Abstract : The design for the 150 mc quatz crystal was confirmed by processing a separate batch of units. These were produced at a satsfactory yield through the finishing operation. An aging oven and associated oscillator were built and tested. Some 150 mc units were aged 14 days at 85 C, pat of which were satisfatory, and part not. Extrapolating to 30 days is difficult, but it appears the yield will be about 50%. (Author)
