DP-AMP Sixty One ATU Module

The new antenna tuner module is a passive module, which means that there are no control electronics on the ATU module. Coils and capacitors on the ATU module are switched via a connector strip. The ATU is intended to be used together with the DP-AMP controller. For this reason, the ATU was developed without its own control electronics. In contrast to the ATU-1k2, the wired capacitors have also been replaced by SMD components. The ATU is used up to 30 MHz, it should be possible to use adapted antennas in the VHF range without any problems. Above 30 MHz, the tuner is switched to bypass by the software of the DP-AMP controller.
