Joe, The KX3, KX2, and K3/K3S should have virtually the same keying bandwidth. They all use the same raised-cosine keying envelope shape, and this is by far the dominant factor unless the transmit final amplifier is being overdriven.
We looked at this in independent reviews and our in-house plots. The keying BW looks pretty much the same on all three rigs. The 100 W K3 may be a tiny bit better, but there's nowhere near "twice" the difference. The K3S (or K3 with KSYN3A upgrade) does have the edge in composite, wide-band transmit phase noise. RMDR for the K3S (or K3+KSYNA) is roughly the same.
