  Though Part 15 rules may allow the broadcast of a low power signal in
the AM and FM broadcast bands, I'm fairly certain emitting RF to
intentionally interfere with other radio services is ALWAYS illegal. So,
technically, this is illegal. Emitting a powerful signal on 10.7 Mhz is
*especially* illegal.

   Hooking up a spark gap to an antenna does not just radiate audio
frequency energy; it generates fairly broadband RF noise. In fact, some
microwave sources are essentially a spark gap inside a tuned cavity.

  Technically? What you are discussing will generally interfere with much
more than just an audio system. One sure fire approach is to generate a
large amount of RF in close proximity to the system. In general, with
few exceptions, doing this will technically be inconsiderate and
illegal.

  The last time someone asked about this, we ended up in flame war.

  Just try to be an adult.
