HTOOL SDR-V5 Portable Full-Band SDR Receiver — 100kHz–149MHz, 4.3-inch IPS, 16-bit ADC

Compact, portable software-defined radio covering 100kHz–149MHz with a minimum frequency step of 1Hz. Supports CW, AM, SSB, WFM, FM stereo and aviation bands to satisfy both professional monitoring and amateur communication requirements. Digital signal processing is combined with Tayloe quadrature mixing technology and a Si5351 clock generator to deliver ultra-low-noise Zero-IF (ZIF) reception. Real-time spectrum and waterfall visualization render a 192kHz bandwidth while 16-bit ADC sampling provides high dynamic range and precise signal resolution. Designed to meet civilian radio equipment access standards; maximum input power is limited to -20dBm for safe operation. Frequency stability is maintained by a TCXO 26MHz±0.5ppm high-stability crystal. Housed in a full aluminum alloy CNC body (140×74×22mm) weighing 388g, the enclosure balances heat dissipation with durability. Features a 4.3-inch high-definition IPS screen (800×480) with DC dimming and resistive touch for excellent outdoor visibility.
