Re: [PSUBS-MAILIST] Underwater communications

I think the only issue that you might experience in regards to that working is one, the microphones ability to pick up the ultra low frequencies that would have to be transmitted. And then also, you would have to factor in subterranean  and ocean sounds that also resonate on those frequencies and then have a computer try to calculate what is being transmitted versus what is just being picked up by the hydrophone. Those seem to be the biggest issues I see facing such a system. Well and then besides having the frequency change happen on the fly, not to sure how well that would happen, I would be more sure about recording, transforming, then transmitting. Any other thoughts?

Hi guys. I know absolutely nothing about radios, but I did have a few thoughts. Whales can communicate vast distances, using very low frequency sounds. Would it be possible to have a computer change voice into low frequency transmissions, and then have a microphone pick up the sounds, and another computer turn it back into voice ? Wouldn't it be good to be able to talk with someone 25 miles away while submerged ? Whales do it !   Seems like a bright programmer would be able to write up a software program that could do this, and put it on a disk that we could load on a lap top, hook up an underwater speaker and microphone, and everyone would be able to talk to each other while submerged or on the surface.
