User Manual
The
open-source project for the enclosure, which you can 3D-print yourself,
is available below:  Exactly the same device, now in a much easier-to-assemble and lower-cost version!  The bottom PCB is fully populated with SMT components, making assembly easier and faster while reducing costs. To distinguish if from the other board, the bottom PCB is designed as KT-033.  The components that require assembly are shown above: the microcontroller, LEDs, displays, buttons and GPS receiver. All of these components are easy to assemble. KT-019

 KT-005 review on
SOTA Reflector: KT-005
Review
 July
2025: The first confirmed SOTA expedition to use the
KT-005 was by EA4R (Alfonso).
When it comes to hiking, size matters. The KT-005 ATU was digned to meet the need for quick antenna tuning in all field conditions. Special thanks to Alfonso, EA4R, for sharing the photos.  24.08.2025:
Another great example of building a super-portable
radio station using
the ATU (KT-005) with the QMX transceiver. Such a compact setup is a perfect solution for SOTA operations. Thanks to David, CT7AUP, for sharing the photo.  June

Questions
& Answers:
Q: Why was the ATU KT-005 project created?
A: There were no antenna
tuners on the market appropriately sized
to match the portable QCX® and QMX® transceivers. The KT-005 is half the size of previously available solutions, offering true portability without compromise. We built the ATU we'd want to carry with us on every SOTA summit. Q: Is
the visual resemblance to the QCX®/QMX® transceivers
coincidental?
A: No — the
ATU KT-005 was deliberately designed as both a visual and
functional extension of the QCX®/QMX® transceiver series. Aesthetics matter. More products in this series are on the way (e.g. the KT-019 NanoSpeaker — see the datasheet in the section below). Q:
Why were SMA connectors used instead of BNC connectors?
A: Our
top priority was maximum miniaturization. Even the smallest right-angle
BNC connector would have noticeably increased the device's size. In the current design, there's literally no space left inside. You can see this for yourself in the project documentation. To connect the ATU directly to the transceiver, we recommend using a compact BNC-to-SMA adapter. SMA connectors also offer lower signal loss. Q:
Why did the development of the ATU
KT-005 take
so long?
A: Well...
the ATU project turned out to be much more complex than
it initially seemed. Our goal has always been to resolve all known issues and deliver a product with factory-level quality — not something that still feels like a prototype. We hope this approach is both understood and appreciated. --------------------------------------
