Nooelec NESDR Mini 2+ 0.5PPM TCXO RTL-SDR & ADS-B USB Receiver Set w/Antenna, Mount & Female SMA Adapter. RTL2832U & R820T2 Tuner. Low-Cost Software Defined Radio for Windows, Mac OS & Linux

I like it! I use SDR* (this unit in particular with the "HAM IT UP" converter) to spot signals/callers on whatever ham band I'm working at the time - a bit "wimpy" (sensitivity seems to drop off a bit on my module) at the AM radio frequencies and lower - If you want it for VHF and UHF listening it seems perfectly fine (police, fire, weather) I've had some compatibility issues with certain older USB ports - I also have had a bit of trouble getting it to work well with SDR # (again on some older machines and one newer machine) which surprised me a little - BUT since I basically use HDSDR and it worked very well with that, I didn't fight very hard to resolve the SDR # issues on some machines - it is definitely compatible with either SDR program and many others - it works VERY well on both programs on my Lenovo YOGA PRO 2 - it's an eye opening experience for such an inexpensive module to get an insight in to SDR, esp. if you've never been exposed to SDR before *SDR means software defined radio (on edit 2/14/2016) This unit has totally converted me to SDR - I will be buying some kind of SDR FLEX transceiver system as a result of this unit, but I digress - HF. VHF, UHF, different modes, and then there's aircraft tracking as well - there just doesn't seem to be an end to the things I keep discovering it can do. If you're at all interested in radio modes, sw listening, and can't or don't want to invest a lot of money, this is definitely the way to "get your proverbial feet wet" You definitely want an upconverter though if interested in SW listening or HAM RADIO. (I'm using NooElec's V1.3 unit) This has also become a very important "band preview" device as well. It holds up well in strong transmitter fields. I expected I like it!

This has also become a very important "band preview" device as well. It holds up well in strong transmitter fields. I expected damage at high transmitter power, but so far nothing. It just keeps on ticking! :) I had problems with a WIN 7 install originally. Something was wrong in that original OS. Same machine but upgraded to WIN 10 Pro, and both SDR# and HDSDR work perfectly now. I expected possible damage at high transmitter power, but so far nothing.

Same machine but upgraded to WIN 10 Pro, and both SDR# and HDSDR work perfectly now. What, $20.00 or $25.00 plus the upconverter @approx: $45.00 and you have quite a bit you can do. I really like it for ham radio but recently using the aircraft tracking sw. has really been "enlightening!"

Without expensive laboratory equipment I have no elaborate details to mention, what I can say is that I had no trouble setting it up (I tried it out on four separate systems running Linux; two desktops, two Raspberry Pi... 4B/1G & 5B/8G, 'Bullseye,' 'Bookworm,' 'Bookworm,' & 'Ubuntu 'Noble,' respectively). It seems happiest running on Debian (12 'Bookworm'). The software available for it is mostly of the free and open-source variety, and the more graphically-intensive software is what will use up more RAM than the device, itself. Tuning-in local FM radio stations was no different from using the FM-tuner in our living room, the receiver sensitivity and selectivity were both en par with our (analog) FM-tuner. (Selectivity quite possibly is better with this device, mostly because of modern digital filter design in the IF-section/stages.) With regard to the amateur radio spectrum (or spectra), VHF works just fine; namely, there's plenty of activity on two meters... it's hit and miss finding activity on UHF, and one won't find much of anything below 24 MHz without mixing it down. (The antenna for the DX bands 160m - 10m is what will cost several dollars extra, this kit supplies an adequate antenna to get one started.) For a first try, this SDR-receiver is a good starter for anybody who's curious and wants to examine yet another angle to radio technology (and the price is right).

This is a strange gizmo. These USB sticks (in general) were not originally made to be used as SDR radios. They were designed to be used for Digital TV reception, with that market not even being in the USA. So of course, someone decided that they could work as a very wide band radio, or a type of extreme TV tuner that you would tune in like a shortwave radio, but you would tune it on your computer. For a low price, you get a mostly respectable radio tuner that covers the same range as a digital scanner, but you work this like a shortwave radio on your computer. You can use this as a scanner, (I have) but it will not scan channels and and digital/trunk scan requires special programs even more difficult. And Two of these. The package includes a small telescoping antenna, an adapter plug for using a different antenna, the tiny remote (not used for SDR) and a suction cup to join to the magnet mount antenna. And? That's it. No booklet, no box, no instructions. FYI...No Instructions!!! This is a Do-It-Yourself Gizmo. That is why I give this 4 stars. Okay, Amazon sent me an email from NooElec, which had a link to Setup information and basic Instructions. But...this is a warning here....this is an Experimenter's Device! It is Not Plug-N-Play in any form whatsoever. Use at your own Risk! You may get this to work as an SDR radio under the right conditions (under a full moon) on certain computers, on certain nights. Or you may not. You also don't get any Windows drivers for this and the drivers that Windows will try to setup for you will not work at all for SDR use. Windows will find/load these and then you are hosed. Won't work. You have to remove the Windows driver and install the specfic SDR driver for it, before Windows beats you. This driver has to be downloaded prior to you attempting to install this device and so forth. Did I mention, no instructions? When you make it this far, you download a program called SDR Sharp and if all goes well, it works as it should under Windows. But that is if Windows and SDR Sharp finds/recognizes the USB stick at all. At this point you will need hours of trial/error to Get It All To Work. Because the SDR Sharp program has a number of adjustable parameters (RF Gain) etc, which you will never comprehend and thus keep trying things in vain, but nothing works. Because you did not assign it to a USB port in the "Device Field" yada, yada, yada. And the Linux program GQRX is just as much fun. I use that as my main tuner with Linux Mint/Ubuntu. And it works as Good as SDR Sharp does in Windows, mostly the same thing. So for the price, you get a really fun gizmo. Once you set it all up (not easy) you have a very wide range radio tuner for Experimentation. You can see RDS FM radio data, you can see signal modulation/deviation/audio bandwith /subcarriers 19khz pilots, etc. Geek signal stuff. But this is a Very, Very, Steep Learning Curve to get here. Give it a few days of trial/error to even get it to work at all. Then a few days of adjusting parameters to make it sparkle. Then you've really got a Super Cool "Experimental RF Tuner" that will amaze you with the engineer's view of signals.

Come dongle SDR non c'è che dire, ma in base all'utilizzo va utilizzata un'antenna esterna più "seria". Con le frequenze 1090 invece funziona discretamente (all'aperto), si riescono a tracciare bene i segnali adsb. Ottima la ricezione della banda FM, audio cristallino e stabile. Non ho riscontrato problemi di saturazione e/o surriscaldamenti anche con uso intensivo e gain alto. Ottimo per chi vuole iniziare senza spendere un patrimonio. Usato con sdr# funziona bene. Per utilizzarlo vanno usati i driver "modificati", al momento dell'acquisto riceverete una mail con tutte le istruzioni.. PS. non ho avuto ancora modo di testare la chiavetta per ricevere il dvb-t.

Well built,and solid. Works a charm and mist impressed with ability and what's included making this amazing value for money and extremely educational and practical. Diagnosed a weather sensor fault with this and also an issue with heating thermostat, extremely cool to do that at this price point. Works very well upon a Raspberry Pi and just can't go wrong. Good intro device for SDR and then some. So good that I may buy another and definitely one of their more advanced models they also make.

Simple, easy and very cheap but does the job perfectly!

Puedo sintonizar la radio y usarlo para detección de trazas de meteoros.

Purchased as a USB TV tuner for my Linux (Ubuntu) NUC. Was detected by NextPVR software instantly, and works well with no issues. It's just a pain to also have to order an antenna adapter (for Australia - MCX to either F-type wall plug with the screw tip or PAL female to use with an existing cable).
