[Elecraft] Sub Receiver I.F. Tap

[Edward R Cole]

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 notice on the sub-receiver schematic dated 8/18/08 that there was a
connector for a plug-in board. I assume it was for an I.F. buffer plug-in
circuit that connects to J93 for an I.F. tap.  I didn?t see that on the
KRX3A but the jumper W3 is near connector J78. Is it possible to attach a
J309 to and duplicate the circuit on the main receiver?
