Interfacing an old MM transverter

[g3yjr]

I have connected the receive line from the transverter to the Transverter In BNC connector on the back of the rig. When I set that transverter to a low power setting the receive works fine, but there is insufficient power to drive the separate transmit line to the transverter.

When I choose H2.5W, I can drive the transmit via the Ant1 socket, but the Transverter In socket seems disabled, so recieve no longer works.

How do I configure the K3 so that I get 2.5W drive out and a separate receive IF line which works?

Connect the receive line to RX ANT IN and press the RX ANT button.

When you use the high power setting on the K3, the most obvious solution
is to change the transverter to a single RX/TX IF connection.
If that is not possible, connect the RX IF line from the transverter to
the RX ANT input and select the RX antenna for that transverter band.

Thanks Joe & Don. I had forgotten about the RX ANT connection. I have a pre-amp conncted to RX ANT in/out, but I think I can daisy-chain the transverter through the pre-amp by-pass connection.  The back of the K3 is getting busy!

Thanks for your help.
