I like to tell people that I always keep my promises, but not always on time. To wit, after an epic search, I’ve located a cheap and effective source of VLF receivers (out of Italy, which seems to be a hotbed of VLF research as it relates to earthquake prediction, among other applications).
Phase One (proof of concept) of the Deming Box Experiment is imminent. Using my VLF receiver, I will first measure the VLF energy and frequencies in my Hum location and ensure that I can in fact sense the Hum. Then I will enter a steel storage container and, surrounded by steel sheeting, will repeat those measures. If I can show that my setup effectively and demonstrably blocks VLF signals, and if the Hum is silenced, this would be a significant finding, and then I will move full speed to conduct the double-blind controlled study.
As always, I’ll let you know what I find.
