On: Japanese Slot Machine (XSL)

I don't know, this is not my area of expertise. But at least from what I've read about other number stations, not all of them are intelligible (e.g. UVB-76 [1])

I should clarify that by “intelligible” I meant that a human can make out the symbols being said (words or numbers) and write them down for later decryption, not that their meaning is readily obvious to people without special knowledge. It sounds like UVB-76's broadcasts (when it's not just buzzing) would be “intelligible” in the sense I was thinking. The Japanese Slot Machine seems like something only machines could work with.

I could tell the connection speed of a modem by listening to the handshake. Does that count? Serious/not serious.
