W2NAF-KC3EEY VLF Observatory - A Year of Operation

After a year of operation, the W2NAF-KC3EEY VLF Observatory has detected thousands of sferics and tweeks, over fourty whistler events, two major dawn chorus events, two SAQ transmissions, and the first ever Amateur VLF transmissions from Radio Ameteur DL3JMM at 8270.03Hz using the EbNaut digital mode. This demonstrates that a simple VLF receiver with powerful signal processing from vlfrx-tools software using a Raspberry Pi, soundcard, and GPS receiver can serve both the VLF professional and amateur community. Using this, it's possible to construct a network of VLF receivers and perform signal processing from multiple locations for applications such as lightning location and location of other natural radio signals, sferic analysis, natural radio event study in multiple locations, interferometry of Amateur VLF transmissions, and more.
