Feature: 1. Impedance Matching: The main board PCB uses four layer circuit board process, and perform impedance matching on the circuit 2. Good Quality Sound Cavity: The screen backlight can be controlled, using good quality sound cavity with a bass diaphragm, and adopt SMA antenna socket 3. 0.3μV Sensitivity at 250MHz: Due to using the for msi001 chip used, the dynamic blocking range is about 85dB, and the sensitivity is 0.3μV at 250MHz 4. 3.5in Touch Screen: 3.5in IPS display with touch screen, screen display bandwidth is 160kHz, and support zoom display 5. Transmit CAT, IQ and Audio: The operation mode includes two EC11 pulse encoders and capacitive touch screen. Connect to the computer via USB, can transmit CAT, IQ and audio 6. Improve Receiver Dynamic Range: Built in LNA is used to improve the dynamic range of the receiver, and an expansion board is designed to improve the shortwave HF band. The board will be built into the receiver 7. Variable Filter Width: Possess variable filter width, used as adaptive noise suppressor, threshold noise suppressor, noise blanker, AGC, equalizer, support UHF band 8. Support AM, SSB, NFM, WFM, CW Demodulation: The processor core uses for STM32H743 with a main frequency of 480MHz, and support the analog modulations include AM, SSB, NFM, WFM, CW Specification: Item Type: SDR Receiver Material: PCB Frequency Range: 50kHz-2GHz RF Front End: For msi001 Battery Capacity: 2000mA/h Battery Model: Lithium battery Receiver Power Consumption: 300mA. Package List: 1 x SDR Receiver1 x Antenna Note: The receiver is based on the SDR principle structure, and the function is determined by the loaded software.
