Who do I believe more, a denier of everything or a guy who has been into ham radio since 1938 and who has been an engineer? I'll go with the latter. I have listened to the links you see.

It is worth noting most underwater cold war Radio systems used ELF transmission technology's.

From the land to the sub, but never the other way, and at about 72Hz for the Navy version. Not 25MHz.

ROTFL. yeah, dismiss Phage & common sense why don't y'all. He's right, and a simple google search can back him up easily there. The high frequency bands do not propagate through water well. This so-called base signal sounds like several things to me, like RTTY (as someone already mentioned) and I do hear a distorted meteofax-like signal if I listen closely. Probably satellite signals mixed in, too, I think those start around 8 mhz & go up in frequency to around 8k or 9k mhz.
I don't have a handlheld HAM, I just listen online. However, I do try to make sure I understand what I'm hearing, and all this sounds like is the normal high band stuff jumbled together, nothing unusual.

I'm an engineer. And I've had way more than a ham license, although I had a general when I was in high school. And a 1st class RT license.
Listening to the links should tell you this is some sort of modem. Which would be excruciatingly common on that band.
