what year is that?

lol my typo 🗿

Youve made some pretty good conclusions man. Love the effort.

Mario music faintly in the background... airship music I think. Someone playing Super Mario Galaxy in the background?

So, I know you said this is the final part. But are you sure the RF signal is coming over the power lines? I'd think the variac would have filtered most of that out. Either way, it would be interesting to see if you could still see the signal if you powered it through a simple RC low pass filter.

What Linux distro are you using?

Check "Analysis of Compromising Video Disturbances through Power Line" paper, they research exactly this phenomenon.

That wide hump on the SDR is almost definitely your signal though! It's very wide bandwidth and significantly above the noise floor, so it could carry the NTSC data. Maybe you can somehow view the information contained in the signal by applying an analog broadcast TV demodulator (though the RTL-SDR may not have enough bandwidth sadly). Iirc analog TV broadcasts were just very high bandwidth AM transmissions (since it's AM, the peak you see could be real and not an artifact since it functions as a carrier (probably related to the video signal clock frequency if it is a real signal playing a role in transmission)) with a bandwidth of 6MHz to transmit all the video data. I still have no idea how a digital signal from HDMI/displayport is being converted and modulated to a format that the TV understands and demodulates to an NTSC signal. On an earlier video, I said that maybe it has to do with the monitor's internal circuitry converting the digital signal to an image on the panel where the EMI from addressing the pixels just happens to be similar to AM modulated NTSC.

The reason you hear a tone with DSB (or LSB/USB) is that the frequencies in the signal you receive are going to be shifted down in frequency with the center frequency at 0Hz. For example, you'll hear a 1kHz tone if your center frequency is at 500.000MHz and there's a peak at 500.001MHz (or 499.999MHz since DSB is symmetrical). Some SDRs have artifact peaks like that though that aren't real signals, and since that signal is very narrow and at a single frequency, it may not contain any useful information (if it's an artifact) so it may not be the signal that's causing the TV to display you monitor's output.

First! Hmm...

I know what this is. Have you seen the movie, "Poltergeist"? 😂

Neat find. Hopefully, it works a little better with headphones (many pocket radios use the headphone cord as an antenna). Be sure to remove those Leakacell batteries before too much longer! I’ve had Duracell AAs leak after only 8 months or less in use. That’s weird that some stations transmit mono music in stereo. FM radio is supposed to be getting more popular than AM, so I would have thought FM stations would make more effort to have more modernized equipment.

you should take an electronics class. this is pretty standard stuff...

Looks like a vinyl record!!!

The forbidden „cd”

Funky frog

POV: me 1995, Frankenstein my old broken floppy to a working one

Neat!

what desktop environment were you using on your linux machine? i really liked the taskbar! also what distro?

That poor computer

you used windows not winows!

try lego island!

Internet Explorer still being in Windows 11 is peak Microsoft

isn't bonzi buddy a virus file ?

I know a guy selling a bridge.

This, combined with the pc component vibration listening thing. They've literally got it all.

yo creo que lo que sucede es que se va de forma analógica a través de la toma eléctrica, se me hace que es eso

In the second grade a long time ago. I turned on my black and white dial TV in my bedroom with my brother and we were able to listen in on my moms telephone calls. It worked for a while until it eventually didn't or I never could set it up correctly again.

I read somewhere that tvs will attempt to display any analog signal its being fed...

Hitachi?? 🧐

I feel like this is forbidden info, as this has most likely already been discovered and exploited by certain government agencies awhile ago. Now please excuse me while i cover my entire room in tinfoil

very brry good video! :)

People think their crypto/passwords are safe due to network encryption, but they never saw me watching their unshielded displays coming!

My old radio used to pick up the audio of whatever my neighbours used to play on their television via dish television connection.

I hope you all enjoyed the video. It was a lot of fun to make.

so my neighbors can see me watching corn by using their 80s hitachi tv... I knew I wasn't hallucinating

The humming level in that room is very unhealthy. Fix that ASAP if you spend a lot of time in there.

So.....When Doom?

Was really windy that day you recorded?

Hitachi? Same brand as my grandma's massager 😊

can you watch shazam on it through another time dimension/blackhole?

Lets see nordvpn protect against this.

Your videos and the comments have given me a lot to think about.

Hi! I study electrical engineering. This phenomenon is called Van Eck Phreaking and I don't really remember it well so I'll just leave you to do some research on your own as I don't wanna spread misinformation

Meanwhile the FBI in a van outside your house. No need for warrants or anything apparently…

you found the NSA frequency good job

animal crossing music :D

Downloading this video

Very interesting! Thanks for the video mate. There's a type of cyber attack now that does something similar with radiation from HDMI cables. Although I think AI is involved with that one. Google it and you can find out more.
