Malcolm and John,

The discussion is interesting from the back of the classroom, and that is 
probably where I
should remain.

The sidetones produced by over coupling are being produced in a test 
situation using
a signal generator. But in a disruptive coil I don't think you will find the 
sidetones because
the energy is not a sine wave. Nor will there be sidetones after the gap has 
fired because
the coupled energy is not coherent like a sine wave.

I'm afraid I have not been too coherent either.

cheers,
