Main Question or Discussion Point

Does the spark frequency = the interruptor frequency = radio signal frequency.
From the sources I have found these frequencies dont seem to match.
We use a 9V DC one at school.
Many Thanks

Each 'interruption' triggers a diminishing train of RF pulses with base frequency set by the set-up's inherent LC. There will also be a strew of octaves due to the initial 'kick'. Like an old lawnmower, bike etc with un-damped spark ignition, it makes a total mess of local RF environment, so please use due care.
