Feature:1. [Touch Screen] DSP SDR receiver is IPS 3.5 inch display with backlight adjustment capacitive touch screen. Variable filter, adaptive noise reduction, threshold noise reduction, noise suppressor, AGC, etc.2. [High Performance] This DSP SDR receiver is based on SDR architecture, msi001 RF front end for 12 bit quantitative sampling, using stm32h743 processor with main frequency up to 480mhz.3. [Receiving Frequency Range] The shortwave radio receiver receives frequencies from 50 kHz to 49.999 MHz, 50.001 MHz to 249.999 MHz and 400 MHz to 2 GHz. Demodulation types are am, SSB, NFM, WFM, CW.4. [With Filter] Dual antenna input option version, front end attenuation filter module, attenuation up to 30dB, high resistance input, improved shortwave sensitivity, adding four additional front end filters.5. [Support USB Connection] This radio receiver can be connected to a computer via USB, allowing cat, IQ and sound communication. Uses PCB housing to provide better RF performance.Specification:Item Type: DSP SDR ReceiverMaterial: PCB, LCDScreen: 3.5 Inch IPSProcessor: Stm32h743Sampling Rate: 12 BitSampling Bandwidth: 160KHzReceiving Frequency: 50Khz-2GHzDemodulation Type: Am, SSB, NFM, WFM, CWReceiver Battery Type: 3600mAh Li Ion Battery (Built in).Package List:1 x DSP SDR Receiver Host1 x 0.1MHz to 6GHz Low Noise Amplifier Module 1 x Type C Cable1 x USB Cable 2 x Antenna2 x Expansion Board4 x Screw2 x Metal Studs
