XIEGU G1M HF Four Band Portable SDR Transceiver User Manual

HF Four Band Portable SDR Transceiver
G1M
Operation Manual

The new generation G1M (SDR version) is a 5W portable QRP model with an SDR structure. Its core is based on 16bit-CODEC sampling and has excellent performance. The newly added AM broadcast reception capability allows you to listen to news broadcasts from around the world; the 800Hz narrowband CW digital filter makes transmission easier and clearer.
As an entry-level SDR portable, G1M (SDR version) will provide you with as many new technology experiences as possible.

• Basic Features:
• High-performance SDR core circuit design
• New spectrum display function
• Added AM broadcast receiving mode
• Added CW Trainer function (supports full insertion)
• Adaptive speech noise reduction HF continuous reception
• Support for amateur data communication
• Support computer online control

9. COMM interface
   PC Communication interface/firmware upgrade interface

10. KEY interface
    This interface is a 3.5mm stereo jack (3-pin) for connecting manual or automatic telegraph keys.

11. SPK External speaker interface
    This interface is a 3.5mm stereo jack (3 cord) for connecting external passive speakers. The interface definition is as follows.

12. DC IN external DC power interface
    This interface is a 5.5*2.5mm DC power socket.

13. Grounding screw nut
    Ground connection for equipment.

Note: The MIC pin has a bias voltage and cannot be shorted.

The G1M can use a 13.8V external DC power supply. The DC power supply has a current load capacity of at least 3A. The supplied power cord can be used to connect radio and DC power.
When connecting the DC power supply, please carefully connect according to the following figure to avoid the polarity of the power supply being reversed.
The white core wire is connected to the positive pole of the power supply, and the metal shielded wire is connected to the negative pole of the power supply.

When the G1M uses an external power supply, in order to prevent external interference from entering the radio through the power line, and radio frequency interference in the radio radiates outward through the power line, an EMC magnetic ring can be placed on the power line. Install the magnetic ring as close as possible to the side of the power plug.

When using an external power supply, carefully check the polarity of the power cord to prevent the polarity from being reversed.
The limited warranty of this radio does not include damage caused by an external power connection error or damage caused by an abnormal power supply voltage.
The G1M uses the multi-function menu mode for various functions to be used or turned off. All functions are distributed in different menu pages, and each menu has 5 function options. The operation is as follows: Light press the main knob to switch the four-page menu in turn.
The five multi-function buttons at the bottom of the screen correspond to the displayed function menu.
Light press the “lock” button to switch the menu page. Hold press the “lock” button to lock the button operation

The G1M uses an OLED display screen that displays all status information for the convenience of the user. The visual effect in outdoor sunlight is also very good. NOTE Transmission status operating mode: Working frequency display areaWork status display area /Spectrum/menu area

Connection to a computer

The G1M can be connected to a computer and controlled with the associated software.
Connection cable method:

1. Install the driver for the data cable on the PC side
2. Plug the data cable into the COMM port and connect the G1M to the computer.
3. Run the corresponding computer software.

When using software such as HRD, G1M must be in VFO mode cannot be in channel mode, otherwise, it will not be able to connect.
Computer control instruction
G1M uses the standard CIV instruction set. You can use the standard instructions of this instruction set to remotely control the transceiver. You can also configure the control instructions of other software to control the G1M.
Band voltage data
G1M’s ACC port provides band data for four bands. The band data can control the peripheral device to automatically switch the band or share the band information with other devices.

In the other frequency bands except for the above four amateur bands, the band voltage is uniformly outputted at a high level, 5V.
