A few old timers like it I guess. It requires too much power and

What? RTTY can be a bit ropey but sitor is good enough for mandatory
installation in the world's shipping. IMO it's a good mode for HF.

For the OP: the DWD also transmits maritime weather information 24/7 in
RTTY on four frequencies from HF to LF.


That's pretty esoteric for this board.

Most of those ancient/archaic modes were "invented" before the computer,
and while tradition is nice, it is folly that, they have not been
replaced with new coding/compaction/encryption routines ... but then, it
is not like the data is a dvd sized sized data chunk ... so a "horse and
buggy" will still work.

As "the traditionalists" age/die/are-replaced, I look forward to this
changing, in the future.
