What are the technical difficulties in creating a maser capable of inducing the Havana syndrome?

No. Those are kill you properly dead power supplies. Serious internal tissue damage. No point trying CPR. He’s dead Jim.

The dangerous ultraviolet waves – UV C at below about 280 nm – are blocked by most glass and plastic. I know – it’s part of my business to find things that will transmit those rays. Unless your tube is made of fused silica, it’s almost certainly blocking the dangerous part of the ultraviolet.

(Of course, there are still effects from wavelengths longer than 290 but shorter than the visible, and many people advocate avoiding such wavelengths where possible. You can still get a suntan through window glass, after all. )

I’m a ham radio operator and some (usually older) hams refurbish and operate old tube radios and amplifiers. They have a saying you see on tshirts and stuff. “Real radios can kill you.”

My brother was a Radio Officer on ships back in the 70s. He has a scar on his hand from an RF spark that got him in the Radio room.

He also had to regularly clear dead seagulls from the RADAR scanner mast.

Full redacted report:

Big problems with the Mysterious Sonic Weapon theory remain, apart from the lack of evidence any such device(s) exist and are capable of the claimed effects.

Why target diplomats, especially when your own personnel in the U.S. would be vulnerable to retaliation? Why would the American intelligence community refute the theory?

As noted in a previous post, there are better, much more believable explanations.

“The news that the Pentagon is continuing to study the issue comes after most intelligence agencies concluded in a comprehensive investigation led by the ODNI released Wednesday that it is “very unlikely” a foreign adversary using a weapon was responsible for the incidents.”

And the US government and its various agencies have come up with all sorts of crazy ideas, with the word “might” attached to them. “You might be able to make people untraceably sick using electromagnetism” is a lot less kooky than “you might be able to turn agents into psychics by dosing them with LSD”.
