100 kHz Crystal for Radio Frequency Calibrators Date Code 8-70 Tested Working

Product DetailsThis is a vintage 100 kHz quartz crystal in a rectangular metal can (likely HC-13/U or similar holder style with wire pins).

Frequency: 100.000 kHz (exact standard for 100 kHz markers)
Markings: 100.000 KC (top), 9142400 CUR (side)
Date Code: 8-70 (August 1970)
Purpose: Used in crystal calibrators for vintage ham radio receivers and transceivers (e.g., Collins, Drake, National, Hallicrafters, Heathkit, etc.). Provides accurate 100 kHz harmonics across HF bands for dial calibration and frequency checking.

"CUR" is the manufacturer code for the crystal maker (common in that era). These were standard, high-stability parts for service and calibration in boat-anchor era equipment.
