Caught this tonight on 8.580MHz. It sounds like the Decepticons from the movie Transformers. But really, what is this???

Saab Grintek MHF-50 modem. Most often used by the South African Navy (maybe the only regular user of this modem?). 8580 kHz is a common frequency for this signal, and is often paired with 12982 kHz USB.
