    Hiya,

    Hopefully this is the right place to ask. But I have a problem with birds
    and have been told that a ultrasonic sounder operating at the right
    frequency should deter them and be inaudiable to humans. I've been told
    it's simple to built, all I need is a 100w piezo and a +-300w squarewave
    driver and run it at >20khz Now, this all sounds a bit greek to me, but
    could someone here shed some light on what I need (In english) and even
    better - Places to buy it in the UK and then build it. I know I'm asking a
    lot, but I can't pay out over £400 to buy a fancy indistrial one...

    Cheers.
    Dan
