Natural Radio, a term coined by Michael Mideke, first Natural Radio editor of The Lowdown; is electromagnetic energy from natural phenomena, occuring at Very Low Frequencies (VLF) and Extremely Low Frequencies (ELF). The frequencies are so low, in fact, that if they were acoustic waves instead of electromagnetic waves, many of these signals would be in the range of human hearing. Therefore, receiving natural radio is basically a matter of connecting a suitable antenna to a high-gain audio amplifier! Some of these phenomena are not too hard to hear, though it helps to be away from power lines. The most interesting natural radio signals are a lot lower level than power line hum in the typical residential area.
