Introduction: The USA version of Xiegu’s X5105 Transceiver is distributed and backed exclusively by MFJ
Enterprises. This unique radio delivers an exceptionally wide range of operating features normally found only
in more-costly base-station radios. For example, the general-coverage receiver tunes continuously from the
AM broadcast band to 54 MHz. VFO tuning is velvet-smooth with a wide range of tuning rates – including
1-Hz steps for critical data reception. DX splits are easy using the VFO A/B function, and a wide-range RIT
with digital readout lets you scout adjacent frequencies in both directions. The X5105 transmits on 160
through 6 Meters (amateur bands only) with power output adjustable from 0.5 to 5.0 Watts. Operating modes
include USB/LSB, CW, FM, AM, plus digital transmissions (1.5-W carrier on AM). There’s also a built-in SWR
Bridge and Automatic Antenna Tuner (ATU) that will put you on the map from virtually any portable location
using improvised antenna systems.

When it comes to pulling weak DX signals out of the noise, the X5105’s “big-radio” features make all the
difference! There’s a built-in Pre-Amp and Attenuator, pulse-type Noise Blanker, Digital Noise Reduction
(DNR), Notch Filter, adjustable AGC-Rate (fast, slow, automatic, off), plus variable high and low pass audio
filters, built in speaker, and plenty of audio power to drive an external speaker. Serious CW operators will
appreciate the built-in multi-mode Automatic Keyer with three memory channels and CW-trainer. There’s
also built-in Speech Processing for added DX punch. The electret hand microphone features a multi-function
key-pad that places many of the radio’s advanced operating features right at your fingertips. Whether
operating indoors or out, the X5105’s large 3.6-inch high-visibility back-lit screen displays every aspect of
your radio’s operation with easy-to-read numerals, letters, and analog scales. And, even though the X5105 is
physically small, all operating controls are clearly marked and spaced apart to accommodate adult-sized
fingers!

Thanks to all these features, you can say goodbye to the tangled patch cables and add-on boxes that
normally accompanies QRP operation. There’s even a front-panel microphone and manual transmit switch
for operating “handy-talkie” mode. Best of all, the powerful 3800-mAh on-board battery pack delivers 6 to 8
hours of energy-independent portable operation between charges. The radio operates from any external
9-15 Volt 3-Amp dc supply, and a built-in smart-charger monitors battery condition. Even though it’s loaded
with special features, the X5105 measures just 6-5/8” wide x 3-5/8” high x 1-7/8” deep and weighs just 2.1
pounds with the battery included. Positive proof that remarkable things come in small packages!

INTERNAL BATTERY

4

Xiegu X5105 QRP Transceiver

The X5105 comes with a built-in 3800-mAh battery pack. When no external power source is connected to the
power jack, the battery supplies power to the radio. When a power source is connected, the radio senses the
external voltage and switches over to it.

Charging Procedure: You may listen to the X5105 while it is charge mode -- but avoid transmitting while
charging is taking place. The combined current required to simultaneously transmit and charge the Lithium
ion cells could exceed the capacity of the radio’s power-management components. To initiate a charge cycle
while the radio is operating:

Scroll to Menu-7, select [CHG] (charge), then select CHG ON (charger on).

To ensure a full charge, apply at least 13.5 volts from the external power source (normal charge range is

13.5–14.0 volts). Charging begins automatically and is monitored by the charge controller.

The maximum charge time required for a fully depleted battery is 12 to 15 hours. When the battery is fully
charged, the charge controller automatically terminates the charge cycle.

When your radio is turned off with external power connected, the battery automatically recharges, as needed,
to restore a full charge.

When battery power is nearly depleted, the battery symbol located at the upper right corner of the display
screen will appear to be “empty” . At this point, you should switch to an external supply or recharge the
battery right away. Note that during the recharge cycle, it is normal for the X5105 heatsink and case to
become slightly warm. Normal life span for the internal battery is about three years. Contact MFJ Enterprises
to order a replacement when you observe a significant drop in capacity or if the battery fails to hold a charge.
Note that routine battery replacement is not covered under warrantee.

IMPORTANT OPERATING WARNING: DO NOT abruptly disconnect the power supply when the X5105 is
connected to an external power source and the radio is transmitting. Doing so can damage the radio’s
power-management components. Also, avoid transmitting while simultaneously charging the battery.

IMPORTANT BATTERY WARNING: Lithium-ion batteries are widely used in electronic devices and the
technology is safe. However, in rare isolated cases, Lithium ion batteries have been known to fail internally
and overheat. Should such a failure occur involving the battery in your X5105, the radio’s enclosure would
likely become extremely hot to the touch. In this event, disconnect the radio’s external power source and
immediately remove the radio to a well-ventilated flame-resistant area. After the case cools down, contact
MFJ with a detailed description of the event and request specific handling instructions.
