Feature: 1. ULTRA LOW NOISE: This product is based on the for Tayloe Quadrature Product Detector method to realize frequency mixing, and the clock generator Si5351 generates two orthogonal square wave signals of variable frequency as the excitation, realizing an ultra low noise ZIF receiver. 2. IQ SIGNAL: The IQ signal obtained after mixing is output to CODEC codec and captured by MCU, and the demodulation and display of the signal is accomplished by DSP algorithm in MCU. 3. DSP DIGITAL DEMODULATION RADIO: For DeepSDR 101 is a DSP digital demodulation radio based on SDR software defined radio architecture. 4. DEMODULATION FUNCTION: With 192kHz width spectrogram and waterfall display capability, together with 16bit sampling, it realizes a high dynamic receiver with CW, AM, SSB, FM demodulation function. 5. ALUMINUM ALLOY: Shortwave radio receiver is made of full aluminum alloy CNC casing with 4.3 inch 800x480 resolution high brightness IPS LCD display, while maintaining a small and compact body. Specification: Item Type: Shortwave Radio Receiver Display Technology: 4.3‑inch IPS 800x480 Resolution DC Dimming High Brightness LCD Control: Resistive Touch Screen, Rotary Encoder Frequency Range: 100kHz to 149MHz Operating Modes: CW, AM, SSB Single Sideband (LSB, USB), WFM, STE (FM Radio Stereo, Headphones Required), I/Q Step Frequency: 1Hz, 10Hz, 100Hz, 1kHz, 10kHz, 100kHz, 1MHz, 10MHz Spectrum Bandwidth: 192kHz, 128kHz, 64kHz, FFT Real Time Spectrum Display Antenna Interface: BNC Male, Impedance 50Ω, Maximum Input Power ‑20dBm Reference Crystal: TCXO 26MHz ±0.5ppm Sound Interface: Support for Ordinary 3.5mm Headphones Or CTIA ( US Standard ) Interface Headset Speaker Power: Maximum 3W, 4Ω Multimedia Speaker Speaker Charging Port: USB Type C, 5.0V 2A Current Consumption: Approx. 250mA and 5V Built‑in Lithium Polymer Battery: 5000mAh Usage Time: Approx. 10‑12 Hours, Depending On Machine Volume and Brightness Settings Channel Saving: 99 Channels Can Be Preset, Preset Station Name, Station Frequency and Demodulation Mode Receiver: RF Preamplifier Gain: Fixed 20dB Circuit Type: ZIF Sideband Rejection: ≥50dB. Package List: 1 x Receiver1 x Charging Cable1 x Receiver Stick1 x Instruction Manual Note: 1. This machine adopts SDR architecture, if you have a strong broadcasting transmitter nearby, there may be a string of stations, mirror stations, please be aware of that.2. The input impedance of the antenna interface is 50Ω, for medium wave radio, it is recommended to connect a special medium wave loop antenna to get a better listening effect.3. Please pay attention to the earphone (EAR) volume setting before listening to use headphones to prevent discomfort caused by excessive volume.
