VLF event data, recordings, and live streaming is possible, all from a PVC pipe active E‐Field antenna receiver, GPS timing receiver, and a Raspberry Pi. Using a simple E‐Field VLF receiver, a GPS timing receiver, a Raspberry Pi with Audioinjector soundcard, it is possible to build a fully contained low power VLF reception system to detect natural radio events in the VLF/ULF band using open source software that will capture, GPS timestamp, and filter (remove mains hum) the VLF audio feed and record, detect individual events, detect sudden ionospheric disturbances, and perform analysis on detected events. These propagation conditions allow for other natural radio events like tweeks, whistlers, and chorus to propagate well within the Earth‐ionosphere waveguide. The VLF and LF bands have their own unique useful characteristics and these will be discussed further on. It has been designated a VLF-LF receiver, because it tunes the VLF-LF range from 10 to 300 kHz, but it also tunes part of the MF spectrum from 300 to 500 kHz. Because most of a lightning discharge's spectral power is within the Very Low Frequency (VLF) and Ultra Low Frequency (ULF) bands, the emissions from lightning discharges (sferics) propagate rather easily across the globe. The superheterodyne receiver described is the result. It's possible to detect half of the world's lightning anywhere on Earth.
