    HI ALL
    For the last few months i have been designing low frequency video link for under water as you all know high frequency RF does not get through water very well, took video link down to local canal to try video link under water as the last time i took this out to try it did not seem to work very well back to the drawing board start again. But this time it worked receiving antenna was plugged in to receiver and that was plugged in to LCD screen so Pauline could watch it in the car, i walked away with TX antenna in the water transmitter and camera i was holding in my hands and i would say i was about 500 foot away and Pauline was still watching the picture in the car but picture did go to black and white at that distance but i don't think that is bad at all

    Have been looking in to doing sonic radio link for under water, one of the benefits in doing this is you will be able to use the system in salt water and not have to worry about range problems under water as this will open up a new world in controlling model subs under water from what i am seeing coming back from playing around with this system i can not see why you would not be able to go down to 450FT of depth i know what you are thinking there is not a sub that can go that deep but the system might soon be in place to be able to go there
