Abstract : Three models of the ADM Receiver/Transmitter have been assembled. One of these units completed the room temperature performance test, except for a few of the auxiliary modes of operation. A second unit is almost ready to start testing. Some further modifications were made in hybrid circuits to correct problems found in the R/T testing and in temperature tests of individual modules. The first Vehicular Applique and Power Amplifier have been assembled and tested with a R/T. The first two Vehicular Antenna Couplers have been assembled and the vendor is completing fabrication on the radiator for the vehicular antenna. The Aircraft Applique design has been completed, and printed circuit boards have been fabricated. Assembly of the first applique is proceeding. Both the final Reliability Prediction and Math Model Report and the final Failure Mode Effects and Criticality Analysis have been completed. The Value Engineering Studies were also completed, and the final report is being prepared.
