Adopt a sound unit, 2 vibrating chambers, the speaker comes with a sound chamber, the bass sound quality is very full. DSP SDR Receiver for Malahit. Capacitive touch screen. Flash via USB cable. Default frequency range: 50KHz-200MHz. Demodulation mode: AM, SSB, NFM, WFM. The radio is built on the principle of SDR-the function is determined by loaded software. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eFrequency range: from 50 kHz to 200 MHz (default version), users can contact official website to upgrade as 400 MHz to 2 GHz; All types of analog modulation: AM, SSB, NFM, WFM; Powerful functions: variable filter width, adaptive noise suppressor, threshold noise suppressor, for Noise Blanker, AGC, equalizer;Use cheap but fully functional chip msi001;The powerful stm32h743 with a clock frequency of 480 MHz is applied;There is a built-in UHF;Controls: 2pcs;encoders with buttons and touch screen. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eIt is powered by an external TYPE-C (for Huawei mobile phone) interface or battery (2000mAh battery is included), which can be charged by TYPE-C. Consumption: 300mA when listening to headphones; The reception on built-in telescope or external antenna is to improve the HF reception on telescope antenna, and an additional board with source follower has been developed. The board will be built into standard receiver design. Connect to computer via USB, which can transfer CAT, IQ and audio. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e160 kHz span, with scalability. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eSensitivity: Under the condition of up to 250MHz, s\/w is 0.3μV = 10dB; due to lack of measurement equipment, so the above measurements were not taken. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eAbout Touch Screen \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThis is a capacitive ISP screen \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eCapacitive touch has nothing to do with the screen material, the touch module is independent. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eMalachite responds to the same touch problems. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eFirst of all, the main control is a single-chip microcomputer, and the main frequency is only 480M, which cannot be as smooth as a mobile phone.  \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eIn addition,the touch will cause strong interference when working.  \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe firmware updated by the author reduces the refresh rate, so that the touch will not be so smooth.  \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eBesides,long press the volume key to turn off the touch function,turning off the touch signal interference will be greatly improved. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThere are certain skills in touch screen operation. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eFast click the screen can not let screen work,if you touch the screen about 1 second,it will work perfectly \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eColour: Black \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eMaterial: Metal+Plastic \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eSize: about: 99x69x32mm \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003ePackage Contents: \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e1 * DSP SDR Receiver for Malahit \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003c\/span\u003e\u003c\/div\u003e","brand":"mickcara","offers":[{"title":"Black","offer_id":41207558471817,"sku":"02621-1","price":211.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0365\/2131\/2393\/products\/8ae3e43ffaeb93402834ff5f3553bc45.jpg?v=1680073422","url":"https:\/\/mickcara.com\/fr\/products\/new-thicker-3-5inch-50khz-2ghz-malachite-dsp-sdr-receiver-malahit-sdr-shortwave-radio-receiver-firmware-1-10c-nice-sound","provider":"mickcara","version":"1.0","type":"link"}
