Three schemes of frequency generators for homemade designs

Highly stable quartz oscillator 5 MHz from the "Hyacinth"

The resonator is excited at a frequency close to the frequency of the series resonance, where the impedance is highly inductive in nature.

Stable LC oscillator 6.5 MHz

Stable LC oscillator up to 100 MHz
