Abstract:

The report presents the results of a 4-14-year investigation on military quartz crystal units in the HC-6U enclosure which have been stored under moderate climatic environmental conditions. Crystal units being reported upon operated on their fundamental, third and fifth overtone modes and covered the frequency range of 4.3 to 100.0 MHz. Data on crystal aging and changes in resistance are discussed. Apparent manufacturing defects which result in crystal unit failures are explained. Author
