Pocket ALL BAND/ALL MODE SDR receiver (Malachite clone) 

Thanks for this Paul, I like the way you give the good and the bad points. A very fair and informative review.

That is very impressive. I've been eyeing one of these and think you just sold me on one with the better dials. Thank you very much for your time making this video.

Radio is coming on so quick, imagine what we'll have in another ten years. DSP is simply amazing.

Amazing how far we've come in the last 10 years !

Wow Great ! And that NR is impressive

Nice video, great little RX and nice mods. NR is impressive.

I simply can't believe how well the noise reduction works!

Informative video. I find that often, rotary encoder implementations lack suitable debouncing. Capacitors help, but Schmidt triggers are the ultimate solution.

That thing is tiny! It's great. Love these tiny/compact SDR devices. :)

Lovely piece of equipment.

PS, there has been a lot of comments on how good your review of this clone sdr is. I have the exact unit. Thank You so much for such a good review.

Wow! That’s the best Noise Reduction I have ever seen!

Wow That’s Awesome! A small but great little receiver.

这个产品最近卖的非常热，我的朋友刚刚拿到。很nice

Good video and review. I'm going to order one.

Enjoyed the video, Paul...nicely done review of this receiver...thank you and 73! de WX0V

Nice review! Thank you for sharing.

Very useful video full of helpful information. Thanks!

I would love to own something like this. I'd carry it everywhere with me. One thing that is missing is the ability to record broadcasts to audio but I have a good digital recorder I can hook to this.

WOW! The NR on this thing is simply 🤯 !..

Thanks for your very good report, I have ordered one with upgaded firmware from Banggood... Looks to be very nice....

Wow! Many thanksfor your detailed description/analysis! I purchased one on Ebay from a U.S. seller for about $100.00. Looking forward to using this receiver! 73, Bill W3MSH

This thing is sooo cool i must have one

Very nice review and nice work on the inside of the case. 73

A note on those encoders jumping around. It happens because dislodged particles inside form short circuits. Open them, and clean them with a brush dipped in alcohol, or pressurised air. New encoders will develop the same problem in time.

There will be people who do not agree with you, but you call it how you see it and I respect that! This receiver does need part upgrades you mentioned. It could use solder upgrades too. Lead free, at present is a big disappointment. Perhaps this will change, but for the present time, it remains disappointing. If you disagree, it’s your choice and I respect that, but I have seen the problems lead free brings and they don’t outweigh the leaded advantage. Thanks for sharing this video. I enjoyed it immensely. Stay safe mates!😊👍🏻😷

Thank you for taking the time with explaining this device - #PyrateRulz

Your channel is very informative and useful, thank you Paul 🙏.

Really nice coverage of this sweet little receiver Paul! That Noise Reduction is AMAZING! Great job of modifying it as well. Did the shielding you added make a noticeable difference Paul? 73, KF6IF

Hi dr OM, nice Video , good Job ! What would you are using for new encoders ( Typ, factory, perhaps a buy-link) tks 73 fm Dessau, de DF7MR , Mike

Thank you for your good work. I'm afraid I have to agree with the other reviewers who say that these are, at best, and unfinished product. I think it's fair to say that any product that needs the terminals resoldered and shields added isn't quite done yet.

Thank you for your videos! I have a USB version, that was only $30.00 US and a second one that was little less than that. Both came with software, the $30 came with a commercial software.... Both came with several antennas. The reason I purchased it is (I hope) to detect small wireless buttons that control my lights in my basement office and the rest of the house. How would I detect the exact frequency? I have 2 lights on main floor and sometimes the bedroom light turns on my outside lights, but it doesn't do it every single time. I like to detect what frequency it is and see if it can be tweaked or adjusted, so the different remotes aren't on the exact same frequency. I like to play with electronics, like Arduino, Raspberry PI, NE555.... and I do have couple scopes and a generator.... soldering stuff, so I can desolder or replace parts if needed. But I'm not as good with the great equipment I have here, so I need baby steps instructions. Also, can the unit you are showing here give me an opportunity to use it as inexpensive electronics Analyzer? I'm restarting my hobby after 50+ years working with computers and photography, and now it is harder to learn. But I have time and the drive to learn, so I have nothing to lose. I also fix stuff and put it on my RU-vid. My personal website (very simple) is tonysfun.com/ and there is a button that takes you to my videos. I also ask questions on my videos - like when I was fixing Tektronix scope that I purchased used and is now working, thanks to couple viewers that suggested a stuck switch. Thanks god it was that simple. If anyone else can point me the right direction, please don't hesitate to contact me. Thank you and have a great 2021 year!

Thank You much for the previous reply. Somewhere I saw a video of some internal shielding work and a resistor not being soldered. Was that one of your videos? I cant find it.

Great bit of kit I’m interested I have a MLA-30+ receiving antenna cheap good performer for broadcast DX

Makes me worried that the radios being sold do not have the necessary shields. You certainly can spot the design flaws. Another good video of your cool toys.

VERY impressive litttle receiver!! - and now i will cry for a while....😆😆

Hi Paul, very nice

so cool. devices like these were science fiction 20 years ago

Well I think I’ll hold off until a ‘finished’ product is offered and tested. You save me some money. Thanks!

Lots of useful info, cheers.

Excellent review, thanks for sharing. Would be interesting to see how it performs on mediumwave

I love your videos and really enjoy when you go outdoors and test your antennas. I bought one of these 2Ghz versions. It arrived and powers up nicely but I get no reception with the included antenna or any of my HAM antennas. In fact, there is no difference between no antenna, included antenna and my own antennas. I'm wondering if the SMA connector came unsoldered inside but I'm afraid I may screw up my return prospects if I open the case. Any thoughts?

hi Paul..great and interresting videos.. where did you find your model, and the price...the same as original malachite ?? 73 s from pascal

Nice presentation.

erg leuk Apparaatje ook mooi Klein

Paul, did the screening make a lot of difference? Mine has a lot of birdies in the HF bands. Is the mod worth doing? Great vids, by the way!

Excellent review. Crisp video. I'm also interested in the loop antenna. Could you tell more about that?

Great video when I get it csn I start to use it or do I need to upgrade the software first look forward to hearing from you Paul in Kent

Can it be attached to a computer and have the display on the computer screen along with controlling all its features from the computer similar to a SDRplay. How does it compare to other SDR receivers like the SDRplay and more?

Thank you for the review... I wonder if you know if the $50 Russian Firmware upgrade has the same NR performance?

Great video, and Kudos to you for not having scraggly a$$ fingernails , like so many videos now a days

Paul.. thanks for the video. i still enjoy your magloop antenna ;) BTW two questions. 1. a pointer to where I can buy this unit 2. any way to use this was a panadapter for my HF transceiver that has 9MH IF signal output & cat control. thanks a lot.

I ordered the one with large knobs from Bangagood , full version, wait ing to see how it compares to my Aferdri stand alone model

Ordered mine from Banggood over a month ago, and it finally came back in stock and shipped. Hopefully it doesn't take forever to arrive here to the US.

This is the most complete video so far!

how well does the noise reduction work on weak signals ? it appears to work well on strong signals but i think blanks out weak signals, that defeats the purpose of a noise reduction feature in receiver. that missing shielding on the board is what it should come with from original factory, its a bit like a house without a roof. how does the reception quality compare to an Airspy+ or a SDRPlay RSPdx between 150khz and 30mhz ? those require an extra computer to work but are about same size. i like the build in screen with the waterfall display and recharable battery, works independent from an extra computer. i would like switch to cut of the screen from the battery, that should max the battery time, screen will be the most powerhungry part in all of this device.

Ultra-thin 50KHz-200MHz Malahit SDR Receiver Malachite DSP Software Defined Radio 3.5" Display Battery Inside Nice Sound - Black 400MHz~2GHz 2021-01-26 15:50:19 I am impressed! Fast delivery! Great service! Recommend 👍

Cool device

That knob on the loop needs sheilded, unless that was the lag of NR. Cool little setup. 160m and 75m is more interesting QSO's after worldwide contact rabbits gets old on 40m and 20m. Don't forget less congested 30m 15m, 12m, and good old cb band.

Thanks for this impressive video! Do you have success with changing the faulty encoders or you only resolder them?

Wish the price of these would come down. Being disabled/fixed income is bad enough but then you also have to buy a code to un-lock it fully is just too much. Nice video all the same. Just make's me want one more!

Does the upgrade only give you frequencies higher than 200mhz? I would only use it that way if it works just as good without the upgrade.

Perfect ! Great thanks for this demonstration

Wow What Cool Device...

Super Cool!

I have the exact same unit in this video from Bangood. How do you direct enter the frequency, tapping on the readout wont give me the keyboard. Did your stock firmware include the direct entry screen or did it appear when you paid the 50 for the full update? Also, allot of other function arent there either, freq below the waterfall, mode selection, many others. Thanks and an excellent review.

When you upgraded your radio in the video your new firmware came right up, is this true, or is an activation code needed and what comes up if it has not been activated when you put new firmware in?

Thanks very nice indeed. How much to get it unlock for upper band ?

Great video! Perfect timing for me. I placed an order for one through Banggood after watching this. I received one from Amazon last week, but it has horrible crackles in the audio and intermittent signal issues. I will be returning that one for a refund. Did you have to solder a jumper in order to flash the firmware?

Wow, can it decode apco 25 phase I like my whistler WS1040 handheld scanner? Just curious because I really wanna downsize my ham station but also be able to add reception of our emergency services to it too. Also where can I purchase this unit as well.

Looking at the PCB, it seems the add-on active antenna board will not be possible in this variant

Very nice review. I understand, correct me if I am wrong, that the update is to extend the receive frequency up to 2GHz. How is the performance on the VHF and SHF bands. I an very impressed with the NR is the performance the same after firmware? update?

I love it good Keep uploading videos like this

Nice little receiver. You did not like the rotary encoders in this version. Did you find something to change them out to a better part? There are versions of the Malahite (misspelled) that have two knobs sticking out of the side of the unit. Do you think that they may be better? They do not look as nice. Thanks.

That display is amazing quality for being a Chinese clone!

Awesome! What is the model of the antenna used on this video? Thanks

Hello,i have same radio that you have,but more bigger(there is speakers bigger inside)I also modified it little bit.It has been changed audio codec

Can you directly enter a frequency, or do you need to use the freq knob to tune?

Good...mr..

Wow, best NR i ever heard!!!

Ok I must get one.

Hello Paul, How is the quality of the of the side vfo knob for fine tuning the frequency?

Hey Paul. How much time do you get from 1 charge of the battery ? Tnx fer the video..73

Very interesting variant of the Malahit SDR. I might get this version. Will you let us know when you do the encoder upgrade? As a noob, I’d like to follow along.

I’m probably getting one now. Also, they have HF QRP radios for 130 us dollars. Can you review one?

What is the difference in the software? Is the original software sufficient?

Great video! I noticed you have the same ARM chip I do, it does not have the "Y" which is supposedly needed to program without the used of SD-link but I see yours did work. Am I not seeing the "Y" on another chip? or will mine upgrade through the USB without SDlink also? Thank you

I HAVE AN OUTDOOR ANTENNA COULD YOU TELL ME WHAT CONECTOR I NEED TO FIT THE RADIO CONECTOR ON THE RADIO,THANKS STEVE

Worth mentioning, you can do this sort of stuff on a smartphone too over websdr service. It is a webpage that can do this. Looks like a cool gadget though..

Very interesting, But too much for me to continue to watch, Tried to find out if there is given a receiver sensitivity. Do you know what the 12 db or the 6 db is of this receiver?

Cool now I have to save my pennies lol take care ! 73 de ve3hip from Welland Ontario Canada 🇨🇦

Link to where you got this version please.

Hi Paul, nice review! Banggood has an option with 2GHz for additional 55 euro approx, is that the version which is already activated with the latest original Russian firmware? Seems like it would be a good option to get that if it's all already done. Or do you still need to pay additionally for an activation code and so on with that model too? It looks like a perfect companion for my FT-857d if I installed a SDR-TAP I could let the radio do the switching and it would be like a second receiver and pan adapter. I suppose it doesn't do CAT control does it? That would be the icing on the cake!

A pocket radio that uses a room size antenna. What'll they thing of next?

Im going to use this in my little DIY project.. I have a question. I think the one i bought have the "V processor.. hmm Is that a problem? And also is there a default frequency when you boot it up? hehe and anothe questio.. I want to use another encoder relocated from the board. my idea is to desolder the encoders that are there now and use other ordinary encoders.. But hmm no clue what type of encoders that are in this china clone.. need to know wich pi is wich "clk, dt, sw, gnd and vcc"

Sounds like the encoders are being debounced - perhaps using RC filters. Maybe the firmware could be improved and noise could be effectively removed by deploying a simple finite state machine. I've used this technique with an amtel microprocessor and no RC support circuit.

AWESOME. Can it pick up transmissions over digital? also, can it intercept communications to cell towers? sorry, i dont know much about this subject.

I have a question. Is this radio can decode drm trucked transmission p25 and others?

I like the smaller knobs on the Chinese version not those big ones or just use a bigger radio.

Suuure I'm totally purchasing that Russian software....... 🏴‍☠️
