The High Frequency Active Auroral Research Program (HAARP) is an ionospheric research program jointly funded by the U.S Air Force, the U.S Navy, the University of Alaska, and the Defense Advanced Research Projects Agency.
Built by BAE Advanced Technologies (BAEAT), its purpose is to analyze the ionosphere and investigate the potential for developing ionospheric enhancement technology for radio communications and surveillance.
Before I knew about HAARP, I looked into the conspiracy side of this. I remember watching a video explaining how it works; by transmitting ELF waves through a group of antennas, it pushes the microscopic molecules in the air upwards.
I decided to build my own transmitter on a very small scale and try it out for myself. Surprisingly, it worked.
