Malachite SDR Radio Malahit DSP SDR Transceiver Receiver with Touching LCD Screen 50k-2GHZ Black Universal Tool for Home

Product Information

One could easily argue that the numerous signal processing and other flexibilities of the Malahit make that decision for you. While the Belka DX is superior in many respects, it lags behind the Malahit on sheer number of settings, though the Belka’s fixed processing positions are more than sufficient for superb reception on shortwave.

I also bought it with a view to using it as a piece of test equipment for locating noise sources with a WD8DSB mini-flag antenna. For my personal interests, the combination of a Malahit, Afedri SDR, and Belka DX for now fill all of my needs for experimentation with these small standalone radios. It will certainly be interesting to see where things stand at about this same time in 2022. The Malahit team has made a change in the SMA cable – whereas before an extremely short length of wire attached the antenna to the PCB board, there is now a longer, though it appears even thinner, length of wire making that connection. A valid product review is one where you have experience or knowledge of the product that you would like to share with others. And these are far from all and only major points that I remember after watching radio presentation by Georgi (RX9CIM)

The results are clear – with all the bells and whistles that a Malahit offers in terms of signal processing – it is often much easier to get comfortably listenable audio from a portable made for shortwave listening than with the Malahit.

Something the pc can actually see if I disconnect the usb cable, this wording “STM Device in DFU mode” disappears. I understood that the problem is because “MALAHIT RECEIVER DFU” does not appear but “STM Device in DFU mode”. It does NOT scan or search. Notwithstanding that, bearing in mind it fits into the palm of a hand, it is a very clever machine indeed. There are 50 programmable 'memories'. However, although recent firmware updates appear to have helped reduce the level of noise spikes from 50 kHz up through the shortwave bands, the receiver remains hobbled to a degree by this internally-generated noise. That is not something seen on direct competitors of the DSP-2, such as the Belka DX and Afedri LAN-IQ. For HF listening I use my Malahit with a specially designed PA0RDT mini-whip which runs off the Malahit’s internal Bias-Tee.Main chip ARM STM32H743VIT6 MCU High-performance and DSP with DP-FPU, ARM Cortex-M7 MCU with 2MBytes Flash, 1MB RAM, 400 MHz CPU Importantly that Georgi already released next generation of his radio DSP2 which he is selling now, with second board of automatic filters getting this radio to the next level.

I tapped on every menu option in every category. All work as advertised, even ones I did not fully understand. Noise reduction is extraordinary. No obscenities, discriminatory, abusive, or other content not suitable in public or for younger readers. Do not submit a product review critiquing another review or reviewer. Reviewers should be able to share their product opinion without being publicly criticized. If the Malahit team can come up with changes in the future that help improve the receiver when used with a whip antenna, beyond the option of activating the 50 ohmAt every point when testing the Malahit, I have concluded my sessions by taking a Tecsun receiver – 990x, 501x, PL-330 and 368 – and comparing them in terms of basic listenability, to the Malahit. I have used some older classic portables – SONY SW-77, ICF-2010, SW-100, Panasonic RF-B65, even a SONY ICF-7700 (a mostly forgotten basic portable) and tuned in the same signals. Over on the SWLing.com blog we've seen news about the release of a new Russian designed and made portable software defined radio called the "Malachite-DSP". The Malachite-DSP is an "all-in-one" portable SDR that is controlled via a touch screen and two control knobs. It covers 0.1 MHz to 1000 MHz with a bandwidth of up to 160 kHz, and the custom software supports all common modulation types. The whole device consumes 300mA and is powered by a Li-ion cell. It's marketed as a modern DEGEN and TECSUN replacement, so it appears to be targeting the HF short wave listening (SWL) customer. Powered by an external TYPE-C (for Huawei mobile phone) interface or battery (built-in 3000mah lithium battery), which can be charged by TYPE-C My particular DSP-2 unit went dead after an update to an early version of the 2.10TEST firmware. At the time, I had spoken via Skype with Georgiy on the Malahit team and kept up a string of communications on the Malahit Telegram channel. Georgiy of Malahit team suggests that best performance on shortwave will be achieved with a normal longwire antenna, or a wire of at least two meters. Through a series of firmware updates, the Malahit team has been playing a cat and mouse game, attempting to reduce noise across the spectrum. At some point, a limit is reached in terms of what can be achieved with the existing design.
