To all: On behalf of the entire passive sonar hydrophone research and development team and many silent helpers, Jon has asked that I inform everyone that a new hydrophone has been made that is made from "off the shelf" items, and can be purchased for around $30.00 at almost any hardware store. It is constucted for use down to 500' the maximum depth of most psubs. Pictures of this newest hydrophone are available on the special projects section on the clubs web site. This hydrophone is designed for construction that does not require the use of a machinist lathe. We in this group are attempting to provide the basic components that would be of value to all members be their budget small or large. (something for every one) Details on the amplifier console and how it was made are soon to follow and will also be posted with pics as well. This hydrophone along with other examples and supplies should be at this next convention and the "how to build" instructions will be made available to all interested on the club site. In addition, a simple test sonar unit will be on hand to duplicate Peters' "Kraka" viewport installation on any and all attending submarines! The schematics of how this unit was comprised will be available and will suprise you as to how simple this unit really is. David Bartsch More immediate than e-mail?
