Description
IWISTAO DSP SDR Radio Receiver 4.3 Inches 100KHz To 149MHz FM MW SSB
Model No: WSR-RA01
This product realizes mixing based on the orthogonal method of the Taylor product detector. The clock generator Si5351 generates two frequency - converted orthogonal square - wave signals as excitation to achieve an ultra - low - noise ZIF (Zero - Intermediate - Frequency) receiver. The mixed 101 signal is output to the codec, collected by the single - chip microcomputer, and the signal demodulation and display are completed by the DSP algorithm.
Features:
1. Portable Receiver:
This DSP digital demodulation receiver is based on the SDR (Software - Defined Radio) architecture, with a 192kHz wide spectrum and waterfall display capability. Combined with 16 - bit sampling, it can achieve CW (Continuous Wave), AM (Amplitude Modulation), SSB (Single - Sideband), FM (Frequency Modulation), and WFM (Wide - band Frequency Modulation) demodulation functions.
2. Good Reception Effect:
This full - band amateur radio receiver is equipped with a powerful DSP chip and a telescopic antenna. It has excellent signal quality, can receive various channels without interference.
3. Liquid Crystal Display:
The SDR receiver adopts an all - aluminum alloy CNC (Computer Numerical Control) shell and is equipped with a 4.3 - inch 800x480 - resolution high - brightness IPS (In - Plane Switching) liquid crystal display.
4. Compatible Headphones:
With a compact size of 14×7.4×2.2 mm, you can carry it around. It supports ordinary 3.5mm headphones or CTIA (American standard) interface headphones.
5. High - Capacity Battery:
It has a built - in 5000mAh 3.7V battery, which can be used for about 10 to 12 hours (depending on the volume and brightness settings of the device).
Specifications:
- Project Type: DSP SDR Radio Receiver
- Material: Aluminum alloy
- Display Technology: 4.3 - inch IPS 800x480 - resolution DC - dimming high - brightness liquid crystal display

- Spectrum Bandwidth: 192kHz, 128kHz, 64kHz, FFT real - time spectrum display
Antenna Interface: BNC male, impedance 50Ω, maximum input power -20dBm
-Reference Crystal Oscillator: TCXO 26MHz ± 0.5ppm
Audio Interface: Supports common 3.5mm headphones or CTIA (American standard) headphones
-Speaker Power: Maximum 3W, multimedia speaker 4Ω
-Charging Interface: USB Type C, 5.0V 2A
-Current Consumption: Approximately 250mA at 5V
-Battery Capacity: 5000mAh 3.7V (built-in)
-Usage Time: Approximately 10 - 12 hours, depending on the volume and brightness settings of the device
-Channel Storage: Can preset 99 channels, and can preset station names, frequencies, and alignment methods
Package List:
1 DSP SDR radio receiver
1 × Antenna
1 × Data cable
1 × User manual
Notes:
1. This device adopts the SDR architecture. If there are strong transmitting stations nearby, cross-stations or image stations may occur. Please note this.
2. The input impedance of the antenna interface is 50Ω. For medium-wave radio stations, it is recommended to externally connect a dedicated medium-wave loop antenna for better performance.
3. Before listening with headphones, please pay attention to the volume setting of the headphones (EAR) to prevent discomfort caused by excessive volume.
