I'm not familiar with CAN-bus. How can I easily implement this in my setup? End
result is I want two way CAT control -- amp gets band/frequency data from the
radio, KPA-1500 remote app gets SWR and power from the amp to display on the PC
and control the power switch and standby/operate from the remote app.

As a homebrew project, if you want "robust" and "just works", it's hard to beat
CAN-bus. A quick Google confirms that for a baud rate of 250K, it will work up
to
820 feet.
