This is the smallest SDR radio I've ever had. Fits in the pocket and at the same time has very wide frequency range 50kHz-2GHz. All analog modes AM/NFM/WFM/SSB/CW included. It decodes RDS in WFM broadcast stations. This one is the chinese copy/clone based on an original famous russian SDR project "Malachite-DSP". All the features mentioned above requires to purchase and install the original firmware update from a russian "Malachite-DSP" team. The price for activation code is approx.50USD. - Where to buy this receiver: https://www.banggood.com/Ultra-thin-50KHz-200MHz-Malahit-SDR-Receiver-Malachite-DSP-Software-Defined-Radio-3_5-inch-Display-Battery-Inside-Nice-Sound-Black-400MHz~2GHz-p-1789700.html - Firmware upgrade (complete informations): https://radioamateur.us/malachite-dsp-software-update/ - STM DFU Programmer: https://www.st.com/en/development-tools/stsw-stm32080.html - Latest original firmware download: https://yadi.sk/d/4ZgsrswxYClG1Q/%D0%9F%D1%80%D0%BE%D1%88%D0%B8%D0%B2%D0%BA%D0%B8(FIRMWARE) - Buy/ask for official firmware (activation code) on this email: rx9cim @ rambler.ru - Antenna used in this video: http://www.sk-tech.sk/om0et/ultralight-mla-ver.4.html - N9EWO Review of the original Malachite-DSP: https://www.qsl.net/n9ewo/malahit.html - China Malahit / Malachite Users Facebook Group (very helpful): https://www.facebook.com/groups/2673986352928589/ This is not a promotional video.
