Abstract : The overall Manpack configuration including each major functional assembly (receiver, transmitter, frequency synthesizer, etc.) was reviewed to determine whether this configuration still represents the desired approach. Circuit design in many of the functional areas of the R/T was initiated, including the receiver front-end, frequency synthesizer, transmitter, and Manpack antenna/coupler. Hybridization of the IF amplifier-limiter/discriminator was also started. Tradeoffs on the mechanical design of the manpack were also made. The tradeoffs include various external case configurations (single casting encompassing front, sides, and rear with top and bottom covers; and combination front panel and chassis with five-sided cover) and two internal packaging configurations (printed circuit board vs plug-in modules). Preliminary results of these tradeoffs are shown. Design support studies in the areas of Reliability, Value Engineering, and Life Cycle Costs were initiated.
