I brought out the 1st IF of the sub receiver from that point using 
0.001 uF disc ceramic coupling cap to RG-174 coax snaked out thru a 
hole in the sub-Rx shield to a BNC on  back panel of the K3.

I think that connecting the coax via a capacitor would load and mistune the
I.F..  That's why the main receiver was designed with a buffer JFET.
