Looking at KX3 diagram, the signal goes trough low-pass filters and band-pass filters. Both are separate for 30-20 and 17-15 bands. So soem but probably not much attenuation from 20 to 15 and vice versa. The attenuation between 17 and 40 is likely much stronger. I assume that the front end in KX2 is same as in KX3.
The bandpass filters in K3 also cover two bands but have extra caps switched in, probably for single band coverage. This would explain why K3's are not interfering much cross band.
