Doesn't matter if the SDR Play input is well above 50 Ohms. What
matters is the *RELATIVE DIFFERENCE* between the SDR and the K3.
Unless both track closely the lower impedance device will "suck out"
signal from the higher impedance device.
In addition, one still needs isolation to prevent

You can also get away with a cheap 75 ohm Cable TV splitter, but they use
F-connectors.
Of course to get anything out of RX ANT OUT you have to press the RX ANT
My measurements indicate the SDR Play input Z is well above 50 ohms and no
degration in signal strength was noted.

Might try IF Out port on the KXv3b Panel. (Page 4, tag 35 of manual).

HiMiniCircuits makes them. There usually are a few on ebay. 73 Tom

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
Yes, you will need a Y cable, connect to RX ANT IN and OUT. The junction
of the Y goes to the SDR Play. To activate, press the RX ANT on the
radio. This sends the ANT 1 or ANT 2 signal to the Out and then back to
the In via the Y cable, while feeding same to the SDR play.
Works great. I use
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
