Hi Andy, The short answer is that neither the KPA500 or KAT500 can source signals - they can only read them from a transceiver and then follow its direction. This means that they can both read the status information from a Kenwood's COM port and act on it.
This does not require the AUX cables which are specifically designed for the K3/K3S to provide the unique features they have when connected in that way. This would include the ability of the KAT500 to read the K3/K3S VFO frequency and pre-select tuning elements, band-tracking with the K3/K3S and the KPA500's ability to report its OPER/STBY status to the K3/K3S so it can switch between the 2 RF PWR settings it maintains on a per-band basis.
