RTTY can still be heard on the amateur radio bands at various baud
rates and shifts based upon the current band conditions.  It is quite
possible to copy 110 baud RTTY by ear and an old friend of mine could
do so.  It's dying out though because the modern digital modes have
much better performance under marginal conditions.
