"Sonic attack" may have been two ultrasonic signals accidentally interfering
Is it not equally likely that the source of high intensity, high frequency RF modulation lies inside the US communications infrastructure associated with an Embassy inside a declared enemy state? I.E. the reason there is no external source, is that it was a product of faulty US SIGINT in the first place.<p>Is Guantanamo Bay reachable by microwave link from Havana? Day traders prefer RF to complex internet routes, if they can show speed advantages. Direct RF might have some SIGINT advantage over other choices here, to talk between US assets in the economy.<p>I&#x27;m not a cuban or a russian, and nobody pays me for my opinions btw. I just find it strange everyone externalises the source, when we probably all believe the investment the US makes inside its own communications is actually sufficiently at scale to be the source of the problem.
