We found this circuit in the October 1970 issue of Radio Electronics magazine. It uses the then-new CA3018 integrated circuit from RCA. Some resistors are required for best performance.
This circuit was found in a 1977 radio amateur manual. Integrated circuits are operational...
In the figure we show a configuration for a crystal-controlled overtone oscillator using a...
The transistor used is a high current Darlington, but an equivalent discrete configuration can be...
