Ships on the high seas occasionally currently make some use of shortwave radio, but its importance has greatly diminished in the last few decades. The Coast Guard still maintains a "watch" on emergency shortwave frequencies, listening for distress calls, but most transoceanic ships are now equipped with more modern, higher-bandwidth satellite communications systems.

There’s no equivalent SWL library I know of to record the sounds of various shortwave tech as it passes away never to be heard from again, e.g. Loran A signals on 1.85/1.95 MHz. Same for ships at sea.

@[email protected] There are some archives out there, but they're scattered and largely poorly indexed.

I meant, library equivalent to the Internet Archive. Well, I imagine the NSA has one, but…

Thanks!

ps, I ran across the Radio South Africa sign-off on YouTube a while back. It seemed very exotic to me as a kid listening on my radio in Washington State.

@kyhwana @mattblaze

Thanks! LORAN A sounded a lot different. It operated around 1.8 MHz. It was more of a droning, like a piston engine airpland cruising along. LORAN C operates at 100 kHz and sounds more impulse or digital to me. I was actively listening in the late 1960s and LORAN A went away in favor of LORAN C in the early 70s. Soundtrack of my youth, along with WWV😂

@wa7iut @kyhwana That's also my recollection of what LORAN-A sounded like. More of a buzz than a pulse (which is how LORAN-C sounds).

The Russian Woodpecker (which was actually Ukrainian!) is another of the sounds I won't forget but that are almost lost to history.
