I can hear no clicks at all into my sidetone when using my G4ZPY straight
key !



Listen on another RX, not sidetone.


Yes. In many (perhaps most) rigs the side tone has very little relation to the actual transmitted CW signal. It is only an audio oscillator (or tone generation routine in a microprocessor) that gets keyed nearly simultaneously with the real TX output. In many cases it will follow high speed keying input very accurately even when the real RF output dits and dahs are chopped short.
