Introduction: The USA version of Xiegu’s X5105 Transceiver is distributed and backed exclusively by FJ
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
A broadcast band to 54 Hz. 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 eters (amateur bands only) with power output adjustable from 0.5 to 5.0 Watts. Operating modes
include USB/LSB, CW, F , A , plus digital transmissions (1.5-W carrier on A ). 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!

EXTERNAL CONNECTIONS
INTERNAL BATTERY

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 enu-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 FJ 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.
I PORTANT 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.
I PORTANT 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
FJ with a detailed description of the event and request specific handling instructions.

BASIC OPERATION
The X5105 is firmware-driven, so familiarity with the operation of the various controls and with the menu
system is important. To make best use of these instructions, have your radio in hand and walk through each
function as you read along.
[ ] Power ON: Press and hold BOOT (power) button for 1-2 seconds. The radio will beep three ascending
tones* and the Xiegu logo will appear on screen. Then, in 2-3 seconds, the screen will change to the regular
operating display (freq., mode, etc.). Note that the radio’s CSN menu will allow you to personalize your radio
by adding your call and/or name to the power-on boot screen.
[ ] Power OFF: Press and hold BOOT (power) button for 2-3 seconds. The radio will beep three
descending tones and “BYE” will appear on the screen. In 2-3 seconds the screen will go dark, indicating the
radio is fully turned off.
[ ] Forced Reset: In the unlikely event the processor “locks up” or fails to respond to your commands, press
and hold Boot for 10 seconds. This will force a reset of the CU and shut the radio down.
[ ] Band: Step through all US amateur bands by pressing the DN (down) or UP button located on top of the
radio on the righthand side. The menu is circular: 160 > 80 > 60 > 40 > 30 > 20 > 17 > 15 > 12 >
10 > 6 .
[ ] ode: Step through choices using the ODE button to the left of the display screen. This menu is
circular: LSB> USB> CW> CWR(rev)> NBF > A . The X5105 offers a range of special features and
functions for each mode, all covered in detail in the expanded Function enu section of the manual.
[ ] Volume: Change the sound level with buttons marked with a large and small speaker symbol located on
top of the radio, left side. A VOL bar-graph located below the S-meter scale displays the current AF level
from 0% to 100%. Note that the audio signal level routed to the AF-OUT line on the ACC (accessory) jack is
independent of the volume buttons. That level is set in the system menu.
[ ] Transmit Output Power: Press the Po button located above the VFO tuning knob. >TX POWER will
appear on the right side of the display with the output level displayed underneath it (example: 5.0W). To reset,
rotate the VFO encoder knob. Output level will change in 0.5-watt increments from 5.0-W to 0.5-W. Five
seconds following the adjustment, normal VFO tuning will be restored to the encoder.
Important Operating Note: Before transmitting into an antenna with unknown SWR, always reduce power
to the lowest level and engage the ATU (automatic antenna tuner).

Xiegu X5105 QRP Transceiver

[ ] VFO Operation: There are two ways to tune the X5105 VFO:
1. Use the VFO Knob and Step Keys: The current tuning step is highlighted on the frequency display,
and the Step Keys (< >) shifts the highlight left or right. Tuning steps are: 1 Hz > 10 Hz > 100 Hz >
1 kHz > 10 kHz > 100 kHz > 1 Hz > 10 Hz. Use larger steps for out-of-band general coverage
tuning or to change band segments. Use smaller steps to tune in discrete signals. The VFO knob’s
encoder changes frequency by 12 increments with each revolution.
2. You may also use the up (^) or down (v) keypad buttons on the microphone to shift the VFO by one
increment per click. These buttons are located immediately above the Rx/Tx LED.
[ ] ATU (Automatic Antenna Tuner): Press the ATU button once to engage the internal tuner -- the TUNE
icon will appear at the top of the screen. Then, press and hold the ATU button while watching the S-meter
display. When the bar-graph returns to 0 or stops moving, the tuning cycle is complete and the radio
automatically switches back to receive mode. To disengage the tuner, press ATU once and the TUNE icon
will disappear.
IMPORTANT WARNING: Always connect a load to the Antenna connector when testing the ATU or when
transmitting.
[ ] RIT (Receiver Incremental Tuning): This function changes the receiver frequency without changing the
transmit frequency. To enter the function, press RIT. The RIT icon will appear on the right side of the screen,
and the RIT offset in ± kHz will appear directly below it. Rotate the VFO knob to program set the desired
amount of offset. After 5 seconds, normal VFO operation is restored.
[ ] PRE/ATT (Preamp/Attenuator): Press to step through three choices: ATT (attenuator) > OFF (bypass)
> PRE (preamplifier). Note that the preamp is unnecessary on the lower HF-bands and may even cause
front-end overload when many strong signals are present.
[ ] Nose Blanker (NB): Press NB to toggle the noise banker on and off. NB is highly effective for
suppressing impulse noise generated by ignition systems, electric fences, etc. When on, the NB logo
appears next to the FIL (IF bandwidth) indicator. Turn this function off when not needed -- impulse blanker
may make strong adjacent-channel signals appear to splatter or distort. Note that DNR (digital noise
reduction) is more effective for reducing generalized atmospheric static and random electrical noise.
[ ] Data ODE : The X5105 has a built-in receive modem for copying PSK31 (see Function enu
section).
[ ] VFO-A/B: The X5105 features two independent VFOs. These may be set up for two in-band frequencies,
for frequencies on two different bands, and even for split operation using two different modes. Press the A/B
button (above tuning knob) to toggle between VFO-A and VFO-B. The VFO in use will be displayed at the
top-left of the screen as VFO-A or VFO-B.
To operate “split” in DX pileups, set receive frequency with VFO-A and transmit frequency with VFO-B. Then,
turn on the SPL (split) function on menu page-1 ( 1 -> SPL). The radio will now switch automatically from
VFO-A to VFO-B when you transmit. Whenever split is on, the SPLT icon will appear on the screen next to
the AGC icon.
[ ] LOCK Button: The lock feature freezes all controls, protecting them from accidental change. Press
LOCK (small red button to the right of the display) to engage the function. A small Padlock icon will appear
to the left of the button on the display. Press LOCK again to disengage the lock.

Xiegu X5105 QRP Transceiver

[ ] Display Backlight: Press and hold the LOCK button for approximately 3 seconds to toggle the display
backlight on or off.
FUNCTION ENU: any of the X5105’s advanced features are accessed via the Function enu. Use this
section of the manual to “walk through” and become familiar with each one.
FUNCTION ENU PAGES: The Function enu has nine pages ( 1- 9), with three or four entries per page.
The current page number is displayed in a box at the lower-left corner of the display screen. To change the
page, press ENU and the page number will blink. Rotate the VFO encoder to select a new page number,
then press ENU again to lock it in. The menu is circular, stepping 1 to 9.
SOFT KEYS: The four buttons at the bottom of the display screen are called Soft Keys. Each one will be
labeled with a two or three letter designator appearing above it on the screen. Labels for the soft keys
change with each new page.
enu Page-1 [ 1]
[ ] A=B: Press to copy all parameters stored in VFO-A over to VFO-B. Parameters may include band,
frequency, operating mode, etc. After entry, the VFO-A or VFO-B settings may be modified, as needed.
[ ] SPL (Split): Press SPL to initiate automatic split-frequency operation. In this mode, you may tune around
using VFO-A, but when you transmit, the radio automatically switches to the settings you’ve retained in
VFO-B (an important DX operating aid).
[ ] NR (Digital Noise Reduction): This function activates and sets the radio’s digital noise-reduction level.
Press NR and the current NR-Level will appear on the display with a number from 0 and 10. Use the VFO
encoder knob to alter the noise reduction level. When set for 0, the NR circuit is off. When set between 1-10,
it is on. The NR status indicator appears on-screen to the right of the AGC icon.
To adjust, listen to incoming signals and rotate the VFO encoder for the most comfortable processing level.
Five seconds after your last entry, the encoder will revert back to normal VFO operation. Digital Noise
Reduction works well for general QRN, static crashes, splatter, powerline noise, etc. Setting 1 delivers
minimum processing, and 10 the maximum. Set to 0 to turn the function off. Note that NB impulse blanking
may work better for pulsed noises such as auto ignitions and electric fences.
[ ] NTH (Notch Filter): Used to reduce or eliminate unwanted carriers and noise bands. Press NTH to
engage. When set to 0, the filter is off and out of the circuit. When set from 1-100, it is on. Adjust the VFO
encoder to position the notch for minimum interference. Once set, normal VFO operation will be restored
after 5 seconds. The notch filter has no on-screen status icon but should be left off (0 unless needed.

Xiegu X5105 QRP Transceiver

enu Page-2 [ 2]:
[ ] AGC (Automatic Gain Control time constant): The time-constant menu is circular: Slow > Fast >
Automatic > Off. The AGC status icon appears on the display at mid-screen. Icons are AGC-S (slow),
AGC-F (fast), AGC-A (Automatic), and AGC— (Off). The last setting used is remembered when the radio is
turned on. It does not change with the mode unless you have selected AGC-A (automatic).
[ ] FIL (IF Filter Selection): Three IF filter bandwidths are available -- 0.5 kHz default for CW and CWR, 2.4
kHz default for USB/LSB, and 6.0 kHz default for A (NBF uses a different IF signal path). The filter menu
is circular.
Press FIL to deviate from the default setting (FIL changes work in receive mode only). For example, apply
2.4 kHz on CW to listen wide, or 6.0 on SSB for ESSB. You may also narrow the A passband using 2.4 kHz.
However, during transmissions, the radio always reverts to the transmit default. The filter status indicator
appears on the right-hand side of the display (example: FIL-2.4k).
[ ] SR (Scan Receive ode): Press SR and AF output shuts off while the receiver sweeps from below to
above the operating frequency, graphicly displaying band activity. Set Sweep Width by toggling the BW soft
key (wide, medium, narrow). The receiver continues scanning until you press ON to resume listening on
the center frequency, or press QUIT to terminate the scan function and resume normal operation.
[ ] SWR (Plot Antenna SWR). Disengage the ATU before making SWR readings. Connect the antenna or
load under test to the antenna jack and tune the VFO to the desired center frequency. Press SWR to start the
scan. The radio will switch to transmit mode and a graphic SWR display will appear on screen. The default
scan width is 100 kHz in 1-kHz steps ( 50 kHz of center). 1 kHz appears on screen to indicate the step
spacing. The center frequency is also displayed. One complete scan requires about 15 seconds.
Five Scan Width settings are available (from 100 kHz to 500 kHz). Each scan has 100 sampling points, so
the interval between samples automatically increases with the scan width (from 1 kHz to 5 kHz). To widen the
scan, press BW (bandwidth) and toggle through the five choices. With each new choice, the scan resets and
begins over. The radio will continue scanning until you press QUIT. Quit returns the radio to receive mode.
Note that SWR measurements may be limited to in-band frequencies -- the X5105 does not generate
transmit signals outside US ham bands.
Important Warning: When scanning SWR, always confirm that a workable antenna or reasonable load is
connected to the antenna jack.

[ ] >V (Recall emory Channel to the VFO): This function recalls operating channels previously stored in
memory (the X5105 has 100 channels available). To access the memory bank, press >V. A memory
channel icon will flash at the top of the display (CH-00). Scroll the VFO encoder clockwise to select the
channel number you wish to recall (example: CH-03), then press the YES soft-key to complete the transfer.
To escape an operation without completing it, select NO. The radio will return to normal operation. If there
are no saved channels in memory, a emory Empty icon will appear on the soft-key line at the bottom of the
screen.
[ ] W (Write VFO to a emory Channel): To write a current operating setup into memory, press W. The
channel status indicator will flash at the top of the display showing CH-00. Rotate the encoder clockwise until
a number appears with a E in front of it (E indicates the selected channel is empty). To load that channel,

press the YES soft key (or press NO to escape). The radio will store the entry and return to normal VFO
operation. Should you accidentally try to overwrite an occupied memory slot, the operation will abort and
switch the radio back to VFO operation. To write a new setup into a currently occupied memory channel, you
must first clear out the existing data. See C ( emory Clear) below.
[ ] C ( emory Clear): Press C to bring up the Channel Select function on the display (CH-00). Next,
rotate the channel encoder to find the memory slot you wish to clear. Press YES to clear it, or NO to escape.
When completed, normal VFO operation will be restored.
[ ] Read a TAG: The TAG function labels memory channels for more convenient identification. To read an
existing TAG, go to E ORY mode using /V button (upper right-hand corner). Next, use VFO to scroll to
an occupied channel (CH-XX) that has been tagged. To read the TAG, select ENU page 3, then press the
TAG soft key. The soft-key will change to >TAG and the TAG will replace the frequency in the screen display.
Press TAG again to exit back to the operating frequency.
[ ] Write a TAG: Each TAG may be up to 9 characters long. To write a TAG, first select the channel you wish
to label and then go to ENU page 3. Next, press and hold TAG for 2-3 seconds. When you release it, the
radio’s text editor will come up on screen. Locate the blinking cursor in the upper-left corner and rotate the
VFO encoder to find your first character. When it appears, press ADD to lock it in. The cursor then
automatically shifts to the next character. To add a space between words, insert the thin space marker ( _ ).
The space marker is next to the ^ symbol in the character list. To make corrections or deletions, shift the
