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.
