DIY Underwater Voice Communications Part 1

Presented by SubmarineBoat.com. This is the first in a planned series of videos that will cover building your own broad band underwater voice communications system for submarines and scuba divers. In other words, we want to put speakers in the water so anyone near can hear and a submarine or diver at depth with a hydrophone can listen and then broad cast back using their own speaker. So we intend to show the construction of an underwater speaker and hydrophone and build or adapt the required electronics, which are mainly fairly common amplifiers. Our designer is David Bartsch who spent eight years in the Navy and made thirteen deterrent patrols aboard the ballistic missile submarine USS Kamehameha (SSBN642B) as a sonar technician.
