To use one of their favorite phrases: If I told you that I would have to kill you... ;-)
Seriously, I am afraid I can not reveal my sources, but I can assure you that they are quite reliable.
The technology that they are (supposedly) using on Bald Mtn. is not even classified any more. Its based on the Doppler Effect, which is a slight shift in the frequency of a signal reflected from an object which is moving relative to the observer. If you shoot a laser beam at a car window you can listen to the conversation inside the car by decoding the frequency shifts of the reflected beam, caused by vibrations of the glass. After compensating for the movement of the car with a reference beam, of course. For more info do a Yahoo search on "Laser Microphone". You'll come up with some interesting links.
