I believe ELF is more like 100 Hz, which can be received much deeper, so the
sub can stay at the bottom. 24kHz is VLF.

A first place to look to check out that claim would be:

That may not be sufficient for other uses, such as navigation. Firing
one up for frequency source only would probably not be motivated.

Hi
The *only* way for redundancy to do any good is for it to be designed into
systems. That simply is not done. It was not done back when everything was on
the air. It's not going to be done now (can't) or in the future (prediction).
Why? It costs money, it did cost money, it will cost money.

No you use a great number of tiny
overlapping cells combined with spread spectrum and strong encryption
and you control it with a some kind of self organizing mesh network,
not a top-down control system. What this does is mimic nature.
Think about rats and cockroaches

Good point about WAAS. I wonder if newer timing receivers that support WAAS
would continue to function in a stationary mode if they could only receive
valid signals from WAAS ? I also wonder if the WAAS ground segment would
continue to function without GPS ? That being said the

Perry you mean like the 10' X 10' loop I put up?
It has about 800 ft of wire.
Brang the daytime signal fro 30 uv to an easy 60 +.
