HF QRP SDR Transceiver Optimized from the uSDX QCX-SSB open source hardware, this shortwave QRP SSB/CW transceiver is designed for performance and portability. Its powerful software enables minimal hardware use for SW transceiver functions, supporting SSB, CW, AM, and FM modes. Please note, AM and FM modes are gift functions with limited expectations. Product Features 8 bands: 80m, 60m, 40m, 30m, 20m, 17m, 15m, 10m. Excellent PCB layout for optimal high-frequency performance. Transmits 3-5W power across 8 bands, with upgrade-ready SOT-223 and TO-220 pads. High efficiency: 80-90% for most bands, over 60% for 15m/10m. High-precision KDS TCXO with frequency accuracy better than 1PPM. Ultra-compact size: 83mm x 38mm x 124mm (excluding parts that protrude). Comprehensive interfaces: CAT, PTT OUT, MIC/KEY, K-head microphone. Fully digital and software-based SSB and SDR stages. Efficient and lightweight EER Class-E design. DSP functionalities include AGC, NR, Voice Trigger Xmit, among others. Open-source firmware, compatible with Arduino IDE.
