The HLF-3 acoustic source was refurbished and the calibration verified at the NUSC Seneca Lake facility, in preparation for the 1978 Summer Operations aboard the USNS Lynch. Refurbishment consisted of a redesigned Wetside Electronics package to improve reliability and serviceability, and design improvements to the pistons, motor mounts and suction strainers. Calibration was required to verify the source performance and identify any gain changes that may have occurred during the electronic redesign. Author
