[Elecraft] using the KX2 as a remote control head for K3

[Matt NQ6N]

I seem to recall this being discussed with the KX3, but I haven't been able
to find the relevant discussion.

I'm curious if the KX2 can be used to control the K3 remotely in the same
way that a K3 can be used to do so.  Any tips or links to help me figure
this out would be much appreciated.

I am using RCForb connected to the K3 in the shack, but also have an RRC
remote unit and would consider any other options.
