RE: [PSUBS-MAILIST] Passive sonar

["David Bartsch" <dbartsch2236@hotmail.com>]

Gene,

  All hydrophones have been installed in the array and have been tested 
fine. Installing "new" junction box following interface cable construction 
onto Hydrophone Selector Unit (HSU) completed. This new install should allow 
for farther spacing between array assembly and pream/amp console.
  Actual in water performance testing probably not until next Spring 
(2008). Must intall pier mount or aboard small surface craft. Results will 
follow once completed.
                                                                            
         David
