Abstract : The results of experimental work concerned with the 70 mc group of crystals are discussed. Emphasis is placed upon the problem areas encountered in this study: the erratic behavior of the motional resistance of the crystal units and the problems encountered in trying to measure accurately the resonant frequency of unplated crystal blanks. The methods and equipments which are being used to resolve these difficulties in the 90 mc study are discussed in detail. (Author)
