Wow! That noise reduction setting is indeed impressive. Thanks as always for showing us all the cool radios, and other devices.
I have one of the original DSP 1's, the NR on the older model is equally as good as far as I've experienced. Malahit (and their knockoffs) have amazing noise reduction ability, only bettered by connecting to the PC and adding more tweaked noise reduction.
I have a non-licensed version, the Malhahit V3 and its noise reduction is also great, and so is its noise blanker. In fact, the only radio I have with a noise blanker as good as the Malahit V3 is an old Icom IC-R71A and a Yaesu FTdx- 3000. As for the noise reducion, none are as good, even the FTDx-3000.
Some things to remember when dealing with China and other clones: You must have the seller state what FW version (such as 1.10d or 2.40...etc) it has and ask if it is legal/upgradeable. DSP-2 receivers for those who are not aware, are the LAST model of the receiver using Russian-originated software. The actual Russian Malahit receivers are now at the DSP-3 model, with some significant improvements, including apparently changes to reduce noise from the screen. But ordering direct from Russia remains a challenge at this point. Chinese clone makers have done a very good job of adapting the Russian software to various designs and this is the latest one. The problem with all of these is that there are so many options available in the software for signal processing, such as PREAMP and other settings, that for listening to today's SW broadcasts, you're almost better off using a Tecsun 330 or 990 or H-501. Some people are confusing the MODEL of the receiver (DSP-2 for example) with the firmware (i.e. 1.10d). You're quite correct that build quality on this appears to be substantially better than other units online. And there are TWO antenna inputs which is a good thing, like the old V3 SDR which is still shown as being available online.
Well, the seller that I used states firmware version and that it’s licensed and upgradable, which is why I would recommend anyone interested in this item to use the links I provided.
That is confusing!
I've checked the Malachite Team website for the newer DSP3 and... got a bit frustrated. DSP3 is just DSP2 with (welcomed) incremental improvements: faster UI, less internal noise, USB-C connector.
I was hoping they already had for selling the DDC version. The DDC prototype was very promising, with several MHz of visible and IQ bandwidth and no-gap coverage.
I'm impressed with this. I'm looking to get one myself
How about let’s not buy things from Russia for the time being.
I just received mine two days ago, exact same one from Deepelec! Yesterday I made a video about how to upgrade the firmware to the latest 2.40 beta that adds FT8 and RTTY decoding. I was just thinking, it would be great if Tech Minds gets his hands on this model and makes a good video covering it, as there are not many videos on TH-cam about it! Well... guess you got one then haha! Amazing SDR receiver, great build quality!
Yeh, I’m actually quite blown away by the quality of this receiver. Everything from the actual casing to the receiver’s sensitivity. Definitely a good buy!
It seems a very complex method to upgrade firmware.
@@andynew2 Well I've seen easier methods for sure, but at least it is possible and explained well enough, so it's still a good thing in my book. The thing to be really careful about is to use the correct firmware file, as it can and probably will differ from clone to clone and also different from the original Malahit from Russia.
I bought a DSP SDR exactly the same as demonstrated it took ages to arrive I didn't know the country that made it, after making so checks I found out it was made in RUSSIA, and it's beautiful made in a grey metal case, wished I had left the screen protector on, but I removed it as the demonstrator did I must now get another screen protector, the radio arrived very well packed, and now I have to read the instructions that came with it, I am also a Radio Amateur and I have lots of ham radio friends in RUSSIA and also all over the world, I'm so glad I bought the radio the comment was written by Barry G4DIP!
Can't wait to get my official one ... thank you for your videos always good watching when I can't sleep
When you pressed that noise reduction button I genuilely exclaimed 'Holy shit!'
Glad you're so easily amused. But it deosnt' have multiple NR settings and no adjustable AGC-threshold which is critical in SDRs for reducing background noise. Try using an online SDR and look at the settings and then realize how lacking this device really is
@@624radicalham both the AGC and NR are adjustable
Incorrect. There is a 30 step Noise Reduction Threshold that is variable plus AGC Modes for Fast, Medium, Slow and Long settings with AGC Gain settings from 0 to 60 dB.
Thanks for this video. I currently own a licensed Malahit one but usually use it with a magnetic loop as the telescopic whip mainly picks up the display noise. This one looks worth the money.
73, and have a nice day!
I just got mine all the way from China. Took almost a month to get to the United States (Utah). I will say already that it is very good for the money! The only thing is all the birdies it generates but it doesn't generate any more than and other synthesized rig, really. Takes a day or two to figure out how to make use of it and optimize it for various bands. For example, the settings you might need to get good reception on AM (MW) would be a bit different than for the nearby shortwave (HF) bands. And VHF and UHF and broadcast FM music stations, all have their optimum settings you will have to fiddle with. I was amazed when I listened to my local AM station on 570 (KNRS in Salt Lake City) at night and could hear another station on 570 (co-channel interference) somewhere else in the USA. But with the Attenuation setting, I took the attenuation all the way up to 20 or so and got rid of the distant station entirely, as my local station was still very strong at 20 db Attenuation, whereas the distant station was no longer receivable. Very versatile and capable little rig! Lots of ways to clear up interference. I've never had a receiver (until now) sensitive enough to get that other 570KHz station from far away, so that says a lot. I only have good AM and SW reception with a High-Z antenna, which I happened to have and put to good use (Airspy YouLoop). Seems like anything below 30 Mhz needs a High Z but I have not tried a lot of other antennas yet so take that with a grain of salt at this point. I just got it the other day. The signal to noise ratio on civilian aircraft (118 to 137 mHz) and military aircraft (225 to 380mHz) is really good, better than my half dozen other radios that have those bands, including my Uniden SDS200. Good S/N ratio on weak air band signals is good to have. Also ham sounds great from HF SSB up the UHF.
Amazing little radio, does everything that my 3 racks full of older receivers does
Great small SDR radio! It’s looks so well built for sure. Impressive 😊
It looks like to be the new high-end standard for DSP receivers. Tons of controls and settings. Looks good to me!
Impressive radio. Love the colour waterfall, and clear audio with NR.
If this came out with a Yaesu or Icom badge, everyone would be beside themselves about how those brands had revived their tradition of great receivers. A quick request - could you put some specs in your videos?Ta.
Specs were shown at the start of the video, bottom left of screen. No point in reeling the whole spec sheet as I get winged at that I’m just reading a spec sheet. Links in the description to the products where the full specs are. I agree with you though, covering more specs would be good.
@@TechMindsOfficial Nice review and receiver, shame the next band starts at 404MHz only 4MHz less to receive Radiosondes (weather balloons.
Mine came into today. I am a very active Ham operator. Current main HF rig FTDX101MP and it has the best receiver for a transceiver in the world. So the bar was set really really high in receiver performance , filtering and noise mitigation etc. This thing blew me away, I don’t know how they did it. It’s that darn good.
101MP was top of the Sherman report, havnt checked in a while, but if you are comparing it to the 101MP and say its good, then it is :-) Thanks and hope you enjoy it. Matt
Since you know your radios , no it's not a 101MP or a 7610 etc in horrible conditions but in normal conditions it's at least as good as a 7300.But, in SWL radios, it is in a league of its own. Like your videos and content. Keep it up, thank you!
@@TechMindsOfficial
This is an impressive receiver. I've been looking for a "sensible" portable SDR receiver for airband and HF and this is it!
Also waiting for the X6100 mark 2....
That little radio sounds epic.. ideal for air shows!
Have just received mine .
Beautiful build quality , excellent performance and the audio is better than any of my other radios , including my NRD515 , Kenwood R5000 , Icom IC-R70 .
How much??
Thanks for the video. Gonna grab one for my travels when I am abroad for work in hotels and airports etc. The performance on that small telescopic antenna is wild!
Good choice!
Nice review :-) This radio is evolving into something really good, far surpassing the popular single chip superhets / baseband dsp radios.
Looks and sounds amazing!
Finally one that seems the most worth buying. Nice look as well..
Just been looking at one of these, great timing
Just ordered one... cant wait!
What a time to be alive!
Wow, excellent NR and the audio is fantastic..!!
That screen is outstanding.
Pretty slick. Price is amazing for what you are getting. I was expecting $1000. Look what it does and compare it to the eaton 750 at $600. This thing at $400 CDN is a steal.
Hmm nice audio but it should be for that price ! I would have liked to seen a MW and LW scan with it using a loop or just the whip etc plus RDS reception on FM. Yes the NR does a good job also with my Malachite V5 clone
Fantastic equipment! 👏👏👏 Thanks for the video. 🙏
Impressive for its compact size!
The noise reduction on 40 worked awesomely ! The other day 40 was a bit noisy for me and I hit the NB button on my Yaesu and it did very little!
That's quite impressive DSP performance. I was hoping you were going to ultra-dazzle me and reveal it also might do digital decoding (P25/DMR, etc...) but I suspect that could be possible in later FW/SW updates...
If it did, I'd be buying one right this moment.
I want DMR and recording
Thats brilliant. Got a good deal on one ! ❤
Well, you sold me...I just ordered one. Not cheap, but they look and sound like a quality product...!!! 😊
Bought one from AliExpress and can confirm “insanely good”. It came with 2.40 firmware installed. Telescopic antenna reception very good indoors and better outdoors…even better with long wire attacked with alligator clip. Preamp and notch filters excellent. Downsides: poor tuning knobs, manual, and no info re memory saving. Altogether light years above competition.
Great video. Is the bandwidth adjustment for each mode a continuously variable adjustment or are they fixed settings? Thanks.
if only the aor expensive hand held scanner had that sdr display nice one sir
I have a Malahit V3 and it is my best receiver since I live in a place with very high levels of noise. Its NB and NR are the best compared to all my best radios. Some come very close such as the Icom IC-R71A (NR) and Yaesu FTdx-3000 (NB).
Good Stuff!! Amazing little gadget! 🔥🔥🔥🔥🔥
Thanks for your review. Would you recommend an SMA Terminator on the unused Antenna port?
I bought one of these. The build quality is absolutely beautiful, but the reception just doesn’t seem nearly as sensitive as on the original Russian Malahit DSP2. When using the Hi-Z setting on this 2023 version, I can barely hear anythin at all. On the 50-Ohm setting with the telescopic antenna, it’s better, but still doesn’t pick up as much as the original DSP2. Listening on 40 meters today, the Russian DSP2 picked up tons of signals, but the 2023 clone only got a few of the strongest ones. Maybe I got a dud or something?
Awesome. Almost unimaginable a few years ago. Good review, thanks.
I reached the conclusion that the only good portable self-contained SDR SW receiver for less than a grand was a transceiver in terms of being able to quickly tune and get to where you want to listen. I have an older Malahit which is kind of usable, apart from the gummy tuning knob that goes backwards almost as much as it goes in the intended direction, but I can’t see the screen outdoors, even when it’s cloudy. This model might change my mind.
yes i have the same ...and your spot on with that lol
@@davidlangford5383is it chinaman fake copy ? or the real Russian one ?
Yeah. In fact the only portable receiver I use these days *isn't* less than a grand: it's a KX3. But this is quite good.
Wow
My next favorite radio!
Good choice!
I've now had the radio a couple months and the only thing I don't like about it is it seems easily overloaded by local stations that are strong. I seem to pick up a good bit of spurious signals and harmonics too. Overall happy with it though.
Sounds very good. I've ordered it a few minutes ago. 🙂
Where did you buy it?
@@Nn-xc4hc I have bought a DSP1 on Ebay. It's a bit cheaper and has a few less functions, but this is not really bad. I'm very satisfied with it. It has the same housing. but in a different colour (dark blue).
Very nice as some have said if it had an Icom or Yaesu badge it would sell like hot cakes, very impressive
Wow I Like This Radio Thanks For The Video!!!!
Seems like an excellent receiver. I was just curious about the bandwidths offered for SSB and CW. Airband sounds great! The NR is really superior compared to other receivers.
I can get 10 kc wide on USB for some of the pirates like MRI and Wolverine that are very wide with my Rusky DSP2, there are 3 presets, narrow , medium and wide but you can tailor each one to your own preference, same firmware so this clone should do the same. NR is insanely good, no loss of high audio frequencies
Hopefully, people will develop firmware for it as they have done for the Quan Sheng HTs.
With respect to the versions sold ~1yr ago It seems they added some bells and whistles and they almost doubled the price!
Similar display, same bandwidth192KHz and so on. Cool
Very tempting.
On Ch38 the Italian guy always comes in strong when mother nature in our favour for the UK roughly 10:00 utc but the guys in Scotland, Ireland, Wales, always talk straight over lol 😂 It’s coming strong now I’ve got my 2 element quad faced your direction. Hopefully I can hear you 🇦🇺👍
Just ordered mine
I was wondering if these existed - portable SDR is awesome
can you get an external ariel to fit this if so what do i need as iam a nofice many thanks
Do you need an external antenna to use this receiver? I’m new totally new to this hobby, so any advice would be helpful. Thank you
I have one question for you, what is the widest it can receive and display at one time? Is it anything like the RSP1a's 10MHz or is it limited like the inexpensive RTL-SDR type of dongles?
Anyway this reciever is chinese clons branch. Russian original reciever now has DSP3 version.
The only fault I would point out is the inability to connect a PC to manage memories or stored frequencies. Otherwise, the DSP2 looks really good and I would buy it for portability or trips, but I don't know where I would store the mentioned frequencies, which I would then like to tune again from my home workplace. Thx for nice rewiev.
Why don't you use the telescope input HI-Z and turn on the preamp?
Really excellent!
Love this and would buy it in an instant but I want my next all mode listening device to have onboard recording. Please let me know if you come across anything with these features that will also take an SD card and can record with a touch of a button.
Just got one. Wow. Incredibly good. Only niggle is the encoder which has to be spun sometimes. Other than that, absolutely brilliant.
Just ordered one .Regarding the static on 40mtrs I have this interference here,any idea what it is
Good video looks nice how much are they to buy just asking can you pick up air band on it just asking where do you get these radio from
Very interesting radio friend.
Got lot stations around of world.
Blessings
KD6TXB nice radio thanks for the review
youre welcome
Could I connect this to a PC via the USB-C port to use as a traditional USB RTL-SDR and/or of the likes to use something like SDR#?
The audio and sensitivity are amazing especially on that antenna. What would be really good is if it had a second mode where it could operate as a traditional VHF/UHF scanner at high scan speed.
I suspect you could use it with a PC and SDR sharp ?
@@doriancreber7139 Yes, you could do that.
As always...great review and YT production. You've got real style. Question for you: Can the Malahit DSP2 be used while charging (or while connected to a battery bank? Thanks!
Thanks! Yep, you can use it while charging. Well, on mine I can. Cheers
Thanks for the super quick reply! Good to know. I think I'll go ahead and order one @@TechMindsOfficial
The interesting thing from this clip was the comment the person made on the airwaves @05:56 the decommissioning of 3G mobile phone signal. As a Blackberry curve user I will lose my internet since only 4/5G will be available. I believe that they will fall back to 2G for only voice and text. So that was a very interesting catch on the airwaves.
Can this unit scan? Can it record frequencies (either built in or to a separate recorder via headphone jack)? Is there any video output (for displaying on a larger monitor when at home)?
Nice device. Can this see TDMA/CDMA? Not demod. See on a spectrum analyzer?
Thats one right nifty receiver. Can you show some time what its like on CW esp its filtering.

Hi, is there a massive difference between the DSP 1. Same design.
Your description says that items shown in your videos are also available through your Amazon storefront. But this one is not offered. Please update by adding it to your listing. Thanks
One of your AE links has it at £228 inc vat and shipping. Is that one also fully licenced?
how high did you have the audio out of the unit while listening?
This looks pretty decent
Im im the market for a radio with a waterfall display. I only listen as im not licenced, so this could save a decent amount of money until i get the licence. I enjoy the ft817 but id like a waterfall.
Get an SDRPlay RSPdx and invest in a good all band antenna and lmr400 cable to converter with ground and lightening protection. It does everything and is the core of any station for receiving. Chinesium radios are never worth 300 bucks, EVER! They hate us and use junk to build gear.
@super66craig could i decode weather satellites with it ? My ft817 doesnt work for them and barely gets a decodable image. Not high enough resolution ive been told.
I am very intersted in this, I have 1 question though. How hard is it to change the battery. Sooner or later the rechargeable battery is going to die, and if I am dropping over 300 bucks on a radio, I want to make sure it doesnt become a paper wieght when the battery dies
Thanks for the video, very informative. I want one…
Glad it was helpful!
Have you done a video on the best antenna for this product?
Nice Video Nice Receiver reasonable price
I was impressed by this tiny Portable receiver.What about its batteries?Is it available and what is it's price?
I noticed this video was from about 4 months ago and that time have you had any problems with this radio?
Can i subject-buy and easy-job, this is changeable from walkie-talkie to radio(entertainment and news or sales)?
Would love to see you review this radios performance on the Medium Wave band.
If you still have this receiver, can you make the same test you made with the RSP2pro trying to listen to ultrasonics bats' sound. Regards.
Why the gap between 381 and 403 MHz? Is it some forbidden/reserved band in Russia? Is it possible to... overcome... the problem via a fw update?
Impressive
What is the difference between the Malachite SDR1 and SDR2 model ?
Is it just the SDR software version?
SINCERELY
does anyone know wha the difference is between DSP1 and DSP2? Is that a hardware change or just software?
Looks and sounds absolutely awesome, but as someone who runs a contest station I know that it's not all that hard to flip the dial and find stations that are loud and sound fantastic, especially when the Solar Cycle is as good as it is now. And yes there are lots of JA stations that have stacked Mono Banders that can throw a 59+ signal on the higher bands in the Morning or near sunset all the way to the East Coast of the USA.
What I would have liked to have seen is an A/B comparison of a weak station on the DSP2 versus any of the normal ham radio transceivers. I have used lots of different radios so that could provide a pretty good reference point as to how well this thing is really receiving.
BTW if I sound a bit wary it's because I saw your video and was really excited, up until the point when I read the reviews on Amazon for the Previous version. Now I need some real comparative proof of how it compares to something like my Icom 7610.
Not an unfair request considering this cost half the price of a full blown transceiver like the Icom 7300.
Note, I am not asking you to do it, but the company needs to get someone to do it.
Can you adjust the tuning step(s)? The display seems to show ".000" most of the time. (Similar question for bandwidth, especially for the 30 MHz and below frequencies.)
Tuning steps are adjustable, the steps are different depending on the mode you are in. There are 3 presets for bandwidth and you can adjust the width for each setting
@@dave10524 - Thank you most kindly.
Nice, looks like a great tool to locate noise sources. Is 192 kHz he maximum band scope span?
DSP3 should be released soon
The receiver seems to be based on a 96 kHz 'audio' chip as the digitizing element or circuit, so, yes, that is the maximum.
This version finally looks practical enough to make me order one.
Its performence looks really good and the buildquality and user interface looks very good.
This has been asked before but does somebody know what the difference between the two Aliexpress offers is?
Only one version ships to my place anyway but still, 100$ difference should have some reason, right?
one is probably real and the other is probably a paperweight.
@@innercityprepper
I see where you a coming from but lets hope you are wrong, since only the cheaper one would ship to my place.
I will report back once I received it.
If anyone is wondering, I had to buy the cheaper one since the other one wouldn't ship to me.
My order got shipped then about a week later it just said "shipment cancelled".
After contacting the seller he promised me to resend it.
After another week I just got the money back without any further explanation.
Looks like no radio for me. :(
I just got mine, and I'm really impressed with it. One minor niggle is that the FM station RDS is not working, even with strong stations and all the settings carefully checked. Have you had this problem? A few letters came though just for a second but nothing since.
I get RDS on mine but only on very strong FM signals. And try waiting a minute or two for the words/info to show up. My car radio in my Honda Civic get RDS a bit better than this does.
Please can you tell us how the encoders are
Are they notched, are they optical, does it skip values?
In short, are they of good quality or medium
THANKS
I need some question about the encoders mechanicaly or opticaly. Thanks vy 73
A little bit pricy, but really good performance.
Dear Santa, I've been very good this year....
The website, Aliexpress says it cannot be shipped to my address?
Looks like they cannot ship to the USA.
