Nooelec RTL-SDR v5 Bundle - NESDR SMArt HF/VHF/UHF (100kHz-1.75GHz) Software Defined Radio. Premium RTLSDR w/ 0.5PPM TCXO, SMA Input, Aluminum Enclosure & 3 Antennas. RTL2832U & R820T2-Based Radio

The NESDR SMArt v5 Bundle comes with 3 aerials, short one is for UHF ( suitable for 500MHz - 1900MHz), the mid size for 70cm (400MHz - 470MHz) and telescopic aerial can be adjusted to the desired frequency. If you know the frequency range you want to tune in, you can achieve very good results by using telescopic aearial and any online Vertical Antenna Calculator. I have used this SDR mainly for Weather Baloon Radiosonde Tracking with Raspberry Pi4 2GB and software from SQ6KXY. Over the weeks I have tested it with Mac and many different flavours of Linux on a X86_32, X86_64 and ARM 32bit and 64bit (Raspberry Pi) platforms. Each and every time SDR was recognised without any issues. My unit has been in 24/7 operation for for several weeks now, while it gets fairly worm, it works reliably. It can receive clear signal from radiosonde 200km away at 30,000m altitude with 1.5m diapole antenna. The digital signal is clear and received messages do not contain errors. I have tested it on most Amateur Radio bands too, and ADS-B for flight tracking all with great results. I can highly recommend NESDR SMArt v5 Bundle to any radio enthusiast. I will be ordering more of those SDR's for my RX project to be able to cover more frequency ranges at the same time. All the best

Great little kit, performs well. I've noticed a few software glitches, e.g. if you sit on a specific frequency for too long you'll have to restart the process again to retune further. Gets quite hot but hasn't failed so far. The magnet isn't stuck onto the stand very well so I have to fully extend the antenna to weigh it down. Probably not a great first impression to new users, the drivers have to be manually installed using external software, and there's no help provided directly by NESDR as far as I'm aware (this may be inaccurate). Otherwise brilliant, a great product considering the price.

Good product

UPDATE: After removing the plastic case and putting the AC on 18'c in the office.... it works well. Bought one of these in December 2016 mainly to use as a Spectrum Analyser and band monitor to check for illegal radio users interfering with my licensed DRM repeater. Very impressed with its performance. A little tricky to get working under Windows 10 x64 and to persuade SDR# to recognise it but once working it is great. I have a proper wideband scanning aerial on my radio tower which helps but when I tried this with the supplied magmount and telescopic aerial on a biscuit tin at my house I was very surprised how sensitive it was. Actually not selective at all and suffers overload from strong nearby transmissions. This is where one needs to be an experimenter - I found the strong signal and made a simple notch filter to compensate. Unfortunately the SDR met an untimely end, it fell out of my rucksack, unbeknown to me and was accidentally run over by a 6.5 ton armoured vehicle the USB plug is bent but probably it could be repaired. Easiest to just buy another SDR, which I did...... now waiting for delivery. When you order these SDR, the seller emails you via Amazon with the links for the software and this works "out of the box" although not as good as SDR# and the multitude of plugins it easliy shows the capability of the device.

Nooelec RTL-SDR v5 Bundle. Great bit of kit, very easy to set up. Works well with cubic-sdr. I would recommend a better antenna if you want to pick up more channels.

The item itself works well or certainly as expected with a reasonable learning curve with the software side, so no complaints on the item itself. However, I paid extra for the option with the 3 antenna's for which were much smaller than expected when they arrived. In fact at first I thought I had a faulty item as I was picking up nothing except some rather poor sounding FM broadcast radio stations. Tweaking or repositioning the antenna helps with radio stations but even when I got to grips with the software it soon became obvious and confirmed via research and third party people that the 3 desktop mini antennas are at best of very limited use and next to unless in a lot of locations. Of cause I'm not expecting to pick up transmissions from 50-200 miles + away eith a desktop antenna, but im struggling to pick up much at all outside of broadcast radio stations and it would certainly have been reasonable to have expected to pick-up something even with these small antennas in the suburbs of a major city with loads of retail locations within 2 miles of my location. This item description should be made clear of the reception limitations of the included antenna's. Had I realised the 3 antenna's were just to limiting I'd not gave took that option and instead put the extra money to a decent desktop antenna instead.

simple to use and implement with linux. Good performance for the price.

***EDITED*** I was impressed but short lived !!! From my technical mind this thing needs a heat sink and fan, after a few hours use the usb extension got too warm then started to have random disconnects, assuming it was just the lead that was faulty I taped the lead to my work bench so it couldnt move, I also strapped two old motherboard heat sinks either side of nooelec using thermal pads. This helped cool the device somewhat but fear the dodgy lead/heat has damaged something internally. Now it just keeps crashing and disconnecting even without the extension. A real PITA because i've just ordered a better antenna to go with it :( ***EDIT*** After further reading and testing I can confirm the usb extension lead was faulty. The nooelec will certainly benefit from a usb hub too (It remains connected in windows device manager if you get a crash) the added heatsinks and thermal pads i added certainly help cool the device for my needs and should be an after thought for long term use. It's been running solidly now 24/7 for the past few days but will drop one star for the dodgy cheaply made usb extension. A cool purchase for venturing into the world of SDR

Tenía la idea que los materiales serían de una calidad más baja, pero se percibe las ganas de hacer un producto de buena calidad con n costo razonable. Buenos acabados y los conectores traen protectores de plástico. Todo funciona muy bien, aunque llevo solo 1 día probándolo

Ürün malzeme kalitesi güzel fakat dışının metal yapılmış olması fazla ısınıyor gibi hissettiriyor.

Funciona a las mil maravillas. Incluso he probado a conectarlo a una tablet android y usarlo en movil. Perfecto. Se calienta mucho, es recomendable ponerle algún disipador y así funciona más estable.

全面アルミ製の外装で放熱性が良い。安定度も今のところ全く問題が出ない。USB端子の作りがしっかりしている。 アマチュアバンドをワッチしてみると、SSBの受信は自分の無線機よりクリアに聞こえた（ソフトとの兼ね合いもあるかもしれないが）。FMは当然まったく快適でクリア。 付属のアンテナを使用してADS-B受信を試すと、高い高度で飛んでいる航空機であれば半径250ｋｍ以上でも受信できた。 その他、ラジオ放送、いろいろな無線などとても満足な受信が出来ました。 『その後』 夏になってきたら、発熱の問題が出てきた。変調がおかしくなったり、ソフトのアナライザー画面がいつもと様子がおかしいと思い、本体を触ると凄い熱さ。 ３０分も受信していると、素手で触れないほどではないが相当な熱さになる。 自作で効果の高いヒートシンクを付けるなど対策必要。

I bought this SDR as a replacement for my malfunctioning FlightAware ADS-B receiver. Although it can do a LOT more than I currently use it for (Flightradar24) Reception and stability is great!
