INTRODUCTION:
The G106 is a basic 5W portable QRP transceiver with an SDR infrastructure
using 16bit CODEC sampling to deliver superior performance. The radio
supports three transmission modes SSB, CW & AM as well as FM (88-108MHz)
on receive only. Local FM broadcasts can be listened to while operating
portable. A digital CW filter with three bandwidths helps when receiving weak
CW signals. With the external DE-19 digital adapter unit (optional) the G106
can be easily connected to a computer to support digital data modes such as
FT-8. As an entry-level portable robust SDR transceiver, the G106 is well
suited to QRP CW and FT-8 operations while also supporting SSB and AM
modes.
Basic features:
 High performance SDR
infrastructure

 Compact and robust
physical
structure
 Coverage of all
HF
amateur
radio
bands
between
3.5 and 29.7MHz
 FM broadcast
receive coverage
 Continuous receive coverage across all HF frequencies
 Amateur data communication
modes are possible by connection to
a computer with the appropriate software installed.

Computer based remote control
is
available via a CAT port.
Please read this Manual carefully for a better experience and full
understanding of the operation of the G106.

Note:
 Direct use of some2-pole to 3-pole

in the radio sticking in CW transmit
mode.

Page 10
CONNECTION OF EXTERNAL POWER SUPPLY
A 9-16V external DC power supply can be used to power the G106. The current load capacity
of the power supply shall be at least 3A. The supplied power lead can be used to connect the
radio and DC power supply.
The DC power supply must be connected in strict accordance with following diagram to avoid
a reverse polarity connection.
The white centre-core wire is connected to the positive pole of the power supply, and the
metal-shield is connected to the negative pole of the power supply.
An EMC ferrite bead has been pre-fitted to the power lead supplied with the G106. Its
purpose is to prevent external noise from entering the radio via its power lead and radio-
frequency interference from radiating externally from the G106 over the power cable. The
other end of the cable is bare wires for the user to fit their own power connector as required.
It is recommended that the user add a fuse in the resulting power lead.


Before connection the polarity of
the
power lead should be carefully inspected
to avoid reverse polarity connection
from the
external PSU


The limited warranty of the radio does not cover damage caused by a fault in
the external power connection or damage caused by an out-of-range voltage
being applied.

OPERATION:
The G106 accesses various functions through the multi-function menus. All
functions are allocated to different menu pages and there are 4 options on each
page.
The menu items can be selected and changed using the following method:
 Short-press any multi-function button to call up the menu and turn the main tuning
knob to switch between the five menu pages in turn.
 Press the multi-function button corresponding to the menu
option
displayed on
the screen to execute the corresponding function.
 Some functions only work if you press "SAVE" after their adjustment. If you press
"QUIT", you will directly exit from the page and the changes will not be saved.

The G106 uses a black and white dot matrix display screen to display all status information in
a user-friendly way. Visibility in sunlight is also better due to the contrast of a black & white
screen.
Alongside the S value is a moving scale that indicates signal strength on receive and power
output on transmit. This is meant to be a user guide only indicating operation.
BASIC OPERATION:
To turn the radio on and off:
1. A short-press on the power button will turn the radio on when it
is in a powered off state.
2. To turn the radio off a longer (about 2 seconds) press of the
power button is required.
To turn off the screen’s backlight during operation:
 A short-press of the power button while the radio is running
will turn off the backlight in the screen.
 A second short press will turn it back on.

Page 13
ADJUSTING THE AUDIO VOLUME / OUTPUT DEVICE:
1. Rotate the volume control knob at the top left-hand corner to adjust output
volume.
2. Short press the volume control knob to switch between the in-built speaker and the
speaker in the hand microphone. A telephone-like symbol will appear at the top of
the display when the speaker-Mic is plugged in and selected. When you quick-press
the volume knob so that the internal speaker is used, the symbol will disappear.
3. If you wish to use your headphones, these can be plugged into the 3.5mm socket
on the bottom of the speaker microphone.
SELECTING OPERATIONAL MODE AND BAND:
1. Press the MODE on the top of the radio to switch to the required mode.
2. Press the BAND left and right buttons to cycle through the bands
1.8MHz*↔3.5MHz↔5MHz↔7MHz↔10MHz↔14MHz↔18MHz↔21MHz↔24MHz↔28MHz
 1.8MHz(160m) is receive only.

Page 14
Setting the Tuning Step (TS) frequency.
To select the step
required when tuning (100Hz, 1 KHz etc) we use the
BAND
buttons as follows:
Long-press the BAND left or right button for 2s to step up or down in the
displayed step value.
Once set, turn the main tuning knob to go to the required frequency.
ENABLING THE RECEIVE PREAMPLIFIER.
To turn on or off the pre-amplifier long-press the MODE button. When
enabled a P will be displayed at the top of the display.
Note: The pre-amplifier is rarely required on the lower HF bands and it is
recommended to turn it off on the higher bands if there are very strong
signals or interference present.

CW MODE OPERATION.
Insert
your
straight
or paddle Morse
key into the KEY interface
on the
rear
of the G106 (see
earlier
for the definition of
connections
).
Suggested configuration
steps
:
1. Turn on the QSK function through the menu settings and set the
required rate by long-pressing the QSK button which brings up the
adjustment. (note: if QSK is not enabled no CW will be transmitted
although in this mode the radio can be used as a CW practice oscillator).
2. Press on the Morse key to start CW communications. (do not press the
PTT on the microphone)
3. In the menu (2/5) select the CWF function to set the filter bandwidth to
the desired value (options are 500Hz, 250Hz and 50Hz) by turning the
main tuning knob. Press SAVE followed by EXIT.
4. Go back into menu (2/5) and this time select the CWT function to set
which sidetone you wish to hear. Again, press SAVE followed by EXIT to
set the value.
You should now be ready to operate on the CW mode however you may also
wish to adjust the following related settings to your taste or as required by
your key. KS: automatic keying rate KM: manual/auto keyer mode. IMB:
IAMBIC keying mode.
LOCKING THE RADIOS CONTROLS
The controls on the radio can be locked or unlocked by pressing and holding
both BAND buttons at the same time for at least 2 seconds. Once locked a
lock symbol is displayed at the top of the display.

The G106 can be connected to a computer and an XPA125B using an optional DE-19 adapter, providing convenience for data communication
and power amplifier control.
1. Connect the units as shown in the diagram above.
2. Install the relevant CH342 port driver for the operating system in use (search online and download).
3. Select the model "XIEGU G106" in the data communication software (or control software) you are using (alt. Xiegu G90 or IC7000)
4. Choose the DE-19 virtual sound ports for sound input/output in your software. Note that different sound devices are required for input
and output.
Note: If you choose a different radio model even one that supports C-IV instructions, some actions will not work.

Page 20
COMPUTER CONTROL INSTRUCTIONS
Once connected via the DE-19 unit or using a USB-to-serial (3.5mm) cable the
G106 accepts CIV instructions at 19200 bps speed (8 bits, no parity). Through
these instructions you can remotely control the transceiver based on
supported instructions (see below) or configure control instructions required
by other software (e.g. digital data modes). Select Xiegu G90 or ICOM IC7000
as the radio in the software if G106 is not shown.
