The ATU-1k2 antenna tuner module is a passive module, which
means that there are no control electronics on the ATU-1k2. On
the ATU-1k2 coils and capacitors are switched via a connector
strip. It is intended that the ATU-1k2 is used together with
the DP-AMP controller. For this reason, the ATU-1k2 was
developed without its own control electronics.
