This is an acoustic levitation chamber I designed and built in 1987 as a micro-gravity experiment for NASA related subject matter. The 12 inch cubed plexiglas Helmholtz Resonant Cavity has 3 speakers attached to the cube by aluminium acoustic waveguides. By applying a continuous resonant (600Hertz) sound wave, and by adjusting the amplitude and phase relationship amongst the 3 speakers; I was able to control levitation and movement in all 3 (x,y,z) axis of the ambient space. This research was used to show the effects of micro-gravity conditions that exist in the space shuttle environment in orbit, but done here on Earth in a lab. This is not "anti-gravity." So please don't waste time arguing something pointless.

This is a video I took on the 2nd of January 2009 at my amateur radio station. I first heard it on New Year's eve early afternoon. It was on all day today and other ham operators across the country have reported receiving the signal; a very strong signal as well. The frequency of the signal is at 14.250 to 14.255 MHz. It seems to be on at all hours and no one has yet to decipher or explain it. Any theories? Anyone?It is no longer there, and it stopped a few days later. I never heard it again.
