Feature: 1. 【Scientific & Reasonable Layout】: EER Class-E driven SSB transmits stage. IRF series emitter tubes provide high stability. Aluminum housing, aluminum pushbuttons, and translucent silicone pushbuttons can provide longer durability. The QCX circuitry is simplified with 50% fewer mounting elements. Complex transformer windings and wiring are eliminated. Compact size with rich interfaces and scientific layout to ensure superior performance. 2. 【Multi-band Support & High Audio Performance】: Simple, fun, and versatile QRP SSB high-frequency transceiver with built-in DSP and SDR functions. Full mode high-frequency shortwave transceiver, covering eight bands with high transmitting efficiency. Built-in speakers with significantly improved sound quality and increased volumes provide a more pleasing audio experience. The CW tone and sidetones are adjustable. 3. 【Comprehensive Functions & Software Flexibility】: Supports various communication modes, including SSB, CW, DSP, and SDR functions, such as AGC, NR, etc, to provide a professional communication experience. Open-source firmware based on IDE allows experimentation, adds new features, and shares contributions via github. 4. 【Combined Digital & Analogue Technology】: It combines an all-digital SSB emitter with a software-based SDR receiver stage with high sensitivity and selectivity for precise frequency control and signal processing. Its 8-band capability of the 160m-10m frequency scope ensures versatile operation, while the simplified circuitry reduces complexity and installation time. 5. 【Superior Portability】: Powered by the carried external 13.8v powersupply or the built-in Built-in 6000mAh rechargeable lithium battery, this device ensures a reliable and long-lasting powersupply for extended periods of use without frequent recharging. Perfect for various operation scenarios.
