is a DSP-based digital demodulation radio based on the SDR (Software Defined Radio) architecture. It features a 192kHz wide spectrum display and waterfall display, along with 16-bit sampling, enabling a high-dynamic receiver with CW, AM, SSB, and FM demodulation capabilities. The receiver is housed in an all-aluminum CNC-finished housing and features a 4.3-inch 800x480 resolution, high-brightness IPS LCD display, all while maintaining a compact design. Take it outdoors now and enjoy the beauty of nature and the joy of listening anytime, anywhere!
