Hi Bill,
A sort-of recent firmware change removed the ability to link vfo by a half-long

is a new config menu item VFO LNK that you use to link the vfos (set to YES).
Also, in diversity, VFO B is not set equal to VFO A

You probably need to set the K3 to output the right selection to the KRC2.
Check the K3 manual for the KRC2 menu entry - in the rev D10 manual it was on

Essentially, select the KRC2 entry in the K3 configuration menu, then tap the 1
