DSP SDR Radio Receiver 4.3 Inch 100KHz To 149MHz FM MW SSB CW HAM Shortwave Radio Receiver Portable Shortwave Radio

Description:

The product is based on for Tayloe Quadrature Product Detector method to achieve frequency mixing. The clock generator Si5351 generates two variable frequency orthogonal square wave signals as excitation, achieving an ultra low noise ZIF zero intermediate frequency receiver. The IQ signal obtained after mixing is output to the CODEC and collected by the MCU, where the DSP algorithm completes signal demodulation and display. 

Features:

1. PORTABLE RECEIVER:
This DSP digital demodulation receiver, based on SDR software defined radio architecture, has 192kHz wide spectrum and waterfall display capabilities, combined with 16bit sampling could achieve CW, AM, SSB, FM, WFM demodulation functions.

2. EXCELLENT RECEPTION EFFECT: 
This full frequency band amateur radio receiver is equipped with powerful DSP chip and a long retractable antenna, with excellent signal quality, can receive various channels without any interference.

3. LCD DISPLAY: 
The SDR receiver adopts all aluminum alloy CNC shell, equipped with 4.3 inch 800x480 resolution high brightness IPS LCD display.

4. COMPATIBLE HEADPHONE: 
With a compact size of 14x7.4x2.2mm, you can take it anywhere. Supports regular 3.5mm headphones or CTIA (US standard) interface headphones.

5. HIGH CAPACITY BATTERY: 
Built in 5000mAh 3.7V battery, can be used for about 10 to 12 hours (depending on the volume and brightness settings of the machine).

Note:

1. This machine adopts an SDR architecture. If there is a strong transmitting station near you, there may occur cross station or mirror station. Please be aware.
2. The input impedance of the antenna interface is 50Ω. For medium wave radio stations, it is recommended to connect a dedicated medium wave ring antenna externally to achieve better results.
3. Before listening with headphones, please pay attention to the earphone (EAR) volume setting to prevent discomfort caused by excessive volume.
