I then could hear some actual sferics, but they were quite distant I'm sure - the weather in the southeast is now very calm so I figured it was from some thunderstorms in the Midwest. I moved the radio to the other side of parking lot at the top of Little Mountain and things settled down nicely. The North American Coal Corporation’s Red Hills Mine is just a few miles away, in Ackerman, MS. First I heard a slight bit of power-line hum and lots of noisy interference, which I attributed to some large machinery a few miles away. Initially the earbuds literally buzzed in my hand after I turned on the receiver I'm glad I did not have them in my ears, but I had read about this and knew to be careful.Īfter adequately grounding the radio (or was it just hand capacitance?) the earbuds stopped chattering in my hand and I carefully put them in my ears. Yesterday afternoon I drove out to a place called Little Mountain on the Natchez Trace Parkway at Jeff Busby Campground in Mississippi, turned off my car, plugged in some iPhone earbuds and then the W3R. Steve has for the first time in history, captured and recorded "the sounds of the Aurora Borealis and the EMF discharges of lightning bolts bouncing and stretching through the earth's magnetosphere." For an example listen here.Īs Steve notes, "Everyone has seen or has at least heard of the hauntingly beautiful Aurora Borealis or Northern Lights but only a select and elite few have experienced their spectacular, compelling and beautiful sound". Using this and similar models, Stephen produced five natural VLF radio MP3 Albums, including, "Electric Enigma" and "Aurora Chorus".

The WR-3 converts 0.2-11 kHz radio frequencies directly to audio signals, which can be monitored and recorded directly from a portable hand-held unit powered with a 9-volt battery. The WR-3 is a hand-held VLF receiver designed for especially for listening to naturally-occurring extremely low frequency (ELF) and very low frequency (VLF) radio phenomena, like lightning storm atmospherics. Recently I received a radio built by Stephen McGreevy, N6NKS.
