Feature: 1. The frequency range of this product is from 50 kHz to 200 MHz, which is very practical. 2. This radio receiver supports all types of analog modulation: AM, SSB, NFM, WFM. 3. Powerful functions: variable filter width, adaptive noise suppressor, threshold noise suppressor, Noise Blanker, AGC, equalizer. 4. Use the full functional chip msi001, which is small and has good performance 5. The powerful stm32h743 with a clock frequency of 480 MHz is applied. Specification: Item Type: Radio Receiver Product Parameter Introduction: 1. The radio is constructed based on the SDR principle, and the function is determined by the loaded software. 2. The frequency range is from 50 kHz to 200 MHz (default version) / from 50 kHz to 250 MHz, 400 MHz to 2 GHz (registered upgrade version). 3. All Types Of Analog Modulation: AM, SSB, NFM, WFM; 4. Powerful Functions: Variable filter width, adaptive noise suppressor, threshold noise suppressor, Noise Blanker, AGC, equalizer. 5. Use the full functional chip msi001; 6. The powerful stm32h743 with a clock frequency of 480 MHz is applied. 7. 3.5 inch IPS display with touching screen. 8. There is a built-in UHF. 9. Control 2 encoders with buttons and touching screen. 10. The power supply is supplied by the external TYPE-C (Huawei mobile phone) interface and can be charged by TYPE-C. The internal battery voltage is 3.7V and the capacity is 2500ma. 11. When consuming headphones, the current is 300mA. 12. Built-in receiving module In order to improve the HF reception on the antenna, an additional board with a source follower has been developed. The board will be built into the standard receiver design. 13. Connect to the computer via USB, you can transmit CAT, IQ and audio. 14.160 kHz span, with scalability. 15. Sensitivity-Under the condition of up to 250MHz, s / w is 0.3μV = 10dB. 16. Due to the characteristics of the msi001 chip used, the dynamic blocking range is about 85dB. 17. With backlight control. 18. SMA female antenna socket; 19. Appearance Size: 102 x 74 x 29mm / 4 x 2.9 x 1.1in (excluding protrusions). 20. Weight: Approx. 240 g / 8.5 oz. Package List: 1 x Radio Receiver1 x USB Cable Note: The default standard configuration is only the host; other chargers and antennas are separately equipped.Register the upgraded version to broaden the frequency and increase CW decoding and other functions.
