There is no antenna tuner inside the KPA500. "Auto-tune" simply means that the amp switches bands automatically by detecting the frequency of RF. A single dit is sufficient. If you have the KPAK3AUX cable connected to a K3, the amp will change bands whenever you change bands on the K3, and conversely, the KPA500's front panel band buttons can be used to change bands on the K3.
The KPA500 is fairly sensitive to SWR. If you use a non-resonant antenna, or if you use a resonant antenna outside its comfort zone (e.g. CW vs phone frequencies on some bands), you will probably want the KAT500. The KAT500 integrates very nicely with the K3 and KPA500, and it works even when the KPA500 is turned off. With this setup, the KAT3 will be in bypass. The only time you will use the KAT3 is when you have an antenna connected directly to the K3, bypassing the KAT500 and KPA500.
