Features
The DUO-ART 120 is an 120 watt amplifier for HF and 50MHz frequency ranges. It includes the internal
PA power supply, preselector filters, an antenna tuner (optional) and acts as remote controller for the
FDM-DUO. The DUO-ART 120 has three modes of operation that are called interfaces:

FDM-DUO. The DUO-ART 120 has three modes of operation that are called interfaces:
-
FDMDUO interface : this interface is used when operating with the FDM-DUO,
-
Generic interface : this interface is used when operating with another transceiver,
-
FT-817 interface : this interface is used when there is the need to read the frequency through
the RS-232 port.

The DUO-ART 120 has 20 memory banks and each one saves :
-
the interface used,
-
the attenuators setting,
-
the antenna used,
-
the use of the antenna tuner,
-
and other settings.
The USA version of the DUO-ART 120 has a security feature that prevents to amplify in the frequency
band 26-28MHz. Any attempt to drive the amplifier in the 26-28MHz frequency band will result in 0dB
gain from input to output of the amplifier.
