Jim,
The K144XV is natively a single antenna port transceiver.
But if you need separate TX and RX antenna connections for your
transverter, note that there is a jumper setting that can apply +5V on
the output coax during transmit - see page 21 of the K144XV instructions.
You should be able to use that voltage along with a small relay to
change the K144XV antenna between your transverter's 144MHz TX and RX
antenna connections.

Happy New Year to all!
I have a K3 with the internal K144XV 2m module. This works FB but both TX
and RX are on the same antenna port. In a configuration I am thinking of
using, there would be separate RX and TX lines.
With my main 2m EME station which uses a second K3 and a 10m to 2m
transverter, I have it configured with 28 MHz TX out on ANT2 to the
transverter input port and 28 MHz RX in on the RX ANT IN port with the front
panel . This works FB. I have the XVTR PWR menu setting such that it
outputs 3 watts which is directed to ANT2 rather than the XVTR OUT port.
Even though I am using a transverter, I am not using the back panel XVTR IN
and OUT ports.
When I attach the output of a 144 MHz to 28 MHz downconverter RX line to the
RX ANT IN port and enable RX ANT function on the front panel, the K3 with
internal K144 XV 2m module does not give me the desired results.
I hope I have made this clear. It seems that this should work with the
internal module since it works as I want with an external transverter.
