(I haven't seen every Harvey video, so I haven't looked at all situations in which he communicates to Courtney and crew.)
I have read on voice-to-skull technology and there are many YouTube videos made by those targeted with this tech. This is the first thing I would think about if a "voice" from outside my body started talking to me. In many instances, it is targeted directly at a specific person and no one else around can hear the voice.
But perhaps there is a version of voice-to-skull that gets transmitted to a small area and everyone in the area gets to hear the "voice." Perhaps this is why they usually have to meet Harvey at a deserted beach late at night when no one else is around. Maybe Courtney should demand to meet Harvey inside a cave or some other area that is RF shielded (assuming it is a RF tech, not sure).
Voice-to-skull is one of those technologies that was mentioned pre 2020 (5g as well) and then it is like it was intentionally never mentioned again. They probably know that anyone involved with these techs is going down for crimes against humanity.
It seems most likely to me Harvey is voice-to-skull operated by humans involved in the current transition of our society. I am not against the message from Harvey, in fact, I'm all for Harveys latest message. I just don't like my people getting tricked.
Just my 2 cents about this "VOICE TO SKULL" or "VOICE OF GOD" technology:
* It exists since the 60's or 70's and it got better and better and much better with time. I wonder where they are at today. Long time ago it would look like a rifle with a thicker tip and you had to be close to your target. Like in a mini-van or in an apartment in front of your target.
* Maybe it is very different now. MAYBE THEY CAN USE H.A.A.R.P. and reach someone whose DNA or "etheric" signature they have on record... or someone who has taken the COVID jab?
* This tech. was mainly used to control schizos and MK-Ultra subjects. The target needs to believe it is God who is speaking to them. It is perfect for "lone wolf" terrorists and all sorts of crazy schizoid serial killers (many of the famous US serial killers were creations of MK programs). The technology was used to control the perpetrators of many fabricated terror events including school shootings patsies.
* This tech was recently advertised in the mainstream. It might come out soon as a extra toy for game consoles. It could maybe replace earbuds in the near future. But if they release it in the mainstream people will know and they will not be able to continue to use it for dark ops.
