Brent,
You don’t have to try to convince me, we been done this
road at great length already just a short time ago on the list. I have Dragon
NaturallySpeaking and you will find it needs optimum conditions to perform, a
high powered PC, and still leaves something to be desired…most reviews
will show that it doesn’t make the 99% claim. It is good but PSUBs isn’t
the application for Dragon. Please consider the simple solution first and also
who else is going to carry a corresponding transceiver?
It was concluded by others here that plain voice comms would
meet the needs of almost all cases that a PSUBBER would encounter.

system?
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 Type
Most 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.

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.

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)."

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.

Brent,
We have already hashed this out; Morse Code is really
impractical for our situation. Besides you will not be able to find
anyone who knows it anymore. 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).

Hi Thierry,
I think you might of found the link we were
missing. That soft TTD system is very interesting. I hope this
group can figure out a good Morse Code unit. That is one of
they types of communication systems I want on my subs and support boats.
I'll have to order a pair of those units and try them out.

Hi everybody,
On my side, I was reading the mailing list archives while a saw a
conversation on last February about underwater communication system using
Morse code. As a scout, I've been interrested because we do use it in
games. But as a professionnal, I'm a sign language translator for deaf persons
and my wife is deaf herself. Perhaps you know about deaf community, the
point is that a tele-typeywriter(tty) is using Baudot code (http://en.wikipedia.org/wiki/Baudot_code) So
I asked myself if we could use a TTY/TDD as a
single or dual frequency transmission. It could have greater range than plain
broadband, according to David.
Physically, the transmitter/receiver (the TTY itself) do already exist
and using it in underwater communication could be and interresting
application of that. There's also softwares that convert any computer into
a TTY... In fact two ingeneers from Quebec built a system called SoftTDD
and I do use it at home so my computer became a TTY but at
a really cheaper price (325$ CAN.) Have a look at http://www.auristar.com/en/ .
I have also read about CallTTY/TDD software 2.0. but I dont know about
it...
Well, I should buy "Electronic for dummies" and start working on
that, but I share with you this idea wishing it could
works and interrest someone! What is your opinion?
