And you still won't be able to copy anything. Even 10-15 years ago,
about half the FSK out there were these wide shift signals, encrypted
and probably synchronous (no start and stop bits). Speculation: either
broadcasts to maritime (fishing fleets?) or links for military sites
too small for more expensive communications.
