HamGeek DSP-01 4.3" SDR Radio Receiver DSP Digital Demodulation CW/AM/SSB/FM/WFM

Description: Description Software Defined Radio SDR Radio Receiver DSP Digital Demodulation CW/AM/SSB/FM/WFM w/ 4.3" IPS LCDAttention:This product is neither an instrument nor a professional radio. Compared with the former two, the receiving performance will be slightly inferior. Your order represents that you have a certain understanding of the technical implementation and functional limitations of this product, and may need to take certain risks. For example, returns and exchanges caused by products that cannot meet your psychological expectations.This product realizes frequency mixing based on the Tayloe Quadrature Product Detector method. Clock generator Si5351 generates two quadrature square wave signals with variable frequency as excitation, and realizes an ultra-low noise ZIF zero-IF receiver. The IQ signal obtained after mixing is output to the CODEC codec and collected by the MCU, and the DSP algorithm in the MCU completes the demodulation and display of the signal.Tayloe mixer references:Ultra Low Noise, High Performance, Zero IF Quadrature Product Detector and PreamplifierDescription:HamGeek DSP-01 is a DSP digital demodulation radio based on SDR architecture. It features a 192kHz wide spectrogram and waterfall display. With 16bit sampling, it is a high dynamic receiver with CW, AM, SSB and FM demodulation functions. The whole machine adopts all-aluminum alloy CNC shell, with a 4.3-inch 800x480 resolution high-brightness IPS LCD display. It also maintains a compact and compact body.Immediately take it to the outdoors, enjoy the natural scenery and the fun of the radio anytime, anywhere!Base Parameters:- Display technology: 4.3" IPS 800x 480; DC dimming bright LCD- Control method: resistive touch screen + rotary encoder- Frequency range: 100k~149MHz- Working mode: CW, AM, SSB (LSB/USB), WFM, FM broadcast stereo (requires headphones)- Step frequency: 1Hz/10Hz/100Hz/1kHz/10kHz/100kHz/1MHz/10MHz- Spectral bandwidth: 192kHz, 128kHz, 64kHz, FFT real-time spectrum display- Antenna interface: BNC male connector, input impedance 50Ω, maximum input power -20dBm- Reference crystal: TCXO 26MHz ±0.5ppm- Audio interface: support ordinary 3.5mm earphone and CTIA (American Standard) interface earphone- Speaker power: maximum 3W, 4Ω multimedia speaker- Charging port: USB Type-C, 5.0V/2A- Current consumption: about 250mA at 5V- Battery capacity: 5000mAh/3.7V, 18.5Wh, lithium battery- Usage time: about 10-12 hours, depending on its volume and brightness- Channel saving: Preset 99 channels Chinese station name, station frequency and demodulation mode- Dimensions (without protrusions): 136 x 74 x 22mm/5.4 x 2.9 x 0.9" (LxWxH)- Main unit weight: about 310g/0.7lbReceiver Parameters:- Gain of RF front-end power amplifier: fixed 20dB- Circuit Type: Zero-IF ZIF- Side-band suppression: ≥55dBDisplay Control Parameter List:12 optional parameters for the encoder:1.
