The amplitude will of course depend on how strong the audio signal is, but it could develop as much as the CW signal before driving the signal into a non-linear region (that non-linear maximum will depend on the transmitter design - I do not believe that is any need for concern on the K2)
-------------------------------- A few of the 1960's-vintage SSB rig designs used exactly this method of producing CW. It quickly fell from favor because the suppression of the opposite sideband and even the carrier suppression often was not good enough to avoid unnecessary and perhaps illegal levels of spurious signals. Some SSB rigs had no more than 30 dB of opposite sideband suppression, perhaps less. That's about five S-units, so an S-9 signal would have a image signal at about S-4 somewhere between 1 and 2 kHz away (twice the modulating frequency).
