THE MALACHITE-DSP: A $195 RUSSIAN MADE PORTABLE WIDEBAND SDR RECEIVER WITH TOUCH
SCREEN

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.

Production appears to be small, with purchasing currently done by contacting
RX9CIM, one of the project creators, directly at his email address (details on
this forum post). The cost for a fully assembled unit is 12500 Russian Rubles
which is 195 USD (not including international shipping). You can also purchase
just the PCB without components for 1100 Rubles (17 USD). Importantly the forum
post notes to watch out for scammers, who appear to be trying to take fake
preorders for the device.

From the components list we can see that this SDR runs on the MSI001 tuner chip,
which is the same tuner chip used in the SDRplay line of units. However, unlike
the SDRplay units which use a wideband MSi2500 ADC, the Malachite-DSP uses an
audio chip as the RF ADC. This provides a 16-bit ADC, resulting in high dynamic
range, but at the expense of the available bandwidth which is only 160 kHz.
A STM32H743VIT6 with ARM Cortex A7 processor runs what appears to be custom DSP
and GUI software. The software doesn't seem to support DRM, but AM, WFM, NFM,
LSB, USB are all supported.

The main place for news and discussion on the Malachite-DSP appears to be on a
Russian ham radio forum thread. Judging by the fact that the schematic, software
and BOM is all freely released, the project appears to be open source. There is
also a group on the Russian Facebook clone vk.com where some discussion is
occurring.

The YouTube videos below are by a Russian reviewers. Be sure to turn on the
YouTube closed captioning and auto translation feature if you want to follow
along in English.

The Malachite-DSP reminds us a bit of the unreleased PantronX Titus II SDR,
which is supposed to be a low cost (aiming for less than $100 USD) 100 kHz - 2
GHz tablet screen based SDR that was supposed to make DRM reception more
popular. However the Titus II hardware has never eventuated since it's initial
news in 2016, and at this time appears to be a dead project.

Junk quality unit can be purchased for $35 on walmart.com
Original but second generation DSP2 w/ filters great quality components can
be purchased from RX1CIM, just send email to malahit_sdr@rambler.ru to get
into waiting list. You’ll get it within month delivered for extra $14 to
US.

4. August 9, 2021 - 11:07 pm Michael Blanc

And Georgi is actually selling DSP2 now, you can order from original
developer RX9CIM and get lot better quality version of this radio vs clone:
– cheap and lot darker and not as sharp version of LCD w/ barely
functioning capacitive touch screen, doesn’t respond to every click as
Georgi (RX9CIM) mentioned that replacement is misaligned badly some
functions don’t respond and you have to click around control buttons to
find the functional spot.
– LCD connected to PCB with 3 times longer then original flat cable, making
radio noisier from digital signals getting into RF and waterfall looks lot
busier but reality is – it just own noise.
– cheap encoders responding to every 5 to 10th click
– Laser cut PCB fiberglass used on most of the cases vs aluminum quality
case.
– Audio codec chip used on clones is cheap model unlike original version.
Personally I care about ssb only but for some who also likes FM Stereo or
wide AM, could be significant.
– FW: basic demo is up to 200Mhz w/ minimal features, but 2 Ghz version
cost of the license paid to RX9CIM while chinese sellers sell cracked
version with upgrade to future versions questionable meaning that hope that
Georgi will be supporting future upgrades by intentionally making future fw
version compatible with clones..
– 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.
And these are far from all and only major points that I remember after
watching radio presentation by Georgi (RX9CIM)
To reserve your radio w/ about month of waiting time, as of now, simply
send mail to Georgi to malahit_sdr@rambler.ru English is ok.
While I have my own clone that I started with, I do NOT recommend to buy
obsolete model build with cheapest and lowest quality components on a
market. And it’s not worth the aggravation buying low quality build radio
with illegal FW which chinese sellers will charge you for cracked version
anyways and the price difference getting original radio is really not that
much, but the difference is HUGE!
73! To Everyone, hope this helps. Michael

Too bad I see this post that now I bought what I thought was a good
device, the original and it’s Chinese with exactly the issues you write …

i am an italian buyer and i am waiting for a shipment from russia bought
from Georgiy
RX9CIM malahit_sdr@rambler.ru.
Initially on July 8 it was sent by Russian post with the tracking number
CL083277721RU; then on July 16 the package was blocked at Russian customs
and returned to the sender. Then on July 20 the sender reported that they
had solved the problem with the Russian post office manager and sent the
package back with the tracking number EL046773514RU. The tracking shows
that on 23 July it was delivered to the Italian Post Office. The tracking
shows that from the day of departure (20 July) to 23 July he used several
postal couriers several times: RUSSIAN POST and the Chinese CAINIAO: the
latest is this CAINIAO. Contact Poste Italiane they know nothing about this
package and a tracking number appears at the Italian customs with this
number EL046773514RU. Beware of this type of purchase you may not receive
it

I want to make a correction to what happened, all the confusion was made
by the Italian Post Office because after the problem indicated, the
Russian colleague sent everything back with ordinary EMS. On July 21, the
package arrived in Italy Customer (customs) (as indicated in the Russian
Post tracking) but the Poste Italiane call center told me several times
with various operators that they did not find anything. When I asked if
by chance the package had been detained at customs, all the operators of
the Poste Italiane call center in unison told me that everything that
arrives first passes through them and then if it is outside the EU they
pass it through customs so they excluded the 100% possession by customs
indicating that the package had not really entered Italy, leading me to
believe that Russian post had lost it. By coincidence the Russian
colleague was also on vacation and therefore did not respond to emails.
Later in the last few days he contacted me apologizing that he was on
vacation and had no internet on the vacation spot. So all these
ingredients obviously misled me. Then I contacted RUSSIAN Post (they
immediately responded to all my communications and sent a communication
to Poste Italiane on 2 August to inform them that their hand delivery
took place on 21 July cm Obviously they gave the package to someone with
relative receipt of handover and these pulled into question had to take
it into account (the gnorri of Poste Italiane). In fact, magically on
August 3, then on the Italian Post Office a slew of backlog tracking
including all days 22 July 23 July 24 etc. .
I apologized to my Russian colleague (who is also an engineer) in which I
must say he was very understanding indeed he also sent me as an
attachment the copy of the shipping receipt that the Russian post office
gave him. it seemed only right to point out the clarification to whom I
told my experience: ultimately the Russian colleague is very reliable, as
well as his Russian postal system … and as usual the Italian Post Office
is running water on all sides and creating tragedies and
misunderstandings

How did you buy your DSP2? All I can find on the web is a Russian site
and I don’t speak/read Russian.

I feel I have to jump in on this statement… “Judging by the fact that the
schematic, software and BOM is all freely released, the project appears to
be open source”
First off, there is no legal definition of “open source”. There are Open
Source licenses, that describe explicitly what can and cannot be done with
artifacts like source code, design files etc., but just because these
things are available, no assumptions can be made.
Additionally, even if something has an Open Source license, this may not
always grant rights to use commercially, i.e. someone using the source code
and design files to have units manufactured, which they then sell on.
I have seen this lack of understanding used to justify purchase of a
cheaper “unofficial clone” of a project numerous times, and because someone
reads the words “open source” on a blog like this, they are happy to defer
responsibility and just pirate away.
Yes, this is a bit of a rant, but it’s something I feel strongly about, not
just on principle, but I have seen many producers of amazing projects just
lose interest and stop producing because their (reasonable, IMO) terms are
just ignored,

The Russians design and build some great products, but getting them to the
world is next to impossible. Putin needs to start puttin some work into
that problem.

I just received my Russian Malachite today. Great radio. Nice solid thick
case — well made. And the official firmware is a lot better than the
“test” firmware on my Chinese clone! But waited 2 months after order for
a radio to be shipped and then about 6 weeks for it to reach me in
Canada.

Did it come ready to go

Yes — it came ready to go except that I had two provide and install
the 18650 battery. It lacks the “optional board” which is now
available and I have ordered.

Funny that this guy doesn’t realize he has a potential goldmine on his
hands. He could set up a small production team and earn thousands of dollar
on the international market.

Hi, I found this on Amazon:

https://is.gd/Wd3V7t

Not much info provided But I searched online and found what looks to be the
same unit on Aliexpress. It has more details on the unit:

https://is.gd/BQUb6t

I am not sure…is this unit a “good” example…or is it representing the
“junk” version referenced in these comments?

Don’t buy the Chinese versions !! Put an extra $ 100 and you will have a
good, well tuned receiver with a one year warranty. In addition, if there
is a problem, Georgye easily responds by email.

OK. So how do I purchase the true radio — presumably from Russia? Web
site address ? e-mail address?

There is no website.
Write an email to Georgy -> malahit_sdr@rambler.ru
From there there is a queue and the delay is 2 months.

NOT AVAILABLE !!! I did an on-line translaion of the Russian manual to
English , but it is of very limited help. It is also not much good with the
Chinese crap flooding the ebait market with their hacked ( more like
slaughtered ) firm ware.
Beware..the Chinese JUNK being offered is JUNK …. &
JUNK IS JUNK. Firmware has been gutted and does not contain most of the
features shown and advertised .

Don’t be so stupid. That is the free demo firmware available for evryone.
If you want full functionalty you can buy commercial firmware. Write a
message to author with the code on your displat to
malahit_sdr@rambler. ru , malahit_activation@rambler.ru
Chinese’s receivers so cheap because it does not contain a price for
firmware. Russians RX will be expensive in twice.

OK. I have purchased a Chinese “Thicker” receiver on ePay. It seems to
work OK, but features are lacking. Also it lacks an internal battery.
One feature it seems to lack is the ability to key in a frequency. I
assume that this keyboard would also be used to key in an authorization
code if you want to upgrade the firmware. If so, how can you upgrade
it? Or is there way to purchase the proper Russian radio with the
complete firmware?

check the switch on the bottom. It is labelled “REST” and looks like
a pushbutton; however, it is a slide switch for disabling the
battery. Once you turn it on the battery will be connected.
I ran into this too and thought the battery was simply flat from
shipping, but when I looked close then I saw it, flipped the switch
and all was good.
This is information deemed “not important enough to tell the
customer” LOL

Thanks for your help! You are correct! Who I saw the REST switch, I
thought it was a RESET button! Sliding the switch activated the
internal battery.

As I said, I bought my radio from China. There were no instructions
provided. After I received it, I sent a message to the seller
asking him how to install an internal battery. He did not seem to
know that the radio already had an internal battery and said I
would have to modify it to accommodate an internal battery.

Thanks again!

ENGLISH MANUAL… DOES NOT EXIST! download Russian manual then try to convert
– it can be done , its not easy. Just gotmy Malachite “DSP_SDR ” from
china. WHAT A MESS! Firmware (HARD menu) is missing 12 of the 14 items
(FEATURES) it should have come with. The 4 items that are on the “HARD”
menu only two actually function. The firmware has been hacked and missing
features like: Frequency bar between spectrum & waterfall displays …not
there .Also missing is Freq. Calibration, , Spectrum Scale set , and about
another 10 features …all missing. The seller builder (china) then offers to
give you a code to flash so you can get the lost features (for a mere
$55.00 more ). The basic receiver is VERY difficult to tune. <oving the
Frequency digit cursor is a challenge and even once adjusted I find the 2
meter repeater frequencies are randomly from 25 to 95khz off , with no way
to correct. The list of short comings goes on and on. These EBAY – CHINA
units are definately not ready for prime time.
New units have started to appear on Ebay with direct frequency entry but no
information as to what is on and what is not on the GUI. I suspect still no
frequency bar display. Pay your money and take your chances. What could
have been a real neat receiver is just a toy and not a very good one at
that.

That is not “hacked” firmware, that is a free Demo firmware. Buy in
additionally a full futured firmware from russian designers.

What does D and F stand for,, DECEIVE and FAKE? The3 DEMO version of
firmware is a joke , and a bad one at that. It is a come-on to get the
CHINESE hand in your pocket for an extra $55 or so. They BAIT you with
features in their pictures then after purchase they ask if you want to
flash some “real Russian” firmware. This is no more tha ntheft…AVOID IT
!

i am an italian buyer and i am waiting for a shipment from russia;
initially on July 8 it was sent by Russian post with the tracking number
CL083277721RU; then on July 16 the package was blocked at Russian customs
and returned to the sender. Then on July 20 the sender reported that he
had solved the problem with the director of the Russian post office and
sent the package back again with the tracking number EL046773514RU. The
tracking shows that on 23 July it was delivered to the Italian Post
Office. From the tracking we can see that from the day of departure (20
July) to 23 July it has used several postal carriers several times:
RUSSIAN POST and the Chinese CAINIAO: the latest is this CAINIAO.
Contacted Poste Italiane they know nothing about this package and it
results to the Italian customs a tracking with this number EL046773514RU

Stop confusing the real Russian Malahit receiver with the Chinese Malachite
copies !! It’s not the same thing ! The Russian receiver covers from HF to
UHF. I own one.

GOOD FOR YOU. The seller in china purchases his boards from Russia then
loads his own hacked firmware . READ the article again before commenting
and exposing your stupidity further ~~~

Appena ricevuto Questa radio, assemblata, dalla Cina. Non c’è allegato un
manuale di istruzione. Ho provato quasi tutti i comandi, ma non sono
riuscito a capire come cambiare il modo della modulazione. Non c’è un tasto
“MODE” dedicato come ho visto in altri apparati su You Tube. Qualcuno mi
può aiutare? Grazie

Premi la rotella del volume e quella delle frequenze per cambiare la

Unique and cool device. It’s a pity that so far there is no serial
production for this thing. You need to contact manufacturer by email and
gather support information and manuals through russian forums.
http://hamforum.ru/viewtopic.php?f=19&t=193
It seems manufacturer is really busy because device is quickly gaining
popularity.
Hopefully manufacturing and marketing process will improve soon. Would get
one for myself.
