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

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

I'm a novice in the world of ADS-B receivers, and I was excited to try out the NESDR Mini (TV28T v2) USB RTL-SDR, DVB-T & ADS-B Receiver Set with Antenna. As someone new to this technology, I wanted a device that would be easy to use and perform well without breaking the bank. The NESDR Mini has exceeded my expectations. I've been using it with Flightaware, and so far, I'm impressed by its range. With the standard antenna included, I've been able to receive signals from aircraft up to 200-300 km away. Overall, I'm extremely satisfied with the NESDR Mini and its performance as an ADS-B receiver. It's a great starter kit for anyone looking to dip their toes into this technology, and it's been a valuable tool for my learning experience so far. If you're new to ADS-B or just want a reliable and easy-to-use device, I highly recommend the NESDR Mini. Pros: Easy to set up and use Good range with standard antenna Compatible with FlightAware system Affordable price point Cons: None notable at this time.

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.

So far so good. Initially played around with this on win10 using sdr sharp. Worked pretty well on FM but I think the antenna is holding it back. Especially on AM when trying for air traffic. Was also able to tune to TV chanels too, using an otg connector on my android, with one of the many available dvb tuner apps. I'm currently running the flight radar 24 pi image on a Zero 2 W. It's only been running for 24hrs so far, but it's had no issues tracking and feeding the flight information of planes up to 80nm away. With the supplied antenna sat on a bedroom windowsill. Very easy to set up and will probably be getting another one as I've settled on using this only for flight radar now. (1 year on) Been running 24/7 as an FR24 feeder. No issues at all and zero downtime. Perfect for getting that Flightrader business account.

I was originally skeptical about this product, I wasn't sure if it was worth buying because radio reception in my area isn't exactly the best. I purchased the product for a raspberry pi project I had been working on which required something able to tap into specific frequencies. When I first unboxed the product, I tested it on my desktop computer. Every frequency above 120 mHz was inaudible and provided no signal. I quickly realised this was no problem of the manufacturer, nor was it a faulty product, the PSU in my computer seemed to be generating interference above those frequencies. I then moved on to testing it for its intended purpose and what I got out of such a small device was incredible. I was able to pick up radio signals from upwards of 20 miles away depending on where it was mounted and the TV aspect also worked flawlessly too. The reason for the 4 stars instead of 5 is purely down to the heat generated by the item. The little stick gets super super hot after quite a long use which makes it quite difficult to remove without a physical burning sensation. This usually isnt an issue however because it takes about a minute or two of sitting there to cool down again.

Alles OK

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.

ads-bを受信しflightradar24のContributorになりたくて購入。 初号機が故障したので２代目の購入となりました。同封されていたアンテナが短く頼りなかったので、初号機のアンテナをそのまま使用しています。自宅２階の窓際に置いてありますが、問題なくデータを受信しています。今年の夏は気温が暑く熱暴走し初号機が故障しました。熱には注意が必要です。
