The high reject problem due to sharp resistance peaks over the temp. run -55 C to 90 C, was reduced to a minimum, probably less than 10. The sample groups in all frequency ranges 150 mc, 162 mc, 174 mc, 188 ,c and 200,c in both cultured and natural quartz were completed and submitted for testing to Victor Electronics Systems Company. Pre pilot runs on all frequencies were made using the latest techniques developed during the production engineering measure. Author
