1) The radio is built on the principle of SDR-the function is determined by loaded software 2) Frequency range: from 50 kHz to 200 MHz (default version), users can contact website to upgrade from 50 kHz to 250 MHz, 400 MHz to 2 GHz 3) All types of analog modulation: AM, SSB, NFM, WFM 4) Powerful functions: variable filter width, adaptive noise suppressor, noise suppressor, for Noise Blanker, , equalizer 5) Use cheap fully functional chip msi001 6) The powerful stm32h743 with a clock frequency of 480 MHz is applied 7) 3.5-inch IPS display touch screen 8) There is a built-in UHF 9) Controls: 2pcs; encoders with buttons and touch screen 10) It is powered by an external TYPE-C (for mobile phone) interface or battery (battery is not included), which can be by TYPE-C. 11) Consumption: 300mA when to headphones 12) The reception on built-in telescope or external antenna is to the HF reception on telescope antenna, and an additional board with source follower has been developed. The board will be built into standard receiver . 13) Connect to computer via USB, which can transfer , IQ and audio. 14) 160 kHz span, with scalability Advantages: 1. 3.5-inch capacitive screen 2. 4-layer board structure, higher performance than two-layer PCB 3. Adopt a sound unit, 2 vibrating , the speaker comes with a sound , the bass sound quality is full Model Number: SDR Receiver Usage: Home DIY Firmware: 1.10c Name: DSP SDR Receiver Screen: Capacitive touch color:As shown Material:metal+plastic Package Contents: 1 x DSP SDR Receiver 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.
