Strange morse code choir on shortwave, could it be a sign?

  • Was scanning the shortwave bands on SSB with my trusty Grundig G3 when I came across a really weird signal of what could possibly be multiple morse code signals.

    Taken together, they sound like an creepy eery choir. It almost sounds musical.

    I’d love to know what this was. Utility signals?

    Or could it be the message alerting us to the apocalypse?

    One can only wonder…
