How does spark gap transmitter work?
a spark gap as an “oscillator.” Being connected directly to the antenna, the broad spectrum current fluctuations at the spark gap are radiated by the antenna. Note that with the gap firing, its 2 Ω resistance completes an RF path from the antenna back to ground, allowing current to flow in the antenna. How Spark Transmitters Work
What should the spark pllug gap be set at?
The spark plug gap adjustment should not be changed more than 3 times and should not exceed .008" in either direction. Excessive changing of the spark plug gap setting will result in weakening of the spark plug ground electrode and can lead to breakage. Also, the spark plug gap should never exceed .055" unless pre-set by the manufacturer.
