Test of Model LJ Aircraft Crystal Frequency Indicator (Type CHS-74015) Serial No. 11

Abstract

The mechanical features and workmanship were checked by careful inspection. The Model LJ equipment was set up with the RU-2 and RU-3 receiver to check its operating characteristics. The electrical characteristics were checked by measurements in the Laboratory. Temperature frequency characteristic data were taken of the self oscillator and the ten crystal over the range from -30 degrees C to 50 degrees C. The equipment was then taken to the Naval Air Station installed in the XRE-1 Bellenca cabin plane no. 8938 and tests were conducted under actual flight operating conditions.
