1 Introduction
1.1 Notice
Amateur radio regulations vary from country to country. Check your local amateur radio regulations and
requirements before operating the ELAD DUO-ART.
1.2 Precautions
• Connect the amplifier only to a power source described in this manual.
• Take care when plugging-in cables, avoid applying sideways pressure that might damage the
connectors.
• Avoid operating in wet conditions.
• Ground all outdoor antennas for this amplifier using approved methods. Grounding helps
protect against voltage surges caused by lightning. It also reduces the chance of build-up of
static charge.
1.3 Software and firmware versions
The features described in this manual refers to the following versions :
User Interface software
Internal firmware
Version 0.42 - date 04/12/2018
Version 0.58 – date 04/16/2018
1.4 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:
- 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.

3 User Interface
3.1 Main View
When the DUO-ART 120 is started the main view is displayed. The main view is divided in five horizontal
sections. The top one shows a graph with the current transmission power and transmission frequency.
The second section is a status bar that includes information about the current settings. The third section
is a diagnostic bar that shows some diagnostic information. The fourth section is used to show warnings.
The last section is the menu bar which is composed of six choice corresponding to the six push-buttons.
The first one and the last one have an long-press option to open other views.
The configurations are saved in memory banks, and it’s possible to switch between them pressing the
“MEM” button. The banks can be added or deleted until a maximum of 20 banks. The two underlined
button (MEM and VIEW) have a second function if pressed longer.
The “IN-ATT” button allows to choose the Stand-by mode and to set the input attenuators value (0, 2, 3
and 5 dB).
The “ANT” button allows to choose the antenna connector used to transmit.
The “TUNE” button allows to enter in the tune menu.
The “SET” button allows to enter in the settings menu.
The “VIEW” button allows to change the displayed graphic :
- View 1 : forward power and reflected power,
- View 2 : forward power and SWR,
- View 3 : forward power and input power,
- View 4 and 5 : spectrum view.

When the Main View is displayed, doing a long-press on the “MEM” button opens the Memory Bank
View that contains all the presets which can be personalized. There are different parameters and also
the possibility to change the interface used, the interfaces permit to the amplifier to work in different
ways in order to be use also if not used with the FDM-DUO.
Using the “UP” and “DOWN” button it is possible to go through the table and modify it.
3.3 Information View
When the Main View is displayed, doing a long-press on the “VIEW” button opens the Information View
which displays some information about the DUO-ART 120 amplifier.
