This was a great video, I’ve learnt so much. But if I could provide some feedback, you speak really fast and at times it was very difficult to hear what you were saying - The audio wasn’t the most clear.
hi sometimes we have a rf signal that it's not repeatitive sampling this signals requires a very high samle rate analog to digital converters how can we downconvert this not repeatitive signals and use low sample rate analog to digital converters ? is there anyway?
This is really well done! If I have to say, I feel the pace is some times a bit too fast and voice volume goes up/down quite a bit. Also, I would love if you can also give a run through of the GUN Radio too, I think that software is a beast of a tool to learn. But overall, amazing video, thank you for sharing the knowledge. I was just about to start to get back to it. Also can any of this be done with Windows? Not really a must, but now I have to get ubuntu installed to get back into this.
Glad you enjoyed it and thank you very much for the critique! I'm certianly working on my pace and speech stability, I know theres some improvement to be had there. I'm thankful for the amount of interest on this and there's been enough that I think i'm going to treat this as the first video in a series. Planning to do blackbox bitstream reversing and more videos on RF stuff in general, so definitely more GNU things coming down the pipe. I also will definitely do an OOK modulation video and once I clear some stuff with chrystler I'll probably do a video on abusing the vehicle. All this to say there will be alot more GNU instruction coming down the pipes. You can absolutely do all this in Windows, im just a slut for nix, mostly cause of my work and security background. GNU is available for windows, HackRF has drivers for windows and GQRX is available for windows I believe. Regardless this is just one toolchain, there are a variety of ways to actually do this. Hopefully the principles came through at least.
@Nate_Singer hay, let me say to you that I'm lucky! I did not expect that you are going to use a key fob in your demonstration! I was looking for an explanation of how key fobs actually work and your video helped me a lot! You did decode and demodulate the signal with a couple of programming and tools. But I'm curious to know exactly what happens inside those devices, and how the modulation and demodulation happen between the transmitter and the receiver
@@NateSinger Yes! The electronics! They are complicated and mysterious. only Electrical engineers know how they work and that is frustrating . Thank u for your fast response
@@NateSinger questions i was looking for the whole past night: How a radio wave carries information? and how the receiver device receives that wave and decode it to get the info? after that we have another mysterious story: how does that digital signal mean smth to us? you said it its just an ON OFF!
Hello. When I’m putting sample rate on inspectrum to 20000000 its showing as 10hz. Also when I’m using cursor each gap is a different space so i don’t know where I’m going wrong. Is there a forum or email where i can send some photos and ask for some help. Thanks
This is fascinating! Wonderful explanation and presentation. Liked and subscribed immediately. You just need a little better audio, there was 2 times in the video when I don't know what you said. Please keep making videos. Is there windows based applications that will do the same?
Thanks for the video man, I just wanna make sure I understand before I discover an easier method after: Is there any way to 'capture' my RTF drone feed? I have analogue FPV goggles with an antenna along with a simple analogue drone that has a camera. My goggles don't have a USB out to monitor or PC just for someone else to watch. So I was wondering if there was any way to use this demodulation method to capture the drone feed and display it on my laptop(running arch if it helps...btw;) or am I just really looking too deep into how to capture my analogue RC drone cam feed?
Hi, I am very new to all this so maybe my question isn't even relevant but would I be able to use my NRF24L01 with a USB adapter in order to identify the carrier and to capture the signal or must I use something like an osmo SDR dongle? If I can, can you point me in the direction to look for how I can do so, please? Thank you very much for the video it is incredibly helpful and well made.
Google RTLSDR BLOG V3. It looks like the device you have is a fixed freq so it won’t work. The RTL is only 30 bucks and is your best low budget option. Thanks for the review!
I am more curious about how things are in sync tbh. Even if we have a clock like quartz ones, they are not perfect. I bet some crazy synchronization logic exists that I don’t know about.
Interesting that one can use the tools knowing absolutely nothing or should I give credit and say no mathematics is shared to justify the use. What could have been a top tier video is nothing if it’s possibility.
Please do more on this subject or on radio waves in general. This stuff is incredibly fascinating. And your way of explaining is much appreciated.
Really well explained. Production quality was on point too.
Thank you :)
what's the dB difference between 1 and 0 in qam?
That was amazing this gave me such a better understanding of modulation
Glad you got something out of it! :)

Great tools to do some hack and fun projects. Well done!!
Thanks :)
Taking the DFT of the raw data is another way to find out the carrier frequency instead of searching, assuming the sample rate is fast enough
Whats the best way to do this?
Well explained. Would be really great to see a video about hardware you're using for such tasks.
Good idea, ill add it to the ideas for the series!
really nice and detailed video, was fun to watch
Thanks :)

Is there any specific SDR RTL you'd recommend?
Love the video, can't wait to see more!
I'd suggest asking these folks: www.reddit.com/r/RTLSDR/

@@NateSinger awesome thank for getting back. I’ll make sure to link your channel wherever I can.
@Nate Can you please provide how can display the magnitude of the signal

how do i encode bits into waves?

Hello please is there a software used to show wifi radio waves signals into bits on a smartphone?
i love u for this.

Now i can hack my neighbour car
Thanks for the video
Thanks so much for making this video, it was really well done. Learned a lot :)
Happy to hear that!
Can you please let me no the software your using please
Thank you!!!!!
How about mixing that signal down from baseband down to something that a 20MHz sampling rate makes sense for?
Can you explain this a bit more?
Hello i will try to decode my tpms sensor 433.92mhz signals using arduino but first i replicate you video thanks
Dear plz try to improve your sounds system
You can help me in V2K
