NESDR Mini (TV28T v2) USB RTL-SDR, DVB-T & ADS-B Receiver Set with Antenna. RTL2832U & R820T Tuner. Low-Cost Software Defined Radio Compatible with Most SDR Software Packages

Works brilliantly with home assistant - allowed me to pick up my 433mhz weather station using MQTT and feed the sensors directly into my dashboard. No more pesky seperate screen required! The device is fairly compact and just slots into your USB A port, the antena cable is quite short, i personally would have prefered it to be longer so that i could distance it away from the electronics, however you are very limited in distance with the included antenna. The device does get quite warm when left on 24/7 but nothing that would overly concerned me. Home assistant configuration was super easy with the RTL-HAOS add - i did find i needed to sort out the noise ratio with some YAML as the pre set formula didn't work well for me. Apart from that this really is a plug and play device. I am happy with it and would recommend it to others.

These are great devices - I’ve bought 5 so far and use them with a Raspberry Pi running FR24 feeder software. Easy to set up and provides a good range.

I've been using this for a little while, getting into what Software Defined Radio is, and what you can do with it, and looking back this is probably one of the best choices I could have made. The Interface and Tuner IC's on this USB, the Realtek RTL2832U interface IC & R820T, are the best out there for SDR at the time of writing and give an incredible range meaning that reliable reception is possible of radio waves from 25MHz to over 1750Mhz. That makes AM, FM, DAB Digital Radio, ADS-B (Aircraft) Transponder Reception and, allegedly, Digital TV reception is possible with one USB device. I say allegedly for TV reception because I haven't tried to make it work. Getting it to work is a breeze and there's plenty of open source software already written for Linux, MacOS and Windows that makes finding drivers that work much easier than I was expecting - that's down to the Realtek RTL2832U chipset - just type rtl-sdr into you Search Engine and you'll be spoilt for choice. The NooElec is a nice design that slots firmly into place - a plus if you're mobile - and the design allows for ample ventilation of the IC's inside. Other than that there's not much else to say about the USB stick enclosure other than it's on the large size so you might want to use a good quality USB extension cable if the space between the USB2 or USB3 slots on your machine are rather close (and you'll definitely need an adapter if your machine only has USB Type C but you probably knew that). It also comes with a handy 5dB aerial which itself has a handy magnetic base that'll help you get started. Don't expect miracles from this aerial though - depending on your project you'll most likely want to use or build one that's tuned to the frequency bands that you're interested in. That said I was surprised at how well it performed across all the spectrum which is testament to the quality of the R820T Tuner circuitry. When coupled with a purpose built aerial is when you see how remarkable this piece of kit is - it's range for picking up radio signals is truly remarkable.

Got this to track planes using ADB-S with Flight radar 24 and my raspberry pi Model 3B. I've now had it online for four weeks continually and it has worked flawlessly. This was the best price I could find any compatible dongle and as a bonus it came with the antenna. The antenna is tiny and for tracking planes it works but isn't the best. I changed it for a ADB-S antenna from the Pi Hut and that doubled my range. Overall very pleased and great value for money.

I have mixed feelings about this. I wanted a simple DVB-T dongle so I could watch TV from my PC and came across this which is basically 2 devices in one, a DVB-T receiver and also an SDR. I hadn't even heard of SDR but I thought it might be interesting to have this as an additional thing to play around with, but the TV receiver was the main reason I bought it. However, getting it to pick up TV signals was an absolute nightmare and I spent 3 days messing around with drivers - the ones shipped with the product don't seem to work, and Windows 10 installs some ancient drivers from 2009 and then informs you that these are the most up-to-date ones available. You need different drivers depending on whether you want to use DVB-T or SDR, and the device came with a "driver switcher" application which you need to be very careful with, it's incredibly easy to accidentally replace your wireless keyboard/mouse driver which will ruin your day if you don't have a wired one around somewhere!) After much frustration I eventually found some 2012 drivers which I managed to get working on one of my Windows 10 PCs (the exact driver version is 64.1.801.2012 and can be found by searching for a file called Treiber2.zip), however, I still can't get this to work on my main Windows 10 desktop and am on the verge of giving up. Regarding the SDR functionality, I got this working quite easily on Windows 10 using the supplied drivers and some freeware, and on my Android phone (Galaxy Note 3) - using an app called SDRTouch I was able to pick up various radio broadcasts, and with an app called Avare ADSB I could pick up aircraft transponders (note that you need to install an app called "Rtl-sdr driver as well, plus you'll need a USB-OTG adapter). On Android everything worked instantly with the single driver with none of the frustration I had with Windows, although there are no Android apps that can pick up TV which is a shame. In a nutshell, if you want a combined DVB-T and SDR device for Windows and Android and don't mind lots of hacking around this is actually quite good, but if you want a pure TV dongle there are probably far simpler options available.

Got this for Flightradar24 "build your own ADS-B receiver" to use with a Raspberry Pi computer. All I can say is that it works. I am only using the supplied indoor telescopic aerial in the loft and it is picking up a wide range of aircraft data for FR24. Tweaking the aerial length affects the quality of reception, but it doesn't go short enough for the quarter wavelength (6.9cm) recommended by Google AI. Apart from that I can't fault it.

The dongle works fine but the aerial that came with it is not like the one advertised and dosent work as well. It also can't be tuned to specific lengths as it's a bad telescopic aerial

I used this together with urh to decide some pretty complex rf modulated digital codes. It works really well and is great value

I've never been all that interested in radio, or spending any money on it, but when I saw a video describing these $20 RealTek chipset based dongles and how they could be used for SDR and radio spectrograph type applications, I was like "For $20? Count me in!" Like most people I'm using SDR# and not any of the vendor's drivers. The thing that took me a little while to figure out was that the USB drivers for this thing have to be installed manually. (There's absolutely no "plug and play" support for this thing at all, because the driver used by SDR# is a very generic low-level USB driver that is only designed to allow applications to essentially talk directly to just about any USB device supporting some serial protocol.) The easiest way to get this working is to download sdr-install.zip from the SDR# web site, extract it, and run the install script that will download everything you need including zadig (the generic USB driver installer), the RTL chipset plugin for SDR#, and SDR# itself. Before running SDR# you need to run zadig.exe and use it to install the driver. This requires that you select "show all devices" from the Options menu, select your RTL dongle from the pop-up menu, and tell it to install/reinstall the WinUSB driver for that device. Be careful to select your RTL dongle before hitting install or you may accidentally install this over your mouse driver or some other device. (Like I say, this is a generic driver that installs a really basic software interface for any USB device that supports certain attributes, so there's nothing to stop you from overwriting one of the other drivers on your system if you select the wrong device.) Once the WinUSB driver is installed you can just run SDR#, select the RTL device as the input, and hit play. Tip: I'd recommend turning on the auto gain check box for the tuner ("Tuner AGC") in the configuration panel though, unless you want to mess with the manual RF Gain control. (I was able to do pretty well just using the auto gain, but before I enabled the auto gain every signal I was getting was very weak. So you really need some sort of gain adjustment be it manual or auto.) Without much effort and using only the little included antenna I was able to pick up NOAA weather radio (narrowband FM), a number of commercial FM radio stations (wideband FM), the wideband FM transmission from a Sennheiser RS110 926MHz analog wireless headphone transmitter, and see a bunch of other signals on the spectrograph that I didn't recognize. I was also able to pick up 2 or 3 ADS-B transmissions from commercial airplanes, even though I was sitting in my basement and using only the included antenna, though all of these airplanes were within the line of sight angle provided by the window in the room I was in. So this tuner seems to be good for ADS-B, but obviously you're going to need an unobstructed outdoor antenna of some sort to receive signals from all directions. The remote control that comes with the dongle seems to be totally useless since it appears to be an IR device and I don't see how a computer can even receive a signal from it without a separate IR receiver device. (The NooElec dongle doesn't appear to have an IR receiver on it, but I could be wrong.) In any case it would require either the vendor's DTV software or some other software to make any use of it, and I don't know of anyone who's written anything useful that it can be used with. At some point I'll probably buy a MCX to some sort of coax adapter and wire up a proper antenna for it outside, but for now I'm just messing with the cheapo little included antenna. It seems to work better than I expected. Anyway, this is the most interesting $20 gadget that I've bought in a long time. I suspect that one day it will come in handy for helping to locate and rectify sources of radio interference.

Less clear sound and signal quality than I expected compared to a Boofwang K-5Plus, I tried it on VHF and UHF but no real clarity from any of the local repeaters
