George,
The K3/K3S does *not* inject an audio tone.
It shifts the transmit carrier by an amount equal to your sidetone pitch.
Lower if you are on LSB and higher if you are on USB.
The effect is the same as adding a tone to a perfectly suppressed
carrier, but is guaranteed to be clean.

Another way to look at the use of CW in SSB mode on the K3: What I
think the rig does when you hit the key is inject an audio tone at the
CW offset frequency into the audio chain for the SSB signal. If all
is clean and not distorted, the result will be a single RF frequency
offset from the SSB "carrier", and will be receivable as such by a SSB
receiver tuned to the SSB carrier frequency.
If the K3/K3S doesn't actually generate an audio tone, it sure behaves
like it.
