s a frequency in my home that sounds like uhf or vhf that is either somehow about to read my mind or hear the low waves of me thinking out aloud. Have you ever heard of this and any idea on how to combat such a thing? Thanks.
They often do. But you are inside a metal tube (not exactly a Faraday cage, but still more opaque to RF than, say, your flat), so the very weak GNSS signal may not be picked up well by your phone's receiver. If you use a bluetooth external GNSS receiver, and you push it up against the window, you can probably get decent signal. BTW, that's also the reason GPS doesn't work underwater.
Civilian GPS is automatically disabled for any device that’s traveling over 1200mph, or is above 59,000ft. It’s to prevent it from being used by rogue/unsanctioned ballistic missiles. It wouldn’t be relevant on a commercial aircraft, but still fun.
I like the people on youtube tht buy a SDR dongle know nothing about computers and make a video saying how they know how to do all this stuff not realizing you need a BS and hundreds of hours of time to do this stuff.
What can a simple person buy to stop/block hackers from blocking TV signal radio signals cellphone signals with this tech??? 14 months now I have no communication from own home...no thanks to this. Tech.
Renee Dole Finley Besides a tall pole with great directionality, getting relevant authorities to identify disturbing transmitters blocking your reception is probably your best bet.
The speaker needs to learn about microphones. Sheesh! 6:12 He should have left the mics alone!! He's a sophisticated hacker....and he can't deal with modern podium mics? So - today's lesson: 'Some hackers are idiots'. Thank you. Good night.
Awesome Presentation. that rainbow effect as you called it @51mins looks to me as a cemtrailing plane. (they spray the sky with chemicals and it looks like lines across the sky. This is happening all over the world.
Forced me to look up 'cemtrailing plane'. I had no idea people could believe such nonsence. I feel very sorry for you 'Sir'. Here is hoping you are not late for school tomorrow.
Perhaps the government should also ban locksmiths? Or perhaps the gov should insist on people and companies secure their shit properly. You can't ban these devices because even if you did, there's still electronics outlets to make them and criminals will do just that. By banning it you just sweep the problem under the carpet where criminals can better hide. It's highly small minded of you to call "ban it". Unless you're a criminal trying to stay covered and not have these security lapses found and fixed?
they're passive (listen-only) devices. As long as you're only receiving and not transmitting, there's nothing wrong with that. I mean, the radio waves are willfully being transmitted out, and technically are 'trespassing' onto the listening device, and unencrypted at that. So yeah.
Problems with projector are solved at 6:00 (the talk doesnt start until then). Awesome talk!

Convention about making technology do what you want continues to have audio/video problems always makes me laugh
They just don't care enough, they hacked it all together 😂
Its like when you're doing calculus that you forget how to do the simple stuff
