LOL 😂 You’re putting words in my mouth. I said no such thing, in fact I’ve been saying the opposite. Put on your listening ears. The sub is not (rpt not) capable of transmitting at ELF frequency. Even if it had a transmitter, which it doesn’t. It would require a *very large* antenna at ELF frequency. And a lot (rpt lot) of transmit power. Not only that but the land-based system is not (rpt not) equipped with a RECEIVER. It only has a TRANSMITTER. Hel-loo! Earth to audiozenology! Come in! 👨🚀The way the ELF system actually works is much more logical than you’re wild imagination. The submerged sub RECEIVES the ELF message, Then it nearly surfaces to have two-way communications on VLF frequency. 3-30 kHz. But even the sub’s VLF antenna is very long. Hel-loo! Do the math!
So, to have only one-way communication on ELF frequency of 76 Hz a huge antenna and enormous transmit power plus a super-sensitive receiver on the sub is required. 84 miles and 1 Million watts. That’s just for one-way communication. Follow?
See, that wasn’t so difficult, was it? Of course this is all moot since the ELF system was dismantled so time ago in 2004.
Wiki quick study,
ELF radio waves are generated by
lightning and natural disturbances in Earth’s
magnetic field, so they are a subject of research by atmospheric scientists. Because of the difficulty of building
antennas that can radiate such long waves, ELF frequencies have been used in only a very few man-made communication systems. ELF waves can penetrate
seawater, which makes them useful in
communication with submarines, and a few nations have built military ELF transmitters to transmit signals to their submerged submarines, consisting of huge grounded wire antennas (
ground dipoles) 15 - 60 km long driven by transmitters producing
megawatts of power. The US, Russia, India, and China are the only nations known to have constructed these ELF communication facilities.
