The f3k already has a transverter menu where you can set up various parameters ie freq,power levels etc, so there is no need to add another port.......
Chuck, the f3k can be set up with suitable power levels for the transverter or if you prefer, you can build an attenuator circuit into a small die cast box along with a ptt circuit to switch it in/out. However, this is up to you. If you click on XVTR menu, you will see how easy it is to set it all up
Chuck, the only way then is an external setup as I mentioned with an external relay system +ptt + attenuator. Email me call@yahoo.co.uk and I,ll send you a circuit.
