A. Based on SDR architecture, the msi001 RF front - end is used for 12 - bit quantitative sampling, using the stm32h743 processor, with a main frequency up to 480mhz. B. It can receive frequencies from 50 kHz to 49.999 MHz, 50.001 MHz to 249.999 MHz and 400 MHz to 2 GHz. C. The sensitivity is around 0.2 - 0.3V. D. The anti - blocking performance is about 85 dB. E. The real - time sampling bandwidth is approximately 160 kHz. F. It has features such as variable filter, adaptive noise reduction, noise reduction, and noise suppressor. G. The display is an IPS 3.5 - inch capacitive touch screen with backlight adjustment. H. The working current should not exceed 300 mA. I. There is a dual - antenna input option version, with a front - end attenuation filter module having an attenuation up to 30 dB, high - resistance input, short - wave sensitivity, and four additional front - end filters. J. It can connect to a computer via USB for IQ and audio communication. K. Product Name: Radio Receiver L. Display size: 3.5 inches M. Interface: USB N. Battery capacity: 3000 mAh O.
