[Elecraft] What is actually present on Rx-Out BNC of the KXV3 RF bosrd??

[Joe Subich, W4TV]

There is nothing "there" on the RX Out unless one select RX Ant.  Look
at the K3 schematics and read the Owners Manual.  If you want to split
the main receiver antenna feed, you will need to add a splitter to the
RX Out, connect one output port to your "Fucbr" (whatever that is), the
other output port back to the RX Ant jack and select RX Ant.   The
splitting loss will be a killer on 6, 12, 10 and possibly 15 meters so
it will be necessary to use a preamp ahead of the splitter to maintain
sensitivity on those bands.
