Abstract : The major effort was in design finalization of the exploratory model system based on the results of breadboard circuit evaluation and testing. PC card layout for the R-T was nearly completed and many designs have been fabricated prior to parts assembly. PC cards fabricated and/or assembled are the power supply, RF tuner, synthesizer and frequency control, power amplifier and harmonic filter, and the RF network and detector cards. The mechanical design for the exploratory models is nearly complete and the long lead items are on order. Redesign of key items such as that of the airframe applique to simplify manufacture has been performed. Circuits and designs test data are supplied for the most significant accomplishments during the report period.
