and therefore I'm one of the most people. I do realize ELF & VLF ain't microwaves but I think it is somewhat related compared to other articles. point is - someone is blasting constant speech straight to heads of population and nobody is willing to do anything about it. it's 21st century yet the world we live in has gone back to Dachau methods.

There is no mechanism by which ELF or VLF could be accidentally received without physically large antennas, or very fancy signal processing. The wavelengths are just too long, VLF is 10-100km and ELF is longer. The slopes are just imperceptible. Imagine trying to notice a wave in water that's 10 km long (and not very tall). You cannot even transmit speech with ELF, it carries information so slowly it's only usable for more code or very slow digital signals. Heterodyne systems don't let you pack more information into a lower-frequency signal, they go the other way.

  Sounds like you know a thing or two which is what I appreciate. I don't know what's used and don't have a budget to perform any meaningful analysis. But I do know that GWEN towers are 30 years old tech that's capable of transmitting signal in 200mhz to whatever ghz range 200 miles afar. Frey effect according to wikipedia is audible in 200 mhz - 3 ghz range. According to James C Lin research - signal doesn't have to be strong (in fact, strong signal can get hazardous to health and used like a weapon like in Venezuela operation). Surely radio folks can match up 30 years old tech. And signal processing capabilities nowadays can get absurdly sophisticated.

  What are your thoughts on FMCW radars? "Emotion recognition method using millimetre wave radar based on deep learning" research paper is what I find interesting. There also exists research paper that deals with recognition of drivers behavior (logically meaning - FMCW radars are capable of locking onto moving targets in quite long radius). From what I understood (with my limited understanding of the subject) - such radars are capable of picking up EMG signals. and according to wikipedia - EMG is enough to feed neural networks and decipher so called "silent talk" aka your inner monologue.

    Those operate in the gigahertz ranges. Note that the emotion detection is done by scanning the facial expression, gigahertz range is starting to get pretty close to light, and it penetrates skin to a depth of less than a millimeter, so it can be used to draw pictures.

      Not sure what you mean by "draw pictures". But I would be forever grateful if you could confirm or dismiss technical possibility of scanning EMGs remotely. It seems to be that way to me. At least to some degree which is already sufficient for stuff like neural fingerprinting (yielding individual identification and positioning in radar range) but I do lack understanding of actual physics to assess nature limits. Rest falls into place easily - Frey effect is proven science and NASA decoded EEG signals into words already back in 2003.

        I'd be surprised if it were possible to directly measure muscle activity with millimetre wave radar. It looks like they're detecting motion, which is related to motor activity, of course. EEG "spellers" c. 2000 required a cooperative participant who's actively engaged in a behavioural task: you attend to the letter/word you want to send and thereby produce a different response when it (vs the other letters) flash. Implanted electrodes can do a lot better but it's still not something that will let someone "slurp" your thoughts out of you -- it'd be like subvocalizing them.

        I do believe that signal deciphering part is somewhat solved. All the way up to real-time text stream. You can even go and run it yourself if you want to (e.g. https://github.com/CNN-for-EEG-classification/CNN-EEG https://github.com/CNN-for-EEG-classification/CNN-EEG). What I do struggle to find a proof of is signal gathering part. What do you think of this patent https://patents.google.com/patent/US3951134A/en https://patents.google.com/patent/US3951134A/en ?

  Another paper I find important: https://ieeexplore.ieee.org/document/6711930 https://ieeexplore.ieee.org/document/6711930 What are your thoughts on radiomyography?

    If you have a look at the paper, their antennas are designed to operate between 902-928 MHz, and they test for response at 600MHz-1200MHz, with it attenuating very quickly away from the peak at 900MHz. This is, again, an entirely different thing from VLF and ELF, which operate below 30kHz, at frequencies 20000 times lower.

      Different indeed. Sorry about that - it's just that with voices in head there's barely any other priority in your life. Have a nice day.

Sometimes the brain’s auditory cortex can 'misfire' and create sounds or voices that feel 100% real, even when there's no outside signal. It’s actually a documented medical phenomenon. Comparing this to Dachau suggests you’re feeling a massive amount of psychological pressure. Usually, when the mind is under extreme, prolonged stress, it can start to externalize internal thoughts as voices or 'beamed' messages. It might be worth talking to a professional about the distress this is causing you—they might have ways to help mute those signals.
