The semaphore had been transmitting the audio broadcast of Neil Armstrong's historic moon landing in 1969. That's right, not the text but the actual audio...

He discovered a pattern that led him to believe it could represent a space — or a silence — in an audio file, and when he graphed the results it looked like an audio wave. He dismissed that as being too difficult but came back to it and eventually ran his results into a program that would convert his numbers to audio. The first results came back sounding like chipmunks squeaking.

So he tweaked things and found himself listening to the historic broadcast, which ends with Armstrong's famous line, "That's one small step for man, one giant leap for mankind."
