	Radio Electronics had an article a few years ago about how
to detect bugs using a spectrum analyzer. The technique involved
making the house quiet, and then scanning the FM spectrum. You 
then invert and  store this background signal. Next you get someone
to go screaming through the house making lots of noise while
taking a second reading. When you add the two signals you should
see a peak where the the second reading differs from the first.
This is the bug's frequency.
	The technique sounded plausible, but I don't have a spectrum
analyzer so I can't try it out. I would think it would detect the
cheap bugs you find in the hobbyist magazines.
