Hi Jay, I not verse in morse code, and wouldn't need to with the system set up so the soft TDD systems talk to each other and then put the typed words up on your laptop monitor or the TDD systems screen in the sub(s) and on the surface boat(s). At one point David was saying he could sent and receive a single tone much more easily and at longer distances then a speaking voice. I just needed a unit that could send and recieve the morse tones and convert them to letters, numbers, and what not for text communication. A type of instant messanger service. With the voice command options more available for converting are voice to text. That might work well for are applications so we don't even need to type. I know a Doctor that uses Dragon NaturallySpeaking software, and was able to have the software learn to recognize his voice. "Dragon NaturallySpeaking 10 - Turn Talk into TypeMost people speak over 120 words per minute but type less than 40 words per minute. What if you could create email, documents and spreadsheets simply by speaking? What if you could control your PC just by talking to it, starting programs, using menus, surfing the web?Turn your voice into text three times faster than most people type with up to 99% accuracy. It’s so easy, you can use it right out of the box. It learns to recognize your voice instantly and continually improves the more you use it. http://www.nuance.com/talk/ Then with the text to voice software options you won't even need to read the text coming in if you don't wish to. http://www.naturalreaders.com/ I don't know how different the Baudot code bits are then Morse for being able to be sent out from are underwater speakers, and then recieved by the underwater mics. Perhaps the baud speed would need to be slowed down some. "For the first half of the twentieth century, the majority of high-speed international communication was conducted in Morse code, using telegraph lines, undersea cables, and radio circuits. However, the variable length of the Morse characters made it hard to adapt to automated circuits, so for most electronic communication it has been replaced by machine readable formats, such as Baudot code and ASCII." http://en.wikipedia.org/wiki/Morse_code http://en.wikipedia.org/wiki/Baudot_code "This is a hardware module with a software that can communicate with TDD (telecommunication device for the deaf) in Baudot language at a speed of 45 bauds (standard for America) or at 50 bauds (standard for Europe)." http://www.auristar.com/en/products.htm http://en.wikipedia.org/wiki/Telecommunications_devices_for_the_deaf http://en.wikipedia.org/wiki/Telecommunications_Relay_Service Some TTY (telephone typewriter or teletypewriter) unit options. http://www.hellodirect.com/hellodirect/Shop?DSP=70000&isautosearch=true&keyword=tty&searchCategory=260&searchtype=all&wildcardtype=right&keyword=tty&actn=addkeycodesearch&actwhennew=true&cgychildren=true&keycode=53400563&cm_mmc=Google-_-MISC-_-TTYphones-_-tdd Regards, Szybowski From: cheneharmonieux@hotmail.com To: personal_submersibles@psubs.org Subject: RE: [PSUBS-MAILIST] Baudot's code underwater communication system? Date: Mon, 19 Jan 2009 01:59:54 +0000 It could be useful for the few who only want to keep a contact with a surface boat and not necessarily communicate with everyone... Following this, Baudot's code or Morse code doesnt matter, priority is the communication. For my needs it would be enough, but I'm agree that a fully internationnal or voice system as David is working on stays the best. That's why we are all fingers crossed.

It has been dropped as a requirement use (better methods of communication available) and Ham radio operators no longer have to memorize it for licensing. You are welcome to install it in your sub but who will you have to communicate with you over the soft TTD system as no one else will have it installed. Nice concept but doesn’t fit well with the size of our subs (unless you are getting Ian’s model). R/J2
