Abstract : Research continued in an effort to develop and produce 500 quartz crystal units on frequencies 150 mc, 162 mc, 174 mc, 188 mc and 200 mc using both natural and cultured quartz. The design for the 150 mc frequency was tentatively set. Experiments definitely indicate that a lower equivalent series resistance results from higher polishes. The aging oven is being constructed, and the 150 mc units that are acceptable for resistance will be subjected to the required 30day test. (Author)
