SPARK_GAP_OSCILLATOR
A high-voltage current-limiting transformer (T1) supplies power to the basic LC tuned circuit. As C1 charges to near the transformer's maximum output voltage, the spark gap's air space breaks down, completing the circuit between the inductor and capacitor, L1 and C1. The tremendous inductive kick in the circuit is caused by the inductive field collapse when the spark gap shorts out the LC series circuit. The LC tuned circuit oscillates in a very broadband manner.
