"Communications using Morse code by keyed continuous waves" in contrast to 
"communications using Morse code by keyed damped waves," which was the type of 
signal emitted by those old spark and arc transmitters of yesteryear, until 
alternators and vacuum tube oscillators were available to emit continuous waves 
during key-down.  CW vs. DW!

I wish that there were allowances for damped wave transmissions by amateurs 
somewhere above 1500 meters for one night each year.  Dust off that crystal set.
