He took those secrets to his grave. I could never get it out of him what he did that was classified. Although I did find several books and research papers in his basement about sonar and radio communications…
Anyways, great article that gave me a bit more insight into what my Grandpa might have been up to.
is discovery ever intentional :)

I found a slightly clearer diagram of the Cutler array:

I love that they de-ice the antenna array by plugging it into the grid and sending 3 megawatts into the wires

RF Science is fascinating. Now might be a good time to ask; Does anybody have any recommendations on scientific books/papers/articles on the effects of RF spectrum (all frequencies) on Human Biology and Physiology? There is a lot of nonsense/hysteria out there but i would like to know the actual experimental evidence and science.
This highlights a huge problem that ELF faced: Most people don't understand this stuff at all, and cannot tell the difference. On the other hand, the researchers and Navy were always very reluctant to go into the specifics of the technology, for military secrecy concerns. Beyond the sensible secret keeping, this always results in a much larger vague area where people don't want to talk even though nothing serious would be leaked because the laws are strict and figuring out the exact limits of what's classified is itself fraught.
So if on the other side you got people who are chaining together all the even vaguely EMF-related news and discoveries, and associating it all with a huge military secret project that no-one wants to talk about, and on the other side you got a bunch of people who actually know what's going on but are unwilling to give straight answers to even relatively simple questions because they are scared of accidentally divulging some key details that are classified, lots of people drew the frankly reasonable conclusion that there is something rotten here.
To put it simply, the kind of massive transmitters used by ELF and VLF projects would not be useful for working in the bands where the Frey effect works. The most efficient antennas are half- or quarter-wavelength, which for the Frey effect would be somewhere around 10-20cm (4-8 inches).
Both of those of course use a way too high frequency signal for it to be meaningfully received by the Frey effect.
