Improved The Graphical Display Of The Spectrum, Improved The Algorithm Optimization, And Increased The Display Speed Added The Function Of Determining The Activation Type - Just One Or Three Clicks On A Single Machine. One Push Activation If Pd15 (Pin 7 Of Reserved Field) Is On. If This Pin Is Closed To The Common Wire, It Opens With Three Clicks, Improved Hard Menu Improved Battery Indication - Voltage Is Displayed On Top Of The Picture Added The Use Of Discrete Signal Pd14 (Pin 8 Of The Reserved Field) To Control The User Equipment Function A Button For Switching Audio Output Has Been Added To The Hard Menu, He Copied The Audio Output Switching. Made According To User'S Request. Description: 's DSP SDR receiver capacitive touch screen, Flash via USB cable; Default frequency range: 50KHz-200MHz; Demodulation modes: AM, SSB, NFM, WFM Color: Black Material: aluminum alloy Product parameters: 1) The radio is built on the principle of SDR - the function is determined by the loaded software; 2) All types of analog modulation: AM, SSB, NFM, WFM; 3) Powerful functions: variable filter width, adaptive noise suppressor, threshold noise suppressor for noise blanker, , equalizer; 4) Use the cheap but fully functional chip msi001; 5) Use a powerful stm32h743 with a clock frequency of 480MHz; 6) 3.5 inches IPS display touch screen; 7) With built-in UHF; 8) Controls: 2; encoder with buttons and touch screen; 9) External TYPE-C ( mobile phone) interface or battery (battery not included) power supply, can be through TYPE-C. 10) Consumption: 300mA when listening to headphones; 11) The reception of the built-in telescope or external antenna is to improve the HF reception of the telescope antenna, and an additional board with an active follower was developed. The board will be built into a standard receiver design. 12) Connect to computer via USB to transmit , IQ and audio. 13) 160 kHz span with scalability; 14) Due to the characteristics of the msi001 chip used, the dynamic blocking range is about 85dB. 15) With backlight control; 16) SMA female antenna socket; 17) Motherboard size: 100 x 70mm (excluding connector size). 18) Built-in battery: 2500mAh Package Contents: 1 x SDR Radio Receiver 1 x Type-C Charging Cable 1 x Antenna Adapter 2 x SMA To M Socket 1 x Screen Cleaning Cloth Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
