Microwave weapons?

Makes you think who was the source of the whole thing.

Though I find it hard to believe that an embassy would not have some kind of "signals/Tempest" person on staff who would be All. Over. This., it is getting harder to be surprised by incompetence in the US gov't.

It does not surprise me at all.  The US government is incredibly cheap when rent seeking is not involved and doubly so about protecting employees.  I would not say incompetence so much as dysfunctional.  Dysfunctionally incompetent?

That the whole set of incidents were not thoroughly and objectively investigated is damning.  There should have been a positive result one way or another.


--- Quote ---Also, the attack could be intermittent, and directed away from where any fixed sensors or antennas are known to be. For example, if the guys in "the van" know when the RF guy gets in in the morning, or goes out to get coffee, etc, or if the embassy staff are being attacked while at home or out and about, it could be reasonably easy to avoid detection. The obvious countermeasure for this would be for the staffers to wear some kind of RF/ultrasonic-detecting device on their person, like a radiation film badge.

RF at these frequencies bounces very well and the intensity was plenty high so directing it away from possible warning receivers is not practical.  It was the level where even untuned detectors are sensitive enough but they are not useful in a complex RF environment unless you are close to the source.

Send a tech to the affected embassy to setup a remote network addressable spectrum analyser.  You could buy the hardware off the shelf in a couple days for 10s of thousands of dollars although interestingly enough, such hardware is crippled by the federal government's ITAR rules unless you get an exemption.  An electronic warfare receiver might be better but I don't know about pricing and availability on them.  This would not reveal the source but it would definitely show something fishy is going on.

Something else would be needed to test for ultrasound.  You might have to have something made.

rofl I bet you it was a carbon monoxide lead on a shitty cuban boiler, maybe too many people smoking cigars outside the air vent

no one is going to attack a US embassy to give them brain damage, especially on their back yard, Why would putin start a war between cuba and usa? How did cuba afford such technology? they cant even pave their roads.

Embassy attacks happen in the middle east and in Africa, because of religious extremists.

Can someone give me a modulation scheme and power level and frequency required to induce these frey effects so I can try to put the microwave part of this issue to rest if its under 20W and 18GHz?

I can't do anything about the ultrasonics but this honestly kinda sounds like it belongs on infowars.com. ALl these articles are coming up with insane plots with no freaking motive behind them. Russia bribed their way through Cuban officials or Cuban organized crime that runs the imports and outports to smuggle in some kind of high end psychotronic weapon taken out of "red alert 2 yuri's revenge" 50's anti commie pulp, despite the fact that the USA strictly watches the imports to Cuba to determine if you know, someone is trying to put nukes there again, then figure out how to hide or exfiltrate this machine after it causes a media debacle?

If this thing was outside the embassy in a van, the power level should be low, even if it was some whizzbang dish or phased array housed in a non suspicious van (yea right, like vans in front of embassy won't get investigated by the friendly CIA security detail that probably lives in an apartment across the street). These guys are not exactly old ladies which are scared to go outside. You put any large vehical outside an embassy now a days and people start to think its a jihadist with a car bomb. I bet you there is a 50% chance some 'kid' with a boroscope and a skate board is going to probe a van parked outside the CUBAN embassy at night.

Microwave is certainly possible, but may not in China. Most Chinese buildings are made of concrete-rebar structure, and it would be hard to target anyone who's not directly facing a window.
Also, US and China are known for the ongoing spying war from embassies and consulates of each side. It would be stupid not to radio-enforce the buildings.

Unless its a side effect from a espionage device, why would you attack a embassy in the first place? If anything they will just move it to a even more secure location thats more difficult to spy on. They probably spend all this time making local connections in the area so the embassy can be spied on, housing their counterintelligence near by, digging tunnels, etc. You know cuba and china can just tell them to get the fuck out of their country if they wanted to? Or zone that area for some kind of public works that important like some air purifier, water treatment, power station that HAS to be there for the city to function and tell them yea sorry

They would need to fly a drone and attach it to a window or something, if you did it from across the street or a roof top it would be attenuated or freaking demolish everything with seismic waves.

Maybe some kind of vortex cannon could do something like bang on the embassy walls and make people think fidel castro's ghost is banging on the windows. That could explain some symptoms if they use some kinda combustion engine to modulate it, since it would be carbon monoxide there that can poison them if it has open windows or something.


I can conceive trying to send audio this way
Maybe they should investigate the guy making the video, its about at a Cuban technology level, perhaps he did the engineering

If you know someone is a spy and is really being a trouble maker why not just hire some local hoods to stab him ? The article implies they know the identities of the agents, so that means a mugging, beating, stabbing, shooting, poisoning, car accident, fire, drug bust, etc can easily be arranged.
