The perfect device for learning software defined radio, on the cheap. Amateur radio, ADS-B, police & fire scanning, trunking, satellite images--you name it, this little guy can probably do it. Outperforms many devices 10x its cost!
These units are based on the R820T tuner IC made by Rafael Micro. As such, they have a frequency capability of approximately 27MHz-1700MHz, though this can vary somewhat from unit to unit. There is also an RTL2832U IC on board of course, which acts as the demodulator and USB interface.
The connector type on the antenna and USB board is MCX--male MCX on the antenna, female MCX on the SDR.
We perform extensive QA on every batch sold. As with all our SDRs, we guarantee antenna protection will be present so that your new investment will not be quickly destroyed by spurious ESD.
SOFTWARE DETAILS
Full compatibility with a large array of software packages, such as MATLAB, HDSDR, SDR Touch, SDR#, Planeplotter--too many to list. MathWorks and Nooelec have coordinated to bring MATLAB support for our SDR receivers. The RTL-SDR radio support package enables you to design wireless receivers using real world signals. Using Communications System Toolbox in conjunction with an RTL-SDR USB radio, you can design and prototype systems that process real-time wireless signals in MATLAB and Simulink.

I like to listen to my local law enforcement and emergency responders and this SDR allows me to listen to their communications in real time. Works better than expensive name brand police scanners.

Not too impressed with the seller.. I received it after paying the full listed price to find no remote.. and no fact/data sheets.Sent an email, the reply was that they "tried" but couldn't change the ad.. "They and Amazon were working on the problem" [though every other seller on Amazon has their version listed with remotes] and that it only worked on the video playback. really....... Not really a big fan of any biz that lies to my "face".. I won't be back again when the need arises...

This is a software defined radio RECEIVER. I works extremely well once you have the drivers and software properly installed and has features that usually cost much, much more. I a 71, have forgotten more about radio than I ever understood (*) and have learned a bunch from messing around with the NooElec RTL-SDR. I have a MAC and the first thing I did was to install a MacPorts driver and then Cubic SDR software. My "test" band was commercial FM and the dongle performed far beyond expectations...and my abilities..When I comes to Amateur Radio, this is the most cost effective radio equipment I have bought. I recommend this to EVERYONE who wants to learn about SDR and who wants an awesome way to listen to Shortwave, CB, the Amateur Bands, Aircraft and Marine Bands, etc., etc. Code, sideband (U and L,) I/O. and a bunch of other modes. 73, KW4EC

Wow. Just wow. I grew up engrossed in electronics and radio. I grew up with old fashioned radios. The big deal was having memories where we could "scan" multiple frequencies, one at a time, naturally. The holy grail device was a spectrum analyzer, which was hugely expensive.And now we have this SDR age. Wow!! It's almost too much to take in. The revolutionary step of going from monitoring one frequency and mode at a time to what is basically a spectrum analyzer on steroids is incredible. And at this price!I was skeptical due to the price, and the fact that computers generate large amounts of RF noise especially when there is a physical connection. My mind thinks "oh it's so small therefore it won't have much or any filtering hardware", because I'm still getting used to the concept of "oh, well, we'll just do much of what was once done in hardware, in software". I've been pleasantly surprised.How this will all work out for you depends heavily if not entirely on what software you use. The easiest route for me was Kali linux with that software that starts with a Q and is four letters long (why do open source folks use such silly names nobody can remember??). Seeing the spectrum pop up like that was sort of a dream come true, much like the dream of a spectrum analyzer.At first I used the antenna that came with it. I already knew this was very very minimalist, but also very portable. I had many other antennas around, but wanted to see how this one did. For me it was pretty pathetic, but is minimally acceptable for VERY local signals. For instance the police and fire station is about three blocks away and that was still hammering me so hard that I could actually see the 2nd and even 3rd order harmonics on the display. So cool!Then I started using better antennas. First a mobile for 144MHz and 440MHz. Nice upgrade there, especially since I already had it. The best update however was by using a discone antenna from Radio Shack (I really think this is the ONLY thing they make that's good these days). That changed everything. The incredible world that was opened up to me really blew my mind. Overkill really. It even allowed me to do ACARS -- And that's with the antenna indoors.At this price how can you go wrong? Do it!

For a cheap SDR receiver it works great. Just keep in mind that's exactly what is, a cheap receiver. You will not get nor should you expect to get high quality ham radio receive. This unit works well with SDR# on a Windows7 64bit machine, I have had no issues with it at all and for $20 I have well gotten my money's worth. I don't see it mentioned so I will say the antenna is approx 6inches tall from base to tip, and the antenna wire is about 2ft long with an MCX connector. I did open mine and verified it does in fact contain the R820T chip and a protection diode on the input. I have seen receive range from 23.9Mhz to 1900Mhz with no gaps in coverage. Setup is fairly easy and radioreference is a wealth of information to help you out. BTW if you intend to use this with unitrunker to track voice you will need 2 dongles.
