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!
This custom Nooelec SDR is a modified DVB-T USB dongle tuned for SDR usage, including upgraded crystal, capacitors and inductors compared to generic devices like those sold by competitors. This results in a lowered noise floor, increased stability and improved longevity.
These units are based on the R820T tuner IC made by Rafael Micro. As such, they have a frequency capability of approximately 25MHz-1750MHz, 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. There are plenty of adapter and adapter cables available in our store if you want to connect your favorite antenna!
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.
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

When I first unboxed the product, I tested it on my desktop computer. Every frequency above 120 mHz was inaudible and provided no signal. I quickly realised this was no problem of the manufacturer, nor was it a faulty product, the PSU in my computer seemed to be generating interference above those frequencies.
I then moved on to testing it for its intended purpose and what I got out of such a small device was incredible. I was able to pick up radio signals from upwards of 20 miles away depending on where it was mounted and the TV aspect also worked flawlessly too.
The reason for the 4 stars instead of 5 is purely down to the heat generated by the item. The little stick gets super super hot after quite a long use which makes it quite difficult to remove without a physical burning sensation. This usually isnt an issue however because it takes about a minute or two of sitting there to cool down again.
I intend to experiment with the positioning of the aerial - it's currently on my desk with no line-of-sight and still picks up signals fine - but as an SDR dongle this little device is a must-have for anyone interested in capturing radio transmissions that are all around us. Highly recommended.
UPDATE 1 Oct 19: I have since contacted NooElec customer support who have been incredibly helpful and prompt in their replies. They have confirmed that the device has likely failed - something of a rarity. I have increased my rating from 1 star to 3 stars based on the positive customer service and will review again when the device is replaced.
The case seems very cheaply made, but it's got a nice texture to it. The size of a big thumbdrive, antenna is rugged and solid, has a magnetic base so you can stick it to stuff... In my case, my computer tower.
I use SDR' Sharp to listen to radio. It works flawlessly, it did take a bit of wrangling to get the drives working in Windows... But there are several tutorials out there, don't worry.
All in all, for a starter like me, I think this is a great way to get into SDR. It's cheap, cheerful and definitely does the job.
Note: You will need to calibrate your ppm (frequency error correction) to make the best use of it. Lots of guides online on how to do this.
