Abstract : Accurate measurements of effective resistance were attained at the 2-microwatt drive level by making minor modifications to the TS-330(AGC) test set to permit it to function as a 'Transmission line' circuit. These more accurate measurements disclosed that there were problems in meeting the 1,000,000 Q at the 5-Mc level as well as at the 1-Mc level, where several mounting arrangements had been evaluated without success. The various mounting arrangements are described, as well as the current approaches which involve attainment of higher Q levels by the quartz resonators themselves, rather than complete dependence on the mounting arrangements.
