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.

(12) Key wiring diagram

Connect your straight key/paddle Morse key according to the diagram shown in the figure above.
Note:

• If the connector on your straight key is a 6.5mm 2-pole plug, please change it to a 3-pole 3.5mm stereo plug following the wiring shown in the figure above, and connect the live wire of the Morse key to either the “Di” or “Da”  terminal.
  Note:

• Direct use of some2-pole to 3-pole Adapters or incorrect wiring may result in the radio sticking in CW transmit mode.

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 radiofrequency 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.
  

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.

UPDATING THE RADIO’S FIRMWARE:

When an update to the software in the radio is needed to either fix a problem or add a feature a firmware update file will be supplied by your radio dealer, mostly likely over their website. Unless the file is marked as essential or contains  some features that you wish to use, you may choose not to update the radio.
Instructions on the step by step process is documented on both Radioddity and Xiegu’s webpages. The use of the Teraterm program or similar XModem capable software on a PC connected to the radio via the USB interface  (115200,8,N,1) is required and the process is started by holding in the volume knob while turning on the radio. In Teraterm make sure that you enable the 1K block option otherwise the upgrade can fail, leaving the radio inoperative. If  this happens, simply start the upgrade process again.
This manual is based on a radio with the v 1.3 firmware which was installed using this process.
