Certion types of welders use a high frequency generator, have a spark gap, 
and do a pretty good job of mucking up reception. Specifically TIG 
machines set up for aluminum. (The older and more out of adjustment the 
better for this application)

If someone complains a welder is a bit more easily explained than a tesla 
coil. Plus I'm quite certion some kind of signal could be arranged so the 
welder in the basement always strikes his arc at the proper moment:)
