[Elecraft] K3 + K144XV question

I wrote up how I separated the transmit and receive 2m paths  at:-

I also wrote up how I got a range of output power from the K144XV suitable
for my microwave external Transverters at

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.  

Ideas or suggestions?

I believe the internal xvrtr routes the rcv antenna connection 
through a header on the board and in normal operation, that is 
jumpered. I would think you can remove the jumper and use the header 
to make your receive connection
