Excellent observation. Learning the full capability of your equipment and how
to communicate under difficult circumstances is the mark of a good operator.
If "arm chair" copy is the only thing one can do, then that operator is not
working at the edge of the envelope.

If the CW signal is not much louder and don't have a lot of
keyclicks, you can usually copy an RTTY signal through an adjacent CW
QRM even when it touches one of the FSK tones.
Unless there are two separate CW QRM signals riding *both* of the FSK
tones, you can copy RTTY that is strong enough by using Mark-Only or
Space-Only copy.
Mark-only and Space-only also works well with two RTTY stations that
are overlapping each other, as long as one of them is not overly
strong as to get their keying sidebands to interfere with the "clear"
tone of the RTTY signal that you are trying to pick up.
