Too bad. It looks like SITOR B and NAVTEX would make a good news

I think it is too hard to encrypt, and it is less reliable than satellite.


FEC-TOR is pretty trivial to encode, it's just the 5 bit teletype code,
with the start and stop bits stripped and some parity bits added, and
the three character block sent twice with some bits inverted.

Remember, this stuff was designed in the late '60s-early '70s to retrofit
onto existing RTTY gear, before the days of microcomputers. Back when
the hardware for a one byte register would cost $20 or so.

But it's all uppercase, so I doubt that any newswire would be interested
anymore.
