Latest V2.4 Malachite DSP2 SDR Radio Receiver, GOOZEEZOO Shortwave Radio Receiver 10kHz-380MHz & 404MHz-2GHz AM SSB DSB CW NFM WFM Air FT8,RTTY Decoder Function Noise Reduction with 5000mAh Battery

If you've never had a Software Defined Radio (SDR) before, get ready for some fun. For the price point this thing is a riot to use, you won't be disappointed. Keep in mind it's not some flimsy little toy, this is a very sophisticated piece of equipment and may not be suitable for some due to all the advanced features and menu-driven interface.I wouldn't recommend this radio for anyone much under the age of 14 (unless they're another Elon Musk!). Any younger than that, they'll just get frustrated and break the thing. Ditto for some senior citizens who may get frustrated with modern technical stuff (except Ham operators, they can master anything regardless of age!). I'm 72, consider myself tech-savvy, but had to crack the manual on a number of features that were total mysteries to me.I'll tell you right now, after spending just one hour with this radio, you'll wanna throw out those old C. Crane & Tecsun models (both excellent choices in their day). If you're not sure, see if you can find a pdf file of the user manual on the mfgrs. web site; if available, go through it and see if this is really what you want. Some of you may not wanna mess with touch-screen menu systems and all the strange options totally unheard of in non-SDR radios, it can be confusing, maybe frustrating.I purchased an older model of this radio some time ago and liked it. It was kinda dinky with substandard audio due to the dinky speaker. Austere packaging but the receiver was out standing. Then I saw THIS thing and knew I really "needed" it! One can never have too many SDR's! The price is considerably higher now, but what you get is well worth the extra $$$.After picking up the package at the post office, I couldn't wait to get home so I unboxed it right there in the car. Plugged in the telescopic antenna, turned in on and tuned to the 17-meter Ham band. Just with that dinky antenna I immediately saw four signal spikes pop up on the waterfall display, picked one signal and heard this guy from Prince Edward Island, Canada running an ICOM-7300 at 100 wats like he was in the car with me - excellent audio quality.This radio is built solid with an aluminum case. Two knobs on top for volume & tuning, great for old-school dial-doodlers like me. Learning how to use the touch screen & menu selection takes some practice & patience, but you'll get the hang of it, Smartphone users will have no problem.What impressed me was all the stuff that comes with this model (as opposed to the older one): nice hardshell transport case, wrist strap, telescopic antenna, pointer device for touch screen, stick-on foot pads, decent manual, and USB cable. There's also a stick-on gizmo that goes on the back of the radio & folds out to form a prop.For first-time users: though the radio works well enough with the telescopic antenna, it works best when connected to an external antenna. The manual provides a fair amount of detail on what kinds of antennas are appropriate for various bands. But keep in mind there are TWO antenna connections: high-impedance (high-Z) and low impedance 50-ohm, you have to specify which to use. That is done by selecting the HARD menu option on the bottom tool bar display; this will take you to options for setting various features of the radio. Near the top, you'll see a box indicating which antenna port is active, push it to switch to the other port. When in doubt, there's indicator light next to the ports to tell which one is active. Once again, the manual explains all this stuff. I only mention this as it's something that might trip up first-time users.The audio quality is awesome. The Digital Noise Reduction (DNR) feature wipes out virtually all background static, there's also a noise blanker to take out pulse-like noises. These are pretty standard features on all high-end SDR radios these days, especially Ham receivers. The noise reduction on this radio is as good as my Yaesu FT-710 ham rig, actually a tad better.This radio is perfect for Ham operators who want to monitor but can't have their regular rigs with them, even using just a basic telescopic whip. For everyone else: you'll need to sit down with this radio and LEARN how to use it, not that difficult. READ THE MANUAL FIRST!!! Seriously, this will save you tons of frustration. Start out with basic operating features first, learn those before fiddling with advance functions. It will take some time but well worth it. Oh, for those with big fumble-fingers like me, that little pointer thingy they give you works great for pressing those tiny little boxes on the touch screen.This radio is going to seriously challenge C. Crane and Tecsun. You're going to go SDR, or you're going to go out of business.Hope this review was helpful. I didn't go into ALL of the esoteric (though interesting) details, just wanted to let you know I thought this is a well-designed well packaged awesome piece of radio technology for a very reasonable price. Great value for your bucks.

Purchased based on other reviews and the quality. I’m new to the hobby and this SDR Receiver so I’m still learning… so far so good. So far I’ve been able to pick up local chatter with just the included telescopic antenna… which I will be upgrading soon. The fit and finish, as well as the sound of this receiver is as advertised.. Awesome! The visual display screen, even though I feel is a bit cramped is nice and colorful with options for personalization. Can’t wait to learn more get the most out of my new receiver.

High quality . Received all stated frequencies. Very prone to slight overload and noisy display .Sturdy construction. Suggested video to better understand how to program and use of various tools. Really nice radio and compact.

Best HF radio

Being a clone of the Malachite SDR, this Goozeezoo example is about as good as any other implementation and the software/firmware available for it. In that regard, this version is really no different than any other I've tested. If you have used an SDR radio in the past including another Malachite clone or an RTL-SDR Blog dongle type product and the software that run them, then this will be no different.This one from Goozeezoo is a decent implementation and feels well built with the all-metal case and the nicely fitting exterior hardware. The radio is nice and solid. Would benefit from some integral feet or a fold out stand since laying it flat on the table muffles the dual speakers on the back unless you raise the upper edge a bit on a pad of paper.Where this one could use some work is pretty much where every other similar radio can and that's the touchscreen and the rotary knobs. They all function to be sure but they are intermittent and slow to respond. The screen is small compared to a smartphone so you would benefit from using a stylus (rubber tipped) rather than your finger and you do need to be patient with your touches as they don't always register immediately.The rotary knobs are OK but they do not register every "click" even when rotating them slowly. The knob has that soft click to it but the frequency or volume levels sometimes don't change even when rotating slowly and deliberately which is frustrating. Sometimes you scroll forward but the result is a scrolling backwards or a large skip instead. I don't know if this is the knob hardware at fault or the circuitry and software being slow to register the pulses from the knobs.Also, my particular unit does not always register the pressing IN of the knobs, especially the frequency knob which is used to change the frequency step so you can tune faster or slower. I can push it in several times with no reaction from the radio before it finally allows me to change the step value. Sometimes a reboot helps. Sometimes it just doesn't want to register a push at all. It's just intermittent and a bit frustrating.Lastly, the battery in this unit appears to get fully charged (LED is green after letting it sit for several hours) but the charge indicator on the screen goes yellow/red quite quickly after disconnecting the USB charge cable. Not sure if that's just a firmware glitch not registering the fully charged voltage level which a firmware update could remedy. When connected to the charger, it shows 4.6V I think but, when disconnected, it shows 3.5V right away and does stay there a good while but the battery icon is yellow/red earlier than I would expect.So it's a good product in line with all the other clones out there and I have similar experience with other makes so none of the above mean the radio is bad. It's just not leaps and bounds better than any other. It's at a reasonable price so it's worth a purchase. Just could use some better hardware, software or a faster processor.

Yes there are many setting to consider so take some time to get accounted and make sure you have a good antenna. The sound quality is outstanding, the sensitivity is unbelievable, the visual display is detailed, high quality and keeps your interest for hours. I set up some aircraft frequencies to scan and the quality of voice, frequency sensitivity and ease of each aircraft frequency scan selection is impressive. This is my first SDR so its a new view of radio frequencies for me and the frequency coverage is way beyond any of my other SW radios. My primary use is for VHS emergency frequencies, Aircraft monitoring, GMRS monitoring, FM listening and occasional Ham monitoring. The manual is not detailed so I found just trying each setting and logically experimenting with each menu got me to a workable knowledge of the SDR. This SDR has it all, well worth the dollars spent.
