Cliff, Go to "projects and photos" section of the web site and Select Doug Jackson and proceed to his page, then, select submarine and go lower and select hydrophone. I think he has quite a collection of recent testing and result videos and pictures that even cover how-to-build presentations. You will probably still go with the OTC system you located as the range you can achieve is a bit shorter, but this gives you a good idea of where we are now with our basic broadband voice communications consoles. You have a really great looking sub by the way!

Do you have a link? The equipment I am looking at is the same that is on Dan Lance' boat. The manufacture is Ocean Technology Systems (OTS). The equipment I am looking at is: STX-101 surface transceiver, 4 stations www.oceantechnologysystems.com/stx_101.shtml SSB - 2010 transceiver - 4 channel diver unit www.oceantechnologysystems.com/ssb_2010.shtml Cdk-6 Surface Accessory Kit, Surface Unit conversion www.oceantechnologysystems.com/cdk_6.shtml Details of these units are at the links given. The goal is to have UWC between my sub and a base station and be able to communicate at 1000 m. With cost of the equipment is $3300. The STX is the base station and the SSB-2010 is a diver unit that can be converted for sub use by the Cdk-6 unit. How far along on the development are we? Can you send me anything I could read to come up to speed on both the sonar system and UWC you have developed?

We are soon going to modify it to transmit as well and I would love to make a very small system for your sub. His system will be the first to better make use of the higher transmition levels the voice transmitter can accommodate. Ranges with high reliability should be around 700 feet apart and 500 feet deep using this simple system. Describe if you will the expected performance goals you anticipate from your OTC system and the projected cost estimates. The more systems we can make available to these builders, the better for safety.

I have a pinger attached to the boat so finding the boat should not be an issue. What I really need on the boat is the underwater comms. Dan Lance put me on to some really good equipment from OTS that I am looking at.

Hi, Cliff - nice to see the progress on your sub. That is one beautiful boat!!
I have a thought about your lines. Since you're in really poor vis would it be prudent to keep your locating line, but, keep it buoyed by intermittent floats along the rope? This is a buoy system we use up here that keeps lines off the bottom. Whether it would be practical as far as your intakes are concerned is another matter, but, it may just save your bacon.
