G106 is a 5W portable QRP model with SDR circuit structure which uses 16bit-CODEC sampling and can deliver superior
performance. The whole machine has SSB/CW/AM three modes and extra WFM (88~108MHz) receiving function, allowing you
to listen to local FM broadcasts while communicating. Equipped with a CW digital filter with three bandwidths, it can help you
connect to more and farther radio stations. With the external DE-19 digital adapter (optional), it can be easily connected to the
computer and complete FT8 communication.
As an entry-level portable SDR transceiver, G106 will be a good helper for you to play CW and FT8.
Basic features:
➣High-performance SDR core circuit
➣Compact and robust structure
➣Transmission and receiving of all amateur frequency bands within 3.8~29.7MHz
➣WFM broadcast receiving
➣Shortwave full-range continuous receiving
➣Amateur data communication available
➣Computer online control available
Please read this Manual carefully for a better experience and full understanding on operation of the G106.

Connection of External Power Supply
9-16V external DC power supply can be used for G106. The current load capacity of DC power supply shall be at least 3A.
Attached power lines can be used to connect to radio and DC power supply.
DC power supply shall be connected in strict accordance with following figure to avoid reverse polarity connection.
The white-core line is connected to the positive pole of the power supply, and the metal-shielded line is connected to
the negative pole of the power supply.
White-core line - positive
Metal-shielded line - negative

7
Connection of External Power Supply
EMC ferrite bead can be applied on power lines to prevent external disturbance from entering radio via power lines and
radio-frequency interference in radio from radiating externally via power lines when external power supply is adopted for G106.
Ferrite bead shall be installed at the side closing to power plug to greatest extent.
■ Polarity of power lines shall be carefully inspected to avoid reverse polarity connection when external power supply is
adopted.
■ The limited warranty of the radio does not cover damage caused by an error in external power connection or damage
caused by an abnormal power voltage.
Wind the power line around
the ferrite bead twice.
As close to the interface as possible
