Features:

SDR Technology & Multi-Mode Operation:

This transceiver incorporates state-of-the-art Software Defined Radio (SDR) technology, offering versatile operation modes including USB, LSB, CW, AM, and frequency modulation. It features a DSP filter with selectable bandwidths and DSP functions such as AGC, NR, and ATT, enhancing signal quality and user experience.

Compact & High-Efficiency Design:

Highly portable with its small size and lightweight aluminum housing, this transceiver utilizes an EER E-level driven SSB stage for efficient power consumption. It delivers a maximum 5W PEP SSB output from a 12 V power supply without the need for a bulky heatsink, making it perfect for site operation.

Open-Source Firmware & Customizability:

The device includes open-source firmware built for the IDE, allowing hobbyists and engineers to experiment, add new functions, and share contributions via GitHub. It supports a community-driven development environment that enhances the transceiver's capabilities and ensures continuous improvement. The software-based VOX can be used for quick full invasive (QSK and semi-QSK operation) running in digital mode (without PTT interface) for RX/TX switching, with external PTT output and TX/PA control delay.

Multi-Band Support & Expandability:

The transceiver offers performance loss from 20kHz to 99MHz and supports continuous tuning over the 160m to 10m frequency band. It includes an FT8 option connector and supports optional accessories such as an audio cable and Morse key, providing flexibility for different operating scenarios.

User-Friendly & Cost-Effective:

Designed for simplicity, this transceiver reduces installation elements by 50% compared to the initial QCX circuit, eliminating the need for complex transformer windings and alignment procedures. It includes a built-in mic and speaker, and its straightforward setup and operation make it accessible to both amateur radio enthusiasts and seasoned operators.
