CW does not mean "morse code" as Dan suggested.... CW means "continuous
wave", which is one (slightly misnamed) method of transmitting morse
code... (it's not continuous at all, because it is "interrupted" to
produce the dots and dashes).

Most morse code identifiers that pilots hear are Amplitude or Frequency
modulations on top of a continuous carrier signal, and not "continuous
wave", in the classic sense, at all.
