Re: [PSUBS-MAILIST] sonar research

Sounds like a mini-PSUBS conference shaping up in the Bahamas, in the 
spring.

Let's take the shipping issue off-line and into private mail.  Based 
upon what I've read so far, it would seem shipping to Vance makes the 
most sense.  Cost is less for shipping in US, and Vance can either bring 
them to Bahamas for testing, or test them in Florida.  Either way, the 
units get tested and evaluated the way we want.  We'll work out payment 
for shipping.  Perhaps this is a good use of our membership dollars 
since the project will impact the group at large.  I'll coordinate 
between Vance and Les.

Let's also come up with a "test plan" so we all agree what the 
environment should be (depth, distance) and do this testing in a way 
where we can document the results and post them.  Jay and Vance both 
have valuable knowledge and experience, so perhaps after discussing the 
field testing over a bottle of rum (or two), they can provide us a 
summary report including the effectiveness of the units and any 
suggested enhancements or changes that should be incorporated.  Jay? You 
interested in working with me on a test plan?  If so, contact me 
privately so we can put it together and than post it publicly on the 
website.

Another issue that comes to mind is getting the "submersible-based" unit 
down to a significant depth.  I suspect that Les does not have 300-500 
feet of wire attached to his units.  I'll leave it to Jay and Vance to 
figure out what material we will require and how much it will cost.

Someone make sure they bring a camera and document as much as possible.  
It would be great to have this "field test" on the web site so the 
community can get an idea of the work involved.  Make sure you smile, 
but no mooning.  :)

If this topic interests you, and you are not a member of PSUBS, this 
would be a great time to join and help us sponsor projects like this 
one.  If successful, this project will provide a low cost do-it-yourself 
alternative to commercial products for underwater sub-sub and 
sub-surface communications.  Your membership dollars will help make this 
field test a success and also help subsidize other projects in the 
future, maybe even one of yours!  Join PSUBS today at
