Jerry,
Its tempting to think maybe the sub-Rx could be used duplex with
main-Tx in the K3, but as you discovered its not possible as DSP is
in use for Tx or Rx, but not both simultaneously.
There is a kind of solution, though, if you own both K3 and KX3:
Set K3-2M to listen on 145-MHz and use K3 with 432 transverter to
transmit 435 (or vice versa). The "big" issue is linking frequency
control of both radios for tracking Doppler changes. This will take
sw via ports in each radio.
This will be a third-party sw source an not "likely" accomplished
thru firmware updates. Amsat has had what they call the "One true
way of tracking"; have to research that to find out if it still exists.
I know a ham that might develop such sw but have not contacted him, as yet.
