The Xiegu G90 is a portable 20W HF amateur radio transceiver with 24-bit 48 kHz SDR architecture and a built-in
automatic antenna tuner. The display panel and the main unit can be separated to enable remote mounting of the
display panel. It delivers excellent performance on both transmit and receive and is highly configurable. Standout
features include the following:
High performance front end with pre-selectable filter options;
Frequency range of 0.5-30MHz, SSB/CW/AM/ FM*1 operating modes;
30 x 35 mm high brightness full colour TFT LCD screen;
±24 kHz bandwidth spectrum display with waterfall function;
Software defined narrowband filter (CW mode: 50 Hz);
Detachable display panel;
Up to 20W RF output power;
Built-in wide range ATU;
Diversified interfaces, In particular, the baseband I/Q output allows it to interface with any external device that can handle baseband I/Q,
including sound card-based or PC-based applications such as XDT1.
In order to derive the maximum utility from your new transceiver, please read this manual carefully before use.
*1: The FM mode can only be turned on when the forthcoming GSOC controller/panadapter is used.

The G90 will operate best with a 13.8V external DC power supply with a continuous current load capacity of at least 10A. The supplied power cable
must be used to connect the radio to the DC power source.
Please note the polarity of the wiring before connecting your radio to a power source. Reversing the polarity can cause damage to the transceiver
that will not be covered under warranty.
The red wire is connected to the positive terminal of the power supply, and the black wire is connected to the negative terminal.
When using an external power supply, a ferrite ring can be fitted to the power supply cable to help minimize external interference from entering the
radio, or to prevent RF from the radio being radiated via the power cable. The ferrite ring should be installed as close as possible to the radio’s power
socket.

Wrap power cable twice
around the ferrite ring, as close
as possible to the radio power
socket.

Powering the transceiver on and off
To turn on, press and hold button.
To turn off, press and hold button for one second or more.
To turn off the display, press the
button briefly. To reactivate the display,
press again, or press any other button
or rotate any control knob.

Available frequencies may differ depending on the regulations applicable to the specific country or region in which the G90 is
sold.
The G90 covers the 10 HF Amateur bands
located between 0.5 and 30 MHz. Band- and
mode switching can be performed using the
buttons on top of the display unit or those on
the multifunction microphone.

Operating mode selection
Different operating modes can be set for VFO-A and VFO-B.
NOTE: The FM mode can only be activated when the GSOC controller/panadapter is connected.
Press either [MODE]button to cycle through the operating
modes as follows:
：
Mode down

Volume Control
VOX mode
Press the [FUNC] button, then briefly press the volume knob inwards to access the VOX menu settings as follows:
VOX OFF/ON: To activate/deactivate the Vox function.
VOX GAIN: Vox Gain adjustment.
ANTI-VOX: For suppressing audio feedback between the microphone and internal speaker.
VOX DLY: Vox turn-off delay setting
The Vox function can be enabled for both the hand microphone and the line input socket. This can be useful when running digital modes
using RX and TX audio cables, as TX keying can be done automatically with the need for CAT control.
When using the AF IN port of the ACC interface for line input voice control, set the appropriate input volume level in the system menu.
This also affects the VOX level setting.
Rotate the volume knob left or right to adjust the AF
output volume.
Briefly press the volume knob inwards to select
headphone mode.

Multifunction knob (MFK)
The operation of the multifunction knob can be customized according to your own preference.
Use of the MFK：
By default, turning the MFK will change the
selected frequency in 100 kHz steps.
To allocate a different function, press and hold the MFK for two
seconds, then rotate the main tuning knob to select one of the
options that appear on the display screen:
1) Change frequency in 100 kHz steps;
2) Squelch level;
3) Transmit power level;
4) CW key speed;
5) FFT Scale –adjusts the sensitivity of the waterfall display.
Once the desired function has been selected, press the CMP button to save or the AGC button to exit. Rotating the MFK will now adjust
the selected function.
To adjust the squelch level, briefly press the MFK, and then turn the main control knob to select the desired squelch level.
Press the MFK again to confirm.

Setting RF TX Power
When using the G90 transceiver for the first time with a new antenna, we recommend setting the RF transmit power to
the lowest possible level to avoid damaging the transceiver due to an antenna mismatch.
Briefly press the [Po] button. The power level
will be displayed on the right hand side of the
screen. Rotate the main control knob to vary RF
TX power output in steps of 1 Watt. Press the
knob in to confirm the setting.

Setting the operating frequency (tuning)
Inputting a frequency directly using the microphone keypad:
Press the [F-INP ENT] button on the microphone. On the G90 display, the cursor will flash awaiting input;
Enter the frequency value you want to select, including point separator, and press the [F-INP ENT] button again to confirm.
For example, to set the current frequency to 14.09000MHz, key in as follows:
1. First press the [F-INP ENT] button;
2. Press the 1 4 . 0 9 0 0 0 number keys in sequence;
3. Press the [F-INP ENT] button again to confirm.
This can be done using the main control knob, the MFK
or the microphone keypad.
When using the MFK, the frequency will change
in steps of 100 kHz (this is the default stepping).
When using the main control knob, the
frequency stepping can be changed by
successive presses of the knob. The cursor on
the frequency display will move accordingly.
