Abstract : The report describes the design of the receiver/transmitter circuitry and the preliminary mechanical designs which have been accomplished for the receiver/transmitter structure and circuit modules. Much of the circuit design and fabrication and testing of many of the hybrids were completed during this report period. A major portion of the R/T mechanical design layout was also completed. A detailed internal mockup was fabricated. This mockup is used to define and facilitate the module design and cabling. The deliverable mockups for each of the AN/URC-78 system components were completed. The initial Life Cycle Cost Study was completed in detail, including a production estimate. Considerable analysis was performed on reliability and maintenance requirements. Value Engineering effort continued in several key areas and substantial savings have been achieved. A review of the nuclear hardening design aspects was completed; the results are reflected in the nuclear hardening supplement to the Design Plan.
