I briefly glanced at a page, that to me suggests the complexity of this system.
Will read in depth when I can find the time.
Several ways to find it, name of the page is: "Radio waves below 22 kHZ"
click on the lower right link: "Reception of Submarine comminication systems"
by: R. Romero and V. Lehtoranta. Enlarge the pictures, especially the second- food for thought.
I initialy googled VLF and clicked on the Wikipedia article regarding Very Low Frequencies. One of the links at the bottom is: :"Radio waves below 22 kHz"
I was a 2819 KG 13TtyTech USMC 1973-1977 I was in the rear with the gear.
Carried a rifle and bayonet for 13 weeks in boot camp; damn things get heavy- backcharge them for my lower back.
Cheers
