The Japanese Slot Machine

I've heard about this, but never knew what it sounded like - here's a sample, and it's a rather ugly sound...(from Larry Van Horn)

The only cheap package that I know of that supposedly handles this mode is Sigmira. I' guessing here, but I suspect the big expensive ones like Krypto500 can also do it (although it appears the Hoka packages can't...). You can find the link for that at the UMC page in my sig.

JSM is encrypted. There's no point in attempting to decode it.

Yeah, the Slot Machine, XSL, is an every morning visitor here:

And here it is on 9 frequencies:

As nick said, it is encrypted, so even the packages that do support the mode only give you a raw data output.

T!

There's no guarantee that even if you could decrypt the messages, they would be anything sinister or even useful. Circuits are kept open with dummy traffic so that there is no upsurge in messages if there really is an incident. We had to send fully encoded and encrypted data on a regular basis from ships at sea and get similar replies back from the shore stations - some of the info was useful - we usually got the football results on Saturdays!
