Wayne,
Wouldn't you hear it on a radio in CW mode? The tone is added in receiver,
so hearing tone means hearing "pure carrier". Last I knew CW is the "pure
carrier".

Ed,
You should not hear a hum or buzz when listening to the XG3 on a
receiver. The fact that's it's not a sinewave doesn't mean that it has
audio-frequency modulation; it is a pure carrier. You might be hearing
60-Hz pickup due to the lack of a common ground, etc.
