So do I. I had him build me an 8x4 version. Six RX antennas feed the 
matrix, plus the output of an NCC-1. Two of the outputs feed the NCC-1, 
the out of the NCC-1 feeds input #7, RX out of my primary K3 feeds input 
#8.

The other two outputs feed RX In and Sub RX in of both K3s. This setup 
provides lots of flexibility -- I can phase anything with anything. 
During 6M season, a GAs-FET preamp gets patched between RX out and the 
matrix. It's slightly better than what's in the K3.
