Many thanks to SWLing Post contributor, Dan Robinson, who provides this update to his article on the Belka DSP receiver. Dan writes:
One of the other DSP radios shown being demonstrated on YouTube is this one by Georgy Yatsuk, presumably from somewhere in Russia. In his comments posted on January 14th, Fernando Duarte who runs the FENU site says:
“This little gem makes a name for itself. Everyone wants it. But it is still difficult to get. Georgy Yatsuk (RX9CIM) developed this small portable SDR with two of his colleagues. What this little guy offers is simply phenomenal! -Frequency range: 50KHz-2GHz -All important types of operation -160KHz wide waterfall & spectrum display zoomable -Noise reduction adjustable -Noiseblanker adjustable -Equalizer for adjusting the timbre – Controllable via PC -Control via CAT -etc, etc … Because the firmware is still in full development, certain functions will definitely be added. A test and a detailed presentation will be available on my website in the near future. Stay tuned !!”
As of this moment there is no additional information as to whether this seemingly excellent receiver will ever become available and in what numbers.
Many thanks for this update, Dan! We published a post about the Malahit-DSP in November on a tip from H. Garcia (PU3HAG). I have put in an inquiry to purchase one to evaluate here on the SWLing Post as well. This does look like a fascinating portable SDR!

Some very exciting news on the topic of portable all-band receivers comes from Russia! A group of engineers have just released for ordering the new Malahit-dsp. And it’s truly impressive! Picture an Icom IC-R8600 with the size of a Sony 7600G!
It seems it all started in June this year. Back then, RX9CIM George posted a note in QRZ.com forum about a new project he had been working of a standalone, SDR-based, all-band, all-mode receiver called Malahit-dsp.
Fast forward to November and it seems the project is finally complete as new posts started to bubble up in Youtube and in Russian forums. George is now taking orders of the Malahit DSP.
I can’t read Russian, but with the help of Google Translator, we can find some interesting details:
The project authors are RX9CIM George, R6DAN Vladimir and R6DCY Vadim. It seems their goal was to design a low-cost portable SDR radio, using only easily obtainable components and to become the natural successor of the popular Degen and Tecsun radios.
- 1 MHz to 1000 MHz.
- Bandwidth 160 kHz.
- Modulation types AM, WFM, NFM, LSB, USB.
- Powered by one Li-ion cell.
- Consumption up to 300 mA
- Main chip ARM STM32H743VIT6 MCU High-performance and DSP with DP-FPU, ARM Cortex-M7 MCU with 2MBytes Flash, 1MB RAM, 400 MHz CPU
- Printed circuit board is used four-layer, factory-made; for purchase, refer to RX9CIM. [email protected]
PCB only: ~ USD 17.22
Finished receiver delivered inside Russia: USD 195.65
From the forum, there is also this important note: “Attention! Fraud/Scammers detected! You can purchase components or finished devices from George only ”
It seems the project is open source, the schematic, PCB and software are available to download.
I really hope this receivers becomes popular and available world wide. I also hope this new project “shakes” a bit the industry of shortwave receivers. Since the Degen 1102/03, Tecsun 450/600, Tecsun PL310/880, we have been seeing only iterations of the same designs.

Recent discussion on Malahit, annoucement of ordering is now available, pictures and videos
Video 1: Shows the soldering of large components (encoders, speaker, SMA jack) on the radio board and installing it into the metal enclosure. Next a demo of receiver working. Prepared by Sergeyenkov Alexander:
Video 2: It shows a bit of the manufacturing process and demonstrates how one can build the receiver at home using kit pre-made board and components acquired in AliExpress. Also includes a test of the receiver barebones. Prepared by R2AJI Vladimir on his YT channel “HAM Radio Channel”
Wow! Thank you so much for sharing this! The Malahit-DSP looks like a fantastic little receiver–I especially love the fact that it has a backlit color touch screen with both a responsive spectrum and waterfall display. It also looks and sounds like the built-in speaker is of decent quality and the audio amplification is more than adequate.
I’ll see if I can get one to evaluate. Thanks again for the tip!
