    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: https://soundcloud.com/user-493247881/the-sound-in-havana

    If your not familiar with the story, here is a news report: https://apnews.com/88bb914f8b284088bce48e54f6736d84

    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.

    Sounds like Winlink interference 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.

    Very high frequency sound to my ears.

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