Barry,
K3 can be set to click.
Just set the rise and/or fall times too short i.e. sharp and listen k#
click.

K3 owners have a big responsibility in setting the radio correctly so it
serves the owner and his neighborhood correctly.
The neighborhood in this case is Fourier transformed into frequency domain
... hey I attempted a nerd joke in English!

Also some other radios, like IC756Pro2 and Pro3 have this feature.
One Finn had changed his CW wave fall time too short - he corrected his
settings after a discussion about what&how to change.

Most people do not know the implications of sharpening the signal.
Over sharpening is not exactly good in this case.
