Portable software defined radio receiver with wide coverage and high fidelity performance. Designed for hobbyists and professionals who need accurate, flexible radio monitoring in a compact, rugged package. Key benefits Wide frequency coverage: 100 kHz to 149 MHz supports LW, MW, SW, AM, FM, WFM and Air-Band monitoring in a single receiver. True SDR and DSP performance: 16-bit sampling, advanced digital signal processing, and a 192 kHz real-time spectrum with waterfall deliver clearer demodulation and better signal separation for CW, AM, SSB (LSB and USB), FM and WFM. Clear, responsive display and control: 4.3 inch 800 x 480 IPS LCD with DC dimming provides bright, readable output. Control via resistive touch screen plus rotary encoder for precise tuning and fast operation in the field. Portable power and durable build: CNC machined all-aluminum alloy chassis keeps the unit compact and robust. Built-in rechargeable battery provides long runtime for portable use. Flexible audio and antenna interfaces: Standard 3.5 mm headphone jack with CTIA compatibility, internal speaker up to 3 W at 4 ohm, and a BNC male antenna connector with 50 ohm input and maximum input power -20 dBm. Technical highlights Frequency range: 100 kHz to 149 MHz Display: 4.3 inch IPS 800 x 480, DC dimming Demodulation modes: CW, AM, SSB LSB/USB, WFM, FM broadcast stereo (headphones required for stereo) Spectrum bandwidth: selectable 192 kHz, 128 kHz, 64 kHz with FFT real-time spectrum and waterfall Sampling: 16-bit sampling for high dynamic range Reference oscillator: TCXO 26 MHz +/- 0.5 ppm Tuning step options: 1 Hz, 10 Hz, 100 Hz, 1 kHz, 10 kHz, 100 kHz, 1 MHz, 10 MHz Antenna input: BNC male, 50 ohm, max input -20 dBm Audio: 3.5 mm headphone output with CTIA compatibility; built-in speaker 3 W max at 4 ohm Controls: resistive touch screen plus rotary encoder Form factor: compact, all-aluminum alloy CNC enclosure Why this unit solves common problems Consolidates multiple receivers into one compact device, eliminating the need to carry separate equipment for AM, FM, shortwave and aviation monitoring. Real-time spectrum and waterfall display make it faster to find weak signals and identify interference. Precise tuning steps and stable TCXO reference reduce frequency drift and improve repeatable tuning during long sessions. Durable metal housing and built-in battery enable reliable outdoor and mobile operation without external power. Practical use scenarios Field monitoring and portable DXing: Take the unit to parks, campsites or hilltops to hunt for shortwave stations, ham contacts and distant FM stations with real-time spectrum visualization. Aviation and public service listening: Monitor Air-Band communications and local VHF transmissions for situational awareness during travel or field operations. Amateur radio bench and workshop use: Use the receiver for band scans, antenna testing and signal identification while repairing or tuning equipment. What to expect in everyday use Quick startup and clear visual feedback from the high-brightness IPS screen. Smooth manual tuning with the rotary encoder or fast direct steps using selectable frequency increments. Clear audio through headphones or the built-in speaker and reliable demodulation across supported modes. Stable performance across bands thanks to advanced DSP processing and a precision TCXO reference. This receiver combines comprehensive frequency coverage, high-resolution spectrum analysis, and a rugged portable design to give reliable, flexible radio monitoring for hobbyists and professionals.
