Well done.
At last we can converse with the dolphins who may listen to us, instead
of our wives who rarely do!
The understanding will probably be the same level, but our hope
may be higher.

Subject: [PSUBS-MAILIST] milestone reached
To all:
A milestone has just been reached in the quest for underwater voice
communications. A special underwater speaker comprised of a tranducer for solids
has been made that so far looks as if it can be lowered the 500' we are looking
for. The goal was to be able to talk boat to boat while both are submerged at
150' deep and 150' apart.
Although it is not intended to function down to the full 500', it must
withstand the pressure this far down and come up shallower and still work
reliably.
Frank D. is building a pressure chamber and will test this speaker once
further testing is completed here in TN. This initial underwater speaker is a
key component to Franks passive sonar/underwater communications console.
Other simular communications system are presently under
construction with completions and installs soon to follow.
