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. 73, ...

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?
