Upgrade your QRP Labs QMX+ with an integrated internal battery system and amplified speaker audio!

The QMX+ Internal Battery & Audio Board Builder Kit is based on the open-source QMX+ Battery & Audio Board project designed by TA7MNA (Mustafa Necati Annakkaya). The board mounts directly above the QMX+ main PCB and provides a compact way to add internal battery power, charging circuitry, battery management, and amplified speaker audio inside your QMX+.

CQ Homestead Supply packages the project as a convenient builder kit, eliminating the need to individually source the various supporting boards and installation components.

This is a builder kit and requires assembly, soldering, modification of your QMX+, and final testing by the end user.

Choose the Correct Version

Two separate versions are available:

12V QMX+ Builder Kit Version 2
For QMX+ radios originally constructed for 12V operation.

9V QMX+ Builder Kit Version 2
For QMX+ radios originally constructed for 9V operation.

IMPORTANT: You must purchase the version that matches the voltage configuration of your QMX+. The 12V battery board must NOT be installed in a QMX+ configured for 9V operation. Applying the 12V battery system to a 9V-configured QMX+ can damage the radio.

What This Modification Adds

Once assembled and properly installed, the Battery & Audio Board provides:

• Internal rechargeable battery capability

• Integrated battery management

• USB Type-C battery charging

• Internal amplified audio

• Internal speaker capability

• Direct mounting to the QMX+ main PCB

• A compact installation designed specifically around the QMX+ platform

The result is a much more self-contained QMX+ that is especially convenient for portable operation, POTA, field use, emergency communications, and grab-and-go QRP operation.

CQ Homestead Supply Builder Kit Include the following:

Our 0% kit is intended for builders who want to complete this modification themselves without having to track down the various small boards and installation components individually.

The kit includes the Battery & Audio main PCB along with the additional supporting boards/modules and installation hardware/components supplied by CQ Homestead Supply for completion of the modification.

Our 95% kit has the add on board completely assembled. End user completes the soldering and instalation into the QMX+ Radio.

All kits include a small speaker, that is installed by the end user.

To aid in locating the USB C port that needs to be cut in the rear pannel, CQHS provide a self alinging plastic template that locates the opening for easy drilling and filing by the end user. A 3mm or 1/8” drill is needed and not supplied. To finish the opening, small files are needed such as the Harbor Freight 4614 file set. Youtube How To Video: https://youtu.be/pv2CbtIN7ZQ

18650 lithium-ion batteries are NOT included.

Builder Skill Level

Intermediate

This is not a plug-and-play accessory.

Installation requires the builder to work inside the QMX+, assemble the Battery & Audio Board, solder components and modules, install headers and connections, and perform final inspection and testing.

Builders should be comfortable with:

• Through-hole soldering

• Basic electronic assembly

• Working with PCB headers and small modules

• Reading assembly instructions and PCB markings

• Checking polarity and connections with a multimeter

• Working safely with lithium-ion batteries

• Modifying and working inside an assembled QMX+

• Minor metal working skills

Careful assembly and inspection are particularly important because incorrect battery polarity, incorrect wiring, or selecting the wrong voltage version can damage the QMX+.

Battery Information

The internal battery system uses three 18650 lithium-ion non-protected cells.

Batteries are not included with this kit.

The builder is responsible for obtaining appropriate matching 18650 cells and installing them with the correct polarity. Only quality cells from a reputable supplier should be used.

Charging & Operation

The modification provides a dedicated USB Type-C connection for charging the internal battery pack.

The QMX+'s existing USB Type-C connector remains the radio's data connection and is not used to charge the internal battery pack.

Follow the project documentation carefully regarding charging, external DC power, battery installation, and power-down procedures. Always power off the QMX+ before connecting or disconnecting the DC power supply. Inserting or removing the DC jack while the battery board is installed can trigger a voltage transient as power switches over, which risks damaging the mainboard's voltage regulators.

Important Builder Notice

This product is supplied specifically as an amateur-radio builder kit.

CQ Homestead Supply does not install this modification into your radio as part of this product listing. Final assembly, installation, inspection, testing, and safe operation are the responsibility of the builder.

Always completely power down the QMX+ before connecting or disconnecting external DC power as directed by the project documentation.

Before applying power, double-check:

• QMX+ voltage configuration

• Battery polarity

• BMS connections

• Charger connections

• PCB orientation

• Header alignment

• Solder joints

• Speaker/audio connections

Never install the 12V version into a QMX+ configured for 9V operation.

Open-Source Design Credit

The QMX+ Battery & Audio Board was designed by and with permission of TA7MNA / Mustafa Necati Annakkaya and released as an open-source project for the amateur-radio community.

CQ Homestead Supply is providing a convenient builder-kit package based on this project. The original designer's identification and board markings are retained—we do not rebrand the project as our own design.

Project documentation, design information, assembly information, and updates are available from the original QMX+ Battery & Audio Board GitHub repository.

Please review the original project documentation before beginning assembly.

Please Note

QMX+ transceiver and 18650 batteries shown or referenced are not included.

This listing is for the Battery & Audio Board Builder Kit only.

Please verify whether your QMX+ is configured for 9V or 12V operation before ordering.

Basic Instructions from Necati, TA7MNA Github page:

Audio Calibration

• Set radio volume to minimum.

• Adjust the LM386 board's variable resistor until audio is barely audible.

• Use radio's volume knob for future control.

Drilling a Hole in the Backplate

This step can be a bit tricky. First, you need to mount the board on top of the mainboard and secure it using 11 mm nylon hex spacers. Then, mark the backplate accordingly for drilling. Screwing the board in place ensures proper alignment and helps prevent mistakes.

On the first radio where I installed my board, I made the mistake of not aligning it properly — the charging port ended up slightly higher than the hole. Fortunately, it still works.

Adding a Speaker

For the speaker, you can use either a 0.5W or 1W 8-ohm speaker. Small laptop speakers matching those values should work as well. Attached the speaker on top of the BMS using double-sided foam tape. When the enclosure is screwed down, the top cover presses against the speaker, holding it securely in place.

Notes on RFI

Since there is an RFI source inside the enclosure, some noise may occur in the 9V models. However, the 12V versions are free from battery board-induced noise, except during charging. Please keep this in mind when using it with 9V models.

In our tests with the 9V regulator, we observed that it caused QRM at certain frequencies. However, this noise was often at a lower level than QMX’s own birdies and was not disturbing. When we connected an antenna to the QMX and listened, the noise remained below the noise level coming from the antenna.

The precision milled top cover provides a clean and professional appearance while maintaining durability for portable and field radio use.

Designed specifically for:

• QRP Labs QMX+

• AC8L ATU

Important Notice: OLED Power Readings & Low-Power Tuning

CQ Homestead Supply incorporates modifications to the AC8L ATU's RF sensing circuit to improve tuning performance at low power levels, particularly when using the QRP Labs QMX and QMX+ radios. These changes have not been included in the Github documents, but are from the developers of the ATU design.

The original 10:1 RF sensing transformer has been changed to 5:1, and the resistor-divider circuit has been modified to increase sensitivity. These changes improve tuning reliability when operating at reduced power, including during the QMX/QMX+ Tune SWR function.

OLED Power Reading:

Because of these modifications, the optional OLED can display approximately 16 times the actual RF output power when EEPROM Cell 31 is set to 10. For example, an actual output of 1 watt may display as 16 watts, while 6 watts may display as 96 watts. Users should devide all readings by 16 to get an approximate reading if cell 31 is set to 10. Changing Cell 31 to 05 adjusts the firmware's RF transformer setting and reduces the OLED's displayed power reading. All CQHS kits are programed with cell 31 set to 5 to give the user the closest posable reading.

Important: The setting of Cell 31 to 05 may prevent the tuner from initiating a tune below approximately 1 watt on standard configured QMX+ radios. Operators using higher-power QMX/QMX+ configurations may find this acceptable.

These incorrect readings are normal and do not indicate a problem with the tuner. SWR and tuning information remain useful, but the displayed power should not be considered an accurate wattmeter reading. It should only be used for general reference only and verified by a dedicated watt meter for precise measurements.

These modifications prioritize low-power tuning over displayed power accuracy.

We recommend using the QMX+ reduced-power Tune SWR function when performing antenna tuning if you are using the BS170 power mod.

Smooth Magnetic Paddle Action

One of the standout features of the VK-6 is its magnetic centering mechanism.

Instead of relying solely on conventional mechanical spring pressure to return the paddles to center, the magnetic mechanism provides a smooth and consistent return action.

The result is a responsive paddle that can be adjusted to match your preferred operating style while minimizing friction in the mechanism.

Independently Adjustable Paddles

Every CW operator develops a slightly different preference for paddle feel.

The VK-6 allows you to independently adjust both paddle spacing and tension, giving you control over how far each paddle moves and how much force is required to activate it.

Whether you prefer an extremely light touch for higher-speed CW or slightly more resistance for deliberate sending, the VK-6 can be adjusted to suit your operating style.

Adjustment tools are included.

Polished Carbon-Fiber Paddles

The VK-6 features polished carbon-fiber finger paddles with smooth, rounded edges.

The lightweight paddle material complements the low-friction mechanism and magnetic centering system, providing a comfortable contact surface for extended operating sessions.

It's a particularly useful feature for contesting, extended CW activations, and operators who spend significant time behind the key.

CNC-Machined Construction

The VK-6 isn't a lightweight plastic portable paddle.

Its body is manufactured from CNC-machined aluminum alloy with a durable sandblasted finish, while silver-plated copper contacts provide the electrical switching surfaces.

At approximately 18.9 ounces, the VK-6 has enough mass to provide a stable operating platform on a desk, portable table, or field operating surface.

The combination of aluminum, copper, carbon fiber, and precision-machined components gives the VK-6 the substantial feel expected from a premium CW paddle.

Iambic CW Operation

The VK-6 is a dual-paddle key intended for use with an electronic keyer.

One paddle generates dits while the other generates dahs. When both paddles are squeezed together, a compatible electronic keyer can automatically alternate dits and dahs using Iambic A or Iambic B operation.

This allows for faster, more efficient Morse code sending than a traditional manual straight key while maintaining consistent element timing.

Most modern HF transceivers already contain an electronic CW keyer, so no separate external keyer is normally required when using the VK-6 with a compatible radio.

VK-6 vs. VK-5 — Which CW Key Is Right for You?

The Xiegu VK-5 is a traditional straight key. You manually control the length and timing of every dit and dah. It's an excellent choice for operators who enjoy traditional CW, are developing their manual sending rhythm, or participate in events such as Straight Key Night.

The Xiegu VK-6 is a dual-paddle key designed to work with your radio's electronic keyer. The keyer generates correctly timed dits and dahs based on your paddle inputs, allowing faster and less fatiguing CW operation.

Choose the VK-5 if you want the classic straight-key experience.

Choose the VK-6 if you want the speed, precision, comfort, and efficiency of a modern iambic paddle.

Excellent for Portable CW

Although the VK-6 has the solid construction and weight expected from a shack-quality paddle, it's still compact enough to take into the field.

It's a great choice for:

• Parks on the Air (POTA)

• Summits on the Air (SOTA)

• Field Day

• CW contesting

• QRP operation

• Camping

• Portable amateur radio

• Emergency communications

• Home HF stations

Its substantial base can also be an advantage in the field, where ultra-light paddles sometimes have a tendency to move around during operation.

Compatible Xiegu Radios

The VK-6 is designed for use with several popular Xiegu transceivers, including:

• Xiegu G90

• Xiegu X6200

• Xiegu X6100

• Xiegu G106

• Xiegu X5105

The VK-6 may also work with other amateur radio transceivers equipped with a compatible 3.5mm TRS paddle input and electronic CW keyer.

Classic Straight-Key CW Operation

The VK-5 is a true manual CW key.

Unlike an iambic paddle where the radio's electronic keyer generates properly timed dits and dahs, a straight key puts the operator directly in control.

You control the duration and spacing of every dit and dah.

For operators learning CW, this provides an excellent way to develop timing, rhythm, and a recognizable CW "fist."

For experienced operators, it provides the traditional tactile operating experience that has been part of amateur radio since the earliest days of the hobby.

It's also a great choice for events such as Straight Key Night or anytime you simply want to get back to traditional CW operation.

Adjustable to Your Operating Style

CW operators can be particular about how a key feels — and for good reason.

The VK-5 allows adjustment of both the contact gap and spring tension, letting you tailor the operating force and travel to your preference.

Adjust it for a lighter, quicker touch or increase the resistance for a more deliberate traditional feel.

The key also provides a crisp return action to help maintain smooth and consistent manual keying.

Built to Stay Put

A portable CW key that's constantly sliding across the table can quickly become frustrating.

The VK-5 uses an elongated aluminum base, substantial 13.4 oz. weight, and anti-slip rubber pads to provide a stable operating platform.

At approximately 7 inches long, the VK-5 remains compact enough to transport while providing enough mass and surface area for comfortable operation.

This makes it useful as both a portable field key and permanent shack straight key.

CNC-Machined Aluminum Construction

The VK-5 isn't built around a lightweight plastic base.

Its housing is constructed from CNC-machined aluminum alloy with a durable sandblasted finish.

Internally, silver-plated copper contacts provide the electrical switching surface.

The combination provides a solid feel along with good durability and corrosion resistance for operators who expect to regularly transport their equipment into the field.

Plug-and-Play 3.5mm Connection

The VK-5 uses a standard 3.5mm TRS plug and includes the necessary PVC connection cable.

Simply connect the key to the appropriate CW/key jack on your compatible transceiver, configure the radio for straight-key operation when necessary, and you're ready to send CW.

Compatible Xiegu Radios

The VK-5 is compatible with several popular Xiegu HF transceivers, including:

• Xiegu G90

• Xiegu X6200

• Xiegu X6100

• Xiegu X5105

Built for POTA & Field Operation

The HF-009 was designed with portable operation in mind.

Unlike mobile-style HF antennas that require a magnetic mount or vehicle body to provide a ground plane, the HF-009 includes its own ground spike and three radial wires.

That means you can establish a complete vertical antenna system directly on the ground at a park, campsite, field location, or emergency operating site.

Drive the spike into suitable soil, connect and spread the three radials around the antenna base, assemble the vertical sections, and you're ready to begin tuning.

Quick Slide-and-Lock Tuning

Changing bands doesn't require swapping coils or disassembling the antenna.

The HF-009 uses a slide-and-lock manual tuning system that allows you to adjust the loading coil for the desired operating frequency. Fine tuning can then be performed using the telescopic whip.

Once you've recorded the settings for your favorite frequencies, repeat setups in the field can be completed much faster.

For the best results, we recommend using your radio's SWR meter, built-in SWR scanner, or a NanoVNA / antenna analyzer when initially establishing your preferred tuning positions.

Up to 12.1 Feet Tall

When fully deployed, the HF-009 can reach approximately 12.1 feet / 3.7 meters in height.

Rugged Outdoor Construction

The HF-009 uses high-grade aluminum alloy and stainless-steel components with an anti-corrosion coating for field use.

The adjustable loading coil is housed inside the antenna assembly rather than being left exposed. This helps protect the coil and adjustment mechanism during transportation and outdoor operation.

The result is a portable antenna designed to handle the repeated setup, teardown, transportation, and outdoor conditions that come with regular field operation.

Excellent Match for the Xiegu G90 and the QMX+

The HF-009 makes an excellent antenna companion for the Xiegu G90 20W HF SDR Transceiver.

The G90's built-in SWR scanner and automatic antenna tuner make it particularly convenient for use with an adjustable portable antenna like the HF-009.

Mechanically adjust the HF-009 as close to resonance as practical, verify the SWR, and then allow the G90's internal ATU to handle the final match when necessary.

The combination creates a compact portable HF station with:

• Up to 20 watts RF output

• Built-in antenna tuner

• Built-in SWR scanner

• Multi-band HF capability

One Antenna — Multiple Ways to Deploy

One of the biggest advantages of the HF-010 is its ability to adapt to different operating locations.

Soft Ground

Operating from a park, campsite, field, or other location with suitable soil?

Use the supplied ground spike to install the antenna directly into the ground and deploy the included radial system.

Concrete & Hard Surfaces

No place to drive a ground spike?

The HF-010 includes a portable tripod, allowing you to establish the antenna on concrete, pavement, rocky terrain, patios, or other hard surfaces.

A supplied weighted water bag can be used with the tripod to improve stability without requiring you to carry a heavy permanent weight into the field.

Fill it when you arrive and empty it before packing up.

Stationary Vehicle Operation

The HF-010 can also be adapted for use with a compatible magnetic antenna base and the appropriate optional HF-010A accessory.

This provides another useful configuration for operators working from a parked vehicle or temporary mobile station.

The antenna should not be operated from a vehicle while the vehicle is moving.

80 Through 6 Meter Coverage

The HF-010 provides broad HF and 6-meter coverage in one portable antenna system.

Supported amateur bands include:

• 80 Meters

• 60 Meters

• 40 Meters

• 30 Meters

• 20 Meters

• 17 Meters

• 15 Meters

• 12 Meters

• 10 Meters

• 6 Meters

This makes the HF-010 a strong choice for operators who want to carry one antenna system instead of multiple single-band antennas into the field.

Dedicated 80-Meter Loading Coils

Getting a compact portable vertical to operate on 80 meters requires substantial electrical loading.

The HF-010 addresses this with dedicated fixed loading coils for 80-meter operation, while the adjustable sliding coil provides tuning for other HF bands.

This gives operators access to the lower HF bands without carrying a separate 80-meter antenna system.

Quick Sliding-Coil Tuning

For operation from 60 through 17 meters, the HF-010 uses a smooth sliding tuning coil that allows you to quickly adjust the antenna for the desired frequency.

Fine tuning can then be accomplished using the telescopic whip.

Radioddity even includes a tape measure so you can record your preferred antenna settings.

Once you've established the correct measurements for your favorite frequencies, write them down and use those measurements during future activations. This can significantly reduce setup time compared with starting from scratch every time you change bands.

Always verify your final SWR before transmitting.

Built for Repeated Field Use

Portable antennas get assembled, disassembled, packed, transported, and exposed to outdoor conditions far more frequently than a permanent station antenna.

The HF-010 addresses this with upgraded 304 stainless-steel threaded connectors at critical connection points.

The sliding loading coil is also enclosed, helping protect the tuning mechanism against dust, moisture, and physical damage during normal field use.

These improvements make the HF-010 particularly attractive for operators who expect to use their antenna regularly rather than only occasionally.

Complete Portable Antenna Kit

The HF-010 is designed as a complete portable antenna system rather than simply an antenna element.

Included with the system are the components needed for multiple types of field deployment, including:

• HF-010 vertical antenna components

• Telescopic whip

• Adjustable loading coil

• Dedicated 80-meter loading components

• Ground spike

• Portable tripod

• Weighted stability water bag

• Three ground radial wires

• 32.8 ft. / 10m 50Ω coaxial cable

• BNC-to-SO-239 adapter

• Cable-management spools

• Tape measure for recording tuning positions

• Padded Oxford carrying case

Everything packs neatly into the supplied carrying case for transportation and storage.

Excellent Match for the Xiegu G90

The HF-010 makes an excellent premium portable antenna companion for the Xiegu G90 20W HF SDR Transceiver.

The G90's built-in SWR scanner and wide-range automatic antenna tuner complement the manually adjustable HF-010 particularly well.

Adjust the HF-010 as close to resonance as possible, check your SWR, and then use the G90's internal ATU when necessary to complete the match.

Together, the G90 and HF-010 provide a highly capable portable HF station with:

• 80–6 meter coverage

• Up to 20 watts RF output from the G90

• Built-in G90 automatic antenna tuner

• Built-in SWR scanning

• Multi-band adjustable vertical antenna

• Ground spike deployment

• Tripod deployment

• Three-radial ground system

• 10-meter coax feedline

• Compact transport and storage

Add a suitable battery and logging equipment and you have the foundation for a serious POTA, SOTA, camping, or emergency communications station.
