Warnings
1. Please read this manual fully before operation so as to get a good
understanding of the G-106’s capabilities and functions.
2. When using an external mains power supply or battery, carefully
check the polarity of the power cord and do not reverse the polarity.
The warranty of this radio does not cover damage caused by an
incorrect external power connection error or damage caused by
improper power supply voltage.
3. Only qualified technicians shall service this equipment.
4. Do not tamper with the transceiver for any reason.
5. Do not operate the transceiver with a damaged antenna. If part of an
antenna comes into contact with your skin, a minor burn can result.
6. Turn off your transceiver prior to entering any area with explosive or
flammable materials. Do not operate your transceiver in any area near
explosive or flammable materials. Turn off your transceiver before
entering any blasting area.
7. To avoid electromagnetic interference, please turn off your transceiver
in any area where notices instruct you to do so.
8. Turn off your transceiver before boarding an aircraft; any use of a
radio must be in accordance with airline regulations and crew
instructions.
9. Do not place the transceiver over any airbag deployment area in
vehicles containing airbags.
10. Do not expose the transceiver to direct sunlight over a long period of
time, nor place it close to any heat source.
11. When transmitting with the transceiver, hold the microphone 3 to 4
centimetres away from your lips and keep a safe distance away from
the antenna in accordance with the ICNIRP and any additional local
regulations. Copyright

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.

 When on the HF bands, a short-press of these buttons switches between bands
(depending upon what is set in the Band Switch Mode (BSM) this will be just the
Ham bands (Ham) or Shortwave broadcast and Ham bands (Full). A long press (2
sec) on these butting changes the cursor position in the frequency display so
changing the “tuning step” amount when the main tuning knob is turned.
 A short-press of these buttons in the FM mode switches between stored FM radio
stations.
 Pressing both these buttons at the same time locks all buttons and knobs on the
radio.
 Pressing both buttons at the same time again unlocks the radio’s controls.

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 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.
