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

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.

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

Well, this receiver is very nice for starters, especially the ones who never played with SDR based radios. So I've would rate this 5 out of 5 on this one. However, I've ran into issues with drivers, and the software, out of 5 softwares only one worked. Dont get me wrong, thats not a complain because it could be just misconfigured software( since I never got that far, because 1 software works well with -SDR# ). The radio itself is a bit noisy, but it's fixable if you have steady hands and a bit of SMD soldering experience in past. The casing itself looks solid, however, I would strongly suggest you to use SHIELDED USB extension coord, because radio itself is a bit too heavy for USB port, and it may damage your port. The antennas are Okay, possible to catch airplanes and airport with telescopic antenna , and 10 metres above sea floor. In general, considering price/reliability/performance, I've would give a strong 4/5.

This comes with a USB extension lead (with ferrite core) so you don't need to buy this an extra. All you have to do is download and run the software to get it going. To save you what took me a day to sort out go straight to airspy.com/download/ and download SDR#. Next INSTALL RTLSDR, this will put the ZANDIG file in the same directory. Use ZANDIG to load the correct drivers for the dongle. NOW run RTLSDR and you should very quickly be able to load up an FM radio channel and listen to some music. I started off using HDSDR software and got nowhere when it came to listening in to an FM radio channel - probably me - but SDR# was just way quicker and way simpler to use. Enjoy!!!

Much better than the cheep one, works well, this my first try a SDR, read the setup before starting.

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.

SDR Radio for PC tablet and phone. Works better with outside aerial but comes with small magnetic aerial for mobile.

I had a 1m USB extension cable in my package. Had terrible issue with signals, took the cable out and all issues solved!

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

El receptor SDR se nos entrega en una bolsa cie plástico con cierre de presión junto a tres antenas y un cable alargador USB. Tras ponerlo en un PC portatil y usar el sotfware correspondiente, funciona con SDRSharp, SDR++, SDRCube, etc... lo hace sin problemas. Eso si, las antenas que trae valen para mas bien poco o para sintonizar emisoras locales, si quieres sacar el máximo rendimiento a estos dispositivos, has de usar antenas mas "PRO" y lo mas altas posible si vives enviudad y estas que incorporan te serán útiles en zonas elevadas de montaña y despejadas de "muros" que reflejen las ondas o las reboten. Un kit para iniciarse en el mundo de Radio Definida por Software pero si ojo, si ya disponías de uno similar, RTL-SDR, no vas. a notar diferencia alguna y sobre calentarse, a mi no se mesobrecalienta, está todo el tiempo templado, no quema en absoluto. Espero que esta reseña te haya sido útil 👍.

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

Arrivato puntuale, montanto su raspberry 5 e funziona benissimo! Amazon per la consegna sempre una garanzia

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。
