Phil; How would you switch between the radios? Manual switch? Be sure you also connect that you provide some method for cutting power on the transmitter when the KAT is tuning. This is built into the K3/KPA setup, but you also need to do it for the IC706. You really don’t want to hot-switch the KAT500’s relays at 100 watts+. It would greatly shorten their life.
