The advantage of using FSK is that one can take advantage of the excellent
RTTY filters built into some transceivers. These filters are generally not
available when operating in USB/LSB. This is particularly important to
contesters operating in a crowded environment and DXers dealing with weak
signals.

It also doesn't suffer from the ridiculous printing up garbage because a
shift character was lost. If there ever was an outdated mode, it's RTTY.
Unfortunately logic or technical arguments play very little part in the
reason why people choose to use particular modes. Many RTTY operators insist
on actually FSK-ing their radios instead of using AFSK, even though it means
they have to accurately tune in every signal instead of just clicking on a
waterfall, which would surely be quicker.
