INSPIRE is a non-profit scientific, educational corporation whose objective is to bring the excitement of observing natural and manmade radio waves in the audio region to high school students. INSPIRE is an acronym for "Interactive NASA Space Physics Ionosphere Radio Experiments". Since 1990, The INSPIRE Project has been involved in the investigation of very low frequency (VLF) radio signals in the earth's magnetosphere. These signals are both manmade, such as LORAN navigation system transmissions, and naturally occurring, most of which originate from lightning. 

From this web page one will be able to  listen to very low frequency radio signals received by an INSPIRE receiver (located at the University of Florida Radio Observatory). These signals will be amplified and converted to sound.
