WRONG! CW is a carrier amplitude-modulated by a series of square waves,
and the harmonics of which that square wave consists excite IMD in the
gain stages! The IMD from those harmonics is what we hear as clicks. The
faster the rise time, the greater the order and magnitude of the
harmonics produced, so the louder and wider are the clicks. An important
reason the K3 is MUCH cleaner than nearly all other rigs is that they
have carefully shaped the keying waveform to minimize the amplitude and
order of those harmonics. AND - they refuse to give us menu settings to
screw it up, a mistake that virtually every other manufacturer makes.
