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

I bought a Fucubr Donglr Pro+ AKA FCDP+ or FC+ .
The USB device has a connector to which, via adapter(s), one can connect
any antenna we all own.

So I want whatever antenna the K3 is currently using to let signals from
that antenna, in the Rx mode only, to be present on Rx-Out BNC, on the
back of my K3.

I thought I was perhaps "there" except that the signals appearing on a
waterfall display, of SDR-Radio program, were all but reduced to 0 they
were so very very weak.

Is there another adjustment, in the CONFIG, I need to make?

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.

read the manual. sadly lacking explaining the Rx-Out BNC.

thanks for the help. Basically it's useless in light of the severe
losses. I need it for the three transverters if I want to run MAP65 on
the EME portions. Sig's already weak enough as it is.

hi hi, sorry, I need a new keyboard as this one has rubbed off letter as
well as some keys, I now see, do not type if pressed to lightly.

Bob,

Why don't you connect that Funcube Dongle to the K3 IF OUT jack? That
will provide a broad spectrum at the 8 MHz IF.
