You will need a (hybrid) splitter ... connect the common port of
the splitter to the RX ANT Out jack, connect one output of the
splitter to RX ANT IN and connect the other output of the splitter
to the SDRPlay antenna jack.
A splitter is necessary to keep one receiver from loading the
other resulting in loss of sensitivity. The receivers (K3, SDRPlay)
do not have identical input impedance across their range and one
receiver or the other can become (relatively) deaf on certain
frequencies depending on the characteristics of the input circuits.
There are those who will say use a BNC T ... that may or may not
be satisfactory depending on cable lengths and receiver input
characteristics. Unlike a hybrid splitter, the BNC T connector has
no isolation between output ports which allows spurious signals
generated in one receiver to be coupled directly into the other.

Hello gang,
Is there a proper port on the K3S to connect a SDRPlay that would
allow for sharing the main antenna while receiving, then be
disconnected and isolated when the K3S go into transmit?
Thanks
