Specification:1. The radio is constructed based on the SDR principle-the function is determined by the loaded software;2. Frequency range: from 50 kHz to 200 MHz (50KHz-250MHz and 400 MHz to 2 GHz after registration)3. All types of analog modulation: AM, SSB, NFM, WFM;4. Powerful functions: variable filter width, adaptive noise suppressor, threshold noise suppressor, for Noise Blanker, for AGC, equalizers;5. Use the cheap but fully functional chip msi001;6. The powerful stm32h743 with a clock frequency of 480 MHz is applied;7. 3.5-inch IPS display with touches screen;8. There is a built-in UHF;9. Controls-2 encoders with buttons and touches screen;10. The power supply is supplied by an external TYPE-C interface or a battery (need to be provided by the user) and can be charged by TYPE-C. The capacity of the battery is not less than 1500mA/h.11. Consumption-300mA when listening to headphones;12. Reception on the built-in telescope or external antenna In order to improve the HF reception on the telescope 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 through 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 0.3V = 10dB; the limiting receiving sensitivity is almost close to -140dbm16. For DSP filter adjustment range: 0-10KHz (adjusted to 50Hz-3KHz voice clarity and anti-interference ability are preferred)17. Due to the characteristics of the msi001 chip used, the dynamic blocking range is about 85dB.18. With backlight control;19. SMA female antenna socket;20. Motherboard size 100X70mm (excluding protruding rods)21. Mainboard weight 75g22. Frequency range-from 50 kHz to 200 MHz (default version)includes:1 x Receiver
