I can't speak for details on the K3. Only generally.

It is actually easier to have clean asymmetrical modulation
with low-level AM than it is with a tetrode in a plate
modulated circuit. It is also easier to have better
linearity with low level modulation.

Someday I'll have to get an AM filter and try my K3. I guess
there is no way to use the transmitter without an AM
filter????
