I Wikipedia’d the term “CW” and it means “continuous wave”, to answer my earlier question. This triggers memory on a post a year or more ago in which we exchanged notes about the seeming paradox of using the term “continuous wave” to describe the Morse code technique of triggering the carrier on/off.
It is a bit confusing, but the r-f waveform transmitted during the “on” parts of each Morse code character are comprised of energy having continuous characteristics (frequency, and amplitude) — except for the rise and fall times of transitions between the on and off states.
