    Most probably know that many government employees left Cuba because of loud audible sounds that did brain damage. I think it was acoustic and not RF. Here is a sample that was released but I can't hear it with my hearing...but my wife can:

    If your not familiar with the story, here is a news report:

    Of those who can hear it, what does it sound like...any type of signal? The wife says it sounds like finger nails on a chalkboard?

    If you took a recording of chirping crickets then sped it up five or six times, that's what it sounds like to me.

    Winlink emails going out to every member asking for donations for the "Winlink Defense Fund".

    Reminds me of an instructors hearing aid I had to listen to squealing all day at a training course.

    Curious what frequency it sounds like? I can't hear it, even with hearing aids...:(
