Product Description
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.

Customers like the performance of the tuner. They mention that it works well to receive signals across a wide span of frequencies, and that it's great when setup properly indoors. It works great for software-defined radio applications, and has a range of about 100mi. It's a neat little toy, but it'll be a bit tricky to pick up.

Customers are mixed about the ease of installation of the radio dongle. Some mention it's easy to setup and use, with no added setup required. The software is pretty straightforward, while others say that it'll take a lot of time and effort to set up. The learning curve for the software was steep, but worth it.

Customers are mixed about the signal strength of the tuner. Some mention that it can tune into an incredible range of radio signals using open source software. The antenna is enough for local FM, VHF, and police radia reception. However, others say that the audio is flat, the stock antenna is kind of deaf, and the dongle without external antenna is virtually deap. The SDR reception is quite amazing, but some customers say that it's not super accurate on frequency and has drift tendencies.

There was a problem filtering reviews right now. Please try again later.
ordered 2 for 2 separate rigs, both had the same offset of 15ppm to dial in, and drift is running at +0.01/0.02 to -0.01/-0.02ppm. I would suggest getting a usb extension cable to move it away from other electronics, as they do receive signals pretty good. Had one fairly close to a tv, and learned I'm going to need a new tv soon..(I noticed some interference when adjusting the tv volume. Gotta love the waterfall in those sdr programs!) So far, these two are working flawlessly! Reception for sdr use? I can't complain. The offset is real close to the mark, and drift is very tight. Much better than some of the other rtl sticks of the same style I have tried! Running them on 6' usb 2.0 extension cables. They run a little warm, but nothing at all drastic. About as expected, and comparable to any other rtl usb stick, as far as the temperature goes... As with any radio signal receiver, the better the antenna, the better the reception, but the included antenna seems to work just fine for general use. Everything seems to be of decent quality, so I would say, you would be happy with the purchase. Both of mine shipped from 2 different locations, and both are pretty identical in every way. I'd have to give the quality control in production a thumbs up!
For use as a cheap scanner, the supplied antenna works fine(depending on your location and surroundings you mileage may vary), ADSB, ACARS, no problem, FM reception is great, if you want to do other things such as listening to HAM bands and such, I'm sure you "could" with the supplied antenna (given the right conditions) , but I would recommend getting the proper antenna for the frequency range you plan to operate it in. The proper antenna for your use, makes a world of difference. Once you dial in the offset, and use the correct antenna for your application, you shouldn't have any problem. I can't stress that enough, not all antennas are created equal. Aside from the proper antenna for your application, would be placement.....Higher the better, more unobstructed the better.
Now, enough with this gibber jabber... I'm going to go play with my new toys some more!
These models work so well, I now own 6 of them for various purposes. They are fantastic. Depending on what you are hoping to receive, you may want to invest in a better antenna as the one that comes with it is an extremely wide-banded antenna, but works for most situations.
10 out of 10, highly recommend. There are reviews out there that say this is "garbage", if you know how to use them, and are using the proper software, these are a life saver. I'm hosting Broadcastify streams for 6 counties using only these devices.
First, a couple of nits: the software that you can get for these is not exactly intuitive. I had some minor trouble getting SDR Sharp up and running with this device. The antenna connector is miniscule; I'm thinking this unit would be helped a great deal with a better antenna than the stock unit, but it's going to take some searching to find an adapter to convert the antenna port on the unit to a more common size like BNC or SO-239. Neither one of these issues is a show stopper, and if you get into this with the idea that it is for experimentation, then you'll be satisfied with what you get.
One disappointment: if you are interested in eavesdropping on your local emergency services with Unitrunker and they are using the newer trunked multiplexing 800MHz systems, one of these units is not enough. You will need two: one to monitor the control channel, one to monitor the individual trunked frequencies. I didn't realize this when I made the purchase, and I'm waiting for the right opportunity to buy my second one so I can pick back up where I left off with that idea. With two of these units and Unitrunker software, you'll have a police/fire scanner on the cheap.
But other than those things, this is a great little receiver. I was able to spy on the ADS-B aircraft location reports, tune local radio stations, listen in to a few Ham radio transmissions (quality was not so good on those, I'm thinking it's the antenna) and more with just the included antenna and some freeware I downloaded off the web. (SDR Sharp, Cubic SDR, HDSDR, etc.) Let me be clear: the included antenna is seriously cheesy, and it's a very poor substitute for a more substantial, and possibly homemade unit. But it's good enough to pull in strong signals to prove the thing works.
If you've done your homework, you will know that these units were originally designed to receive European digital television signals, and that they have been "hacked" via software to make them a more broad-spectrum receiver. (They are useless for U.S.-spec television, by the way.) As such, they include a credit-card sized remote control that you might as well just throw away when you get it; there's no use for it here. So this is not a simple, finished product that you just plug into your computer and use; you have to tinker with it to get the capability out of it. As I mentioned, I had some trouble with getting some of the freeware software to run on my Win10 laptop; the problems were driver issues that I managed to overcome with lots of help from my research assistant, Dr. Google. If you are a radio amateur with some experience, this will be a cool thing to play with. If you're more like me, a radio amateur n00b, you might have to futz around a bit. More's the fun!
