[Elecraft] Diversity reception with two linked K3s?

[Jerry Flanders]

Anybody done this - linked two in a master-slave relationship with 
frequency control via  the serial port or computer program to provide 
diversity reception?

Is there any PC program readily adaptable to this - virtual com port 
splitters, etc...?

I presently use WU2X's PowerSDR and N8LP's LP-Bridge in IF panadaptor 
mode to tune the K3s (each through its own computer), so a method 
adaptable to this setup would be particularly sweet.
