Convert Radio Waves to Bits (RF Demodulation)

[@SpontaneityJD]

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.

[@SteveKelly]

Really well explained. Production quality was on point too.

[@NateSinger]

Thank you :)

[@chancejohnson384]

That was amazing this gave me such a better understanding of modulation

[@NateSinger]

Glad you got something out of it! :)

[@Gabriel965519437]

Great tools to do some hack and fun projects. Well done!!

[@NateSinger]

Thanks :)

[@ivandemidov4653]

Well explained. Would be really great to see a video about hardware you're using for such tasks.

[@NateSinger]

Good idea, ill add it to the ideas for the series!

[@filipcoja]

really nice and detailed video, was fun to watch

[@NateSinger]

Thanks :)

what's the dB difference between 1 and 0 in qam?

[@habibmohammed2779]

@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]

Are you asking about the hardware itself?

[@habibmohammed2779]

​@@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

[@habibmohammed2779]

@@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!

[@wufei747]

Is there any specific SDR RTL you'd recommend? Love the video, can't wait to see more!

[@NateSinger]

I'd suggest asking these folks: www.reddit.com/r/RTLSDR/

[@mykolasharhan3016]

Thanks for such a great workshop video.

[@aajeev]

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.

[@NateSinger]

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.

[@aajeev]

@@NateSinger awesome thank for getting back. I’ll make sure to link your channel wherever I can.

[@andrewborntrager7909]

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?

[@johnathanhusky2211]

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

[@NateSinger]

Whats the best way to do this?

[@mofaelectronics1295]

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?

[@aussierule]

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?

[@debankagiri9800]

@Nate Can you please provide how can display the magnitude of the signal

[@lindsaytrinder1302]

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

[@SanjayVerma-bc7bs]

how do i encode bits into waves?

[@amitavmitra8888]

Thanks so much for making this video, it was really well done. Learned a lot :)

[@NateSinger]

Happy to hear that!

[@amuga_1]

i love u for this.

[@wrxefx3931]

How do I reach out to you, good sir? I would like to discuss many things.

[@picolopicolo7661]

Hello please is there a software used to show wifi radio waves signals into bits on a smartphone?

[@guillaumeflinois119]

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.

[@NateSinger]

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!

[@OxTongue0]

Thanks for the video

[@Sapphire1721]

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.

[@lindsaytrinder9968]

Can you please let me no the software your using please

[@hoteny]

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.

[@CaTuber]

How about mixing that signal down from baseband down to something that a 20MHz sampling rate makes sense for?

[@NateSinger]

Can you explain this a bit more?

[@jeremylangford4767]

Thank you!!!!!

[@tork9067]

Now i can hack my neighbour car

[@Skeptor505]

You can help me in V2K

[@Usuaurio-kj1ym]

Hello i will try to decode my tpms sensor 433.92mhz signals using arduino but first i replicate you video thanks

[@etcsk8114]

Dear plz try to improve your sounds system

[@ZatoichiRCS]

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.
