Features:
SDR Technology & MultiMode Operation: This transceiver incorporates stateoftheart Software Defined Radio (SDR) technology, offering versatile operation modes of USB, LSB, CW, AM, and frequency modulation. It
Features a DSP filter with selectable bandwidths and DSP functions such as AGC, NR, VOX, and ATT, enhancing signal quality and user experience.
Compact & HighEfficiency Design: This transceiver is highly portable with its small size and lightweight aluminum housing. It utilizes an EER Elevel driven SSB stage for efficient power consumption, delivering a maximum 5W PEP SSB output from a 12 V powersupply without the need for a bulky heatsink, making it perfect for site operation.
OpenSource Firmware & Customizability: The device comes with opensource firmware built for the IDE, allowing hobbyists and engineers to experiment, add new functions, and share contributions via GitHub. It supports a communitydriven development environment that enhances the transceiver " s capabilities and ensures continuous improvement. The softwarebased VOX can be used as a quick full invasive (QSK and semiQSK operation) or to assist in running in digital mode (without PTT interface) for RXTX switching, external PTT output with TXPA control delay.
MultiBand Support & Expandability: The transceiver provides 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.
UserFriendly & CostEffective: The transceiver is designed for simplicity, reducing installation elements by 50% compared to the initial QCX circuit and eliminating the need for complex transformer windings and alignment procedures. It includes a builtin mic and speaker, and its straightforward setup and operation make it accessible to both amateur radio enthusiasts and seasoned operators.
