The ending song of an anime television series called Le Eden de la Grisaia here has a light flashing. I suspect it may be Morse Code. By watching the video a little more slowly than usual (frame by frame), it's easy to see that

  • dit is 2 frames
  • dah is 6 frames
  • intra-character gap is 2 frames
  • gap between characters is 6 frames
  • gap between words is 14 frames

So it probably is Morse Code.

I've managed to translate it into letters. Here's my recording of the transmission. - means the light is on. means the light is off.

At the beginning:

--- - --- - --- --- - ---       --- - --- - --- --- - ---       --- --- -   -       -   --- - -   -   --- -

Which is "CQ CQ GE EDEN". Notice there is only 1 dit's time between "C" and "Q".

And at around 1:25:

--- - -       --- - -

Which is "DD".

I haven't used Morse Code before, so I don't know what these letters mean. What do they mean?

EDIT:

Thanks to to a comment by Phil Frost. The TV show is Japanese. I looked up the Japanese equivalent of Morse Code, Wabun Code. If it's in Wabun Code, the transmission would be

リヘ ヘホヘタ

and

ホホ

Unfortunately, I don't know Japanese. So if anyone who sees this happens to know Japanese, please tell me whether the above makes any sense. Googling yielded no results.

CQ is common in amateur radio (not just morse) as a way to initiate communications. It basically means "anyone who can hear this, please respond if you want to talk".

GE could maybe be a typo of DE (-.. .), which is used in morse and text-based communications to mean "this is" or "from" and usually precedes the callsign of the person sending.

Not sure about DD.

"CQ CQ DE EDEN" would make perfect sense, meaning "This is Eden calling anyone." Though I'm not sure why a submarine would flash that on a signal lamp while submerged. "GE EDEN" must be a mistake.

I've no idea what "DD" at the end means. It could be Wabun code. Or it could be someone's initials or similar of significance to the show's creators. Or perhaps an obscure reference to something in the show. Or, another mistake.

Perhaps "GE" means "good evening"!

A long time ago I lived in Japan for 2 years. I still can speak enough Japanese to hold a conversation. This seems to be just gibberish. It actually sound more like something real in English than Japanese, at least to me. Using online translators also yielded no results.

When you call CQ you might send CQ CQ DX DE K9NJS PSE K

Which means that I don't want to talk to local stations. If I wanted to talk to European stations in particular I could call CQ EU, you can use country codes or state abbreviations, etc. You can leave off the DE and you could also just send GA instead of PSE K.

So a possible interpretation could be "EDEN Calling anyone in GE (whatever that is in the context of the anime, never saw it)." In Morse there are prosigns and abbreviations where letters are intentionally sent without spacing when they are known abbreviations that are widely used. CQ could well be one of those, I've certainly heard it sent without the space, although these days many people calling CQ just use an automated senders to send repeated stuss such as CQ messages and they always put in the space. But that is my best guess on this seven year old question.

Oh yeah, it is also customary to indicate you are done with a communication exchange to send e e with a little more space than usual so "dit space dit". I'm wondering if that could be an alternate interpretation of the "D D" in the second morse burst - someone trying to day done, but not with a couple of single flashes. Maybe someone picked the DD who didn't know morse well, but why would they know not to space CQ? Sigh.
