You need something called a Front End Saver.

Another alternative to a second receiver is using PowerSDR software with
LP-PAN, but this requires additional hardware (KXV3, LP-PAN, decent sound
card and a decent computer).  You use PowerSDR as your second RX.

"LP-PAN allows you to use your PC / sound card as a second receiver with
lots of nice features if you use the PowerSDRTM app. Shown above is split
operation using the main and sub receivers in PowerSDR. VFO A (green) from
the K3 is linked to the main receiver in PowerSDR, and VFO B (blue) is
linked to the sub receiver. The K3 doesn't need the KRX3 2nd receiver
option. PowerSDR provides both receivers. PowerSDRTM has lots of flexibility
in terms of modes, bandwidths, interference reduction tools, etc. I find
listening to SW broadcasts with the synchronous AM detector very nice."
